Satellite Remote Sensing Reveals Climate‐Driven Breeding Failure in Greater Flamingos at a Mediterranean Hypersaline Lake

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Hypersaline lakes are shrinking worldwide, yet how desiccation drives breeding failure in dependent waterbirds remains poorly quantified over multi‐decadal timescales. Tuz Gölü (Lake Tuz, Türkiye) supports the largest Greater Flamingo (Phoenicopterus roseus) breeding colony in the Eastern Mediterranean, contributing up to 67% of regional chick

Urban expansion and wetland shrinkage estimation using QGIS- tool: A Kolkata Case-Study [PDF]

EPJ Web of Conferences
Urban wetlands are important natural reservoirs that help to regulate water cycles, weather and the environment at large in rapidly growing cities. Unfortunately, the fast pace of urban growth has led to the loss of many of these natural habitats.

Drought severity estimation using NDWI index in Parbhani district of Maharashtra

Journal of Agrometeorology
The study was carried out to investigate the impact of drought on vegetation in Maharashtra's Parbhani district, utilizing remote sensing techniques. Analysis of Landsat 8 data for 2015 (a drought year) and 2020 (a normal year) reveals fluctuations in the Normalized Difference Water Index (NDWI) closely correlated with rainfall patterns.

A Comparison of Land Surface Water Mapping Using the Normalized Difference Water Index from TM, ETM+ and ALI

Remote Sensing, 2013
Remote sensing has more advantages than the traditional methods of land surface water (LSW) mapping because it is a low-cost, reliable information source that is capable of making high-frequency and repeatable observations.

Fluvio-geomorphic change of the Padma-Meghna river course using the NDWI and MNDWI techniques

Water Science
Abstract This study intends to investigate the fluvial-geomorphic change and erosion-accretion processes of two significant rivers. The 2149 km2 research area's overall erosion and accretion were depicted using multi-temporal Landsat images and NDWI, MNDWI methods to measure and investigate change.
