Book SynopsisPresents recent challenges related to new forms of pollution from industries and discusses adequate state-of-the-art technologies capable to remediate such forms of pollution. Over the past few decades the boom in the industrial sector has contributed to the release in the environment of pollutants that have no regulatory status and which may have significant impact on the health of humans and animals. These pollutants also referred to as emerging pollutants, are mostly aromatic compounds which derive from excretion of pharmaceutical, industrial effluents and municipal discharge. It is recurrent these days to find water treatment plants which no longer produce water that fits the purpose of domestic consumption based on newly established guidelines. This situation has prompted water authorities and researchers to develop tools for proper prediction and control of the dispersion of pollutants in the environment to ensure that appropriate measures are taken to prevent thTable of ContentsPreface xv Part 1: Occurrence of Emerging Pollutants in Water and Possible Risks 1 1 Geochemical Prediction of Metal Dispersion in Surface and Groundwater Systems 3Martin Mkandawire 2 From Priority Contaminants to Emerged Threat: Risk and Occurrence-Based Analysis for Better Water Management Strategies in Present and Future 41Hussein N.

Book SynopsisDyes, pigments and metals are extensively used in food, paper, carpet, rubber, plastics, cosmetics, and textile industries, in order to color and finish products. As a result, they generate a considerable amount of coloured wastewater rich in organic, inorganic, and mineral substances which are continuously polluting the water bodies and affecting human and aquatic life. Besides these industries, urban and agricultural activities also generate effluents high in biochemical oxygen demand (BOD) and chemical oxygen demand (COD). In recent years, considerable research work has been done in this area and is underway to eliminate heavy metals particularly mercury (Hg), chromium (Cr), lead (Pb), selenium and cadmium (Cd) and synthetic dyes from polluted waters which have high toxicity and carcinogenicity. Currently a number of methods are in operation to decontaminate the polluted waters. Among several purification technologies, use of nanoparticles/composites have gained much attention asTable of ContentsPreface xiii 1 Environmental Toxicity of Nanoparticles 1Mohammad Shahadat, Momina, Yasmin, Suzylawati Ismail, S.

Book SynopsisA primary responsibility of a water quality engineer is to supply potable and palatable drinking water to a community. Water Treatment covers the gamut of operations that are required to convert a raw water source—whether surface water or groundwater—to a quality that conforms to all federal, state, and local environmental standards for drinking water. This book includes basic chemistry principles that are indispensable to a fundamental understanding of water treatment operations. The goal is to enable the reader to quickly find all the information—without any need for multiple sources—required to clearly understand concepts that are integral to water treatment. Numerous solved examples throughout the book facilitate a step-by-step approach to any water treatment process.

Book SynopsisThirty years ago, Low Life appeared to universal acclaim and secured Luc Sante's status as the author of that cult classic of alternative New York City history. Now, he returns with another sidelong NYC history-here, the making of the upstate reservoir system that reliably supplies one of the world's greatest metropolises with its fresh water, and without which the city would almost certainly have faded into insignificance. This meticulously detailed book is both an immersive history and a meditation on the significance of these willed-from-nature bodies of water to the city-past, present, and future.

Book SynopsisGlobally, poor hygiene and sanitation contribute to more than 1,000 daily deaths from diarrhoeal diseases among children under the age of 5, while two thirds of urban wastewaters are discharged without treatment into lakes, rivers and coastal waters. Across Europe the percentage of the population connected to wastewater treatment plants varies from 14% to >99% with many reliant on unsuitable decentralised sanitation systems or no wastewater treatment at all. With less than a decade left to achieve the 2030 sanitation targets as set out in the Sustainable Development Goals, there is an urgent need to develop new treatment solutions that can be rapidly deployed to meet the needs of growing urban and peri-urban populations, together with under-served rural communities. This book discusses decentralised wastewater treatment and the role of nature-based solutions within the context of the twenty-partner international INNOQUA project. INNOQUA set out to develop and demonstrate a suite of modular, low cost, decentralised solutions that use the combined capabilities of earthworms, bacteria, Cladocera and micro-algae to deliver nature-based primary, secondary and tertiary treatment – followed by UV disinfection. Design and operation principles are outlined, together with performance data and practical feedback from pilot and demonstration facilities situated in eleven countries from Ecuador to Scotland and India. Barriers and drivers towards more widespread uptake of these technologies are also examined, alongside an exploration of existing markets for nature-based sanitation in the Global South.Table of Contents Foreword Chapter 1. Introduction to the INNOQUA project Chapter 2. Drivers and Barriers towards a Sustainability Transition in the Wastewater Sector – A NEXUS perspective with nature-based solutions Chapter 3.

