Project title

Climate change impacts on water resources and adaptation through policy responses in the Logone River catchment, Central Africa Region

Project overview

Climate change is predicted to result in major hydrological changes, with increased frequency of extreme events in the form of droughts, floods and storms. The main objective of the proposed research will be to assess the impact of climate change on surface water availability in an area that is expected to be substantially affected and develop adaptation options.

The research wil involve an interdisciplinary approach where I am working at the Science-Policy Interface. The first part of my work is investigating the impacts of climate change on water resources in the Logone catchment, Lake Chad Basin. The second part will be to work with policy makers to know the kind of information that they need from climate science community and how the information should be packaged to enable them develop appropriate climate change adaptation policies. In the first part of my research I will be running simulations for the study area using both catchment hydrological model(s) and climate models (Ensemble models of the CMIP3/5) for different time horizons and under different climate scenarios. Meanwhile the second phase will involve fieldwork where I will go down to the field specifically to Cameroon to conduct interviews with stakeholders involve in the development and implementation of climate change adaptation policies within all sectors of the economy. By the end of my PhD research, I will develop a methodology to merge the science and policy components of my research together to form one entity.
