Known as an “ecological treasure house,” the Sierra La Laguna Biosphere Reserve at the southern tip of Baja California will not be spoiled by toxic mine waste, thanks in part to AIDA’s advocacy.
The reserve was once an island, so it’s home to rare plant and animal species. Canyons, swimming holes, and hot springs can be found in its granite mountain range and lowland tropical forests.
Thanks to AIDA and our partners in Mexico, the Mexican government denied an environmental permit for the Paredones Amarillos gold mine, halting the project for the time being. To protect the biosphere reserve, AIDA helped educate community groups and decision makers about the mine's risks. This helped to build the political momentum necessary for the government to deny the permit.
To extract gold from the mountains, the Canadian company Vista Gold proposed to carve out huge quantities of rock—each ton containing a mere gram of gold–-grind it into sludge, and treated it with cyanide. The company planned to dump massive amounts of toxic waste (called “tailings”) behind a dam intended to store it forever. Unfortunately, tailings dams can break for various reasons, as happened at Bolivia’s Porco mine in 1996. When that dam collapsed, more than a quarter million metric tons of tailings flooded the river and contaminated 500 miles (800 km) of waterways in Bolivia, Argentina and Paraguay.
The mine could also cause acid mine drainage. When sulfur-containing rocks are exposed to air and water, sulfuric acid forms, which causes toxic heavy metals to dissolve and drain into the watershed. The risk of acid mine drainage in Sierra La Laguna was significant and the human and environmental cost would have been tremendous: thousands of people and countless wildlife in the reserve rely on its water for survival.
Depleting freshwater is a further threat because mines use tremendous quantities of water. Owing to the scarcity of water in the reserve, Vista Gold proposed to build a plant on the Pacific coast to remove salt from sea water in a highly energy-intensive process, and then pump the water 45 km to the mine site. The desalination plant posed a threat to the endangered leatherback sea turtle.
Singly and together, the mine’s impacts would have devastated a rare jewel, a unique and lush paradise worth saving for future generations.

International Ocean Conference ends with High Seas Treaty on verge of entry into force
Nice, . The 3rd UN Ocean Conference is ending today with a historic step towards ensuring greater High Seas protection. With 19 additional countries depositing their ratifications, the total number of that count toward the High Seas Treaty’s entry into force has now reached 50. Only 10 more are needed to cross the critical 60-country threshold that would trigger the Treaty’s coming into effect.Several countries have already indicated their intent to deposit their ratification instruments at the UN very soon. There is no obligation for them to wait for the UNGA meeting in September, which could mean the Treaty’s entry into force could be activated in the coming weeks."The journey towards a high seas treaty has been nearly as long as the great migrations of whales, sharks and turtles but the wave of new ratifications at the UN Ocean Conference shows we are in the final straight," said Matthew Collis, Senior Director of Policy at the International Fund for Animal Welfare.In addition to the boost in ratifications, the number of countries g the Treaty also surged. An extra 20 countries added their signatures during the week, bringing the total number to 136. This is an encouraging sign, as widespread ratification will be crucial to ensuring the Treaty’s full effectiveness.Rebecca Hubbard, Director of the High Seas Alliance, emphasized the urgency to maintain momentum: "We must keep our foot on the #RaceForRatification accelerator. The Treaty’s power lies in the number of countries that , so while we celebrate this incredible progress, we urge all remaining nations to ratify without delay and help drive this Treaty past the first 60 to make it a truly global force for ocean protection."Around 60 heads of state and government attended the meeting reflecting a significant high level attention for the plight of the ocean. The momentum on High Seas Treaty ratification showed what is possible when the world comes together with urgency and purpose.