Impacts of solar radiation management on the West African climate

Project summary

The projected impacts of climate change in Benin, and more generally in West Africa, include an increase in temperatures, more severe floods, sea level rise, acceleration of coastal erosion, modification of monsoon precipitation and disruption of regional hydrology. These effects can have dramatic socio-economic consequences due to their impact on agriculture, water resources and human health. This project, hosted at the ICPMA-UNESCO Chair, will investigate how SRM may affect the impacts of climate change on the West African precipitation regime and river discharges.

Eliezer Iboukoun Biao obtained his PhD in Climate Change and Water Resources from the University of Abomey-Calavi (Benin) in 2015. A Member of the Laboratory of Applied Hydrology of the National Institute of Water at the University of Abomey-Calavi, his researches focus mainly on hydrological modelling, impacts of climate variability and climate change on water resources, uncertainties analysis and stochastic modelling. He is the author and co-author of several published papers on hydrological modelling in Benin. His experience in carrying out research began ten years ago as an undergraduate research assistant at the French Research Institute for Development in Benin. His major research experience, though, has come through the West African Climate Science Service Center on Climate Change and Adapted Land Use (WASCAL) project funded by the German Federal Ministry of Education and Research (BMBF). WASCAL is a large-scale research-focused program designed to help tackle the challenge of climate change and thereby enhance the resilience of humans and environmental systems to climate change and increased variability. It does so by strengthening the research infrastructure and capacity in West Africa related to climate change and by pooling the expertise of ten West African countries and Germany.
