EVALUATING THE POTENTIAL FOR LOW ENERGY EMITTERS TO FACILITATE SOLAR-POWERED DRIP IRRIGATION IN SUB-SAHARAN AFRICA

Abstract

AbstractIntroducing irrigation to smallholder farms in Sub-Saharan Africa (SSA) can increase food security, improve nutrition, and reduce poverty. To explore the possibility of using drip irrigation on smallholder farms in SSA, we introduce a feasibility study that views the design space from both a user-centered lens, explaining how drip might be successful in the future, and from an engineering lens. With a first-order model, we compare estimated capital costs of drip and sprinkler systems for various farm profiles and show that drip has the potential to be a viable technology for many farms in SSA.
