| The desertification is a global problem. It is studied in several forums and recently, in the U.N.O. that said: ¿Desertification has a very high incidence in the environmental and food security, socioeconomic stability and world sustained development¿. Desertification is the soil quality loss. It is one of FAO¿s most important preoccupation. Hunger in the world is increasing. Multiple factors are involved. Ones are in relation with natural phenomena like water and eolian erosion. Others with human activities linked to soil use and water management. Finally with not proper activities. In the whole world this problem exists, but his effects and solutions are different. It is necessary to take into account economical, environmental, cultural and sociological criteria. The elaboration of a multicriteria model to select among different alternatives to prepare a integral plan in order to solve this problem in each area is the object of this paper. Eight criteria and six alternatives have been introduced in the model. Six subzones have been established following previous studies. In each subzone we have found the initial matrix and the weights applied to different criteria. Three Multicriteria Decision Methods have been used (Electre, Promethee and A.H.P.). The results show an high level of consistency among different multicriteria methods | |
