The study looked at how well public irrigation schemes in Kenya are performing. Researchers used a method called benchmarking and principal component analysis to measure the performance of these irrigation schemes. They found that the agricultural productivity, water supply, and financial performance of the schemes were quite low. For example, the agricultural productivity ranged from 36% to 51% in Ahero, 23% to 42% in West Kano, and 26% to 50% in Bunyala. Water supply performance varied from 24% to 58% in Ahero, 3% to 49% in West Kano, and 19% to 43% in Bunyala. Financial performance also showed low numbers. Overall, the performance of the irrigation schemes was found to be very poor, and improvements are needed.
