This paper presents and validates a novel fractional Eulerian dispersion model based on Hausdorff derivatives, which effectively simulates anomalous pollutant transport in the planetary boundary layer by incorporating a fractal dimension parameter and demonstrates superior performance over classical approaches under complex turbulent conditions.
This study uses a high-resolution triple-nested model to demonstrate that the desiccation of Lake Victoria 17,000 years ago was primarily driven by regional climate responses to reduced greenhouse gases, cooler temperatures, and altered insolation, which collectively disrupted moisture convergence and collapsed the lake's characteristic precipitation cycles rather than by remote forcing.
This study evaluates the climate resilience of hybrid wind–solar energy systems in southeastern Iraq using CMIP6 projections, revealing that future reliability risks are primarily driven by a significant decline in wind power density rather than changes in solar resources or wind–solar complementarity.
This study reveals that while the northeast monsoon influences the stability of metal-organic complexes in Mersing's coastal waters—requiring longer UV irradiation to break down ligands in August 2020 compared to April 2021—the total concentrations of dissolved Zn²⁺, Cd²⁺, Pb²⁺, and Cu²⁺ remained consistent throughout the water column in both periods due to the solubilizing effect of organic ligands.
This study integrates multi-temporal satellite imagery and high-resolution UAV surveys to reconstruct surface-restoration trajectories in the Pingquan mining cluster, revealing that while degradation has declined and restoration persistence has improved, degradation still significantly outweighs recovery, thereby providing a validated framework for differentiated management that distinguishes between observable surface-cover improvements and deeper ecosystem recovery.
This study utilizes the RUSLE model integrated with GIS and remote sensing to estimate annual soil loss in the Zarkent massif of Uzbekistan from 2015 to 2024, revealing that while 99% of the area experiences low erosion, severe hotspots exceeding 40 t·ha⁻¹·yr⁻¹ exist and require targeted conservation measures, despite limitations regarding field validation and gully erosion exclusion.
This study utilizes a mixed-methods approach combining remote sensing and household surveys to reveal that rapid, unregulated urban expansion in Rwanda's Rubavu District between 2013 and 2023 caused a 24.8% loss of agricultural land and severe livelihood disruptions for farming households, driven by weak governance and inadequate compensation mechanisms.
This study reconstructs missing daily mean air temperature data for the Arctowski Station (1977–2025) using ERA5 reanalysis and regression models, revealing significant local variability and alternating warming/cooling periods without a statistically significant long-term trend, while noting increased climate oceanity.
This study proposes a comprehensive methodological framework integrating multiple quantitative models to analyze and optimize regional collaborative carbon emission reduction pathways across the 108 cities of China's Yangtze River Economic Belt, identifying distinct basin-specific growth patterns and optimal scenarios to balance efficiency with practical implementation.
This study utilizes GIS and remote sensing to reveal that while aggregate ecosystem service values in Wadi Jazan, Saudi Arabia, increased by 7% between 2000 and 2022 due to vegetation gains in uplands, this masked significant ecological degradation driven by rapid urbanization and agricultural loss in coastal zones, underscoring the necessity for spatially explicit, watershed-scale planning to balance development with ecological resilience.
