There is a growing need to investigate different crop production systems that prevent soil degradation while increasing productivity. Conservation agriculture (CA) offers a promising solution. Conservation agriculture is a climate resilient technology and management system that has demonstrable potential to secure sustained productivity and livelihood improvements for millions of climate-dependent farmers working in semi-arid areas around the world. Success stories are recorded for some countries in Asia, and in Australia and Brazil. However, for sub-Saharan Africa adoption of the technology has lagged behind these other countries, and concerns have been raised as to the suitability of the technology within the smallholder farming context.

The already vulnerable Sahel area is highly exposed to climate change impacts due to the strong dependence of its population on rainfed agriculture and livestock. Rainfall variability, land degradation and desertification are some of the key factors that are heavily impacting on local livelihoods. Droughts with varying degrees
of severity occur in two out of every five years, making harvests of the major food and cash crops highly uncertain. The recurrent droughts of the 1970s and 1980s caused huge losses of agricultural production and livestock, the loss of human lives to hunger and malnutrition, and the massive displacement of people and
shattered economies. Most climate models predict that the Sahel region will become even drier during this century.
