Book Description
Water institutions establish the incentives, information, and compulsions that guide behaviour and influence economic outcomes. Water pricing policies that reflect the marginal cost of supply can bring about several positive benefits in the pipe-borne water sector including: 1) greater water use efficiency; 2) an increase in revenues that can be utilised to improve services; and 3) additional funds to enhance and expand the operation and maintenance of pipe-borne water supply systems. In order to design an appropriate pricing policy and bring about these positive changes, managers of pipe-borne water supply systems require an understanding of the determinants of water demand, supply and welfare changes. Further, the use of economic methodologies to estimate the effects of factors that influence pipe-borne water demand, supply and welfare in developing nations can assist water utility operators and policy makers to predict consumption responses to changes in water pricing. In turn, this provides important evidence for these decision makers to determine if price changes will result in higher revenues that can be used to fund critical infrastructure extension and maintenance. This is particularly important for developing nations where revenue constraints on water authorities can limit access to pipe-borne water supplies for large sections of the population. This book identifies under-pricing as the major problem faced by the Sri Lankan pipe-borne water sector. Recently, the water authority in Sri Lanka restructured its pricing strategy for pipe-borne water with the objectives of reducing water consumption and expanding the network. However, the success of the current pricing structure in achieving these objectives is uncertain. Therefore, to overcome the problems, this study examines the use of cost-reflective alternative pricing strategies for pipe-borne water distribution services. The book evaluates current and alternative pricing strategies for water against the criteria of efficiency and equity while maintaining the financial viability of the national water utility. In order to analyse the welfare impacts, understanding the demand for pipe-borne water by different user groups and the cost of pipe-borne water provision must be considered.

Book Description
Globalization has significantly redefined the nature of governance in the water sector. Non-state actors—multilateral and transnational donor agencies and corporations, non-government organizations, markets, and civil society at large—are assuming a bigger role in public policy-making for water resource management. New discourses on neoliberalism, integrated water resource management (IWRM), public–private partnerships, privatization, and gender equity have come to influence water governance. Drawing upon detailed case studies from India, Bangladesh, Nepal, Sri Lanka, and Bhutan, this volume shows the implications of these new global paradigms for water allocation and management practices, institutions and governance structures in South Asia. It suggests that, despite claims to the contrary, they have done little to further human well-being, reduce gender disparity, or improve accountability and transparency in the system. Steering away from blueprint approaches, it argues for a more nuanced and contextual understanding of water management challenges, based on local knowledge and initiatives. This book will be useful to those interested in political economy and water governance, natural resource management, environmental studies, development studies, and public administration, as well as to water professionals, policy-makers and civil society activists.

Book Description
This report is a view of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regard to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. A broad classification has been made based on climate and the traditional agricultural background of the local people, which links technology options to specific places--to agricultural regions and to countries.

Book Description
This book reviews the prevalence and variants of consumer subsidies found in the developing world and the effectiveness of these subsidies for the poor. It places consumer subsidies in a broader social protection framework and compares them with poverty-focused programmes in other sectors using a common metric. It concludes that the most common subsidy instruments perform poorly in comparison with most other transfer mechanisms. Alternative consumption and connection subsidy mechanisms show more promise, especially when combined with complementary non-price approaches to making utility services accessible and affordable to poor households. The many factors contributing to those outcomes are dissected, identifying those that can be controlled and used to improve performance.

Book Description
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

Book Description
This open access textbook provides a concise introduction to economic approaches and mathematical methods for the study of water allocation and distribution problems. Written in an accessible and straightforward style, it discusses and analyzes central issues in integrated water resource management, water tariffs, water markets, and transboundary water management. By illustrating the interplay between the hydrological cycle and the rules and institutions that govern today’s water allocation policies, the authors develop a modern perspective on water management. Moreover, the book presents an in-depth assessment of the political and ethical dimensions of water management and its institutional embeddedness, by discussing distribution issues and issues of the enforceability of human rights in managing water resources. Given its scope, the book will appeal to advanced undergraduate and graduate students of economics and engineering, as well as practitioners in the water sector, seeking a deeper understanding of economic approaches to the study of water management.

Book Description
The report aims to provide a conceptual framework to address food security under conditions of water scarcity in agriculture. It has been prepared by a team of FAO staff and consultants in the framework of the project "Coping with water scarcity - the role of agriculture", and has been discussed at an Expert Consultation meeting organized in FAO, Rome, during the period 14-16 December 2009 on the same subject. It was subsequently edited and revised, taking account of discussions in the Expert Consultation and materials presented to the meeting. The purpose of the Expert Consultation was to assist FAO to better design its water scarcity programme. In particular, the experts were requested to provide recommendations on the range of technical and policy options and associated principles that FAO should promote as part of an agricultural response to water scarcity in member countries. The document offers views on the conceptual framework on which FAO's water scarcity programme should be based, proposes a set of definitions associated with the concept of water scarcity, and indicates the main principles on which FAO should base its action in support to its member countries. At the meeting, experts were requested to review the draft document and provide feedback and recommendations for its finalization. Issues that were addressed in discussions included: 3⁄4 Water scarcity: agreement on key definitions. 3⁄4 The conceptualisation of water scarcity in ways that are meaningful for policy development and decision-making. 3⁄4 The quantification of water scarcity. . 3⁄4 Policy and technical response options available to ensure food security in conditions of water scarcity. . 3⁄4 Criteria and principles that should be used to establish priorities for action in response to water scarcity in agriculture and ensure effective and efficient water scarcity coping strategies.

Book Description
Owing to climate change related uncertainties and anticipated population growth, different parts of the developing and the developed world (particularly urban areas) are experiencing water shortages or flooding and security of fit-for-purpose supplies is becoming a major issue. The emphasis on decentralized alternative water supply systems has increased considerably. Most of the information on such systems is either scattered or focuses on large scale reuse with little consideration given to decentralized small to medium scale systems. Alternative Water Supply Systems brings together recent research into the available and innovative options and additionally shares experiences from a wide range of contexts from both developed and developing countries. Alternative Water Supply Systems covers technical, social, financial and institutional aspects associated with decentralized alternative water supply systems. These include systems for greywater recycling, rainwater harvesting, recovery of water through condensation and sewer mining. A number of case studies from the UK, the USA, Australia and the developing world are presented to discuss associated environmental and health implications. The book provides insights into a range of aspects associated with alternative water supply systems and an evidence base (through case studies) on potential water savings and trade-offs. The information organized in the book is aimed at facilitating wider uptake of context specific alternatives at a decentralized scale mainly in urban areas. This book is a key reference for postgraduate level students and researchers interested in environmental engineering, water resources management, urban planning and resource efficiency, water demand management, building service engineering and sustainable architecture. It provides practical insights for water professionals such as systems designers, operators, and decision makers responsible for planning and delivering sustainable water management in urban areas through the implementation of decentralized water recycling.