Book SynopsisThe focus of municipalities has been on the supply of sufficient water quantities to the public with less attention paid to water quality. The deteriorating quality of raw water sources necessitates increased attention to water quality, with professional scientists playing a central role at municipalities and water boards together with professional engineers.With many stringent regulations on the quality of drinking water and recreational water bodies, the young municipal chemist needs a handy manual to assist in the often neglected and complicated field of municipal water management. Grounded in solid science, Introduction to Municipal Water Quality Management not only links theory and regulations in practice but also offers simple numerical examples to better understand the rules and encourage a quantitative application to everyday problems. Developed from a series of lectures between 2015 and 2019, Introduction to Municipal Water Quality Management will give young professionals the confidence to analyse their results and apply their knowledge in a numerical fashion.

Book SynopsisWater is critical to all human activities, but access to this crucial resource is increasingly limited by competition and the effects of climate change. In agriculture, water management is key to ensuring good and sustained crop yields, maintaining soil health, and safeguarding the long-term viability of the land. Water management is especially challenging on smallholder farms in resource-poor areas, which tend to be primarily rainfed and thus highly dependent on unreliable rainfall patterns. Sustainable practices can help farmers promote the development of soils, plants and field surfaces to allow maximum retention of water between rains, and encourage the efficient use of each drop of water applied as irrigation. Using simplified concepts and easy-to-understand language, this book: - outlines the theoretical underpinnings of sustainable water management in agriculture, -introduces a range of beneficial practices, including the enhancement of soil water retention, water loss reduction, rainwater harvesting, conservation agriculture, and small-scale irrigation -provides schematic diagrams, and resources for further reading to help readers put theory into practice Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.Table of Contents1: Theoretical Foundations of Water Management in Agriculture 1: Key Concepts 2: Goals of Agricultural Water Management 3: Soil and Water 4: Plants and Water 5: Climate Outlook 2: Improving Water Productivity in Rainfed Agriculture 6: Soil-focused Strategies: Reducing Water Loss 7: Rainwater Harvesting 8: Crop-focused Strategies: Using Available Water Wisely 9: Conservation Agriculture 3: Irrigation 10: Irrigation 11: Irrigation Scheduling 12: Water Sources for Agriculture -: Summary of Key Points

Using simplified concepts and easy-to-understand language, this book: - outlines the theoretical underpinnings of sustainable water management in agriculture, -introduces a range of beneficial practices, including the enhancement of soil water retention, water loss reduction, rainwater harvesting, conservation agriculture, and small-scale irrigation -provides schematic diagrams, and resources for further reading to help readers put theory into practice Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.Table of Contents1: Theoretical Foundations of Water Management in Agriculture 1: Key Concepts 2: Goals of Agricultural Water Management 3: Soil and Water 4: Plants and Water 5: Climate Outlook 2: Improving Water Productivity in Rainfed Agriculture 6: Soil-focused Strategies: Reducing Water Loss 7: Rainwater Harvesting 8: Crop-focused Strategies: Using Available Water Wisely 9: Conservation Agriculture 3: Irrigation 10: Irrigation 11: Irrigation Scheduling 12: Water Sources for Agriculture -: Summary of Key Points

Book SynopsisAgriculture in the Murray-Darling Basin of Australia represents a controversial 'policy experiment' comprising large capital investments, innovation and enterprise across a hundred-year period. This book, which contains contributions from some of Australia's foremost economic, social science and public policy researchers and writers, examines the evolution of public policy frameworks that transformed water management from initial exploitation for irrigation as a dominant single use to a dynamic multiple use resource system. Water Policy Reform provides both analytical insights and examples of successes and failures in developing water policy in a complex and politically-contested environment. As such, this work attempts to develop a comprehensive management plan for the Basin and provides novel and invaluable lessons for an increasingly global problem. This well-researched study will interest both economists and those with public policy interest in academia and the public sector, including development agencies concerned with sustainable water resource management.

