Rainwater harvesting for water security in Uzbekistan: a social-ecological systems analysis

This study employs a social-ecological systems framework to demonstrate that while rainwater harvesting is biophysically feasible and beneficial for agricultural sustainability in Uzbekistan, its low adoption stems primarily from institutional path dependence and resource constraints rather than technical limitations, necessitating policy reforms focused on land tenure, financial support, and extension services to scale the technology effectively.

Assessing Land Productivity Using Normalized Difference Vegetation Index and Key Environmental Drivers in Dewgain, Rural India

This study assesses land productivity in Dewgain, rural India, by integrating Sentinel-2 derived NDVI with climatic and soil data to reveal that while vegetation trends are non-significantly declining, rainfall and soil organic carbon are key drivers of productivity, with nearly half the area classified as low-productivity zones requiring sustainable management.

Permeability Evolution and Cross-Specimen Machine-Learning Prediction of Geothermal-Reservoir Sandstone under Coupled Temperature and Pressure

This study develops a robust machine-learning framework using nested specimen-grouped cross-validation to predict the path-dependent permeability of geothermal-reservoir sandstone under coupled temperature and pressure, identifying random forest as the optimal model and highlighting confining pressure as the most stable predictive factor while demonstrating incomplete permeability recovery after unloading.

Long-Term Migration of Plutonium and Americium in Soil: A Multi-Year Laboratory Lysimeter Study

This multi-year laboratory lysimeter study on German agricultural soil reveals that while americium exhibits negligible upward migration over five years, plutonium demonstrates significant capillary-driven movement toward the soil surface, challenging current radioecological models that often overlook this pathway.

North Atlantic SST Drives Sub-seasonal Variability and Predictability of the Large-Scale Circulation

This study demonstrates that North Atlantic sea surface temperature patterns actively drive sub-seasonal atmospheric circulation, with specific regimes—particularly one favoring atmospheric blocking—significantly extending weather predictability beyond the typical two-week limit.

Interannual Variability of Chlorophyll-a in the Southeastern Arabian Sea: Impacts of the Tropical Easterly Jet and Indian Ocean Dipole

This study utilizes 2003–2023 satellite and reanalysis data to demonstrate that the interannual variability of Chlorophyll-a in the Southeastern Arabian Sea during the summer monsoon is primarily driven by the combined effects of the Tropical Easterly Jet and Indian Ocean Dipole, which modulate local winds, upwelling dynamics, and coastal wave propagation to trigger anomalous phytoplankton blooms.

Regional contrasts in extreme precipitation intensity and wet-day occurrence across Northeast China during 1990-2022

This study analyzes 1990–2022 data from 252 stations in Northeast China to reveal that while extreme precipitation intensity has generally increased across the region, wet-day occurrence shows weaker and spatially mixed changes, highlighting the need to distinguish between event magnitude and frequency for accurate hazard assessment.

Groundwater potential mapping of the Imiter region, Anti-Atlas, Morocco

This study utilizes a GIS-based multi-criteria decision analysis framework integrating remote sensing, morphostructural, and radiometric data to map groundwater potential zones in the arid Imiter region of Morocco, revealing that fractured corridors and hydrothermally altered domains are the primary controls on groundwater favorability and validating the model's accuracy through airborne radiometric ratios.
