Mental Health Consequences and Social Issues After the Fukushima Disaster.

Abstract: The Great East Japan Earthquake and subsequent nuclear power plant accident caused multidimensional and long-term effects on the mental health condition of people living in Fukushima. In this article, focusing on the influence of the nuclear disaster, we present an overview of studies regarding the psychosocial consequences of people in Fukushima. Studies revealed that the experiences of the explosions at the plant as well as the tsunami are deeply embedded in their memory, leading to posttraumatic responses. Chronic physical diseases, worries about livelihood, lost jobs, lost social ties, and concerns about compensation were also associated with posttraumatic responses. Furthermore, the radioactive fallout brought chronic anxiety regarding physical risks of radiation exposure to people, especially young mothers. People often have different opinions about the radiation risk and their own future plans, resulting in a reduction in the resilience that communities and families had before the disaster. In addition, such weakened community resilience may produce a significant increase in disaster-related suicide in Fukushima. Specific social issues, such as "radiation stigma" among the public and self-stigma among evacuees, that are never seen with other natural disasters also increased in Fukushima.

Infrastructure Interdependency and the Creation of a Normal Disaster: The Case of Hurricane Katrina and the City of New Orleans

Abstract: This article examines the impact of Hurricane Katrina on the infrastructure of the City of New Orleans Hurricane Katrina set in motion a devastating series of failures in the critical infrastructure of the City of New Orleans and the surrounding region The authors argue that Katrina can be viewed as a “normal” disaster, involving the complex interaction of interdependent infrastructures resulting in the unanticipated failure of multiple infrastructure systems Key characteristics of infrastructure interdependencies are explored in relation to the case of Hurricane Katrina and New Orleans Understanding the nature of normal disasters and the tight coupling of infrastructure systems provides infrastructure managers with important lessons These lessons involve the need for risk and vulnerability assessment; coordination, cooperation, and communication; and the need for flexible response to disasters

The Political Economy of Natural Disaster Damage

Abstract: Economic damage from natural hazards can sometimes be prevented and always mitigated. However, private individuals tend to underinvest in such measures due to problems of collective action, information asymmetry and myopic behavior. Governments, which can in principle correct these market failures, themselves face incentives to underinvest in costly disaster prevention policies and damage mitigation regulations. Yet, disaster damage varies greatly across countries. We argue that rational actors will invest more in trying to prevent and mitigate damage the larger a country’s propensity to experience frequent and strong natural hazards. Accordingly, economic loss from an actually occurring disaster will be smaller the larger a country’s disaster propensity – holding everything else equal, such as hazard magnitude, the country’s total wealth and per capita income. At the same time, damage is not entirely preventable and smaller losses tend to be random. Disaster propensity will therefore have a larger marginal effect on larger predicted damages than on smaller ones. We employ quantile regression analysis in a global sample to test these predictions, focusing on the three disaster types causing the vast majority of damage worldwide: earthquakes, floods and tropical cyclones.

Twitter Early Tsunami Warning System: A Case Study in Indonesia's Natural Disaster Management

Abstract: Twitter demonstrated its value as a viable substitute to traditional communication channels during the recent disasters. However, little is written about Twitter in government for an early disaster warning system. In this exploratory empirical research, we aim to address the question: How does the government use Twitter to inform the public about disaster hazards and vulnerability? Case study and tweets content analysis are conducted on Indonesia's Twitter early tsunami warning system to answer the question in the context of the three earthquakes occurred off the west coast of Sumatra during the period of 2010-2012. Data are collected from egovernment websites of agencies involved in disaster preparedness and response. This research concludes that the Twitter-based warning system demonstrated its value as a viable complement to Indonesia's InaTEWS - a comprehensive disaster information management system for governments - by informing the public and creating public value through its communication speed, reach and information quality.

The Economic Impacts of Natural Disasters

Abstract: Presents six national case studies: Bangladesh, Vietnam, India, Nicaragua, Japan, and the Netherlands Since the turn of the millennium, more than one million people have been killed and 2.3 billion others have been directly affected by natural disasters around the world. In cases like the 2010 Haiti earthquake or the 2004 Indian Ocean tsunami, these disasters have time and time again wrecked large populations and national infrastructures. While recognizing that improved rescue, evacuation, and disease control are crucial to reducing the effects of natural disasters, in the final analysis, poverty remains the main risk factor determining the long-term impact of natural hazards. Furthermore, natural disasters have themselves a tremendous impact on the poorest of the poor, who are often ill-prepared to deal with natural hazards and for whom a hurricane, an earthquake, or a drought can mean a permanent submersion in poverty. The Economic Impacts of Natural Disasters focuses on these concerns for poverty and vulnerability. Written by a collection of esteemed scholars in disaster management and sustainable development, the report provides an overview of the general trends in natural disasters and their effects by focusing on a critical analysis of different methodologies used to assess the economic impact of natural disasters. Economic Impacts presents six national case studies (Bangladesh, Vietnam, India, Nicaragua, Japan and the Netherlands) and shows how household surveys and country-level macroeconomic data can analyze and quantify the economic impact of disasters. The researchers within Economic Impacts have created path-breaking work and have opened new avenues for thinking and debate to push forward the frontiers of knowledge on economics of natural disasters. "A great report and an important addition to the literature about the economics of disasters and the cost-effectiveness of prevention, mitigation and adaption, including a good number of interesting and relevant applications from developed and devloping countries."—Javier E. Baez, Independent Evaluation Group, The World Bank Readership: Undergraduate/graduate students and scholars of the economics of natural disasters, disaster management, sustainable development, environmental economics, environmental risk management, and environmental policy.
