Desertification phenomenon is not devoted to an especial climate, although its role in arid and semi-arid areas is clearer than other regions. In this research, four criterions of the wind erosion, soil, vegetation cover and climate have been considered for evaluating desertification potential and mapping of desertification intensity using to IMDPA model in ZAHAK Sistan region. Considering to e...
in many countries, studies to determine the severity of desertification and providing land plans to implement desertification. one of the models is modified medalus or iranian model (imdpa), has been used in present research in order to investigate desertification situation in the tashk region of fars province. in this research, the modified imdpa model used with emphasis on the water, soil and...
Desertification is more related to social and anthropogenic issues than natural causes and it becomes moreimportant over the time. Human effects on desertification could be classified as direct and indirect factors. This studyhas focused on the effect of management factor, as a dominant case, on desertification of Kashan region based onIMDPA (IMDPA: Iranian Model of Desertification for Potentia...
Desertification could be traced back to one or many factors. Thus, to cope with such a phenomenon, there exists a need for a profound understanding of the processes and the causes. The study area of the current paper is the extent of Shahrekord’s Marghzar as an important case amongst the important ones of the province. In order to evaluate the roots of desertification in the area, the Iranian m...
this study used quantifying factors affecting desertification based on the iranian model of desertification potentialassessment (imdpa) to assess the current status of desertification in bordekhun region, iran. bordekhun region has anarea of 214.11 km2 and is located near the city of daiyer in boushehr province. first, a working unit map of the regionwas selected as the basic map for evaluation...
Desertification is recognized as a serious environmental threat in Iran because of its climatic-geomorphologicconditions. Desertification and land degradation in arid, semi-arid, and dry sub-humid regions, is a globalenvironmental problem. Accurate assessment of the status and trend of desertification is instrumental in developingglobal strategies to prevent and reverse this problem. The goal o...

Bordekhun region has anarea of 214.11 km2 and is located near the city of Daiyer in Boushehr province. First, a working unit map of the regionwas selected as the basic map for evaluation...
Now days desertification of lands in phenomelal that threaded different region of world specially arid, semi arid and semi-arid humid. In this research whit using of two Irainian new methods: IMDPA that is based on geometric sum and MICD that is based on arithmetic sum. Desertification capacity of Lar city area during recent half century (from 1995 to 2005) has considered with emphasis on facto...
