The Dallol Bosso is a 350 kilometer long wadi in the west of Niger . It runs from the border with Mali in the north to the border with Benin in the south, where it flows into the Niger River.

course

The wadi has its origin in the branched Azawagh river system in the Gao region of Mali. From the state border with Niger, it bears the name Dallol Bosso. Dallol is a word from the Fulfulde language and means "valley". There are several Dallols in Niger, including the Dallol Foga and Dallol Maouri further east .

The Dallol Bosso initially runs in the Filingué department in Niger through the municipalities of Abala , Filingué , Kourfeye Center , Imanan , Tondikandia and Tagazar , where it includes a side valley coming from Banibangou . After Tagazar, the wadi reaches the Boboye department . The name Boboye comes from the Zarma language , also means "valley" and is another name for the Dallol Bosso. After the municipalities of Koygolo , Kiota , Harikanassou and N'Gonga , the Dallol Bosso Birni reaches N'Gaouré , the capital of the Boboye department. It then runs through the municipalities of Fabidji , Guilladjé and Falmey , where it flows into the Niger River near the village of Boumba opposite the state border with Benin.

On its way the Dallol Bosso crosses two large landscapes: the Sahel zone and the large Sudan landscape .

Characteristics and use

The hydromorphic soils in the valley floor are rich in clay and organic matter. The water table is high. There are good conditions here for irrigation field management . At the foot of the plateaus on both sides of the Dallol there are silt and clay soils that are exposed to erosion by wind and water. Grain is grown on the plateaus themselves.

In Dallol Bosso, the population density is high compared to the surrounding area, reaching more than 100 inhabitants per square kilometer. Land use conflicts often arise. The valley is a traditional settlement area of ​​the Fulbe , which they share with other ethnic groups such as the Tuareg and Zarma .

The Dallol Bosso has been a Ramsar area since 2004 . This extends over an area of ​​376,162 hectares and is therefore the second largest of the twelve Ramsar areas of Niger after the Gueltas and oases of the Aïr .
