Abstract
Wildfires throughout western North America produce smoke plumes that can stretch across the agricultural regions of the American Midwest. Climate change is likely to increase the number and size of these fires and subsequent smoke plumes. These smoke plumes change direct, diffuse, and total sunlight during the crop growing season and consequently influence yields of both corn and soybeans. The analysis in this paper uses a twelve-year panel of county-level yields from all counties east of the 100th meridian combined with measures of exposure to smoke plumes of low and high density during the growing season. It shows that low-density plumes enhance yields, likely by increasing in the fraction of diffuse light, while high-density plumes decrease yields. Because there are more low-density plumes today, the net effect is a slight increase in yields on average. As climate change makes wildfires larger and more frequent, the overall impact of smoke on yields is expected to be substantially more negative.

Publication Intergenerational Income Mobility around the World(Washington, DC: World Bank, 2025-07-09)This paper introduces a new global database with estimates of intergenerational income mobility for 87 countries, covering 84 percent of the world’s population. This marks a notable expansion of the cross-country evidence base on income mobility, particularly among low- and middle-income countries. The estimates indicate that the negative association between income mobility and inequality (known as the Great Gatsby Curve) continues to hold across this wider range of countries. The database also reveals a positive association between income mobility and national income per capita, suggesting that countries achieve higher levels of intergenerational mobility as they grow richer.Publication The Impact of Trade Promotion Organizations on Exports(Washington, DC: World Bank, 2025-08-13)This paper examines the impact of trade promotion organizations on exports during the COVID-19 pandemic using a World Bank survey. The results suggest that increased trade promotion organization budgets significantly boosted exports during downturns but had no effect during the recovery phase. Interestingly, e-commerce programs adopted by trade promotion organizations negatively affected exports during downturns as they diverted resources away from productive support, especially for sectors not intensive in online trade. These findings suggest that countercyclical trade promotion organizations budgets may enhance trade resilience during similar global shocks.Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication The Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)Estimating the macroeconomic implications of climate change impacts and adaptation options is a topic of intense research. This paper presents a framework in the World Bank's macrostructural model to assess climate-related damages. This approach has been used in many Country Climate and Development Reports, a World Bank diagnostic that identifies priorities to ensure continued development in spite of climate change and climate policy objectives. The methodology captures a set of impact channels through which climate change affects the economy by (1) connecting a set of biophysical models to the macroeconomic model and (2) exploring a set of development and climate scenarios. The paper summarizes the results for five countries, highlighting the sources and magnitudes of their vulnerability --- with estimated gross domestic product losses in 2050 exceeding 10 percent of gross domestic product in some countries and scenarios, although only a small set of impact channels is included. The paper also presents estimates of the macroeconomic gains from sector-level adaptation interventions, considering their upfront costs and avoided climate impacts and finding significant net gross domestic product gains from adaptation opportunities identified in the Country Climate and Development Reports. Finally, the paper discusses the limits of current modeling approaches, and their complementarity with empirical approaches based on historical data series. The integrated modeling approach proposed in this paper can inform policymakers as they make proactive decisions on climate change adaptation and resilience.Publication Climate Vulnerability and Job Accessibility(Washington, DC: World Bank, 2025-08-11)Many developing cities are facing rapid population growth and extreme climate events. This paper examines the link between job accessibility and climate vulnerability, using data from Antananarivo, Madagascar, which frequently experiences flooding. As in other countries, the analysis finds that men’s commutes are longer than women’s, who tend to walk to work or use public transport. Even after controlling for observables and the potential endogeneity bias associated with commute time, the findings show that climate vulnerability negatively impacts wages, as people avoid commuting long to work due to anticipated potential climate risks. Building climate resilience into urban transport is therefore essential. As predicted by theory, the evidence also shows that the value of commuting is positive, and walking is disadvantageous. Motorized commuting yields higher returns, which could lead to overuse of private cars and taxis, posing decarbonization challenges.

