Water Sustainability for Mexico PRESS #RainForAll Water sustainability for Mexico www.islaurbana.org/english PRESS KIT CONTENT WATER CRISIS 1 BENEFITS OF RAINWATER HARVESTING 3 ISLA URBANA PROJECT AND TEAM 5 ISLA URBANA´S RAINWATER HARVESTING SYSTEM 7 OUR PROGRESS 9 RECOGNITION 10 “The amount of rainwater that falls would be enough to guarantee a supply for the entire population.” Antonio Gutiérrez Marco Director of Conagua, Mexico’s Water Authority, 2010. THE WATER CRISIS If we succeed in providing a sustainable solution to Mexico’s water problem, we can accomplish anything. According to the United Nations the world faces a water deficit of 40% by 2030. More than 10 million Mexicans do not have access to water services. The water crisis in Mexico represents one of the major risks in the prosperity and future stability of Mexican citizens. As the situation worsens throughout Mexico, the social injustice in the distribution of this vital source becomes more evident. It’s time to consider true alternatives in creating a new water culture as we continue to be more self-sustaining. If we can provide a sustainable solution to the water problem in Mexico, we can do anything. Women are often in charge of collecting water; putting them In water scarce neighborhoods, families often have to spend in danger when traveling long distances while also keeping time and up to 20% of their income to buy water while them from progressing economically and educationally. municipalities rack up costs subsidizing water trucks in Additionally, they struggle with mental stress and related $ communities where there is no connection to the water grid. health issues from carrying heavy water containers daily. 1 Where cities have exponential growth, pressure THE WATER CRISIS over traditional water sources grows. Mexico City for example, is ranked third on the list of major world cities facing extreme water stress. While nestled in a valley of more than 2,200 meters above sea level, it presents an unusual challenge as well as an amazing opportunity as to how adaptation and ingenuity can provide a permanent solution to a chronic problem. Mexico City is plagued by a profoundly unsustainable system that is depleting its local water reserves while pumping water from further and further distances each time. The Lerma-Cutzamala system which provides 30% of Mexico City’s water, consumes more energy in bringing water from surrounding states than what’s needed to illuminate the entire City of Puebla (Population: 5.8 million). Additionally, the overexploitation of aquifers, where the city supplies 70% of its water, has caused the city to sink 9 meters in the last century. The capital suffers from water shortages in 36% of its homes and each year more houses are subject to cuts in Mexico City before the water supply. However, the crisis in the Valley of Mexico is not due to a genuine lack of water. Every year, torrential rains fall on the city, turning streets into rivers, saturating drains, and flooding entire colonies, a phenomenon that reminds us that the basin was once covered by great lakes. In Mexico City there is a natural abundance of water but it is poorly managed. The main problem is that the city’s relationship with the resource and its natural cycle has been lost. We send rain down our drains while simultaneously seeking to bring water from further and further away. Mexico City after 2 BENEFITS OF RAINWATER HARVESTING Today Tomorrow Future Families gradually increase their rainwater storage and water management capacity until succeeding in reaching complete independence from other unsustainable and expensive water sources. Communities can count on high quality water for a minimum of 6 months during the year and up to 12 months in rural communities. The rainwater harvesting systems work with existing infrasturucture and require little maintenance. 1. Renewable source of clean water 2. Capable of supplying highlands 3.

(CIDAC). 3 BENEFITS OF RAINWATER HARVESTING 4. During the rainy season, it allows the recovery of the city’s aquifers. • It decentralizes the supply of water, that allows for a lower level of dependency and helplessness when there are failures in the traditional city system. 5. Once installed, the systems provide water year after year at very low cost. 6. Rainwater does not need to be transported to the city and to homes artificially, thereby saving emissions and energy. 7. Prevents drains from saturating during downpours, so it reduces floods. There is no future without water 4 ISLA URBANA Isla Urbana is a project with a social and environmental focus founded in 2009 in Mexico City. Our work has concentrated on capturing rainfall in the most efficient and effective way, to allow us to supply rain to water scarce communities. Isla Urbana’s mission is to contribute to the sustainable supply of water in Mexico by driving rainwater harvesting and other practices that allow a rational, ecological and equitable access to water for all. We envision a country where the entire population has sustainable access to water and the overexploitation and excessive discharges of water contaminants become memories of the past. We believe in a resilient, prosperous and sustainable Mexico, with safe water for all. Thanks for being part of that change. #RainForAll www.islaurbana.org/english 5 WHO WE ARE Clara Gaytan OUR FIRST SYSTEM, 2009 In 2009, Isla Urbana installed their first rainwater harvesting system in the house of Mrs Clara Gaytan.

