HyCRISTAL: Integrating Hydro-Climate Science into Policy Decisions for Climate-Resilient Infrastructure and Livelihoods in East Africa HyCRISTAL aims to quantify current uncertainties in projections of water availability in East Africa (Uganda & Rwanda) under future climate change.  Working with policy makers, inter-disciplinary research (hydrology, economics, engineering, social science, ecology and decision-making) will quantify risks for rural & urban livelihoods, quantify climate impacts and provide the necessary tools to use climate information for decision making. Research and development activity contributing to the UK’s strategy to address key development challenges.
