This article deals with the technical and hydraulic studies for the development of a 5HA site for irrigation purposes in the FADAMA2 valley, in commune 1 of Tahoua. The objective of this study is to: propose a sustainable development plan for an irrigated area of 5 ha in the said valley in order to improve agricultural productivity and the living conditions of farmers through irrigated production. The methodology adopted consisted of carrying out socio-economic, topographical, hydraulic, hydrological, pedological and environmental studies at this site. The results of the study reveal: (i) the support of the population of Founkoye for this project, (ii) the topographical surveys allowed the determination of the surface area (5 ha), (iii) the determination of the different hydrological parameters, (iv) pedological studies which made it possible to determine the suitability of the soil for irrigated crops. These results contribute to the design and sizing of the development as well as the estimated cost of the work. The summary environmental and social impact study highlighted positive and negative impacts for which mitigation measures are proposed in the environmental and social management plan. The financial analysis is carried out to determine the financial feasibility of this development project.
