Dallol Maouri (Niger)

Weather…

The Dallol Maouri is a fossil river valley in southwestern Niger, stretching for hundreds of kilometers and representing one of the country's most fertile regions today. Although the original river dried up millennia ago, the valley collects significant amounts of water during the rainy season and possesses an exceptionally high water table. This enables intensive agriculture, particularly the cultivation of rice, onions, and various vegetables that are essential for supplying the capital, Niamey. The region is densely populated, primarily home to the Maouri people, a subgroup of the Hausa ethnic group. The geomorphology of these 'dallols' is characteristic of western Niger and functions as a vital ecological corridor for flora and fauna. Due to its international importance for bird conservation, the area has been designated as a Ramsar wetland. It combines abundant natural resources with a centuries-old agrarian culture.
