In October 2013, the protection status of the Nevado de Toluca, Mexico’s fourth highest peak, was downgraded from National Park to Wildlife Reserve (Area of Protection for Flora and Fauna).

On paper, this is a significant downgrade that may now open the door to greater economic activity in the former National Park area with adverse environmental consequences. In practice, it might turn out to be a blessing in disguise and herald the start of a more pragmatic approach to environmental protection.

Is this good news or bad? This post considers some of the possible implications of the volcano’s recent change of status.

El Volcán Nevado de Toluca

El Volcán Nevado de Toluca

Background:

The Nevado de Toluca (also known as Chicnautécatl) is Mexico’s fourth highest peak, with a summit elevation of 4680 m (15,354 ft) above sea level. Located in central Mexico, southwest of the city of Toluca (the capital of the state of Mexico) and 80 km (50 miles) from Mexico City, the Nevado de Toluca is one of the most accessible volcanic peaks in the country. During the warmer months, regular vehicles can be driven very close to the volcano’s crater with its small lakes. During cooler months, when snow blankets the top portions of the mountain, the access road is popular with Mexico City families wanting to show their children what snow looks and feels like.

The area was granted National Park status in 1936, during the administration of President Lázaro Cárdenas, at a time when deforestation threatened to undermine the mountain’s ability to capture rainwater and be used as a water source for Mexico City and Toluca. (1936 was an important year in the history of environmental protection in Mexico because it was when the International Parks Commission was established which led to a series of protected areas–National Parks, Wildlife Areas and Forest Reserves–being established on either side of the Mexico-USA border).

The decree establishing the Nevado de Toluca National Park called for the expropriation of all the land around the volcano that was over 3000 m in elevation. The total area involved was about 536 sq. km. (207 square miles). While, for a variety of reasons, this expropriation was never fully implemented, deforestation of the volcano’s slopes was halted and tree-cutting banned.

In the succeeding decades, settlement expansion gradually ate away at the lower slopes with the result that the original National Park area now houses more than 5000 inhabitants in at least 16 distinct villages.

The newly designated Wildlife Reserve has a nucleus, centered on the crater, of 1.9 sq km, surrounded by a buffer zone of 51.7 sq. km.

A draft of the management plan for the Wildlife Reserve has been published by the National Commission for Protected Natural Areas (Comisión Nacional de Áreas Naturales Protegidas, CNANP) and made available for public consultation. The statuary 60-day consultation period began in mid-November.

The draft management plan [Map and plan both dated 5/11/2013] has met with considerable criticism in the popular press. The main issue is whether or not any such plan, however well intentioned, will be effectively enforced.

Several journalists have highlighted the very real danger that the new status will allow changes of land use in the former park that could lead to serious environmental degradation. The possible expansion of mineral extraction and of tourism within the Wildlife Reserve are of particular concern.

Mining

In “Se tolerará la minería dentro del Nevado de Toluca“, Paris Martínez looks at the situation of several mining operations in the former park currently quarrying volcanic sand and gravel. Only one of these companies apparently had the requisite permit from the State of Mexico to quarry within the National Park area. The draft management plan allows all the quarries to continue operating for at least five years. Effectively, as Martínez points out, the change of status of the Nevado de Toluca means that mining operations that were operating illegally within the park are now “regularized”, for at least five years.

The main existing sand and gravel quarries are: El Atorón and Loma Alta in the municipality of Zinacantepec La Loba, El Capulín, Las Lágrimas (the only one with a state permit) and El Varal in Temascaltepec.

There are also reported to be many smaller illegal quarries extracting tepojal, a volcanic deposit similar to pumice, used in the construction industry. Unsupervised and unauthorized extraction is especially prevalent on the southern and eastern sides of the Wildlife Reserve.

Local residents say that quarrying, together with the construction of the access roads required to access the quarries, has resulted in serious environmental damage to the slopes of the volcano. Specifically, quarrying activities have led to:

  • deforestation
  • erosion, soil loss, degraded hydrology
  • loss of soil water absorbing capacity
  • particle emissions
  • loss of slope stability
  • visual pollution

The impacts of quarrying are not confined to the slopes of the volcano. The increased erosion of the lower slopes has led to local streams having to cope with a higher sediment load, reducing their capacity to carry the heavy rainy-season precipitation. This has led to flooding damage downstream in municipalities such as Tenango del Valle, Calimaya and Rayón.

The management plan appears to lack a clear pathway for the regulation or limitation of quarrying activities. At the same time, it calls for short-term remediation of areas that have been subject to soil degradation, but only for former mining areas that are not currently being exploited. It does nothing to reduce soil impacts in areas where quarrying is ongoing.

While the management plan does not discuss how or when the quarries might be closed, it does propose establishing workshops to develop “alternative productive activities” for the owners of small quarries, to provide them with an alternative source of income. However, the workshops are only mentioned as part of the long-term plan, ie to be introduced at some point at least 5 years down the road.

What’s more, only one alternative productive activity – public use, open-air recreation and tourism- is actually mentioned in the plan, alongside those activities that would provide products or services for tourism. Surely the final version of the plan should also suggest other viable options?

The plan calls for compensation for the owners of property where quarrying is halted, and who opt for alternative activities. However, this too is only mentioned as part of the longer term plan, so many landowners may well be tempted to start mining in the interim, in order to be able to claim compensation in a few years’ time!

Tourism

The decision to change the protection status of the Nevado de Toluca was based on a commissioned study that showed the area had potential for “intensive tourism” and “private infrastructure”. The study identified potential “tourism nuclei” or “sites for intensive tourism” where the construction of cabins was considered “feasible”. Following criticism and opposition that included almost 30,000 signatures on a change-org petition, the draft Management Plan does not use terms like “intensive tourism” and states that “tourism developments and ski runs may NOT be built in the area”, nor may subdivisions, hotels, golf courses or weekend homes.

The draft plan calls for “low-impact tourism” which is environmentally aware, defined as being suitable for activities such as hiking trails, camping and bird-watching. The plan allows for this form of tourism to be developed in most of the core area of the crater of the Nevado de Toluca as well as in a 3-square-kilometer section on the slopes of the volcano. The plan also allows existing settlements (whose area is not precisely defined) to develop tourism infrastructure; this could easily result in some short-term land-grabbing. Equally, precisely what counts as tourism infrastructure is not clearly defined.

Accepting that the National Park was never adequately patrolled or regulated, then if the new Wildlife Reserve Management Plan is tightly written and backed up by effective monitoring and the enforcement of regulations, then the volcano’s change of status may yet prove to be the best way to preserve the mountain’s unique character.

The draft plan is a valuable step forward, but Geo-Mexico hopes that the final Management Plan will address the many concerns raised in the press, to the benefit of both the volcano itself and its local residents.

Thanks to Arq. Ricardo Warman for first alerting us to the Nevado de Toluca’s change of protected status.

2013 Mexico Peace Index: Mexico becoming more peaceful

 Mexico's geography in the Press  Comments Off on 2013 Mexico Peace Index: Mexico becoming more peaceful
Dec 142013
 

The Institute for Economics and Peace (IEP), an independent, non-profit research organization dedicated to promoting a better understanding of the social and economic factors that develop a more peaceful society, has released its first Mexico Peace Index. The 2013 Mexico Peace Index (MPI) is based on a similar methodology as previous IEP indices, including the United States Peace Index and the United Kingdom Peace Index; however specific measures were included to better reflect the specific Mexican cultural and national context.

For the Mexico Peace Index, seven indicators were used to analyze peace: homicide rates, violent crime, weapons crime, incarceration, police funding, efficiency of the justice system, and the level of organized crime.

The study was performed with the guidance of an Expert Panel representing various institutions such as IMCO, CIDE, Mexico Evalua and INEGI. The Mexico Peace Index 2013 uses data provided by INEGI and the Executive Secretariat of the National Public Security System (SESNSP).

The headlines

  • Mexico Peace Index finds that peace improved 7.4% in past two years
  • The two-year improvement in peace was primarily driven by a 30% decrease in organized crime
  • Most peaceful states experienced an annual GDP growth of more than double the least peaceful states
  • Oaxaca, Chiapas, and Yucatan have the most improved levels of peace in the past decade
  • Mexico has the greatest potential in the world to overcome its current levels of violence and build a more peaceful society, with a strong business environment and high levels of human capital
  • The eastern region of Mexico is the most peaceful; the northern region the least

The 2013 MPI provides a comprehensive assessment of peace in Mexico detailing the level of peace in each of the 32 states over the last 10 years and an analysis of the costs associated with violence as well as the socio-economic dimensions associated with peace.

mpi-coverThe study finds that there was a 7.4% improvement in Mexico’s peace scores in the last two years, driven by decreases in organized crime, violent crime, and weapons crime. However, over the past 10 years Mexico experienced a marked increase in direct violence, with peace declining by 27%. A key factor was the 37% increase in the homicide rate since 2007.

The 2013 MPI presents comparisons between the states and the regions of Mexico, and finds that the states with the highest levels of peace are: Campeche, Queretaro, Hidalgo, Yucatan and Baja California Sur while the five least peaceful states are: Morelos, Guerrero, Sinaloa, Chihuahua, and Quintana Roo.

The study finds that Oaxaca, Chiapas and Yucatan experienced the most substantial increases in their levels of peace during the last decade. Oaxaca improved its score by 22% and Chiapas by 17%.  These states were found to be relatively peaceful in comparison with other areas of Latin America and North America. Campeche, for example, has a level of peace comparable with the states of New Mexico and Delaware in the United States.

Regionally, the research finds that the eastern region of Mexico is the most peaceful, while the northern region is the most violent.

Analysis of federal funding to state police (Fondo de Aportaciones para la Seguridad Publica) finds that increases in police funding are related to crime reporting rates, with increased funding improving the public’s relationship with the police.

The direct cost of violence to the Mexican economy is 3.8% of GDP, while the indirect costs amount to 12% for a total 2.49 trillion pesos (15.8% of GDP). Under optimal conditions, if there was no violence in Mexico, the economy would have the potential to improve by up to 27%. This figure includes direct and indirect costs and the additional flow-on economic activity that would eventuate from new money being added to the economy. The study highlights that if all the states of Mexico were as peaceful as Campeche, the most peaceful state in the country, Mexico would reap an economic benefit of 2.26 trillion pesos.

The most peaceful Mexican states in 2003 experienced the strongest economic performance in 2012. Over the past 10 years, these states’ GDP increased by 9% versus 4% in the least peaceful states.

Steve Killelea, founder and executive chairman of IEP said: “Compared to other countries with a similar level of conflict and development, Mexico has the greatest potential to increase its peace on account of the strength of the structures, attitudes and institutions that sustain peace in the long term.” He added that: “This research aims to provide the evidence base and data for a broader policy debate about how to reduce violence in Mexico”.

