Wind erosion control within Niger

ABSTRACT:

Sandy soils and strong winds create conditions for soil erosion within the Sahel region of Niger. The loss of topsoil is problematic within the area because land degradation contributes to lower agricultural productivity which in turn affects the economic viability of the society. Research conducted within the region has assessed how technological, socioeconomic, institutional, and policy factors have influenced wind erosion control efforts. Research findings indicate that population and deforestation are the primary human factors that contribute to wind erosion within the region. Technological solutions are favored by local people as the best means of stabilizing dunes. Local people also favor use of crop residues and bushes to protect soil surfaces. Characteristics of erosion control measures that facilitate adoption are low economic cost and simplicity. Land operators prefer erosion control systems that emphasize use of local skills and inputs that can be secured locally.
