The economy of Diffa Region is primarily agricultural, based upon pastoralism and farming. The major crop, grown both for subsistence and sale, is
millet, especially the drought-tolerant varieties. One third of arable land is devoted to farming: almost 105,000 hectares farmed of the 299,500 hectares of arable land. Areas of the east and south also grow
rice and
maize. Irrigation in the valleys around
Maïné-Soroa make this possible, as does the edge of
Lake Chad (3,000 km² in the far east) and the seasonal
Komadougou Yobe river valley in the south. This river valley forms around 150 km of the border with
Nigeria. Despite this, the Diffa Region is among the most unproductive agricultural areas in Niger, and all of West Africa, making it especially vulnerable to drought and famine. == See also ==
