Good response facilitates recovery and development. Africa’s hazards and vulnerabilities have been the targets of 30 years of development: their persistence testifies to as many failures. Today, ever-increasing resources are spent for disaster relief, at the expense of development. But only development can reduce vulnerabilities, and the hazards arising from the socio-economic structure. 6 THE DISASTER-DEVELOPMENT CONTINUUM Disasters and crisis (“emergencies”) are not aberrant phenomena. They are reflections of the ways societies structure themselves and allocate their resources. (R.

  • Disaster Risk Reduction in the United Nations
    Disaster Risk Reduction in the United Nations 2009 Roles, mandates and areas of work of key United Nations entities Disaster Risk Reduction in the United Nations 2009 Roles, mandates and areas of work of key United Nations entities Disaster Risk Reduction in the United Nations Introduction The “Hyogo Framework for Action 2005-2015: Building the Resilience for Nations and Communities to Disasters” (HFA) calls upon the United Nations system and other international organizations to undertake concrete tasks within their mandates, priorities and resources. The HFA encourages all organizations to incorporate disaster risk considerations systematically in their own strategies, programmes, advocacy, budgets and internal organization and to participate in International Strategy for Disaster Reduction (ISDR) initiatives. It emphasises strengthening of the United Nations system to assist disaster-prone developing countries with disaster risk reduction initiatives and to support States’ own efforts with technical assistance and capacity development. Four years on from the World Conference on Disaster Reduction in Kobe, Japan, and with the mid-term review of the Hyogo Framework for Action approaching in 2010, it is timely to take a closer look to what extent the existing mandates and policies of the United Nations entities align with the HFA and what stage the United Nations has reached in mainstreaming disaster risk reduction (often referred to as DRR) into its work. While this compilation is not exhaustive, it shows an impressive portfolio of services and programmes of the United Nations and the World Bank in support of disaster risk reduction. It brings together the core set of ISDR system partners, the Inter-Agency Group, also listing disaster risk reduction networks and national counterparts, responsible for various areas of work at the country level.

  • Evidence from Sales of Emergency Supplies Before and After Hurricanes†‡
    Disaster preparedness and disaster response: Evidence from †‡ sales of emergency supplies before and after hurricanes Timothy K.M. Beatty§, Jay P. Shimshack**, Richard J. Volpe†† May 2018 ABSTRACT Government information warns households to acquire emergency supplies as hurricanes threaten and directs households to stay off roads after hurricanes make landfall. Do households follow this advice? If so, who, when, and how much? We provide novel evidence. We combine forecast and landfall data for U.S. hurricanes between 2002 and 2012 with extensive scanner data on sales of bottled water, batteries, and flashlights. We find that sales of emergency supplies increase when a location is threatened by hurricane. The bulk of the sales increases occur immediately prior to forecasted landfall. The average increase in sales after landfall is large and statistically significant. Observed emergency preparation as hurricanes threaten is moderately higher in coastal, wealthier, and whiter areas. Ex-post emergency responses after hurricanes make landfall are sharply higher in African American, lower income, and less educated areas. Our results suggest that households do not follow government advice.

  • Challenges and Considerations in Disaster Research
    SAMHSA Disaster Technical Assistance Center Supplemental Research Bulletin: Challenges and Considerations in Disaster Research January 2016 ∙ INTRODUCTION Disaster research allows professionals in the field to advance existing preparedness, response, and recovery practices. It is important to study the impact of disasters on behavioral health to identify the emergence of psychopathology and to develop mental health interventions to prevent or mitigate the traumatic effect. However, this specific type of research comes with many ethical and methodological challenges that may dissuade or hinder its execution, such as funding and timing constraints, environmental concerns, risk for disaster survivors, and the public perception of conducting research during a time of distress (Knack et al., 2006). The primary dilemma faced by researchers is safely balancing the pursuit of answers to their questions with the serious and immediate needs of survivors (Benight et al., 2007). This issue of SAMHSA Disaster Technical Assistance Center’s Supplemental Research Bulletin, “Challenges and Considerations in Disaster Research,” addresses the ethical and operational concerns in research design, participant recruitment, data collection, and data interpretation during disaster research. The purpose of this issue is for researchers to learn about and anticipate procedural challenges that can only be overcome by prior planning, including having a research team properly trained in and prepared for the unique aspects of disaster research (Lavin et al., 2012). The following challenges and considerations will be discussed in this issue: 1. Risk-benefit analysis 2. Funding 3. Institutional Review Board approval 4. Participant recruitment 5. Informed consent 6. Emotional distress of participants 7. Participant tracking 8. Researcher safety and distress 9.

