Abstract
Earth observation is a crucial source of accurate and up-to-date information of Earth’s natural and manmade environments that are critical when planning for, responding to, and mitigating the effects of natural hazards. Satellites that regularly collect images of the entire globe combined—with machine learning algorithms to process them more efficiently—have the potential to provide timely, standardized, verifiable, and scalable information. This report focuses on the use of Earth observation to identify built-up areas exposed to natural hazards. It describes the World Settlement Footprint (WSF) suite of derived datasets, developed by the German Aerospace Center (DLR) in collaboration with the European Space Agency (ESA), the Google Earth Engine team, and the World Bank. These gridded datasets capture the extent of built-up areas from 1985–2015 and again for 2019, estimated building heights, impervious surfaces, and estimated population. Earth observation derived information is particularly useful for standardized and recurring World Bank operations. The report looks at several World Bank operations, and the key insights provided through analysis incorporating the various WSF suite products.

Publication A Review of Disaster Risk Management for Fragility, Conflict and Violence Countries in the World Bank Portfolio(Washington, DC: World Bank, 2023-10-19)This portfolio review, led by the Global Facility for Disaster Reduction and Recovery's (GFDRR) Disaster-FCV Nexus thematic area, aims to contribute to the GFDRR’s overarching objective to help low- and middle-income countries understand and reduce their vulnerability to natural hazards and climate change. More specifically, the report aims to i) assess financing trends in World Bank (WBG) Disaster Risk Management (DRM) activities in Fragility, Conflict and Violence (FCV) countries over the fiscal year (FY) period 2012–2022, ii) understand key challenges for operational teams; identify and disseminate lessons and best practices, and iii) recommend ways to inform the GFDRR’s work on the Disaster FCV Nexus and integrate the nexus into WBG operations. The primary audience for this portfolio review is WBG task teams and managers, but it may also interest current and possible new donors to the GFDRR.Publication Global Rapid Post-Disaster Damage Estimation (GRADE) Report(Washington, DC: World Bank, 2024-08-05)This Global Rapid Post-Disaster Damage Estimation (GRADE) report provides a synopsis of the estimated direct economic damage in Saint Vincent and the Grenadines (SVG) due to the passage Hurricane Beryl. The report is based on a rapid and remote post disaster damage assessment that follows the established GRADE methodology. Hurricane Beryl passed over southern SVG on July 1, 2024. Wind speeds ranged from a Category 4 hurricane in the southern Grenadines, then lessening to the north with Tropical Storm force winds felt on the main island of Saint Vincent. The objective of this report is to provide an estimate of the direct economic damage to physical assets caused by Hurricane Beryl in Saint Vincent and the Grenadines (SVG) and to provide information on the spatial distribution of damages to support development of a roadmap for recovery and reconstruction.Publication Global Rapid Post-Disaster Damage Estimation (GRADE) Report(Washington, DC: World Bank, 2025-02-13)The objectives of this report include providing an estimate of the direct economic damage to physical assets caused by the December 17, 2024, earthquake in Vanuatu, providing information on the sectoral and spatial distribution of damage, and, in so doing, supporting the development of a roadmap for recovery and reconstruction. The data sources used are highlighted in Annex A. This GRADE assessment is intended as a rapid remote estimate prepared within a short timeframe to inform early decision-making. It is not intended as a substitute for detailed on-the-ground analysis, which may be conducted weeks and months after an event. The GRADE assessment should be interpreted as a first-order estimation of direct damages, albeit with a significant degree of reliability. While there is confidence in the overall damage estimates and distribution of damage, the confidence level at the individual asset level is low. Therefore, results are presented at aggregated levels.Publication Global Rapid Post-Disaster Damage Estimation (GRADE) Report: Cyclone Ditwah 2025, Sri Lanka(Washington, DC: World Bank, 2025-12-17)Cyclone Ditwah passed over the east of Sri Lanka between November 27 and 29 before moving into the Bay of Bengal. Sustained winds of 65 km/h were recorded, and rainfall was intense, causing devastating flooding. This Global Rapid Post-Disaster Damage Estimation (GRADE) report provides a synopsis of the estimated direct physical damage in Sri Lanka due to the passage of Cyclone Ditwah. The report is based on a rapid and remote post-disaster damage assessment which follows the established GRADE methodology (World Bank, 2018a) and is prepared within a short timeframe to inform early decision-making. It is not intended as a substitute for the detailed, sectoral, on-the-ground analysis which may be conducted in the weeks and months after a disaster. The objective of this report is to provide an estimate of the direct physical damage caused by Cyclone Ditwah in November 2025 in Sri Lanka. The assessment provides information on the spatial and sectoral distribution of damage to help calibrate other damage estimates and support the development of a roadmap for recovery and reconstruction.Publication Understanding Risk : Review of Open Source and Open Access Software Packages Available to Quanify Risk from Natural Hazards(World Bank Group, Washington, DC, 2014-11)The World Bank s disaster risk management (DRM) activities utilize a range of open access and open source computational modelling tools to quantify the risk posed by natural hazards. An important goal of these activities is to build capacity among national and local governments and international development professionals working in disaster risk management. A key decision in these activities is the choice of modelling tool that will be used to address the hazard, exposure, and/or risk question under consideration. This document presents an objective analysis of freely available hazard and risk modelling software in order to facilitate selection of appropriate tools for various DRM activities. There have been previous evaluations of freely available modelling tools across various natural hazards, but this is the first multi-hazard systematic review using a set of consistent criteria. The analysis covers hazard risk models for cyclone (wind), storm surge and tsunami, earthquake, and flood.

