What is soil erosion A.water erosion B.Wind erosion C.Tillage erosion 2.The current sitiation in bolivia A.loss of vegetation cause erosion B.Population pressure 3.What cause soil erosion A.Removal of the vegetation cover. B.Poor arable farming methods lead to soil damage. C.Poor pastoral farming methods lead to soil damage. D.Urbanisation, highway construction and industry tend to consume vast areas of our most fertile farmland. 4.Why it is important? A.Soil erosion leads to desertification.

Careful management of irrigation, to prevent the application of too much or too little water, should help reduce the problem of salination. C. Livestock grazing rates must be carefully managed to prevent overgrazing. D. Attempt to restrict highway construction and urbanisation to areas of lower agricultural potential. 10.Source Link
