Freshwater Ecosystems in India: A Limnological Review

India’s freshwater ecosystems are vital to the country’s biodiversity, economy, and cultural heritage. This review provides a comprehensive examination of the current state of limnological research in India, focusing on the diversity, distribution, and dynamics of inland water bodies such as rivers, lakes, reservoirs, and wetlands. We explore the unique characteristics of these ecosystems, their ecological significance, and the key factors influencing their health and sustainability. The review highlights the major challenges faced by Indian freshwater systems, including pollution, habitat degradation, invasive species, and the impacts of climate change. Additionally, we assess the progress made in conservation and management efforts, identifying gaps in knowledge and areas requiring further research. By synthesizing existing studies, this review aims to enhance our understanding of India’s freshwater ecosystems and support the development of effective strategies for their protection and restoration.
