investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. in investigation of pedological criterion onland degradation in quaternary rock units, first, a part of the rude-shoor watershed area was selected. after distinguishing target area, maps of slope class...

     Desertification was recognized in Iran several decades ago. This phenomenon has gradually affected half the provinces in the country, where droughts exacerbate problems in these drylands. In response, the government has been active in providing considerable funds and human resources to halt desertification through investing in national research and executive projects over the last fifty ye...

Investigation of desertification trend requires an understanding of phenomena that create changes singly or action and reaction together in an area that these changes were led to the desertification and land degradation. In the investigation of pedological criterion affecting on land degradation in Alluvial Fans, first, the map of units was created by overlaying and crossing maps of slope class...

Land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. The rate of thisphenomenon is high in developing countries such as Iran. This research investigated desertification and mapping ofdesertification in Abuzaydabad, near Kashan, Iran, with an emphasis on land criteria using an IMDPA model.Different studies have assessed land degradation or desertificat...

Desertification in arid, semi-arid and dry sub-humid regions is a global environmental problem. Considering theincreasing importance of desertification and its complexity, the necessity of giving attention to desertification criteria andindices is essential. Models and methods such as MEDALUS, UNEP-FAO, and others have been proposed on local andnational scales. In this research, IMDPA was selec...

Knowledge of behavior climatic indexes can be help to planning future programs Bahabad study area in the eastern part of the province of Yazd with a hot and dry climate, high potential evapotranspiration and low rainfall has a high potential for desertification. The aim of this research is evaluation of classification intensity by IMDPA model with emphasis to climate criteria. The indices inclu...