Morrison, N. Nguyen, D. Pannell, J. Quiggin, H. Ross, A. Ryan, P. Schrobback, S. Tapsuwan, A. Watson, M. Young, Z. ZarezadehTrade ReviewManaging the water of the Murray Darling Basin has emerged as one of the greatest challenges for Australia's scientists, social scientists and policy makers. This book brings together some of Australia's leading economists and social scientists to discuss ideas and solutions for a national problem that is both intriguing and exasperating. Readers will enjoy the candid discussion of both the distant and recent history of this issue, plus the innovative solutions. From a philosophical perspective the reader may wish to muse on the relative merits of different degrees of free market and private property approaches vs top-down control as they pertain to the past, present and future of Australia's largest river basin. --Hugh Possingham, University of Queensland, AustraliaThis book is a must read for anyone interested in how to ensure sustainability while effectively addressing social and economic issues. The contributors are all well recognised in their areas of expertise and their chapters are highly informative. The book's focus is on policy reform in the Murray Darling Basin. It offers a ''window to the future'' and important insights for other parts of the world that also face the dilemma of the overextraction of water and what to do about it. I highly recommend it. --Quentin Grafton, The Australian National University[T]he book is a major addition to the literature on water policy and river basin management, and should be widely circulated, read and discussed. --Sailen Routray, Current ScienceTable of ContentsContents: Foreword Introduction PART I: POLICY 1.

