Harsh climate, characterized by low and erratic precipitation patterns, droughts, and poor soil fertility decrease cereal production in Sub-saharan Africa. Considering that soils in semi-arid west Africa are highly weathered with very low nutrient reserves, long-term sustainability of fertilizer microdosing techniques need to be studied. Research indicates that rain water harvesting (RWH) alone can increase yields of cereal crops by 30 – 50 % in semi-arid areas, due to reduced runoff and enhanced infiltration by RWH structures. Combined with micro-dosing technology, plus better access to credit, there is a high potential for farmers to address issues of poverty and food insecurity.
