Resilience to Climate-Induced Disasters and Its Overall Relationship to Well-Being in Southern Africa: A Mixed-Methods Systematic Review.

The available literature suggests that natural disasters, especially droughts and floods, were occurring in southern Africa in the early 1900s. However, their frequency and intensity increased during the 1980s. The aim of this systematic review was to assess the relationship between resilience to droughts and people's well-being in southern Africa. A combination of keywords was used to search the following 13 electronic bibliographic databases: Africa Journal Online (AJOL), MEDLINE, Academic Search Complete, Environment Complete, Humanities International Complete, Psychology and Behavioral Sciences Collection, PsycINFO, Embase, Scopus, Web of Science, Applied Social Science Index and Abstracts, ProQuest Central, and CINAHL. Relevant websites were also searched and potential studies for inclusion were downloaded in an EndNote database and screened for eligibility using pre-determined criteria. Quality assessment of the studies was undertaken using the Joana Briggs Qualitative Assessment and Review Instrument, the National Institutes of Health (NIH) checklist, and the Authority, Accuracy, Coverage, Objectivity, Date, Significance (AACODS) checklist. Resilience and well-being scales used in the studies for inclusion were also assessed using pre-defined criteria. Nineteen studies met the inclusion criteria. Poverty alleviation policies were important in strengthening resilience and well-being outcomes. Resilience and well-being were connected by old age, gender, race, adaptive farming and livelihoods diversification, security, and knowledgeability. Resilience and well-being outcomes were advanced by the synergistic effect of household, community and governance level capacities encapsulated in knowledgeability. This systematic review is critical to improving southern Africa context-specific resilience, and well-being policies and interventions.

Major Natural Disasters in China, 1985-2014: Occurrence and Damages.

This study aimed to describe the characteristics of natural disasters and associated losses from 1985 to 2014. The Mann-Kendall method was used to detect any long-term trends and abrupt changes. Hotspot analysis was conducted to detect the spatial clusters of disasters. We found an increasing trend in the occurrence of integrated natural disasters (tau = 0.594, p < 0.001), particularly for floods (tau = 0.507, p < 0.001), landslides (tau = 0.365, p = 0.009) and storms (tau = 0.289, p = 0.032). Besides, there was an abrupt increase of natural disasters in 1998-2000. Hotspots of droughts, floods, landslides and storms were identified in central, southern, southwest and southeast areas of China, respectively. Annual deaths from integrated natural disasters were decreasing (tau = -0.237, p = 0.068) at about 32 persons/year, decreasing at 17 persons/year for floods (tau = -0.154, p = 0.239), and decreasing at approximately 12 persons/year for storms (tau = -0.338, p = 0.009). No significant trend was detected in inflation-adjusted damages while a declining trend was detected in the ratio of year damage against GDP (gross domestic product). In conclusion, there has been an increasing trend in occurrence of natural disasters in China with the absence of an increase in life and economic losses. Despite the progress in the disaster adaption, there will be great challenges in disaster control for China in the future.

What Occupational Health Needs Arise in Workplaces Following Disasters? A Joint Analysis of Eight Cases of Disaster in Japan.

OBJECTIVE: To identify occupational health needs arising after disasters. METHODS: Using semistructured interviews with expert informants, we jointly analyzed the needs arising in eight disaster cases that threatened the lives or health of workers in Japan. RESULTS: Various types of health issues occurred in a wide range of employees. In total, we identified 100 needs in six phases after disasters and classified them across nine categories of worker characteristics. The proportion of health needs on the list that were applicable in each case varied from 13% to 49%. More needs arose when the companies were responsible for the disaster and when employee lives were lost. We also assessed the list as fairly comprehensive. CONCLUSIONS: The list developed in this study is expected to be effective for anticipating occupational health needs after disasters.

Disaster Metrics: Evaluation of de Boer's Disaster Severity Scale (DSS) Applied to Earthquakes.

