- Abstract
Desertification is recognised as land degradation in arid, semi-arid, and dry subhumid regions, typically resulting from climatic fluctuations and human activities, and essentially translates to a reduction in land productivity. Therefore, dynamic shifts in vegetation cover can be viewed as indicators of this land degradation and desertification. This study attempted to illuminate the dynamics of vegetation within Govi-Sumber province, a crucial ecotone zone highly vulnerable to land degradation, over the period 2010-2020 using remote sensing techniques. The normalised difference vegetation index (NDVI) was calculated using Landsat 7 and 8 satellite images to determine changes in vegetation cover. Our findings revealed a tendency towards an increase in vegetation cover in recent years, with a mean NDVI of 0.34 observed from 2010 to 2020. In previous years, sparse vegetated areas were prevalent throughout the province, but showed a steady decrease by 2020. On the contrary, densely vegetated areas progressively expanded, while ranges of 0-0.1, 0.3-0.4 and above 0.7 showed no discernible changes. The northern territory, characterised by wet depressions, exhibited the most significant transformations, with NDVI values increasing in recent years. However, the southern and northwest regions recorded significant changes, showing a downward trend in their NDVI values.
