Abstract
The impact of climate change is increasingly important for the design, construction, and maintenance of water sector infrastructure. Average global temperatures are on the rise, causing cycles of extreme weather: droughts and flooding are becoming common; seawater levels are rising; and many locations are considerably drier, impacting water sources such as lakes and rivers. Groundwater supplies are under stress due to decreasing precipitation rates and increasing extraction rates. Urban water systems must meet the demands of expanding industry needs and rapid population growth. Pollution adds to the growing threats to water resources, increasing treatment requirements for providing safe water to city residents. With two-thirds of the world's megacities located in regions that are vulnerable to the impacts of climate change, urban water utilities are facing an increasing need to improve the management of water resources and associated infrastructure. Diversifying sources of water supply will become increasingly important whether through the construction of new storage facilities, the appropriate and sustainable extraction of groundwater, water trading or conservation, or the use of recycled or desalinated water. This water note, based on the input of 20 large utilities around the world presents the perceptions, experiences, and approaches to addressing climate related challenges of urban areas in developing, middle income, and developed countries.

Publication Private Providers of Climate Change Services(World Bank, Washington, DC, 2010-06)Man-made climate change is affecting water infrastructure in all regions of the world, affecting large numbers of people in their daily life and the development of their societies. As part of the World Bank Water Anchor's analytical and advisory work on water and climate change, consultants have investigated how private sector services to infrastructure may address the challenges related to climate change while, at the same time, improving development opportunities for people. This report, which is one of the outcomes of the work, addresses the role of private providers of non-financial climate change-related services with relevance for water infrastructure. This report investigates to need for additional services with regard to climate change and analyzes the potential for the private sector in providing these services. The analysis focuses on the water sectors likely to be affected by climate change, that is, water resources management, irrigation and drainage, hydropower, coastal protection, flood protection, urban water supply, and sanitation as well as water quality. In addition, opportunities for mutual engagement of public and private agencies are analyzed and the perspectives of market development are explored. The central aim of the report is to deepen our understanding of the opportunities for engaging private providers of climate change services in climate change adaptation combined with socioeconomic development opportunities.Publication A Water Sector Assessment Report on the Countries of the Cooperation Council of the Arab States of the Gulf(Washington, DC, 2005-03)The main objective of the Water Sector Review in the member countries the Cooperation Council of the Arab States of the Gulf (GCC) is to (1) conduct a diagnosis of the current situation of the water sector, identify issues in the GCC region, evaluate the GCC governments' current water policies, and propose recommendations for improved Integrated Water Resources Management (IWRM) in Phase I of the study; (2) present key findings and recommendations at the GCC Water Conference in Bahrain, September 19-20, 2005, where Government officials, academic specialists and technical experts from the region would provide inputs to this study; and (3) if amenable to the GCC governments, conduct Phase II of the study to develop specific policies and action plans for more sustainable water resources management in individual GCC states.Publication Grow in Concert with Nature : Sustaining East Asia's Water Resources through Green Water Defense(Washington, DC: World Bank, 2012)As countries develop, the demand for water increases while water supply becomes less certain and is often not enough to meet demand. In general, pressures from both environment and human activities can increase the likelihood of water scarcity. Such pressures include increased socio-economic development and population growth, change in people's diets, competition for available water among different user sectors and growing climate variability. Climate change is likely to exacerbate the existing demand and supply stresses, particularly when more frequent and extreme droughts and floods, as well as rising sea level are becoming more evident. In temperate, sub-temperate regions, less rainfall and longer dry seasons are expected. In tropical areas, rainfall is predicted to be similar or greater in terms of annual average volumes, more intense and severe storms and seasonal droughts (IPCC, 2007). These pressures will test the effectiveness of water resource management systems in providing a consistent and secure water supply for all users, with minimum externalities. This study will assess advances in management practices, institutional and technological innovations for managing water scarcity sustainably under a changing climate. This study of 'sustaining East Asia's water resources through Green Water Defense (GWD) is a sub-study of the 'towards GWD in East Asia' study and is complemented by another sub-study 'green water defense for flood risk management in East Asia' that focuses on flood management in delta regions.Publication Dominican Republic - Environmental Priorities and Strategic Options : Country Environmental Analysis(Washington, DC, 2004-06-29)This report discusses the affects of rapid economic growth and increased urbanization on the environmental quality of the Dominican Republic's natural resource base (e.g., water resources management--water quality, quantity and watershed management and solid waste collection and disposal have become major environmental concerns). It notes that the lack of systematic data limits an accurate and detailed assessment of the scope of the problems, however, the