An Analysis of the Performance of National Comprehensive Plans Coping Desertification in Iran Using the Morris Model

 Desertification means the destruction of land in arid, semi-arid and semi-humid regions, which are caused by various factors such as climate change and human activities. In this research, the performance of comprehensive desertification plans Including forests management, seedling, runoff management, care and irrigation, conservation, and planting of seedlings in 21 provinces of the country were analyzed using Morris model. The Morris model is the newest formal model for grading areas in terms of development (physical and human) on a global scale and is applicable for planning with different and varied scales. The results showed that the provinces of Khorasan Razavi, Isfahan, South Khorasan, Kerman, Sistan and Baluchestan, Semnan and Khouzestan with the development coefficient (DI) respectively 41.5, 40.07, 38.60, 37.28, 36.72, 32.90 and 30.42 has good condition and acceptable performance, Markazi provinces and Yazd, with the development index respectively 28.36 and 23.48 were in the middle condition, Tehran provinces, Hormozgan, Bushehr, Fars, North Khorasan, Ilam, Qom, Qazvin, West Azarbaijan, Alborz, Golestan and Hamedan with the development coefficient (DI) with the development index (DI) respectively 12.61, 10.79, 9.88, 8.96, 8.71, 5.23, 4.24, 2.50, 0.92 and 0.68 has poorly performance in studied projects. At the end, the results of the study were prepared in the form of a table and the development coefficient map of the evaluated provinces in this paper was prepared using the performance of each province from the above-mentioned plans to deal with the desertification phenomenon in the Arc GIS environment.The results of this study can be used in decision making on the performance of provinces in the country against desertification phenomena. By utilizing more comprehensive desertification plans such as seedlings, planting forests and conservation and protection, desertification can be reduced in the country.
