In Myanmar’s Kawthoolei region, the Karen Environmental and Social Action Network (KESAN) is using participatory mapping to secure Indigenous Karen land rights and protect one of the planet’s most critical biodiversity hotspots. Working alongside the Karen National Union and local communities, KESAN combines Indigenous knowledge with GIS technology to document community forests, farmlands, and conservation areas. With digital tools and training from Cadasta, KESAN has mapped more than 3.5 million hectares and facilitated the issuance of over 107,000 land titles. These efforts enable Karen communities to safeguard their territories against encroachment, preserve biodiversity, and build intergenerational resilience.