Mexico’s standing in regards to positive peace is encouraging: the country has a strong business environment, performs well on measures of human development, and ranks better than world averages on education.

Factors impacting peace in Mexico

It is well known that the increase in the levels of violence in Mexico has been a consequence of the war against drug trafficking, but there are other key factors at play.

The number of firearms smuggled into Mexico increased substantially during the last decade, almost three times higher in the period 2010-2012 than between 1997 and 1999.

As a consequence, the weapons crime indicator, which measures the number of offenses involving the use of weapons, recorded a significant increase of 117% per 100,000 people during the last decade.

The measure of the efficiency of the justice system has recorded a significant deterioration. In some states up to 95% of homicides remain unpunished.

In addition, the public perception of corruption is very high and one of the greatest challenges facing Mexico.

Prison capacity is overstretched with a Mexico Evalua 2013 report stating that 52.4% of prisons in the country are over-crowded and house 74% of the prison population in Mexico.

There is a high level of unreported crime in Mexico. According to data from the National Survey of Victimization and Perception of Public Safety 2012 (ENVIPE), only 19% of theft, 10% of fraud and 10% of extortion cases are reported.

It is important to address all of these key challenges in order to reduce violence and realise the social and economic benefits of peace in Mexico.

Today is 12 December, the feast day of Our Lady of Guadalupe, the beloved indigenous patron saint of Mexico and much of the Americas. This seems like a good excuse, if ever one was needed, to revisit the “Gender Gap” in Mexico. The gender gap assesses the “gap” between females and males for a number of variables, but should not be taken as reflecting the quality of life of females in different countries.  For example, the gender gap between women in Japan and Japanese men is very large, even though Japanese women enjoy a relatively high quality of life.

In “The Global Gender Gap Report 2013″, the World Economic Forum (WEF), based in Geneva, Switzerland, placed Mexico 68th of the 136 nations included in the study. Between them, the 136 nations house 93% of the world population. Mexico has risen 16 places in the rankings since 2012, meaning that the gender gap in Mexico is narrowing, even if there is still a long way to go to reach gender equality. (It is worth noting that Mexico has been climbing steadily up the rankings for several years, from #98 in 2009, to #91 in 201, #89 in 2011 and #84 in 2012).

Of the 136 countries studied for the 2013 report, Iceland had the smallest gender gap, for the 5th year running, followed by Finland, Norway and Sweden.

Among Latin American nations, Nicaragua had the smallest gender gap (placing 10th in the world), with Cuba, which has the highest female participation in government, coming in 15th and Brazil remaining 62nd. Other notable placings were Germany 14th, and South Africa 17th.

The Gender Gap Index is a composite index comprised of a number of variables grouped into four key areas:

  • health and survival
  • educational attainment
  • political empowerment
  • economic participation

As noted in our summary of the 2012 Gender Gap Report, Mexico ranks #1 in the world, tying with several other countries, for the health and survival subindex. This means that Mexican females are unsurpassed with respect to sex ratio at birth (female/male) combined with female life expectancy (female/male).

For the other subindexes, in 2013 Mexico ranked #36 for political empowerment and #70 for educational attainment, but a lowly #111 for economic participation.

Geo-Mexico agrees wholeheartedly with Klaus Schwab, founder and executive chairman of the World Economic Forum, who called for renewed efforts to ensure gender equality, saying that, “Countries will need to start thinking of human capital very differently – including how they integrate women into leadership roles. This shift in mindset and practice is not a goal for the future, it is an imperative today.”

Mexico City explores deep water aquifer

 Mexico's geography in the Press, Updates to Geo-Mexico  Comments Off on Mexico City explores deep water aquifer
Dec 092013
 

Background: The Valley of Mexico is an interior basin about 9000 square km in area. The basin floor sits at an elevation of 2200 meters above sea level and is surrounded by mountains that rise up to more than 5000 meters above sea level. It receives around 700 mm of rainfall a year, with a rainy season from late May to September.

The basin was originally the site of several lakes and marshes, and much of it is underlain by lacustrine sediments up to 100 m thick, beneath which are alluvial sediments up to 500 m thick (see geological cross-section below). These sediments are interstratified with layers of volcanic basalt. Beneath the alluvial sediments are 100 m to 600 m of volcanic deposits, which form the principal Mexico City aquifer (found about 500 m to 1000 m below Mexico City).

As Mexico City has grown, and water demands have increased, this main aquifer has been greatly overexploited, leading to a drop in the level of the water table underground, accompanied by ground subsidence that has had serious consequences for Mexico City:

Feasibility study of a deep aquifer

The National Water Commission (CNA) and Mexico City Water System (SACM) are undertaking a 3-year, 23-million-dollar feasibility study to assess the potential of an aquifer that lies more than 2000 meters below Mexico City. (Our earlier, initial report about this aquifer is here).  The project includes experts from Pemex, CFE and UNAM’s Institute of Geophysics.

Initial exploratory wells have shown that the deep aquifer’s water quality is superior to that currently derived from the overexploited shallower wells that extend to depths of around 800m.

It is hoped that the feasibility study will confirm that water from the deep aquifer could be an additional viable source of freshwater for the city. Assuming the deep aquifer is hydrologically independent of the shallower aquifers, this  would not only reduce the need to pump water from the shallower aquifers, but would also avoid the ground subsidence resulting from continued shallow-water extraction. The feasibility study will assess whether or not the deep water aquifer is “fossil” water or is still being recharged from precipitation and underground throughflow. If it is being recharged, the experts will calculate its recharge rate to determine the aquifer’s maximum sustainable yield. (The maximum sustainable yield is the “additional groundwater output from the system which will cause minimal and acceptable levels of stress to the ecosystem with maximum benefits to the society and to the economy”).

The first test well is likely to be sunk in the Magdalena Mixhuca Sports City area, in the eastern part of Mexico City.

This potential deep aquifer source of freshwater could play a vital part in ensuring that future generations of Mexico City residents have a dependable and sustainable water supply.

Mexico’s consideration of utilizing deep water aquifers runs counter to the prevailing wisdom in the US where it has long been argued that deep water aquifers will be too costly to utilize for fresh water, will never be used, and are therefore more useful as a repository for waste and can be intentionally polluted.

As a result, as this Huffington Post article explains, “policy-makers often exempt these deep aquifers from clean water protections and allow energy and mining companies to inject pollutants directly into them.”  The article adds that, “the U.S. Environmental Protection Agency has issued more than 1,500 permits for companies to pollute such aquifers in some of the driest regions. Frequently, the reason was that the water lies too deep to be worth protecting.”

In the mid-sixteenth century, the Spanish Court was determined to acquire accurate information about everything being encountered in New Spain. This led to a series of censuses and accounts, including the Relaciones geográficas (Geographic Accounts).

The basis for the Geographic Accounts was a 50-question survey, sent to New Spain in 1577. The authorities in each administrative center were instructed to call a meeting of the “Spaniards and other natives in the district”, to find out everything they could about the area’s geography, people and history.

Of the 191 known responses to the 1577 questionnaire, 167 have survived in archives to the present day. Most of the original responses are housed in Spain, in either the Archivo General de las Indias in Seville or the Real Academia de la Historia in Madrid, while a further 43 responses form part of the Benson Latin American Collection in the University of Texas library in Austin. (The library’s webpage about the Relaciones geográficas has several links to images of sample pages and maps).

Map of Zempoala area from the Relaciones Geográficas

Map of Zempoala area from the Relaciones Geográficas (1577)

The accounts contain a wealth of information about population, relief, flora, fauna, economic activities and lifestyles. Some also include maps of the areas being described. However these early maps do not follow modern conventions in terms of having a uniform scale across the area being shown, or an orientation that is consistent in terms of compass directions. They are pictorial maps, where the scale varies across the map, and where areas are delimited, or places are linked, without apparent regard for direction.

One such map (see image above) depicts the area around Zempoala (Hidalgo). This is analyzed by Barbara E. Mundy, Associate Professor of Art History at Fordham University, in an online article, Mapping Babel: A Sixteenth-Century Indigenous Map from Mexico, published in The Appendix, a “journal of narrative and experimental history”. In the article, Mundy provides a detailed, step-by-step account of the map, with lots of additional related images and information.

Detail of map, showing Tepemayalco

Detail of map, showing Tepemaxalco

Mundy’s analysis reveals several “acts of translation” that have been made by the indigenous artist(s) presumed to be responsible for drawing the map.

For example, the artist(s) made the Spanish paper provided for the map more closely resemble its indigenous counterpart (bark paper), by joining sheets together to create the size they wanted for the map. In addition, unlike modern maps where the viewer is essentially static, with the map details arranged around them, indigenous maps demand changes of perspective, mobile viewers, who have to reorientate themselves depending where they are on the map in order to see things clearly.

Many of the images are a translation, perhaps of similar European images. For instance, like most towns on the map, Tepemaxalco is shown with “a conventional sign for a Christian chapel: a small building drawn in perspective with one side marked by a shadowing grey wash, topped with belfry and cross.”

The map also links the pictograph for each place name to its name written in alphabetic script. “The pictograph for Tepemaxalco (see image) registers some of its Nahuatl components: tepetl, ‘hill,’ maitl, ‘hand,’ xalli, ‘sand’ and co, ‘place of.’ Below, the name is written in alphabetic script, probably introduced by the Franciscans who evangelized this region.”

The dominant pictogram on this map is that for Zempoala (written “Cenpoballa” on the map). Mundy offers an interesting interpretation of this pictograph, which we hope to examine further in a future post.

After studying 22 countries with sizable retirement communities, International Living (a consultancy group) rated Mexico as the fourth most attractive country for foreigners to retire to in 2013, after Ecuador, Panama and Malaysia. The study looked at eight factors: real estate, benefits for retired people, cost of living, integration, entertainment, health, infrastructure and climate.

According to the US Census Bureau, there are 41 million people of retirement age in the USA. More than half of them have annual incomes of between 70,000 and 150,000 dollars, and they are expected, on average, to live to the age of 83; 80% are home owners. This number will swell to 72.8 million by 2030, 40% of whom may have difficulties maintaining their previous lifestyles during retirement. Given its proximity, this makes Mexico an attractive destination for many baby-boomers seeking a comfortable retirement lifestyle.

But where in Mexico will these retirees choose to live?

