Organizing the Network for Environmental Justice in Colombia
The Network for Environmental Justice in Colombia is an effort to coordinate organizations and legal resources for the protection of human rights and the environment.
The Network was founded in 2010 under the coordination of AIDA and with the help of the Latin American Institute for Alternative Society and Law, the Institute for the Study of Peace and Development, the Inter-Ecclesial Commission for Justice and Peace, and the University of Los Andes, the University of Caldas, and Del Rosario University. The network began with 79 participants and now includes more than 500 people and participating organizations.
The Network’s principal objective is to propose solutions to environmental conflicts in Colombia. It also aims to promote the fair and effective use of international and domestic environmental law, in particular, the right to a clean and healthy environment.
What does the network do?
- Facilitates the exchange of knowledge and information to implement legal strategies in precedent-setting cases. One such project was the Mandé Norte Mine, in which several members of the Network developed a legal strategy, resulting in a judicial decision that established Colombia’s need to perform an independent environmental impact assessment. Most importantly, the decision also mandated that developers obtain the consent of indigenous peoples before moving forward with any projects in their territory.
- Promotes organizational alliances, garners support, and connects legal work in defense of the environment.
- Organizes conversations, forums, and constructive debates on environmental issues.
- Provides access to legal resources including laws, court decisions, articles and legal analysis, and facilitates communication through its website and social media channels.
- Advises law students through the AIDA volunteer program. In doing so, the Network strengthens the capacity for environmental law in Colombia.

Community of La Oroya wins landmark ruling to stop environmental damage in Latin America
After more than 20 years, the residents of the town of La Oroya in the Peruvian Andes have found justice, opening a major new avenue for protecting a healthy environment throughout the continent. In an unprecedented decision, the Inter-American Court of Human Rights found Peru guilty of violating their human rights by failing to act in a timely and effective manner to protect them from extreme levels of pollution from a metallurgical complex that has operated in their community for nearly 90 years. "Twenty years ago, when this struggle began, I carried my banner saying that children's health is worth more than gold," recalls Don Pablo, a resident of La Oroya. "We never gave up, and now I am very happy with the Court's decision.” La Oroya is located in the central mountain range of Peru, in the department of Junín, approximately 176 km from Lima. In 1992, the US company Cerro de Pasco Cooper Corporation installed the La Oroya Metallurgical Complex to process ore concentrates. The complex was nationalized in 1974 and operated by the state until 1997, when it was taken over by Doe Run Peru, which operated it until 2009. For generations, the inhabitants of La Oroya have inhaled toxic substances that pose serious risks to human health. Heavy metal contamination has invaded their respiratory system, traveled through their bloodstream, and been imperceptibly deposited in several of their vital organs. Most of those affected had lead levels above those recommended by the World Health Organization, and in some cases higher levels of arsenic and cadmium, in addition to stress, anxiety, skin disorders, stomach problems, chronic headaches, and respiratory or cardiac problems. In 1997, AIDA became involved in defending the rights of the La Oroya community. Our publication La Oroya No Espera (La Oroya Cannot Wait), published in 2002, helped bring the gravity of the situation to international attention. In 2006, in the absence of effective responses in Peru, we joined an international coalition of organizations in filing a complaint against Peru before the Inter-American Commission on Human Rights. In 2021, the Commission established the responsibility of the Peruvian government in the case and referred it to the Inter-American Court. In October 2022, more than 16 years after the complaint was filed, the victims presented the case to the Court in a public hearing, represented by AIDA and the Asociación Pro Derechos Humanos (APRODEH), with the support of Earthjustice. Since 2009, when the metallurgical complex ceased operations due to Doe Run Peru's financial crisis, the levels of heavy metal contamination have not been reduced to acceptable levels. Nor has the situation of those affected improved significantly in recent years. Although the Peruvian government has known since 2009 that all children living near the complex are suffering from lead poisoning, it has not provided them with adequate medical care. But there is no deadline that will not be met. On March 22, the Inter-American Court of Human Rights gave a powerful response to more than two decades of seeking justice. The Court found that Peru was guilty of violating the rights to a healthy environment, health, personal integrity, life with dignity, access to information, political participation, judicial guarantees, and judicial protection of the 80 people involved in the case; of violating the rights of the children of 57 victims; and of violating the right to life of two others. "This is the first judgment that recognizes the international responsibility of a state for violating the right to a healthy environment and other related rights," says Rosa Peña, AIDA Senior Attorney.

These include the prosecution and punishment of those who harassed the residents for their environmental defense work; the preparation of a remediation plan for air, soil, and water contamination; the provision of free and specialized medical care to the victims, as well as to other residents with symptoms and illnesses related to mining and metallurgical activities; the updating of air quality regulations to ensure the protection of the environment and human health; the provision of monetary compensation to the victims; and the creation of an air, water, and soil quality monitoring system. It also ordered that the operations of the La Oroya Metallurgical Complex—which was transferred to the workers of Doe Run Peru as part of the company's liquidation—comply with international environmental standards and prevent and mitigate damage to the environment and human health. The Court's decision is not only a unique opportunity to restore the dignity and rights of the people of La Oroya. Its scope extends beyond the Peruvian context, making it an important precedent in Latin America for the protection of the right to a healthy environment and for adequate state oversight of corporate activities. Among other things, the Court established the obligations of states to regulate, monitor and control air and water quality, to identify sources of pollution, and to implement plans to enforce air and water quality standards. The Court held that in order to establish state liability for environmental damage, it is sufficient to show that the state, despite being aware of the existence of high levels of pollution, failed to take adequate measures and thus allowed the pollution to continue, thereby posing a significant risk to human health. In light of the judgment, states must prevent human rights abuses by public and private enterprises. Businesses, for their part, must prevent their activities from causing or contributing to human rights abuses and take steps to remedy such abuses. Defending the right to a healthy environment has been part of AIDA's history since our inception and has always been a collective effort. We celebrate and recognize all the people who, from different sectors, roles and capacities, made possible the historic result of the La Oroya case. With renewed vigor, we will work for the proper implementation of the judgment and for the establishment of new important precedents that will guarantee in practice the universal right to a healthy environment in the region.