Book SynopsisToday, hundreds of millions of people drink contaminated water without knowing it. Yet water treatment technologies can effectively eliminate contamination and can supply urban and rural populations with safe drinking water in a secure way. For almost two centuries, the huge number of treatments available to guarantee water quality has grown alongside technological progress, the strengthening of industry norms and the reinforcement of consumer expectations. New treatment methods have been developed according to the advancement of knowledge and new sanitary regulations. This five-volume book sets out to clearly present the variety of treatments available along with their performance, limitations and conditions of use as well as ways to combine them to produce safe drinking water, which is a basic need essential to everyday life. The author shares his expertise acquired at Veolia, a company that is a world leader in water services and sanitation, desalination of sea water and the recycling of wastewater. Founded in France in 1853 to bring safe water to populations and to protect them from waterborne epidemics which ravaged cities, its history is intertwined with that of water treatment.Table of ContentsChapter 20 Calco-carbonic Equilibrium, Correction of Aggressivity and Remineralization 1 20.1 Characteristics of water leading to calco-carbonic equilibrium 2 20.1.1 Chemical equilibria 2 20.1.2 Aggressive water 12 20.1.3 Scaling water 12 20.1.4 Corrosive water 12 20.2 The equilibrium reactions of water’s constituents 15 20.2.1 Equilibrium pH 16 20.2.2 Langelier equation 20 20.3 Hallopeau–Dubin diagram 25 20.4 Indicative criteria to determine the aggressivity or corrosivity of water 29 20.4.1 Indicators of aggressivity: concrete pipelines 29 20.4.2 Corrosivity indicators 32 20.5 The calco-carbonic equilibrium of water 36 20.5.1 Water quality and regulations 38 20.5.2 The correction of aggressivity 38 20.5.3 Aggressivity correction treatments 39 20.6 Remineralization treatments 60 20.6.1 Graphic method 61 20.6.2 Processes for implementing remineralization: chemical reactions in tanks 62 20.7 Characteristics of the various reagents used 85 20.7.1 Lime 85 20.7.2 “Micronized” lime 86 20.7.3 Caustic soda 86 20.7.4 Caustic soda at 50% 87 20.7.5 Caustic soda flakes or grains 87 20.7.6 Sodium carbonate 88 20.7.7 Sodium bicarbonate 89 20.7.8 Calcium carbonate 89 20.7.9 Acticalmag limestone 90 20.7.10 Magno 90 20.7.11 Calcium sulfate 91 20.7.12 Calcium chloride 92 20.7.13 Carbon dioxide 92 20.7.14 Sulfuric acid (90–98%) 93 20.7.15 Hydrochloric acid 94 20.8 References 96 Chapter 21 Disinfection 99 21.1 Microorganisms present in the water 99 21.1.1 Bacteria 99 21.1.2 Indicator microorganisms or test germs 102 21.1.3 Viruses 104 21.1.4 Parasites 105 21.1.5 Micro-algae 107 21.2 Quality of potable water 108 21.2.1 French regulations 108 21.3 General rules of chemical disinfection 110 21.3.1 Disinfection mechanisms 110 21.3.2 The mode of action of chemical disinfectants 111 21.3.3 Inactivation kinetics 112 21.3.4 The notion of Ct 113 21.4 Factors affecting the efficiency of chemical disinfection 117 21.4.1 Contact time 117 21.4.2 Turbidity 118 21.4.3 Presence of oxidizable matter 118 21.4.4 pH 119 21.4.5 Injection mode and injection point 119 21.4.6 Design of the contact tank 119 21.5 Qualities of a good disinfectant 120 21.6 Chlorine disinfection 121 21.6.1 Gaseous chlorine 122 21.6.2 Hypochlorite 124 21.6.3 Chlorine application points 128 21.6.4 Oxidant demand 132 21.6.5 The implementation of chlorination 137 21.6.6 Disinfection performances with chlorine 146 21.6.7 Synthesis of chlorine reactions 148 21.7 Calcium hypochlorite 149 21.8 Chlorine dioxide disinfection 150 21.8.1 Chlorine dioxide preparation 151 21.8.2 Chlorine dioxide performances 155 21.8.3 Dechlorination 157 21.8.4 The advantages of dioxide over chlorine 159 21.8.5 The special case of the use of chlorine dioxide at a station equipped with ozone 160 21.8.6 Advantages and drawbacks of using chlorine dioxide 160 21.9 Chloramination 161 21.9.1 Principle 161 21.9.2 Implementation 163 21.9.3 Performances of monochloramine 164 21.9.4 Dechloramination 165 21.9.5 Advantages and drawbacks of chloramination 166 21.10 Proportion of chlorine in chlorine disinfectants 167 21.11 Disinfection with ozone 168 21.11.1 General remarks on ozone 168 21.11.2 Ozone production 170 21.11.3 Ozone demand 172 21.11.4 The implementation of ozonation 174 21.11.5 Performances of ozone disinfection 181 21.11.6 De-ozonation 183 21.12 Criteria for choosing a chemical disinfection technique 184 21.12.1 Practical implementation of chemical disinfection 184 21.12.2 Comparative efficiency of the main techniques 185 21.13 Another chemical disinfectant used: bromine (Br 2) 187 21.14 Disinfection by ultraviolet radiation 187 21.14.1 General remarks on UV radiation 187 21.14.2 Inactivation mechanisms 189 21.14.3 Lethal dose and inactivation kinetics 190 21.14.4 Implementation 194 21.14.5 UV disinfection design parameters 199 21.14.6 Factors affecting the efficiency of a UV treatment 200 21.14.7 UV radiation performances 204 21.14.8 Photoreactivation 208 21.14.9 Advantages and drawbacks of UV disinfection 209 21.14.10 Conclusions on UV disinfection 209 21.15.

Book SynopsisProviding an extensive comparative and international study of water innovations and the issues that arise in their implementation, David Lewis Feldman analyses the technical, economic, health and environmental impacts of water innovations and their policy implications.Discussing desalination, rainwater harvesting, wastewater reuse, and demand-side innovations as well as emerging cyber-infrastructure issues, The Governance of Water Innovations analyses the historical and contemporary challenges involved in water innovations. With a global reach, exploring water innovations across The Americas, Asia, Australia and Europe, chapters consider potential areas of contention involving land use, aesthetics, recreational impacts, user costs, and environmental quality. Illuminating the importance of these challenges and determining the most effective and equitable ways of meeting them, Feldman advises how innovations should be deployed, governed and implemented democratically in ways that harbour public acceptance, trust, and engagement for a water resilient future.A comprehensive study of the governance of water innovations, this book will prove invaluable to students and scholars of public policy, environmental and water studies and geopolitics. With its pioneering analysis of adaptive governance, it will also prove an essential reference guide to practitioners, professionals and policymakers working in water governance and management, including water agency officials and water resource legislators.Trade Review‘David Feldman has done it again. With his latest book, The Governance of Water Innovations, he reminds us of the limits of technology in governing water. In a time when we are searching for solutions to solve our water woes, Feldman appropriately calls for a more democratic, public engaged process.’ -- Andrea K.