According to this analysis by the consultancy Aregional, there are 36 specific areas in Mexico where the real estate market is targeting US baby boomers seeking a place to retire. About half of these locations (see map) are in central and western Mexico. Locations in these regions include Guanajuato and San Miguel de Allende (both in the state of Guanajuato), Colima, Comala and Manzanillo (Colima); Chapala, Ajijic and Puerto Vallarta (Jalisco); and Nuevo Vallarta and Punta Mita (Nayarit).

Locations in northern Mexico important for retiree real estate include Rosarito, Ensenada and Los Algodones (Baja California); Los Cabos, La Paz and Loreto (Baja California Sur); Puerto Peñasco (Sonora) and Mazatlán (Sinaloa). [Kudos to RickS for noticing that Puerto Peñasco is not located very accurately!]

Retiree real estate is also prominent in several places in the south and south-east of Mexico, including  Acapulco and Punta Ixtapa (Guerrero); Huatulco (Oaxaca); Playa del Carmen and Cancún  (Quintana Roo); Puerto Progreso (Yucatán), as well as the cities of Campeche and Veracruz.

It is not known how many US retirees have already chosen to live in Mexico. While it is relatively easy to quantify the number of retiree tourists (those staying more than one night, but less than six months), it is impossible to accurately quantify the number of non-working, non-Mexicans who have chosen to relocate full-time to Mexico. Technically, these “residential tourists” are not really tourists at all but longer-term migrants holding residency visas.

Residential tourists already form a very distinct group in several Mexican towns and cities, with lifestyle needs and spending patterns that are very different from those of regular tourists. Their additional economic impact is believed to exceed $500 million a year.

A case study of residential tourism, and its pros and cons, in Chapala-Ajijic on the northern shore of Lake Chapala is an integral part of chapter 19 of Geo-Mexico: the geography and dynamics of modern Mexico.

Mexico’s Pemex is one of the most competitive oil firms in the world

 Updates to Geo-Mexico  Comments Off on Mexico’s Pemex is one of the most competitive oil firms in the world
Dec 022013
 

Despite the criticisms regularly leveled at it, Mexico’s oil giant Pemex is actually one of the most competitive oil firms in the world.

First, its costs of exploration and production are much lower than those of most other major oil companies. Pemex’s production costs in 2012 averaged 6.84 dollars/barrel (d/b) of oil equivalent, well below the costs incurred by international rivals Exxon (9.91 d/b), Chevron (15.16), Total (8.17), Shell (12.47) and British Petroleum (12.50).

pemexPemex’s exploration and development costs are also among the world’s lowest. They fell from 16.13 d/b in 2011 to 13.77 d/b in 2012, mainly due to the discovery of several new reserves. Among major players, only Shell had lower costs (11.75 d/b), with Pemex well ahead of British Petroleum (17.37 d/b), Exxon (19.31), Total (22.68) and Chevron (28.81).

Thirdly, as new fields are fully explored, Mexico’s proven oil reserves are expected to continue to rise for a number of years, from the current level of 13.87 billion barrels to 14.92 billion barrels by 2018. (During this period, Pemex will extract an estimated 6.64 billion barrels, but they will be more than replaced by anticipated new discoveries)

How important is Pemex to the Mexican economy?

One third of Mexico’s national budget comes from the petro industry, which accounted for 7.6% of GDP in 2012.

In 2012, Pemex invested 23.9 billion dollars in Mexico, appreciably more than the 19.2 billion dollars invested that year by América Móvil, Femsa, Walmart, Frisco, Cemex, Liverpool, Alfa and Mexichem, combined.

In terms of revenues, Pemex had revenues in 2012 of 142.4 billion dollars, greater than the 139.1 billion dollars in revenues of América Móvil, WalMart, Femsa, Alfa and Cemex combined.

According to a Bloomberg analysis, between 1973 and 2012, Pemex generated a cash flow (before tax and depreciation) that was 63% higher than the total cash flow of all the firms listed on the Mexican Stock Market. In 2012, the Ebitda (Earnings before Interest, Tax, Depreciation and Amortization) of Pemex was 88.2 billion dolalrs, compared to the combined 54.2 billion dolalrs of Ebitda for América Móvil, Banorte, Femsa, Walmart de México, Grupo Modelo, Cemex, Kof, Televisa, Peñoles and Alfa.

How important is Pemex in the worldwide picture?

According to Petroleum Intelligence Weekly, U.S. Energy Information Administration and U.S. Crude Oil Imports by Country, Pemex is one of the world’s five most important crude oil producers, after Aramco (Sauid Arabia), NIOC (Iran), CNPC (China) and KPC (Kuwait).

Pemex is the third largest oil exporter to the USA, after Canada and Saudi Arabia, but ahead of Venezuela and Nigeria.

Mexico has the world’s 13th largest crude oil reserves and Pemex has the world’s 15th highest oil company revenues.

Mexico’s proposed energy reforms, which will allow private sector firms more access to some parts of the oil and gas sector, will only serve to boost the competitiveness of Mexico’s oil industry. The major problems facing Pemex are not directly related to revenues or to competitiveness, but are the persistence of corruption and a lack of transparency.

How does Mexico’s unemployment rate compare to that of other countries?

 Other  Comments Off on How does Mexico’s unemployment rate compare to that of other countries?
Nov 212013
 

In a recent post, we looked at The pattern of unemployment in Mexico in 2013 and saw how states in northern Mexico have significantly higher unemployment rates than most of southern Mexico. In this post we consider international comparisons. How does the rate of unemployment in Mexico compare to the rates in other countries?

The OECD (Organisation for Economic Co-operation and Development) publishes harmonised unemployment rates for its 31 member countries. The OECD calculates Mexico’s harmonised unemployment rate for the third quarter of 2013 at 4.9%. This is quite encouraging, since the average for OECD countries is 7.9%. (Note that these figures do not include “underemployment”.) Mexico’s unemployment rate is more favorable than that of its NAFTA partners, Canada (currently 7.1%) and the USA (7.6%).

The OECD members with the highest unemployment rates are Greece (27.4%), Spain (26.6%),, Portugal (16.4%), the Slovak Republic (14.0%) and Ireland (13.8%).

Among OECD members, only South Korea (3.1%)  Japan (4.0%) and Austria (4.1%) have a lower harmonised unemployment rate than Mexico.

 

The pattern of unemployment in Mexico in 2013

The accuracy of Mexico’s unemployment statistics is frequently questioned in the media but INEGI, Mexico’s National Geography, Statistics and Information Institute, uses internationally accepted methods to compute various different unemployment indices. As in most countries, INEGI surveys are based on samples in urban areas, involving 80,000 interviews in more than 30 towns and cities.

The International Labour Organization defines “unemployed workers” as those members of the workforce currently not working but willing and able to work, who have actively sought work in the past four weeks. Note that the mere act of looking at newspaper or online ads is not considered sufficient evidence of “actively seeking work”.

Mexico’s economically active population in the third quarter of 2013 was 52.3 million people, a very slight (0.01%) increase on the comparable figure for 2012.  The figure represents 59% of the total population aged 14 and over.

INEGI statistics show that the under-employed population was 8.5% of all those with jobs. The unemployed population was 2.7 million, 5.2% of the workforce.

Mexico’s workforce is not gender-independent. 77 out of every 100 men are economically active, compared to only 43 of every 100 women. The workforce can be subdivided between primary occupations (6.8 million, 13.8% of the total workforce); secondary occupations (11.9 million, 24%) and the tertiary or services sector (30.6 million, 61.6% of  workforce), with the remaining 0.6% undeclared.

Out-migration from several southern and western states has significantly reduced unemployment. Several southern states are among those with the lowest unemployment rates in the entire country.

The highest rates of unemployment are mainly in northern Mexico, parts of which have seen on-going violence in the war against drugs. Workers flocked to these areas during the boom times of Mexico’s maquiladora program when firms were encouraged to set up “in-bond” factories in these states, enjoying the freedom to import components and export finished products. However, the slow recovery of the US economy has reduced demand for consumer products and many maquiladora factories have reduced their workforce, leading to intense competition for available jobs and a higher rate of unemployment.

What other factors influence unemployment and help explain the patterns shown by the map?

In an alliance with the Sonoran Institute, the National Geographic Center for Sustainable Destinations helped the region’s communities create the first transborder Geotourism MapGuide, covering northern Sonora and southern Arizona. The mapguide was published in 2007:

The maps  have vignettes of information about history, culture, geology and many other aspects of the region, making it a useful guide for geo-tourists. While some might argue about the choice of locations and attractions described on the maps, this is a useful addition to the background reading for anyone thinking of traveling to this region with some time on their hands to explore.

Surprisingly, the map has only a very brief and somewhat dismissive mention of the El Pinacate and Gran Desierto de  Altar Biosphere Reserve:

“Stand at the rim of this mile-wide volcanic crater and you may feel as if you’re on the moon. This land of ancient lava, sand, and cinder cones is sacred to the O’Odham people. Today, those on the Sonora side of the border call themselves “Pápago.”

About 160 kilometers (100 miles) north of Guadalajara as the crow flies is a wild and inhospitable arm of the Western Sierra Madre called the Sierra of Bolaños, a rugged northern extension of Jalisco most easily reached by light aircraft. The one way trip by road requires driving more than 320 kilometers (200 miles) from Guadalajara, half the distance being inside the adjacent state of Zacatecas. The Bolaños region has for centuries been an important silver mining area, and British capital and engineers left an indelible mark on the towns there.

The once-grand colonial mining town of Bolaños fits snugly between the river and the rocky cliffs into which the first mine shafts were sunk. Its numerous old stone buildings, often with ornately carved doorways and windows, make it a fascinating place to wander around. With judicious restoration, Bolaños could undoubtedly find its way onto anyone’s list of Mexico’s top mining towns to visit. The town’s hanging bridge (puente colgante) links Bolaños, on the edge of mestizo territory, with the Huichol Indian villages in the mountains on the far side of the river. Huichol artwork, including colorful beadwork, is on sale in several stores in the town and it is common to see traditionally-dressed Huichol Indians in the streets.

Mineral riches

Relatively little is known of the pre-Columbian history of the Sierra of Bolaños but the area was probably only sparsely peopled, perhaps by Tepecano Indians. By the beginning of the seventeenth century, Spanish adventurers had founded the town of Chimaltitán which later served as their base for both subduing the natives militarily and converting them to Christianity. They later founded the towns of Bolaños, a short distance to the north, and San Martín de Bolaños to the south.

By the mid-eighteenth century, the Spanish were in complete control and the Bolaños mines were producing between 2 and 3 million pesos worth of silver per year, or about 25% of the silver production in the whole of New Spain—a very considerable amount, bearing in mind that each peso was then worth about a dollar.

