Abstract
This paper examines the costs, impacts, and cost-effectiveness of scaling up over five years the nutrition interventions included in Afghanistan’s Basic Package of Health Services (BPHS) as a first step in investing in the early years to build human capital. The total public investment required for the scale up to government-set program coverage levels is estimated to be 44 million US dollars per year over five years, or 1.49 US dollars per capita per year. Each dollar invested would yield at least 13 US dollars in economic returns and even under conservative assumptions regarding future economic growth, the economic benefits exceed the cost by six times which is 815 million US dollars over the productive lives of the beneficiaries. This scale up would prevent almost 25,000 child deaths and over 4,000 cases of stunting and avert a loss of 640,000 disability-adjusted life years (DALYs) and almost 90,000 cases years of anemia. Almost 100,000 more children would be exclusively breastfed. However, this scale-up would only have a marginal effect, a decrease of less than one-half percentage point on stunting prevalence because the current government-set target program coverage rates are very low for the preventive interventions that affect stunting. A substantially greater impact could be achieved if preventive interventions could be scaled to full program coverage levels, which would require less than 5 million US dollars more a year. This would triple the number of DALYs averted, double the number of deaths averted and avert almost eight times as many cases of stunting, resulting in a 2.6 percentage point decline in stunting over the five year period (from 41 percent to 38 percent). The prevalence of anemia in pregnant women could be reduced by 12 percentage points and the prevalence of exclusive breastfeeding could be increased by 18 percentage points. In addition, this investment is projected to generate economic benefits of 815 million US dollars over the productive lives of the beneficiaries. Each dollar invested would yield more than 13 US dollars in economic returns. Sensitivity analysis was conducted for the total cost, cost-effectiveness, and economic returns on investing in the BPHS nutrition interventions.

Publication An Investment Framework for Nutrition(Washington, DC: World Bank, 2017-04-12)The report estimates the costs, impacts and financing scenarios to achieve the World Health Assembly global nutrition targets for stunting, anemia in women, exclusive breastfeeding and the scaling up of the treatment of severe wasting among young children. To reach these four targets, the world needs $70 billion over 10 years to invest in high-impact nutrition-specific interventions. This investment would have enormous benefits: 65 million cases of stunting and 265 million cases of anemia in women would be prevented in 2025 as compared with the 2015 baseline. In addition, at least 91 million more children would be treated for severe wasting and 105 million additional babies would be exclusively breastfed during the first six months of life over 10 years. Altogether, achieving these targets would avert at least 3.7 million child deaths. Every dollar invested in this package of interventions would yield between $4 and $35 in economic returns, making investing in early nutrition one of the best value-for-money development actions. Although some of the targets—especially those for reducing stunting in children and anemia in women—are ambitious and will require concerted efforts in financing, scale-up, and sustained commitment, recent experience from several countries suggests that meeting these targets is feasible. These investments in the critical 1000 day window of early childhood are inalienable and portable and will pay lifelong dividends – not only for children directly affected but also for us all in the form of more robust societies – that will drive future economies.Publication Scaling Up Nutrition in Guinea-Bissau(World Bank, Washington, DC, 2017-01)This paper builds on global experience and Guinea-Bissau's specific context to identify an effective nutrition approach along with costs and benefits of key nutrition interventions. It is intended to help guide the selection of the most cost-effective interventions as well as strategies for scaling these up. We estimate that the costs and benefits of implementing 10 nutrition-specific interventions in all regions of Guinea-Bissau would require a public investment of USD 17 million over five years (with about USD 3 million needed to maintain the current coverage of the interventions and USD 14 million needed to expand the coverage to reach 90 percent of the population). The two key conclusions of this paper are, first, that investing in nutrition in Guinea-Bissau is cost-effective based on international standards and, second, that investments in nutrition can generate very substantial health and economic benefits, with one dollar spent on nutrition interventions resulting in about 10 dollars of returns over the productive lives of children covered by high-impact nutrition interventions. Economic productivity could potentially increase by USD 120 million (discounted at 3 percent) over the productive lives of the beneficiaries, with an impressive internal rate of return of 9 percent annually. Theses findings point to a powerful set of nutrition-specific interventions that represent a high cost-effective approach to reducing child malnutrition and stunting in Guinea-Bissau.Publication An Investment Framework for Nutrition in Kenya(World Bank, Washington, DC, 2016-12)This paper builds on global experience and Kenya’s specific context to identify an effective approach to scaling up nutrition and provide an estimate of costs and benefits of key nutrition interventions. It is intended to help guide the selection of the most cost-effective interventions as well as strategies for scaling up a package of interventions tailored to Kenya’s specific needs. The paper considers high-impact nutrition-specific interventions that largely rely on typical health sector delivery mechanisms. The