Book Description
This new volume examines the ecological importance, threats, protection, and management of the biodiversity of freshwater ecosystems, such as lakes, ponds, rivers, streams, reservoirs, pools, and wetlands. As populations have been increasing exponentially, humans are using freshwater ecosystems severely, resulting in habitat destruction and breakdown. Environmental contamination, climate change, the introduction of harmful and invasive organisms, unplanned dredging and de-weeding processes, disposal of sewer systems in freshwater bodies, and badly planned water diversions are the leading causes of habitat loss in freshwaters. These impacts have led to significant decreases in the numbers and productivity of many freshwater species and decreased biodiversity in freshwater. This book presents a selection of primary research and review papers on several freshwater aquatic biodiversity studies, which involve evaluating plants, macroinvertebrates, macrophytes, benthic zones, and fish diversity in freshwater ecosystems. It provides an abundance of new information on freshwater biodiversity distribution, status, and patterns. Key features: Discusses the importance, threats, and management of biodiversity of freshwater ecosystems Provides detailed coverage of modern and updated techniques used in the evaluation and conservation of freshwater biodiversity Looks at the impact of pesticides pollution on freshwater environs, and on aquatic and terrestrial life Reviews how global climate change affects freshwater biodiversity Biodiversity of Freshwater Ecosystems: Threats, Protection, and Management promotes the enhancement and strengthening of freshwater protection and its unique biodiversity for scientists, policymakers, scholars, researchers, NGOs, and the public, providing necessary background knowledge and practical tools to help manage aquatic ecosystems and their biodiversity in a holistic manner.

Book Description
This new volume addresses the environmental impacts of pollution on freshwater aquatic ecosystems and presents sustainable management and remediation practices and advanced technology help to address the different types of pollutants. Freshwater Pollution and Aquatic Ecosystems: Environmental Impact and Sustainable Management considers the need for sustainable, efficient, and cost-effective tools and technologies to assess, monitor, and properly manage the increasing issues of aquatic pollution. It provides detailed accounts of the phenomena and mechanisms related to aquatic pollution and highlights the problems and threats associated with pollution contamination in freshwater. It provides useful insight into the sustainable and advanced pollution remediation technology adopted by different countries for the monitoring, assessment, and sustainable management of pollution. The chapters in the volume evaluate the sources of harmful pollutants, which include industrial effluents, sewage, and runoff from agricultural industries, which result in toxic microbes, organic waste, oils, and high load of nutrients. Unsustainable management practices of domestic sewage and indiscriminate use of chemical pesticides lead to the technological disturbance of aquatic biota. In addition to harming aquatic biota, these pollutants find their way into the human body through inhalation, ingestion, or absorption and finally tend to bio-accumulate in trophic levels of the food chain, which poses a major risk to human beings. This book will be a valuable resource for ecologists, environmentalists, scientists, and many others for their work in understanding and management of aquatic pollutants in freshwater biospheres.

Book Description
Volume 2: Handbook of Spatio-Temporal Monitoring of Water Resources and Climate is aimed to describe the current state of knowledge and developments of geospatial technologies (Remote Sensing and Geographic Information Systems) for assessing and managing water resources under climate change. It is a collective achievement of renowned researchers and academicians working in the Hindu Kush Himalayan (HKH) mountain range. The HKH region is a part of the Third Pole outside the polar regions due to its largest permanent snow cover. Importantly, the Himalayan belt is geologically fragile and vulnerable to geohazards (e.g. landslides, land subsidence, rockfalls, debris flow, avalanches, and earthquakes). Therefore, critical assessment and geospatial solutions are indispensable to safeguard the natural resources and human beings in the Himalayas using space-borne satellite datasets. This book also showcases various remote sensing techniques and algorithms in the field of urban sprawling, urban microclimate and air pollution. The potential impacts of climate change on the cryosphere and water resources are also highlighted. This comprehensive Handbook is highly interdisciplinary and explains the role of geospatial technologies in studying the water resources of the Himalayas considering climate change. Key Features This book is unique as it focuses on the utility of satellite data for monitoring snow cover variability, snowmelt runoff, glacier lakes, avalanche susceptibility and flood modeling. Explain how Remote Sensing techniques are useful for mapping and managing the morphology and ecology of the Himalayan River. Addresses how geospatial technologies are valuable for understanding climate change impact on hydrological extremes, the potential impact of land use/land cover change (LULC) on hydrology and water resources management. It highlights the impact of LULC changes on land surface temperature, groundwater, and air pollution in urban areas. Includes contributions from global professionals working in the HKH region. Readership The Handbook serves as a valuable reference for students, researchers, scientists, Hydrologists, hydro-ecologists, meteorologists, geologists, decision makers and all others who wish to advance their knowledge on monitoring and managing water resources and urban ecosystem using remote sensing in the HKH region considering climate change.

Book Description
Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia's great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely to cause significant changes in water availability over the next several decades, but other factors, including groundwater depletion and increasing human water use, could have a greater impact. Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies. Himalayan Glaciers: Climate Change, Water Resources, and Water Security makes recommendations and sets guidelines for the future of climate change and water security in the Himalayan Region. This report emphasizes that social changes, such as changing patterns of water use and water management decisions, are likely to have at least as much of an impact on water demand as environmental factors do on water supply. Water scarcity will likely affect the rural and urban poor most severely, as these groups have the least capacity to move to new locations as needed. It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities. As living standards and populations rise, water use will likely increase-for example, as more people have diets rich in meat, more water will be needed for agricultural use. The effects of future climate change could further exacerbate water stress. Himalayan Glaciers: Climate Change, Water Resources, and Water Security explains that changes in the availability of water resources could play an increasing role in political tensions, especially if existing water management institutions do not better account for the social, economic, and ecological complexities of the region. To effectively respond to the effects of climate change, water management systems will need to take into account the social, economic, and ecological complexities of the region. This means it will be important to expand research and monitoring programs to gather more detailed, consistent, and accurate data on demographics, water supply, demand, and scarcity.