Book SynopsisThe authors of this in-depth study describe the theory and techniques that can be applied to the specific case of valuing potable water provided by groundwater supplies. The theory and techniques can be extended to valuing drinking water provided by surface water supplies, and also to valuing alternative levels of water quality. The theory and case studies discussed in the book suggest that important determinants of the economic value of water quality include: the probability of contamination measured objectively and subjectively, information on actual levels of contamination in household water supplies, socioeconomic characteristics of households, and the extent to which the values of water quality people hold include non-use components. The case study results also suggest that empirical valuation results are sensitive to study design effects such as the particular statistical technique used to estimate mean or median values. These results suggest that estimating water quality values using benefits transfer techniques is problematic, but perhaps feasible with improved data and valuation models.Government agencies, private consulting firms and NGOs involved in water quality policy as well as academic researchers, professors and students will find this volume of theory, application and technique an invaluable reference.Trade Review'. . . the book is of immediate policy significance.

Book SynopsisThe Economics of Industrial Water Use presents an authoritative collection of the most important articles to have applied economic models and measurement techniques to the topic of industrial water use over the last thirty years. It includes an original introductory chapter which summarizes and critically assesses the literature on this important subject.These papers employ a range of modelling approaches including econometric estimation, linear programming, input-output models, non-market valuation and integrated river basin planning models. They also provide empirical evidence of the significant role played by economic forces in determining industrial water intake, discharge and recirculation.This comprehensive volume will be an indispensable reference source for those with an interest in water's role in industrial applications.Trade Review'As water becomes scarcer and as the industrial sector expands in many countries, the competition over the resource among sectors is more difficult. Industrial water consumption has doubled over the past decade in several countries, and is expected to rise more as industry expands. Economic instruments play an important role in efficient allocation of scarce water resources. This book demonstrates how knowledge of features of industrial water use coupled with economic instruments may enhance efficient water management. Reading this book is a fascinating voyage through the existing economic literature that was published in the last 30 years. The book combines the work of the most authoritative scholars in this field. All together it provides the reader with the necessary technical and economic background that can be used to address various industrial water use issues.' -- Ariel Dinar, The World BankTable of ContentsContents: Acknowledgements Introduction Steven Renzetti PART I EARLY PAPERS 1.

Book SynopsisThis important collection reprints the most significant papers and case studies on the prevention and resolution of conflict over water resources. It focuses in particular on the human dynamics that are involved when conflicts over water resources impact on different interest groups, economic sectors and legal or political boundaries. It addresses key issues which arise at both the local and the international level, including amongst others: How do people interact in these situations of conflict? What methods do they use to find a compromise? What institutions do they create - either jointly or unilaterally - to help overcome problems in the future?This interdisciplinary collection will be essential reading for professional water practitioners throughout the world, including engineers, economists, geographers, geologists, and political scientists concerned with water disputes and conflict resolution. It will make a significant contribution to the study of water as an essential theme in the increasingly important topic of environmental security.Trade Review'. . . this volume . . . is certainly a valuable addition to university and research libraries.' -- Claudia Ringler, Quarterly Journal of International Agriculture'Overall, I believe that Dr Wolf has edited a valuable reference for researchers and practitioners who are interested in responsibly managing and equitably resolving conflicts over water and the environment. This reference furnishes informative background information for both graduate and undergraduate courses in water management and provides guidance for future research on conflict resolution in water resources . . . Dr. Wolf's well-organized book on water conflict brings together under one cover a wealth of valuable information from a wide variety of sources that would be difficult to obtain otherwise.' -- Keith W.

