Note: It is important to note that most causes of degradation are closely interdependent and thus mostly more than one cause lead to the prevailing erosion features. For example, according to Berry (2003), the cause of land degradation involves two interlocking complex systems: the natural ecosystem and the human social system. Faulty irrigation projects have resulted not only in the soil infertility, they have also decreased water table of the country’s largest lakes by 80 percent and more, exposing shores to the effects of rapid drying out and land degradation [14].
