LAND IMPRINTING FOR LOW-COST REVEGETATION OF DEGRADED LAND

Vast areas of land have been degraded by human activities in semiarid and arid regions of the world and now need to be revegetated to control erosion and restore biomass production. Hillslopes in more humid regions have suffered similar degradation and need a dense vegetative cover to control accelerated runoff, erosion and downslope flash flooding and sedimentation. However, low-cost methods that work efficiently have not been available to accomplish revegetation under such adverse conditions on a broad scale.
