Abstract

The Meghna River, vital for Bangladesh’s ecosystems and livelihoods, faces threats from urbanization, agriculture, industrialization, pollution, and climate change. This study examines the basin’s spatio-temporal dynamics, focusing on hydro-physico-chemical properties (temperature, pH, dissolved oxygen, salinity) and bio-resources (phytoplankton, zooplankton, and benthic macroinvertebrates). Field surveys, laboratory analyses, and satellite imagery revealed consistent patterns, highlighting the ecosystem’s vulnerability and the urgent need for conservation strategies to sustain ecological balance and livelihoods.
