Preserving the legacy of the Sierra Nevada de Santa Marta, Heart of the World
Rising abruptly from Colombia’s Caribbean coast, the Sierra Nevada de Santa Marta reaches 5,775 meters (18,946 ft.) at its highest points, the peaks of Bolívar and Colón. It is the highest coastal mountain system in the world, a place where indigenous knowledge and nature’s own wisdom converge.
The sheer changes in elevation create a wide variety of ecosystems within a small area, where the diversity of plant and animal life creates a unique exuberant region. The melting snows of the highest peaks form rivers and lakes, whose freshwater flows down steep slopes to the tropical sea at the base of the mountains.
The indigenous Arhuaco, Kogi, Wiwa, and Kankuamo people protect and care for this natural treasure with an authority they have inherited from their ancestors. According to their worldview the land is sacred and shared in divine communion between humans, animals, plants, rivers, mountains, and the spirts of their ancestors.
Despite this ancestral inheritance, development projects proposed for the region have failed to take the opinions of these indigenous groups into consideration. The Sierra Nevada de Santa Marta is currently threatened by 251 mineral concessions, hydroelectric projects, agriculture, urban sprawl, and infrastructure projects.
Many of these concessions were granted without the prior consultation of the indigenous communities, which represents a persistent and systematic violation of their rights.
Mining, which implies the contamination and erosion of watersheds, threatens the health of more than 30 rivers that flow out of the Sierra; these are the water sources of the departments of Magdalena, César, and La Guajira.
These threats have brought this natural paradise to the brink of no return. With it, would go the traditional lives of its indigenous inhabitants, who are dependent on the health of their land and the sacred sites it contains.
The Sierra hosts the archaeological site of la Ciudad Perdida, the Lost City, known as Teyuna, the cradle of Tayrona civilization. According to tradition, it is the source from which all nature was born—the living heart of the world.
The four guardian cultures of the Sierra are uninterested in allowing this natural and cultural legacy to disappear.

How much water is used to produce energy?
Water and energy go hand in hand. Processes such as gas extraction, oil refining, and hydroelectric power plant operations all require water. Thus, as energy demand increases, so does the need for water to generate it.This leads to environmental and social impacts, including the depletion of water sources and the pollution of rivers, lakes, and other bodies of water.Understanding the connection between water and energy production gives us a broader perspective on what our water consumption entails.Conserving water also means reducing our energy consumption, exploring more sustainable energy generation options, and demanding that energy be produced in a clean and fair manner. The water footprint of energyWater is essential for energy production. But not all sources consume the same amount of water, so their environmental impact varies. To generate 1 megawatt—enough to power 1,000 homes for one hour—here is how many liters of water are consumed by different sources of electricity:Coal-fired power plant: 2,079 Gas-fired power plant: 1,701 Hydroelectric: 0.0567 Nuclear: 2,646Geothermal: 1,134Solar: 45Wind: 0 But water use goes beyond that. In addition to electricity generation, the energy sector uses freshwater—with various socio-environmental impacts—in its various production processes:Fuel extraction and productionFuel refining and processingFuel transportationEmissions control and waste management Conventional thermoelectric power plantsIn these plants, water is heated to high temperatures—by burning coal, gas, or oil—to produce steam, which drives turbines to generate electricity.Water is also used in thermal power plants to cool the power-generating units. Hydroelectric power plantsThey use the force of water to drive turbines that generate electricity. By damming or diverting the natural flow of rivers, streams, and lakes, they fragment habitats, leading to the displacement and decline of species. They also impact water quality.Furthermore, they cause the forced displacement of communities living near water sources and who depend on them. Fuel extraction and productionWater is used in coal mining and in drilling wells for oil and gas. In many cases, these processes generate wastewater.Water is also needed to refine oil and gas before they can be used as fuels. Coal miningIn addition to using water to extract the mineral, it can be used—along with chemicals—to remove sulfur and impurities before combustion. Coal mining using explosives generates debris that can contaminate local water sources and even block them. Coal can be transported to the power plant using a method that pumps the finely ground coal mixed with water through pipes. Hydraulic fracturing (fracking)In this technique, a mixture consisting of more than 90% water, along with chemicals and sand, is injected at high pressure into underground rock formations to fracture them and access the oil or gas they contain.The wastewater from this mixture remains underground and can contaminate the groundwater that feeds nearby aquifers. Renewable energySolar photovoltaic and wind power do not use water to operate, but they require supplies and materials whose production requires water.A notable example is lithium, which is used to manufacture the batteries that store the energy generated by these sources. Its extraction involves massive water consumption from salt flats, one of its primary sources:2,000 liters of water for every ton of lithium produced in evaporation ponds.Water is used to extract lithium carbonate and separate it from the remaining compound.Water is lost during brine pumping. Understanding how much water is needed to generate the energy we use gives us a broader perspective on the water our energy consumption entails.Reducing our energy needs and promoting sustainable and equitable energy production are also ways to conserve water.

