Water Implications Of Biofuels Production In The United States
by National Research Council of the National AcademiesNational interests in greater energy independence, concurrent with favorable market forces, have driven increased production of corn-based ethanol in the United States and research into the next generation of biofuels. The trend is changing the national agricultural landscape and has raised concerns about potential impacts on the nation's water resources. To help illuminate these issues, the National Research Council held a colloquium on July 12, 2007 in Washington, DC. <i>Water Implications of Biofuels Production in the United States</i>, based in part on discussions at the colloquium, concludes that if projected future increases in use of corn for ethanol production do occur, the increase in harm to water quality could be considerable from the increases in fertilizer use, pesticide use, and soil erosion associated with growing crops such as corn. Water supply problems could also develop, both from the water needed to grow biofuels crops and water used at ethanol processing plants, especially in regions where water supplies are already overdrawn. The production of "cellulosic ethanol," derived from fibrous material such as wheat straw, native grasses, and forest trimmings is expected to have less water quality impact but cannot yet be produced on a commerical scale. To move toward a goal of reducing water impacts of biofuels, a policy bridge will likely be needed to encourage growth of new technologies, best agricultural practies, and the development of traditional and cellulosic crops that require less water and fertilizer and are optimized for fuel production.
Water Issues in Himalayan South Asia: Internal Challenges, Disputes and Transboundary Tensions
by Amit RanjanThe book looks into the domestic water issues and disputes in the Himalayan South Asian countries, and based on it analyzes trans-boundary water disputes. Himalayan South Asia comprises India, Pakistan, Bangladesh, Nepal, Bhutan, and Afghanistan. All except Afghanistan share river waters with India. Home to some of the major river basins of the world, a part of this region falls into water scarce zone, and according to the United Nations Water Report of 2018 some of them will experience severe water scarcity by 2050.The book also studies water issues in China. Though the country is not a part of the Himalayan South Asia, most of the major rivers of this region originate in China. Over the years, China has been alleged by countries like India for diverting, choking or using the trans-boundary river waters for its purpose. Understanding water competition and issues in China will help one to understand its transboundary water behavior.
Water Justice and Groundwater Subsidies in India: Equitable and Sustainable Access and Regulation (Earthscan Studies in Water Resource Management)
by Gayathri D. NaikThis book examines the impact of water-related subsidies on social and distributive equity and environmental sustainability in groundwater access and regulation in India.This book argues that adopting a water justice framework is essential to ensure equitable and sustainable access to and regulation of groundwater by balancing anthropogenic and ecological water needs. The inherent inequity resulting from property rights-controlled groundwater access gets widened by the social, political, and economic factors determining the subsidy beneficiaries. Adopting a socio-legal approach, this book draws on two contrasting case studies in India: Kerala, a water-secure state, and Rajasthan, an arid state. Arguing for a shift to a new paradigm in water governance, it critically examines the feasibility of the public trust doctrine and rights of nature discourse to analyse the best suitable regulatory framework that can balance the human right to water and ecological sustainability in groundwater resources. It demonstrates the feasibility of adopting various environmental law principles that balance human rights to water and nature. It argues that the hitherto highlighted public trust doctrine cannot address these inequities due to its anthropogenic bias and property rights link. This book examines the applicability of the rights of nature discourse instead of these property rights-based regulations to incorporate and mainstream the concerns of aquifer protection in water governance.This book shall be of great interest to students, scholars, and practitioners of water law and policy, environmental law, water and social justice, development studies, and political ecology.