  • FEMA Developing and Maintaining Emergency Operations Plans
    Developing and Maintaining Emergency Operations Plans Comprehensive Preparedness Guide (CPG) 101 Version 2.0 November 2010 I am pleased to announce the release of Version 2.0 of Comprehensive Preparedness Guide 101: Developing and Maintaining Emergency Operations Plans. Comprehensive Preparedness Guide (CPG) 101 provides guidance for developing emergency operations plans. It promotes a common understanding of the fundamentals of risk-informed planning and decision making to help planners examine a hazard or threat and produce integrated, coordinated, and synchronized plans. The goal of CPG 101 is to assist in making the planning process routine across all phases of emergency management and for all homeland security mission areas. This Guide helps planners at all levels of government in their efforts to develop and maintain viable, all-hazards, all-threats emergency plans. Based on input from state, territorial, tribal, and local officials from across the United States, this update of CPG 101 expands on the fundamentals contained in the first version. With this edition, greater emphasis is placed on representing and engaging the whole community—to include those with access and functional needs, children, and those with household pets and service animals. Residents and all sectors of the community have a critical role and shared responsibility to take appropriate actions to protect themselves, their families and organizations, and their properties. Planning that engages and includes the whole community serves as the focal point for building a collaborative and resilient community. CPG 101 is the foundation for state, territorial, tribal, and local emergency planning in the United States. Planners in other disciplines, organizations, and the private sector, as well as other levels of government, may find this Guide useful in the development of their emergency operations plans.

  • Haiti Earthquake: Crisis and Response
    Haiti Earthquake: Crisis and Response Rhoda Margesson Specialist in International Humanitarian Policy Maureen Taft-Morales Specialist in Latin American Affairs February 2, 2010 Congressional Research Service 7-5700 www.crs.gov R41023 CRS Report for Congress Prepared for Members and Committees of Congress Haiti Earthquake: Crisis and Response Summary The largest earthquake ever recorded in Haiti devastated parts of the country, including the capital, on January 12, 2010. The quake, centered about 15 miles southwest of Port-au-Prince, had a magnitude of 7.0. A series of strong aftershocks have followed. The damage is severe and catastrophic. It is estimated that 3 million people, approximately one third of the overall population, have been affected by the earthquake. The Government of Haiti is reporting an estimated 112,000 deaths and 194,000 injured. In the immediate wake of the earthquake, President Preval described conditions in his country as “unimaginable,” and appealed for international assistance. As immediate needs are met and the humanitarian relief operation continues, the government is struggling to restore the institutions needed for it to function, ensure political stability, and address long-term reconstruction and development planning. Prior to the earthquake, the international community was providing extensive development and humanitarian assistance to Haiti. With that assistance, the Haitian government had made significant progress in recent years in many areas of its development strategy. The destruction of Haiti’s nascent infrastructure and other extensive damage caused by the earthquake will set back Haiti’s development significantly. Haiti’s long-term development plans will need to be revised. The sheer scale of the relief effort in Haiti has brought together tremendous capacity and willingness to help.

  • Adversus Paganos: Disaster, Dragons, and Episcopal Authority in Gregory of Tours
    Adversus paganos: Disaster, Dragons, and Episcopal Authority in Gregory of Tours David J. Patterson Comitatus: A Journal of Medieval and Renaissance Studies, Volume 44, 2013, pp. 1-28 (Article) Published by Center for Medieval and Renaissance Studies, UCLA DOI: 10.1353/cjm.2013.0000 For additional information about this article http://muse.jhu.edu/journals/cjm/summary/v044/44.patterson.html Access provided by University of British Columbia Library (29 Aug 2013 02:49 GMT) ADVERSUS PAGANOS: DISASTER, DRAGONS, AND EPISCOPAL AUTHORITY IN GREGORY OF TOURS David J. Patterson* Abstract: In 589 a great flood of the Tiber sent a torrent of water rushing through Rome. According to Gregory of Tours, the floodwaters carried some remarkable detritus: several dying serpents and, perhaps most strikingly, the corpse of a dragon. The flooding was soon followed by plague and the death of a pope. This remarkable chain of events leaves us with puzzling questions: What significance would Gregory have located in such a narrative? For a modern reader, the account (apart from its dragon) reads like a descrip- tion of a natural disaster. Yet how did people in the early Middle Ages themselves per- ceive such events? This article argues that, in making sense of the disasters at Rome in 589, Gregory revealed something of his historical consciousness: drawing on both bibli- cal imagery and pagan historiography, Gregory struggled to identify appropriate objects of both blame and succor in the wake of calamity. Keywords: plague, natural disaster, Gregory of Tours, Gregory the Great, Asclepius, pagan survivals, dragon, serpent, sixth century, Rome. In 589, a great flood of the Tiber River sent a torrent of water rushing through the city of Rome.