Book SynopsisThe lack of sufficient access to clean water is a common problem faced by communities, efforts to alleviate poverty and gender inequality and improve economic growth in developing countries. While reforms have been implemented to manage water resources, these have taken little notice of how people use and manage their water and have had limited effect at the ground level. On the other hand, regulations developed within communities are livelihood-oriented and provide incentives for collective action but they can also be hierarchal, enforcing power and gender inequalities. This book shows how bringing together the strengths of community-based laws rooted in user participation and the formalized legal systems of the public sector, water management regimes will be more able to reach their goals.Table of Contents1: Community-Based Water Law and Water Resources Management Reform in Developing Countries: Rationale, Contents and Key Messages 2: Understanding Legal Pluralism in Water and Land Rights: Lessons from Africa and Asia 3: Community Priorities for Water Rights: Some Conjectures on Assumptions, Principles and Programmes 4: Dispossession at the Interface of Community-Based Water Law and Permit Systems 5: Issues in Reforming Informal Water Economies of Low-Income Countries: Examples from India and Elsewhere 6: Legal Pluralism and the Politics of Inclusion, Recognition and Contestation of Local Water Rights in the Andes 7: Water Rights and Rules, and Management in Spate Irrigation Systems in Eritrea, Yemen and Pakistan 8: Local Institutions for Wetland Management in Ethiopia: Sustainability and State Intervention 9: Indigenous Systems of Conflict Resolution in Oromia, Ethiopia 10: Kenya's New Water Law: An Analysis of the Implications of Kenya's Water Act, 2002 for the Rural Poor 11: Coping with History and Hydrology: How Kenya's Settlement and Land Tenure Patterns Shape Contemporary Water Rights and Gender Relations in Water 12: Irrigation Management and Poverty Dynamics: Case Study of the Nyando Basin in Western Kenya 13: If Government Failed, How Are We to Succeed?

Book SynopsisWater issues in the American West share many similarities with those seen elsewhere in the world as population growth exacerbates longstanding problems of inappropriate water use and management. The contributors to this timely volume examine the universal challenge of sustainable water management to improve the use of water resources already developed and find ways to moderate our growing collective thirst.The volume begins with an exploration of the opportunities, arguments, and mechanisms for transferring lessons between the American West and foreign nations. Succeeding chapters cover individual issues such as: water allocation and the relationship between market mechanisms and government-based approaches, the challenge of environmental protection, the protection of cultural values with a focus on indigenous water rights, the significance of international and interstate rivers in promoting regional conflict and cooperation, and the role of water management in sustainable development. A comprehensive look at one of our most pressing issues, In Search of Sustainable Water Management will be of great interest to scholars and practitioners in the areas of water management, law, policy studies, economics, planning and public administration.Trade Review'This edited volume adeptly analyzes some of the most salient challenges that face water managers and policy makers: balancing private and public sector roles in water allocation, protecting environmental values and indigenous rights to water, avoiding transboundary water conflicts, and integrating the concept of sustainable development within water policies. . . the chapters in this book are comprehensive and well balanced. . . Kenney and his colleagues have put forth an important contribution to western water policy scholarship. They offer concrete ideas for sustainable water management in the western US informed by international cases, while acknowledging the West's unique political and social context.' -- Tanya Heikkila, Journal of the American Water Resources Association'Collectively the papers provide concise, insightful coverage of critical water problems in the US and carefully integrate relevant lessons from international water management into these discussions.