By the 1760s, 16,000 people lived here. Overlooking an attractive small park in Bolaños is the rococo Guadalupe Chapel (the church of San José), a gift to the town from Antonio de Vivanco, owner of several mines. In 1789, de Vivanco became Marquis Vivanco, Viscount of Bolaños.The prosperity of these times is reflected in the sumptuous architecture of the buildings in Bolaños that date from this period. Two particularly fine examples are the Casa de la Condesa, and Antonio de Vivanco’s former home, with its unusual frescoes, both on the street which parallels the river. Bolaños even boasted a two-story Royal Mint, with a lovely facade. Built on one side of the main plaza in the 1750s, this partially restored gem has an Austrian Hapsburg two-headed eagle carved in the stone above its main door. This royal crest may have inspired the local Huichol Indians to use two and even four-headed eagles (a head for each cardinal direction) in their handicrafts.

But the boom times of the 1750s were not to last for ever. Following a series of floods (the most serious of which occurred in 1757 and 1781), land disputes, the ever-increasing quantities of costly mercury required for smelting, and disagreements over mining rights, Bolaños’s first boom period came to an abrupt end. By 1798 the town was virtually abandoned. Its largest church, begun in 1778, still stands half-finished; today, this is probably the only place in the world where you can play basketball under floodlights in the shell of an ancient church!

A new company and British miners

British influence in Mexico quickly gained momentum following Mexico’s Independence in 1821. On 27 September 1821, Agustín de Iturbide entered Mexico City in triumph. Most gachupines (Spanish-born residents of Mexico) had fled with whatever assets they could muster back to Spain. The rest were expelled in 1829. Iturbide desperately needed funds, to pay his 80,000-strong army and to set up an administration but, after eleven years of war and chaotic politics, the nation was fatigued and the Treasury empty.

In order to stimulate the Mexican economy, Iturbide needed to revive the mines, many of which had been abandoned during the Independence War. However, the mines had drainage problems and needed large investments of capital. Mexico’s need, coupled with the aspirations and greed of England’s capitalists, proved to be an unstoppable combination. Between 1820 and 1824, no fewer than seven different mining corporations relying on U.K. capital were formed in Mexico. One of these was the Venture Company of the Mines of Bolaños.

The Bolaños Company commissioned a full inspection of their mines. This concluded that, given “modern technology”, a fortune in silver was awaiting exploration, with a potential profit of over a million dollars. The firm’s investors were happy to pour money into bringing British machinery and the ingenuity of expert tin miners from Cornwall to back up their intentions.

In the early days, it was difficult and even dangerous to travel to the mines. No fewer than 15 of the 45 Cornish miners who accompanied the first shipment of machinery for Bolaños in 1825, died through accidents or disease before taking up their posts.

Mine owners had their own agenda. Most insisted that their miners worked completely naked in an effort to thwart any attempted pilfering of ore. Miners grew ever more ingenious in trying to circumvent the rules. They were discovered concealing silver ore in their hair, hollowed-out hammer handles, their mouths and ears, and even, on one occasion, inside the disemboweled body of an overseer killed in an accident!

Despite all the problems the British were determined to succeed. They built a reservoir above the village of Tepec and then a five kilometer long canal, much of it underground, to bring water to the town of Bolaños. On the east side of the small church in Tepec, a camposanto (cemetery) was built specifically for the English miners and their descendants since they were not Catholics and should not therefore be buried in the town’s main graveyard.

To assist in drainage, the British assembled two massive hydraulic wheels, one 12 meters, and the other 14 meters in diameter. Their most important contribution, though, was to import a 32-ton steam engine from the U.K. It took 106 days for this engine to be hauled over the mountains from Veracruz. Locals say that the reason the San José church now has only small bells is because the large ones were melted down to make wheel rims to help move the steam engine.

Bolaños grew into a town of more than 30,000 people, with seven major mines in production, employing thousands of workers. However, despite the mammoth injection of British capital and technology, the company failed to extract enough silver to obtain any return on its investment. In 1842, amidst political rumblings after several accidents and a fire which cost the lives of more than 150 miners, and with the Mexican government delaying payments for silver bars “bought” by the Mint, the company was wound up and Bolaños once again echoed to the sounds of bird-song rather than of hammer, chisel and steam engine.

The town’s population declined to fewer than 5000. It became a ghost town, another casualty of the ever-changing fortunes of mining centers around the world. Various attempts to revive the mines in the late nineteenth century by North American interests came to nothing. At the end of the last century, a U.S.-Mexico joint venture mined successfully for some years but finally went out of production in about 1998. Today, Bolaños is still a small town, a mere shadow of its former self, though one offering a few small hotels and ample opportunities for adventure, eco- and cultural tourism.

Twenty kilometers south of Bolaños, down the valley and past Chimaltitán, is San Martín de Bolaños. The El Pilón mine, near San Martín, opened in the 1980s, is the only mine currently operating in the valley. By 2007, it had produced over 30 million ounces of silver, as well as some ancillary gold.

A visit to this remote corner of Jalisco provokes deep feelings of admiration for the courage and audacity of all those who chose to settle here, including the nineteenth century British immigrants who left a Europe torn by upheaval, in search of fame and fortune in Mexico.

Record avocado production and exports, 2012-2013

 Updates to Geo-Mexico  Comments Off on Record avocado production and exports, 2012-2013
Nov 112013
 

Mexico is the world’s largest producer and exporter of avocados. In the 2012/13 season, Mexico’s avocado orchards produced a record 1.3 million metric tons of avocados. More than 90% of Mexico’s avocados are grown in the state of Michoacán, where about 12% of all agricultural land is currently under avocado orchards.

Avocado-growing states in Mexico.

Avocado-growing states in Mexico

Avocado exports rose 33% to 643,000 metric tons, worth 1.2 billion dollars, also a new record. The main export market remains the USA which imported 518,000 metric tons between July 2012 and June 2013, to help satisfy a demand that has risen rapidly.

Total USA avocado imports in 2012-2013 from all countries were 40% higher than the previous year, and have risen over the past 15 years from 200,000 metric tons to 750,000 metric tons.

In 2012-2013, Mexico also exported 125,000 metric tons of avocados to Canada, Japan, Central America and Europe, a 32% increase over the year before.

The Federal Farming Secretariat has introduced a new national certification system for growers to help ensure consistent quality and reduce spoilage during transport. Many avocado growers are working towards increasing the number of orchards certified by Global Gap, a worldwide certification organization.

The landforms of the El Pinacate and Gran Desierto de Altar Biosphere Reserve

 Other  Comments Off on The landforms of the El Pinacate and Gran Desierto de Altar Biosphere Reserve

The breathtaking scenery of the El Pinacate and Gran Desierto de Altar Biosphere Reserve in the northern state of Sonora affords visitors a dramatic combination of two very distinct landscape types: volcanic landscapes (El Pinacate) in the east, and sand dunes (Gran Desierto de Altar) towards the west and south.

pinacate-map-googleVolcanic scenery (El Pinacate)

The eastern section of the Biosphere Reserve, El Pinacate, is a dormant volcanic area of around 200,000 ha (2000 sq. km), centered on the El Pinacate Shield (or Sierra Pinacate) which has 3 main peaks: Pinacate, Carnegie and Medio. The El Pinacate Shield is a composite structure, comprised of extensive, successive black and red lava flows, some more than 20 km long, seperated by desert pavement. The El Pinacate Shield boasts a wide array of volcanic phenomena and geological formations. Most of the lava is basaltic (alkaline) in composition, making it relatively fluid when molten; it is mainly of the aa (blocky) type, though some pahoehoe (ropy) lava is also found. The total volume of lava is estimated at between 150 and 180 km3.

Elegante Crater, El Pinacate

Besides the lave flows, the Pinacate area has more than 400 cinder cones (formed 1.2 million years ago) and several lava tubes. The lava flows and cinder cones are only a prelude to the most visually striking features in the reserve: 10 enormous, deep, and almost perfectly circular maars (steam explosion craters). Maars are believed to originate from a combination of explosion caused by groundwater coming into contact with hot lava or magma and subsequent collapse. The maars of El Pinacate are rivalled only by similar formations in Africa. The largest single maar is El Elegante, formed 32,000 years ago, which is 1,400 meters (4,600 feet) from rim to rim and 140 meters (460 feet) deep. It takes visitors a two to three-hour hike to reach its rim and be rewarded by a spectacular view.

The volcanic forms of El Pinacate are relatively recent in geological terms, most having been formed during the Quaternary Period, which began some 2.8 million years ago. The most recent volcanic activity in this area was only about 11,000 years ago. Some volcanologists believe that some of these craters could become active again in the future, with the potential to form volcanoes up to a few hundred meters in height.

Ron Mader, the founder of Planeta.com and a foremost authority on responsible tourism in Mexico, has marveled at the “bizarre and mind-boggling scenery” of El Pinacate., which so resemble the lunar landscape that between 1865 and 1970 it was used by NASA as a training ground for astronauts preparing for the moon landings. The lava field is so vast and sharply defined that it later turned out that the astronauts could easily recognize it from space!

Sand dunes (Gran Desierto de Altar)

The western and southern parts of the El Pinacate and Gran Desierto de Altar Biosphere Reserve have entirely different scenery. The Gran Desierto de Altar is North America’s largest field of active sand dunes (erg). Several types of dunes are represented here, the tallest reaching 200 meters in height.

The sand needed to form and maintain these dunes comes from the fluvial and deltaic sediments of the Colorado River delta (to the west), the beaches of the Sea of Cortés/Gulf of California (to the south), the River Sonoyta (to the east) and the smaller river and stream fans formed in those parts of the reserve where there are volcanic and granitic mountains.

Sand dunes of Gran Desierto de Altar

Sand dunes of Gran Desierto de Altar

Prior to the opening of the Sea of Cortés (Gulf of California), vast amounts of sediment accumulated in this region brought by rivers of which little trace remains today. The creation of the Sea of Cortés, 5.3 million years ago, shortened the rivers and increased their average gradient (rejuvenation), causing them to cut into the pre-existing landscape leaving behind river terraces, remnants of the former higher level floodplains.

The fields of sand dunes of the Gran Desierto de Altar cover more than 550,000 hectares (5700 sq.km.) Several different kinds of sand dunes are found here–linear, crescent-shaped (barchans) and star-shaped–and they can be simple, compound or complex, depending on seasonal changes in the direction and strength of the wind.

Although linear dunes dominate (70%), crescent-shaped complex dunes and star-shaped dunes are of more interest because they exist in only a few locations in the world. Spectacular and very large star-shaped dunes, up to 200 meters high, occur both singly and in long ridges up to 48km in length. Star-shaped dunes possibly evolved from crescent dunes which changed their direction of movement becoming “reversing dunes”. Side winds may account for the multiple arms of some star-shaped dunes.

