This study, conducted in the commune of Sokorbé (Western Niger), aimed to characterize half-moons (multifunctional and conventional) and to assess the applicability of technical standards according to soil types. To this end, three experimental sites were installed on three distinct landscape units: the high plateau, the low plateau, and the glacis, where nine half-moon models were studied. Data were collected primarily based on measurements during and after construction of the structures. The results showed that the single-trench, multi-trench, and conventional models are more suitable for agricultural production due to the large number of zaïs. In terms of water storage capacity, the conventional and single-trench models proved more efficient, with 1.25 m3 and 1.16 m3 per structure, respectively. Regarding compliance with technical construction standards, structures built on the glacis are closer to theoretical standards than those built on the plateaus. An assessment of construction time shows that the time taken to complete structures on the glacis is shorter than that on the plateaus. 75% of structures per unit area are completed in less than 60 minutes on the glacis, compared to 50% on the plateau soils. Structures requiring maintenance have an average lifespan of four years, twice that of structures that have not received maintenance. Therefore, the construction context and the objectives should guide the choice of half-moon structures in the Sahel.