Book SynopsisThis book asks under which conditions cooperation is in the interest of the riparian countries sharing international waters, and how institutions must be designed to realize potential gains of cooperation. The author, Ines Dombrowsky, develops a conceptual framework that draws upon different economic theories, including the theory of external effects, non-cooperative game theory and transaction costs economics. She distinguishes the different types of externality problems inherent in international water management and specifies the institutional prerequisites for cooperation. She argues that the respective problems differ with respect to the need to define property rights and to establish enforcement mechanisms. The book also explores the role of issue linkage and of international organizations to foster cooperation. The theoretic considerations are compared and contrasted with the findings of a global review of international water treaties and organizations.By taking hydrological and legal aspects into account, this book provides an interdisciplinary contribution at the interface of hydrology, law and economics. As such, it is addressed to scholars, practitioners and policy-makers, including economists, political scientists, international lawyers, natural scientists, and water resource managers.Trade Review'While I recommend this book as a whole, a couple of its chapters are especially fascinating. I found the review of international law to be comprehensive and well structured, and the chapter on the role of problem structure to be mind opening, especially for demonstration of strategic behavior in the field of international water. This book will benefit those interested in the conflict-cooperation discourse in the field of international water.' -- Ariel Dinar, Land Economics'. . . this book offers a good summary of the issues surrounding integrated water resource management as a tool for water resource management across national boundaries an some useful alternative views on the issues. It would provide a useful resource for scholars, practitioners and policy-makers including economists, political scientists, international lawyers, natural scientists, and water resource managers.' -- Adam Loch, Land Use Policy'This data collection offers a great opportunity for further research on international water management, and some suggestions in this respect are also made in the final chapter, where the main findings are summarized and policy implications and research opportunities are offered.' -- Marit Brochmann, Journal of Peace ResearchTable of ContentsContents: Preface 1.

Book SynopsisThis broad review of the development of US water resource policy analysis and practice offers perspectives from several disciplines: law, economics, engineering, ecology and political science. While the historical context provided goes back to the early 19th century, the book concentrates on the past 60 years and features a discussion of the difficulty that has generally been encountered in bringing the disciplines of economics and ecology into collaboration in the water resource context.The book explores the evolution of water related analytical capabilities and institutions and provides illustrations from case studies, concluding with recommendations for research, institutional change and action. Though designed to be a background textbook for interdisciplinary graduate seminars in water resources planning and management, it is accessible to interested lay readers and those who have policymaking or implementation responsibility but lack a technical background.The book will appeal to students and faculty in water policy, economics, and engineering, and in interdisciplinary programs organized around water resource problems and questions. Policy makers and general readers will also appreciate this non-technical introduction.Table of ContentsContents: Foreword Robert A. Pietrowsky Preface 1.

Book SynopsisInterest in solid and hazardous waste management is relatively recent, i.e., in the last three decades, and is driven by regulations in most countries. It began with industrial hazardous waste followed by municipal solid waste, and subsequently by many other categories of waste.This book presents numerous examples and case studies of innovative tools, treatment methods and applications in this growing area of research and development. It describes in detail laboratory methods of measuring the biodegradation of specific organic fractions, like floral waste, and also discusses the treatment of yard and food waste by anaerobic digestion and landfill leachate using constructed wetlands. Case studies are provided that show how remote sensing (RS) and GIS were used to develop an integrated solid waste management plan for a city and to evaluate the environmental impacts of stone quarrying activities.The book also features chapters discussing the implications of natural radioactivity in beach placers and their impact on groundwater and other parts of the environment, as well as the twelve principles of green chemistry and their application in the reuse and recycling of solid waste. Moreover, it includes examples of waste to energy, like refuse derived fuel and biofuel generation and an evaluation of their potential, and covers topics such as life cycle assessment as a tool for developing integrated solid waste management systems and an overview of municipal solid waste management rules, illustrating the importance of technological inputs in the development of regulatory frameworks.Written by leading practitioners and scholars in the field, the book enables readers to understand and apply these principles and practices in their endeavours.Table of Contents

