Some coastal cities are sinking faster than the ocean is rising
Coastal communities face a compounding threat beyond rising sea levels: accelerated land subsidence. New research validates that densely populated coastal regions experience an average relative sea-level rise of approximately 6 millimeters annually – almost three times the global average. Contributing factors include groundwater extraction, urban development, and geological processes. This phenomenon significantly amplifies coastal vulnerability. For further exploration of related environmental challenges, see our article, "Earth’s waters are quietly running out of oxygen, scientists warn," which details a concerning decline in oceanic oxygen levels.
Assessing multi-decadal shoreline change and future sea level projections to support coastal adaptation in Selangor, Malaysia
Coastal zones worldwide face escalating pressures from climate change and urbanization, yet the geomorphological stability of tropical coastlines remains a critical research gap. This study assesses multi-decadal shoreline change along a 250 km corridor of Selangor, Malaysia, utilizing Landsat data and the Digital Shoreline Analysis System. Results reveal localized erosion hotspots and project intensifying erosive trends by 2050, informing climate adaptation strategies.

Research on China’s green total factor productivity of aquaculture industry and its influencing factors
Assessing the green development performance of China's aquaculture industry is crucial for sustainable resource management. This study utilizes a rigorous, longitudinal analysis of panel data (2009–2023) from 38 Chinese provinces to measure Green Total Factor Productivity (GTFP) and identify key influencing factors. Employing the Super-SBM model and GML index, findings reveal significant regional disparities and highlight technological progress as a primary driver of growth, particularly in freshwater aquaculture.
