Does conservation agriculture work as advertised? Implications on labor and farm returns in sentinel sites in Malawi and Zambia
Sub-Sahara Africa (SSA) has degraded soils, epitomized by decades of loss of valuable topsoil caused by continuous cultivation, monocropping, excessive run-off, and the absence of effective conservation-based farming practices. Conservation Agriculture (CA) offers several opportunities to restore land and arrest soil degradation in smallholder farming systems of SSA. This study assessed labor productivity and farm returns associated with CA in Malawi and Zambia using household survey data collected from 500 and 616 farmers in Zambia and Malawi, respectively.