Other features – Granite massifs

In addition, there are several granite massifs (inselbergs), such as the Sierra del Rosario, emerging like islands from the sandy desert flats and dunes. They range in elevation from 300 to 650 meters above sea level. They represent another remarkable landscape feature harboring distinct plant and wildlife communities.

Mexico’s latest UNESCO World Heritage Site is the El Pinacate and Gran Desierto de Altar Biosphere Reserve in Sonora, added to the UNESCO list in June 2013. Mexico now has 32 World Heritage Sites.

The El Pinacate and Gran Desierto de Altar Biosphere Reserve is part of the Sonoran desert, which extends from Sonora into the northern part of Baja California, and across the U.S. border into Arizona and California. The reserve covers 714,566 hectares with an additional 354,871 hectares of buffer zone. It is a relatively undisturbed portion of the Sonoran desert, and offers visitors a dramatic combination of two very distinct landscape types: volcanic landscapes (El Pinacate) and sand dunes (Gran Desierto de Altar).

pinacate-map-googleThe biosphere reserve is immediately south of the U.S. border, west of the Lukeville (Arizona) – Sonoyta (Sonora) border crossing, and 50 km (30 miles) north of the fishing and tourist town of Puerto Peñasco. The San Luis Río Colorado–Sonoyta section of Mexican federal highway 2 (which runs from Mexicali to Caborca) skirts the northern section of the reserve. Puerto Peñasco is connected to Sonoyta by highway 8. There are entrances to the park from highway 2, 50 km west of Sonoyta, and from highway 8, mid-way between Sonoyta and Puerto Peñasco.

Despite being a desert area, most parts of the biosphere reserve do receive occasional rainfall, which gives this area more biodiversity than is true for most deserts.

El Pinacate and Gran Desierto de Altar Biosphere ReserveVaried scenery

The eastern section of the biosphere reserve, El Pinacate, is a dormant volcanic area of around 200,000 ha (2000 sq. km), centered on the El Pinacate Shield (or Sierra Pinacate) which has lava flows, cinder cones, lava tubes and circular maars (steam explosion craters). Ron Mader, the founder of Planeta.com and a foremost authority on responsible tourism in Mexico, has marveled at the “bizarre and mind-boggling scenery” of El Pinacate. The geology and landforms of this area so resemble the lunar landscape that between 1865 and 1970 NASA used it as a training ground for astronauts preparing for the moon landings. The lava field is so vast and sharply defined that it later turned out that the astronauts could easily recognize it from space!

The western and southern parts of the El Pinacate and Gran Desierto de Altar Biosphere Reserve are entirely different. The Gran Desierto de Altar is North America’s largest field of active sand dunes (erg), more than 550,000 hectares (5700 sq.km.) in area. Several types of dunes are represented here, the tallest reaching 200 meters in height, including linear, crescent-shaped (barchans) and star-shaped dunes.

Flora and Fauna

The highly diverse mosaic of habitats in the biosphere reserve is home to complex communities and a surprisingly high species diversity. More than 540 species of vascular plants, 44 mammals, more than 200 birds and over 40 reptiles inhabit this seemingly inhospitable desert. All feature sophisticated physiological and behavioural adaptations to the extreme environmental conditions. Insect diversity is high, though not fully documented. Several endemic species of plants and animals exist, including two freshwater fish species.

The flora in Sierra Pinacate includes the sculptural elephant tree (Bursera microphylla). The name “Pinacate” derives from pinacatl, the Nahuatl word for the endemic desert stink beetle. The biosphere reserve has large caves inhabited by the migratory lesser long-nosed bat (Leptonycteris curasoae yerbabuenae), which is an important pollinator and seed dispersal vector, and the endangered fish-eating bat (Myotis vivesi); both species are endemic.

Other noteworthy species in the reserve include the threatened Sonoran pronghorn (Antilocapra americana sonorensis), an endemic subspecies of restricted habitat and the fastest land mammal in North America; bighorn sheep (Ovis canadensis mexicana), the mule deer (Odocoileus hemionus) and gray fox (Urocyon cinereoargenteus), the Gila monster (Heloderma suspectum) and desert tortoise (Gopherus agassizii).

Human occupation and use

El Pinacate and Gran Desierto de Altar contains numerous archaeological remains, some dating back more than 20,000 years. It is an important cultural site for the indigenous Tohono O’odham people who consider El Pinacate peak, where they still perform sacred ceremonies, as the place where  creation occurred.

Management issues

The El Pinacate section of the biosphere reserve was first designated a “protected area” in 1979. In 1993, it was a declared a Biosphere Reserve, along with the Gran Desierto de Altar, by then president Carlos Salinas de Gortari. The biosphere reserve is managed by Mexico’s National Commission of Natural Protected Areas (Conanp), in collaboration with the Sonora state government and the Tohono O’odham people.

The number of people visiting the reserve has risen rapidly from fewer than 6,000 in 2000 to more than 17,500 in 2010. The two major challenges that management needs to take into account are how to ensure that indigenous views about the reserve’s use are respected, and how to limit negative impacts on the reserve from nearby tourism developments.

The potential negative impacts include:

  • increased vehicle traffic, resulting in ecological disturbance, littering and wildlife road kills.
  • pressure to extend the limited existing road infrastructure by adding new roads, though this might lead to more exotic (alien) invasive species.
  • increased habitat damage from the growing use of off-road vehicles

UNESCO considers that, “The most critical long term management issue is to address potential problems derived from tourism-related water consumption.”

Given that this reserve is on the Mexico-U.S. border, transboundary cooperation is essential, and UNESCO actually recommends that the best way forward is to establish a Transboundary Protected Area, extending into Arizona.

The combination of a volcanic shield with spectacular craters and lava flows, almost entirely surrounded by an immense sea of dunes, makes this an area of great scientific interest, and an ideal laboratory for researchers interested in geology and geomorphology.

New Durango-Mazatlán highway officially open

President Enrique Peña Nieto has officially opened the new Durango-Mazatlán highway which has taken more than a decade to complete. He inaugurated the new highway early today (17 October), Mexico’s annual “Road Workers’ Day” (“Día del Caminero”).

The new 1.2-billion-dollar, partly 4-lane, 230-kilometer highway will slash the time taken to drive from the city of Durango to the Pacific coast resort of Mazatlán, from 5 hours to about 3 hours. It is by far the single most important and complex road project in Mexico in recent years.

Mexico's major highways (Fig 17-3 of Geo-Mexico, the geography and dynamics of modern Mexico).

Mexico’s major highways (Fig 17-3 of Geo-Mexico, the geography and dynamics of modern Mexico). All rights reserved.

The most spectacular part of the highway is the Baluarte Bridge (Puente Baluarte), the tallest cable-stayed bridge in the world, which straddles the border between the states of Sinaloa and Durango and circumvents the need to negotiate the twisting and dangerous route taken by the old highway through the Espinazo del Diablo (Devil’s Spine). The Baluarte Bridge is a 1,124-meter-long bridge that rises almost 400 meters above the river below. The highway also includes 63 tunnels, the longest of which (El Sinaloense) is 2800 meters in length.

Durango-Mazatlan highwayThe firms involved in constructing the highway included Omega Corp, Tradeco Industrial, FCC Construcción, La Peninsular Compañía Constructora, Grupo Mexicano de Desarrollo and Grupo Hermes.

The highway has four toll booths; car drivers will pay about $500 pesos in total for a one-way trip along the entire length of the new highway. The highway is expected to carry 3,000 vehicles a day during its first year of operation, a figure expected to rise to 6,000 vehicles a day within the next six years.

Note: We are still waiting for a first-hand report from anyone who has driven the new highway. While the highway has been officially opened, at least one section of the highway is not yet open to regular traffic because of on-going repairs due to damage sustained during last month’s storms.

The urban regeneration of Barrio Antiguo in Monterrey

 Updates to Geo-Mexico  Comments Off on The urban regeneration of Barrio Antiguo in Monterrey
Oct 142013
 

The city of Monterrey in Nuevo León has begun an urban regeneration scheme to rejuvenate one of its oldest sections, Barrio Antiguo (see map below).

Location of Barrio Antiguo, Monterrey.

Location of Barrio Antiguo, Monterrey. (Base: Google maps)

Barrio Antiguo is the area to the east of the Macroplaza. It is bounded to the south and east by Avenida Constitución, to the west by Calle Doctor Coss and to the north by Calle Padre Mier.

Earlier this year, city authorities, with assistance from the Nuevo León state government, published an online Catalog of Buildings of Historic and Artistic Importance in Barro Antiguo, which will form a basis for future planning decisions about any changes of land use in the area. [To view the entire catalog, scroll down in the center frame on that page.]

The Catalog includes a series of historic maps, from 1765, 1791, 1846, 1865, 1922, 1933 and 1947 respectively, as well as modern maps showing the location of all individual properties in Barrio Antiguo, color-coded to show their importance in terms of conservation and restoration efforts.

Conservation value of buildings in Barrio Antiguo, Monterrey

The first phase of the urban regeneration scheme (called “Nuevo Barrio Antiguo”) includes a “paint job” in which all the buildings in the Barrio’s 16 blocks (manzanas) will be repainted in pastel colors. Owners can choose from a palette of pastel colors that has been predetermined as being in keeping with the historic and architectural characteristics of the area. Click here for the approved colors, complete with color swatches, and the matching paint names for different manufacturers.

During the first phase, new street signs will be installed, as well as tiles highlighting associations to famous people who lived or worked in the Barrio Antiguo. A second phase will restore sidewalks, add new street lighting, and involve public consultation about creating cultural and recreational space. Some streets would also be pedestrianized. Planners would seek to ensure that a wide mix of land uses is retained in the area, including residential, and that the area becomes attractive to visitors and tourists. The accessibility of Barrio Antiguo would be boosted if (or when) Line 3 of the city’s Metro system is built, since its proposed route would start near Barrio Antiguo and run 7.5 kilometers to the Metropolitan Hospital.

Barrio Antiguo, Monterrey

Barrio Antiguo, Monterrey

The Catalog identifies 193 buildings from the 18th, 19th and 20th centuries as being worth preserving, and the catalog entries for individual buildings provide a cross-reference to other listings of historic buildings such as those previously compiled by the National Anthropology and History Institute (INAH) and state-level agencies. The oldest building in Barrio Antiguo apparently dates back to 1765, while La Casa del Campesino incorporates parts of an even earlier building (from 1728). The listed buildings cover a range of architectural styles ranging from what is described as “vernacular north-eastern architecture” to neoclassic and art deco.