“This is a landmark moment to safeguard the ocean as our greater common good, an opportunity to achieve equity and justice for all nations, and to empower regions, such as Latin America, in defining actions that can shape a fair and sustainable future for all,” said María José González-Bernat, Co-Director of Ecosystems Program of the Interamerican Association for Environmental Defense (AIDA).Attention is now also turning to how the Treaty will be implemented once it enters into force. Several major announcements were made earlier in the week including the re-launch of the High Ambition Coalition for BBNJ and the €10 million that has been made available through the EU’s €40 million Global Ocean Programme to provide technical assistance to developing countries for both ratification and implementation. Private philanthropy also stepped up with the Minderoo Foundation pledging an additional USD6.5 million to High Seas protection, and funding was confirmed to a secretariat for the First Movers initiative, which will help advance early proposals for High Seas marine protected areas.Focus is intensifying on building strong bodies and processes under the Treaty to ensure it functions effectively as well as identifying critical High Seas sites for protection once the Treaty is operational through an ongoing Preparatory Commission process at the UN. Efforts to build the case for High Seas MPA proposals submissions under the Treaty were also showcased at the Conference, profiling a number of areas including the Salas y Gomez and Nazca Ridges, the Lord Howe Rise and South Tasman Sea, the West Indian Ocean Sub-Antarctic and the Thermal Dome in the Eastern Pacific.“While the Race to Ratification will soon come to an end, the hard work to fully implement the treaty is just about to begin. Protecting and sustainably managing the High Seas – 50% of the planet – cannot come soon enough. The inclusion of Indigenous and local knowledge systems in the BBNJ Treaty sets new ocean governance foundations for how and for whom this treaty is implemented,” said Ernesto Fernández Monge, International Oceans Director at Oceans North.

Small investments with great impacts. Territorial gender-just climate solutions
Since 2016, the Global Alliance for Green and Gender Action (GAGGA), together with other actors, has promoted a series of initiatives to strengthen the inclusion of a gender perspective in climate finance, particularly within the projects and financial flows of the Green Climate Fund (GCF).The GCF is the first international climate finance fund to incorporate a gender perspective as a central pillar of its operations, becoming a key framework for advancing equity in the access, use, and allocation of climate resources globally.However, international climate finance that reaches countries is often disconnected from the actual needs of the local communities it is meant to benefit— especially women. This poses a critical issue that demands urgent attention— communities have the right to participate in decisions that directly affect them. At the same time, it misses the opportunity to incorporate local knowledge into solutions— knowledge that could make them more relevant and effective in addressing the climate crisis. In its special report on climate change and land, the Intergovernmental on Climate Change (IPCC, 2022) highlights that incorporating women’s knowledge of land management helps mitigate degradation and s the adoption of integrated adaptation and mitigation measures.Gender-responsive climate finance goes beyond allocating resources to women and promoting gender equality—it requires rethinking how financial and climate solutions are designed and implemented. This means acknowledging the diversity of women, removing barriers to resource access, defunding so-called ‘false solutions’, and ing initiatives that tackle the structural causes of climate change.In Latin America and the Caribbean, many local climate solutions remain unknown to decision-makers. As a result, they struggle to receive , be replicated, or serve as inspiration for other initiatives benefiting the same communities. This publication presents five case studies of successful, locally developed climate solutions with a focus on gender and climate justice. The goal is to strengthen collaboration between those responsible for providing and implementing GCF resources and civil society organizations.The case studies show the efficiency that can be achieved when resources are channeled directly to civil society organizations and communities. All the projects were carried out with budgets under USD 50,000 and made significant contributions to transforming the structural conditions that heighten the vulnerability of territories, women, and other marginalized groups in the face of the climate crisis.

