Cajamarca is a town in the mountains of central Colombia, often referred to as "Colombia’s pantry” due to its great agricultural production. In addition to fertile lands, fed by rivers and 161 freshwater springs, the municipality features panoramic views of gorges and cloud forests. The main economic activities of its population—agriculture and tourism—depend on the health of these natural environments.
The fertile lands of Cajamarca are also rich in minerals, for which AngloGold Ashanti has descended on the region. The international mining conglomerate seeks to develop one of the world’s largest open-pit gold mines in the area. Open-pit mining is particularly damaging to the environment as extracting the metal involves razing green areas and generating huge amounts of potentially toxic waste
The project, appropriately named La Colosa, would be the second largest of its kind in Latin America and the first open-pit gold mine in Colombia. The toxic elements that an operation of that magnitude would leave behind could contaminate the soil, air, rivers and groundwater.
In addition, storms, earthquakes, or simple design errors could easily cause the dams storing the toxic mining waste to rupture. The collapse of similar tailings dams in Peru and Brazil in recent years has caused catastrophic social and environmental consequences.
On March 26, 2017, in a popular referendum, 98 percent of the voters of Cajamarca said “No” to mining in their territory, effectively rejecting the La Colosa project. AIDA is proud to have contributed to that initiative. But even with this promising citizen-led victory, much work remains.

Did you know coral reefs produce medicine?
“How can coral reefs contribute to modern medicine?” I wondered as I spoke to a group of doctors and nurses working on liver disease in Mexico. My uncle is part of the organization (Amihigo) and has long been interested in my work as a marine attorney with AIDA. When I got back from the meeting, the information I found backed up our discussion and clarified the link between our two worlds: coral reefs are natural, underwater pharmacies. The plants and animals living in reefs have developed chemical compounds to protect themselves against predators, fight diseases, and prevent the excessive growth of competing organisms. Corals have been recognized as an important source of new drugs to treat cancer, arthritis, Alzheimer’s, bacterial infections, viruses and heart disease, among other serious illnesses, according to the US-based National Ocean Service. The pharmaceutical industry has found corals provide value in the development of new products. Certain corals, for example, stimulate the welding of broken bones. Components of a Caribbean sponge allow for the creation of Zidovudina, a medicine used to treat HIV. Despite these discoveries, the medical use of coral reefs is considered underdeveloped. As an environmental attorney, what I take away from this realization is that if coral reefs are not effectively preserved, their great potential for modern medicine will never be fully realized. It’s a real threat. Studies estimate that 30 percent of the world’s reefs are already seriously damaged, and that 60 percent could disappear by 2030 due to water pollution, destructive fishing methods, overfishing, and other unsustainable human activities. Compounding these is the growing threat of climate change. Several Latin American nations are blessed with large areas of coral reefs that provide environmental and social benefits. But many don’t do enough to protect that wealth. Mexico’s coastline extends for more than 11 thousand kilometers, featuring 5,100 square kilometers of islands, reefs and cays. Its coral reefs span six major regions: the Gulf of California and the Western Mexican Pacific Coast, the Revillagigedo Archipelago, the Marias Islands, the South Pacific Coast, the Gulf of Mexico Reef Corridor and the Campeche Bank, and the Mexican Caribbean. The loss and degradation of these rich reef systems is a growing problem across the country. Unsustainable and poorly planned urban and coastal development is causing sedimentation and pollution, resulting in the growth of microalgae that rob light and oxygen, effectively suffocating the corals. In the Veracruz Reef System, the largest in the Gulf of Mexico, the expansion of the Port of Veracruz is doing just that. To protect reefs, it’s imperative that governments act with caution when approving land use in urban development plans to avoid damaging coastal wetlands (lagoons, bays, mangroves, coastal dunes and sea grasses, among others), and that they adopt adequate measures for wastewater treatment. The protection and restoration of coral reefs and coastal wetlands should be prioritized over economic interests and short-term economic benefits. Effective reef conservation can also be supported by good regulation practices. Measures to protect key species such as the parrotfish from overfishing, for example, would go a long was to preserving the health of coral reefs. And we now know that the health of those reefs is directly tied to our own. It’s important the health industry—from doctors and patients to scientists and pharmacists—join the call to conserve our coral reefs, natural medicine banks that can help guarantee our rights to a dignified life and a healthy environment.

Organizations call for support for communities affected by Colombia’s Hidroituango dam
Communities affected by the Hidroituango dam have denounced the murder of two of their members over the past few days. In addition, a recent obstruction in one of the dam’s tunnels means the dam is at risk of overflowing, which could cause an avalanche of mud and debris. Allies are calling on authorities to investigate the harms to local communities and provide adequate support for those affected. Two members of Movimiento Ríos Vivos Antioquia, the coalition of communities affected by Colombia’s Hidroituango Dam, have been murdered in the last several days. Hugo Albeiro George Pérez and Luis Alberto Torres Montoya were murdered on May 2 and 8, respectively, according to statements from Ríos Vivos. Members of the movement have also suffered threats, intimidation, and human rights violations due to their defense of their land and the Cauca River. At the same time, residents of towns downstream from the dam are living in fear and uncertainty this week, faced with a potential environmental catastrophe. The imminent danger is caused by an obstruction in one of the dam’s diversion tunnels that, by interrupting the flow of the Cauca River, could cause the dam to overflow with such force that it would release not just water but an avalanche of mud and debris. The Interamerican Association for Environmental Defense (AIDA), the Center for International Environmental Law (CIEL), and the International Accountability Project (IAP) express our support for Movimiento Ríos Vivos of Antioquia and the communities affected by the Hidroituango Dam in Colombia. We demand that Colombia’s environmental authorities find and punish those responsible for the murders, as well as investigate the ongoing damages caused by the dam’s construction. We also call on the national government to promptly and adequately provide support for affected families. Hidroituango, expected to become Colombia’s largest dam, will affect 12 municipalities, changing the lives of thousand of families that depend directly on the river. The project has received funding from IDB Invest, the private-sector branch of the Inter-American Development Bank. Press contact: Víctor Quintanilla, AIDA, +521 5570522107, [email protected]