As Monterrey has grown, the condition of Barrio Antiguo’s building stock has deteriorated significantly. During the 1990s and 2000s, many buildings were turned into twilight zone businesses such as cafes, bars and nightclubs. La Casa del Campesino has been repeatedly re-purposed over the years, serving at different times as a government building, charity, hospital, and even a short-term emergency shelter following severe floods in 1909.

Not everyone is happy about the regeneration plans. Critics are vocal about the potential interruption to commerce and small businesses, and fear that it will attract land speculators.

In addition, this is not the first time that plans have been hatched to regenerate Barrio Antiguo. Grandiose plans have been announced on several previous occasions but have never come to fruition.

Plan for open-pit gold mine in Baja California Sur rejected

 Books and resources, Mexico's geography in the Press  Comments Off on Plan for open-pit gold mine in Baja California Sur rejected
Oct 122013
 

In November 2012, the federal Environment and Natural Resources Secretariat (Secretaría de Medio Ambiente y Recursos Naturales, Semarnat) refused a request to allow open-pit (opencast) mining in the buffer zone of the Sierra La Laguna Biosphere Reserve in Baja California Sur.

The request came from Zapal SA de CV, whose mining project, currently named “Los Cardones”, is located about 60 km from La Paz, the state capital. The proejct is close to the small settlements of El Triunfo, San Antonio and El Rosario. This mining project was previously called “Paredones Amarillos” and “La Concordia”. The original Concordia project, proposed by US mining firm Vista Gold and Toronto-listed Argonaut, was opposed on environmental and public health grounds by several environmental groups including the Mexican Center for Environmental Law (CEMDA).

Location of Los Cardones mining project.

The latest version, Los Cardones, was resubmitted to authorities in September 2012. The project involved 423 hectares of semi-arid scrub-land, from which Zapal hoped to extract 40 metric tons of gold in the next decade using open-cast (pit) mining. The $217-million project would have created around 2200 jobs.

According to the project’s website (no longer functional), the mining project would have relied entirely on desalinated seawater (brought to the site by a 40-km aqueduct), which would be continuously recycled, and would therefore have no impact on local aquifers. Zapal claimed that the mine would have been the first gold mine in Mexico to use a closed-system cyanidation process, designed to prevent any contamination of the local environment. Zapal is part of the Invecture group which already operates an open cast copper mine in Piedras Verdes, Sonora, claimed to have an impeccable environmental and safety record.

Semarnat rejected the proposal on the grounds that it did not meet the legal requirements for mining operations in a Biosphere Reserve buffer zone. It is likely that a revised application will be made in due course. However, officials of the Baja California state government have previously gone on record as saying that they will oppose any open-cast mining in the state, because of its potential environmental impacts.

Anti-mining protests elsewhere in Mexico

David Bacon, author of “The Right to Stay Home: How US Policy Drives Mexican Migration”, wrote an informed account for the American Program website of several cases across Mexico where opposition to Canadian mining firms has arisen.

  • Mexican Farmers Up Against Canadian Mining Goliaths

A Guardian photo essay entitled “Mexico mining: ‘When injustice is law, resistance is duty’ – in pictures” reported on a January 2013 meeting of some 500 activists from across Mexico and Central America in Capulálpam de Méndez, Oaxaca. The meeting’s slogan was,  “Si la vida! No la
minera!” (Yes to life! No to mining!). It was held to co-ordinate local resistance to the human and environmental costs of mining on the region’s communities.

Why is northern Mexico a desert region?

 Excerpts from Geo-Mexico  Comments Off on Why is northern Mexico a desert region?
Oct 102013
 

Much of northern Mexico experiences either an arid (desert) climate (less than 250 mm [10 in] of rain/year) or a semiarid (semi-desert) climate (250–750 mm [10–30 in] of rain/year). Areas with an arid (desert) climate (see map) include most of Baja California and western Sonora (together comprising the Sonoran desert), as well as the northern section of the Central Plateau (the Chihuahuan desert). These areas can experience frost and freezing during the winter.

Major climate regions in Mexico. (Fig 4-5 of Geo-Mexico, the geography and dynamics of modern Mexico). All rights reserved.

Areas of semiarid (dry steppe) climate include most of the Central Plateau as well as western sections of the Western Sierra Madre, northern Yucatán and scattered inland areas as far south as Oaxaca. The rains in this region fall mostly in the summer, and localized heavy thunderstorms are quite common. The southern parts of this climatic region are warmer than the northern parts. (Mexico’s seven climate regions)

Why do parts of northern Mexico receive very little precipitation, making them deserts?

The major reason is that the zone between the Tropic of Cancer (latitude 23.5 degrees N) and latitude 30 degrees N is influenced by the Hadley Cell. This is the name given to the atmospheric circulation in tropical regions, named after George Hadley, the English amateur meteorologist who first proposed its existence, in 1735.

The Hadley Cell

The functioning of the Hadley Cell

The Hadley Cell is the driving force behind many aspects of Mexico’s weather and climate. How does it operate? Solar heating is at a maximum near the equator and diminishes towards the poles. The area near the equator is the Intertropical Convergence Zone or ITCZ (see diagram). The heating of the ITCZ makes the air there rise, leaving an area of low pressure on the surface. This low pressure sucks in air along the earth’s surface from the subtropical high pressure areas about 30 degrees N and S of the equator creating the trade winds. The trade winds pick up moisture and latent heat over the oceans before converging from either side of the equator in the ITCZ. As the air in the ITCZ rises vertically, its water vapor condenses and rain falls from the towering convective clouds. This is the ascending limb of the Hadley cell. At a height of 10–15 km above the surface, the air, now minus its moisture, returns polewards as high level anti-trade winds. Sunbathers on Mexican beaches who notice two sets of clouds above them at different heights traveling in opposite directions are witnessing the trade winds and anti-trade winds in action.

In the subtropics, this air then descends again towards the surface to complete the cell and initiates the surface trade winds again. The descending air warms up as it sinks; its relative humidity decreases, and so no precipitation occurs; hence these high pressure subtropical areas are arid. Mexico’s arid and semiarid areas coincide with the descending air segment of the Hadley Cell and these high pressure subtropical areas.

In addition, the climate of the west coast of the Baja California Peninsula is influenced by the cool Californian current, which flows towards the south. The relative humidity of the air above it drops as the current enters warmer waters, so it is not likely to bring rain to the peninsula.

The aridity of the Sonoran desert is also partly due to its position in the rain shadow of the Western Sierra Madre. The Chihuahuan desert is in an even more marked rain shadow, protected by both the Western Sierra Madre and the Eastern Sierra Madre.

Stunning stream patterns in northern Baja California

Photographer Adriana Franco from Querétaro has taken several truly stunning artistic images of stream patterns in the semi-arid region of northern Baja California (near Mexicali). The photos, taken from an ultralight, show the details of the dendritic (= tree-like) stream patterns in this region. Dendritic stream patterns are common worldwide, but these images are exceptional. In general, dendritic stream patterns are associated with relatively gentle gradients where the underlying rocks are similar throughout the drainage basin.

Are Aztec chinampas a good model for food production and agro-development?

 Other  Comments Off on Are Aztec chinampas a good model for food production and agro-development?
Oct 072013
 

There is no doubt that Mexico’s indigenous farmers developed numerous ways to ensure successful harvests. The details varied from one region to another, but among the techniques employed were:

  • the mitigation of erosion by building earth banks and check dams in gullies
  • polyculture, recognizing that this minimized the risks inherent in monoculture.
  • the terracing of steep slopes to channel water where it was most needed.

In addition, some indigenous groups, including the Aztec in central Mexico, took advantage of their expertise in water management to develop highly productive systems of farming in wetlands. The chinampas (or so-called ‘floating gardens’) in the Valley of Mexico are the prime example of this water management skill, though similar systems were also used in the coastal marshes along the Gulf coast.

On the other hand, the later introduction of large-scale commercial farming methods has often led to deleterious impacts on the countryside and the long term sustainability of such methods is questionable.

In seeking to help Mexico’s rural areas, some development experts have suggested re-adopting Aztec methods, especially their method of building chinampas to farm wetlands. The invention of chinampas as a highly productive form of intensive wetland cultivation was, historically, one of the greatest ever agricultural advances in the Americas. Among other things, it allowed settlements to thrive in areas where rain (and therefore rain-fed food production) was markedly seasonal.

Among attempts to re-introduce ancient methods, one which stands out occurred in the 1970s and 1980s, when INIREB (Instituto Nacional de Investigaciones sobre Recursos Bióticos), based in Xalapa (Veracruz) employed chinamperos from the Valley of Mexico to build experimental chinampa-like fields in Veracruz and Tabasco . These projects are briefly described in Andrew Sluyter’s fascinating book Colonialism and Landscape, Postcolonial theory and applications (Rowman and Littlefield, 2002), the main basis for this summary.

Google Earth image of camellones chontales

The most ambitious project was a later federally-organized one in Tabasco, where 65 massive platforms (camellones), each about 30 meters wide and from 100 to 300 meters long, were built in the swampy Chontalpa wetlands. The project, known as camellones chontales was backed by the local Chontal community though it was not directly involved in the construction phase. Because of the scale of the project, large mechanical dredgers were used to build the platforms, rather than relying on laborious and slower hand labor.

After construction, the Chontal community began farming the platforms, but initial results were very disappointing. Things improved with time, especially when the Chontal took full control of the project. From their perspective, the project meant that more members of the community now had land that could be farmed, and they shifted the emphasis away from the “vegetable market production” favored by officials towards growing corn (maize), beans and bananas for local household consumption, improving local food availability.

Recent press reports, such as this 2-minute Youtube clip (Spanish), claim that many parts of the camellones chantales have now been abandoned, owing to insufficient investment in maintenance.

Why did the project fail initially?

This is one of the key questions connected to this example. Sluyter refers to two articles written by Mac Chapin (from Cultural Survival, an organization that champions the rights of native peoples). Chapin argues that the projects, and their assumptions, were fundamentally flawed. For example, the use of dredges to construct the platforms turned the soil profile upside down, bringing infertile clay towards the top and sending nutrient-rich layers downwards, beneath the reach of plant roots. In turn, this meant that organic matter and fertilizers had to be added to the land in order for good crop yields. Because of the dredging, the canal floor between the platforms was very irregular, making it much more difficult for the Chontal to fish using drag nets. Many of the crops planted were “exotic” and production was market-oriented rather than subsistence or locally-oriented. Chapin was particularly critical of the lack of suitable transport routes for sending produce to distant markets. In addition, chemicals were needed because of the proliferation of insects in these lowland wetlands. (Insects are rarely a problem at the higher altitudes of central Mexico).