  • Organised Crime and State Sovereignty
    Organised Crime and State Sovereignty The conflict between the Mexican state and drug cartels 2006-2011 Jelena Damnjanovic Honours IV 2011 Department of Government and International Relations The University of Sydney Word Count: 19,373 Student ID: 308171594 This work is substantially my own, and where any part of this work is not my own, I have indicated this by acknowledging the source of that part or those parts of the work. Abstract Since December 2006, the government of Mexico has been embroiled in a battle against numerous criminal organisations seeking to control territory and assure continued flow of revenue through the production and trafficking of drugs. Although this struggle has been well documented in Mexican and international media, it has not received as much scholarly attention due to the difficulties involved with assessing current phenomena. This thesis seeks to play a small part in filling that gap by exploring how and why the drug cartels in Mexico have proved a challenge to Mexico’s domestic sovereignty and the state’s capacity to have monopoly over the use of force, maintain effective and legitimate law enforcement, and to exercise control over its territory. The thesis will explain how the violence, corruption and subversion of the state’s authority have resulted in a shift of the dynamics of power from state agents to criminal organizations in Mexico. It also suggests implications for domestic sovereignty in regions experiencing similar problems with organized crime, perhaps pointing to a wider trend in international

Mexico was the first country to notify the WHO of an outbreak of what later became the first influenza pandemic of the 21st Century, caused by the virus A(H1N1)2009. Before this event Mexico had a national pandemic influenza preparedness plan, which included seasonal influenza vaccination, stockpiles of personal protection equipment and strategic drugs, and risk commu- nication strategies. During the epidemic, the national public health laboratory network and case surveillance systems were strengthened together with surge capacities for intensive care and delivery of antiviral drugs. Risk communication was conducted for people to comply with implemented measures regarding social distancing (workplace and school closures, household quarantine). This report describes the Mexican experience during the 2009 influenza pandemic and the lessons that this experience provides to public health preparedness for future pandemics. (Gac Med Mex.

  • Producing Insecurity: Corn and Markets in Contemporary Mexico
    CORN, MARKETS, AND MOBILIZATION IN MEXICO Erica S. Simmons Assistant Professor of Political Science University of Wisconsin–Madison [email protected] Abstract: In January 2007, Mexicans filled the Zócalo in Mexico City to express opposition to rising corn prices and corn imports. The price of tortillas had risen dramatically across the country—in some regions, prices had quadrupled since the summer. Marching under the banner “without corn there is no country,” consumers and producers, middle class and campesinos united to demand access to affordable, explicitly Mexican corn. Through an analysis of the discourse and symbols deployed during the tortillazo, this paper explains both the cooperation across sectoral lines and the participation of a largely unorganized consumer base by focusing on corn itself. How corn took on meanings in the Mexican context explains the broad-based appeal of the the tortillazo protest. For many Mexicans, tortillas, and corn more generally, are not only a cornerstone of both urban and rural diets but also appear in well-known myths, serve as a centerpiece of daily ritual, and are part of how many conceive of themselves as Mexican. When individuals imagined that they or other Mexicans might not be able to consume a good at the center of daily life and imaginings of nation, they reached across established divides and took to the streets. These insights help us better understand broader patterns of mobilization and quiescence in response to market reforms, reminding us not only of the contingent and conditional character of protest but also of the importance of attention to what markets—and the goods getting marketized—mean across contexts.

