This book provides an ecosystem perspective in addressing the water resource management issues in the South Asian region. It argues that aspects such as sources of water, its distribution and users; land-water interrelations; drivers of change such as laws, policies and institutions; management of issues and technologies related to water supply; institutional set-up; economic instruments such as pricing, taxes, subsidies; and economics of ecosystem services are crucial. Climate changes, melting of glaciers and polar ice caps, rising sea level and the increased frequency of extreme events, have to be factored into integrated management of water resources. This book addresses some of these major issues related to aquatic ecosystems and focuses on three major aspects: (a) concepts related to ecosystems, ecosystem services and their linkages with water; (b) human impacts on ecosystems, particularly the aquatic ecosystems, and their assessment; and (c) the management, including policy, governance and economics. Comprising new theories, research and case studies, the book will be useful those concerned with water resource management - professionals, students and researchers.

The focus of this book is on the key water-related vulnerabilities to climate change in Africa, particularly in its most vulnerable areas, exploring potential management responses to such vulnerabilities. The African countries are particularly exposed and vulnerable to the negative impacts of climate change, with important impacts on water resources and hydrological systems, water availability, water resource management and sea level variations. Already, under various anthropogenic pressures, the status of water resources in Africa has been changing over the past decades, with decreasing water quality, falling groundwater levels, and variability in rainfall, both in terms of timing and intensity. Climate change will further accelerate the rate of change, affecting the ability of people and societies to respond in a timely manner. It is clear that there is no quick fix to the pressures imposed on water resources by climate change. Increasing the resilience of ecosystems and communities to extreme events such as flooding and drought, and integrating climate change risks and opportunities into development decision-making is indeed a key challenge, as much a technical climate-change one, as a political and developmental challenge. The book, in this regard, intends to contribute to the debate around climate change in relation to water resources management in Africa, and in particular inform policy decisions and actions that will improve governments' and communities' ability to manage the challenges of climate change and variability in relation to the aquatic ecosystems that they depend on. The knowledge collected in this book will benefit policy makers, researchers, as well as other stakeholders.

The absence of water supply infrastructure is a critical issue that affects the sustainability of cities in the developing world and the quality of life of millions of people living in these cities. Urban India has probably the largest concentration of people in the world lacking safe access to these infrastructures. This book is a unique study of the politics of water supply infrastructures in three metropolitan cities in contemporary India - Bangalore, Chennai and Kochi. It examines the process of change in water supply infrastructure initiated by notable Public Private Partnership's efforts in these three cities to reveal the complexity of state-society relations in India at multiple levels - at the state, city and neighbourhood levels. Using a comparative methodology, the book develops as understanding of the changes in the production of reform water policy in contemporary India and its reception at the sub-national (state) level. It goes on to examine the governance of regimes of water supply in Bangalore, Chennai and Kochi, and evaluates the role of the partnerships in reforming water supply. The book is a useful contribution to studies on Urban Development and South Asian Politics.

Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based separations, and biomedical applications through novel membrane materials. This book contains 20 chapters written by leading academic researchers on membrane fabrication and modification techniques and provides a comprehensive overview on the recent developments of membrane technology. Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.

This book examines India's transboundary river water disputes with its South Asian riparian neighbours - Pakistan, Bangladesh, Nepal and Bhutan. It explores the history of disputes and cooperation over the transboundary river water in this region as well as discusses current disputes and future concerns. It analyses how and why existing transboundary river water sharing treaties between India and its South Asian riparian neighbours are confronted with challenges. The book indicates that India's transboundary river water disputes with its South Asian riparian neighbours are likely to escalate in coming years due to the widening of the demand-supply gap in the respective countries. It further shows the impact of bilateral relations on the resolution of transboundary river water disputes, even as cordial relationships do not always guarantee the absence of river water disputes between riparian states. The book looks at some key questions: How political are India's transboundary rivers water disputes in South Asia? Why do the roots of India's river water disputes with Bangladesh and Pakistan lie in the partition of the British India in 1947? Why are there reservations against India's hydroelectricity projects or allegations of water theft? Is it possible to resolve transboundary river water disputes among these South Asian countries? This book will greatly interest scholars and researchers working in the areas of river management, environmental politics, transnationalism, water resources, politics and international relations, security studies, peace and conflict studies, geopolitics, development studies, governance and public administration, and South Asian studies in addition to policymakers and journalists.

