In Mustang, one of Nepal’s most climate-vulnerable districts, Indigenous women in Jomsom are leading a quiet but impactful transformation by reviving a traditional water mill. The initiative addresses multiple challenges, including reducing women’s daily workload, conserving Indigenous knowledge, and strengthening community-based climate adaptation. At the same time, traditional knowledge and technologies have been declining, with women’s needs and expertise often absent from local development processes. The restoration of a traditional water mill emerged as the top priority, aiming to conserve Indigenous skills, reduce the physical burden of long-distance grain grinding, and promote climate adaptation through renewable energy and water conservation. Today, the project reinforces the transmission of traditional knowledge to younger generations, highlighting the relevance of Indigenous technologies for climate adaptation, workload reduction, and cultural continuity.
