Mixed-methods evaluation shows improved irrigation efficiency in Ethiopian highlands, suggesting economic benefits for women farmers.
Solar-powered irrigation systems are increasingly being promoted as a sustainable solution for smallholder farmers in arid and semi-arid regions, including Ethiopia's highland ecosystems. A mixed-methods approach combining quantitative data from pump efficiency tests and qualitative interviews with farmer participants was employed. Solar pumps demonstrated an average daily lift capacity of 20% higher than conventional diesel pumps, reducing electricity costs by approximately 65% for farmers. The economic benefits of solar irrigation systems significantly outweigh the initial investment costs, particularly for women farmers who often lack access to formal credit markets. Government subsidies and public-private partnerships should be encouraged to facilitate widespread adoption of solar-powered irrigation in Ethiopian highlands. The maintenance outcome was modelled as Yᵢₜ=β₀+β₁Xᵢₜ+uᵢ+εᵢₜ, with robustness checked using heteroskedasticity-consistent errors.
