Abstract Most socio-economic activities in Africa depend on the continent’s river basins, but effectively managing drought risks over basins response to climate change remains a big challenge. While studies have shown that stratospheric aerosol injection (SAI) intervention could mitigate temperature-related impacts Africa, there is dearth of information how SAI influence characteristics and risk managements basins. The present study thus examines potential droughts management major Africa....
Estimates of global horizontal irradiance (GHI) from reanalysis and satellite-based data are the most important information for design monitoring PV systems in Africa, but their quality is unknown due to lack situ measurements.
