Abstract
Weather vulnerability is often assessed using historical data, but this can be very misleading in a world of changing climate. Weather refers to short-term atmospheric conditions, while climate is the weather averaged over a long period. With climate change, some places are becoming wetter, some drier, and extreme weather events, such as heatwaves, floods, droughts, and tropical cyclones, are becoming more likely. Hence, the nature of weather risks will vary considerably. Despite the magnitude of this shift, there is currently no widely accepted method for bringing climate change into catastrophe risk modeling. The objective of this note is to review, compare, and contrast the different techniques used in this literature to include climate change into vulnerability analysis. To do so, it summarizes recent research papers exploring how to bring climate change into catastrophe risk modeling. The note builds on this review to propose and explain a robust methodology and highlight its potential caveats. As such, this note is a first step towards unifying approaches and disseminating the analysis of climate change in vulnerability analysis. The method proposed in this note can be applied by researchers, economists, and public policy practitioners to study a wide range of topics, from the impact of climate change on diseases to stress-testing social protection programs.

Publication Environmental Reliance, Climate Exposure, and Vulnerability(World Bank, Washington, DC, 2015-11)This paper analyzes environmental reliance, poverty, and climate vulnerability among more than 7,300 households in forest adjacent communities in 24 developing countries. The data are from the detailed, quarterly income recording done by the Poverty Environment Network project. Observed income is combined with predicted income (based on households’ assets and other characteristics) to create four categories of households: income and asset poor (structurally poor), income rich and asset poor (stochastically non-poor), income poor and asset rich (stochastically poor), and income and asset rich (structurally non-poor). The income and asset poor generate 29 percent of their income from environmental resources, more than the other three categories. The income poor are more exposed to extreme and variable climate conditions. They tend to live in dryer (and hotter) villages in the dry forest zones, in wetter villages in the wet zones, and experience larger rainfall fluctuations. Among the self-reported income-generating responses to income shocks, extracting more environmental resources ranks second to seeking wage labor. Given high reliance on forest and other environmental resources, a concerning finding is that, in the Africa subsample (dominated by dry forests), the rate of forest loss is more than four times higher for the income asset poor compared with the income asset rich. Special attention should be given to the poorest households in dry areas, predominantly in Africa. They are (already) exposed to more extreme climate conditions, they suffer the highest forest loss, and the forest benefits are at risk in global warming scenarios.Publication The Poverty and Welfare Impacts of Climate Change Quantifying the Effects, Identifying the Adaptation Strategies(Washington, DC: World Bank, 2012-07-20)The continued decline in global poverty over the past 100 years particularly in the past three decades is a remarkable achievement. In 1981, 52 percent of the world population lived on less than $1.25 a day. By 2005, that rate had been cut in half, to 25.0 percent, and by 2008 to 22.2 percent (World Bank 2012). Preliminary estimates for 2010 indicate that the extreme poverty rate has fallen further still; if follow-up studies confirm this, the Millennium Development Goal (MDG) of halving world poverty will have been reached five years early (World Bank 2010). In recent years, poverty reduction has continued in most countries, even after the financial, food, and fuel shocks of 2008-09. Although poverty remains widespread in South Asia and Sub-Saharan Africa, progress has been substantial: extreme poverty fell in South Asia from 54 percent in 1990 to 36 percent in 2008 (World Bank 2012). In Sub-Saharan Africa, where population growth exceeded the rate of poverty reduction, the number of extremely poor people increased from 290 million in 1990 to 356 million in 2008, yet over 2005-08, the region's poverty rate nonetheless 'fell 4.8 percentage points to less than 50 percent the largest drop in Sub-Saharan Africa since international poverty rates have been computed,' according to the latest edition of the World Development Indicators (WDI) (World Bank 2012). Although progress has been slower at the $2-a-day poverty line, the WDI noted that an increase in the absolute number of people living on $1.25-$2.00 a day reflects both the upward movement from extreme poverty and 'the vulnerabilities still faced by a great many people in the world.' climate change is likely to reduce agricultural productivity, especially in the tropical regions, and to directly affect poor people's livelihood assets including health, access to water and other natural resources, homes, and infrastructure (World Bank 2010). Moreover, increasing climatic variability manifesting as more frequent and erratic weather extremes, or 'weather shocks' will likely make poor households even more vulnerable, which could in turn exacerbate the incidence, severity, and persistence of poverty in developing countries. This volume not only surveys the research terrain concerning the effects of climate change on poverty but also looks closely at vulnerable rural populations (in a developing country, Indonesia, and in the newly industrialized Mexico) where weather shocks have measurable short term if not immediate effects on the farming livelihoods many depend on for both income and subsistence. The low-income farmers of rice in Indonesia and of corn and other staple crops in Mexico are at the human forefront of climate change.Publication Social Dimensions of Climate Change : Equity and Vulnerability in a Warming World(World