Abstract
When several municipalities unite in a single administrative structure - a process known as aggregation - they can lower the cost of utility services through economies of scale. Aggregation of water supply and sanitation (WSS) services is established practice in some countries and is likely to spread, as decentralization policies leave some service providers too small to be efficient or sustainable. Aggregation offers returns such as shared overhead and lower unit costs through bulk purchasing and pooled operations, plus other benefits that lower costs to customers or improved service at the current cost. Other benefits include greater access to financing, better distribution of skills, more opportunities for cross-subsidization and efficiency, access to new water resources, and new solutions to pollution problems. In 2005, the author studied 21 instances of aggregation of WSS services aggregations, looking for innovative models and factors that contributed to success. The practices author identified may help other countries aggregate municipal utilities.

Publication Mozambique : Public Expenditure Review for the Water Sector(Washington, DC, 2010-05)Reform is definitely under way in the water sector. Mozambique's goals and macro strategies are laid out in the Poverty Reduction Action Plan (PARPA) which is the main reference for water supply and sanitation policies. A water policy was established in 2007 which sets national targets for water supply and sanitation coverage, specifically, to achieve the millennium development goals. The sector also has a national strategy for the management of water resources. In addition, the different water subsectors have generated a large set of additional plans and strategies. The Medium-Term Fiscal Framework (MTFF) with specific proposals for each institution or agency in the sector, and the Economic and Social Plan for Rural Agriculture. The concurrence of these planning documents at the provincial and local levels requires strong coordination to ensure that the sector uses an integrated approach that balances the interests of the different sub-sectors with that of the overall sector. Yet, currently the sector still lacks a strong coordination mechanism. As a result of these policy changes, the Government's actual expenditure for the sector increased from $27 million in 2002 to $95 million in 2008; this is unlikely to be the total of funding available in the sector, but what could be substantiated from the government accounts. Donors supply most of funding in the form of investment funding. This public expenditure review focuses on the quantity and quality of Mozambique's public funding process to assess how well budget allocations for the water sector actually translate into better water and sanitation service delivery.Publication Rural Water Service : Is a Private National Operator a Viable Business Model?(World Bank, Washington, DC, 2002-06)In C�e d'Ivoire and Senegal water service is provided by privately operated national water utilities operating under enhanced lease contracts. While the national operators have performed relatively well within their service areas, their ability to expand service to rural areas has been limited. This Note focuses on the key factors shaping rural service expansion: reliance on cross-subsidies, the limited transfer of commercial risk to the private sector, and the lack of competition for serving new population centers beyond the utilities' existing areas of exclusivity. It compares the national model with those of more decentralized service provision for rural areas.Publication The Limits and Possibilities of Prepaid Water in Urban Africa(World Bank, Washington, DC, 2014-08)This study explores the potential of prepaid meters for serving urban poor communities. It provides urban utilities, oversight agencies, and other stakeholders in Africa with a basis for decision-making on the suitability, introduction, and management of such meters. The need for the assessment emerged from prepaid meters increasingly being utilized by water and sanitation utilities in developing countries, including World Bank clients. The technologies adopted have expanded over this period, but there has been a lack of consolidated data and analysis that capture the service delivery, operational efficiency, and access to services aspects of such systems across utilities and regions systematically. The review initially aimed to research experiences in six African countries from the perspective of their communities, as well as from water sector bodies, governments, and other investors. The number of case studies was increased to eight with the addition of Windhoek in Namibia and Nakuru in Kenya, as it became apparent that they may offer additional lessons. Windhoek, for example, is one of the prepaid water pioneers in Africa. The study specifically canvased the perspectives of customers, including market research and opinion surveys on people s experience and views of prepaid water in practice. Women and children were well represented in many of these groups. The analysis aimed to be robustly investigative, deliberately not advocating for prepaid systems in principle, or making firm recommendations, but rather offering balanced analysis and assessment, and considerations to inform policymakers and sector leaders, as well as other stakeholders who may face decisions or challenges on such systems. One of the key conceptual bases that the analysis identified was the need to differentiate between prepaid applications of prepaid system for standpipes, individual connections, and institutional and commercial customers each of which have different implications for their users, as well as for cost effectiveness. Utilities must be able to justify the investment in a prepayment system and its opportunity costs specific to the application they choose, and relative to alternative means of improving services.Publication 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.Publication Do Pro-Poor Policies Increase Water Coverage? An Analysis of Service Delivery in Kampala's Informal Settlements(Washington, DC, 2014)Uganda is one of the poorest countries in Africa with a gross national income (GNI) per capita in 2010 of United States (U.S.) $500 compared with the Sub-Saharan regional average of $1,170. Uganda's population growth of over 3 percent per year, one of the highest in the world, puts a considerable strain on public sector service delivery, not just for water and sanitation but also in other areas such as health, education, and transport. The aim of this study is to assess the impact of the pro-poor policies introduced by the National Water and Sewerage Corporation (NWSC) between 2004 and 2010, by analyzing the effectiveness, efficiency, and equity of these policies and strategies implemented by the Government of Uganda (GoU) and NWSC to increase coverage of urban water supply services in poor settlements. The study focuses exclusively on the area of Kampala city, the capital of Uganda, as this constitutes the largest service area of the NWSC - with approximately 60 percent of its connections and 64 percent of its revenues. The assessment of the impact of the pro-poor policies on the poor in Kampala is based on an analysis of the effectiveness, the efficiency, and the equity of these policies since 2004. The report is divided into the following six chapters: chapter one gives the introduction of the report and presents the objectives and methods used. Chapter two presents an overview of the water sector in Kampala, including the legal, institutional, and regulatory framework, a definition of poverty in Kampala and what this means for poor households. Chapter three describes the urban water sector policy and the strategy developed by the NWSC to expand services and improve financial performance. Chapter four analyzes in detail the impact of NWSC policies and water supply delivery mechanisms on services to poor households in Kampala. Chapter five contains the conclusions of the study. Chapter six contains recommendations for further analysis which can be undertaken by the NWSC, GoU, and or the World Bank.

Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.Publication Crime and Violence in Central America : A Development Challenge - Main Report(World Bank, 2011-01-01)Crime and violence are now a key development issue for Central American countries. In three nations El Salvador, Guatemala, and Honduras crime rates are among the top five in Latin America. This report argues that successful strategies require actions along multiple fronts, combining prevention and criminal justice reform, together with regional approaches in the areas of drug trafficking and firearms. It also argues that interventions should be evidence based, starting with a clear understanding of the risk factors involved and ending with a careful evaluation of how any planned action might affect future options. In addition, the design of national crime reduction plans and the establishment of national cross-sectoral crime commissions are important steps to coordinate the actions of different government branches, ease cross-sectoral collaboration and prioritize resource allocation. Of equal importance is the fact that national plans offer a vehicle for the involvement of civil society organizations, in which much of the expertise in violence prevention and rehabilitation resides. Prevention efforts need to be complemented by effective law enforcement. The required reforms are no longer primarily legislative in nature because all six countries have advanced toward more transparent adversarial criminal procedures. The second-generation reforms should instead help deliver on the promises of previous reforms by: (i) strengthening key institutions and improving the quality and timeliness of the services they provide to citizens; (ii) improving efficiency and effectiveness while respecting due process and human rights; (iii) ensuring accountability and addressing corruption; (iv) increasing inter-agency collaboration; and (v) improving access to justice, especially for poor and disenfranchised groups. Specific interventions reviewed in the report include: information systems and performance indicators as a prerequisite to improve inter-institutional coordination and information sharing mechanisms; an internal overhaul of court administration and case management to create rapid reaction, one-stop shops; the strengthening of entities that provide legal counseling to the poor and to women; and the promotion of alternative dispute-resolution mechanisms and the implementation of community policing programs.Publication Guide to the Debt Management Performance Assessment Tool(Washington, DC, 2008-02-05)The purpose of this document is to provide guidance and supplemental information to assist with country assessments of debt management performance, using the Debt Management Performance Assessment (DeMPA) tool. The DeMPA is a methodology used for assessing public debt management performance through a comprehensive set of 15 performance indicators spanning the full range of government Debt Management (DeM) functions. It is based on the principles set out in the International Monetary Fund (IMF) and World Bank guidelines for public debt management, initially published in 2001 and updated in 2003. It is modeled after the Public Expenditure and Financial Accountability (PEFA) framework for performance measurement of public financial management. The DeMPA has been designed to be a user-friendly tool to undertake an assessment of the strengths and weaknesses in government DeM practices. This guide provides additional background and supporting information so that a no specialist in the area of debt management may undertake a country assessment effectively. The guide can be used by assessors in preparing for and undertaking an assessment. It is particularly useful for understanding the rationale for the inclusion of the indicators, the scoring methodology, and the list of supporting documents or evidence required, and the questions that could be asked for the assessment.Publication The Mexican Social Protection System in Health(World Bank, Washington DC, 2013-01)With a population of 113 million and a per-capita Gross Domestic Product, or GDP of US$10,064 (current U.S. dollars), Mexico is one of the largest and highest-income countries in Latin America and the Caribbean (LAC). The country has benefited from sustained economic growth during the last decade, which was temporarily interrupted by the financial and economic crisis. Real GDP is projected to grow 3.8 percent and 3.6 percent in 2012 and 2013, respectively (International Monetary Fund, or IMF 2012). Despite this growth, poverty in the country remains high; with half of the population living below the national poverty line. The country is also highly heterogeneous, with large socioeconomic differences across states and across urban and rural areas. In 2010, while the extreme poverty ratio in the Federal District and the states of Colima and Nuevo Leon was below 3 percent, in Chiapas, Guerrero, and Oaxaca it was 25 percent or higher. These large regional differences are also found in other indicators of well-being, such as years of schooling, housing conditions, and access to social services. This case study assesses key features and achievements of the Social Protection System in Health (Sistema de Proteccion Social en Salud) in Mexico, and particularly of its main pillar, Popular Health Insurance (Seguro Popular, PHI). It analyzes the contribution of this policy to the establishment and implementation of universal health coverage in Mexico. In 2003, with the reform of the General Health Law, the PHI was institutionalized as a subsidized health insurance scheme open to the population not covered by the social security schemes. Today, the PHI covers all of its intended affiliates, about 52 million people
