10 environmental news stories to end 2025 on a hopeful note

We are nearing the end of a complex year, and taking stock seems daunting. Multilateralism is faltering as environmental crises worsen and urgently demand decisive action.In such turbulent times, it is worth taking stock of what we, as humanity, have achieved in building a more just and sustainable world for all who inhabit it.2025 will be remembered as the year when an underwater expedition thrilled us in real time, when we celebrated the implementation of agreements to protect life in the ocean, and when international court rulings transformed the pursuit of justice to protect people and the environment from the climate emergency.These are some of the environmental victories that this year has left us with, and they deserve to be celebrated, just as we honor the fire that shines in the darkness. Because even with small lights, we can continue to illuminate a path of hope toward environmental and climate justice. 1. International courts issued landmark decisions for climate justiceThe Inter-American Court of Human Rights and the International Court of Justice released their respective advisory opinions on the climate emergency. Both decisions clarified the obligations of states to protect the rights of people and nature in the face of the climate crisis.These decisions are part of an unprecedented global movement for climate justice, which also includes the advisory opinion issued in 2024 by the International Tribunal for the Law of the Sea and similar future decisions, such as the one expected from the African Court on Human and Peoples' Rights.Learn More: Dialogue Earth 2. Climate litigation exceeded 3,000 cases worldwideClimate litigation reached 3,099 cases worldwide, according to a report by the Sabin Center for Climate Change Law and the United Nations Environment Program. Although climate litigation in countries in the global south is still in the minority (9.8% of the total documented), it has grown steadily. Brazil stands out as the third country with the most cases in the world (135), and other Latin American countries (Mexico, Colombia, Argentina, and Chile) are among the top 15 with the most cases reported.This growth demonstrates the increasing use of strategic litigation to promote concrete action on the causes and consequences of the climate crisis.Learn More: Sabin Center for Climate Change Law 3. Colombia declared its part of the Amazon free from oil and large-scale mining activitiesDuring the 30th UN Climate Change Conference (COP30), Colombia declared the entire Colombian Amazon region a zone free from oil and large-scale mining activities, announcing it as a "reserve zone for renewable natural resources."The decision implies an unprecedented limitation on the expansion of mining and hydrocarbon activities in more than 48 million hectares, equivalent to 7% of the entire Amazon region. It is also a call to other Amazonian countries to follow suit.Learn More: InfoAmazonia 4. Countries create a global mechanism to promote a just energy transitionAn important step forward at COP30 was the adoption of the Belém Action Mechanism, created within the framework of the Just Transition Work Program.The mechanism will function as a coordinating space to centralize global initiatives, offer technical assistance, and strengthen international cooperation. It is an achievement driven by civil society to promote ambitious climate action and a transition that does not repeat the mistakes of the fossil fuel era.Learn More: AIDA and The Climate Reality Project América Latina 5. An underwater expedition in Argentina marked a scientific and technological milestoneThe expedition "Underwater Odel Plata Canyon: Talud Continental IV," led by scientists from Argentina's National Scientific and Technical Research Council, in collaboration with the Schmidt Ocean Institute, explored the deep ocean in the Mar del Plata submarine canyon for 21 days, while broadcasting live on YouTube and Twitch.The result: 40 new marine species and an unexpected diversity of cold-water corals were discovered, findings that were seen and celebrated in real time by millions of people.Learn More: CONICET 6. The High Seas Treaty will finally enter into forceIn a process that took more than two decades, the High Seas Treaty this year reached the 60 ratifications needed to trigger its entry into force, which will occur on January 17, 2026. This binding agreement allows for the protection of the part of the ocean outside of national boundaries, almost half of the planet, through the creation of marine protected areas in international waters and the conduct of environmental impact assessments of planned human activities on the high seas.  This is a historic milestone for the protection of the ocean and the well-being of millions of people in Latin America and around the world.Learn More: AIDA 7. Implementation begins on agreement ending harmful fisheries subsidiesThe World Trade Organization's Agreement on Fisheries Subsidies came into force in September this year. It is the first multilateral trade treaty to prioritize environmental sustainability, as well as a milestone in ensuring food security and the livelihoods of coastal communities.The agreement prohibits government subsidies that promote illegal fishing and the depletion of overexploited stocks.Learn More: WTO 8. Green sea turtles are no longer considered an endangered speciesAfter decades of decline, the population of green sea turtles is recovering. The International Union for Conservation of Nature no longer considers them endangered and has reclassified them as a "species of least concern."This sea turtle population has increased thanks to decades of conservation work to protect nesting areas, reduce capture, and prevent bycatch. AIDA was part of these efforts, protecting them in the 1990s from hunting—which was legal at the time—in Costa Rica.Learn More: AIDA and IUCN Red List 9. Protection of key ecosystems around the world, including the Galapagos, is growingUNESCO added 26 new biosphere reserves in 21 countries, the highest number in 20 years, and approved the expansion of 60,000 square kilometers in the Galapagos Biosphere Reserve in Ecuador to incorporate the Hermandad Marine Reserve.  This will protect the area where dozens of marine species, many of them protected, transit, and which is considered one of the most diverse ocean corridors in the world.Learn More: LaderaSur and Government of Ecuador 10. Deforestation decreased in Afro-descendant territories in Latin AmericaAfro-descendant communities in Brazil, Colombia, Ecuador, and Suriname have significantly reduced their deforestation rates, according to new research from Conservation International.The study showed that Afro-descendant communities are critical to environmental conservation, as 56% of their lands are located in the 5% of the world with the highest biodiversity.Learn More: Conservation International 