Book SynopsisThe world is faced with a growing number of complex and interconnected challenges. Water is among the top 5 global risks in terms of impacts, which would be far reaching beyond socio-economic challenges, impacting livelihoods and wellbeing of the people.As freshwater resources and population densities are unevenly distributed across the world, some regions and countries are already water scarce. Water scarcity is expected to intensify in regions like the Middle East and North Africa (MENA), which has 6% of the global population, but only 1% of the world’s freshwater resources. Climate change adds to this complexity as it is leading to rainfall uncertainty and extended droughts periods, mostly in arid areas.Increasing water scarcity is now recognized as a major cause of conflict, social unrest and migration and at the same time water is increasingly considered as an instrument for international cooperation to achieve sustainable development. Tapping and assessing sustainably every available option in water-scarce areas is needed as pressure continues to build on limited water resources.The stark fact is that conventional water provisioning approaches relying on snowfall, rainfall and river runoff are not enough to meet growing freshwater demand in water-scarce areas. Water-scarce countries need a radical re-think of water resource planning and management that includes the creative exploitation of a growing set of viable but unconventional water resources for food production, livelihoods, ecosystems, climate change adaption, and sustainable development. Unconventional water resources are generated as a by-product of specialized processes; need suitable pre-use treatment; require pertinent on-farm management when used for irrigation; or result from a special technology to collect/access water.Table of ContentsSECTION 1 – Setting the scene Chapter 1: Introduction (Editors) Chapter 2: Unconventional water resources as a response to global water scarcity and contribution to food, ecosystems, and sustainable development (Editors) SECTION 2 – harvesting water from air and on the ground Chapter 3: Rain enhancement through cloud seeding (Ali Abshaev, Hail Suppression Research Center, Nalchik, Russia) Chapter 4: Fog water harvesting (Jamila Bargach, Dar Si Hmad Project, Sidi Ifni, Morocco) Chapter 5: Micro-catchment rainwater harvesting (Theib Oweis, International Center for Agricultural Research in Dry Areas, ICARDA, Jordan) SECTION 3 – tapping offshore and onshore deep groundwater Chapter 6: Offshore water (Mark Person, New Mexico Institute of Mining and Technology, USA) Chapter 7: Onshore deep groundwater (Mark Person, New Mexico Institute of Mining and Technology, USA) SECTION 4 – reusing used water Chapter 8: Municipal wastewater (Birguy Lamizana, United Nations Environment Programme, UNEP, Nairobi, Kenya) Chapter 9: Agricultural drainage water (J.D.

Book SynopsisThis book documents the various impacts of urbanization on hydrological systems and water resources. The first half of the book is focused on urbanization and surface waters, starting with the status of hydrological systems in the urban areas, i.e. the catchment characteristics and changes in rainfall dynamics. The most pronounced hydrological problems in cities are changes in runoff due to precipitation. Recently, rain events have been less frequent but more intense, sometimes leading to flash floods. Though the substantial increase in runoff causes floods in the urbanized area, it may be attributed to the reduction of infiltration due to construction of roads. This, in turn, results in groundwater decline and depletion. The second half of the book covers the impact of urbanization on groundwater, which starts with hindered or significantly reduced recharge taking place due to altered urban surfaces. The limited groundwater resources are over-exploited by the urban population, leading to water scarcity and depletion. Groundwater gets polluted due to solid waste dumping sites or by wastewaters discharged by industries. The book will be useful for researchers, educators, municipal/city authorities, government officials, and NGOs.Table of ContentsChapter1.

Book SynopsisThe problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each one devoted to one of the 17 SDGs. This volume is dedicated to SDG 14 “Conserve and sustainably use the oceans, seas and marine resources for sustainable development". Marine and coastal bio-resources, play an essential role in human well-being and social and economic development. This volume addresses this sustainability challenge providing the description of a range of terms, which allows a better understanding and fosters knowledge about it.Concretely, the defined targets are: Prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution Sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels Effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics Conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on the best available scientific information Prohibit certain forms of fisheries subsidies which contribute to overcapacity and overfishing, eliminate subsidies that contribute to illegal, unreported and unregulated fishing and refrain from introducing new such subsidies, recognizing that appropriate and effective special and differential treatment for developing and least developed countries should be an integral part of the World Trade Organization fisheries subsidies negotiation 16 Increase the economic benefits to small island developing states and least developed countries from the sustainable use of marine resources, including through sustainable management of fisheries, aquaculture and tourism Increase scientific knowledge, develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing states and least developed countries Provide access for small-scale artisanal fishers to marine resources and markets Enhance the conservation and sustainable use of oceans and their resources by implementing international law as reflected in the United Nations Convention on the Law of the Sea, which provides the legal framework for the conservation and sustainable use of oceans and their resources, as recalled in paragraph 158 of “The future we want” Editorial BoardUlisses M.