INTRODUCTION: Quantitative measurement of the medical severity following multiple-casualty events (MCEs) is an important goal in disaster medicine. In 1990, de Boer proposed a 13-point, 7-parameter scale called the Disaster Severity Scale (DSS). Parameters include cause, duration, radius, number of casualties, nature of injuries, rescue time, and effect on surrounding community. Hypothesis This study aimed to examine the reliability and dimensionality (number of salient themes) of de Boer's DSS scale through its application to 144 discrete earthquake events. METHODS: A search for earthquake events was conducted via National Oceanic and Atmospheric Administration (NOAA) and US Geological Survey (USGS) databases. Two experts in the field of disaster medicine independently reviewed and assigned scores for parameters that had no data readily available (nature of injuries, rescue time, and effect on surrounding community), and differences were reconciled via consensus. Principle Component Analysis was performed using SPSS Statistics for Windows Version 22.0 (IBM Corp; Armonk, New York USA) to evaluate the reliability and dimensionality of the DSS. RESULTS: A total of 144 individual earthquakes from 2003 through 2013 were identified and scored. Of 13 points possible, the mean score was 6.04, the mode = 5, minimum = 4, maximum = 11, and standard deviation = 2.23. Three parameters in the DSS had zero variance (ie, the parameter received the same score in all 144 earthquakes). Because of the zero contribution to variance, these three parameters (cause, duration, and radius) were removed to run the statistical analysis. Cronbach's alpha score, a coefficient of internal consistency, for the remaining four parameters was found to be robust at 0.89. Principle Component Analysis showed uni-dimensional characteristics with only one component having an eigenvalue greater than one at 3.17. The 4-parameter DSS, however, suffered from restriction of scoring range on both parameter and scale levels. CONCLUSION: Jan de Boer's DSS in its 7-parameter format fails to hold statistically in a dataset of 144 earthquakes subjected to analysis. A modified 4-parameter scale was found to quantitatively assess medical severity more directly, but remains flawed due to range restriction on both individual parameter and scale levels. Further research is needed in the field of disaster metrics to develop a scale that is reliable in its complete set of parameters, capable of better fine discrimination, and uni-dimensional in measurement of the medical severity of MCEs.

Injuries and illnesses among American Red Cross responders-United States, 2008-2012.

OBJECTIVE: Occupational injury and illness rates for volunteer responders have not been well documented. We analyzed data specific to volunteers from the American Red Cross (ARC). METHODS: Data collected by the ARC between 2008 and 2012 were analyzed to identify disaster factors associated with responder injuries and illnesses. We focused on disaster-relief operation (DRO) level (indicating operational costs, ranging from 3 [lower] to 5+ [higher]); disaster type; region; and year. We calculated injury and illness rates and estimated rate ratios (RR) with 95% CI, using negative binomial regression. Also, we analyzed a total of 113 disasters. RESULTS: Hurricanes had the highest rates of injuries (14/1000 responders) and illnesses (18/1000 responders). In the adjusted model for injuries, RRs were higher for DRO levels 4 (3.6 [CI, 2.0-6.7]) and 5+ (4.9 [CI, 2.2-11.0]) than for level 3. In the adjusted model for illnesses, RRs also were higher for DRO levels 4 (4.4 [CI, 2.6-7.3]) and 5+ (8.6 [CI, 4.1-17.7]) than for level 3. CONCLUSIONS: Higher DRO levels were a significant predictor of greater rates of occupational injuries and illnesses. Careful selection of responders, including volunteers, has been warranted for deployments to such disasters. (Disaster Med Public Health Preparedness. 2014;0:1-7).

Historical, observed, and modeled wildfire severity in montane forests of the Colorado Front Range.