Closure and Responsible Exit
A requirement for environmental and climate justice in Latin America No natural resource (material or energy) extraction project lasts forever. Its useful life is subject to many variables, including endogenous factors -such as the amount of resource reserves or the extraction rate- and exogenous factors -such as decisions to address the climate crisis, the decrease in demand, financial problems, etc.- that condition the moment in which the project must close or the moment in which an actor in its value and supply chain must leave. Regardless of the length of the project's useful life or how it may be affected, a responsible closure process with the natural environment and society must be contemplated, which must be desired and promoted by all the stakeholders involved.This issue is even more relevant in the context of the climate crisis we are experiencing, which makes it urgent to implement measures to manage it in the short, medium and long term. Many of the actions required to meet greenhouse gas (GHG) mitigation targets are related to energy transition, which implies, in general terms, at least two things: 1) the substitution of fossil fuel extraction and use projects and 2) the promotion of low-emission renewable energies, which are associated with mineral extraction. In both scenarios, closure and exit issues are of great importance.In both extraction and generation projects, the role of their promoters, whether public or private, is essential. Likewise, the obligation of supervision and oversight of the States is very important for the protection and guarantee of the rights of those who may be affected. On occasions, the responsibility of the exit includes other key actors that are part of the value and supply chains of the projects: investors, insurers, distributors and buyers, among others.In Latin America, there have been important advances in regulating aspects related to the authorization, start-up and implementation of mining and energy projects. In these phases, environmental principles such as prevention and precaution, as well as rights such as prior consultation and free, prior and informed consent, and access rights, have played a crucial role in determining the viability and progress of projects, as well as in protecting and guaranteeing the rights of communities in the region. However, experience has shown that there are significant challenges for the closure and exit processes to be responsible with the ecosystems and communities involved. Indeed, the lack of a closure process, as well as the lack of clarity about the obligations surrounding the social transition processes and overcoming the conditions of economic dependence, are complex obstacles that can exacerbate environmental and social impacts. This report arises from the idea of proposing approaches based on law and science to address the closure and responsible exit of projects. To this end, we at the Interamerican Association for Environmental Defense (AIDA), in the period 2022-2024, interviewed various stakeholders and systematized 12 cases that exemplify the problematic situation of multiple fossil fuel extraction, mineral and power generation projects, which are in the closure phase or in exit processes in different countries of the region. These cases highlight the current challenges and legal, technical and administrative gaps regarding closure and exit in specific contexts.With this publication, we seek to provide answers to the following questions: what is meant by project closure and exit, what is the basis for closure and exit obligations under international law, what should closure and exit look like, who should be involved in these processes, and how should the social, environmental, economic and human rights challenges and impacts that arise from them be addressed?

