On the Chinese Loess Plateau (CLP), a project named “Gully Land Consolidation” (GLC) has been implemented in rural watersheds to offset the farmland loss induced by “Grain for Green Program”. Its main goal includes reshaping creek valleys by incising foot slopes, filling stream channels and ditches, constructing drainage canals, dams and reservoirs, and creating flat farmlands.
