This paper is based on a review of experiences with a wide range of micro-agricultural water management technologies in sub-Saharan Africa with a special emphasis on southern Africa. The major finding of the study is that these technologies have the potential to make major contributions to improving food security, reducing rural poverty and promoting broad-based agricultural growth. However, there are serious policy impediments to successfully scaling out the use of these technologies at both national and regional levels. The paper makes seven specific policy recommendations whose implementation would enable promotion of wider uptake.

The alternative to increasing the world's irrigated area by an estimated 30% to secure food security for all, seems to be limited irrigation expansion and consequently higher food prices and probably food shortages. This paper explores other options for ensuring food security. It discusses meaningful similarities between innovative approaches for land and water management in rainfed and irrigated agriculture. The focus is on innovative approaches to increase yields in sub-Saharan Africa and South Asia. Innovative technologies, such as improved tillage practices and water harvesting are important. But at least as important are the processes by which new agricultural practices are developed, improved and extended. In the end it comes down to human inventiveness.

The agricultural system in Sub-Saharan Africa (SSA) is dominated by traditional farming practices with poor soil and water management, which contributes to soil degradation and low crop productivity. This study integrated field experiments and a field-scale biophysical model (Agricultural Policy Environmental Extender, APEX) to investigate the impacts of conservation agriculture (CA) with a drip irrigation system on the hydrology and water management as compared to the conventional tillage (CT) practice. Field data were collected from four study sites; Dangishita and Robit (Ethiopia), Yemu (Ghana), and Mkindo (Tanzania) to validate APEX for hydrology and crop yield simulation. Each study site consisted of 100 m2 plots divided equally between CA and CT practices and both had a drip irrigation setup. Cropping pattern, management practices, and irrigation scheduling were monitored for each experimental plot. Significant water savings (α = 0.05) were observed under CA practice; evapotranspiration and runoff were reduced by up to 49% and 62%, respectively, whereas percolation increased up to three-fold. Consequently, irrigation water need was reduced in CA plots by about 14–35% for various crops. CA coupled with drip irrigation was found to be an efficient water saving technology and has substantial potential to sustain and intensify crop production in the region.
