Liliana Ávila /AIDAMayan women’s struggle before the Inter-American Development Bank in Guatemala
Mayan communities succeeded in getting the IDB Invest to develop a responsible exit plan after withdrawing its financing for two hydroelectric projects that negatively impacted ecosystems and the livelihoods of indigenous peoples, especially women, in the micro-region of Yichk'isis (Ixquisis).
In the struggle to defend their water, territory and way of life, indigenous Mayan communities in the Yichk'isis (Ixquisis) micro-region of northern Guatemala convinced the Inter-American Development Bank Group to withdraw its financing of two hydroelectric dams whose implementation violated their rights. The decision was also significant in that the IDB, for the first time, designed a responsible exit plan.
That historic advance was the result of the complaint that the communities filed in August 2018—with the support of AIDA, the Plurinational Ancestral Government of the Akateko, Chuj, and Q'anjob'al Native Nations, and the International Platform against Impunity. The complaint was filed with the Independent Consultation and Investigation Mechanism (MICI), the IDB Group's accountability office.
In resolving the case in September 2021, the MICI concluded that IDB Invest failed to comply with its own operational policies and safeguards, in the framework of the financing granted to the company Energía y Renovación S.A. for the implementation of the San Mateo and San Andrés hydroelectric projects.

In the mountains of Northwestern Guatemala, near the border with Mexico, the land is rich and fertile. Several important rivers and many other water sources feed the soil.
The residents of these mountains, many indigenous women of Mayan descent, have long depended on the waters to nourish them, to provide them with fish, as well as for agriculture, sanitation, and cooking.
But the construction of the San Mateo and San Andres dams has caused water scarcity and the contamination of rivers and other natural resources long cherished by the communities.
The near lack of water has also drastically reduced harvests, lessening the income gained from selling corn, wheat, beans, coffee, sugar cane and other products in the market. As a result, the conditions of poverty in the area have deepened.
And the risk situation is profound, particularly for women, who have played a very important role in the defense of water and territory threatened by hydroelectric projects, and are therefore victims of intimidation and stigmatization.
As guardians of their land and water, they have come to its defense and they’ll continue to prevent environmental deterioration from further harming their families.

Plan Colombia Aerial Herbicide Spraying Not Proved Safe for the Environment – Released to US Congress
For Immediate Release February 14, 2007 CONTACTS: Anna Cederstav, AIDA (510) 550-6700 [email protected] Astrid Puentes, AIDA (5255) 52120141 [email protected] PLAN COLOMBIA AERIAL HERBICIDE SPRAYING NOT PROVEN SAFE FOR THE ENVIRONMENT Critique of recent studies by international environmental NGO released to Congress today OAKLAND, CA, MÉXICO, D.F. - In December, the Colombian government violated a bilateral accord with Ecuador by spraying a mixture of herbicides intended to destroy coca crops within 10 kilometers of the Ecuadorian border. To justify the spraying, Colombia relied on studies by a team from the Inter-American Drug Abuse Control Commission (CICAD) of the Organization of American States (OAS), claiming that the spray mixture is safe. However, an independent review of CICAD’s recent studies, released to members of the U.S. Congress today, shows that the pesticide mixture being sprayed has not, in fact, been proven safe for the environment, and that Ecuador has substantial cause to oppose the spraying. According to the Interamerican Association for Environmental Defense (AIDA), the first CICAD Environmental and Human Health Assessment of the Aerial Spray Program for Coca and Poppy Control in Colombia, released in 2005, did not assess many of the greatest potential ecological and human health risks posed by the aerial eradication program in Colombia. Because of these omissions and the potential environmental risk of the spraying, the U.S. Congress requested further studies to better assess whether the mixture is truly safe for the environment. Preliminary results from the follow-up studies, released in August 2006, show that the mixture is indeed potentially harmful to the environment, and particularly to amphibians – the spray mixture killed 50 percent of the amphibians exposed in less than 96 hours. According to Earthjustice scientist and AIDA’s Program Director Anna Cederstav, “Contrary to what is argued by the government, this study shows sufficient cause for concern to suspend the sprayings due to potential environmental impacts, especially considering that Colombia has the second highest amphibian biodiversity in the world and the most threatened amphibian species.” Many other key questions about the environmental impacts of the spraying also remain unanswered, despite the U.S. Congressional mandate to conduct the studies. For example, the State Department has not provided adequate information about the location of and risk to sensitive water bodies and has done nothing to address whether other threatened species are likely to be harmed. Without these determinations, the claim by the Colombian government that it is safe to spray along the Ecuadorian border is misinformed. “Given the number of unanswered questions about the safety of the spraying, and considering the precautionary principle and the international obligation not to cause impacts to the territories of other States, the Colombian government should halt spraying immediately, and instead implement more effective and environmentally safe alternatives for coca eradication,” said Astrid Puentes, AIDA’s Legal Director.

Read moreAIDA Calls for Alternative Development Programs in Colombia
AIDA Report Highlights Need for Alternative Programs in Colombia After six years of spraying herbicides over large areas of the Colombian countryside under "Plan Colombia," the aerial spraying program has failed to meet the goal of eliminating 50 percent of illicit crops in this country. Despite an investment of nearly US$1.2 billion, and the spraying of more than four times the initial area of coca crops, coca cultivation in Colombia continues, at nearly the same levels as when the program originated. Meanwhile, the spraying continues to cause severe social impacts and pose unknown environmental risk. AIDA has prepared a report analyzing some of the participatory, sustainable, alternative development programs that have proven more effective than aerial spraying. The report recommends that the U.S. and Colombian governments reevaluate the current policy and substantially increase support for such alternatives. The report highlights the need for a comprehensive approach to the problem of illegal crop cultivation, with a strategy that addresses the root-causes of the problem. The report provides detailed information and an analysis of five programs implemented by different actors, all of which can serve as models or provide lessons learned for new programs. Although improvements can still be made, alternative development programs have yielded concrete, positive results and have been far more cost-effective than the spraying program.