Our Contribution to Environmental Justice in 2025

At AIDA, one of our core pillars is using the law strategically — backed by science and international advocacy — to set important precedents that protect the environment and human rights across Latin America.This year, our work helped strengthen both regional and global legal frameworks so they can better respond to the social and environmental challenges we face today.These advances led to the creation of key legal tools that open new opportunities to defend communities and their territories, protect the region’s biodiversity, and hold governments and companies accountable.The progress we saw in 2025 highlights the transformative power of law, science, and the collective strength of communities when they work together. 1. Two new global treaties restore hope for the ocean — and for all of usThis year brought two historic achievements that could change the future of the ocean, and our own.The first is the ratification of the High Seas Treaty, which will take effect in January 2026. This legally binding agreement creates shared rules and a system of multilateral governance for the ocean areas beyond national jurisdiction — nearly half the planet.The second milestone is the entry into force of the World Trade Organization’s Agreement on Fisheries Subsidies. For the first time, a multilateral trade treaty puts environmental sustainability front and center by banning government subsidies that fuel illegal fishing and the depletion of overfished stocks.AIDA played an important role in ensuring Latin America’s perspectives were reflected in both agreements. We provided technical support to government representatives throughout the process, and we continue working to make sure these treaties lead to real, effective action across the region.Learn More 2. Maya community in Guatemala achieves a landmark environmental victoryIn Chinautla, Guatemala, the Poqomam Maya community won an unprecedented court ruling over decades of river pollution that violated their rights. The court ordered the municipality to carry out studies, programs, and plans to reduce pollution — and to ensure the community is involved every step of the way.This is the first time a court in Guatemala has recognized both a people’s right to a healthy environment and their central role in finding solutions. The ruling could inspire other municipalities along the Motagua River, the country’s longest river, where pollution also threatens the Mesoamerican Reef.Beyond providing legal support, AIDA helped the community document illegal dumping that harmed their water sources. This hands-on “community science” effort played a crucial role in both the lawsuit and the historic ruling.Learn More 3. Corte Interamericana marca un antes y después para la justicia climáticaOn July 3, the Inter-American Court of Human Rights issued its long-awaited Advisory Opinion 32 on human rights and the climate emergency — a landmark moment for climate justice both regionally and globally. The Court clarifies the legal obligations of states to protect people and communities affected by the climate crisis, opening new pathways for justice in national and international courts, climate negotiations, and public policy advocacy.For the first time, the Court recognized the right to a healthy climate and affirmed that states have a duty to prevent companies from violating human rights in the context of climate change.Ahead of this decision, AIDA helped amplify the voices of communities across the region, facilitating their testimony before the Court and presenting our own arguments for recognizing the right to a stable and safe climate.Learn More Discover the stories behind these victories and our full review of the year in our 2025 Annual Report.

