Water erosion in a millet farm
acute in the regions of Tahoua, Maradi, Tillabery and Zinder. The local office of the
Department of the Environment in Zinder, noted that firewood destined for Zinder
town is collected up to 200 km away.
Besides the problem of wood-energy due to the reduction of biological diversity,
the impact of the vegetal coverage degradation on communities' life touches other
important dimensions. In fact: 210 vegetal species directly contribute to human
feeding, particularly during food shortage and famine; 235 species are consumed
by the cattle; 270 are used in traditional medicines; 127 species in the handicraft
and habitat maintenance etc.
