Abstract
Evaluating the resilience of critical infrastructure systems (power, transport and water sectors) in the Caribbean requires geospatial data on infrastructure, hazard frequency, fragility, and downstream impact modeling. Ideally, resilience analyses can inform decision makers about their most vulnerable assets, losses that would have the largest impacts, and how to prioritize funding in the reality of limited budgets. The assessment of multiple assets within each sector is important to understand interdependencies and how loss of one system (e.g. transmission and distribution) can affect others (e.g. business operations). The interdependency between systems is also important to inform holistic planning. For example, roads are a key asset for water delivery in times of drought or pipe failure and for travel to hospitals or other critical facilities. Taking a systems perspective caN help resiliency planning by identifying the most vulnerable and important assets to reduce repeated failure of critical assets. In many countries with high exposure to natural hazards (such as small island states in the Caribbean), a recovery trap is caused by continued repair of repeatedly damaged assets. Climate change may cause this to worsen as the intensity and/or frequency of events including hurricanes, coastal surge, flood and heatwaves changes.

Publication Climate Resilient Ningbo Project : Local Resilience Action Plan, Volume 1. Final Report(Washington, DC, 2011-06)Ningbo serves as the Chinese pilot city for the World Bank Climate Resilient Cities (CRC) Program. The CRC program aims to, prepare local governments in the East Asia region to better understand the concepts and consequences of climate change; how climate change consequences contribute to urban vulnerabilities; and what is being done by city governments in East Asia and around the world to actively engage in learning capacity building, and capital investment programs for building sustainable, resilient communities. This local resilience action plan (LRAP) had four parts. Part one investigated natural hazards weather observations and climate models. Seven key climatic parameters were selected: temperature, rainfall, drought, heat wave, flood, tropical cyclone, and sea level rise. Part two examined how the city functions, and pursues socio-economic development through a city vulnerability assessment. The qualitative, city vulnerability assessment was based on five sectors- people, infrastructure, environment, economy, and government. Each sector was analyzed extensively on a range of issues, and compared to other similar Chinese cities to more accurately judge its performances. Part three is the gap analysis. It was performed to understand the government actions and their effectiveness to respond to natural disasters, and whether the current and planned policies and programs address the current and future climate change impacts and natural disasters. This part was supported by the following inventories: inventory of natural disasters, and inventory of policies and programs. Part four therefore was to develop recommendations for each of the city vulnerability sectors. The 70 plus recommendations are specific to Ningbo's vulnerabilities and risks. They are described briefly, intended to serve as an introduction. Feasibility studies are recommended before further action or implementation.Publication India - Vulnerability of Kolkata metropolitan area to increased precipitation in a changing climate(World Bank, 2011-06-01)This study aims to strengthen the understanding of the vulnerability of Kolkata from increased precipitation caused by climate change effects with a specific goal to: compile a data base with past weather related information and damage caused by extreme weather related episodes; develop hydrological, hydraulic, and storm drainage models to identify vulnerable areas and determine physical damage estimates resulting from climate change effects; assess monetary, social, and environmental impacts resulting from such climate change events; and strengthen local capabilities so that the planning process for Kolkata can account for climate related damage effects in future while analyzing all new projects. In this study, precipitation events in Kolkata based on available historical rainfall data for 25 years has been considered as a baseline (without climate change) scenario. The study modeled the impact of climate change on increased flooding in Kolkata Metropolitan Area (KMA). The main causes of flooding in KMA are intense precipitation, overtopping of the Hooghly River due to water inflow from local precipitation as well as that from the catchment area, and storm surge effects. Land subsidence was not included in the study as it was felt to be a localized problem in only a few pockets.Publication Adaptation to a Changing Climate in the Arab Countries : A Case for Adaptation Governance and Leadership in Building Climate Resilience(Washington, DC: World Bank, 2012-12-01)Adapting to climate change is not a new phenomenon for the Arab world. For thousands of years, the people in Arab countries have coped with the challenges of climate variability by adapting their survival strategies to changes in rainfall and temperature. Their experience has contributed significantly to the global knowledge on climate change and adaptation. But over the next century global climatic