Abstract
The Africa energy unit (AFTEG) of the World Bank has obtained financing from the trust fund for environmentally and socially sustainable development (TFESSD) funded by Finland and Norway for work towards understanding the impact of climate change on hydropower: the case of Cameroon. The development objective of this activity is: (i) to develop tools for assessing climate change impacts on the operation of hydraulic infrastructure such as regulating dams and hydropower plants in the Sanaga river basin, and (ii) to take steps towards an institutional framework for climate resilient water resources management in Cameroon. The aim of this initiative is to build resilience to climate risks into water management in general and hydropower development in Cameroon in particular. The study includes three components: (i) develop suitable climate change scenarios for the Sanaga basin, support the electricity development corporation (EDC) of Cameroon to develop a reliable hydrological model for the Sanaga river basin, and derive climate change impacts on the potential generation capacity in the Sanaga basin in the context of changing hydrology; (ii) assess the impact of climate change on the future operation of Lom Pangar dam and three other regulating dams in the Sanaga basin and support the establishment of an operational regime of hydraulic infrastructures in the Sanaga river basin, in a consultative manner with water users and taking into account equitable sharing of resources between users and environmental flows; and (iii) assess future impacts of climate change on water resources availability and management in Cameroon. This assessment also aims to provide an analytical base for increased dialogue on climate variability and change and on integrated management of water resources in Cameroon. The assessment will identify information and knowledge gaps and priorities for future studies and activities.

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 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 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 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 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 Lebanon Economic Monitor, Fall 2022(Washington, DC, 2022-11)The economy continues to contract, albeit at a somewhat slower pace. Public finances improved in 2021, but only because spending collapsed faster than revenue generation. Testament to the continued atrophy of Lebanon’s economy, the Lebanese Pound continues to depreciate sharply. The sharp deterioration in the currency continues to drive surging inflation, in triple digits since July 2020, impacting the poor and vulnerable the most. An unprecedented institutional vacuum will likely further delay any agreement on crisis resolution and much needed reforms; this includes prior actions as part of the April 2022 International Monetary Fund (IMF) staff-level agreement (SLA). Divergent views among key stakeholders on how to distribute the financial losses remains the main bottleneck for reaching an agreement on a comprehensive reform agenda. Lebanon needs to urgently adopt a domestic, equitable, and comprehensive solution that is predicated on: (i) addressing upfront the balance sheet impairments, (ii) restoring liquidity, and (iii) adhering to sound global practices of bail-in solutions based on a hierarchy of creditors (starting with banks’ shareholders) that protects small depositors.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 The Journey Ahead(Washington, DC: World Bank, 2024-10-31)The Journey Ahead: Supporting Successful Migration in Europe and Central Asia provides an in-depth analysis of international migration in Europe and Central Asia (ECA) and the implications for policy making. By identifying challenges and opportunities associated with migration in the region, it aims to inform a more nuanced, evidencebased debate on the costs and benefits of cross-border mobility. Using data-driven insights and new analysis, the report shows that migration has been an engine of prosperity and has helped address some of ECA’s demographic and socioeconomic disparities. Yet, migration’s full economic potential remains untapped. The report identifies multiple barriers keeping migration from achieving its full potential. Crucially, it argues that policies in both origin and destination countries can help maximize the development impacts of migration and effectively manage the economic, social, and political costs. Drawing from a wide range of literature, country experiences, and novel analysis, The Journey Ahead presents actionable policy options to enhance the benefits of migration for destination and origin countries and migrants themselves. Some measures can be taken unilaterally by countries, whereas others require close bilateral or regional coordination. The recommendations are tailored to different types of migration— forced displacement as well as high-skilled and low-skilled economic migration—and from the perspectives of both sending and receiving countries. This report serves as a comprehensive resource for governments, development partners, and other stakeholders throughout Europe and Central Asia, where the richness and diversity of migration experiences provide valuable insights for policy makers in other regions of the world.Publication Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.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.
