Learning from PRIMA: Indonesian Coastal Women’s WASH Advocacy as a Foundation for Climate Adaptation examines how climate change is intensifying water, sanitation and hygiene (WASH) challenges for coastal communities in Indonesia, with women bearing a disproportionate share of the impacts. Drawing on the experiences of women leaders from Indonesia’s Coastal Women’s Union (KPPI), the learning note explores how climate risks, inadequate WASH services, insecure land tenure and large-scale development projects affect women’s livelihoods, health and unpaid care responsibilities. It also documents how, through the PRIMA initiative, coastal women have used participatory mapping, community-generated evidence, budget monitoring, social audits and direct engagement with government to advocate for better WASH services and influence public decisions. The paper shows how these proven, women-led advocacy approaches can provide a foundation for more transparent, participatory and community-responsive climate adaptation planning and financing.