Chapin concluded that this development project was just one more in a long line of failures where an outside model was introduced into a new area without sufficient prior research or local involvement in the planning stages. Sluyter agrees with this conclusion, pointing out that there is no evidence that these Tabasco wetlands ever had any form of chinampa farming, even in pre-Columbian times, perhaps because they have “a much greater annual fluctuation in water level than those in Campeche and Veracruz”.

“Los que llegaron”, Spanish language videos about Mexico’s immigrant groups

 Books and resources, Teaching ideas  Comments Off on “Los que llegaron”, Spanish language videos about Mexico’s immigrant groups
Oct 052013
 

Once TV México (“Eleven TV Mexico”) is an educational TV network owned by the National Polytechnic Institute (Instituto Politecnico Nacional) in Mexico City. Over the years, Once TV México programs have won numerous national and international awards.

Many of its programs are available as webcasts or on Youtube. Once TV México has made hundreds of programs that provide valuable resources for Spanish-language geography classes or for students of Spanish or anyone wanting to improve their Spanish-language skills. For example, their long-running program “Aquí nos tocó vivir” (“Here We Live”) has explored all manner of places throughout Mexico over the past 35 years, and has received UNESCO recognition for its excellence.

Of particular interest to us is “Los que llegaron” (“Those Who Arrived”), a series of programs looking at different immigrant groups in Mexico. Each 20-25 minute program focuses on a different group and explores the history of their migration to Mexico, their adaptation to Mexican life, their integration into society, the areas where they chose to settle, and the links between their home countries and Mexico.

Mexico has a long history of welcoming people from other countries, including political refugees. Each of these programs offers some fascinating insights into the challenges faced by migrants arriving in Mexico for the first time.

Sister city of Segusino, Italy

Sister city of Segusino, Italy

For instance, the program about Italian immigration to Mexico (above), explains why Mexico was seeking colonizers in the middle of the 19th century in order to populate and develop rural areas. One group of Italians settled in Veracruz (in present-day Gutiérrez Zamora); another group, 3,000 strong, and from the Veneto region in northern Italy, settled in Chipilo, near the city of Puebla. (For anyone not familiar with Chipilo, one of our favorite bloggers, Daniel Hernandez, has penned this short but memorable description of a typical Sunday morning there: Cruising in Chipilo, an Italian village in Mexico).

Italian immigration increased dramatically after the 1914-1918 war. Today, according to the program, there are approximately 13,000 Italian citizens residing in Mexico and an estimated 85,000 Mexicans of Italian descent. Note, though, that most sources quote a much higher figure for the latter category, perhaps as high as 450,000.

[Aside: In chapter 4 of “Mexican National Identity, Memory, Innuendo and Popular Culture”, William H. Beezley looks at the role of itinerant puppet theater in molding Mexico’s national identity. The largest and most famous single troupe of all was the Rosete Aranda troupe, formed by two Italian immigrants in 1850. The troupes went from strength to strength in the next half-century. By 1880, the Rosete Aranda company had 1,300 marionettes and by 1900 a staggering 5,104. Their annual tours around the country helped influence national opinions and attitudes.]

Program list for the “Los que llegaron” series:

  • Españoles (Spaniards)
  • Alemanes (Germans)
  • Húngaros (Hungarians)
  • Italianos (Italians)
  • Argentinos (Argentines)
  • Ingleses (English)

Geotourism in Mexico: García Caves (Grutas de García) in Nuevo León

 Other  Comments Off on Geotourism in Mexico: García Caves (Grutas de García) in Nuevo León
Oct 032013
 

The Garcia Caves (Grutas de García) are located in the Cumbres de Monterrey National Park, 9 km from the small town of Villa de García, and about 30 km from the city of Monterrey (state capital of Nuevo León). The highest point in the park is Copete de las Águilas which rises to 2260 m (7,410 ft) above sea level, but its best known peak is Saddle Hill (Cerro de la Silla), the distinctive saddle-shaped hill that overlooks the city.

Much of the park, including the mountains, are composed of sedimentary rocks that were originally laid down as marine sediments and then subsequently folded, uplifted and exposed to erosion. The extensive areas of limestone in the park, which date from the Cretaceous period, have been subject to karstification over 50 to 60 million years, which has resulted in typical karst landforms such as sinkholes, caves, cave formations and underground streams.

The Garcia Caves, one of the largest cave systems in Mexico, are deep inside the imposing Cerro del Fraile, a mountain whose summit rises to an elevation of 1080 meters above sea level, more than 700 meters above the main access road. The entrance to the caves is usually accessed via a short ride on a 625-meter cable car that was built to replace a funicular railway.

The cave system was first reported in 1843 by the Marmolejo family who informed their local prist Juan Antonio Sobrevilla that they had stumbled across it while looking for firewood.

Guided tours of the cave system show visitors some of its 27 separate chambers along a 2.5-kilometer (1.6 mile) route. The full system extends more than a kilometer further into the mountain reaching depths of more than 100 meters (340 feet) beneath the surface. The limestone of the cave walls contains lots of marine fossils. The caves have extensive and impressive formations of dripstone, including stalactities, stalagmites and other forms.

Unlike the suffocating heat of the Naica Crystal Caves in Chihuahua, the cave temperature here remains about 18̊C (65̊F) all year.

The chambers and formations have been given whimsical and imaginative names such as

  • “El salón de la luz” (The Light Chamber) where the natural translucence of the ceiling rock allows light from the outside to filter through.
  • “La octava maravilla” (The Eighth Wonder), a natural column formed where a stalagmite growing from the floor joined a stalactite, growing from the ceiling
  • “El mirador de la mano”, a stalagmite shaped like a human hand.
  • “El Nacimiento” (The Nativity),
  • “La Fuente Congelada” (The Frozen Fountain),
  • “La Torre China” (The Chinese Tower),
  • “El teatro” (The Theatre), and
  • “El Árbol de Navidad” (The Christmas Tree).

Sep 302013
 

This post describes some of the many online resources about chinampas, one of Mexico’s ancient and most important indigenous forms of sustainable agriculture.

For photos, the best starting point is Dr. Jason Turner’s site about chinampas which includes an extensive bibliography about chinampas as well as several “Virtual Field Trips” (photo sequences). Even though these photo sequences often lack any accompanying descriptions or captions, they cover a wide range of ideas, and are organized in self-explanatory groups such as:

For an article describing a recent tour of a working chinampa in Xochimilco’s Ecological Reserve. illustrated with great photos, try Touring Xochimilco’s farms with De la Chinampa written by Lesley Téllez (self-described food writer with a “deep love for Mexican food and culture”) on her blog “The  Mija Chronicles”.

Youtube also has a variety of chinampa-related resources. In English, the best introduction is Discovery Atlas – Mexico: Xochimilco which provides a good background to the history and covers the basics.

Two Spanish-language Youtube resources provide valuable additional information. Each video lasts about 5 minutes, but neither video has English language subtitles.

The first is Divina Ciudad: De la chinampa a la mesa which looks at one specific project designed to help raise public awareness and aid the conservation of the remaining chinampas in Xochimilco, on the south-eastern outskirts of Mexico City. This project supplies consumers with fresh produce grown on the chinampas in Xochimilco or sourced from within 150 km. See the project’s website – De La Chinampa – for more information.

The second Spanish language video is Profeco TV Reporte Especial: Productos de la Chinampa, un ejemplo de consumo sustentable, This video, made by the federal consumer protection agency Profeco, explains how the produce grown on the chinampas is pesticide-free and relies on sustainable production methods. It calls on viewers to “learn more about the method and help ensure that chinampas do not disappear.”

Goldcorp’s Los Filos mine in Guerrero: mega-mine or mega-disaster?

 Mexico's geography in the Press  Comments Off on Goldcorp’s Los Filos mine in Guerrero: mega-mine or mega-disaster?
Sep 282013
 

Canadian firm Goldcorp is the largest gold miner in Mexico, with mining concessions covering more than 40,000 hectares. Since 2008, it has been actively developing the mine of Los Filos, in the municipality of Eduardo Neri, which could become Latin America’s largest gold mine.

Los Filos is in Guerrero’s “Gold Belt” that runs from Mezcala to Argelia. The open-cast mine at Los Filos is midway between Mezcala and El Carrizalillo, some 50 km from the state capital Chilpancingo. The mining project will employ 800 workers and double the population of El Carrizalillo. The rocks here contain between 0.5 and 0.8 grams of gold per ton of ore. Los Filos is expected to yield 60 million metric tons of gold ore over the next 20 years, as well as some ancillary silver, lead and zinc. The mining operation will require investments of $1 billion over the mine’s anticipated 20-30 year lifetime.

The Los Filos project is actively opposed by several environmental groups, including The Mexican Network of People Affected by Mining (La Red Mexicana de Afectados por la Minería, REMA), a network of communities, movements, organization, groups and individuals “affected by, and concerned about, the socio-economic impacts of mining in Mexico”.

REMA has joined the campaign to force Canadian mining firm Goldcorp to halt work at Los Filos. REMA supports the recently created  Mesoamerican Movement Against the Extractive Mining Model, which claims that the existing extractive mining model has proven to be “highly predatory”, and has “significantly increased extraction, causing destruction of territory, seriously affecting natural resources, and irreversibly damaging the health of Mexican citizens”. It is especially concerned that hundreds of tons of cyanide have already been used in Mexico to process gold ore, contaminating water reserves.

REMA cites Goldcorp’s “Los Filos” mining project in Guerrero as a point of particular concern and an example of what is happening throughout the country. REMA claims that there is inadequate regulation and environmental monitoring and that the project is “causing division of communities, disease and death from the chemicals used and environmental damage through drainage of acids and polluting dusts”.

Another Goldcorp mining proposal, at Alto Lucero in the state of Veracruz, also met with substantial opposition from local residents and environmental groups. More information about the amounts of cyanide believed to be used in mines throughout Latin America, including Goldcorp projects, was available via a Map of Cyanide in Latin America (Mapa del Cianuro en América Latina) at http://www.conflictosmineros.net/biblioteca/campana-contra-el-uso-de-cianuro/mapa-del-cianuro-en-america-latina/download [Sep 2013]

Will Los Filos turn out to be a mega-mine or a mega-disaster? Only time will tell.

In 2012, the Mexican Institute for Competitiveness (Instituto Mexicano para la Competitividad AC, IMCO) published an analysis of the competitiveness of 77 of the largest cities in Mexico, looking to see which of them offered balanced growth alongside a good quality of life for their inhabitants.

portada_indiceThe elements of competitiveness considered included the degree of compactness (more compact cities are more efficient and sustainable), public finances, transport, security, water management and waste management. The IMCO methodology is explained in detail in the report Índice de Competitividad Urbana 2012. In short, IMCO evaluated each of the 364 municipalities involved in the 77 cities, using 60 indicators grouped into 10 mutually-exclusive sub-indexes.