Large recent fires in the western U.S. have contributed to a perception that fire exclusion has caused an unprecedented occurrence of uncharacteristically severe fires, particularly in lower elevation dry pine forests. In the absence of long-term fire severity records, it is unknown how short-term trends compare to fire severity prior to 20th century fire exclusion. This study compares historical (i.e. pre-1920) fire severity with observed modern fire severity and modeled potential fire behavior across 564,413 ha of montane forests of the Colorado Front Range. We used forest structure and tree-ring fire history to characterize fire severity at 232 sites and then modeled historical fire-severity across the entire study area using biophysical variables. Eighteen (7.8%) sites were characterized by low-severity fires and 214 (92.2%) by mixed-severity fires (i.e. including moderate- or high-severity fires). Difference in area of historical versus observed low-severity fire within nine recent (post-1999) large fire perimeters was greatest in lower montane forests. Only 16% of the study area recorded a shift from historical low severity to a higher potential for crown fire today. An historical fire regime of more frequent and low-severity fires at low elevations (<2260 m) supports a convergence of management goals of ecological restoration and fire hazard mitigation in those habitats. In contrast, at higher elevations mixed-severity fires were predominant historically and continue to be so today. Thinning treatments at higher elevations of the montane zone will not return the fire regime to an historic low-severity regime, and are of questionable effectiveness in preventing severe wildfires. Based on present-day fuels, predicted fire behavior under extreme fire weather continues to indicate a mixed-severity fire regime throughout most of the montane forest zone. Recent large wildfires in the Front Range are not fundamentally different from similar events that occurred historically under extreme weather conditions.

Entropy-functional-based online adaptive decision fusion framework with application to wildfire detection in video.

In this paper, an entropy-functional-based online adaptive decision fusion (EADF) framework is developed for image analysis and computer vision applications. In this framework, it is assumed that the compound algorithm consists of several subalgorithms, each of which yields its own decision as a real number centered around zero, representing the confidence level of that particular subalgorithm. Decision values are linearly combined with weights that are updated online according to an active fusion method based on performing entropic projections onto convex sets describing subalgorithms. It is assumed that there is an oracle, who is usually a human operator, providing feedback to the decision fusion method. A video-based wildfire detection system was developed to evaluate the performance of the decision fusion algorithm. In this case, image data arrive sequentially, and the oracle is the security guard of the forest lookout tower, verifying the decision of the combined algorithm. The simulation results are presented.

An analysis of seismic risk from a tourism point of view.

Global awareness of natural calamities increased after the destructive Indian Ocean tsunami of December 2004, largely because many foreigners lost their lives, especially in Thailand. This paper explores how best to communicate the seismic risk posed by different travel destinations to crisis management personnel in tourists' home countries. The analysis of seismic risk should be straightforward enough for non-specialists, yet powerful enough to identify the travel destinations that are most at risk. The output for each location is a point in 3D space composed of the natural and built-up environment and local tourism. The tourism-specific factors can be tailored according to the tourists' nationality. The necessary information can be collected from various directories and statistics, much of it available over the Internet. The output helps to illustrate the overall seismic risk conditions of different travel destinations, allows for comparison across destinations, and identifies the places that are most at risk.

Forensic odontology, part 2. Major disasters.

We have only to look back over the last 12 months to realise that time and time again, an incident occurs where there are mass fatalities. These incidents have instant and long-lasting impact on families, communities and sometimes whole countries. The aim of this paper is to emphasise the need for an efficient and sensitive response to assist in the identification of victims of such incidents and the necessity for trained team responses. Many countries now have Disaster Victim Identification (DVI) teams that are multi-disciplinary, and plans and protocols in place in readiness. The paper can only hope to give a brief overview of the disaster situation for the reader: whole books have been written on this topic. The forensic odontologist has a major role in disaster incidents when there are accurate and available antemortem dental records.

The nature of the public health emergency preparedness literature 2000-2008: a quantitative analysis.

OBJECTIVES: This study characterizes the nature, size, and knowledge gaps of the public health emergency preparedness (PHEP) literature. METHODS: Systematic review of PHEP articles published in 10 relevant journals from 2000 through 2008 was conducted. An inclusion process and coding sheet was developed; articles were coded on the basis of abstract content for variables, including type of methods used, disaster type, disaster life cycle focus, and article focal point. Descriptive analyses and cross-tabulations were used to characterize the nature of the literature. RESULTS: The sample included 823 articles; human-made disasters (39.4%, n = 323) were the most common, followed by natural disasters (30.7%, n = 252). The preparedness life cycle phase represented 60.5% (n = 497) of articles. Overall, 67.8% (n = 558) of articles were nonempirical; however, this differed by disaster type and focal point. DISCUSSION: Most of the PHEP literature is based on commentaries and other nonempirical articles forcing policymakers and practitioners to rely on weak anecdotal evidence or opinions for decision making. Several literature gaps are identified and presented as areas for future research. More research utilizing diverse methods and data sets is needed to build a strong evidence-based knowledge base on many PHEP topics.

