Abstract
As the wild tiger population in tropical Asia dropped from about 100,000 to 3,500 in the last century, the need to conserve tiger habitats poses a challenge for the Global Tiger Recovery Program. This paper develops and uses a high-resolution monthly forest clearing database for 74 tiger habitat areas in ten countries to investigate habitat threats for Bengal, Indochinese, Malayan and Sumatran tigers. The econometric model links forest habitat loss and forest clearing to profitability calculations that are affected by market expectations, environmental conditions and evolving patterns of settlement, among others. It uses new spatial panel estimation methods that allow for temporal and spatial autocorrelation. The econometric results emphasize the role of short-run market variables, including the exchange rate, real interest rate and prices of agricultural products in forest clearing, with considerable variation in the estimated timing for response and impact elasticities across countries. The results highlight a critical message for the conservation policy community: Changes in world agricultural-product markets and national financial policies have significant, measurable effects on tropical forest clearing, with variable time lags and degrees of responsiveness across countries. Measuring these effects and pinpointing areas at risk can provide valuable guidance for policymakers, conservation managers, and donor institutions.

    The Future of Poverty
    (Washington, DC: World Bank, 2025-07-15) Fajardo-Gonzalez, Johanna; Nguyen, Minh C.; Corral, Paul
    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.

    Central Bank Independence and Sovereign Borrowing
    (Washington, DC: World Bank, 2025-07-25) Athanasopoulos, Angelos; Fraccaroli, Nicolò; Kern, Andreas; Romelli, Davide
    This paper studies the impact of central bank independence on sovereign borrowing, using an index that captures institutional constraints on central bank lending to the government across 155 countries from 1972 to 2023. The findings show that tighter lending to the executive significantly reduces sovereign interest rates and raises the debt-to-gross domestic product ratio in developing countries. These effects reflect the executive’s improved ability to borrow at lower costs under greater central bank independence. The results are robust to multiple tests, but there are no significant effects in advanced economies. From a policy perspective, the results highlight the key role of independent central banks as catalysts for reducing governments’ borrowing costs and enhancing the government’s borrowing capacity.

    Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs
    (Washington, DC: World Bank, 2025-04-03) Vagliasindi, Maria; Gorgulu, Nisan
    This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.

    Crowding Out and Banking Crises
    (Washington, DC: World Bank, 2025-07-22) Hernando-Kaminsky, Pablo
    This paper studies the effect of government issuance on firm issuance during banking crises using transaction-level bond and loan data from 66 countries between 1991 and 2017. Governments rarely issue loans, preferring to issue in bond markets. In contrast, firms receive most of their financing from banks. During banking crises, as the supply of domestic loans decreases, firms switch to issuing bonds in domestic markets. The paper uses a novel instrument based on maturing debt to overcome the potential endogeneity of government issuance. The findings show that firms must compete with the government for funds in the domestic bond market and are crowded out from this market as a result. This happens not only in developing countries, but in advanced countries as well. The paper also shows that firms with the ability to tap international debt markets switch to these markets when crowding out occurs in domestic bond markets. Lastly, the paper shows that more developed domestic bond markets mitigate, but do not eliminate, the degree to which crowding out occurs.

    Designing and Analyzing Powerful Experiments
    (Washington, DC: World Bank, 2025-07-22) McKenzie, David
    This paper offers practical advice on how to improve statistical power in randomized experiments through choices and actions researchers can take at the design, implementation, and analysis stages. At the design stage, the choice of estimand, choice of treatment, and decisions that affect the residual variance and intra-cluster correlation can all affect power for a given sample size. At the implementation stage, researchers can boost power through increasing compliance with treatment, reducing attrition, and improving outcome measurement. At the analysis stage, power can be increased through using different test statistics or estimands, through the choice of control variables, and through incorporating informative priors in a Bayesian analysis. A key message is that it does not make sense to talk of “the” power of an experiment. A study can be well-powered for one outcome or estimand, but not others, and a fixed sample size can yield very different levels of power depending on researcher decisions.

    Protected Areas and Deforestation : New Results from High Resolution Panel Data
    (World Bank Group, Washington, DC, 2014-11) Blankespoor, Brian; Dasgupta, Susmita; Wheeler, David
    This paper investigates the effectiveness of protected areas in slowing tropical forest clearing in 64 countries in Asia/Pacific, Africa, and Latin America for the period 2001-2012. The investigation compares deforestation rates inside and within 10 kilometers outside the boundary of protected areas. Annual time series of these deforestation rates were constructed from recently published high-resolution data on forest clearing. For 4,028 parks, panel estimation based on a variety of park characteristics was conducted to test if deforestation is lower in protected areas because of their protected status, or if other factors explain the difference. For a sample of 726 parks established since 2002, a test also was conducted to investigate the effect of park establishment on protection. The findings suggest park size, national park status, and management by indigenous people all have significant association with effective protection across regions. For the Asia/Pacific region, the test offers compelling evidence that park establishment has a near-immediate and powerful effect.

