| Zusammenfassung |
| Sub-Saharan Africa (SSA) has been faced with frequent drought events in the past. Future
climate change scenarios have suggested increasing drought frequency and severity. The
devastating impacts of drought on rainfed farming and food production pose many challenges
in SSA countries both today and in the future. Therefore, a comprehensive investigation of
droughts and assessment of their impacts on crop yield and production are critically
important to support SSA to formulate effective adaptive measures to improve food
security. The current study assesses the historical meteorological and agricultural
droughts and quantifies their impacts on two major crop yields namely maize and
cassava in SSA. The GIS-based crop model (GEPIC) is used for the simulation of the
historical yields. Drought severities are categorized into levels of mild, moderate and
severe. The impacts of each category on maize and cassava yields are examined
and drought hotspots are highlighted. The knowledge learnt from the historical
data helps enhance the projection of the impacts of future weather conditions on
crop yield in the region and facilitate the societal preparedness to drought impact. |
