Abstract
This paper combines remote-sensed data and individual child, mother, and household-level data from the Demographic and Health Surveys for 5 countries in Sub-Saharan Africa to design a prototype drought-contingent targeting framework for use in scarce-data contexts. To accomplish this, the paper: (i) develops simple and easy-to-communicate measures of drought shocks; (ii) shows that droughts have a large impact on child stunting in these five countries, comparable, in size, to the effects of mother’s illiteracy or a fall to a lower wealth quintile; and (iii) shows that, in this context, decision trees and regressions predict stunting as accurately as complex machine learning methods that are not interpretable.2 Taken together, the analysis lends support to the idea that a data-driven approach may contribute to the design of a transparent and easy-to-use drought-contingent targeting framework

Publication Adaptive Safety Nets for Rural Africa(World Bank, Washington, DC, 2019-12)This paper combines remote-sensed data and individual child-, mother-, and household-level data from the Demographic and Health Surveys for five countries in Sub-Saharan Africa (Malawi, Tanzania, Mozambique, Zambia, and Zimbabwe) to design a prototype drought-contingent targeting framework that may be used in scarce-data contexts. To accomplish this, the paper: (i) develops simple and easy-to-communicate measures of drought shocks; (ii) shows that droughts have a large impact on child stunting in these five countries -- comparable, in size, to the effects of mother's illiteracy and a fall to a lower wealth quintile; and (iii) shows that, in this context, decision trees and logistic regressions predict stunting as accurately (out-of-sample) as machine learning methods that are not interpretable. Taken together, the analysis lends support to the idea that a data-driven approach may contribute to the design of policies that mitigate the impact of climate change on the world's most vulnerable populations.Publication Improving Household Survey Instruments for Understanding Agricultural Household Adaptation to Climate Change : Water Stress and Variability(World Bank, Washington, DC, 2011-08-29)The Living Standards Measurement Study (LSMS) surveys which have collected information on many dimensions of household well-being for over 36 countries since 1980 are one of the most important data sources for informing policy making on development. The LSMS surveys have been used to assess household welfare, to understand household behavior, and to evaluate the welfare impact of various government policies. These surveys, however, lack well-designed instruments for understanding farm-level adaptation behavior to climate variability, in particular water resource variability and stress in agriculture. For the purpose of improving the quality, relevance and sustainability of smallholder agricultural data in Sub-Saharan Africa, the Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) project was started with a grant from the Bill and Melinda Gates Foundation, and is implemented by the LSMS team in the Development Research Group (DECRG) of the World Bank. Under the LSMS-ISA initiative, the World Bank is supporting seven countries in Sub-Saharan Africa, namely Ethiopia, Malawi, Mali, Niger, Nigeria, Tanzania, and Uganda, to establish systems of multi-topic, panel household surveys with a strong focus on agriculture. The surveys collect essential information to improve our understanding of economic development in Africa, particularly with regards to agriculture and linkages between farm and non-farm activities.Publication Gone with the Storm : Rainfall Shocks and Household Well-Being in Guatemala(World Bank Group, Washington, DC, 2015-01)This paper investigates the causal consequences of Tropical Storm Agatha (2010) -- the strongest tropical storm ever to strike Guatemala since rainfall records have been kept -- on household welfare. The analysis reveals substantial negative effects, particularly among urban households. Per capita consumption fell by 12.6 percent, raising poverty by 5.5 percentage points (an increase of 18 percent). The negative effects of the shock span other areas of human welfare. Households cut back on food consumption (10 percent or 43 to 108 fewer calories per person per day) and reduced expenditures on basic durables. These effects are related to a drop in income per capita (10 percent), mostly among salaried workers. Adults coped with the shock by increasing their labor supply (on the intensive margin) and simultaneously relying on the labor supply of their children and withdrawing them from school. Impact heterogeneity is associated with the intensity of the shock, food price inflation, and the timing of Agatha with respect to the harvest cycle of the main crops. The results are robust to placebo treatments, household migration, issues of measurement error, and different samples. The negative effects of the storm partly explain the increase in poverty seen in urban Guatemala between 2006 and 2011, which national authorities and analysts previously attributed solely to the collateral effects of the global financial crisis.Publication The Impacts of Climate Variability on Welfare in Rural Mexico(2011-02-01)This paper examines the impacts of weather shocks, defined as rainfall or growing degree days more than a standard deviation from their respective long-run means, on household consumption per capita and child height-for-age. The results reveal that the current risk-coping mechanisms are not effective in protecting these two dimensions of welfare from erratic weather patterns. These findings imply that the change in the patterns of climatic variability associated with climate change is likely to reduce the effectiveness of the current coping mechanisms even more and thus increase household vulnerability further. The results reveal that weather shocks have substantial (negative as well as positive) effects on welfare that vary across regions (North vs. Center and South) and socio-economic characteristics (education and gender). The heterogeneous impacts of climatic variability suggest that a "tailored" approach to designing programs aimed at decreasing the sensitivity and increasing the capacity of rural households to adapt to climate change in Mexico is likely to be more effective.Publication Water and Climate Adaptation Plan for the Sava River Basin(World Bank, Washington, DC, 2015-08)This report presents the water and climate adaptation plan (WATCAP) developed for the Sava river basin (SRB) as result of a study undertaken by the World Bank. The WATCAP is intended to help to bridge the gap between the climate change predictions for the SRB and the decision makers in current and planned water management investment projects that will be affected by changing climate trends. The purpose of the report is to: (i) assist stakeholders and decision makers in assessing and planning for the risks generated by climate change impacts on water resources; (ii) provide a basis for future plans and studies of adaptation to climate change impacts in the SRB; and (iii) stimulate cooperation and debate across the basin toward additional and more detailed studies on climate change impacts at the regional and basin scale. The SRB is projected to experience small increases in water use by the public water supply, industry, energy, and agricultural and irrigation sectors. However, it is widely expected that new hydropower plants (HPPs) will be constructed in the near future, making energy (primarily through hydropower) the most important water use in the SRB.

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 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 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.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.
