Pacific island countries are highly vulnerable to various natural disasters which are destructive, unpredictable and occur frequently. The frequency and scale of these shocks heightens the importance of medium-term economic and fiscal planning to minimize the adverse impact of disasters on economic development. This paper identifies the intensity of natural disasters for each country in the Pacific based on the distribution of damage and population affected by disasters, and estimates the impact of disasters on economic growth and international trade using a panel regression. The results show that “severe” disasters have a significant and negative impact on economic growth and lead to a deterioration of the fiscal and trade balance. We also find that the negative impact on growth is stronger for more intense disasters. Going further this paper proposes a simple and consistent method to adjust IMF staff’s economic projections and debt sustainability analysis for disaster shocks for the Pacific islands. Better incorporating the economic impact of natural disasters in the medium- and long-term economic planning would help policy makers improve fiscal policy decisions and to be better adapted and prepared for natural disasters.

Pacific island countries need to build their fiscal and economic resilience to climate change and natural disasters as these have lasting consequences on their livelihoods, economies, and fiscal balances. Climate change and natural disasters can have lasting consequences on livelihoods, economies, and fiscal balances-spanning immediate reconstruction costs and fiscal shocks to long-term halts in tourism and agriculture economies. Globally, the most exposed to these impacts are the Pacific island countries. The Asian Development Bank is working closely with its Pacific developing member countries to prepare for and respond to the effects of climate change and natural hazards. This publication examines the often-overlooked dimension of resilience planning-how to brace economies for shocks caused by climate change and hazard events. It analyzes the exposure and vulnerability of Pacific economies to disaster events and outlines key resources for building fiscal and economic resilience.

Natural disasters and climate change are interrelated macro-critical issues affecting all Pacific small states to varying degrees. In addition to their devastating human costs, these events damage growth prospects and worsen countries’ fiscal positions. This is the first cross-country IMF study assessing the impact of natural disasters on growth in the Pacific islands as a group. A panel VAR analysis suggests that, for damage and losses equivalent to 1 percent of GDP, growth drops by 0.7 percentage point in the year of the disaster. We also find that, during 1980-2014, trend growth was 0.7 percentage point lower than it would have been without natural disasters. The paper also discusses a multi-pillar framework to enhance resilience to natural disasters at the national, regional, and multilateral levels and the importance of enhancing countries’ risk-management capacities. It highlights how this approach can provide a more strategic and less ad hoc framework for strengthening both ex ante and ex post resilience and what role the IMF can play.

Economic Effects of Natural Disasters explores how natural disasters affect sources of economic growth and development. Using theoretical econometrics and real-world data, and drawing on advances in climate change economics, the book shows scholars and researchers how to use various research methods and techniques to investigate and respond to natural disasters. No other book presents empirical frameworks for the evaluation of the quality of macroeconomic research practice with a focus on climate change and natural disasters. Because many of these subjects are so large, different regions of the world use different approaches, hence this resource presents tailored economic applications and evidence. - Connects economic theories and empirical work in climate change to natural disaster research - Shows how advances in climate change and natural disaster research can be implemented in micro- and macroeconomic simulation models - Addresses structural changes in countries afflicted by climate change and natural disasters

This book explores economic concepts related to disaster losses, describes mechanisms that determine the economic consequences of a disaster, and reviews methodologies for making decisions regarding risk management and adaptation. The author addresses the need for better understanding of the consequences of disasters and reviews and analyzes three scientific debates on linkage between disaster risk management and adaptation to climate change. The first involves the existence and magnitude of long-term economic impact of natural disasters on development. The second is the disagreement over whether any development is the proper solution to high vulnerability to disaster risk. The third debate involves the difficulty of drawing connections between natural disasters and climate change and the challenge in managing them through an integrated strategy. The introduction describes economic views of disaster, including direct and indirect costs, output and welfare losses, and use of econometric tools to measure losses. The next section defines disaster risk, delineates between “good” and “bad” risk-taking, and discusses a pathway to balanced growth. A section entitled “Trends in Hazards and the Role of Climate Change” sets scenarios for climate change analysis, discusses statistical and physical models for downscaling global climate scenarios to extreme event scenarios, and considers how to consider extremes of hot and cold, storms, wind, drought and flood. Another section analyzes case studies on hurricanes and the US coastline; sea-level rises and storm surge in Copenhagen; and heavy precipitation in Mumbai. A section on Methodologies for disaster risk management includes a study on cost-benefit analysis of coastal protections in New Orleans, and one on early-warning systems in developing countries. The next section outlines decision-making in disaster risk management, including robust decision-making, No-regret and No-risk strategies; and strategies that reduce time horizons for decision-making. Among the conclusions is the assertion that risk management policies must recognize the benefits of risk-taking and avoid suppressing it entirely. The main message is that a combination of disaster-risk-reduction, resilience-building and adaptation policies can yield large potential gains and synergies.

This work combines research and empirical evidence on the economic costs of disasters with theoretical approaches. It provides new insights on how to assess and manage the costs and impacts of disaster prevention, mitigation, recovery and adaption, and much more.
