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.

Lithium unveiled: Origins, extraction and environmental implications
One of the paradoxes of the energy transition is that it replaces the use of fossil fuels with mineral resources whose extraction and refining can have negative impacts on ecosystems, species and communities. This is happening with lithium, a mineral that has traditionally been used in glass and ceramics to provide greater adhesion and hardness, but is now being used primarily to make the batteries required by technologies that eliminate or reduce the use of fossil fuels. This has led to an increase in its demand. The serious social and environmental impacts of its extraction have been hidden or minimized. What makes lithium special? Lithium is a mineral in high demand due to its unique properties: It is the lightest metal with the highest electrochemical potential. It has a high energy storage capacity. It is malleable, so it can be adapted to different sizes, shapes and designs. These qualities make it a key material in the manufacture of batteries for cell phones, computers and, most importantly, electric vehicles. Lithium is considered key to the energy transition because it can be used to store non-conventional renewable energy, such as wind and photovoltaic power. Where it is: The so-called "lithium triangle"? The primary sources of lithium are salt flats, which are wetlands covered with a saline crust that contain brines, bodies of water in which many salts and elements, including lithium, are dissolved. Salt flats are attractive to the mining industry because of the relative technical ease of exploitation, low operating costs and low energy requirements to extract lithium from them compared to other sources. Worldwide, the salt flats of Argentina, Bolivia and Chile account for 54 percent of lithium resources (potentially mineable material). In addition, Argentina and Chile hold 46 percent of the world's lithium reserves (the portion of known resources with a high level of confidence and proven economic viability). The mining industry has dubbed the region where the mineral is concentrated the "Lithium Triangle" - because that is all they see there - which includes northeastern Argentina, northern Chile and southern Bolivia. But there is much more than lithium in this region. There are also communities, ecosystems and species that depend on these salt flats. The region's inhabitants are engaged in small-scale ranching and subsistence agriculture, activities that require water, an already scarce resource in these latitudes. How is lithium mined from the salt flats? The procedure is as follows: The salt flat is drilled. The brine is poured into large pools or basins. Wait for the water to evaporate so that the lithium concentration increases. When the concentration is sufficient, the brine is sent to an industrial plant. The brine is chemically treated to produce lithium carbonate, which is marketed for battery production. Lithium extraction, especially by this method, involves huge consumption and loss of water because: Water is lost in pumping brine. Evaporation in ponds requires two million liters of water for every ton of lithium produced. Water is also needed in the final processes to obtain lithium carbonate and separate it from the rest of the compound. Lithium mining is threatening South America's salt flats, which are Andean wetlands, affecting local water availability and threatening the survival of communities and species living around these fragile ecosystems. The energy transition is urgent, but it must be equitable and not at the expense of other natural resource extraction that endangers people and the environment. sources -Maritza Tapia, “Claves del litio: el metal más liviano y con mayor potencial electroquímico”, Universidad de Chile. -Heinrich Böll Stiftung Colombia, “Litio: los costos sociales y ambientales de la transición energética global”. -Florencia Ballarino, “¿Qué es el litio, para qué sirve y de dónde se extrae en la Argentina?”, Chequeado. -Wetlands International, “El impacto de la minería de litio en los Humedales Altoandinos”. -Rodolfo Chisleanchi, “‘Triángulo de litio’: la amenaza a los salares de Bolivia, Chile y Argentina”, Mongabay Latam. -U.S. Geological Survey, Mineral Commodity Summaries, January 2023, “Lithium”.