consensus is that: (i) the overall poor quality of surface, groundwater and coastal water resources is the result of a lack of waste water management and agricultural run-off, causing health problems that disproportionately affect the poor; (ii) water scarcity is a regional problem resulting from poor demand management in irrigation, urban water supply and tourist infrastructure in drier regions; (iii) weak watershed management leads to soil erosion and amplifies the damage and frequency of flooding; and (4) the overall lack of solid waste management pollutes water sources, causes disease and is a nuisance for both inhabitants and visitors. To rectify these problems, the country established the Secretariat for the Environment and Natural Resources (SEMARN) in 2000, bringing all public institutions dealing with environmental issues under one roof. The World Bank has supported SEMARN through a Learning and Innovation Loan, and SEMARN has made significant progress since its inception by issuing environmental regulations, standards and impact assessment procedures, among other reforms and improvements. This report provides some indicative priority setting the Government could adopt or adjust in function of political and economic factors.Publication Water and Development : An Evaluation of World Bank Support, 1997-2007, Volume 2. Appendixes(Washington, DC: World Bank, 2010)The amount of available water has been constant for millennia, but over time the planet has added 6 billion people. Water is essential to human life and enterprise, and the increasing strains on available water resources threaten the mission of institutions dedicated to economic development. The ultimate goal is to achieve a sustainable balance between the resources available and the societal requirement for water. In this evaluation the Independent Evaluation Group (IEG) examines all the water-related projects financed by the World Bank between fiscal 1997 and the end of calendar 2007. Bank activities related to water are large, growing, and integrated. They include water resources management, water supply and sanitation, and activities related to agricultural water, industrial water, energy generation, and water in the environment. Through both lending and grants, the World Bank (the International Development Association and the International Bank for Reconstruction and Development, or IBRD) has supported countries in many water-related sectors. This evaluation examines the full scope of that support over the period from fiscal 1997 to the end of calendar 2007. More than 30 background studies prepared for the evaluation have analyzed Bank lending by thematic area and by activity type. The evaluation is by definition retrospective, but it identifies changes that will be necessary going forward, including those related to strengthening country-level institutions and increasing financial sustainability.

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 Doing Business 2014 : Understanding Regulations for Small and Medium-Size Enterprises(Washington, DC: World Bank Group, 2013-10-28)Eleventh in a series of annual reports comparing business regulation in 185 economies, Doing Business 2014 measures regulations affecting 11 areas of everyday business activity: Starting a business, Dealing with construction permits, Getting electricity, Registering property, Getting credit, Protecting investors, Paying taxes, Trading across borders, Enforcing contracts, Closing a business, Employing workers. The report updates all indicators as of June 1, 2013, ranks economies on their overall “ease of doing business”, and analyzes reforms to business regulation – identifying which economies are strengthening their business environment the most. The Doing Business reports illustrate how reforms in business regulations are being used to analyze economic outcomes for domestic entrepreneurs and for the wider economy. Doing Business is a flagship product by the World Bank and IFC that garners worldwide attention on regulatory barriers to entrepreneurship. More than 60 economies use the Doing Business indicators to shape reform agendas and monitor improvements on the ground. In addition, the Doing Business data has generated over 870 articles in peer-reviewed academic journals since its inception.Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.Publication Remarks to the Annual Meetings 2020 Development Committee(World Bank, Washington, DC, 2020-10-16)David Malpass, President of the World Bank Group, announced that the Board approved a fast track approach to emergency health support programs that now covers 111 countries. Most projects are well advanced, with average disbursement upward of 40 percent. The goal is to take broad, fast action early. The operational framework presented back in June has positioned the Bank to help countries address immediate health threats and social and economic impacts and maintain our focus on long-term development. The Bank is making good progress toward the 15-month target of 160 billion dollars in surge financing. Much of it is for the poorest countries and will take the form of grants or low-rate, long-maturity loans. IFC, through the Global Health Platform, will be providing financing to vaccine manufacturers to foster expanded production of COVID-19 vaccines in both part 1 and 2 countries, providing production is reserved for emerging markets. The Development Committee holds a unique place in the international architecture. It is the only global forum in which the Governments of developed countries and the Governments of developing countries, creditor countries and borrower countries, come together to discuss development and the ‘net transfer of resources to developing countries.’ The current International Financial Architecture system is skewed in favor of the rich and creditor countries. It is important that all voices are heard, so Malpass urged the Ministers of developing countries to use their voice and speak their minds today. Malpass urged consideration of how we can build a new approach to debt restructuring that allows for a fair relationship and balance between creditors and debtors. This will be critical in restoring growth in developing countries; and helping reverse the inequality.