Water Loss Assessment in Distribution Networks: Methods, Applications and Implications in Intermittent Supply (IHE Delft PhD Thesis Series)
by Taha M. Al-WashaliWater utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for rethinking the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent supply networks. Water loss assessment methods were originally developed in continuous supply systems, and their application in intermittently operated networks (in developing countries) is hindered by the widespread use of household water tanks and unauthorised consumption. This study provides an extensive review of existing methods and (software) tools for water loss assessment. In addition, several new methods were developed, which offer improved water loss assessment in intermittent supply. As the volume of water loss varies monthly and annually according to the amount of supplied water, this study proposes procedures to normalise the volume of water loss in order to enable water utilities to monitor and benchmark their performance on water loss management. The study also developed a novel method of estimating apparent losses using routine data of WWTP inflows, enabling future real-time monitoring of losses in networks. Different methods have also been suggested to estimate the unauthorised consumption in networks. This study found that minimum night flow analysis can still be applied in intermittent supply if an area of the network is supplied for several days. Furthermore, this study concluded that water meter performance is enhanced in intermittent supply conditions. However, continuous supply in the presence of float-valves significantly reduces the accuracy of water meters. Finally, this study provides guidance and highlights several knowledge gaps in order to improve the accuracy of water loss assessment in intermittent supply. Accurate assessment of water loss is a prerequisite for reliable leakage modelling and minimisation as well as planning for, and monitoring of water loss management in distribution networks.
Water Management Challenges in Global Change: Proceedings of the 9th Computing and Control for the Water Industry (CCWI2007) and the Sustainable Urban Water Management (SUWM) conferences, Leicester, UK, 3-5 September 2007
by Bogumil Ulanicki; Kalanithy Vairavamoorthy; David Butler; Peter L.M. Bounds; Fayyaz Ali MemonWater Management Challenges in Global Change contains the proceedings of the 9th Computing and Control for the Water Industry (CCWI2007) and the Sustainable Urban Water Management (SUWM2007) conferences. The rationale behind these conferences is to improve the management of urban water systems through the development of computerbased methods. Issues such as economic globalisation, climate changes and water shortages call for a new approach to water systems management, which addresses the relevant technical, social and economic aspects. This collection represents the views of academic and industrial experts from a number of countries, who provide technical solutions to current water management problems and present a vision for addressing the global questions. The themes underlying many of the contributions include energy and material savings, water savings and the integration of different aspects of water management. The papers are grouped into three themes covering water distribution systems, sustainable urban water management and modelling of wastewater treatmentplants.The water distribution topics cover asset and information management, planning, monitoring and control, hydraulic modelling of steady state and transients, water quality and treatment, demand and leakage management, optimisation, design and decision support systems, as well as reliability and security of water distribution systems. The sustainable urban water management topics include urban drainage systems, water reuse, social aspects of water management and also selected facets of water resources and irrigation. Computer control of wastewater treatment plants has been seen as less advanced than that of clean water systems. To address this imbalance, this book presents a number of modelling techniques developed specifically for these plants.Water Management Challenges in Global Change will prove to be invaluable to water and environmental engineering researchers and academics; managers, engineers and planners; and postgraduate students.
Water Management Innovations in England (Routledge Revivals)
by Lyle E. CraineAs pressures on water resources have increased, problems of water quality have claimed high priority in national concern and governmental policy. In this book, first published in 1969, Lyle E. Craine describes how Great Britain enacted new governmental procedures for studying, planning, and executing water management programmes. Although the physical and social characteristics of the United States’ water resources problems differ from those of England, this analysis of the British institutional arrangements for water management suggests constructive insights for managing water resources within the individual states. This title is a valuable resource for students interested in environment and sustainability issues, national water resources problems, and government policy making.
Water Management and Public Participation
by Alka UpadhyayIntegrated Water Resources Management (IWRM) is an approach that promotes the coordinated development and management of water, land and related resources, in order to maximize economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems. Without public interest and participation, successful implementation of IWRM plans for river basin cannot be possible. Further to this, management at the watershed level to assure water supplies to support livelihood (i.e. domestic water, irrigation, industries, etc.) and sustainable groundwater development requires water augmentation through water conservation structures, and pollution control will also play a vital role. In India, because of limited period of rainfall during Monsoon (i.e. three to four months), water conservation and rainwater harvesting have been practiced since ancient days in order to meet water demands throughout the year. These structures are generally constructed and operated through the public participation. Keeping in view of the importance of public partnership, the role of public partnership in context of water-related awareness and practices has been investigated in different parts of the Yamuna River basin. The investigation evaluates the impact of various water conservation devices on livelihood; compares the performance of recently developed water conservation structures with ancient structures; examines spatial variation of water-related problems in the basin; and proposes an institutional setup for effective governance.