The book presents the scientific basis for the controlled husbandry of fish, whether it be in a stream of water or a standing water pool. Part 1, Flowing Water Fish Culture, is a major revision of the author's initial book and includes greatly expanded coverage of rearing unit design criteria, fish growth and the use of liquid oxygen, hatchery effluent control, and recirculating systems. Part 2, Static Water Fish Culture, presents the scientific basis of fish culture in standing water systems including nutrient and dissolved gas dynamics, pond ecology, effects of fertilization and supplemental feeding, water quality management and representative static water aquacultures. Aquaculture Technology conveys the science in a manner appropriate for use by university students and teachers and others involved in fish production and aquaculture research and development worldwide. It will enable the reader to adapt to changing technologies, markets, and environmental regulations as they occur.

Lessons can be learnt from the past; from time to time it is useful for practitioners to look back over the historical developments of their science. Hydrogeology has developed from humble beginnings into the broad church of investigatory procedures which collectively form the modern-day hydrogeologist's tool box. Hydrogeology remains a branch of the over-arching science of geology and today provides analysis of the sub-surface part of the water cycle within a holistic approach to problem solving. The History of Hydrogeology, is a first attempt to bring the story of the evolution of the science of hydrogeology together from a country- or region-specific viewpoint. It does not cover history to the present day, nor does it deal with all countries involved in groundwater studies, but rather takes the story for specific key countries up and until about the period 1975 to 1980. This is when hydrogeology was still evolving and developing, and in some areas doing so quite rapidly. The book has been written not only for practitioners of hydrogeology and hydrology but also for teachers and students to see the context of the evolution of the science around the globe. The History of Hydrogeology will also be of interest to science historians and all those interested in the role that individuals, institutes and nations have played over the years in defining modern day studies of groundwater.

This time-saving book provides extensive coverage of all important aspects of nitrates in groundwater, ranging from prevention to problem assessment to remediation.

This volume provides readers with an opportunity to learn from front line water managers of watershed-based agencies across Canada about integrated water management (or integrated water resource management). In common with practice in much of the world, the responsibility for implementing integrated watershed management in Canada is fragmented. Each province and territory in Canada has developed unique approaches or governance models to guide decision making in that regard. Thus, this edited volume enables readers from around the world to gain insight on the best practices in Canada for achieving success and addressing barriers to implement IWM. Although there remains non consensus about how to "best" approach river basin management, some of the main observations include: There is a need to balance a focus on "the big picture", with scoping the scale and scope of planning activities in order that feasible and effective solutions can be implemented Three types of integration are popular among the agencies included in the book: (i) among environment, economy and society, (ii) interactions between people and the environment and (iii) integration (or coordination) of administrative activities. Much more attention is required to achieving effective engagement from Indigenous communities The chapters were originally published in a special issue of the International Journal of Water Resources Development.

This book will address the major subsoil physical and chemical constraints and their implications to crop production; Plant growth is often restricted by adverse physical and chemical properties of subsoils yet these limitations are not revealed by testing surface soils and hence their significance in crop management is often overlooked. The major constraints can be physical or chemical. Physical limitations such as poor/nil subsoil structure, sandy subsoils that do not provide adequate water or gravelly subsoils and, etc. On the other hand, chemical constraints include acidity/alkalinity, high extractable Al or Mn, low nutrient availability, salts, boron toxicity and pyritic subsoils. Some of these constraints are inherent properties of the soil profile while others are induced by crop and soil management practices. This aim of this book is to define the constraints and discuss amelioration practices and benefits for crop production. This book will be of interest to readers involved with agriculture and soil sciences in laboratory, applied or classroom settings.

Mathematical models are the effective tool to solve different tasks predicting pollutant movement. The finite difference method is the oldest, but still remains widely used in hydrogeological practice. However, this method is not very useful to construct the new transport models because it cannot approximate the shape of remediation elements exactly. Therefore the book is concerned with the FEM (Finite Element Method) and BEM (Boundary Element Method), and also with the comparison of advantages of these methods in groundwater hydrology. The combination of the BEM and the random-walk particle tracking method, which seems to be a very useful tool to model the spread of pollution in groundwater, are also presented. The computer programmes have been developed on the basis of the theoretical backgrounds of these methods. They use the Visual C++ programming language for Windows 95/NT platform and will be included in the book.

This book covers the full spectrum of water and environment conservation, offering management lessons, identifying the barriers to transformative change, and then presenting agendas and initiatives for sustainable global water and environment management.
