The results showed that the dustfall particles sampled in the Taklimakan hinterland were mostly micro-aggregates, angular, and subrounded based on the statistical analysis of the Focused Ion Beam Scanning Electron Microscope (FIB-SEM). As determined by the Laser Diffraction Particle Size Analyzer (LDPSA), the dustfall particles were predominately coarse particles, with particles between 20 μm and 80 μm accounting for 83.73 % of the total particle number. Volume proportion of dustfall particles with particle size of 60–150 μm was 72.41 %. Mineralogical analysis of dustfall particles using the Intelligent Scanning Electron Microscope Environmental Particle Analysis System (IntelliSEM EPAS) revealed that calcite was the dominant component (31.15 %), followed by quartz (18.52 %), chlorite (11.84 %), kaolinite (8.11 %), smectite (6.28 %), and illite (5.25 %). Halite was identified as the primary salt component, making up 9.52 % of detected particles.

Land use transitions mainly occur from ecological lands to agricultural and urban areas. The reduction in ecological space is largely driven by the conversion of grasslands and forests to agricultural and industrial lands, particularly in core urban areas and their surrounding zones. Ecological environment quality in Wuwei exhibits both improvement and degradation, with regional variations. The primary positive change results from converting agricultural lands and grasslands into forests.

Buffer zones of 10, 20, and 50 km around key river systems particularly the Nile, Draa, and Medjerda—were analyzed to evaluate spatial relationships between water access, population density, and agricultural vulnerability. The findings reveal that the 10 km buffer zone around the Nile has undergone 45 % population increase between 2000 and 2020, placing extraordinary pressure on freshwater resources and irrigated agriculture. Libya and Algeria exhibit high hydrological vulnerability, lacking perennial rivers and relying on groundwater extraction, while Morocco and Tunisia face spatially uneven water access. GIS-based zonal statistics show that regions closest to rivers not only host the densest populations but also experience the highest evapotranspiration and land-use change. Over 60 % of North Africa's landmass is classified as high or very high risk for water stress and agricultural decline, particularly in dryland zones beyond 20 km from rivers. The study underscores the critical role of rivers in structuring settlement and farming patterns, while also identifying emerging hotspots of environmental degradation in interior drylands.
