The Goulbi N'Kaba is a seasonal river in southern Niger, flowing primarily through the Maradi region and serving as a major tributary to the Rima River in Nigeria. It carries water only during the brief rainy season from June to September, but it leaves behind extremely fertile sediments in its valley that are extensively utilized for agriculture. The Goulbi N'Kaba valley is famous for cultivating tobacco, vegetables, and various grains, making the region one of the nation's key economic hubs. Historically, the river valley served as a central migration route for nomadic herders and a preferred settlement area for sedentary farmers. Water management in this area is a significant challenge due to extremely high evaporation rates. Nevertheless, the residual water holes during the dry season act as vital lifelines for local wildlife and livestock. The region is regarded as a model for adapting to seasonal water availability in the Sahel.