    Impact of Climate Change and Aquatic Salinization on Fish Habitats and Poor Communities in Southwest Coastal Bangladesh and Bangladesh Sundarbans
    (World Bank, Washington, DC, 2016-03) Dasgupta, Susmita; Huq, Mainul; Mustafa, Md. Golam; Sobhan, Md Istiak; Wheeler, David
    Fisheries constitute an important source of livelihoods for tens of thousands of poor people in the southwest coastal region of Bangladesh living near the UNESCO Heritage Sundarbans mangrove forest, and they supply a significant portion of protein for millions. Among the various threats fisheries in the southwest coastal region and Sundarbans mangrove forest will face because of climate change, adverse impacts from increased aquatic salinity caused by sea level rise have been identified as one of the greatest challenges. This paper focuses on 83 fish species consumed by poor households in the region. Using the salinity tolerance range for each species, 27 alternative scenarios of climate change in 2050 were investigated to assess the possible impacts of climate change and sea level rise on aquatic salinity, fish species habitats, and the poor communities that consume the affected fish species. The results provide striking evidence that projected aquatic salinization may have an especially negative impact on poor households in the region. The estimates indicate that areas with poor populations that lose species are about six times more prevalent than areas gaining species.

    Safeguarding Important Areas of Natural Habitat in Mongolia alongside Economic Development
    (World Bank, Washington, DC, 2009-01) BirdLife Asia
    As market reforms to the Mongolian economy continue and the country enjoys rapid economic growth, the environment has entered a period of unprecedented pressure. Mining, infrastructure development and tourism development, in particular, are undergoing rapid expansion, and all pose risks to Mongolia's globally important biodiversity. In order to strengthen its safeguard review process in Mongolia, specifically implementation of its operational policy on natural habitats, the World Bank contracted Birdlife Asia to identify important areas of natural habitat in the country, and assess the extent to which these areas overlap with development plans. Birdlife Asia undertook this study in close collaboration with the Wildlife Science and Conservation Center (WSCC) of Mongolia. The study looked at the extent of overlap between sites of conservation importance on the one hand, and mining licenses, major infrastructure plans, and tourist camp locations on the other. It determined the scale of overlap at the national level, provided a strategic overview of potential impacts, and identified particular sites where there is cause for concern. Recommendations were made for how environmental issues arising might be addressed, including examples of guidance and best practice from outside of Mongolia.

    Environment Matters at the World Bank, 2009 Annual Review : Banking on Biodiversity
    (World Bank, 2010) World Bank
    This issue of environment matters celebrates the 2010 international year of biodiversity and describes some of the challenges and opportunities in protecting biodiversity for the benefit of humankind. From the world's highest mountain ranges to the lowland plains, and from the great oceans and coastal wetlands to agricultural landscapes, nations and communities rely on the bounty and services of natural ecosystems. Biological resources and the goods and ecosystem services they provide underpin every aspect of human life and livelihoods, from food and water security to general well-being and spiritual fulfillment. In many countries, it is the poorest of the poor who are most dependent on these benefits. Yet, as the Millennium Ecosystem Assessment showed, biodiversity is under severe threat, as ecosystems are being lost and degraded more rapidly and extensively than at any comparable period in our history. Habitat loss and fragmentation, overexploitation of resources, pollution, invasive alien species, and, increasingly, climate change will all lead to further biodiversity loss. One of the key challenges of the coming decades will be how to reconcile biodiversity conservation and development if we are to achieve the twin goals of poverty alleviation and a sustainable future for all. The World Bank is already a major global funder of biodiversity initiatives, including support to more than 624 projects in over 122 countries during the last 20 years. It is actively supporting national actions to safeguard biodiversity and improve natural resource management. Many of these projects have supported globally important protected areas, but efforts have also been made to mainstream biodiversity conservation in the production landscape. As well as national efforts, the Bank has supported numerous partnerships with international non-governmental organizations (NGOs) to promote global and regional biodiversity initiatives.

    Biodiversity, Climate Change, and Adaptation : Nature-Based Solutions from the World Bank Portfolio
    (Washington, DC, 2008-09) World Bank
    Climate change is a serious environmental challenge that could undermine the drive for sustainable development. Since the industrial revolution, the mean surface temperature of earth has increased an average of 1degree celsius per century due to the accumulation of greenhouse gases in the atmosphere. Furthermore, most of this change has occurred in the past 30 to 40 years, and the rate of increase is accelerating, with significant impacts both at a global scale and at local and regional levels. While it remains important to reduce greenhouse gas emissions and reverse climate change in the long run, many of the impacts of climate change are already in evidence. As a result, governments, communities, and civil society are increasingly concerned with anticipating the future effects of climate change while searching for strategies to mitigate, and adapt to, it's current effects.

    Lebanon Economic Monitor, Fall 2022
    (Washington, DC, 2022-11) World Bank
    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.

    (Washington, DC: World Bank, 2025-03-21) Luna-Bazaldua, Diego; Levin, Victoria; Liberman, Julia; Gala, Priyal Mukesh
    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.

    The Journey Ahead
    (Washington, DC: World Bank, 2024-10-31) Bossavie, Laurent; Garrote Sánchez, Daniel; Makovec, Mattia
    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.

    World Development Report 2006
    (Washington, DC, 2005) World Bank
    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.

    Argentina Country Climate and Development Report
    (World Bank, Washington, DC, 2022-11) World Bank Group
    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.
