Niger at a Glance
Niger spans the Sahara and Sahel, with desert plains and the Aïr uplands in the north grading toward the Niger River and more seasonal landscapes in the southwest.
Physical geography
terrain · drainage · setting
Niger is dominated by Saharan plains and desert basins across the north and center, interrupted by the Aïr massif, while lower Sahelian plains extend across the south. The relief focus used here is Saharan plains, central massifs and Sahelian south, presented as a regional physical reference.

Climate pattern
The climate grades from hyper-arid Sahara in the north to semi-arid Sahel in the south, with rainfall concentrated in a short summer season and increasing southward.
Water and landform context
The Niger River crosses the far southwest and is the principal perennial river, while most northern and central channels are seasonal or ephemeral.

What Niger's geographic profile is telling you
Aridity is the main control on Niger’s geography: permanent surface water is concentrated around the Niger River, while most interior drainage responds only episodically to rainfall.