Water Management and Violent Conflict in East Africa: Scarcity and Security in Kenya and Uganda (Earthscan Studies in Water Resource Management)
by Julia Renner-MugonoThis book examines the complex interrelationships between water availability, governance and violent and non-violent conflicts, drawing on in-depth case studies of Lake Naivasha in Kenya and Lake Wamala in Uganda. When international economic endeavours like flower farming, oil exploration and extensive rice growing are coupled with a government's prioritization of economic development, not only does this lead to the commercialization of water resources but it also creates conflicts between national, regional and local stakeholders. Often overlooked in existing literature, such is the case even in water abundant areas like Lake Naivasha and Lake Wamala. Presenting a comparative study, the book provides a unique perspective on multifunctional water use and illustrates how politically and economically motivated water use increases violent tensions over access to and the use of freshwater resources. The coverage stretches from international and national agencies to NGOs, economic stakeholders and local actors. The book evaluates the resilience and vulnerability of local actors' ability to access water and examines the nexus between the need to access water and the ability to influence access to water, taking into consideration both countries’ economic development agendas. The book concludes by discussing strategies for reducing water-induced conflicts that can be applied to not only these cases but water conflicts across the globe. This book will be of great interest to scholars and professionals of water resource management and governance, African development, conflict resolution and sustainable development.
Water Management and Water Governance: Hydrological Modeling (Water Science and Technology Library #96)
by V. P. Singh Ashish Pandey S. K. Mishra M. L. Kansal R. D. SinghThis book focusses on hydrological modeling, water management, and water governance. It covers the applications of remote sensing and GIS tools and techniques for land use and land cover classifications, estimation of precipitation, evaluation of morphological changes, and monitoring of soil moisture variability. Moreover, remote sensing and GIS techniques have been applied for crop mapping to assess cropping patterns, computation of reference crop evapotranspiration, and crop coefficient. Hydrological modeling studies have been carried out to address various issues in the water sector. MODFLOW model was successfully applied for groundwater modeling and groundwater recharge estimation. Runoff modeling has been carried out to simulate the snowmelt runoff together with the rainfall and sub-surface flow contributions for snow-fed basins. A study has been included, which predicts the impact of the land use and land cover on stream flow. Various problems in the water sector have been addressed employing hydrological models such as SWAT, ArcSWAT, and VIC. An experimental study has been presented wherein the laboratory performance of rainfall simulator has been evaluated. Hydrological modeling studies involving modifications in the curve number methodology for simulation of floods and sediment load have also been presented. This book is useful for academicians, water practitioners, scientists, water managers, environmentalists, and administrators, NGOs, researchers, and students who are involved in water management with the focus on hydrological modeling, water management, and water governance.
Water Management in China’s Power Sector (Earthscan Studies in Water Resource Management)
by Jim W. Hall Xiawei LiaoThis book examines water resource management in China’s electric power sector and the implications for energy provision in the face of an emerging national water crisis and global climate change. Over 75% of China’s current electricity comes from coal. Coal-fired power plants are reliant on water, with plants using significant volumes of water every year, yet water resources are unevenly distributed. In the face of serious environmental concerns and increasing electricity demand, this book examines the environmental impacts that coal power plants have on water resources and the impact water availability has on the electricity sector in a country with a significant number of water-scarce provinces and a large number of power plants located on inland waterways. It discusses the water impacts and constraints for transforming the electric power sector away from coal to renewable energy sources, such as hydropower and concentrated solar power. The book adopts a mix-method approach, combining a plant-level quantitative analysis on water impacts and dependencies in China’s electricity sector and a qualitative analysis of relevant institutions in both sectors. By reviewing policy and institution cases in China’s water and electricity sectors, the book provides important recommendations calling for coordinated institutions to shift away from the current paradigm where water and electricity are governed independently. Enriching the water-energy nexus literature, this book will be of great interest to students and scholars working on water resource management, energy industries and Chinese environmental policy, as well as policymakers and practitioners in those fields.

