Salinity intrusion has become a critical threat to agricultural stability and water resource management in the Vietnamese Mekong Delta (VMD), particularly in coastal regions. This study evaluates the efficacy of the Long Short-Term Memory (LSTM) neural network, a sophisticated deep learning (DL) architecture, for predicting salinity concentrations...

Mining activities significantly alter environmental conditions by increasing atmospheric aerosol loads and degrading water quality. This study employs Google Earth Engine (GEE) to analyze spatiotemporal anomalies in Aerosol Optical Depth (AOD), PM₂.₅ concentrations, chlorophyll-a levels, and turbidity in Tonk, Rajasthan, between 2016 and 2022. Data...

Drought is a recurrent hazard in the Vietnamese Mekong Delta (VMD), with major implications for agriculture, water resources, and rural livelihoods. This study assesses drought variability in Kien Giang Province, Vietnam, from 1992 to 2024 using two multiscale indicators: the Multivariate Standardized Precipitation Index (MSPI) and the Multivariate...

Sustainable use of biodiversity in the Sundarbans- the world’s largest mangrove forest shared between Bangladesh and India has become increasingly complex due to rising climatic and livelihood pressures. There has been a general agreement that traditional ecological knowledge (TEK) is key to supporting ecosystem services (ES) and community...

Suspended sediment concentration (SSC) and sediment flux (SF) are critical indicators of sediment delivery in the Lower Mekong and underpin deltaic geomorphic stability and ecosystem services. With recent evidence of declining sediment supply caused by upstream regulation and intensive in-channel extraction, there is a pressing need for...

Fluvial sediment fluxes are reshaping coastal water colour, geomorphology, and ecological processes, yet schemes based on single-river loads or shoreline change may miss land-sea responses. We combine SSC records from 19 river stations across nine Chinese basins (2004-2024) with MODIS reflectance to characterize clearing, brightening, regional...

Changes in land use over space and time are key drivers of water pollution. However, current studies on landuse–water-quality relationships in small watersheds are insufficient to support regional development. Comparative research across large-scale watersheds can better inform water environmental protection, yet such studies remain limited. This...