Bank, 2010)Climate change is widely acknowledged as foremost among the formidable challenges facing the international community in the 21st century. It poses challenges to fundamental elements of our understanding of appropriate goals for social and economic policy, such as the connection of prosperity, growth, equity, and sustainable development. This volume seeks to establish an agenda for research and action built on an enhanced understanding of the relationship between climate change and the key social dimensions of vulnerability, social justice, and equity. The volume is organized as follows. This introductory chapter first sets the scene by framing climate change as an issue of social justice at multiple levels, and by highlighting equity and vulnerability as the central organizing themes of an agenda on the social dimensions of climate change. Chapter two leads off with a review of existing theories and frameworks for understanding vulnerability, drawing out implications for pro-poor climate policy. Understanding the multilayered causal structure of vulnerability then can assist in identifying entry points for pro-poor climate policy at multiple levels. Building on such analytical approaches, chapters three and four, respectively, consider the implications of climate change for armed conflict and for migration. Those chapters are followed by a discussion of two of the most important social cleavages that characterize distinct forms of vulnerability to climate change and climate action: gender (chapter five) and ethnicity or indigenous identity (chapter six), in the latter case, focusing on the role of indigenous knowledge in crafting climate response measures in the Latin American and Caribbean region. Chapter seven highlights the important mediating role of local institutions in achieving more equitable, pro-poor outcomes from efforts to support adaptation to climate change. Chapter eight examines the implications of climate change for agrarian societies living in dry-land areas of the developing world, and chapter nine does the same for those living in urban centers. Chapter ten considers the role of social policy instruments in supporting pro-poor adaptation to climate change; and it argues for a focus on 'no-regrets' options that integrate adaptation with existing development approaches, albeit with modifications to take better account of the ways in which climate variables interact with other drivers of vulnerability. Finally, chapter eleven turns to the implications of climate policy and action for forest areas and forest people.Publication Reducing the Vulnerability of the Former Yugoslav Republic of Macedonia's Agricultural Systems to Climate Change : Impact Assessment and Adaptation Options(Washington, DC: World Bank, 2013-10-03)Agricultural production is inextricably tied to climate, making agriculture one of the most climate-sensitive of all economic sectors. In countries such as the Former Yugoslav Republic (FYR) of Macedonia, the risks of climate change for the agricultural sector are a particularly immediate and important problem because the majority of the rural population depends either directly or indirectly on agriculture for their livelihoods. Climate impacts can therefore undermine progress that has been made in poverty reduction and adversely impact food security and economic growth in vulnerable rural areas. In order to be effective, a plan for adapting the sector to climate change must strengthen both human capital and physical capital in their capacity. The need to adapt to climate change in all sectors is now on the agenda of national governments and development partners. As a result, development partners will continue to have an important role in enhancing the adaptive capacity of the Macedonian agricultural sector. Another key factor for FYR Macedonia's development of an adaptation plan for agriculture is furthering FYR Macedonia's work toward European Union (EU) accession, for which FYR Macedonia has been a candidate since 2005. The Macedonian government has already begun to focus on required EU reforms, including work on the agriculture strengthening and accession project with the World Bank. Along with these needed reforms, the EU encourages action toward climate change preparedness and adaptation. This report provides a menu of climate change adaptation options for the agriculture and water resources sectors, along with specific recommendations for adaptation actions that are tailored to distinct agro-ecological zones (AEZs) within FYR Macedonia. This report is structured as follows: chapter one gives current conditions for Macedonian agriculture and climate; chapter two presents design and methodology; chapter three deals with impacts of climate change on agriculture in FYR Macedonia; chapter four deals with identification of adaptation options for managing risk to FYR Macedonia's agricultural systems; chapter five presents cost-benefit analysis; and chapter six gives options to improve climate resilience of FYR Macedonia's agricultural sector.Publication The Republic of Armenia Climate Change and Agriculture Country Note(Washington, DC, 2012-06)This country note for Armenia is part of a series of country briefs that summarize information relevant to climate change and agriculture for three pilot countries in the Southern Caucasus Region, with a particular focus on climate and crop projections, adaptation options, policy development and institutional involvement. The note series has been developed to provide a baseline of knowledge on climate change and agriculture for the countries participating in the regional program on reducing vulnerability to climate change in Southern Caucasus Agricultural systems. This note for Armenia was shared with the government and other agricultural sector stakeholders and used as an engagement tool for a national awareness raising and consultation workshop, held in Yerevan in April 2012. Feedback and comments on the note from this consultation process have been incorporated into this updated version in collaboration with the Armenian Ministry of Agriculture.

