With a reduction in capacity of bilateral and multilateral institutions and a broader political retreat from environmental protection and peacebuilding, environmental peacebuilding reached a turning point in 2025. This was the conclusion of leading experts who spoke at The Year in Review and the Year Ahead  webinar hosted by the Environmental Peacebuilding Association, as they reflected on the mounting constraints posed by this altered landscape.

Rapid Central Asia Glacial Melt Threatens Water Security (The Diplomat) 

A recent study projects that the Tian Shan mountains, the primary freshwater source for millions across Central Asia and China’s Xinjiang region, will lose approximately one-third of their glacier area before 2040. Already, the region has seen a 27% drop in glacial mass and an 18% drop in areas over the last 50 years. The Tian Shan’s smaller glaciers respond more rapidly to warming temperatures, as rising temperatures reduce the snowfall that historically replenishes glacial mass. These glacial and meteorological conditions create a compounding effect that makes the Tian Shan more vulnerable than the larger, slower-responding glaciers of the Karakoram, Pamir, and Himalaya ranges.

Illegal and Unregulated Mining Runs Rampant in Venezuela (Inside Climate News) 

Located across the Venezuelan states of Amazonas, Bolívar and Delta Amacuro, the Orinoco Mining Arc is a center of mining illegal and unregulated mining activity. Mining has exploded in this area during the Maduro regime, as operations use high-pressure pumps and toxic mercury to strip vast stretches of Amazon rainforest, and choke rivers with sediment and pollutants. Recent activities even carved open-pit mines into the summit of Yapacana National Park’s sacred tepuy mountain. The environmental impacts on populations are also devastating: up to 90 percent of women in mining areas show toxic mercury levels that are linked to neurological damage.

Deforestation and Flooding Turns Fallen Timber into Projectiles in Indonesia (The New York Times) 

When Cyclone Senyar struck in late November, its death toll numbered 800 people across Indonesia, Malaysia, and Thailand. The Indonesian island of Sumatra saw a particular sort of damage as the storm unleashed sixteen inches of rain in parts of the island, wiped out four villages, and triggered flash floods and landslides. Decades of razing and converting natural forests into palm oil plantations, pulpwood farms, and gold mines drastically increased the region’s vulnerability to floods and landslides to the point that timber was transformed into projectiles that destroyed residences and infrastructure.

As COP30 Concludes, Experts Call for Reform (Reuters) 

Interviews with experts attending COP30 highlight a growing movement for reform to the UN climate negotiations. In particular, there is alignment on a key critique of the current COP structure which calls for a full consensus of nearly 200 countries to make decisions. Since this requirement historically has allowed more ambitious efforts to be blocked during negotiations, suggestions for reform have included the following: a shift to a majority-vote model, holding COP every other year, convening smaller action-focused gatherings, and downsizing COP to exclude big business contingents.

Revisions to Indonesian Law Promote Unregulated Mining (The Diplomat)

Since gold was discovered in 2011 on Mount Botak in Indonesia, thousands of miners have flocked to the area without official permits. It is an influx which has transformed this northeastern region from an agricultural center into a hub of small-scale, unregulated mining. Uncontrolled use of mercury and cyanide has severely polluted local rivers, with mercury levels in the Waekase River reaching 0.05 mg/L—or 50 times the WHO’s safety threshold. Yet despite the government’s move to close the mine in 2015, illegal activity continues.  Ineffective law enforcement has caused ecosystem destruction, public health threats (including neurological disorders and kidney damage) and deadly conflicts between residents.

Nickel Mining Threat to New Raja Ampat UNESCO Biosphere Reserve (Mongabay) 

When Indonesia’s Raja Ampat archipelago received a UNESCO Biosphere Reserve designation on September 27, 2025, the new designation adding to the status it won as a Global Geopark in 2023. Yet this dual honor highlighting the archipelago’s exceptional biodiversity is now under threat from intense pressure from global demand for nickel for electric vehicle batteries that is challenging the reserve’s conservation goals.

Mexico’s Mercury Boom is Poisoning People and the Environment (Associated Press)

In Mexico’s Sierra Gorda mountains, soaring international gold prices also have created a mercury boom. Since 2011, mercury prices have skyrocketed from $20 per kilogram to between $240 and $350 per kilogram today. Most of Mexico’s mercury is trafficked to Colombia, Bolivia, and Peru for use in illegal Amazon gold mining operations that contaminate rivers and ecosystems. Yet the country’s adoption of a 2017 UN convention banning mercury mining and exports also allows artisanal mines to operate until 2032.
