Soil Salinity Variations and Associated Implications for Agriculture and Land Resources Development Using Remote Sensing Datasets in Central Asia

Global agricultural lands are becoming saline because of human activities that have affected crop production and food security worldwide. In this study, the spatiotemporal variability soil electrical conductivity (EC) in Central Asia was evaluated based on high-resolution multi-year predicted EC data, Moderate Resolution Imaging Spectroradiometer (MODIS) land cover product, precipitation, reference evapotranspiration, population count, moisture datasets. We primarily detected pixel-based trends over past three decades correlated with potential deriving factors. The results showed an overall increase salt-affected areas between 1990 2018 for different types. trend increased by 6.86% (p < 0.05) during 1990–2018. open shrub dominated woody perennials experienced highest increasing salinity trend, particularly Uzbekistan Turkmenistan local areas, while there a decreasing cropland such as Bukhara Khorezm (Uzbekistan). main factors affect were strongly associated pressure evapotranspiration. This study provides comprehensive variations from to regional scales. Agriculture resource managers must tackle rising degradation concerns caused changing climate arid utilise geoinformatics.
