This Guidance Note provides UNICEF WASH staff with entry points and guidance for the design and implementation of programmes that are grounded in a comprehensive understanding of climate risks, and that set clear climate-based rationales as a central element. This guidance is intended to be used for UNICEF programming in all contexts, including protracted conflicts, fragile or humanitarian settings, as well as development contexts. It will also hopefully inspire and be useful for those developing WASH programming for other WASH actors.