Protecting the Environment Through Collaboration: A Community Science Experience

When environmental damage occurs, the first warning often comes from the people or communities directly affected. Residents living near a river are usually the first to notice waste being dumped or fish dying when the water is polluted. Similarly, who live near an open pit mine are the who see when illness becomes more common or when water begins to run scarce.One powerful way to turn lived experience into scientific evidence is through community science. This approach allows people to share, validate, and integrate local knowledge into scientific research and efforts to defend their territories.At AIDA, we believe in the power of science to advance environmental justice. That’s why we generate and apply scientific knowledge in the legal cases we support. Recently, we had the opportunity to take part in a community science initiative that helped us reflect on—and learn from—the value of this collaborative methodology and the shared knowledge it produces.  Local Knowledge: A Powerful Response to Environmental Degradation In April 2024, at the request of the Poqomam Maya community of Santa Cruz Chinautla—a village near Guatemala’s capital—AIDA senior scientist Javier Oviedo and attorney Bryslie Cifuentes carried out a field visit to gather information and assess the solid waste pollution that has affected the community for years.One of their main objectives was to identify illegal dump sites on the banks of the Chinautla River. The disposal of waste and debris in this area has contaminated both the soil and waters of this tributary of the Motagua River, the longest river in Guatemala.While preparing for the trip, Javier realized the team would face several challenges. The time available would not be enough to collect all the necessary data, and the team’s limited familiarity with the area could make locating the dumpsites difficult and potentially unsafe.Then Javier had an idea: to involve members of the community in supporting the team with this task.His plan made perfect sense—after all, who better to locate the illegal dumpsites than the people who know the territory best? Beyond that, by witnessing the impacts of pollution firsthand, community members could also appreciate the importance of documenting these issues.I spoke with Javier about how this idea came about, and he shared the following:  Beyond seeking support from community members, this approach was rooted in a recognition of the irreplaceable value of their knowledge as residents of their territory.  How the Work Was Carried Out Javier’s idea was that, with the help of an accessible and easy-to-use mobile app, community members could send information about illegal landfills directly to the AIDA Science team, who would then validate and analyze the data.To make this possible, the team designed a form specifying the data they needed to collect: the location of the landfill, its dimensions, the type of waste identified, associated social issues, and other relevant details.In Chinautla, two community residents, along with authorities from the Poqomam Maya village, visited several landfills they had previously identified with Javier and Bryslie. During these visits, Javier showed them how to use the app and fill out the form. Later, one of the residents continued the process independently.Thanks to this collaborative effort, data was collected on 10 of the most critical illegal dumpsites. While this does not capture all of them—unfortunately, many more exist—this sample allowed the team to estimate the extent of waste and debris pollution in the community and to illustrate how poor management has exacerbated the problem.The information gathered was crucial in highlighting the severity of the pollution, demonstrating the continued use of illegal dumping, and exposing the municipal authorities’ failure to meet their legal obligations regarding waste management.This evidence formed the basis for the lawsuit the community filed against the municipality of Chinautla in October 2024, citing the lack of measures to address river and soil contamination caused by inadequate waste management and illegal landfills. In June 2025, an appeals court ordered the municipality to take action to address the serious environmental crisis affecting the community.  Lessons Learned from the Experience According to Javier, involving the people of Chinautla in a knowledge-building process led to mutual learning.For community members, it meant acquiring new technological skills. For the AIDA team, it prompted new questions about how to move knowledge-sharing with a community beyond simple collaboration.Javier summarized his learnings in three points:   At AIDA, science is a core part of our work and a key element of the strategic litigation we pursue to protect and defend a healthy environment across Latin America. Involving the communities we support in this process broadens our perspective, allowing us to integrate their knowledge and experiences into the science we seek to build.  

New European Union policies for mineral supply: What are the implications for Latin America?

Amid the global race for minerals for the energy transition, digitalization, and the defense and aerospace industries, the European Union (EU) has adopted an industrial policy to secure its access to "critical" raw materials, including lithium. According to the Economic Commission for Latin America and the Caribbean, 25 of the 34 raw materials the EU considers essential are found in Latin America's indigenous territories and strategic ecosystems. Civil society warns that the Critical Raw Materials Act (CRMA) and other recent policies aimed at deregulation and promoting the defense sector (Omnibus I and II) could deepen historical inequalities between Europe and Latin America.In this webinar, we addressed the threats to Latin America by the European Union's new policies and what the region's states and civil society can do to address them. To this end, we focused on the significance of the "strategic partnerships" that the EU has signed with Chile and Argentina, and explained what the so-called "strategic projects" that the EU intends to consolidate at the global level to maintain the flow of minerals from South to North consist of. Indigenous leaders denounced how excessive water use in lithium mining has already degraded Andean wetlands and caused the loss of biodiversity and culture.In this session, we debated the justice of the "European green transition," which, in the name of decarbonization, threatens to open up new sacrifice zones in the Global South, while erasing ancient knowledge and causing irreversible damage to carbon sinks that are essential for tackling the climate crisis. PanelAlejandro González, Senior Researcher and Advocate in SOMO's Climate Justice team and member of the EU Raw Materials Coalition.Pía Marchegiani, Deputy Executive Director and Director of the Environmental Policy area of the Environment and Natural Resources Foundation (FARN).Joám Evans Pim, Coordinator of the Confederal Mining Area at Ecologistas en Acción and Director of the Montescola Foundation.Ramón Balcázar, Director of the Tantí Foundation.Román Elías Guitián, Community Atacameños del Altiplano, Argentina.Moderator: Yeny Rodríguez, Senior Attorney and Area Coordinator, Interamerican Association for Environmental Defense (AIDA). Recording (in Spanish) 

Circular economy: what is it and what role does it play regarding the climate crisis and energy transition?