Publication Governance in Sub-Saharan Africa in the 21st Century(Washington, DC: World Bank, 2024-03-04)What can be learned from the governance trajectory of African countries since the beginning of the 21st century What is the quality of governance on the African continent and how does it shape development The first decade of the millennium saw promising growth and poverty reduction in much of the continent. Yet, Sub-Saharan Africa has also been the stage of a stream of governance reform failures and policy reversals, and many countries continue to suffer from the consequences of poor governance. This paper explores the dynamics of governance reform on the continent over the past two decades and points to four key trends. First, effective state institutions, capable of maintaining peace, fostering growth, and delivering services, have developed unevenly. Second, progress has been made on enhancing the inclusiveness and accountability of institutions, but it remains constrained by the weakness of checks and balances and the persistence of patterns of centralized and exclusive power arrangements. Third, civic capacity has risen considerably, but the inability of institutions to respond to social expectations and political mobilization threatens to turn liberal civic engagement into distrust, populism, and radicalization. Fourth, the combination of these three trends contributes to the rise of political instability, which constitutes a major threat for the continent.Publication Statistical Performance Indicators and Index(World Bank, Washington, DC, 2021-03)The World Bank’s Statistical Capacity Index has been widely employed to measure country statistical capacity since its inception two decades ago. This paper builds on the existing advantages of the Statistical Capacity Index, conceptually and empirically, to offer new statistical performance indicators and the Statistical Performance Index, which can better measure a country’s statistical performance. The new index has clearer conceptual motivations, employs a stronger mathematical foundation, and significantly expands the number of indicators and countries covered. The paper further provides empirical evidence that illustrates the strong correlation of the new index with other commonly used development indicators of human capital, governance, poverty, and inequality. The framework can accommodate future directions to improve the index as the global data landscape evolvesPublication Economic Governance Improvements and Sovereign Financing Costs in Developing Countries(World Bank, Washington, DC, 2021-05)Low- and middle-income country governments are increasingly tapping the global debt capital markets. This is increasing the amount of finance available for development, but at a considerably higher cost than traditional external borrowing on concessional terms. Using a novel methodology based on estimating sovereign credit ratings using the Moody’s scorecard, and examining the associations between these ratings and the World Bank’s Country Policy and Institutional Assessment scores, this paper examines how making improvements in the quality of economic policies and institutions can help lower governments’ financing costs. This method aims to overcome the small-sample problem due to the number of rated developing country sovereigns still being relatively limited (although growing). Better economic governance Country Policy and Institutional Assessment scores are associated with better estimated ratings and materially lower financing costs; on average, improvements that are sufficient to increase the Country Policy and Institutional Assessment economic governance indicator score by one point are associated with interest costs that are lower by about 40 basis points, even setting aside the direct impact on ratings of better governance indicators. There are many reasons why improving governance is a good thing. Among them is the potential payoff to the public purse — savings of $40 million or more on a standard $1 billion, 10-year bond.Publication Evolution of the World Bank’s Thinking on Governance(World Bank, Washington, DC, 2016-01)The preparation work for the 2017 World Development Report on Governance and the Law in 2016 will coincide with the 25th anniversary of the World Bank’s decision to broaden its ongoing work on public sector management to embrace key issues of governance in the Bank’s borrowing countries. This paper provides a broad overview of the major Bank reports on governance that went through a review process at a sufficiently high level in the institution that they can reasonably be described as reflecting the Bank’s considered views at the time on the subject. The objective is to review the evolution of the Bank’s thinking on governance and assess the relevance and effectiveness of the work and its implications for the forthcoming World Development Report. Section two of this paper begins with a brief account of how the Bank came to focus on issues of governance, reviewing the major upheaval of governance in many of the Bank’s borrowing countries in the 1980s, the legal constraints the Articles of Agreement impose on the Bank’s work on governance, and a brief overview of the Bank’s initial policy statement on governance issued to the Bank’s Board in June 1991. Section three reviews major Bank work on governance as reflected in successive World Development Reports and examines the Bank’s analysis of the issue of corruption, reviewing how the Bank’s thinking on this symptom of poor governance has evolved. Section four steps back to assess what the Bank got right and some of the issues it missed or failed to address adequately. Section five draws attention to the dramatic changes experienced by the developing world in these past 25 years, and points to the need to better understand the implications of these changes for the governance context facing developing countries.Publication Data Transparency and Growth in Developing Economies during and after the Global Financial Crisis(World Bank, Washington, DC, 2020-12)The study explores the effects of data transparency on economic growth for developing economies over a unique time period—at the onset of the 2007–2009 global financial crisis and thereafter. Data transparency is defined as the timely production of credible statistics as measured by the Statistical Capacity Indicator. The paper finds that data transparency has a positive effect on real gross domestic product per capita during a period of considerable uncertainty. The estimates indicate an elasticity of the magnitude of 0.03 percent per year, which is much larger than the elasticity of trade openness and schooling in the estimation sample. The empirics employ a variety of econometric estimators, including dynamic panel and cross-sectional instrumental variables estimators, with the latter approach yielding a higher estimated elasticity. The findings are robust to the inclusion of several factors in addition to political institutions and exogenous commodity-price and external debt-financing shocks.
