Known as an “ecological treasure house,” the Sierra La Laguna Biosphere Reserve at the southern tip of Baja California will not be spoiled by toxic mine waste, thanks in part to AIDA’s advocacy.
The reserve was once an island, so it’s home to rare plant and animal species. Canyons, swimming holes, and hot springs can be found in its granite mountain range and lowland tropical forests.
Thanks to AIDA and our partners in Mexico, the Mexican government denied an environmental permit for the Paredones Amarillos gold mine, halting the project for the time being. To protect the biosphere reserve, AIDA helped educate community groups and decision makers about the mine's risks. This helped to build the political momentum necessary for the government to deny the permit.
To extract gold from the mountains, the Canadian company Vista Gold proposed to carve out huge quantities of rock—each ton containing a mere gram of gold–-grind it into sludge, and treated it with cyanide. The company planned to dump massive amounts of toxic waste (called “tailings”) behind a dam intended to store it forever. Unfortunately, tailings dams can break for various reasons, as happened at Bolivia’s Porco mine in 1996. When that dam collapsed, more than a quarter million metric tons of tailings flooded the river and contaminated 500 miles (800 km) of waterways in Bolivia, Argentina and Paraguay.
The mine could also cause acid mine drainage. When sulfur-containing rocks are exposed to air and water, sulfuric acid forms, which causes toxic heavy metals to dissolve and drain into the watershed. The risk of acid mine drainage in Sierra La Laguna was significant and the human and environmental cost would have been tremendous: thousands of people and countless wildlife in the reserve rely on its water for survival.
Depleting freshwater is a further threat because mines use tremendous quantities of water. Owing to the scarcity of water in the reserve, Vista Gold proposed to build a plant on the Pacific coast to remove salt from sea water in a highly energy-intensive process, and then pump the water 45 km to the mine site. The desalination plant posed a threat to the endangered leatherback sea turtle.
Singly and together, the mine’s impacts would have devastated a rare jewel, a unique and lush paradise worth saving for future generations.

Belo Monte: Fueling Our Fight for Justice
By María José Veramendi Villa Even as the turbines of the Belo Monte Dam have begun turning, the fight for justice continues. The ongoing operation of the world’s third largest dam—corrupt and careless as it is—cannot stop us. In fact, each new allegation of corruption and abuse only fuels our desire for justice for those who have been affected by the dam. And our most important battle is now strongly underway: our case before the Inter-American Commission on Human Rights, which opened for processing at the close of last year. In it, we’re working to hold Brazil accountable for the countless human rights violations that have been committed in the name of the Belo Monte dam: the absence of consultation with and free, prior and informed consent of indigenous communities; the lack of adequate assessment of environmental and social impacts; forced displacement; and severe violations to the rights of indigenous peoples, riverine communities and residents of Altamira. We’re in the process of getting the case admitted before the Commission, so they can establish—as an independent, international body—if these violations occurred and whether the State must respond for them. As part of the process, Brazil had to respond to our allegations before the Commission. We received their response on August 9 and have just submitted our legal submission to counter their claims. We need to ensure Commission understands the importance of their role in investigating the human rights abuses that have been suffered due to Belo Monte. Even as I write this, the State and dam operators continue to blatantly disregard the human rights of the people of the Xingu River basin, living in the dam’s shadow. On September 1, for instance, the dam’s operating license was suspended yet again because sanitation systems in the city of Altamira—a legal obligation operators were required to meet long ago—were never installed. Wastewater still floods the streets of Altamira, and threatens to turn Belo Monte’s reservoir into a stagnant pool of sewage. Unfortunately, as with many legal decisions attempting to protect the rights of those affected, the suspension was overturned a few weeks later. It’s clear the forces behind Belo Monte have no respect for the environment in which they’re working, and even less for the local people who depend upon the river and forests for their survival. Many of the people we represent live in the neighborhoods of Altamira, and are exposed to raw sewage. Those who live outside the city have been displaced from their land, cut off from their primary water source, or have had their way of life destroyed. We must ensure the Brazilian State is held accountable for the immense environmental and social damage the dam has caused. Rest assured, we won’t stop until we achieve justice for the people of the Xingú.

Civil society urges World Bank to withdraw funding from Colombian mining project
Organizations argue that the International Finance Corporation invested in a gold mine without taking into account potential environmental impacts, thereby failing to comply with its own investment standards. The proposed mine threatens Colombia’s Santurbán Páramo, a high-Andean ecosystem that provides water to millions of people. Washington, DC. A coalition of civil society organizations met at World Bank headquarters yesterday to demand that the International Finance Corporation (IFC), a member of the World Bank Group, withdraw its investment in the Angostura mine. The proposed gold-mining project would be located in Colombia’s Santurbán Páramo, a high-Andean ecosystem that supplies drinking water to more than two million people. The organizations also delivered a petition, signed by thousands of people from throughout the Americas, calling on IFC to withdraw its investment immediately. To present their demand, the organizations met with representatives of the IFC. They are also meeting with members of Congress and representatives of the US Department of State to discuss the situation in the Santurbán páramo and the risks its defenders face. The Committee for the Defense of Water and Páramo of Santurbán led the coalition, with support from the Center for International Environmental Law (CIEL), the Interamerican Association of Environmental Defense (AIDA), the Center for Research on Multinational Corporations (SOMO), and Mining Watch Canada. The demand presented yesterday tops off an important year in the fight to defend Santurbán. In March, the Canadian company developing the mine, Eco Oro, announced its intention to file an international arbitration suit against the Colombian government. In February Colombia’s Constitutional Court issued a ruling that bans all oil, mining, and gas operations in the country’s páramos. In August, an independent investigation undertaken by IFC’s internal watchdog, the Compliance Advisor Ombudsman, found that the investment in Angostura did not take into account the project’s potential environmental impacts, thus failing to comply with IFC’s own investment standards. The investigation was triggered by a complaint filed by the Committee and supported by the international organizations.

The Green Climate Fund: Summary of Decisions of the Board of Directors (in Spanish)
This report offers an overview of the development, evolution and current state of the Green Climate Fund. It includes a summary of the decisions made thus far by the Board of Directors. It also highlights the progress made by the Fund, and the challenges it must overcome in order to achieve its objectives. In 2010, the United Nations Framework Convention on Climate Change created the Green Climate Fund with the goal of contributing significantly and ambitiously to the goals set by the international community to combat climate change. The Fund will be the primary mechanism through which developing nations receive financial resources from developed nations to undertake adaptation and mitigation activites that will help them confront extreme changes in climate. The Latin America nations that are members of the Convention will be beneficiaries of the financing. That’s why a clear understanding of the objectives and operation of this institution can contribute to better use of these resources in the region. Download the report (in Spanish)