Life on the planet, including our own, depends on nature.To create more sustainable ways of life and keep global warming under control, we need to ensure healthy, resilient, and productive ecosystems.The climate crisis, as well as the pollution and biodiversity loss crises, stem from human activities that exploit nature beyond its limits, without giving it a chance to recover, degrading ecosystems and pushing them to points of “no return.”These activities are based on the conventional economic model, which is linear and follows the logic of extracting, producing, using, and discarding resources.A more sustainable use of natural resources requires a different economic model.One option among many is the circular economy, an economic model of production and consumption traditionally described as a combination of reduction, reuse, and recycling activities.However, most current approaches to the circular economy, incorporated into various public policies, focus on extending the life cycle of products that have already been manufactured. They do not comprehensively incorporate the processes of extracting the materials needed to manufacture the products or their final disposal. This considerably reduces the protection of nature and territories during the economic cycle.That is why it is important to understand what the circular economy is and what it should include, in theory and in practice, so that it can truly contribute to a more sustainable and fair world. Circular economy: Definition and challengesAs an alternative to the linear economic system, the circular economy involves closing the economic cycle through various mechanisms. These include reducing the use of virgin natural resources, increasing the use of recycled materials, and minimizing waste through the repair and reuse of products, keeping them in circulation for as long as possible.It also means creating additional value for products whose useful life has ended when their materials are used again and again.  In the face of our continued and unsustainable use of resources, the concept of the circular economy is becoming increasingly prevalent in different areas.Although it is a living and evolving concept, when it becomes public policy, most definitions of the circular economy consider its main objective to be economic prosperity, with environmental care as a secondary result.In 2020, a legal definition of the circular economy in the European Union considered it to be “aneconomic system whereby the value of products, materials and other resources in the economy is maintained for as long as possible, enhancing their efficient use in production and consumption, thereby reducing the environmental impact of their use, minimising waste and the release of hazardous substances at all stages of their life cycle” …This and other definitions show that the positive effects of the circular economy on nature tend to be taken for granted, when certain theories or practices associated with the concept may actually hinder the protection of ecosystems and the people who depend on them.This is happening with the type of circular economy promoted to make extractive processes linked to the energy transition, designed to address the climate crisis, environmentally friendly. Circular economy and energy transitionHistorically, extractive activities such as mining have degraded ecosystems and violated human rights in Latin America, creating so-called “sacrifice zones.”Today, to address the climate crisis, several international organizations have positioned an energy transition that requires doubling the production of renewable energies and electromobility to decarbonize the global energy matrix.This also implies intensifying the extraction of so-called "critical" minerals for the development of clean technologies. One of these is lithium, a mineral of which the region has large reserves.Thus, far from putting an end to it, the energy transition promoted by the Global North is renewing the historical extractivist trend, generating great pressure on Latin American territories rich in minerals for the transition, affecting ecosystems and populations near extraction areas.In this context, the circular economy is promoted as a tool to make mining an environmentally responsible process. However, international proposals in this regard do not guarantee the resilience of ecosystems or the well-being of communities.This is evident in countries such as Argentina, Bolivia, and Chile due to the growing global demand for minerals such as lithium.Currently, the circular economy applied to mining in Latin America focuses on the internal processes of mining companies, but not on the consequences that their interactions with ecosystems and communities generate in the extraction territories, without stopping the expansion of extractivism or the high socio-environmental impacts caused.Obtaining lithium for electromobility, for example, involves a complex, transnational supply chain. This includes mineral extraction, refining, the production of electrodes for batteries, battery manufacturing, and finally, the manufacture of electric vehicles.From a global northern perspective, the circular economy is mainly applied here to battery recycling and industrial improvements for mining. However, it does not include measures to protect the biophysical limits and resilience of the ecosystems where lithium is extracted, ensure environmental restoration, prevent damage to local economies, guarantee human rights, and repair those that have already been violated. Proposals from Latin America for a just circular economyTo ensure that the energy transition does not become a new extractive process that generates the same conflicts and environmental impacts that it has systematically caused and that are precursors to the current climate crisis, it is essential that the circular economy comprehensively integrates the mineral extraction territories.Circular economy schemes must avoid the creation, expansion, and/or deepening of “sacrifice zones.” They must also recognize the strategic value of ecosystems as natural capital for countries and communities, given the ecosystem functions they provide, including freshwater supply and carbon capture.To move towards a just circular economy in the extraction territories, the following principles must be respected:Protection of the human rights of local populations, guaranteeing their permanence in the territory and the continuity of their economic activities, linked to their livelihoods and their relationship with ecosystems.Promotion of environmental balance in accordance with the biophysical limits of ecosystems, recognizing their intrinsic values, which favor the conservation of their functions.Internalization of environmental costs in mineral value chains, incorporating the value of ecosystem services used for extraction into prices.Learn more in our policy brief Reimagining the circular economy from the extraction territories.

