one of the characters in iranian model of desertification potential assessment (imdpa) is soil. since soil is very important in the degradation of land, so some indices were determined for this character in order to evaluate desertification potential of arid, semi-arid and dry sub humid areas of iran. the indices included soil texture, deep gravel percentage, soil depth, and ec. to calibrate th...

One of the characteristics in Iranian Model of Desertification Potential Assessment (IMDPA) is vegetation. Sincevegetation is very important factor in the degradation of land, so some indices were determined for this item in order toevaluate desertification potential of arid, semi arid and arid sub humid areas of Iran. The indices included vegetationcondition, exploit and revegetation. To calib...

More than one-third of the earth is characterized by arid and semi-arid climate and desertification phenomenon in these areas has been intensified in recent decades. This study aims to investigate the trend of desertification using vegetation indices and Iranian Model of Desertification Potential Assessment (IMDPA) in Abarkooh Plain, Yazd province, Iran. The satellite images (Landsat images in ...

desertification is specific phenomenon of arid, semi-arid, dry sub humid regions. this phenomenon has a high rate in developing countries such as iran. the main objective of this research was calibration of imdpa model in abuzeidabad (kashan) region with emphasis on land criteria. imdpa model, introduced by iranian researchers to assess desertification intensity in iran. before application, the...

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...

risk assessment provides the possibility of planning and management to prevent and reduce the risk of desertification. the present study is aimed to assess the hazard and risk of desertification and to develop management programs in the semi-arid western regions of golestan province in iran. desertification rate was obtained using the iranian model of desertification potential assessment. since...

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...