Publication Kyrgyz Republic Country Climate and Development Report(Washington, DC: World Bank, 2025-11-03)This Country Climate and Development Report (CCDR) on the Kyrgyz Republic aims to support the country’s development goals amid a changing climate. The CCDR considers two policy scenarios up to 2050: the business-as-usual (BAU) and high-growth scenarios. As it quantifies the likely impacts of climate change on the Kyrgyz economy between now and 2050, the report highlights key government actions to best prepare for and adapt to climate impacts (referred to as “with adaptation” measures), with a particular focus on the time horizon up to 2030. The CCDR also outlines a path to net zero emissions by 2050 (referred to as “with mitigation” measures, “decarbonization,” or, simply, “net zero 2050”), highlighting associated development co-benefits.Publication Jobs in a Changing Climate: Insights from World Bank Group Country Climate and Development Reports Covering 93 Economies(Washington, DC: World Bank, 2025-11-05)The World Bank Group’s Country Climate and Development Reports (CCDRs) provide a crosscutting look at how countries’ development prospects, and the job opportunities they offer to their people, can be threatened by climate impacts and supported by climate policies. Climate change and policies affect jobs through impacts on productivity, energy and material efficiency, and physical, human, and natural capital. They can also transform employment opportunities, especially through complementary measures that help workers and firms adapt to and benefit from new technologies and production practices. Prepared by the World Bank, the International Finance Corporation (IFC), and the Multilateral Investment Guarantee Agency (MIGA), CCDRs integrate country perspectives, climate science and economic modeling, private sector information, and policy analysis to assess how countries can successfully grow and develop their economies and create jobs despite increasing climate risks and while achieving their climate objectives and commitments. Each CCDR starts from the country’s development priorities, opportunities, and challenges, and is developed in close consultation with governments, businesses, and civil society, ensuring the recommendations reflect national priorities. By combining evidence on adaptation, resilience, and emissions pathways, CCDRs highlight where climate action can reinforce development and job creation, and where targeted policies are needed to manage risks and smooth labor market transitions. Taken together, these elements can help create local jobs, ensure economic transitions are just and inclusive, and equip workers and firms to navigate the disruptions and opportunities of a changing climate and changing technologies.Publication Comoros Country Climate and Development Report(Washington, DC: World Bank, 2025-06-18)The Union of the Comoros (The Comoros) has significant vulnerability to climate change-related risks but has considerable opportunities to strengthen preparedness and resilience against these challenges. According to the Notre Dame Global Adaptation Index, the Comoros is the 29th-most vulnerable country to climate change and the 163rd most ready to adapt (out of 191). The Comoros archipelago is exposed to many natural hazards that adversely affect the country’s natural capital, people, and physical infrastructure. In 2014, the economic cost of climate-related disasters was estimated at 5.7 million dollars annually, equivalent to 9.2 percent of Gross Domestic Product (GDP). Between 2018 and 2023, as many as 11 tropical depressions or cyclones impacted the country, with Cyclone Kenneth causing the greatest damage, equivalent to 14 percent of GDP, resulting in total economic growth falling from 3.6 percent in 2018 to 1.9 percent in 2019. More than 345,000 people (40 percent of the population) were affected by the cyclone, with 185,000 people experiencing severe impacts and 12,000 people displaced. However, there is an opportunity for the country to grow more robust and shock-responsive, and to establish pre-positioned funding mechanisms to enhance future crisis response efforts. For the Comoros, adaptation and climate-resilient development are the key climate change focus areas, with the country projected to face 836 million dollars 2050 in additional costs due to climate-related impacts. Current plans to adapt to the impacts of climate change in the Comoros include efforts to improve water management, strengthen coastal protection, and develop climate-smart agriculture practices. Given the country’s reliance on its natural resource base for economic growth and mobility, protection of these resources from climate change will be essential for promoting resilient growth and development. In addition to growing the adaptive capacity of the country’s natural resource sectors, strategic economic diversification will be important to help minimize future climate impacts, and development activities will need to be undertaken in such a way as to attract low-carbon co-benefits. The Union of the Comoros is committed to addressing climate change through its Nationally Determined Contribution (NDC) and national priorities. The country’s NDC (which was revised in 2021 for a ten-year horizon) sets ambitious targets, with a goal of reducing greenhouse gas emissions by 23 percent by 2030. The country also plans to significantly increase the share of renewable energy in its energy portfolio, reaching 33 MW by 2030. This will not only promote low-carbon development but also reduce the country’s dependency on imported oil and coal, which