Water Management, Food Security and Sustainable Agriculture in Developing Economies (Earthscan Studies in Water Resource Management)
by M. Dinesh Kumar Nitin Bassi M. V. K. SivamohanThis book addresses strategies for food security and sustainable agriculture in developing economies. The book focuses primarily on India, a fast developing economy, whose natural resource base comprising land and water supporting agricultural production is not only under enormous stress, but also complex and not amenable to a uniform strategy. It critically reviews issues which continue to dominate the debate on water management for agricultural and food production. The book examines the validity of the claim that large water resources projects cause serious social and environmental damages using global and national datasets. The authors examine claims that the future of Indian agriculture is in rain-fed farming supported by small water harvesting. They question whether water-abundant eastern India could become the granary of India, through a groundwater revolution with the right policy inputs. In the process, they look at the less researched aspect of the food security challenge, which is land scarcity in eastern India. The book analyzes the physical, economic and social impacts of large-scale adoption of micro irrigation systems, using a farming system approach for north Gujarat. Through an economic valuation of the multiple use benefits from tank systems in western Orissa, it shows how value of water from large public irrigation systems could be enhanced. The book also looks at the reasons for the limited success in bringing about the much needed institutional reforms in canal irrigation for securing higher productivity and equity using case studies of Gujarat, Madhya Pradesh and Maharashtra. Finally it addresses how other countries in the developing world, particularly Sub-Saharan Africa could learn from Indian experience.

Water Planning in Britain (Routledge Library Editions: Water Resources)
by Dennis J. Parker Edmund C. Penning-RowsellOriginally published in 1980, this book provides a penetrating and scholarly analysis of the planning of water resources, based on 10 years’ of research into one of Britain’s most vital industries. At the time of original publication Britain had a plentiful natural supply of water, but accessible clean water was scarce; droughts were not uncommon, floods often caused considerable damage; water bills were rising dramatically and consumption increasing inexorably. All of which applies as much to water resources in the UK today. Water planners must strike a delicate balance between many conflicting social, environmental, political and financial demands. Britain’s water authorities are large and autonomous organisations subject to constant change and controversy. Water policies affect not only water but also land-use planning, recreation planning, environmental quality, food production and the maintenance of public health. The book explains common threads and issues in the planning of 4 main water functions: water supply, effluent disposal and pollution control, water recreation and amenity and land drainage and flood alleviation. 11 original British case studies have been selected to illustrate the issues involved. The final chapter presents a critical and controversial evaluation of water policy and planning institutions in Britain, highlighted by some international comparisons.
Water Policies in MENA Countries (Global Issues in Water Policy #23)
by Slim ZekriThe book provides an overview on national policies and regulations related to water resource management in the Middle East and North African countries (MENA), where water scarcity problems are critical. The physical/natural constraints, socio-economic and political circumstances make the MENA region a sort of ‘laboratory’ for natural resource management and particularly water management. The book provides a good comparison on how neighboring countries with quite similar natural constraints and cultures are addressing water problems in different ways. It enlightens water resource specialists on successful experiences around the region and show cases the reforms undertaken in the water sector to meet the challenges posed by urbanization, food security, water pollution and climate change. The book constitutes nine chapters, seven of them with content from the main MENA countries. It starts with an introductory chapter that provides background information on the region’s water resources with descriptive statistics and historical developments of the water sector. It ends with a chapter that summarizes the policy implications and main conclusions on the way forward for sustainable management of water in MENA countries.
Water Policy in Chile (Global Issues in Water Policy #21)
by Guillermo DonosoThis book offers a detailed examination of the main sources of Chile’s water, its principle consumers, the gap between supply and demand, hydrological droughts, and future projected impacts of climate change. It describes, analyzes and evaluates the performance of water policies, laws and institutions, identifies the main challenges that Chile needs to face and derives lessons learnt from Chile’s reform experience.Expert contributors discuss such topics as Chile’s water policy, and the reasoning which explains its policy reform. The book presents and evaluates the performance of the legal and institutional framework of water resources. It also describes efforts to meet actual demands for water by augmenting supplies with groundwater management, waste water re-use and desalination and improve the state of water ecosystems. The last chapter presents the editor’s assessment and conclusions. The case of Chile is illustrative of a transition from command and control to market based management policies, where economic incentives play a significant role in water management.