5 years of the Kawésqar National Reserve: pending issues for its protection
Local communities denounce that the area is highly affected by salmon farming, which is failing to comply with environmental regulations.On January 30, 2019, the Official Gazette published the decree creating the Kawésqar National Reserve in Magallanes, which extends over 2,842 hectares between fjords and Patagonian peninsulas. The purpose of this classification was to guarantee the protection of the area, its territory and biodiversity, as well as to establish that it is the duty of the State to ensure its conservation. This year, 2024, marks the fifth anniversary of this milestone, which begs the question: is the reserve's objective being achieved? The community's claimsWith the qualification of National Reserve, this area was separated from the Kawéskar National Park, which offers broader protection. In the opinion of the local communities, this administrative division determines in a whimsical way what to prioritize and separates the land from the sea, as if they were independent elements, which causes "divisions and confusion to grow at all levels," says Eric Huaiquil Caro, a member of the Kawésqar Communities Kawésqar Family Groups Nomads of the Sea. He also says that the "agreements that were made in the indigenous consultation have not been responded to." Finally, Caro asks that the conservation of this reserve be done "without salmon farms and we hope that this will be established in the Management Plan that will be submitted for consultation in March 2024." An overstressed areaWithin the Kawésqar National Reserve lie the richest kelp forests in the country, an ecosystem considered key to combating climate change, as they can absorb high levels of carbon dioxide and regenerate marine systems. Although the State must guarantee their protection, the area is experiencing great pressure from the salmon farming industry. For example, there are 133 approved concessions in the entire Magallanes Region and 85 in process, of which 68 approved and 57 in process are in the Kawésqar National Reserve, "which seems unusual to us because it has been proven that the salmon farming industry is neither sustainable nor compatible with the ecosystemic care of the reserve. This is fundamental to the creation of the Reserve's Management Plan, which is currently being designed and which should establish the incompatibility of the industry within the zone's protection mandate, as documented in the report we have prepared together with the communities," says Cristina Lux, an attorney with the Interamerican Association for Environmental Defense (AIDA)."Forty-three percent of the concessions approved within the Kawésqar National Reserve have presented anaerobic conditions within the framework of their operations, according to information obtained from the Environmental Reports for Aquaculture. This means that they suffer or have suffered total or partial loss of oxygen, which affects the living conditions of all of the area's biodiversity," adds Estefanía González, Campaigns subdirector at Greenpeace Chile.The impact, explains Sofía Barrera , an attorney for FIMA, is "enormous and highly destructive.""To begin with, these farming centers are concentrated in just seven sectors (Staines Peninsula, Taraba Sound, Poca Esperanza Strait and Vlados Channel, Glacier Sound, Skyring Sound, Desolation Island and Xaltegua Gulf), which also concentrates their synergistic effects. Some of these are the impact of boat routes, the killing of sea lions to prevent them from attacking the salmon cages, the overproduction of salmon, the presence of garbage outside the concession polygons and the detection of the ISA virus in the farming centers, which ends up making the rest of the marine ecosystem sick, something that has been recognized by Environmental Courts," adds Barrera. "In addition, the dispersion of organic matter from the cultivation centers causes eutrophication and harmful algal bloom events (HAB), generating significant changes in water quality and affecting marine life," adds González.In the opinion of the representatives of these three organizations, despite the legal prohibitions and environmental requirements, the fact that many of these projects have been submitted and approved through environmental impact statements raises legal and political questions. "Why are the authorities not ensuring the real care of this area, whose interests are being taken care of, and how is the salmon industry influencing our authorities," asks Barrera.Unfortunately, González adds, when explanations have been requested, "we have not received answers or certainty. That is why it is urgent to advance towards a management plan that really protects this ecosystem and does not allow more centers that put biodiversity at risk."

Our vision for a just future
Latin America is key to protecting biodiversity and combating the global climate crisis. Its forests, wetlands and marine ecosystems are among the most important carbon sinks on the planet, a service weakened by activities such as the exploitation and use of fossil fuels. At AIDA, we envision a region where the environment and communities, especially those in highly vulnerable situations, have lasting protections. To achieve this, we select precedent-setting cases that result in new, replicable tools and strategies that add to the protection of a healthy environment in the region. Having celebrated 25 years of working for the right to a healthy environment in the region, AIDA is poised to enter a new quarter century as a robust, multidisciplinary organization. In the coming years, we will continue and strengthen our pursuit of environmental and climate justice through two interconnected initiatives, each with defined lines of work: 1. Promotion of a just energy transition A just energy transition implies transforming the power relations between those who pollute the most and the rest of the world, avoiding the deepening of socio-environmental conflicts and protecting the rights of communities and people involved in energy generation processes. As this is an issue that cannot be addressed only at the national level, AIDA will contribute its regional vision to increase the scope of local and national decisions, enhance legal strategies, and strengthen a proposal for the continent’s transition. We will focus on: Avoiding dependence on oil and gas. Halting the extraction and use of coal. Promoting renewable and sustainable energies. Advocating for human rights-based climate finance and governance. 2. Protection of life-sustaining systems The ecosystem services that sustain life in Latin America and the world—including natural carbon capture and storage to mitigate the climate crisis, and the provision of clean food, air, and water - are at risk due to the lack of ambitious and effective actions. To ensure the livelihoods of life systems on the continent, both in rural communities and large cities, AIDA will focus its efforts on: Protecting the ocean, from the coasts to the high seas. Preserving freshwater sources and traditional territories. Defending culture and traditional livelihoods. Improving air quality. In the coming years, from our regional perspective, we will continue to contribute to solutions that center nature and communities, and that effectively address the continent’s social and environmental challenges.
