Earth-Observation Mapping of a Wastewater-Fed Wetland for Sustainable Water Resources Management in a Ramsar Site: The East Kolkata Wetlands

This study develops a high-accuracy, hierarchical land-use/land-cover mapping framework using Sentinel-2 imagery and Random Forest classification to distinguish fine-scale water-dependent classes within the East Kolkata Wetlands, thereby enabling sustainable wastewater management, flood buffering, and encroachment control in this critical Ramsar site.

The multi-dimensional impacts of grazing on grassland ecological quality based on meta-analysis

This meta-analysis of 585 cases reveals that while grazing generally negatively impacts grassland vegetation and soil quality, moderate grazing intensity optimizes ecosystem functions by maximizing soil and vegetation indicators, whereas high intensity leads to significant declines in biomass, nutrients, and soil health.
