Quantitative Assessment of Land Sensitivity to Desertification in Central Sudan: An Application of Remote Sensing-Based MEDALUS Model

Land degradation sensitivity and desertification risk in Harrir region, northern Iraq

“…The ESAI utilizing the MEDALUS technique has provided valuable insights into the vulnerability of different regions to land degradation and desertification [ [18] , [19] , [20] , [21] , 49 , 51 ]. The results of the current study have been reported using a score system, which divides the locations into various groups and subclasses based on their quality.…”

“…It is made up of a comprehensive collection of indicators that provide a standardized framework for monitoring and measuring land degradation and desertification, with an emphasis on characteristics such as soil, climate, vegetation, and management index [ 17 ]. The MEDALUS model has been successfully used to quantify land degradation and desertification risk in numerous studies [ 9 , 15 , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] ].…”

“…Furthermore, remote sensing and geographic information system (GIS) technologies have shown to be useful instruments for monitoring and mapping land degradation and desertification processes over huge regions and over long time periods [ 19 , 23 , 24 , 35 ]. Satellite imaging, for example, provides vast coverage and high-resolution data, allowing for the detection and characterization of land cover changes related with land degradation [ [23] , [24] , [25] , 36 ].…”

Multispectral Satellite Image Analysis for Computing Vegetation Indices by R in the Khartoum Region of Sudan, Northeast Africa

“…Recent studies such as [46] reported frequent and severe drought periods in recent decades resulting in several cycles of famine in Sudan affecting farmers and local populations. For instance, chronic drought was reported in the Sahel region of Darfur [47], and droughts have been reported in central Sudan [48] and eastern Sudan [49,50]. Other factors include changed patterns of cloudiness and atmospheric radiation, resulting in high evapotranspiration in the extreme north near the Sahara, southern Sahel and the savannah, affecting the vegetation growth [52].…”