UN experts denounce threats and stigmatization against defenders of water and the Santurbán páramo; demand protection for their work

Bucaramanga, Colombia. On March 6, 2025 the United Nations Special Rapporteurs on human rights defenders, a healthy environment, water and sanitation, and the UN Working Group on Business and Human Rights sent formal letters to the governments of Colombia, Canada, and the United Arab Emirates, as well as to the companies Aris Mining and MDC Industry Holding Company LLC to denounce the threats and stigmatization faced by the Committee for the Defence of Water and the Santurbán Páramo for defending this ecosystem threatened by mining in Colombia. To date, only the Colombian government’s reply has been made public. While harassment is not new, content has recently been disseminated on social media labeling the Committee’s spokespersons as "persona non grata", endangering their lives by claiming false connections to illegal armed groups. Committee members have warned that "every day that passes without a response from the national government and the companies legitimizes those who seek to silence us".For 16 years, the committee has worked to protect the Santurban páramo - a high altitude wetland ecosystem which provides fresh water to more than two million people. Recently, they achieved recognition of part of the páramo as a Temporary Reserve Zone, which means that large-scale mining activities will be suspended for two years.Viviana Herrera, Latin America Program Coordinator at MiningWatch Canada, said, "it speaks volumes that Canada has not yet responded to the UN experts. Canada must prioritize the environmental defenders of the Santurbán Committee and their struggle to protect water."Sebastián Abad Jara, an attorney with the Interamerican Association for Environmental Defense (AIDA), said that "through these letters, the offices of the UN  recognized the committee as a coalition of rights defenders; they informed governments and companies of the clear, imminent, and specific risk to its members; and in doing so they dismantled the false narratives linking their activities to those of  illegal groups."The UN agencies emphasize that Aris Mining, its subsidiary Minesa, and all companies in its supply chain associated with the Soto Norte project — such as Calimineros — have an obligation to respect and protect human rights, especially those of environmental and water defenders."Colombia is one of the most dangerous countries for those defending water and life against extractive projects, which is why immediate action by states and companies is urgently needed to stop the stigmatization and guarantee the safety of members of the committee," said Jen Moore, associate researcher at the Institute for Policy Studies (IPS).The Committee for the Defence of Water and the Santurbán Páramo, AIDA, MiningWatch Canada, IPS, Common Frontiers Canada, and the Center for International Environmental Law (CIEL) reiterate the call by United Nations experts to the governments of Colombia, Canada, and the United Arab Emirates, as well as to Aris Mining company and MDC Holding, to safeguard the lives and integrity of the committee members.In accordance with their obligations under national law, the Escazú Agreement, inter-American law and jurisprudence, and the Guiding Principles on Business and Human Rights, we also urgently call on states and companies to respond to the substance of the letters and adopt measures — with verifiable deadlines and measurable progress — to prevent companies associated with the Soto Norte project from committing human rights violations.Only the protection and strengthening of historic leadership such as that of the Santurbán Committee in Colombia will bring us closer to environmental and climate justice. The concerns raised by the offices of the UN are a reminder that protecting those who lead the struggle for water in Latin America is an imperative of state and corporate due diligence.Press contactsCommittee for the Defense of Water and the Santurbán Páramo, [email protected] Quintanilla (Mexico), AIDA, [email protected], +5215570522107Viviana Herrera, Mining Watch Canada, [email protected], +14389931264Jennifer Moore, IPS, [email protected], +12027049011 

