In areas of oasis ecosystems existence such as Niger, where about 77% of the territory is occupied by Saharan zone (MESUDD, 2019), which does receive only about 150 mm of maximum rainfall per year. Water is the central challenging component of livelihoods and development in rural areas. In Niger, in the oasis areas mainly in the Agadez and Zinder regions (Air, Damagaram & Manga), there are hundreds of small scale farmers with associated livestock practices in the oasis ecosystems. But, facing various climate events water scarcity and availability in food and energy production for communities’ livelihoods. Indeed, many of them need an intervention to help them cope with these problems. Even though, people use traditional practice (Indigenous and local knowledge) to collect rainwater, where mountain tributaries constitute a wide quantity of water in flow, which can be shown by the flooding, where thousands of m3 are lost. Indeed, this problem combined to trees absence is the main drivers of land degradation and water loss from flooding to huge loss and damage.
