A resilient agricultural system is able to continue to function and provide essential ecosystem services, such as food provisioning, following an external shock. If drought occurs, a more resilient system should offer higher productivity and food security. The review asks whether CA improves productivity and food security when rainfall is poor, and what aspects of CA contribute most to these benefits. The review will guide the design of a field study on the impacts of CA after the 2015/16 El Nino drought in southern Africa. Conservation agriculture combines three basic sets of technologies or practices: i) minimum or reduced tillage, ii) maintenance of soil surface cover using crop residues, and iii) crop diversification using rotations. CA has been identified as a climate smart agricultural practice because it improves crop productivity, improves resilience of cropping systems to climate change, and mitigates greenhouse gases. In Southern Africa two forms of CA have recently been promoted: a manual version based on digging planting basins, and a mechanised practice based on the use of soil rippers and direct seeders or jab planters. Due, in part, to inaccessibility of CA equipment, most smallholder farmers in the region are practising manual CA techniques...