Motagua River: A story of contamination and a call for justice

The Motagua River, Guatemala's largest river, is severely polluted with sewage, solid waste, and other types of waste.It flows into the Caribbean Sea, so contamination reaches those waters, as well as the Mesoamerican Barrier Reef System - the world's largest transboundary reef - and the Honduran coast, causing unquantifiable social and environmental damage.Polluting activities occur throughout the river basin, including sub-basins and micro-basins.In general terms, the contamination has deteriorated the health and violated the right to water, development and a healthy environment of all the people living in the basin.The contamination of the Motagua is a problem that has been going on for decades and requires urgent long-term measures that contribute to the sanitation and integrated management of the river basin.Where is the Motagua River?The Motagua River is one of the main rivers in Guatemala. With a length of 486 km, it crosses 96 municipalities and 14 departments of the country. It originates in Quiché, a department located in the northwest, and flows into the Caribbean Sea.It is at its mouth that its flow meets the Mesoamerican Reef, which extends for approximately 1,000 km and covers the territorial waters of Belize, Guatemala, Honduras and Mexico. Thus, the pollution carried by the river deteriorates the health of the reef system, which is home to the second longest barrier reef in the world.The Mesoamerican Reef protects thousands of kilometers of coastline from currents, waves and storms. In addition to being a breeding and feeding ground for a great diversity of species, it is a carbon dioxide sink and a detoxifier of water and air. The ecological and economic health of the entire South Atlantic area depends on its conservation.In addition, pollution from the Motagua River reaches the coast of Honduras and spreads to Amatique Bay, located along the eastern coast of Guatemala and Belize. This is clearly a transboundary problem.Where does the pollution in of the Motagua River come from?The largest volume of contamination of the Motagua River comes from Guatemala City, the capital of the country, mainly through the waters of the Las Vacas River, which receives a large amount of solid waste from the Chinautla River, as well as sewage that is discharged into its waters on a daily basis.Solid waste from the Chinautla River, which flows through the municipality of the same name, comes from a landfill located in Zone 3 of the capital. Any small landslide in this landfill generates waste that is automatically dumped into the river at any time of the year.The pollution that the Chinautla river carries also consists of a large amount of sewage, generated by at least 500,000 people living in the northern part of Guatemala City, which does not receive any previous cleaning treatment.In the municipality of Chinautla there are numerous illegal landfills. In addition, many private vehicles and collection trucks dump waste on the banks of the Chinautla and Las Vacas rivers.According to data from the Integrated Environmental Management of the Motagua River Basin project, financed by the United Nations Development Program (UNDP), it is estimated that 66% of urban solid waste in Guatemala is not collected and there is no guarantee that the remaining 34% is properly disposed of. In addition, of the total number of landfills in the country, 88.32% are illegal or do not have municipal authorization.Most of the waste is dumped in streams and/or on surfaces that are susceptible to dragging, ending up in one way or another in water sources, such as the Motagua basin.In other words, the main source of contamination of the Motagua River is the poor management of solid waste and water resources in the country; the lack of compliance with existing regulations on wastewater discharge, disposal and treatment of waste and solid waste; as well as the lack of a water law.Who is affected by the contamination of the Motagua River?The contamination of the Motagua River affects the entire population of Guatemala. In the lower basin, it directly affects people dedicated to fishing, who have seen their catches reduced.And, by harming tourism in the Caribbean, it also affects the communities that depend on tourism for their livelihoods.As a basin-wide problem, the contamination of the Motagua affects those living in the main sub-basins and micro-basins of the river, including the indigenous communities of the Mayan Poqomam people in the cities of Chuarrancho and Chinautla.In Chinautla, the contamination affects the living conditions, health, environment, water sources, economy and culture of more than 18,000 people.The restoration of the Motagua River is crucial to improve the quality of life of at least 30% of the Guatemalan population, as well as those affected in neighboring countries.Actions to rescue the Motagua River from contaminationIn the face of the serious degradation of Guatemala's largest river basin, the damage to key ecosystems such as the Mesoamerican Reef, and the human rights violations that pollution generates, urgent measures are required, among them:Verify compliance with environmental and municipal regulations, as well as prevent and halt environmental damage at the source through regulation, monitoring, supervision and oversight of activities that affect the rights of the inhabitants of the Motagua River basin.Strengthen regulations related to wastewater disposal and solid waste management so that they are implemented in a timely manner through complete treatment systems in the municipalities of the basin.Initiate actions to enable the socio-environmental restoration of affected ecosystems throughout the basin, including political, legislative and administrative measures to strengthen the legal system and allocate sufficient financial resources to ensure the protection of waters and territories. 

