Description

In many tropical countries, the landscape appears lush and green - like a rich and fertile farmland. But this vegetation often covers a fragile soil and if the land is carelessly farmed, heavy rains can cause severe erosion leaving the soil dry and lifeless.
Nevertheless, erosion can be controlled through a variety of soil conservation measures, and it is now possible to access the relative benefits of these by using accurate filed measurement techniques. This video explains some such techniques, that take the 'drainage basin approach' to measure erosion.
