Proposed policies for integrated watershed management in order to combat desertification in Euphrates and Tigris basin Abstract Desertification of the arid and semi-arid lands of the world has been proceeding for more than a thousand years.
So qualitative analyses of data banks of the countries involved in this basin have been collected by FAO consultants, showed desertification in Euphrates and Tigris Basin is characterized by climate factors and human activities; water scarcity and unequal distribution of water are major climate factors.
Because of negative impacts of human activities on climate factors and also deep dependency of livelihood in this basin, there is an urgent need to plan an integrated watershed management in order to managing people, water, forests, and range lands together for combating this progressive desertification.
In Euphrates and Tigris Basin water scarcity and unequal distribution of water are major climate factors and main human activities consist of overgrazing of rangelands, deforestation, and land use changes (changing forests and rangelands into agricultural lands) (Altinbilek, 2004).
showed lack of explicit policies related to integrated management and sustainable use of lands in Arab Region caused to accelerate the rate of land degradation and desertification process.
Also they showed failures of resource management policies are aggravated by overgrazing, overexploitation of water and land resources, overcultivation of marginal lands, deforestation, and the use of inappropriate technologies due to lack of an integrated management system (Abahussain, Abdu, Al-Zubari, El-Deen, and Abdul-Raheem; 2002).
The purpose of this research is proposing appropriate policies in terms of main driving forces in order to combat desertification in Euphrates and Tigris Basin.
