Here's a breakdown:
* Sahel: This semi-arid zone stretches across the southern edge of the Sahara Desert, and it's where the Niger River flows for most of its length. The Sahel is characterized by dry, hot weather with limited rainfall.
* Sudano-Sahelian Zone: This zone, lying south of the Sahel, also experiences the influence of the Niger River. It's a transitional zone between the Sahel and the Sudanian savanna.
* Sudanian savanna: The Niger River also flows through parts of the Sudanian savanna, a region known for its lush grasslands and savanna vegetation.
While the Niger River is primarily associated with the Sahel due to its length and influence on the region, its course also takes it through other climate zones.
