Risk and crop production intensification options for semi-arid southern Zimbabwe

Although rainfed cropping in semi-arid areas is risky due to frequent droughts and dry spells, climate smart agriculture (CSA) and sustainable intensification (SI) technologies have a role to play in ensuring smallholder farmers in semi-arid sub-Saharan Africa (SSA) are food self-sufficient. Conservation agriculture (CA) and cereal-legume intercropping were identified as cropping systems that have potential to produce food in risky environments. The objective of this study was to determine the potential of CA and intercropping to contribute to SI and CSA by quantifying crop productivity and soil N dynamics using field and modelling approaches...