When environmental defenders in Latin America take the stage at key international forums
By Víctor Quintanilla and Mayela Sánchez García* The voices of communities across Latin America and the Caribbean are powerful, especially when they call for environmental protection amid multiple, growing threats.Often, this demand falls on deaf ears among those who deliver justice at the national or local level.This trend makes it necessary to turn to complementary avenues of international justice.One such platform is provided by the Inter-American Commission on Human Rights (IACHR), an international body with a critical mandate: the promotion and protection of human rights on the continent.As an organization driven by the mission of guaranteeing the right to a healthy environment in Latin America and the Caribbean, the IACHR serves as a key forum for highlighting environmental issues that affect human rights in the region. We do this in alliance with communities and partner organizations. This allows the voices of local communities to be heard by an international body capable of urging the continent’s governments to change their practices and strengthen their standards for protecting populations affected by environmental degradation. Testimonies calling for a responsible phase-out of fossil fuelsBringing the voices of communities before the IACHR is also an opportunity to highlight regional patterns of risk and human rights violations.So it was on March 10, when representatives from communities in Colombia, Chile, Ecuador, and the Dominican Republic testified before the Commission about how decades of fossil fuel extraction and use have seriously violated human rights such as the right to a healthy environment, the right to health, and the right to access information and participate in environmental matters."Our region doesn’t just need to decarbonize its energy system; it also needs to address the historical injustice that our communities have endured," said Yaneth Ortiz, a representative of the Wayuu indigenous people of La Guajira, a region in northern Colombia that has been severely impacted by the operations of the Carbones del Cerrejón mining project.Their messages were heard by the IACHR during a public hearing titled "Human rights situation related to fossil fuel extraction," held as part of its 195th Period of Sessions.Community representatives also noted that, in the current context of the energy transition, these violations and risks have become more severe."Our children are getting sick in their own schools. Despite all this, there are no clear parties to blame and no structural solutions… For us, this decarbonization process [in Chile] has been insufficient and lacking in transparency," said Katta Alonso, speaking on behalf of the Chilean organization Mujeres en Zonas de Sacrificio en Resistencia. The local experiences shared highlighted the urgency of implementing just transitions, which entail the responsible phase-out of fossil fuel projects throughout the region.Meanwhile, Juan Bay, president of the Waorani Nationality of Ecuador (NAWE), stated: "We have not been consulted in a prior, free, and informed manner regarding oil exploration on our territory, nor regarding the establishment of the protected area. We now demand that our rights be respected in the process of closing down oil operations and in the environmental and social remediation."AIDA requested the hearing in collaboration with the communities and partner organizations. "We explained the risks and human rights violations faced by various communities in the context of the closure and irresponsible exit of coal, gas, and oil extraction and combustion projects," explains Rosa Peña, AIDA’s attorney.The Commission views the purpose of these hearings as gathering information on human rights issues in specific countries or regionally, in order to issue recommendations to governments aimed at ensuring respect for and the enjoyment of human rights.Before each session, it receives a huge number of requests to address various human rights issues across the continent during the hearings—issues that go beyond just the environment or climate."This is how we got here, after convincing the Commission of the importance of approaching this issue from a human rights perspective and of listening to the communities," says Liliana Ávila, director of AIDA’s Human Rights and Environment Program.Over the years, AIDA has developed significant expertise and leadership in successfully bringing cases before the Inter-American Commission on Human Rights (IACHR) and the Inter-American Court of Human Rights—the two pillars of the Inter-American Human Rights System, a mechanism of the Organization of American States—to achieve regional impact in the protection of a healthy environment, in partnership with local communities. Voices against the damage caused by illegal miningAlso, during the 195th Period of Sessions of the IACHR, we participated in the ex officio hearing titled "Impacts of illegal mining on economic, social, cultural and environmental rights," convened by the Commission itself.Our contribution joined other voices in highlighting why this activity is now one of the most alarming phenomena on the continent, given its severe impact on ecosystems and human rights. In Latin America, gold mining fuels illegal extraction that violates numerous rights, primarily those of indigenous peoples and traditional communities. At the hearing, we proposed relevant measures to the Commission to address the issue from a regional perspective.At AIDA, we seek to amplify the strength of local communities and their people, bringing their wisdom to decision-making forums with the potential to transform realities and build a better future for the continent. *Víctor Quintanilla-Sangüeza is AIDA’s Content Coordinator, and Mayela Sánchez García is the organization’s digital community specialist.
