Water resource for exploitation by human in earth is very limited. The existing limited resources are degrading mostly as results of unsystematic exploitation and abuse. Lands have been subjecting to degradation affected by population growth, extended anthropogenic activities, inappropriate land uses, deteriorating operations and exploitation on water, soil and vegetation resources in turn causes to vegetation destruction, erosion, flooding, dust storms, low biodiversity and fertilized soils, less yield, unemployment and negative socio-economical outcomes. Whereby, to withstand against this situation entails for a comprehensive landscape use plan (water and earth) in which land uses are selected in a specified framework in a reasonable manner in proportion to potential of environment. In a global scale, agriculture as a land use accounting for highest area than others uses, causing large environmental impacts so that evaluation of farm lands might be essential.