Water Policy in Israel
by Nir BeckerThis book deals with water policy in Israel. It offers a detailed examination of the main sources of Israel's water, its principle consumers, the gap between supply and demand, and the complex, contentious work of analyzing and devising the nation's water management and use policies. Water Policy in Israel is arranged in five broad sections: The dynamics of moving from one policy era to another; Supply management; Demand management; The importance of the Sea of Galilee and the Dead Sea; and Regional and global issues including water conflict and cooperation and climate change.
Water Policy in Mexico: Economic, Institutional and Environmental Considerations (Global Issues in Water Policy #20)
by Hilda R. Guerrero García RojasMexico is currently facing severe problems with water availability, wastage and contamination. The most contaminated and over-exploited water resources are concentrated in the most populated areas of the country, where water is scarcer and its quality makes it unsuitable for a variety of uses, including human consumption. At the same time it is indisputable that water quality is a determining factor in public health and ecosystems. The significant growth in population and industry results in a high demand for water, along with contaminating discharges, few of which are treated – and the impact upon the ecosystems is evident. This book addresses all these topics in a single volume, taking into account the challenges presented by the economic, institutional and environmental considerations in Mexico’s water policy framework.
Water Policy in Pakistan: Issues and Options (Global Issues in Water Policy #30)
by Mahmood AhmadThe water policy issues are well- documented in a large set of reports and studies, completed over time showing that the policy prescription and its implementation has been weak in the past as this book reveals. The key reforms initiated were lost due to a lack of government’s will and commitment and more so by pervasive political economy of water. Given this background, each chapter in the book follows a balanced approach in seeking and evaluating alternate solutions to water management issues, especially improvements in water governance and tackling new challenges emerging from the climate change in the short and long term. This approach underpins the importance of moving from the culture of piloting projects to actual implementation on an impact-oriented scale. The book would also highlight that most of the water solutions lie outside the water sector such as agriculture, population, economy, etc. Post COVID-19 policies are exploring new food-health nexus that calls for nature based solutions for our future agriculture growth. The book would show case pioneer work underway in Pakistan on how new policy discourse can reduce water use in agriculture without investing in expensive water technology and infrastructure, thus saving enough water for other competing purposes.
Water Policy in Spain
by Alberto Garrido M. Ramón LlamasThough the modern Spanish State was formed in the mid Fifteenth Century, historical records show that water works, statues, and the utilization of water dates back to centuries BC. As a semi-arid country, the effort to control, store and assure water supplies to cities and fields is present in numerous historical and political landmarks.Water polic
Water Politics and the On-Paper Hydropower Boom: Power, Corruption, and Sustainability in Emerging Economies (Earthscan Studies in Water Resource Management)
by Özge Can DogmusThis book examines how the on-paper hydropower boom impacts the safe and fair access to water and energy in emerging economies.The global hydropower boom is largely made up of small hydropower plants located in emerging economies, but a lack of funding, over-ambitious planning, and corruption have halted the production of these projects. Describing this state as the ‘on-paper’ hydropower boom, this book shifts attention to the hydrosocial problems arising from hydropower projects that remain on paper. It examines how these proposed but unbuilt projects can lead to disruptions in the control and governance of water resources and increase the international dependence of emerging countries due to deep problems in their sustainable development planning and how all this can affect both ecosystems and the communities that depend on them. In doing so, it critically examines the dominant discourses on energy security and sustainable development, emphasises the extent to which the effects of global imperialism are at play, and examines the effects of international power relations in the hydrosocial context and their implications for perpetuating international relations of dependency. Further, this book provides a unique perspective on the global hydropower boom by highlighting that although the global hydropower boom largely remains on paper, it can still have a significant impact on human–water systems. Contributing to the debate on hydrosocial relationships, each chapter offers an insightful examination of the social, cultural, and political interactions that humans have with water and uses these insights to provide a nuanced understanding of the challenges and issues associated with on-paper plans.This book will be of great interest to students and scholars of water politics, water governance, political ecology, corruption and environmental economics, as well as sustainable development policymakers.