  • The H1N1 Virus and Mexican Baseball Attendance
    Athens Journal of Sports - Volume 4, Issue 4 – Pages 263-276 The H1N1 Virus and Mexican Baseball Attendance By Seth R. Gitter In 2009 the H1N1 virus severely affected many Mexican industries and decreased total GDP by as much as 0.5% according to some estimates. This study examines the relationship between the outbreak and social gathering. Using data from the Mexican National Health Service and Mexican League baseball game we find that the H1N1 outbreak reduced baseball game attendance by 15- 30% with a greater reduction in attendance where there were more reports of influenza-like illness. Furthermore, when the Mexican government used moderate social distancing measures that discouraged public gatherings, such as attending a baseball game, attendance declined an additional 20% controlling for the current infection reports. Keywords: H1N1, Mexico, Baseball, Social Distancing. Introduction In May 2016, a group of 150 public health experts wrote an open letter to the World Health Organization (WHO) urging the postponement of the 2016 Summer Olympic Games in Rio de Janeiro out of concern for the potential to increase the spread of the Zika virus (Sun 2016). Sporting events with high attendance have the potential to spread an outbreak. The WHO and public health officials have had mixed success using public health warnings to reduce large gatherings during outbreaks such as the Severe Acute Respiratory Syndrome (SARS) in 2003 and H1N1influenza in 2009. The economic implications for these outbreaks are large, as Dixon et al (2009) estimate that a pandemic of 60 million flu infections in the US would decrease GDP by nearly 3% in one year.

    Mexico-U.S. Relations: Issues for Congress Clare Ribando Seelke Specialist in Latin American Affairs February 15, 2011 Congressional Research Service 7-5700 www.crs.gov RL32724 CRS Report for Congress Prepared for Members and Committees of Congress Mexico-U.S. Relations: Issues for Congress Summary The United States and Mexico have a close and complex bilateral relationship, with extensive economic linkages as neighbors and partners under the North American Free Trade Agreement (NAFTA). In recent years, security issues have dominated U.S.-Mexican relations, as the United States has supported Mexican President Felipe Calderón’s campaign against drug trafficking organizations (DTOs) through bilateral security cooperation initiatives including the Mérida Initiative, an anti-crime and counterdrug assistance package first funded in FY2008. Immigration and border security have also returned to the forefront of the bilateral agenda since Arizona enacted a controversial state law against illegal immigration (S.B. 1070) on April 23, 2010. In response to rising concerns about border security, President Obama deployed 1,200 National Guard troops to support law enforcement efforts along the U.S.-Mexico border and the 111th Congress approved $600 million in supplemental funds for border security (P.L. 111-230). Now in the fifth year of his six-year term, President Calderón of the conservative National Action Party (PAN) is focused on strengthening the Mexican economy, which grew by 5% in 2010 after contracting by 6% in 2009, and combating organized crime and drug trafficking. Although the Calderón Administration has arrested several top drug kingpins, the persistent and increasingly brazen violence committed by the DTOs has led to significant criticism of Calderón’s anti-drug strategy.

  • Two Die of A(H1N1) Swine Flu in Mexico: Official 22 January 2012
    Two die of A(H1N1) swine flu in Mexico: official 22 January 2012 An outbreak of A(H1N1) swine flu claimed the lives of two people -- 19 and 21 years old -- in Mexico's capital in the first weeks of the year, health authorities said Saturday. The health secretary of Mexico's Federal District, Armando Ahued, said there were 138 confirmed cases of the flu, including 110 cases of A(H1N1), a novel strain of the swine flu that was first detected in 2009. Nationwide, 333 cases of the virus have been confirmed, the federal government's health secretary said earlier in the week, without saying how many deaths had been attributed to it. The latest victims were a 19-year-old and a 21-year-old who died in separate hospitals. "The tendency toward an increase in flu cases is normal because January is the month with the lowest temperatures," said Ahued adding that the incidence of flu should begin to subside in February. The first outbreak of the A(H1N1) virus occurred in April, 2009 in Mexico and the United States, and quickly became a global pandemic that claimed the lives of 17,000 people. In Mexico alone, more than 1,250 people died. The World Health Organization declared the pandemic over in 2010 as the flu returned to typical seasonal patterns.
