Small in size, generous in community-led solidarity
Every contribution — a story, an hour, a partnership — strengthens the network across Southeast Asia.
Forests, oceans, climate adaptation, and conservation across the region.
Southeast Asia hosts four of the world's biodiversity hotspots and the planet's third-largest tropical rainforest. Environmental solidarity here spans Heart of Borneo reforestation that crosses the Brunei-Malaysia-Indonesia border, mangrove and coral restoration in the Coral Triangle, and climate adaptation in the Mekong Delta and typhoon-exposed Philippine coastlines. ASEAN environmental work is necessarily transnational: orang-utans ignore borders, river systems ignore capitals, and typhoon tracks ignore politics. Solidarity efforts support Indigenous-led conservation, fund marine protected areas, finance renewable transitions, and amplify frontline community voices. Bangkok's volunteer river-cleanup drives, Hanoi's electric bus corridors, and Brunei's car-free zones show municipal action adds up.
