Mapping the Resilience of International River Basins to Future Climate Change-Induced Water Variability, Volume 1. Main Report
(World Bank, Washington, DC, 2010-03)The study presented in this report aims to increase our understanding of the global distribution of treaty and River Basin Organization (RBO) mechanisms that may confer resilience to variability in the hydrological regime and how that distribution aligns with current and anticipated regimes. Some basins will experience greater changes in hydrologic variability regimes than others, and we specifically seek to identify country-basin combinations with greater exposure to variability and few or no treaty/RBO provisions to manage the transboundary impacts of that variability. To do this, we assessed all available international water treaties for specific treaty mechanisms, mapped the spatial distribution of these mechanisms and RBOs, and compared it to both the current variability regime and projections of future variability regimes driven by climate change. We then identified specific basins that may merit further study in light of their potential risk of future hydropolitical stress. By identifying these areas at the global scale, we can contribute to efforts aimed at anticipating future challenges in transboundary water management and suggesting specific measures to adapt existing or new water agreements to the effects of climate change. -

Reforming Urban Water Utilities in Western and Central Africa : Experiences with Public-Private Partnerships, Volume 2. Case Studies
(World Bank, Washington, DC, 2009-06)The Western and Central Africa has one of the longest experiences with public-private partnerships (PPPs) in the developing world, both for water supply and for combined power and water supply utilities. Cote d'Ivoire has a successful partnership dating from 1959, and over the last two decades as many as 15 countries (out of 23 in the region) have experimented with PPPs: eight for water supply operations alone and seven for combined power and water supply operations. This discussion paper documents the region's experience with PPPs for urban water supply in a comprehensive manner to help inform the current debate about the benefits brought by PPPs, in the context of helping Africa to achieve the Millennium Development Goals (MDG). Eleven PPPs have been studied, and detailed performance indicators are reported for six large cases - Cote d'Ivoire, Senegal, Niger, Mali, Burkina Faso, and Gabon, with at least four years of private operation. Through its successes and failures, the Western and Central African experience offers interesting lessons that other developing countries could reflect upon as they strive to improve the quality of urban water supply services, increase the efficiency of operations, and establish the financial credibility of the sector. -

Post-Construction Support and Sustainability in Community-Managed Rural Water Supply : Case Studies in Peru, Bolivia, and Ghana
(Washington, DC, 2009-06)This volume reports the main findings from a multi-country research project that was designed to develop a better understanding of how rural water supply systems are performing in developing countries. The author began the research in 2004 to investigate how the provision of support to communities after the construction of a rural water supply project affected project performance in the medium term. The author collected information from households, village water committees, focus groups of village residents, system operators, and key informants in 400 rural communities in Bolivia, Ghana, and Peru; in total, the author discussed community water supply issues with approximately 10,000 individuals in these communities. To the surprise, the author found the great majority of the village water systems were performing well. The findings on the factors influencing their sustainability will be of use to policy makers, investors, and managers in rural water supply. -

Strategic Environmental Assessment : Improving Water Resources Governance and Decision Making
(World Bank, Washington, DC, 2009-04)The overall goal of this report is to assist water resources and environment professionals within the Bank and client countries to use Strategic environmental assessment (SEAs) to effectively implement the principles of Integrated water resources management (IWRM). It (a) delineates environmental issues related IWRM; (b) identifies opportunities for SEAs to addressing these environmental issues; (c) uses the literature and ten Bank and non-Bank case studies to identify procedural and substantive factors and institutional drivers that lead to effective SEAs in the water sector at the policy, strategy, program, and plan levels; (d) reviews four national and state water policies to understand the inclusions of environment; (e) observes the introduction of SEAs in a developing country as an in-depth pilot study to identify practical issues arising from the introduction of SEAs for the water sector; and (f) recommends how the Bank can expand the use of SEAs to improve the integration of environmental issues in water resources investments. -

Watershed Management Approaches, Policies, and Operations : Lessons for Scaling Up
(World Bank, Washington, DC, 2008-05)The report begins with definitions of watersheds and watershed management, a characterization of the problem of watershed degradation, and a short history of watershed management operations and policies (Chapter 1). The following four chapters discuss the findings from experience with implementing watershed management programs over the last 20 years based both on the project review and on the literature. The second chapter discusses the findings on watershed management approaches and methodologies. The third chapter looks at findings on institutions for watershed management. The fourth chapter reviews the economics of watershed management. In the fifth chapter, issues of watershed management interactions with the environment and the water cycle are discussed, as well as the challenge of climate change. A brief sixth and the final chapter summarizes the principal conclusions and recommendations of the report. -

