This book discusses current knowledge and challenges with the ecological management and conservation of wetlands, with a focus on the East Kolkata Wetlands of India. This area is referred to as a Ramsar Site, a designation given to areas with special protection statuses, since it is the largest natural waste recycling system in the world. The site faces many threats to its biodiversity and ecosystem functioning due to anthropogenic activity in the region, and therefore an assessment of the ecosystem services, bio-ecological uniqueness, and issues stemming from climate change and human impacts is needed to develop protection strategies for the future ecological functioning and sustainability of the wetlands. The authors use GIS and remote sensing techniques to assess and monitor harmful industrial and environmental impacts on the wetlands, and to inform mitigation and conservation strategies in the face of ongoing threats such as pollution, habitat destruction and bioinvasion. Thebook also highlights various social and economic aspects tied to the functioning and management of the wetlands, along with ecological, biological, and physio-chemical considerations. The study will be of use to students and researchers in aquatic ecology, biodiversity, and environmental sustainability and conservation, as well as to environmental planners, engineers, and policymakers.

This book is part of a two-volume set that offers an innovative approach towards developing methods and tools for assigning conservation categories of threatened taxa and their conservation strategies by way of different phases of eco-restoration in the context of freshwater river systems of tropical bio-geographic zones. The set provides a considerable volume of research on the biodiversity component of river ecosystems, seasonal dynamics of physical chemical parameters, geo-hydrological properties, types, sources and modes of action of different types of pollution, river restoration strategies and methodologies for the ongoing ecological changes of river ecosystems. Volume 1 provides an in-depth analysis of different theories with international relevance pertaining to the functioning of river ecosystems, shaping their structure and contributing ecological services, and includes the principles of riverine ecology such as biogeochemical cycles, physiography, hydrogeology, and physico-chemical parameters. It covers the basic concepts and principles of water within riverine ecosystems, and the underlying ecological principles operating to ensure ecological stability and sustainability of the fluvial ecosystem. The book explains the ecofunctionality of different geo-morphological, geo-hydrological and physico-chemical factors and processes in changing time scales and spaces, with special emphasis on the tropical fresh water rivers in India.