Why is lithium mining in Andean salt flats also called water mining?

By Víctor Quintanilla, David Cañas and Javier Oviedo* According to official figures, approximately 2.2 billion people worldwide lack access to drinking water.Despite this panorama, threats to this common good from overexploitation and pollution are increasing. One such threat is the accelerated extraction of lithium in Latin American countries, driven by corporate and state actors to meet the energy transition needs of the global North.Lithium extraction involves enormous water consumption and loss and is essentially water mining.On the continent, the advance of the lithium industry particularly threatens the salt flats and other Andean wetlands of the Gran Atacama region—located in the ecological region of the Puna, on the border of Argentina, Bolivia and Chile—where more than 53 percent of the mineral’s resources (potentially exploitable material) are located.Lithium mining exacerbates the natural water deficit in the area, threatening not only the salt flats, but also the many forms of life that live there. Where does the water used in lithium mining come from?First, it’s necessary to point out that salt flats are aquatic ecosystems located at the bottom of endorheic or closed basins. There, rivers do not flow into the sea but into the interior of the territory, so the water forms lakes or lagoons often accompanied by salt flats due to evaporation.In the salt flats, freshwater and saltwater usually coexist in a delicate balance that allows life to survive.The regions with salt flats, such as the Gran Atacama, are arid or semi-arid, with high evaporation and low rainfall. There we find freshwater aquifers at the foot of the mountains and brine aquifers in the center of the salt flats, both connected and in equilibrium.Brine is basically water with a high salt content, although the lithium mining industry considers it a mineral to justify its exploitation and minimize the water footprint of its activities.In addition to being essential for life, the waters of the salt flats are a heritage resource because they are very old—up to tens of thousands of years—and have been the livelihood of the indigenous people who have inhabited the Puna for thousands of years.When the mining industry moves into a salt flat, it threatens the natural balance and directly affects the relationship between water and the social environment, as well as the relationship between water and other forms of life.To extract lithium from a salt flat, the traditional procedure is to drill the salt flat, pour the brine into large ponds, wait for the water to evaporate so that the lithium concentration increases, send the lithium concentrate to an industrial plant and subject it to chemical treatment to separate the lithium from other salts and finally obtain lithium carbonate or hydroxide: a raw material used mainly in the manufacture of batteries.The continuous and large-scale extraction of brine from saline aquifers alters the natural balance of groundwater. As a result, areas that were previously filled with brine are emptied, causing freshwater from nearby aquifers to move in and occupy those spaces, becoming salinized in the process.The final processes to extract lithium carbonate and separate it from the rest of the compound also require water, which is drawn from surface or underground sources that also supply local communities.Therefore, the water used in lithium mining comes from:Underground freshwater and brine aquifers.Surface sources such as rivers and vegas (land where water accumulates). Therefore, the inherent risk of lithium mining is the overexploitation of these water sources. How much water does lithium mining use?The extraction of lithium by the methods described above involves an enormous consumption and loss of water, which is not returned to the environment because it completely used up, because its properties change, or because it is simply lost through evaporation.According to scientific data, the average water overconsumption in lithium mining is as follows:150 m3 of fresh water used to produce one ton of lithium.350 m3 of brine per ton of lithium.Between 100 and 1000 m3 of water evaporated per ton of lithium produced. To illustrate the loss of water resources in lithium mining, the water lost to evaporation is equivalent to the total water consumption of the population of Antofagasta (166,000 people) for two years. This Chilean city is located 200 km from the Salar de Atacama, where more than 90 percent of the country's lithium reserves are located.In addition to water depletion, lithium mining can also contaminate the resource by producing wastewater containing toxic substances. Our vital relationship with waterUnlike the mining industry, which sees water as just another resource to be exploited, the indigenous communities living in the area have an ancestral connection to the resource on which their economic and productive activities depend, as well as their customs, traditions and worldview.These communities must now confront the pressures on water from the advance of lithium mining, driven by outside interests.But they are doing so with courage, developing processes of defense of water and territory.Let us learn from them to defend a common good without which no way of life is possible.Learn more about the impacts of lithium mining on Andean salt flats in this StoryMap (in Spanish)Watch the recording of the webinar “Evidence of hyperconsumption of water in lithium extraction and production” (in Spanish) *Víctor Quintanilla is AIDA's Content Coordinator; David Cañas and Javier Oviedo are scientific advisors. 