Celebrating the appointment of Astrid Puentes Riaño as UN Special Rapporteur
On April 5, during its 55th session, the United Nations Human Rights Council appointed Astrid Puentes Riaño as the new UN Special Rapporteur on the human right to a clean, healthy and sustainable environment. For 18 years, as co-executive director of AIDA, Puentes Riaño led efforts across Latin America to uphold the right to a healthy environment and protect affected communities from environmental harms. Her strategic vision and powerful command of public interest law and advocacy has left a lasting contribution on both AIDA and the larger movement for climate justice in the region. She will be the first woman and first person from the Global South, and the third Special Rapporteur, to assume this important mandate. Gladys Martínez de Lemos, executive director of AIDA, expressed: “Astrid’s career has long been focused on protecting the right to a healthy environment, as a leader of the movement in Latin America. Her new role as Special Rapporteur is a natural and well-deserved progression, and we know her continued leadership on the international stage will strengthen efforts towards climate and environmental justice around the world.” In May Puentes Riaño will replace David R. Boyd, who made tremendous strides as Rapporteur, including the UN recognition of a clean, healthy and sustainable environment as a universal human right. Boyd is a former member of AIDA’s Board of Directors. The Special Rapporteur’s mandate is an essential nexus of environmental and human rights defense, as it exists to: examine human rights obligations linked to the enjoyment of a safe, clean, healthy and sustainable environment; promote best practice in the use of human rights in policy making; identify challenges and obstacles to the global recognition and implementation of the right to a safe, clean, healthy and sustainable environment; and conducting country visits and responding to human rights violations.

The Kawésqar people and the defense of their "maritorio" in Chile
By Liliana Ávila and Cristina Lux* A little over a month ago, the community Kawésqar Grupos Familiares Nómades del Mar sent us a very special invitation. The appointment was near the sea, near their territory, or more precisely, near their "maritorio", a place of islands, islets and archipelagos. There, the borders between sea and land are blurred and the trees grow sideways, adapted to the strong winds. The maritorio is a concept and also a way of inhabiting and understanding the world. It evokes the image of "territory", but seen from and in the sea. As a concept, it emerged in the context of what is known as nisology, or the study of islands. The place we visited is located in the fjords of Magallanes, the southernmost region of Chile, about two hours from Punta Arenas, the regional capital. The Kawésqar people tell us that less than a century ago, this maritorio was their home. There, their grandfathers and grandmothers sailed among the fjords, built their canoes, fished and dived. They went into the icy sea without special neoprene suits, protected with sea lion oil, and there they learned the secrets that its depths held. In the midst of fjords, winds and intense climates, these people developed their own systems of thought and life. But the lives of the Kawésqar have changed radically in recent decades. They tell us so. The vast territory that previous generations inhabited for centuries is now enclosed. The process of eradication has been accompanied by the commercialization of the land, the creation of extensive pastures and, more recently, the development and expansion of the salmon farming industry. Industrial salmon production has serious and lasting impacts on marine ecosystems. The communities of Kawésqar are well aware of this. Salmon is an exotic and carnivorous species for Chile, raised in huge farms: hectares of cages in the sea. The introduction of exotic species (which threaten native species), the excessive use of antibiotics, salmon escapes, the generation of waste, the treatment of large quantities of dead salmon, the excessive discharge of organic matter into the sea, and the generation of anaerobic environments (total or partial loss of oxygen necessary for life to thrive) are just some of the impacts of salmon farming in Chile. These impacts not only accumulate in the waters and on the seabed, but also penetrate the lives of the Kawésqar communities. The maritorio that their grandfathers and grandmothers sailed is now a desecrated space. The processes of reconstructing their identity, the appropriation of sacred places and the rites that are part of their collective memory have been affected by the development of an industry that sees the sea only as a space of economic exploitation and not as the sacred place where, in the not so distant past, men and women developed their worldviews and ways of life. Despite everything, the Kawésqar are a living people who meet, who gather around the sea and discuss strategies to rebuild their cultural fabric. They also come together to honor their grandfathers and grandmothers, to activate the genetic memory that connects them to the sea, to dive into its waters and fight for a salmon-free sea and for a country that recognizes the cultural diversity that runs through its history. We also connect with the legacy of the Kawésqar. Swimming with people from the community in these seas that have been navigated for thousands of years allowed us to look out a window that blurs the present and shows us alternatives. A present that allows life and coexistence with the sea, its ecosystems and its balance. Their struggle— supported by AIDA, the NGO FIMA, Greenpeace and many other organizations— has borne fruit. It has highlighted the impact of salmon farming in Chile and the need to end our dependence on it. But the challenges are still enormous. Salmon farming continues to ravage the seas inside and outside protected areas, in the most remote areas of Patagonia, occupying spaces that were once shared by all the peoples and creatures that inhabited the territory. Meanwhile, the people of Kawésqar continue to travel through their territory —rewarded and lived in and from the sea— identifying and recomposing their history, swimming in the waters that surround them. They do not lose hope of returning to their sea; they to continue to exist in it. *Liliana Avila is coordinator of AIDA's Human Rights and Environment Program; Cristina Lux is an attorney with the Climate Program.
