Despite this importance, most smallholder farmers depend on rain-fed agriculture, leaving them highly exposed to erratic rainfall and recurring droughts. SunCulture has grown to serve more than 60,000 customers and now holds a dominant share of the solar irrigation market in sub-Saharan Africa. The study compared adopters of solar irrigation with non-adopters and found substantial increases in irrigation use, with a higher share of farmland coming under irrigation. Overall, the findings suggest that solar-powered irrigation can deliver meaningful gains in resilience, nutrition, and production for smallholder farmers in Kenya, while also supporting climate adaptation. Aligning these efforts with supportive national policies that empower smallholders to invest in their own technologies can help position small-scale solar irrigation as a resilience-first investment for sustainable agricultural growth.
