Fertilizer had been part of the technological trinity (improved seed, irrigation, and fertilizer) responsible for bringing about the Green Revolution of Latin America and Asia. Its adequate and efficient use should, therefore, be a main ingredient in achieving food security in Sub-Saharan Africa (SSA). At present, average fertilizer use intensity in SSA is the lowest compared to anywhere in the world and the region needs to take affirmative action to improve the situation.

Rainfall shortage is a major production risk for smallholder farmers. Due to rainfall shortage, smallholders limit the use of modern inputs such as fertilizer and improved seeds. This study investigates if water harvesting technologies (WHTs) induce fertilizer use and whether there is joint adoption of fertilizer and water harvesting technologies. Using panel data collected from Ethiopian farmers in two regions in 2005 and 2010, a random effects probit model and a bivariate probit model are estimated to investigate these two issues.
