Assessing environmentally sensitive land to desertification using MEDALUS method in Mongolia

Desertification is a global phenomenon caused by various processes, including climate change, vegetation processes, and human activities. The need to combat desertification is increasing in many countries. A reasonable assessment of the vulnerability or sensitivity of land cover to desertification a...

Mongolia’s area with the highest ESAI range increased approximately five times, indicating rapid desertification occurring throughout Mongolia from 2003 to 2008.http://dx.doi.org/10.1080/21580103.2019.1667880desertificationmedalus methodmongolialand degradationland sensitivity
