Coupling groundwater availability and soil ability to delineate appropriate land for agricultural uses in the dry tropical ecosystem of Tchéboa (North Cameroon)

Sustainable agriculture in developing countries must be developed on suitable soil and where quality water resources are available. Matching these two prerequisites allows the mapping of the best-suited location for agriculture. Therefore, the present study aims to combine soil ability and water resource availability to delimit the most suitable areas for agricultural practices in the Douka Longo watershed in North Cameroon. During the period from November 2019 to August 2021, several field tests were used to estimate the water resources availability and the soil potential including the infiltration test, the piezometric survey, the recharge study, and the groundwater and soil analysis. The Analytical Hierarchy Process (AHP) approaches and the ArcGIS tools were used to produce the most suitable areas for agricultural practices with the following parameters (groundwater static level, recharge, pH, Na
