Resilient Shores: Vietnam’s Coastal Development Between Opportunity and Disaster Risk
(World Bank, Washington, DC, 2020-10-20)In a country that is among the most exposed to natural hazards, Vietnam’s coastline often bears the brunt. Typhoons, storm surges, riverine flooding, coastal erosion, droughts, or saline intrusion are all-too-familiar threats to most people living along the coast. Yet despite these risks, coastal regions host thriving economic sectors, providing livelihoods for a growing and rapidly urbanizing population. The coastal regions could be a powerful engine for Vietnam’s continued socioeconomic development, but rapid urbanization, economic growth, and climate change mean that disaster risks are bound to increase in the future. Although the government of Vietnam has made impressive progress in reducing and managing natural risks, current trends show that the work is far from complete. To guide effective action, this report provides an in-depth and multi-sectoral analysis of natural risks in coastal Vietnam and reviews current efforts in risk management, proposing a concrete action plan to balance the risks and opportunities of coastal development. These actions, if taken decisively, are an opportunity to strengthen the resilience of coastal communities and hence the prosperity of coming generations. -

Frontline: Preparing Healthcare Systems for Shocks from Disasters to Pandemics
(World Bank, Washington, DC, 2021-04-12)Healthcare systems are at the frontline of delivering critical care during emergencies. Yet, already before the COVID-19 pandemic, many countries were struggling to meet even routine demands for health care. Climate change, disasters, pandemics, and demographic changes will increase pressures on already strained health systems. To strengthen the resilience of health systems to shocks and pressures, this note outlines five principles and priority areas for action. (1) Foundations: Building the capacity of health systems to effectively manage routine demands is a prerequisite for increasing their resilience to shocks. (2) Health care facilities: Facilities must be prepared to meet surge demand during emergencies and protected against shocks, such as earthquakes or floods. (3) Health care systems: Coordinated regional and system-level responses and flexible solutions are key during emergencies. (4) National emergency management: Crisis response by the health sector must be coordinated with emergency management systems, including civil protection and risk financing. (5) Quality infrastructure: Resilient water, electricity, transport, and digital systems are essential for effective health services. The principles presented in this note can help to better prepare health systems to respond to a wide range of shocks, from seasonal demand surges, to pandemics, climate change, and disasters. -

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. -

From A Rocky Road to Smooth Sailing: Building Transport Resilience to Natural Disasters
(World Bank, Washington, DC, 2019-06)Reliable transport infrastructure is one of the backbones of a prosperous economy, providingaccess to markets, jobs and social services. Sustainable Development Goal 9 (SDG9) calls forincreased access to sustainable transport infrastructure in low- and middle-income countries.Collectively, these countries will need to spend between 0.5 percent and 3.3 percent of their GDPannually (157 billion to 1 trillion US Dollars) in new transport infrastructure by 2030 – plus an additional 1 percent to 2 percent of GDP to maintain their network – depending on their ambition and their efficiency in service delivery (Rozenberg and Fay, 2019). Because of the wide spatial distribution of transport infrastructure, many transport assets are exposed and vulnerable to natural hazards, increasing costs for national transport agencies and operators. During the 2015 floods in Tbilisi, Georgia, the repair of transport assets contributed approximately 60 percent of the total damage cost (GFDRR, 2015). In the 1995 earthquake in Kobe, Japan, accessibility as measured by the length of open networks directly after the shock dropped by 86 percent for highways and by 71 percent for railways (Kazama and Noda, 2012b). Such transport disruptions necessarily have direct impacts on the local economy. Employees face difficulties commuting, access to firms is disrupted for clients, interruptions in the supply chain inhibit production, and finished products cannot be easily shipped (Kajitani and Tatano, 2014). The paper, prepared as background material for the Lifelines report on infrastructure resilience, summarizes the main findings on the risk faced by transport networks and users as a result of natural disasters and climate change, and the main recommendations for building more resilient transport networks. It starts by describing how transport disruptions affect firms and households either directly and through supply chains. It then proposes a range of approaches and solutions for building more resilient transport networks, showing that the additional cost of resilience is not high if resources are well spent. Finally, it provides a set of practical recommendations. -

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. -

Adaptation Principles: A Guide for Designing Strategies for Climate Change Adaptation and Resilience
(World Bank, Washington, DC, 2020-11-17)Effective action on resilience and climate change adaptation can be a complex task—requiring coordinated efforts from the highest levels of government to individual households and firms. The Adaptation Principles offer a guide to effective climate change adaptation, containing hands-on guidance to the design, implementation and monitoring of national adaptation strategies. It specifies six guiding principles, which correspond to common policy domains: 1) Ensuring resilient foundations through rapid and inclusive development; 2) Facilitating the adaptation of firms and people; 3) Adapting land use and protecting critical public assets and services; 4) Increasing people’s capacity to cope with and recover from shocks; 5) Anticipating and managing macroeconomic and fiscal risks; 6) Ensuring effective implementation through prioritization and continuous monitoring. While outlining these universal Adaptation Principles, this guide shows that each country needs to tailor these actions to its specific needs and priorities. To guide this process, Adaptation Principles offers concrete and practical tools: Screening questions to identify the most urgent and effective actions, toolboxes illustrating common datasets and methodologies to support decisions, indicators to monitor and evaluate progress, and case studies on how the COVID-19 pandemic influences priorities in taking effective adaptation action.