Defending against disasters: global public health emergencies and opportunities for collaboration and action.

The World Health Organization project on the Global Burden of Disease quantifies the main causes of premature death and disability. Changing patterns of physical activity, diet, and alcohol and tobacco consumption are producing a growing burden of noncommunicable disease in low-and middle-income countries. This article focuses on a different group of health risks: major health emergencies that do not respect national borders and have an impact on health and the determinants of health such as housing, access to food and water, and other life essentials. Health emergencies, including accidents and natural events, are described, and data on disasters in the Middle East are presented. Disaster response is contrasted with disaster prevention, and disaster risk reduction is discussed in the context of vulnerability, climate change, and sustainable development. Finally, the international policy context of disaster risk reduction is discussed along with opportunities for multidisciplinary and multiinstitutional collaboration and research.

Modelo de respuesta inmediata ante grandes emergencias para la atención sanitaria en entornos de dispersión geográfica / No disponible

Las situaciones de accidentes con múltiples víctimas, grandes emergencias y catástrofes suponen un reto para los servicios de emergencia de cualquier comunidad. Los entornos de gran extensión geográfica y dispersión de población suponen un desafío añadido a la gestión eficiente de los recursos. Con el fin de dar solución a estas situaciones se plantea un sistema de respuesta sanitario que se basa fundamentalmente en tres puntos: -Distribución estratégica de recursos, añadidos a los habituales. -Determinación de responsables y asignación de funciones en una respuesta escalonada. -Formación inicial y continuada de los profesionales. Todo ello adaptado al Plan Territorial de Emergencias correspondiente. Se trata de evitar que estas situaciones, por inesperadas, sean imprevistas.(AU)

Accidents with multiple victims, great emergencies and catastrophes suppose a challenge for the emergency services of any community. In the great geographic extension communities, it supposes an added challenge. With the purpose of giving solution to these situations, a sanitary system of answer has been developed that is based fundamentally on three points: -Strategic distribution of special resources, -Determination of people in responsibility level and allocation of functions in a staggered answer -Initial formation and continued of the professionals. Everything is adapted to the Territorial Plan of Emergencies. It’s necessary to prevent unexpected situations(AU)

Los desastres como fenómenos diferentes a la guerra / Disasters like different war phenomen

Existen diferencias sustanciales entre la guerra y los desastres. A pesar de la amplia diversidad de conceptos de desastres, múltiples autores incluyen a la guerra dentro de los desastres. De manera similar ocurre con la clasificación de estos, basados en el supuesto de que las consecuencias para las comunidades humanas que la sufren son equivalentes. Se exponen una serie de aspectos que hacen diferente a las guerras y los desastres. Entre ellos se se±ala la finalidad de la guerra de causar el mayor daño posible a una determinada población o comunidad, y las diferencias del impacto sobre la salud física y mental, donde en la guerra estß agravado por los obstáculos que las partes contendientes imponen para realizar las labores de atención a la salud. En esta además se crean las condiciones propicias para extender la violencia y perpetuarla. Se concluye que las diferencias entre la guerra y los desastres en relación con las causas y las consecuencias para la salud resultan mayores que las similitudes que ambos fenómenos presentan, por lo que son 2 situaciones que hay que estudiarlas por separado para no propiciar errores y confusión(AU)

There are significant differences between the war and the disasters. Despite the broad diversity of criteria son disasters, many authors include the war within the category of disaster. The same occurs with its classification, based on supposing that consequences for human communities suffering it be equivalent. We present a series of features to distinguishing between a war and a disaster. Among them are included the purpose of a war that is to cause the greater damage possible in a determined population or community, and the impact differences on physical and mental health, where in the war is aggravated by obstacles imposed by the contending parts to make the health care tasks. In war the appropriate conditions to extend violence and to perpetuate it are created. We conclude that differences between a war and a disaster in relation with causes and consequences for health are greater than similarities presented by both phenomena, being two situations that must to be separately studied to avoid errors and confusion(AU)
