Analysis of water management in the irrigated area of Saga: Rate of satisfaction of water needs, performance indicators, constraints and solutions

This study was carried out on the Saga rice growing area near Niamey. The main objective is to analyze current water management practices and identify improvement opportunities for more efficient and equitable use of water resources. A mixed methodological approach was used, combining surveys of local stakeholders, direct observations and documentary analysis. The results showed that although local management structures exist, they encounter difficulties linked to the coordination of users and the maintenance of infrastructure. Traditional practices, although still in force, are not always adapted to modern challenges, such as climate variability and increasing population pressure. Regarding the satisfaction rate of water allocated to irrigators, we note an average water coverage of the area is estimated at 82% for dry season rice cultivation and 51% for rainy season rice cultivation. Regarding performance indicators, there are low levels of fluctuations in agricultural reinforcement rates, with coverage estimated at 73% during the dry season and coverage of irrigation water demand of 82%, directly at 97%. % during the campaign. Achievable with a coverage rate of irrigation water demand of 51% during the winter season. The agricultural efficiency (Ea) values of irrigation water for all crops are low. Based on these observations, solutions were proposed for good participatory governance, improving infrastructure and integrating innovative approaches to integrated water resources management. These proposals aim to ensure sustainable and long-term management of the irrigated area, while meeting the growing needs of users.
