Spatial-temporal examination and environmental preservation of the Thal and Cholistan deserts

The Thal and Cholistan Deserts in Pakistan are ecologically significant yet face numerous environmental challenges, including desertification, vegetation decline, and water scarcity. This study aims to assess the spatial-temporal dynamics and environmental challenges of these deserts through a multi-disciplinary approach. A combination of remote sensing, field surveys, and socio-economic assessments was employed. Multispectral satellite imagery from 2015 to 2023 was analyzed to detect land-use and land-cover changes, while vegetation indices such as NDVI and EVI were used to monitor vegetation dynamics. Soil and water samples were analyzed for degradation patterns, and household surveys assessed socio-economic impacts. The study revealed a 43% increase in built-up areas and a corresponding decline of 8% in vegetation cover in the Cholistan Desert, with similar trends in Thal. Groundwater levels declined by 1.5 meters per decade, and soil erosion rates were highest in areas with sparse vegetation. Socio-economic surveys showed that 70% of Cholistan households and 65% of Thal households rely on livestock and agriculture, respectively, highlighting community vulnerability to environmental changes. The findings underscore the critical impact of anthropogenic activities, overgrazing, and climate variability on these ecosystems. Sustainable management strategies integrating scientific and traditional knowledge are essential to mitigate these challenges and ensure ecosystem resilience.
