Rehabilitating degraded arid lands: options and decisions

, : Rehabilitating degraded arid lands: options and decisions. Problems of Desert Development ( 3): 19-22

Land degradation affects three-quarters of the world's grazing land, half of the rainfall cropland, and a quarter of the irrigated land. Reclamation is cost-effective for almost all irrigated land, on two-thirds of the rainfed cropland, but only half the grazing land. Since it is often socially or politically unacceptable to reduce stocking rates or cultivate unsuitable land, ways should be sought to reduce land pressures voluntarily.
