This book highlights the multi-pronged strategy for achieving sustainable rural domestic water supply in India. It deepens the understanding of groundwater (predominant source of water supply) behaviour in response to natural processes in different geological settings, analyses the factors influencing the performance of water supply schemes; identifies the conditions under which groundwater-based drinking water sources become sustainable, suggests measures for improving the sustainability of drinking water wells in hard rock regions (covering 2/3rd of India’s geographical area), presents a decision-making framework for planning rural water supply schemes in the country for ensuring long-term sustainability, and suggests physical strategies and policy measures for achieving them. The analyses for development and validation of various models that explain groundwater system behaviour and performance of rural water supply schemes are undertaken for different geological settings in Maharashtra, as the state represents a microcosm of the various hydrological, topographical, and geohydrological conditions encountered in the country. The final analysis for proposing nation-wide strategies considers the various hydrological, geological, geohydrological, and topographical and climatic settings and groundwater contamination and pollution in the country.
This book examines the concept of neighbourhood over space and time and understands how neighbourhoods can impact human health and well-being. It discusses the identification of neighbourhood boundaries, features of individual neighbourhoods, and the concept of neighbourhood in some major world as well as Indian cities. Based on extensive research, this study refers to both primary as well as secondary sources of data using various statistical and geo-spatial techniques. The first section of the book focuses on the concept of neighbourhood, concept of neighbourhood unit, methods used in the identification of neighbourhood boundaries and theories related to neighbourhood effects on health. The subsequent section of the book deals with a case study on neighbourhood effects on health in an Indian city. The case study is followed by a comparison of its results with other global studies. This book will be useful to the departments of Geography, Public Health, Sociology and Social Work. It will also be of use to professionals and practitioners like city planners, architects, NGOs, Environmentalists, and urban policy makers.
With a rapidly expanding economy many changes are taking place in India today. The business-as-usual (BAU) scenario, which assumes the continuation of current trends of key water demand drivers, will meet the future food demand. However, it leads to a severe regional water crisis by 2050, where many river basins will reach closure, will be physically water-scarce and will have regions with severely overexploited groundwater resources. While the alternative scenarios of water demand show both optimistic and pessimistic water futures, the scenario with additional productivity growth is the most optimistic, with significant scope for reducing future water demand.
This book comprises select papers presented at the International Conference on Trends and Recent Advances in Civil Engineering (TRACE 2018). The book covers inter-disciplinary research and applications in integrated water resource management, river ecology, irrigation system, water pollution and treatment, hydraulic structure and hydro-informatics. The topics on water resource management include technological intervention and solution for climate change impacts on water resources, water security, clean water to all, sustainable water reuse, flood risk assessment, interlinking of rivers and hydro policy. The contents of this book will be useful to researchers and professionals working in the field of water resource management and related policy making.
A common characteristic of water demand in urban areas worldwide is its inexorable rise over many years; continued growth is projected over coming decades. The chief influencing factors are population growth and migration, together with changes in lifestyle, demographic structure and the possible effects of climate change (the detailed implications of climate change are not yet clear, and anyway will depend on global location, but must at least increase the uncertainty in security of supply). This is compounded by rapid development, creeping urbanization and, in some places, rising standards of living. Meeting this increasing demand from existing resources is self-evidently an uphill struggle, particularly in water stressed/scarce regions in the developed and developing world alike. There are typically two potential responses: either "supply-side" (meeting demand with new resources) or "demand-side" (managing consumptive demand itself to postpone or avoid the need to develop new resources). There is considerable pressure from the general public, regulatory agencies, and some governments to minimise the impacts of new supply projects (e.g. building new reservoirs or inter-regional transfer schemes), implying the emphasis should be shifted towards managing water demand by best utilising the water that is already available. Water Demand Management has been prepared by the academic, government and industry network WATERSAVE. The concept of the book is to assemble a comprehensive picture of demand management topics ranging from technical to social and legal aspects, through expert critical literature reviews. The depth and breadth of coverage is a unique contribution to the field and the book will be an invaluable information source for practitioners and researchers, including water utility engineers/planners, environmental regulators, equipment and service providers, and postgraduates. Contents Water consumption trends and demand forecasting techniques The technology, design and utility of rainwater catchment systems Understanding greywater treatment Water conservation products Water conservation and sewerage systems An introduction to life cycle and rebound effects in water systems Developing a strategy for managing losses in water distribution networks Demand management in developing countries Drivers and barriers for water conservation and reuse in the UK The economics of water demand management Legislation and regulation mandating and influencing the efficient use of water in England and Wales Consumer reactions to water conservation policy instruments Decision support tools for water demand management
This text is written by a number of authors from different countries and disciplines, affording the reader an invaluable and unbiased perspective on the subject of intensive groundwater development. Based on information gathered from the experience of many countries over the last decades, the text aims to present a clear discussion on the conventional hydrogeological aspects of intensive groundwater use, along with the ecological, legal, institutional, economic and social challenges. Divided into two main sections, the first group of authors put forward the positive and negative aspects of intensive groundwater use, whilst a second group provide an overview of the situation specific countries face as a consequence of this phenomenon. Fully revised and up-to-date, Groundwater Intensive Use makes a significant number of discoveries in a subject area that is topical in today's climate.
This book discusses, the issues with respect to consumption of water by the marginalised (poor) sections of the society and the efficacy of using pricing policy as a tool for overall demand management of household water. It includes a case study based on the survey of the municipal water supply in Delhi. It covers water scenario at the national level, suggesting regulatory framework and reforms for the efficient urban water management in India. There are several conflicts around the water resource such as - equitable access; competing uses; issue of quality and availability; commercialisation and privatisation, the book provides an outline for their resolution. The authors examine urban water management in relation to - reach of municipal water supply to households; price sensitivity of different income groups; consumption pattern amongst various sources; conservation efforts and public private partnership.