Publication Climate Change and Agriculture in Latin America, 2020-2050 : Projected Impacts and Response to Adaptation Strategies(World Bank, Washington, DC, 2012-01)The impacts of climate change on agriculture are projected to be significant in coming decades, so response strategies, and their likely costs, should be evaluated now. That is why this study produced an open-access, crop-climate-economic impact modeling platform for Latin America and the Caribbean, that can be extended to other regions, then modified and improved by users as new crop, climate, and economic datasets become available. The new platform projects the likely impacts of agroclimatic factors on crop productivity, on the basis of climate projections from two general circulation models, and couples it with an economic model to derive and evaluate a range of climate-change scenarios and likely agricultural productivity and economic impacts over the next several decades.Publication Indigenous Peoples and Climate Change in Latin America and the Caribbean(World Bank, 2010)Indigenous peoples across Latin America and the Caribbean (LAC) already perceive and experience negative effects of climate change and variability. Although the overall economic impact of climate change on gross domestic product (GDP) is significant, what is particularly problematic is that it falls disproportionately on the poor including indigenous peoples, who constitute about 6.5 percent of the population in the region and are among its poorest and most vulnerable (Hall and Patrinos 2006). This book examines the social implications of climate change and climatic variability for indigenous communities in LAC and the options for improving their resilience and adaptability to these phenomena. By social implications, the authors mean direct and indirect effects in the broad sense of the word social, including factors contributing to human well-being, health, livelihoods, human agency, social organization, and social justice. This book, much of which relies on new empirical research, addresses specifically the situation of indigenous communities because our research showed them to be among the most vulnerable to the effects of climate change. A companion book (Verner 2010) provides information on the broader social dimensions of climate change in LAC and on policy options for addressing them. This book will help to place these impacts higher on the climate-change agenda and guide efforts to enhance indigenous peoples' rights and opportunities, whether by governments, indigenous peoples' organizations and their leaders, or non-state representatives.Publication Assessment of the Risk of Amazon Dieback(World Bank, 2011)The Amazon basin is a key component of the global carbon cycle. The old-growth rainforests in the basin represent storage of ~ 120 petagrams of carbon (Pg C) in their biomass. Annually, these tropical forests process approximately 18 Pg C through respiration and photosynthesis. This is more than twice the rate of global anthropogenic fossil fuel emissions. The basin is also the largest global repository of biodiversity and produces about 20 percent of the world's flow of fresh water into the oceans. Despite the large carbon dioxide (CO2) efflux from recent deforestation, the Amazon rainforest ecosystem is still considered to be a net carbon sinks of 0.8-1.1 Pg C per year because growth on average exceeds mortality (Phillips et al. 2008). However, current climate trends and human-induced deforestation may be transforming forest structure and behavior (Phillips et al. 2009). Increasing temperatures may accelerate respiration rates and thus carbon emissions from soils (Malhi and Grace 2000). High probabilities for modification in rainfall patterns (Malhi et al. 2008) and prolonged drought stress may lead to reductions in biomass density. Resulting changes in evapo-transpiration and therefore convective precipitation could further accelerate drought conditions and destabilize the tropical ecosystem as a whole, causing a reduction in its biomass carrying capacity or dieback. In turn, changes in the structure of the Amazon and its associated water cycle will have implications for the many endemic species it contains and result in changes at a continental scale. Clearly, with much at stake, if climate-induced damage alters the state of the Amazon ecosystem, there is a need to better understand its risk, process, and dynamics. The objective of this study is to assist in understanding the risk, process, and dynamics of potential Amazon dieback and its implications.Publication On Thin Ice : How Cutting Pollution Can Slow Warming and Save Lives(World Bank, Washington, DC, 2013-10)Climate change is happening faster and in a dramatically more visible way in the Earth's cryosphere than anywhere else on earth. Cryosphere is defined as elements of the Earth system containing water in its frozen state. The average temperature has risen here at over twice the global mean in the Arctic, Antarctic Peninsula, and much of the Himalayas and other mountain regions. This report summarizes the changes already being observed in the following five major cryosphere regions: the Andes, Antarctica, Arctic, East African Highlands, and the Himalayas. It then provides a science-based assessment of the impact of addressing methane and black carbon to reduce the risk to the global environment and human societies, especially for the most vulnerable populations. Chapter 2 provides a comprehensive assessment of the changes occurring in these five regions, based on the most recent literature, including the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (2013). Chapter 3 describes the pollution and climate nexus and the evolving knowledge of how methane and black carbon impact climate specifically in cryosphere regions. Chapter 4 presents the background and methods used for new modeling work conducted as part of this study, building extensively the United Nations Environment Programme/World Meteorological Organization Integrated Assessment of Black Carbon and Ozone (2010). Chapter 5 presents the results of the new modeling in these five major cryosphere regions as well as globally for health, crop impacts, and climate. Finally, Chapter 6 discusses the implications and new directions for the cryosphere regions emerging from these modeling results.Publication Weather and Climate Services in Europe and Central Asia : A Regional Review(Washington, DC : World Bank, 2008)This paper reviews the status of weather and climate services in Europe and Central Asia (ECA).Worldwide, the accuracy and value of weather and climate services are rising, bringing great economic benefits. However, many National Meteorological and Hydrological Services (NMHSs) in Europe and Central Asia are in decline. As a result, these potential gains are often missed. Much more could be done to mitigate weather disasters, support the productivity of smallholding and commercial agriculture, conserve energy, and promote safe aviation and transport by road and rail. Although NMHS capacity deficiencies are serious, they could be significantly remedied by relatively modest but sustained investments. Economic assessments indicate substantial benefit-to-cost ratios for such initiatives. A strategy for NMHS service improvement requires assessment of national climate, user needs, NMHS status and provision of services, and the economic benefits of an upgrade to weather and climate services. recommendations for agency modernization should include (a) a prioritized plan for improving data delivery to national users, (b) identification of the highest-priority infrastructure investments, and (c) a reasonable phasing plan for overall modernization.

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 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 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 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.