variability is predicted to increase, and Arab countries may well experience unprecedented extremes in climate. Temperatures may reach new highs, and in most places there may be a risk of less rainfall. Under these circumstances, Arab countries and their citizens will once again need to draw on their long experience of adapting to the environment to address the new challenges posed by climate change. This report prepared through a consultative process with Government and other stakeholders in the Arab world assesses the potential effects of climate change on the Arab region and outlines possible approaches and measures to prepare for its consequences. It offers ideas and suggestions for Arab policy makers as to what mitigating actions may be needed in rural and urban settings to safeguard key areas such as health, water, agriculture, and tourism. The report also analyzes the differing impacts of climate change, with special attention paid to gender, as a means of tailoring strategies to address specific vulnerabilities. The socioeconomic impact of climate change will likely vary from country to country, reflecting a country's coping capacity and its level of development. Countries that are wealthier and more economically diverse are generally expected to be more resilient. The report suggests that countries and households will need to diversify their production and income generation, integrate adaptation into all policy making and activities, and ensure a sustained national commitment to address the social, economic, and environmental consequences of climate variability. With these coordinated efforts, the Arab world can, as it has for centuries, successfully adapt and adjust to the challenges of a changing climate.Publication Adapting to Climate Change in Europe and Central Asia : Lessons from Recent Experiences and Suggested Future Directions(Washington, DC, 2012-06-28)Like other regions, Eastern Europe and Central Asia is vulnerable to climate change and its potential socioeconomic impacts. While all countries are facing warmer temperatures, a changing hydrology, and more extreme events (for example, floods and droughts) and are concerned about the level of greenhouse gases in the atmosphere, they differ in their financial and institutional capacities to respond. Therefore, especially for the most vulnerable countries in the region (for example, those in Central Asia and southern Europe), adapting to climate risk adds a new dimension to the challenges of development, but also provides an opportunity to revisit priorities and accelerate reforms. The Europe and Central Asia (ECA) Region of the World Bank has been actively working on climate-related projects and has advanced a number of initiatives in response to climate change since the 1990s. Nevertheless, up until a few years ago the region's focus was mainly on emissions reduction (mitigation), rather than on helping countries respond to existing or expected impacts from climate change through adjustments in natural or human systems. But more recently, adding focus on climate adaptation had led ECA to initiate a program of analytical work and pilot investment projects to help develop the information and knowledge base necessary to help build staff skills as well as better respond to client needs.Publication Methodology and Findings for the Exposure Analysis of the Chinese Wastewater Sector to Flooding and Earthquakes Hazards(World Bank, Washington, DC, 2019-06)This paper describes the methodology and findings for the extreme hazard exposure analysis of the Chinese wastewater sector to flooding and earthquakes hazards. This analysis is undertaken for changing flooding, under climate scenarios, and earthquake exposure of a spatially accurate wastewater treatment plants (WWTP) database for China, covering a total of 1,346 assets with additional attributes quantifying the treatment capacity and users dependent on each plant. For flooding, we apply and downscale a global river routing (CaMa-Flood) model that quantifies the change degree of flood exposures from the present time-period (1980-2005) to the near future time-period (2016-2035) to a far future time period (2036-2055). We find evidence that most climate models project increasing number of WWTP assets face climate-induced flood hazards in both the near and far future, potentially affecting as many as 208 million users by 2050. However, there are spatial and temporal variations from these projections which means that planning for resilient wastewater infrastructure requires more detailed understanding of the vulnerability attributes of WWTPs including their exact location, the number of users they serve as well as their flood protection standards. For earthquakes, we examine the exposure of WWTPs to earthquake hazards through both seismic shaking and induced liquefaction. Overall, we demonstrate the significant risk that earthquakes can have on the WWTP process -- especially on centralized systems. By considering liquefaction susceptibility in combination with shaking, we expose a number of WWTPs that face an increased level of exposure to damages following earthquakes compared to looking at shaking in isolation.

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.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 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 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.
