Summary
This review synthesises evidence on anthropogenic sources of watershed pollution—particularly agricultural runoff alongside industrial and urban contributions—and their degradation of aquatic ecosystems and water quality. The authors evaluate mitigation strategies spanning regulatory frameworks, sustainable farming practices, infrastructure improvements, and emerging biotechnologies, whilst emphasising the role of integrated policy frameworks and cross-sector collaboration in protecting freshwater systems.
UK applicability
The findings on agricultural runoff impacts and mitigation strategies are directly applicable to UK catchment management, particularly given the prevalence of intensive agriculture in river basins. Recommendations for sustainable farming practices and integrated water governance frameworks align with UK Water Environment Regulations and catchment partnership approaches.
Key measures
Water quality parameters; heavy metal residues; biodiversity indicators; eutrophication markers; fish population dynamics
Outcomes reported
The review examined primary sources of contamination in river catchments (industrial effluents, agricultural runoff, urban wastewater) and their effects on water quality, aquatic habitats, and biodiversity. It evaluated strategic mitigation approaches including sustainable agricultural practices, waste management regulations, wastewater treatment infrastructure improvements, and biotechnological techniques to reduce farming impacts on water quality.