currently make up 95 percent of the energy mix. Additionally, the Comoros has declared its intention to increase CO2 removals by 47 percent by 2030, compared to BAU.Publication Mongolia Country Climate and Development Report(Washington, DC: World Bank, 2024-10-22)Mongolia’s development prospects are uniquely challenged by both the impacts of climate change and the global shift toward a low-carbon economy. The country’s efforts toward decarbonization pose significant challenges given the structurally high-emission intensity of its economy. While challenging, climate action also presents Mongolia with opportunities to achieve important development benefits. The effects of climate risks and the shift away from coal will have diverse impacts across different regions, communities, and socioeconomic levels. The report assesses the critical interconnections between Mongolia’s development ambitions and climate change action and identifies ways to transition to a more economically diversified, inclusive, and resilient development path. It highlights key climate and transition risks affecting Mongolia’s future development and presents a pathway to enhance climate mitigation and adaptation. The report also makes a case for strengthening policies to enhance resilience to climate change and ensure a just transition, particularly for the most vulnerable. The report is structured as follows: section 1 gives introduction. Section 2 delves into the linkages between development and climate in Mongolia and presents model-based findings on the economic and poverty impacts of climate change under different scenarios. Section 3 covers four in-depth sectoral analyses. The first two mainly focus on adaptation to climate change in the agriculture and water sectors. The third considers prospects for the extraction sector, while the fourth sectoral analysis focuses on decarbonizing power and heat generation. Section 4 shifts the focus to how the government can boost resilience for climate-vulnerable populations. Section 5 outlines options for mobilizing private and public financing and private investments to support the green transition. Section 6 examines the existing institutional and governance structure for climate action and presents recommendations to improve its effectiveness, and section 7 concludes with a framework for prioritizing the policy actions outlined in this report.Publication Guinea-Bissau Country Climate and Development Report(Washington, DC: World Bank, 2024-10-23)Guinea-Bissau is endowed with a wealth of natural resources, with the highest natural capital per capita in West Africa (US3,874 dollars per capita), which could be leveraged for sustainable and resilient growth. However, Guinea-Bissau faces significant development hurdles, such as high poverty rates, political instability, and economic challenges, including an over-reliance on cashew nuts. Rural poverty has increased, and the nation's infrastructure, education, and health care systems are underdeveloped. Climate change poses a severe threat, potentially impacting agriculture, fisheries, and infrastructure. Without adaptation, it could lead to a significant cut in real GDP per capita (minus 7.3 percent by 2050) and increase in poverty (with up to over 200,000 additional poor by 2050, that is, 5 percent of the expected population, in the worst scenario). The country's low greenhouse gas emissions are expected to rise, mainly due to agriculture and land-use changes, with deforestation being a major contributing factor. Although Guinea-Bissau is a low emitter, it has high mitigation ambitions, targeting a 30 percent reduction in greenhouse gas emissions by 2030. The Nationally Determined Contribution outlines significant climate actions, with initiatives focused on forest conservation, sustainable agriculture, and community development. However, the country's political instability, institutional weaknesses, and limited financial resources pose challenges to implementing these climate commitments, which depend heavily on external funding. The financial sector's underdevelopment and vulnerability to external shocks limit its ability to support green investments, though reforms could enhance resilience. Guinea-Bissau must consider its climate financing as development financing and vice-versa, engage the private sector, and integrate climate goals with national development plans to ensure a sustainable future. Concessional climate financing is vital due to the underdeveloped financial sector and the government’s limited borrowing capacity. Addressing Guinea-Bissau's vulnerability to climate change and its structural issues requires a cohesive approach that integrates development and climate strategies. This could involve improving governance, diversifying the economy, protecting natural capital, developing human capital, and investing in sustainable agriculture and infrastructure. The transition to a more sustainable and inclusive development pathway that supports economic growth is possible, but requires focusing on key strategic sectors, enhancing institutional capacity, and creating the conditions to mobilize finance. As a highly vulnerable country, there are myriad needs in the different sectors; however, to be more efficient and effective, Guinea-Bissau should prioritize actions in a few sectors, especially actions on biodiversity, agriculture, and social protection. Low carbon development, especially in energy and forestry sectors, could provide cost-efficient solutions and attract climate finance, including from the private sector, which will support the overall development agenda.