Emerging Public-Private Partnerships in Irrigation Development and Management
(World Bank, Washington, DC, 2007-05)The objective of this paper is to identify the possible role and opportunities for the private sector to participate with governments and farmers in developing and managing irrigation and drainage (I&D) infrastructure. Over the last 50 years, irrigated agriculture has been vital to meeting fast-rising food demand and has been key to poverty reduction. In the coming years the strong demographic demand for food is expected to continue, and intensified irrigated agriculture will have to provide close to 60 percent of the extra food. However, in recent years, the pace of irrigation expansion has been slowing, there has been less improvement in productivity, and water availability for irrigation is increasingly constrained. Governments have long led the expansion of large-scale irrigation, but performance has been suboptimal, and reforms that have been introduced have proved slow to improve efficiency and water service. Faced with this challenge, the I&D sector has been wrestling with three deep-seated problems: low water use efficiency, a high reliance on government financing, and poor standards of management and maintenance. Much of the search for improved investment and institutional models in I&D has been driven by the need to resolve these three problems. One solution that has been tested over the last two decades has been Participatory Irrigation Management (PIM) involving water user associations (WUAs) in the financing and management of schemes. This solution had its logical culmination in irrigation management transfer, the handover of responsibility for scheme operation and maintenance (O&M) to farmers and their organizations. This solution promised to relieve governments of both the fiscal burden and the responsibility for asset management and maintenance and to improve efficiency by empowering farmers. PIM has made impressive strides. However, efficiency has risen only marginally, and there are many schemes where O&M is beyond farmers' capacity. -

Economic Regulation of Urban Water and Sanitation Services : Some Practical Lessons
(World Bank, Washington, DC, 2007-04)This paper discusses the regulation of water and sanitation services in urban areas. Specifically, it explores ways of thinking about regulatory design as part of a wider, country-specific program to reform the way in which water supply and sanitation services are provided and paid for. In the past, regulatory advisers often focused on the need to introduce international best practice- generally in the form of an independent regulatory organization-to solve a wide range of performance problems. However, this approach was seldom straightforward, nor was it always successful. There is no one-size-fits-all regulatory design that can be reliably applied to resolve performance problems. Rather, regulation is best developed on a country-by-country basis through answering questions such as the following: a) What are the real sector problems, and which of these can regulation solve? b) What specific objectives is regulation aiming to achieve? c) What combination of organizations and instruments is most suitable and would work best for achieving these regulatory objectives? This paper is not intended to be a detailed guide for regulatory design. Rather, it discusses how to approach regulatory design. This approach encourages decision makers and their advisors to apply sound principles within country-specific settings, rather than advocate best-practice models without a thorough analysis of whether these are suitable for the country's context. The best combination of rules and institutions for setting tariffs and service standards3,-and indeed, the best reform options in general-will vary from country to country. Regulatory designers should select this combination by first focusing on the principal sector objectives and working with institutions that may already be responsible for achieving them. -

The Challenge of Reducing Non-Revenue Water in Developing Countries--How the Private Sector Can Help : A Look at Performance-Based Service Contracting
(World Bank, Washington, DC, 2006-12)This study explains that one of the major issues affecting water utilities in the developing world is the considerable difference between the amount of water put into the distribution system and the amount of water billed to consumers (also called "non-revenue water" [NRW]). High levels of NRW reflect huge volumes of water being lost through leaks, not being invoiced to customers, or both. It seriously affects the financial viability of water utilities through lost revenues and increased operational costs. In this report, a number of case studies, taken from some of the largest and most recent performance-based NRW contracts, are studied and discussed in terms of their technical and financial performance. Lessons learned from the case studies are analyzed, showing the potential benefits of NRW performance-based service contracting with the private sector. This paper was prepared as part of a Public-Private Infrastructure Advisory Facility (PPIAF)-financed study to investigate opportunities for the use of the private sector to assist water utilities in developing countries in reducing non-revenue water. This study indicates that the private sector help ailing public sector utilities in developing countries reduce NRW even though the performance- based service contracting approach described should not be seen as a substitute for overall sector reform. The case studies, while limited in number, provide examples of both good ideas and those to be avoided-but hopefully enough to help a utility and its consultants devise better cost-effective contractual arrangements suited to their conditions. -

Getting the Assumptions Right : Private Sector Participation Transaction Design and the Poor in Southwest Sri Lanka
(World Bank, Washington, DC, 2006-10)The need for reform in urban water and sanitation service delivery is urgent. Countries are making moves to achieve reforms, bringing in changes to the way they manage utilities, charge for water, and regulate the sector. This paper investigates how a set of basic assumptions on service coverage, service levels, tariffs, and subsidies in the proposed transactions in southwest Sri Lanka held up against consumer preferences. This paper provides the background information and describes the main features of the survey data. The paper then discusses a set of features that were used in the initial transaction design. This is followed by information on the impact of the different household preferences on these transaction features, and what this means in term of redesigning these features to ensure that the transaction would be more pro-poor. Conclusions and policy recommendations follow in the final section of this report.