The natural wonders we could protect with the High Seas Treaty
For decades, the ocean has protected us from the impacts of climate change, absorbing 90 percent of the excess heat produced by global warming. It’s given us food and the genetic resources we use to produce life-saving drugs. As if that weren’t enough, it’s enabled millions of families to thrive in an economy based on its bounty.Despite its importance, the ocean remains unprotected in large part; no country governs the high seas, international waters that comprise 64 percent of the ocean’s total surface area. Management measures have given rise to a patchwork of uncoordinated protections.To fill this gap, in June 2023, UN member countries formally adopted an agreement to protect biodiversity in the high seas, which requires ratification by at least 60 countries to enter into force.The High Seas Treaty - short name for the Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ Agreement) - proposes, among other aspects, the creation and adequate management of marine protected areas (MPAs) in the high seas, regions that would allow for the conservation and rescue of the rich biodiversity found in the ocean. Protection at a high costIn addition to absorbing a large part of the planet’s excess heat, the ocean absorbs nearly 30 percent of all greenhouse gases, which are responsible for climate change.But this protective role comes with serious consequences. By interacting with and absorbing pollutants such as carbon dioxide, the ocean suffers from acidification - a phenomenon that reduces the levels of calcium, an element necessary for the shells and external skeletons of several species of marine fauna - and loss of oxygen, essential for life under the sea.These impacts consequently affect the food supply and employment in the fishing and tourism industries.Faced with the impacts of the climate crisis on marine ecosystems, governments must do much more to protect the ocean, starting with ratifying the High Seas Treaty, which establishes a clear legal framework and process for maintaining its health and resilience. Protected natural wondersAs the ratification of the High Seas Treaty progresses, there is growing interest from governments and civil society to lay the groundwork for greater protection of the high seas.As part of this push, areas of high ecological value have been identified that could form the first wave of protection once the treaty goes into effect. High Seas Alliance - a coalition of organizations of which AIDA is a member - has highlighted 8 priority sites that could be part of this first generation of MPAs, which it has called the Hidden Natural Wonders of the World:Salas y Gómez and Nazca Ridges: Deep in the waters of the southeastern Pacific, these two unique chains of submarine slopes and peaks are separated from South America by the waters of the Humboldt Current and the enormous chasm of the Atacama Trench. They are critical habitats and migratory corridors for at least 82 threatened or endangered species, along with many others of ecological and economic importance.The Termal Dome: Each year in the eastern tropical Pacific, strong seasonal winds push warm waters from the coast offshore, where they meet cooler waters carried by ocean currents. This interaction causes a unique upwelling system that brings cold, nutrient-rich waters to the sea surface, benefiting many species.Emperor Seamounts: Located in the North Pacific, this chain of more than 80 seamounts extends for 2,000 kilometers on the seafloor between the northwesternmost point of the Hawaiian Islands and the Kuril-Kamchatka Trench (Pacific Northwest). Its nutrient-rich waters feed a great diversity of species. And in the mountains, a range of corals and sponges shelter countless species of fish and invertebrates.Walvis Ridge: It is a range of seamounts that extends for about 3,000 kilometers off the coast of southwestern Namibia to the mid-Atlantic ridge (submarine ridge that runs along the Atlantic Ocean). It is composed of several seafloor types and includes many features of the deep ocean floor, along with its abyssal plains, seamounts and guyots (seamounts).Sargasso Sea: It is the only sea in the world without land borders. It is geographically defined by four Atlantic Ocean currents in an area of about 1,100 kilometers wide and 3,200 kilometers long. It is called the “golden rainforest of the high seas” because of the sargassum algae that float on its surface and provide habitat for a myriad of species, while absorbing and storing carbon and producing oxygen.South Tasman Sea: Located between Australia and New Zealand, it is a diverse and dynamic area that s abundant marine life. It is also an important breeding area and migratory corridor for a large number of species, including endangered species such as the Antipodean albatross, which often transit its waters.The Lost City: It is a complex of 30 hydrothermal vent chimneys located on the upper slopes of the Atlantis seamount massif in the North Atlantic Ocean. The complex of vents rises 4,300 meters from the seafloor, with peaks at a depth of 750 meters. The Lost City chimneys are believed to be more than 120,000 years old.Saya de Malha: Located in the heart of the Indian Ocean, midway between the Seychelles and Mauritius, this unique seascape is home to the world’s largest seagrass community. It is a rare example of seagrass meadows on the high seas and the largest submerged ocean bank in the world, covering more than 40,000 square kilometers.Preserving these natural wonders through marine protected areas requires the entry into force of the High Seas Treaty.It is time to take care of the ocean as it takes care of us.