authors estimate that the costs and benefits of implementing 11 critical nutrition-specific interventions will require a yearly public and donor investment of 76 million dollars. The expected benefits will be substantial: annually more than 455,000 disability adjusted life years (DALYs) will be averted, over 5,000 lives saved, and more than almost 700,000 cases of stunting among children under five averted. This investment will be very cost-effective with an estimated cost per DALY averted of 207 dollars cost per life saved of about 18,600 dollars and a cost per case of stunting averted of 135 dollars. Economic productivity can potentially increase by 458 million dollars over the productive lives of beneficiaries. However, the authors also calculate intermediate scale-up scenarios since it may not be feasible for the Government of Kenya or its partners to achieve full coverage in the near term. The authors compare the costs and benefits associated with three different scenarios: first, prioritizing counties, focusing the investment on counties with a high burden of stunting; second, prioritizing interventions, focusing on only a subset of the most effective interventions; and third, prioritizing both counties and interventions, delivering only the most effective subset of interventions to high-burden counties. The authors determined that the third scenario is the most cost-effective and least costly. Scaling up the most cost-effective interventions in 37 high-burden counties will avert almost 295,000 DALYs and save over 3,000 lives per year for an annual public and donor investment of 48 million dollars.Publication An Investment Framework for Nutrition in Kenya(Washington, DC: World Bank, 2016-12)This knowledge brief presents the costs of scaling up key effective nutrition interventions in Kenya and compares different scale-up scenarios to determine which one produces the best results for the lowest cost. The goal of the analysis is to inform program planning by identifying the most cost-effective packages of interventions and by leveraging additional resources from domestic budgets and development partners.Publication An Investment Framework for Nutrition in Zambia(World Bank, Washington, DC, 2016-11)This paper builds on global experience and Zambia's specific context to identify aneffective nutrition approach along with costs and benefits of key nutrition interventions. It isintended to help guide the selection of the most cost-effective interventions as well as strategiesfor scaling these up. The paper considers both relevant "nutrition-specific" interventions, largelydelivered through the health sector, and multisectoral "nutrition-sensitive" interventions, delivered through other sectors such as agriculture, education, and water and sanitation. We estimate that the costs and benefits of implementing 10 nutrition-specific interventions would require an annual public investment of $40.5 million and would avert over 112,000 DALYs, save over 2,800 lives, and prevent 62,000 cases of stunting. Economic productivity could potentially increase by $915 million annually over the productive lives of the beneficiaries, with an impressive internal rate of return of 32 percent. However, because it is unlikely that the Government of the Zambia or its partners will find the $40.5 million necessary each year to reach full coverage, we also consider scale-up scenarios based on considerations of their potential for impact, burden of stunting, resource requirements, and implementation capacity. The two scenarios that scale up the nine most cost-effective nutrition-specific interventions (excluding the public provision of complementary foods) are the most advantageous in terms of cost-effectiveness and resource requirements and would require $11 million to scale up to partial levels and $23 to scale up to full coverage levels. Among the 8 nutrition-specific interventions we consider, school-baseddeworming is low cost and effective. The interventions we reviewed in the agriculture sector areexpensive when compared to nutrition-specific interventions, although very little cost effectiveness data are available for the nutrition-sensitive interventions to make carefulcomparisons. These findings point to a powerful set of nutrition-specific interventions and acandidate list of nutrition-sensitive approaches that represent a highly cost-effective approach toreducing child malnutrition in Zambia.

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 Europe and Central Asia Economic Update, Fall 2024: Better Education for Stronger Growth(Washington, DC: World Bank, 2024-10-17)Economic growth in Europe and Central Asia (ECA) is likely to moderate from 3.5 percent in 2023 to 3.3 percent this year. This is significantly weaker than the 4.1 percent average growth in 2000-19. Growth this year is driven by expansionary fiscal policies and strong private consumption. External demand is less favorable because of weak economic expansion in major trading partners, like the European Union. Growth is likely to slow further in 2025, mostly because of the easing of expansion in the Russian Federation and Turkiye. This Europe and Central Asia Economic Update calls for a major overhaul of education systems across the region, particularly higher education, to unleash the talent needed to reinvigorate growth and boost convergence with high-income countries. Universities in the region suffer from poor management, outdated curricula, and inadequate funding and infrastructure. A mismatch between graduates' skills and the skills employers are seeking leads to wasted potential and contributes to the region's brain drain. Reversing the decline in the quality of education will require prioritizing improvements in teacher training, updated curricula, and investment in educational infrastructure. In higher education, reforms are needed to consolidate university systems, integrate them with research centers, and provide reskilling opportunities for adult workers.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 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.
