The Adaptation Fund Climate Innovation Accelerator (AFCIA) is a programme of the Adaptation Fund, implemented by the World Food Programme (WFP) Innovation Accelerator in Munich. It identifies, supports and scales locally rooted climate-adaptation solutions that protect food systems and livelihoods in communities hit by droughts, floods, storms and rising temperatures. AFCIA runs four regional cohorts from 2024 to 2029. Each year focuses on a different region. The first cohort (2024) supported ventures implementing in Egypt, Jordan and Lebanon. The Asia-Pacific sprint (2026) includes ventures in Nepal, Pakistan and the Philippines. The third cohort targets Latin America and the Caribbean, with a live call for solutions tailored to climate-adaptation challenges in the Dominican Republic, El Salvador and Peru. The programme contributes to SDG 2 (Zero Hunger) and SDG 13 (Climate Action). It seeks both low- and high-tech innovations from established legal entities (for-profit, nonprofit, social business, NGO or INGO) that already have a presence in the country of implementation and are at least seed stage. Selected teams join a bootcamp, then can enter a nine-month Sprint with WFP support and equity-free funding. Applications for the LAC cohort close 13 September 2026, 23:59 UTC; only English submissions are accepted.
