Abstract :

In future, soil erosion will be a great challenge for biosphere. If the soils today are notprotected carefully hunger crises all over the world will be widespread. The present article endeavorsto survey soil erosion process and approaches to prevent it. Furthermore the article tries to review therelation between soil character and soil production capability shedding light on the effect of erosion onsoil characters. There will also be a review of presented models by Pimentel and et al (1995). Finallythe results of economic valuation of erosion damages in different parts of the world will be analysed.Cost – Benefit analysis will be done with regard to soil erosion. The article will be concluded byplacing emphasis on the importance of economic valuation of erosion and the necessity of soilprotection