Declaration of a Temporary Reserve Area in the Santurbán Páramo is a victory for the defense of water in Latin America

Civil society organizations celebrate the measure taken by the Colombian Ministry of the Environment, which involves a two year suspension of Canadian company Aris Mining's gold mining project in the páramo.Bogotá, Colombia. The Interamerican Association for Environmental Defense (AIDA), the Institute for Policy Studies (IPS) - Mining and Trade Project, MiningWatch Canada, the Center for International Environmental Law (CIEL) and Common Frontiers Canada celebrate the Colombian Ministry of Environment and Sustainable Development’s (MADS) resolution that declares the western side of the Santurbán massif a temporary renewable natural resource reserve area. This major step strengthens the protection of one of the most emblematic high-altitude Andean wetlands, known as páramo, and its related ecosystems, which are fundamental for climate change adaptation and water security in the region for an estimated 2 million people.Resolution 0221, issued on March 3, 2025 by the Ministry of Environment and Sustainable Development (MADS), delimits and protects an area of 75,344.65 hectares, ensuring  a two year provisional suspension of the Soto Norte gold mining project owned by Canadian company Aris Mining and its Colombian subsidiary, Sociedad Minera de Santander S.A.S. (Minesa), which puts Santurbán at risk. Citing the precautionary principle, the resolution prohibits the granting of “new mining concessions, special exploration and exploitation contracts, (...) as well as new environmental permits or licenses for the exploration or exploitation of minerals” in the area until the necessary technical studies are carried out toward its definitive protection. This resolution does not affect agricultural, livestock or tourism activity in the area.However, we are concerned that the resolution leaves in force the concession contract with Calimineros, which has had a subcontract with Minesa to formalize [its small-scale mining activities] since 2020, and from which Minesa promises to buy and process mineralized material. We encourage the competent authorities to suspend evaluation of its environmental license application and extension of the formalization subcontract, due to potential environmental impacts on Santurbán and because it is effectively part of the Soto Norte project.The páramo and related ecosystems are highly sensitive, recognized for their role in water regulation, carbon capture, and the conservation of endemic biodiversity. The removal of vegetation cover and the fragmentation of ecosystems that mining in Santurbán would generate could affect the ecological balance, biodiversity,  and the provision of ecosystem services essential for life; acidify and reduce the amount of available fresh-water; and break the ecological interconnectivity with other biomes and ecosystems, destroying their capacity to sequester carbon and causing irreparable damage.For these reasons, we appreciate that the resolution seeks to prevent mining development in this highly sensitive and environmentally important area, preventing degradation of the watersheds that arise from Santurbán and preserving the water cycle.Sebastián Abad-Jara, an attorney for AIDA, pointed out that "by protecting Santurbán, Colombia ratifies its commitment to meet global environmental goals in terms of biodiversity, climate and wetlands, and sets a high bar for the governments of other countries where these ecosystems are similarly threatened by mining activity, such as Peru and Ecuador.""We celebrate this declaration as an important first step toward the consolidation of the western side of the Santurbán massif as a permanent reserve area, definitively protecting this important water source, vital for all who depend on it," said Jen Moore, associate fellow at IPS - Mining and Trade Project.Viviana Herrera, Latin America Program Coordinator for MiningWatch Canada, added that "this resolution is the result of the Committee for the Defence of Water and Páramo of Santurbán’s hard work, which has faced harassment and intimidation for its work in defense of the páramo, as well as disinformation campaigns about the supposed harmful effects of the resolution on agricultural activity."AIDA, IPS-Mining and Trade Project, MiningWatch Canada, CIEL and Common Frontiers Canada support the adoption of this protection measure for Santurbán. We also encourage the national and local government to carry out the necessary technical studies for its definitive protection, and to take preventive measures to avoid the cumulative environmental impacts of mining in the area given other projects that already have mining licenses. Furthermore, we reiterate the urgency of adopting measures to protect environment defenders in Colombia who stand up for the páramo.The Santurbán experience provides valuable lessons and should serve as an example to promote legislation for environmental protection in Latin America that focuses on the human right to water and the balance and integrity of fragile ecosystems, such as the páramo and other high-altitude ecosystems.#OurGoldIsWater Press contactsVictor Quintanilla (Mexico), AIDA, [email protected], +5215570522107Jennifer Moore, IPS, [email protected], +12027049011 (prensa IPS)Viviana Herrera, Mining Watch Canada, [email protected], +14389931264Alexandra Colón-Amil, CIEL, [email protected], +12024550253
