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.

Victory in Colombia: Citizens Vote to Ban Mining in their Territory
On March 26, 2017, 98% of voters in Cajamarca, Colombia decisively rejected mining in their territory. The results of the referendum (or “popular consultation”) are binding under Colombian law. Now municipal authorities must issue regulations to implement the ban. AIDA was part of the legal team that advised the Cajamarca community and developed a strategy, including the referendum, to stop a proposed mine that threatens to pollute the water supply. AngloGold Ashanti was in the exploration phase of a project called La Colosa (the Collosus)—aptly named, because it would be among the world’s 10 largest open-pit gold mines, the second-largest in Latin America. In a country coming out of a 50-year civil war, the referendum is a victory not only for the environment, but also for democracy. Banning mining through popular consultation demonstrates a commitment to solving environmental conflicts in a peaceful and participatory manner. It also allows citizens to exercise their human right to have a voice in public issues that affect them—a key element of true democracy—and to safeguard their human right to a healthy environment.

Lowering Peru’s air quality standards is regressive and harmful to public health
The government of Peru has proposed increasing the legal amount of sulfur dioxide in the air by more than 12 times and doubling the allowed level of particulate matter, substances known to cause serious health harms. The proposal ignores both scientific evidence and the government’s obligation to uphold conditions that are suitable for human life and health. Lima, Peru. Peru’s Environment Ministry has proposed new National Environmental Quality Standards for air, which would impact the health of Peruvians everywhere. The proposed standard increases by more than 12 times the limit for airborne concentrations of sulfur dioxide (SO2) and doubles the allowable amount of fine particulate matter. The increased limits ignore scientific evidence that finds these substances can cause lung problems and other illnesses, particularly among the most vulnerable populations such as people with asthma, children, and the elderly. “There is overwhelming scientific evidence to conclude that sulfur dioxide pollution poses a serious health risk, particularly when the contamination reaches high levels over short periods of time, something the proposal does not take into account,” said Anna Cederstav, co-director of the Interamerican Association for Environmental Defense (AIDA). AIDA prepared comments on the proposal that were presented to the government of Peru together with APRODEH. These pointed out that, contrary to the government’s assertion, reducing sulfur dioxide levels in the air would lead to longer life expectancy. This is because, among other reasons, sulfur dioxide also promotes the formation of PM2.5, small particulate matter that lodges in human lungs and causes acute respiratory problems such as bronchitis and pneumonia, as well as premature death. The government proposes to simultaneously double the legal limit for these extremely harmful particles. The organizations also highlighted flaws in the public consultation process. The government published the draft standard on Saturday, April 8, just before the Easter week holiday, giving only 10 working days for public comment on this critical public health issue. They also failed to make public the entire scientific and technical basis for the proposal. In so doing, the government has violated the rights to information and public participation. The comments also emphasize that the government’s proposal violates the American Convention on Human Rights and other international treaties to which Peru is a party, by failing to guarantee the human rights to life and health. While the proposed changes would impact Peru’s entire population, the residents of cities with high levels of pollution, such as La Oroya, would suffer the most severe impacts. La Oroya is an emblematic case because the metallurgical complex operating there—which has for decades been a macro-emitter of pollutants—is in the process of being sold. The government has publically acknowledged that the weakening of the air quality standards is an attempt to promote the sale of the complex. But it ignores the effects those relaxed standards would have on the people of La Oroya, who have seen significant improvements to both their air quality and their health in recent years. People affected by the pollution in La Oroya have sued the State before the Inter-American Commission on Human Rights in an attempt to protect their rights. For ten years, they have been granted precautionary measures due to the risk the pollution poses to their health and life; those measures were recently extended to additional people because the level of risk has continued. “Relaxing air quality standards to facilitate the sale of the complex and increase investment in Peru would be a setback for the protection of health and the environment, which could result in the State being held responsible before the Inter-American Court on Human Rights,” said Christian Huaylinos of APRODEH. “In addition, such actions would violate free trade agreements signed by Peru with the United States and the European Union.” Consult the comments sent to the Environment Ministry of Peru and more information on the case of La Oroya.