Between them, these 77 cities house 63% of Mexico’s total population and account for 80% of Mexico’s GDP. 55% of Mexico’s population live in cities managed by two or more municipalities. IMCO found that public transport was adequately coordinated in only 13% of cities with two or more municipalities, while urban planning was coordinated in 35% of the multi-municipality cities.

The IMCO report concludes than most Mexican cities do NOT offer balanced growth and a decent quality of life for residents. Individual cities can be compared using this IMCO site.

The only city offering a “High” level of competitiveness was Monterrey.

Several cities offered an “Adequate” level: Mexico City, San Luis Potosí, Querétaro, Ciudad del Carmen, Saltillo, Tampico, Colima, Guadalajara, Mexicali, Monclova and Campeche.

At the other end of the spectrum, the competitiveness of several cities in Mexico was categorized as “Low”: La Piedad, Cd. Cárdenas, Rioverde, Matamoros, Tehuantepec, Tijuana, San Francisco del Rincón, Cd. Juárez, Ensenada and Poza Rica.

The lowest levels of competitiveness (“Very Low”) among the 77 cities studied were found in two cities in the state of Guerrero: Chilpancingo and Acapulco.

The report used data from 2010, so some aspects of these cities will have changed since that date. For example, the sharply increased murder rate in Monterrey since 2010 will have reduced its lead over other cities.

Certain cities have faced severe challenges of rapid growth. In recent decades, the cities that have grown most rapidly have not been the very large cities like Monterrey, but mid-sized cities. One example of a mid-sized city that has grown rapidly is Ciudad Juárez, whose area grew 497% from 1980 to 2009, while its population rose 70%. This rapid growth may have contributed to the high levels of crime experienced in the city.

IMCO concludes that Mexican cities are showing clear signs of not functioning well: chaotic expansion, heavey traffic, high levels of air pollution, poor supply and/or quality of potable water, high crime levels. These have caused cities to lose competitiveness and the capacity to attract human talent from outside, whether for business, sports or research.

The single obstacles to increased competitiveness are the lack of professional urban management, and the fact that many cities involve two or more municipalities. The laws governing municipal elections inevitably mean that administrations are short-term, with a high level of staff turnover. The impossibility of re-election means that many urban projects are overly superficial and they lack continuity from one administration to the next.

IMCO suggests that a new administrative position be created: the city manager (administrador urbano). The city manager would be a professional manager, and would ensure that the city has adequate coordination for all urban public services, even where more than one municipality is involved. This would free the municipal politicians from having to tackle the day-to-day management issues of the city and allow them more time to engage productively with the citizenry. However, for this to happen, a major institutional innovation is required.

Silver working in Mexico

The center of Mexico’s silver craftsmen and silver making industry is the city of Taxco, in the state of Guerrero. Several pre-colonial groups had developed the technical skills needed to fashion elaborate and complex silver items, especially jewelry, but knowledge of these techniques had largely died out by the start of the 20th century. Somewhat surprisingly, the silver-making industry was reignited in Taxco by an American, William Spratling.

Spratling (1900-1967) was an American-born silversmith and artist, best remembered today for having reinvigorated 20th century Mexican silver design. Spratling started a small silver industry in the picturesque town of Taxco in the state of Guerrero in 1931, with the intention of benefiting local people. Taxco was one of the earliest silver-mining areas exploited during colonial times. Local silver mines were still important in Spratling’s day, but have since closed, with silver brought in to Taxco from elsewhere in Mexico.

William Spratling’s designes were based on pre-colonial motifs and he trained local craftsmen to produce them in his workshop Taller de las Delicias. He gained a reputation for fine designs and excellent workmanship. Many of his apprentices went on to found their own silver workshops. Silver working became very popular in Taxco and the town gradually transformed itself into Mexico’s premier showcase for high quality silver work of all kinds, from jewelry to tableware. Over the years, the town attracted shoppers and has also become a very important tourist destination.

Sometimes called the “Father of Mexican Silver”, Spratling not only sold silver locally in Taxco, but also supplied silver items to stores such as Neiman Marcus and Saks Fifth Avenue in New York and elsewhere. Some of his earliest work was inspired by stonework reliefs in nearby archaeological sites such as Xochicalco. The William Spratling Museum near Taxco’s main plaza showcases his personal collection of archeological pieces as well as his original silver-work designs and workshops.

Silver-working exists in many other Mexican towns and cities, but Taxco is the premier place in Mexico for tourists interested in seeing or purchasing fine silver. The town celebrates the National Silver Fair (Feria Nacional de La Plata) in late November each year. The 76th annual Silver Fair runs from Saturday 30 November to Saturday, 7 December 2013.

Many of Spratling’s original designs are still being made today. For example, Spratling Renaissance (which sells silver from Taxco via its online store) proudly proclaims that, “The legacy of William Spratling is the powerful motivator of a collaboration between the last of the generation of Taxco master silversmiths and the rural women artisans of Tecalpulco, a village in the Municipio of Taxco de Alarcón, Guerrero. The jewelry employs old-fashioned jewelry-making arts to fashion ornamental esthetic objects worthy of a museum. Every piece coming from this shop is a perfect reproduction of the unique original masterworks of William Spratling.”

Of several books about Spratling, Sandraline Cederwall’s Spratling Silver stands out. Cederwall is a pre-eminent collectector-dealer of Spratling silver. The latest edition of this work includes an expanded text, many new photographs, and a biographical essay by Barnaby Conrad, a friend and contemporary of the noted silver designer. The book features dramatic black-and-white photographs of silver artworks, underscoring the “intelligent, simple, restrained” yet appealing style that makes Spratling’s designs so collectible.

An innovative aerial public transport system is being proposed in Mexico City as a way to help reduce traffic congestion and increase personal mobility. TUEP (Transporte Urbano Elevado Personalizado), a Mexican start-up, is being supported by the Federal District’s Secretariat for Science, Technology and Innovation (Seciti) and has manufacturing support from vehicle manufacturer DINA.

TUEP says that its system of aerial cabins offers more flexibility than cable cars and will save energy costs and take some vehicles off the roads, reducing emissions. It proposes a series of routes, each 5 to 10 kilometers long, linking densely populated residential areas to the city’s existing Metro and Metrobús networks.

The proposed system is fully automated. The aerial cabins, each seating two adults or an adult with two children, travel along a steel cable and can be diverted on and off the main route into a series of “docking stations” for passengers to alight or disembark. Each cabin is individually controlled by its passengers who select their destination using push button controls. This 2-minute Spanish-language Youtube news clip shows how the system works:

Each 5-kilometer stretch would be able to transport up to 5,700 passengers an hour at full capacity, at an average velocity of 4 m/s (14.4 km/hr). Cabins would travel about 10 meters (30 feet) apart, which should mean short wait times for passengers, who would pay about 6 pesos (less than 50 cents US) per trip.

Constructing the system will require posts placed every 50 meters along the route, with docking stations every 1000 meters or so. The system is being designed to be installed along avenues that currently have a median divide, so that there is minimum disruption to alternative forms of transport. According to its proponents, building TUEP lines would be at least 40% cheaper than adding additional Metrobús routes and only a fraction of the cost of expanding the city’s Metro system.

More details and images of the proposed system are offered in this 4-minute silent video:

TUEP has suggested 18 routes that are worthy of feasibility studies, which include Marina Nacional, Río San Joaquín, Taxqueña-Miguel Ángel de Quevedo, Lázaro Cárdenas, Constituyentes-Santa Fe and Eje 10. If all the proposed routes were built, the TUEP network would have a total length of 135 kilometers, and would have the capacity to handle up to 37 million trips a year.

In this post, we consider the unfortunate plight of the Tohono O’odham people, whose ancestral lands now lie on either side of the Mexico-USA border.

How did this happen?

Following Mexico’s War of Independence (1810-1821), the rush was on to draw an accurate map of all of Mexico’s territory. Mexico’s boundaries following independence were very different to today. At that time, the major flows of migrants linking the USA to Mexico were from the USA to Mexico, the reverse of the direction of more recent flows, where millions of Mexicans have migrated north.

As this map of Mexico in 1824 shows, Mexico’s territory extended well to the north of its present-day limits.

At the end of the Mexican-American War (1846-1848) the 1848 Treaty of Guadalupe Hidalgo ceded over half of Mexico’s territory to the USA. A few years later, under the 1853 Gadsden Purchase (Treaty of La Mesilla), northern portions of Sonora and Chihuahua (shaded brown on the map below) were transferred to the USA.

With minor exceptions since, to take account of changes in the meanders of the Río Bravo (Grande), this established the current border between the two countries.

Impacts on the Tohono O’odham people

One of the immediate impacts of the Gadsden purchase was to split the lands of the Tohono O’odham people into two parts: one in present-day Arizona and the other in the Mexican state of Sonora, divided by the international border. The O’odham who reside in Mexico are often known as Sonoran O’odham.

There are an estimated 25,000 Tohono O’odham living today. Most are in Arizona, but about 1500 live in northern Sonora. In contrast to First Nations (aboriginal) groups living on the USA-Canada border who were allowed dual citizenship, the Tohono O’odham were not granted this right. For decades, this did not really matter, since the two groups of Tohono O’odham kept in regular contact for work, religious ceremonies and festivals, crossing the border when needed without any problem. Stricter border controls introduced in the 1980s, and much tightened since, have greatly reduced the number of Tohono O’odham able to travel freely. This is a particular problem for the Tohono O’odham in Sonora, most of whom were born in Mexico but lack sufficient documentation to acquire a passport.

Since 2001, several attempts have been made in the USA to solve the “one people-two country” problem by granting U.S. citizenship to all registered members of the Tohono O’odham, regardless of their residence. So far, none has succeeded.

The largest community in the Tohono O’odham Nation (the Arizona section of Tohono O’odham lands) is Sells, which functions as the Nation’s capital. The Sonoran O’odham live in nine villages in Mexico, only five of which are offically recognized as O’odham by the Mexican government.

The border between the two areas is relatively unprotected compared to most other parts of the Mexico-USA border.

The Tohono O’odham Nation is often called upon to provide emergency assistance to undocumented workers (and drug traffickers) from south of the border who have underestimated the severe challenges of crossing this section of the harsh Sonora desert. Tribal officials regularly complain about the failure of the U.S. federal government to reimburse their expenses.

ABC News reports (Tohono O’odham Nation’s Harrowing Mexican-Border War) that the border “has made life a daily hell for a tribe of Native Americans” and that drug seizures on the Tohono O’odham Nation’s lands have increased sharply.
