Abstract
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 Yemen - Assessing the Impacts of Climate Change and Variability on the Water and Agricultural Sectors and the Policy Implications(World Bank, 2010-04-22)Yemen is particularly vulnerable to climate change and variability impacts because of its water dependence and current high levels of water stress. This natural resource challenge is compounded by demographic pressure, weak governance and institutions, and by a deteriorating economic situation. The economic and social outlook is not bright, and planning and international support will certainly be needed to help Yemen to adapt to the further stresses caused by climate change and variability. In the light of these challenges, the government has developed a National Adaptation Program of Action (NAPA). In support of this, the World Bank commissioned a series of studies of climate change in two phases: the first phase projected climate change scenarios for Yemen, and phase two assessed climate change impacts on the agricultural and water sectors, and outlined possible policy and program responses. The present study is essentially a digest of the work done to date, and is intended as a contribution to Government's process of assessing vulnerability and adaptation options by: (i) assessing possible impacts on the water balance and on agriculture and rural livelihoods; and (ii) reviewing adaptation options and the priorities for government policies, strategies and investments.Publication Toward Climate-Resilient Development in Nigeria(Washington, DC: World Bank, 2013-06-03)This book analyzes the risks to Nigeria's development prospects that climate change poses to agriculture, livestock, and water management. These sectors were chosen because they are central to achieving the growth, livelihood, and environmental objectives of Vision 20: 2020; and because they are already vulnerable to current climate variability. Since other sectors might also be affected, the findings of this research provide lower-bound estimates of overall climate change impacts. Agriculture accounts for about 40 percent of Nigeria's Gross Domestic product (GDP) and employs 70 percent of its people. Because virtually all production is rain-fed, agriculture is highly vulnerable to weather swings. It alerts us that increases in temperature, coupled with changes in precipitation patterns and hydrological regimes, can only exacerbate existing vulnerabilities. The book proposes 10 practical short-term priority actions, as well as complementary longer-term initiatives, that could help to mitigate the threat to vision 20: 2020 that climate change poses. Nigeria's vision can become a reality if the country moves promptly to become more climate-resilient. Climate variability is also undermining Nigeria's efforts to achieve energy security. Though dominated by thermal power, the country's energy mix is complemented by hydropower, which accounts for one-third of grid supply. Because dams are poorly maintained, current variability in rainfall results in power outages that affect both Nigeria's energy security and its growth potential. In particular, climate models converge in projecting that by mid-century water flows will increase for almost half the country, decrease in 10 percent of the country, and be uncertain over one-third of Nigeria's surface. The overall feasibility of Nigeria's hydropower potential is not in question. On grounds of energy diversification and low carbon co-benefits, exploiting the entire 12 gigawatts (GW) of hydropower potential should be considered. Nigeria has a number of actions and policy choices it might consider for building up its ability to achieve climate-resilient development.Publication Uncertainty and Climate Variability in the Design and Operation of Water Resources Projects : Examples and Case Studies(World Bank, Washington, DC, 2011-11)There are two common problems in flood hydrology: 1) estimate the return period for a given flood; and 2) estimate the flood for a given return period. A commonly used procedure to solve these problems is to fit a probability density function such as the Gumbel, Pearson type three or the generalized extreme value distributions to the historical data. The Pearson probability distribution was named after the statistician Pearson, it is also called the three-parameter gamma distribution. The Mann-Kendall test is a non-parametric test for identifying trends in time series data. The test compares the relative magnitudes of sample data rather than the data values them. One benefit of this test is that the data need not conform to any particular distribution. The data values are evaluated as an ordered time series. Each data value is compared to all subsequent data values. There are basically two approaches to downscale coupled climate model projections: statistical and dynamic downscaling.Publication Climate Trends and Impacts in China(World Bank, Washington, DC, 2013-09)This discussion paper summarizes observed and projected trends in extreme weather events, present-day climate variability, and future climate change and their impacts on China's different regions. Findings are presented from China's national assessment report on climate change (2007) and second national assessment report on climate change (2011) as well as other studies by Chinese and international experts. In addition to reviewing the physical climate science, the paper also looks at trends in economic damages in China from weather related hazards. The paper serves as background for a series of discussion papers on climate risk management and adaptation in China. The growing body of scientific evidence shows that China's climate is indeed changing, especially when climate is viewed at the regional level. Temperatures are rising, precipitation regimes are changing, and shifts have occurred in the distribution of extreme weather events. The effects of extreme weather events, present-day climate variability, and future climate change cut across many different sectors of China's economy. China's government estimates that direct economic losses from extreme weather events cost the country 1 to 3 percent of gross domestic product each year. As China's economy continues to grow, its exposure to weather-related hazards is expected to heighten, especially without policies to limit building in hazardous areas such as floodplains and alleviate non-climate pressures such as overuse of freshwater resources. Effective risk management policies and investments are crucial to reducing the sensitivity and increasing the resilience of the country to extreme weather, climate variability, and long-term climate change.Publication Adapting to Climate Change in Europe and Central Asia : Lessons from Recent Experiences and Suggested Future Directions(Washington, DC, 2012-06-28)Like other regions, Eastern Europe and Central Asia is vulnerable to climate change and its potential socioeconomic impacts. While all countries are facing warmer temperatures, a changing hydrology, and more extreme events (for example, floods and droughts) and are concerned about the level of greenhouse gases in the atmosphere, they differ in their financial and institutional capacities to respond. Therefore, especially for the most vulnerable countries in the region (for example, those in Central Asia and southern Europe), adapting to climate risk adds a new dimension to the challenges of development, but also provides an opportunity to revisit priorities and accelerate reforms. The Europe and Central Asia (ECA) Region of the World Bank has been actively working on climate-related projects and has advanced a number of initiatives in response to climate change since the 1990s. Nevertheless, up until a few years ago the region's focus was mainly on emissions reduction (mitigation), rather than on helping countries respond to existing or expected impacts from climate change through adjustments in natural or human systems. But more recently, adding focus on climate adaptation had led ECA to initiate a program of analytical work and pilot investment projects to help develop the information and knowledge base necessary to help build staff skills as well as better respond to client needs.

