Rapid Urban Growth in Flood Zones: Global Evidence since 1985
(World Bank, Washington, DC, 2022-04)As countries rapidly urbanize, settlements are expanding into hazardous flood zones. This study provides a global analysis of spatial urbanization patterns and the evolution of flood exposure between 1985 and 2015. Using high-resolution annual data, it shows that settlements across the world grew by 85 percent to over 1.28 million square kilometers. In the same period, settlements exposed to the highest flood hazard level increased by 122 percent. In many regions, risky growth is outpacing safe growth, particularly in East Asia, where high-risk settlements have expanded 60 percent faster than safe ones. Developing countries are driving the recent growth of flood exposure: 36,500 square kilometers of settlements were built in the world’s highest-risk zones since 1985–82 percent of which are in low- and middle-income countries. In comparison, recent growth in high-income countries has been relatively slow and safe. These results document a divergence in countries’ exposure to flood hazards. Rather than adapting their exposure to climatic hazards, many countries are actively increasing their exposure. -

The RISE Framework
(World Bank, Washington, DC, 2022-01-17)The world has witnessed unparalleled economic progress in the last three decades. But success is not preordained, and several headwinds threaten this hard fought progress. Inequality is leaving many people and subgroups behind and excluding them from enjoying the benefits of this great economic expansion. More recently, the world has awakened to the reality of a new type of risk. The coronavirus disease 2019 (COVID-19) struck at a time when the world was healthier and wealthier than ever before. There is little disagreement over the need to enable a recovery that is fairer, safer, and more sustainable. This report describes how these ambitious objectives can be achieved by providing evidence based tools and information to guide countries to spend better and improve policies. It is in this context that this document presents policy guidance to identify and diagnose key development challenges and develop solutions to help countries build better. -

Building Back Better: Achieving Resilience through Stronger, Faster, and More Inclusive Post-Disaster Reconstruction
(World Bank, Washington, DC, 2018-06-18)The 2017 Unbreakable report made the case that disaster losses disproportionately affect poor people. The Caribbean hurricane season of 2017 was a tragic illustration of this. Two category 5 hurricanes wreaked destruction on numerous small islands, causing severe damages on islands like Barbuda, Dominica, and Saint Martin. The human cost of these disasters was immense, and the impact of this devastation was felt most strongly by poorer communities in the path of the storms. And yet, amidst the destruction it is essential to look forward and to build back better. In this 2018 report the authors explore how countries can strengthen their resilience to natural shocks through a better reconstruction process. Reconstruction needs to be strong, so that assets and livelihoods become less vulnerable to future shocks; fast, so that people can get back to their normal life as early as possible; and inclusive, so that nobody is left behind in the recovery process. The benefits of building back better could be very large – up to US$173 billion per year globally – and would be greatest among the communities and countries that are hit by disasters most intensely and frequently and that have limited coverage of social protection and financial inclusion. Small island states – because of their size, exposure, and vulnerability – are among the countries where building back better has the greatest potential. A stronger, faster, and more inclusive recovery would lead to an average reduction in disaster-related well-being losses of 59 percent in the 17 small island states covered in the report. -

Lifelines: The Resilient Infrastructure Opportunity
(Washington, DC: World Bank, 2019-06-19)From serving our most basic needs to enabling our most ambitious ventures in trade and technology, infrastructure services are essential for raising and maintaining people’s quality of life. Yet millions of people, especially in low- and middle-income countries, are facing the consequences of unreliable electricity grids, inadequate water and sanitation systems, and overstrained transport networks. Natural hazards magnify the challenges faced by these fragile systems. Building on a wide range of case studies, global empirical analyses, and modeling exercises, Lifelines lays out a framework for understanding infrastructure resilience—the ability of infrastructure systems to function and meet users’ needs during and after a natural shock—and it makes an economic case for building more resilient infrastructure. Lifelines concludes by identifying five obstacles to resilient infrastructure and offering concrete recommendations and specific actions that can be taken by governments, stakeholders, and the international community to improve the quality and resilience of these essential services, and thereby contribute to more resilient and prosperous societies. -

Stronger Power: Improving Power Sector Resilience to Natural Hazards
(World Bank, Washington, DC, 2019-06)The power sector is both highly vulnerable to natural hazards and a priority for any country'srecovery and reconstruction. After Hurricane Maria in Puerto Rico in 2017, most of the power gridwas down. One year and tens of billions of dollars later some customers were yet to be reconnected to the main grid. This type of long and widespread power outage has major consequences on people's health and well-being, for instance through lacking access to refrigeration for food and medicine, and on the ability of firms to produce and provide people with goods, services, jobs, and income. In most countries, the power system is designed to cope with high-frequency but relatively low impact events. Low-frequency, high-impact events – such as many natural disasters – are rarely considered fully, and the implementation of planned management measures is often patchy. Furthermore, the power system is a special kind of infrastructure due to the heterogeneity of the generation assets and its wide spatial distribution. The latter means that power systems are often exposed to natural hazards and sometimes to more than one hazard, leading to high repair costs when disasters strike. This paper, prepared as a sectoral note for the Lifelines report on infrastructure resilience, investigates the vulnerability of the power system to natural hazards and climate change, and provides recommendations to increase its resilience. It first describes how power outages are often the consequence of natural disasters and outlines the main vulnerabilities of the power sector. It then proposes a range of approaches and solutions for building a more resilient power sector – from increased robustness to greater flexibility – showing that the additional cost of resilience is not high if resources are well spent. Finally, it describes how emergency preparedness and disaster recovery encompass not only technical aspects, like asset strengthening or criticality analysis, but also "softer" skills, like governance, regulatory or capacity building, and education. -

Reforming Fossil Fuel Subsidies: Drivers, Barriers and the State of Progress
(Taylor and Francis, 2016-06-24)This article outlines the current state of affairs in fossil fuel subsidy reform, and highlights its contribution at the nexus of climate policy, fiscal stability and sustainable development. It discusses common definitions, provides quantitative estimates, and presents the evidence for key arguments in favour of subsidy reform. The main drivers and barriers for reform are also discussed, including the role of (low) oil prices and political economy challenges. Commitments to subsidy reform by the international community are reviewed, as well as the progress at the country level. Although fossil fuel subsidy reform indeed plays a critical role in climate policy, experience shows that the rationale for such reforms is determined in a complex environment of political economy challenges, macro-economic, fiscal and social factors, as well as external drivers such as energy prices. The article synthesizes the key principles for designing effective reforms and emphasizes that subsidy reforms cannot only yield fiscal relief, but should also contribute to long-term sustainable development objectives. Areas for future research are also identified.
