Solar-powered irrigation in Rwanda to cover over 1,140ha by 2029

Rwanda is set to increase the area irrigated by solar power from the current 646 hectares to 1,146 hectares by 2029 under the Second National Strategy for Transformation (NST2), according to Rwanda Agriculture and Animal Resources Development Board (RAB).

Jerome Hitayezu, the head of the Department of Land Husbandry, Irrigation Innovation, and Technology Transfer at RAB, told The New Times that under NST2, “we aim to add 500 hectares of solar-powered irrigation by 2029. The yearly targets include 60 hectares by 2024-2025, 100 hectares each in 2025-2026 and 2026-2027, and 120 hectares each in 2027-2028 and 2028-2029.” “Currently, 646 hectares of farmland are irrigated using solar power, and we plan to significantly expand this coverage in the coming years. The expansion is part of a broader effort to promote sustainable agriculture and reduce reliance on fossil fuels,” he added.

Solar energy also has a positive impact on the environment and helps to lower [green] gas emissions.” Nationwide mobilization will also encourage farmers and private sector actors to implement solar irrigation systems independently, thereby expanding coverage beyond the areas subsidized by the government, he said. “This expansion is designed to complement the government's efforts to offer subsidies for solar-powered irrigation systems,” he added. The entire country is suitable, he said, for solar-powered irrigation, most specifically the eastern, southern and western-southern parts of the country. Farmers like Marie Murekatete from Ndego Sector in Kayonza District, who have already adopted solar irrigation are seeing remarkable improvements in their yields. Murekatete said that switching to solar irrigation transformed her farming operations. “Before using solar irrigation, I could only harvest one tonne of grass per hectare. After two seasons with solar irrigation, my yield tripled to three tonnes per hectare,” she said. “This irrigation system is environmentally friendly and eliminates the need for diesel or petroleum. I urge other farmers to consider switching, as we continue getting enough harvest even in the summer when others are no longer cultivating.” Murekatete has used solar irrigation since 2020 and, despite the high cost, found it a worthwhile investment. The system cost me Rwf64 million, and it helps me to irrigate five hectares. The only challenge is managing the labor required as I currently employ four workers to assist with irrigation. According to Hitayezu, the cost of solar-powered irrigation systems varies depending on the specific design and the area of land being irrigated. However, the benefits such as lower operating costs, reduced negative environmental impact, and increased yields, he noted, make it an attractive option for farmers.
