Description :
Caused by the increase in population China needs more ground for agricultural use. The problem in the karst regions is that intense use imply soil erosion. Steep slopes, the dominant shape of numerous karst landscapes additional speed up soil erosion. Even arable land of plains, which are covered with an enormous soil-cover (up to 7 m terra rossa in the southern province Huna) are wasted by increase in gully formation.
