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.

Book Description
This edited book summarizes numerous research studies on remote sensing and GIS of natural resource management for the Himalaya region done by Indian Institutions and Universities over the last decade. It gives an overview of hydrometeorological studies on Himalayan water resources and addresses concerns in the development of water resources in this region, which is dealing with an increased pressure in population, industrialization and economic development. While the source of some of the major rivers of India are found in the Himalayas, the glaciers and water bodies in the region are continuously shrinking leading to a depletion of water and deterioration of water quality. This is affecting a population of up to 2.5 billion people. The ecosystems have been under threat due to deforestation, loss of biodiversity, expansion of agriculture and settlement, overexploitation of natural resources, habitat loss and fragmentation, poaching, mining, construction of roads and large dams, and unplanned tourism. Spaceborne remote sensing with its ability to provide synoptic and repetitive coverage has emerged as a powerful tool for assessment and monitoring of the Himalayan resources and phenomena. This work serves as a resource to students, researchers, scientists, professionals, and policy makers both in India and on a global level.

Book Description
The Karakoram contains the greatest concentration of glaciers and most of the largest ice masses outside high latitudes. They comprise major stores and sources of fresh water in an otherwise extreme, continental, dry region. As many as 200 million people living downstream, in the valleys of the Indus and Yarkand Rivers, depend on melt waters from snow and ice. They are at risk from climate-change impacts on glaciers and water supply, and from hazards such as glacial lake outburst floods. Useful research initiatives go back to the nineteenth century, but coverage has generally been limited geographically and has not been continuous over time. It is almost 80 years since a monograph was devoted to the Karakoram glaciers. The book presents a comprehensive overview, including statistics for the ice cover, glacier mass balance and dynamics, glacierized landscapes, rock glaciers, water resources and environmental hazards. Published glaciological and related research is surveyed along with expedition reports and archival materials in several languages. The expanding potential of satellite coverage is exploited, but conditions and processes reported from field investigations are the main focus. Previously unpublished observations by the author are presented, based on some 45 years of work in the region. Broad understanding of the glacial environment is used to address emerging concerns about the High Asian cryosphere and the fate of its glaciers. These are discussed in relation to the pressing issues of water supply, environmental risk and sustainability. Questions of what is not known help identify much needed monitoring and research. The book is of interest to researchers, professionals, and those studying glaciers, mountain environments, water resources and environmental hazards. The topics discussed should be of concern for anyone involved in regional development and global change in South and Inner Asia.

Book Description
This book analyzes the issues associated with climate change in the Himalayas. The purpose of choosing the Himalayas as a focus is because it is a particularly fragile mountain system, highly sensitive to climate change impacts, and it contains one of the largest human populations affected by climate change. The book provides extensive data and information regarding the climate history of the Himalayas, and the current effects of climate change on Himalayan weather systems, and on human and animal populations in the region. The book begins with an overview of global climate change with discussions of data trends and international initiatives, then segues into a history of climate changes and weather trends in the Himalayas. Weather systems of the Himalayas, both past and current, are analyzed and detailed through climate models, seasonal observations of weather fronts, and overviews of various climate scenarios. The book then discusses climate change impacts and signat ures specific to the Central Himalayan region, where the largest effects of impacts are observed. Readers will discover analysis presented on water resources, meteorological changes, biodiversity, agriculture and human health along with perspectives of management and policy. This book will appeal to researchers studying climate science, climatology, environmental scientists and policymakers.

Book Description
The Ganges is one of the most complex yet fascinating river systems in the world. The basin is characterized by a high degree of heterogeneity from climatic, hydrological, geomorphological, cultural, environmental and socio-economic perspectives. More than 500 million people are directly or indirectly dependent upon the Ganges River Basin, which spans China, Nepal, India and Bangladesh. While there are many books covering one aspect of the Ganges, ranging from hydrology to cultural significance, this book is unique in presenting a comprehensive inter-disciplinary overview of the key issues and challenges facing the region. Contributors from the three main riparian nations assess the status and trends of water resources, including the Himalayas, groundwater, pollution, floods, drought and climate change. They describe livelihood systems in the basin, and the social, economic, geopolitical and institutional constraints, including transboundary disputes, to achieving productive, sustainable and equitable water access. Management of the main water-use sectors and their inter-linkages are reviewed, as well as the sustainability and trade-offs in conservation of natural systems and resource development such as for hydropower or agriculture.

Book Description
Melting glaciers and the loss of seasonal snow pose significant risks to the stability of water resources in South Asia. The 55,000 glaciers in the Himalaya, Karakoram, and Hindu Kush (HKHK) mountain ranges store more freshwater than any region outside of the North and South Poles. Their ice reserves feed into three major river basins in South Asia—the Indus, Ganges, and Brahmaputra—that are home to 750 million people. One major regional driver of the accelerating glacier melt is climate change, which is altering the patterns of temperature and precipitation. A second driver may be deposits of anthropogenic black carbon (BC), which increase the glaciers’ absorption of solar radiation and raise air temperatures. BC is generated by human activity both inside and outside of South Asia, and policy actions taken by the South Asian countries themselves may meaningfully reduce it. Glaciers of the Himalayas: Climate Change, Black Carbon, and Regional Resilience investigates the extent to which the BC reduction policies of South Asian countries may affect glacier formation and melt within the context of a changing global climate. It assesses the relative impact of each source of black carbon on snow and glacier dynamics. The authors simulate how BC emissions interact with projected climate scenarios. They also estimate the extent to which these glacial processes affect water resources in downstream areas of these river basins and present scenarios until 2040. Their policy recommendations include the following: Full implementation of current BC emissions policies can significantly reduce BC deposition in the region; additional reductions can be realized by enacting and implementing new policies that are economically and technically feasible. Improving the efficiency of brick kilns could be key to managing BC, and modest up-front investments could pay off quickly. Cleaner cookstoves and cleaner fuels can help to reduce BC and improve local air quality. Improving institutions for basin-based water management and using price signals are essential elements of more efficient water management. Careful management of hydropower and storage resources will require developers to factor in changing water flows and consider planning for large storage projects to stabilize water availability. Regional cooperation and the exchange of information can be an effective transboundary solution, helping countries to manage glaciers and related natural assets collaboratively. New policies are needed to reverse trends like the melting of glaciers. Success will require an active, agile cooperation between researchers and policy makers. To support an open dialogue, the model developed and used in this book is an open-source, state-of-the-art model that is available for others to use and improve on.