Publication World Development Report 1994(New York: Oxford University Press, 1994)World Development Report 1994, the seventeenth in this annual series, examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services - especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance. This report includes the World Development Indicators, which offer selected social and economic statistics for 132 countries.Publication Increasing Female Labor Force Participation(World Bank, Washington, DC, 2023-01)Gender gaps in labor force participation persist worldwide. Closing this gap can lead to sizeable gains for economies—a 20 percent increase in GDP per capita, on average. Female labor force participation (FLFP) remains low due to lack of skills, assets and networks, time-based constraints, limited mobility, gender discrimination in hiring and promotion, and restrictive gender norms. Effective evidence-backed policy options can increase FLFP. They include providing childcare services, disseminating information on work opportunities and returns to employment, training in socio-emotional skills, addressing norms by engaging partners and family members, and targeting women via social protection, safety net, and public-works programs. The World Bank Group actively supports countries in boosting FLFP through development policy lending, advisory and analytical work, and supporting reforms to address constraining contextual factors, including legal barriers, social norms, and gender-based violence. This note sheds light on an array of policy options that are effective or show promise in improving FLFP.Publication Poverty, Prosperity, and Planet Report 2024(Washington, DC: World Bank, 2024-10-15)The Poverty, Prosperity, and Planet Report 2024 is the latest edition of the series formerly known as Poverty and Shared Prosperity. The report emphasizes that reducing poverty and increasing shared prosperity must be achieved in ways that do not come at unacceptably high costs to the environment. The current “polycrisis”—where the multiple crises of slow economic growth, increased fragility, climate risks, and heightened uncertainty have come together at the same time—makes national development strategies and international cooperation difficult. Offering the first post-Coronavirus (COVID)-19 pandemic assessment of global progress on this interlinked agenda, the report finds that global poverty reduction has resumed but at a pace slower than before the COVID-19 crisis. Nearly 700 million people worldwide live in extreme poverty with less than US$2.15 per person per day. Progress has essentially plateaued amid lower economic growth and the impacts of COVID-19 and other crises. Today, extreme poverty is concentrated mostly in Sub-Saharan Africa and fragile settings. At a higher standard more typical of upper-middle-income countries—US$6.85 per person per day—almost one-half of the world is living in poverty. The report also provides evidence that the number of countries that have high levels of income inequality has declined considerably during the past two decades, but the pace of improvements in shared prosperity has slowed, and that inequality remains high in Latin America and the Caribbean and Sub-Saharan Africa. Worldwide, people’s incomes today would need to increase fivefold on average to reach a minimum prosperity threshold of US$25 per person per day. Where there has been progress in poverty reduction and shared prosperity, there is evidence of an increasing ability of countries to manage natural hazards, but climate risks are significantly higher in the poorest settings. Nearly one in five people globally is at risk of experiencing welfare losses due to an extreme weather event from which they will struggle to recover. The interconnected issues of climate change and poverty call for a united and inclusive effort from the global community. Development cooperation stakeholders—from governments, nongovernmental organizations, and the private sector to communities and citizens acting locally in every corner of the globe—hold pivotal roles in promoting fair and sustainable transitions. By emphasizing strategies that yield multiple benefits and diligently monitoring and addressing trade-offs, we can strive toward a future that is prosperous, equitable, and resilient.Publication World Development Report 2023: Migrants, Refugees, and Societies(Washington, DC : World Bank, 2023-04-25)Migration is a development challenge. About 184 million people—2.3 percent of the world’s population—live outside of their country of nationality. Almost half of them are in low- and middle-income countries. But what lies ahead? As the world struggles to cope with global economic imbalances, diverging demographic trends, and climate change, migration will become a necessity in the decades to come for countries at all levels of income. If managed well, migration can be a force for prosperity and can help achieve the United Nations’ Sustainable Development Goals. World Development Report 2023 proposes an innovative approach to maximize the development impacts of cross-border movements on both destination and origin countries and on migrants and refugees themselves. The framework it offers, drawn from labor economics and international law, rests on a “Match and Motive Matrix” that focuses on two factors: how closely migrants’ skills and attributes match the needs of destination countries and what motives underlie their movements. This approach enables policy makers to distinguish between different types of movements and to design migration policies for each. International cooperation will be critical to the effective management of migration.Publication Social Cohesion and Forced Displacement(Washington, DC: World Bank, 2022)This report presents new evidence from 26 background studies on forced displacement and social cohesion to expand the current knowledge base on how to prevent social conflict and promote social cohesion in forced displacement contexts. The background studies are geographically and methodologically diverse. They examine social cohesion in a variety of low-, middle-, and high-income countries across Africa, Asia, Central, and South America, and Europe. Building on this new evidence, the report provides lessons on how development investments and policies can reduce inequalities, alleviate social tensions, and promote social cohesion between and within displaced populations and host communities. Overall, the findings demonstrate that, while displacement can exacerbate existing inequalities and create new inequalities and the potential for conflict, especially in areas with strained services and limited economic opportunities, inclusive policies and development investments can effectively mitigate the negative effects of displacement and promote social cohesion.
