Abstract
The World Bank has recently developed a method to evaluate the effects of climate change on six hydrological indicators across 8951 basins of the world. The indicators are designed for decision-makers and stakeholders to consider climate risk when planning water resources and related infrastructure investments. Analysis of these hydrological indicators shows that, on average, mean annual runoff will decline in southern Europe; most of Africa; and in southern North America and most of Central and South America. Mean reference crop water deficit, on the other hand, combines temperature and precipitation and is anticipated to increase in nearly all locations globally due to rising global temperatures, with the most dramatic increases projected to occur in southern Europe, southeastern Asia, and parts of South America. These results suggest overall guidance on which regions to focus water infrastructure solutions that could address future runoff flow uncertainty. Most important, we find that uncertainty in projections of mean annual runoff and high runoff events is higher in poorer countries, and increases over time. Uncertainty increases over time for all income categories, but basins in the lower and lower-middle income categories are forecast to experience dramatically higher increases in uncertainty relative to those in the upper-middle and upper income categories. The enhanced understanding of the uncertainty of climate projections for the water sector that this work provides strongly support the adoption of rigorous approaches to infrastructure design under uncertainty, as well as design that incorporates a high degree of flexibility, in response to both risk of damage and opportunity to exploit water supply 'windfalls' that might result, but would require smart infrastructure investments to manage to the greatest benefit.

Publication Climate Variability and Change : A Basin Scale Indicator Approach to Understanding the Risk to Water Resources Development and Management(World Bank, Washington, DC, 2011-09)The impact of climate change is likely to have considerable implications for water resource planning, as well as adding to the risks to water infrastructure systems and effecting return on investments. Attention is increasingly being paid to adaptation strategies at the regional and basin level; however, the current paucity of information regarding the potential risk to hydrological systems at this scale presents a substantial challenge for effective water resources planning and investment. This study is intended to help bridge the gap between high-level climate change predictions and the needs of decision-makers, including World Bank Task Team Leaders, government agencies, investors, and national economic development planners, whose programs and investments will be affected by basin- and regional-level impacts of climate change on water resources and related infrastructures. This study evaluates the effects of climate change on six hydrological indicators across 8,413 basins in World Bank client countries. These indicators, mean annual runoff (MAR), basin yield, annual high flow, annual low flow, groundwater (base-flow), and reference crop water deficit, were chosen based on their relevance to the wide range of water resource development projects planned for the future. To generate a robust, high-resolution understanding of possible risk, this analysis examines relative changes in all variables from the historical baseline (1961 to 1999) to the 2030s and 2050s for the full range of 56 General Circulation Model (GCM) Special Report on Emissions Scenario (SRES) combinations evaluated in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4).Publication Reducing the Vulnerability of the Former Yugoslav Republic of Macedonia's Agricultural Systems to Climate Change : Impact Assessment and Adaptation Options(Washington, DC: World Bank, 2013-10-03)Agricultural production is inextricably tied to climate, making agriculture one of the most climate-sensitive of all economic sectors. In countries such as the Former Yugoslav Republic (FYR) of Macedonia, the risks of climate change for the agricultural sector are a particularly immediate and important problem because the majority of the rural population depends either directly or indirectly on agriculture for their livelihoods. Climate impacts can therefore undermine progress that has been made in poverty reduction and adversely impact food security and economic growth in vulnerable rural areas. In order to be effective, a plan for adapting the sector to climate change must strengthen both human capital and physical capital in their capacity. The need to adapt to climate change in all sectors is now on the agenda of national governments and development partners. As a result, development partners will continue to have an important role in enhancing the adaptive capacity of the Macedonian agricultural sector. Another key factor for FYR Macedonia's development of an adaptation plan for agriculture is furthering FYR Macedonia's work toward European Union (EU) accession, for which FYR Macedonia has been a candidate since 2005. The Macedonian government has already begun to focus on required EU reforms, including work on the agriculture strengthening and accession project with the World Bank. Along with these needed reforms, the EU encourages action toward climate change preparedness and adaptation. This report provides a menu of climate change adaptation options for the agriculture and water resources sectors, along with specific recommendations for adaptation actions that are tailored to distinct agro-ecological zones (AEZs) within FYR Macedonia. This report is structured as follows: chapter one gives current conditions for Macedonian agriculture and climate; chapter two presents design and methodology; chapter three deals with impacts of climate change on agriculture in FYR Macedonia; chapter four deals with identification of adaptation options for managing risk to FYR Macedonia's agricultural systems; chapter five presents cost-benefit analysis; and chapter six gives options to improve climate resilience of FYR Macedonia's agricultural sector.Publication Reducing the Vulnerability of Azerbaijan's Agricultural Systems to Climate Change : Impact Assessment and Adaptation Options(Washington, DC: World Bank, 2014-05-06)In countries such as Azerbaijan, the risks of climate change for the agricultural sector are a particularly immediate and important problem because the majority of the rural population depends either directly or indirectly on agriculture for their livelihoods. The need to adapt to climate change in all sectors is now on the agenda of the countries and development partners. International efforts to limit greenhouse gases and to mitigate climate change now and in the future will not be sufficient to prevent the harmful effects of temperature increases, changes in precipitation, and increased frequency and severity of extreme weather events. In response to these challenges, the World Bank and the government of Azerbaijan embarked on a joint study to identify and prioritize options for climate change adaptation of the agricultural sector. The study provides a framework for evaluating alternatives for investment in adaptation for the Azerbaijani government, potentially assisted by the donor community, and for the private agricultural sector. The framework has two critical components: (i) rigorous quantitative assessments, and (ii) structured discussion with local experts and farmers. The study recommends specific actions for policy makers ranked according to the results of the quantitative and qualitative analyses.Publication 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.Publication Reducing the Vulnerability of Uzbekistan's Agricultural Systems to Climate Change : Impact Assessment and Adaptation Options(Washington, DC: World Bank, 2013-10-03)Agricultural production is inextricably tied to climate, making agriculture one of the most climate-sensitive of all economic sectors. In countries such as Uzbekistan, the risks of climate change for the agricultural sector are a particularly immediate and important problem because the majority of the rural population depends either directly or indirectly on agriculture for their livelihoods. Recent trends in water availability and the presence of drought in Uzbekistan have underscored these risks, as has the presence of agricultural pests that may not have previously been found in Uzbekistan. The need to adapt to climate change in all sectors is on the agenda of national governments and development partners. The capacity to adapt to climatic changes, both in mitigating risks and in taking advantage of the opportunities that climate change can create, is in part dependent on financial resources. As a result, development partners will continue to have an important role in enhancing the adaptive capacity of the Uzbekistan agriculture sector. In response to these challenges, the World Bank and the government of Uzbekistan embarked on a joint study to identify and prioritize options for climate change adaptation of the agricultural sector. This report provides a menu of practical climate change adaptation options for the agriculture and water resources sectors, along with specific recommendations, which are tailored to three distinct agro-ecological zones (AEZs) within Uzbekistan, as well as over-arching actions at the national level. This report is organized as follows: chapter one gives current conditions for Uzbek agriculture and climate; chapter two presents design and methodology; chapter three deals with impacts of climate change on agriculture in Uzbekistan; chapter four presents identification of adaptation options for managing risk to Uzbekistan's agricultural systems; chapter five presents cost-benefit analysis; and chapter six gives options to improve climate resilience of Uzbekistan's agriculture sector.

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.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 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 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 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.
