TL;DR: In this paper, the authors developed an assessment model for social resilience by measuring the heterogeneity of local indicators that are related to disaster risk, and proposed a new spatial disaster assessment model that can be used for disaster management at the local levels.
Abstract: Since avoiding the occurrence of natural disasters is difficult, building ‘resilient cities’ is gaining more attention as a common objective within urban communities. By enhancing community resilience, it is possible to minimize the direct and indirect losses from disasters. However, current studies have focused more on physical aspects, despite the fact that social aspects may have a closer relation to the inhabitants. The objective of this paper is to develop an assessment model for social resilience by measuring the heterogeneity of local indicators that are related to disaster risk. Firstly, variables were selected by investigating previous assessment models with statistical verification. Secondly, spatial heterogeneity was analyzed using the Geographically Weighted Regression (GWR) method. A case study was then undertaken on a flood-prone area in the metropolitan city, Seoul, South Korea. Based on the findings, the paper proposes a new spatial disaster assessment model that can be used for disaster management at the local levels.

TL;DR: According to the Annual Disaster Statistical Review of 2012, the average number of naturally-triggered disasters occurring within a period of 1 year is about 300 events, in which over 100,000 people are killed as a consequence of their impacts.
Abstract: According to the Annual Disaster Statistical Review of 2012, the average number ofnaturally-triggered disasters occurring within a period of 1 year is about 300 events, inwhich over 100,000 people are killed as a consequence of their impacts. The statisticsofdisastersshedlightonimportanttrendsarising,ofwhichthetwomostsalientarethatdeveloping and emerging economies suffer the most from human losses, and that thecosts of natural disasters are escalating over time. In 2012 the Hurricane Sandy, one ofthe most ever expensive natural disasters in the United States, created damages forapproximately US$ 50.0 billion (Guha-Sapir et al. 2013). Both natural and man-madedisasters may have various spatial effects (from local to global scales) which reverber-ate for hours and even years when the damages affect the backbone of a system. Thusinvestigating these phenomena represent a complex but compelling issue. In the aim topredict and minimise the substantial economic losses generated by disruptive events,the attention of scholars, practitioners and policy makers is nowadays turning squarelytoward such concepts as resilience, vulnerability, robustness, and reliability of econom-ic spatial systems (Rose 2009).In essence, resilience refers to the capacity of a network: a) to retain its organiza-tional structure following the perturbation of some state variable from a given value; b)to adapt itself to new states; thus evolution is formed by the switch of these resilientnetworks from one equilibrium state to another. These definitions stem from ecology(for a review, Reggiani et al. 2002). The main question is then how fast and efficientlythe network returns/shifts to steady states. Vulnerability research stems, by contrast,from hazard studies in geophysical/social sciences and in political economy/ecology.

TL;DR: Wang et al. as discussed by the authors presented a methodology for dynamic risk analysis and assessment of drought disaster to maize production in the northwest of Liaoning Province based on remote sensing data and GIS from the viewpoints of climatology, geography and disaster science.
Abstract: The traditional studies on drought disaster risk were based on the ground point data, which were unable to realize the continuity of space and the timeliness It is shown that the monitoring and evaluation precision on drought were reduced significantly However, remote sensing data in adequate spatial and temporal resolution can overcome these limitations It can better monitor the crop in large area dynamically This study presents a methodology for dynamic risk analysis and assessment of drought disaster to maize production in the northwest of Liaoning Province based on remote sensing data and GIS from the viewpoints of climatology, geography and disaster science The model of dynamic risk assessment of drought disaster was established based on risk formation theory of natural disaster, and the expression of risk by integrating data came from sky, ground and space The risk indexes were divided into four classes by data mining method, and the grade maps of drought disaster risk were drawn by GIS It is shown that the spatial and temporal risk distributions of maize at each growth stage changed over time The model has been verified against reduction in maize yield caused by drought It demonstrated the reasonability, feasibility and reliability of the model and the methodology The dynamic risk assessment of regional drought disaster for maize can be used as a tool, which can timely monitor the status (the possibility and extent of drought) and trends of regional drought disaster The results obtained in this study can provide the latest information of regional drought disaster and the decision-making basis of disaster prevention and mitigation for government management and farmers

TL;DR: In this article, the authors introduce readers to empirical research on the psychology of religion/ spirituality and disasters as well as to introduce a framework for spiritually oriented disaster psychology, which is used in this paper.
Abstract: According to Ronan and Johnston (2005) the number of people who will experience a disaster will double by 2050 from one billion people to two billion people. Since 1985 there has been an almost 400% increase in global natural disasters (Center for Research on the Epidemiology of Disasters, 2007). Researchers managing the global terrorism database report a similar increase in terrorist events over the last decade, with almost 5,000 events annually. Some of the worst disasters, such as Hurricane Katrina, Haiti Earthquake, Japan Tsunami, and Philippines Typhoon occurred in the past decade alone. Disasters are becoming more complex, with primary disasters (e.g., earthquake) often triggering secondary disasters (e.g., nuclear meltdown). Research shows that disasters often leave a significant psychological and spiritual “footprint” on affected communities. Thus, the purpose of this article is to introduce readers to empirical research on the psychology of religion/ spirituality and disasters as well as to introduce a framework for spiritually oriented disaster psychology.

TL;DR: This work states that the world's 52 small island developing states are recognized as a collective of countries that experience disproportionate challenges for sustainable development related to their geography, small size, and physical isolation.
Abstract: In contrast to continental nations, the world's 52 small island developing states (SIDS) are recognized as a collective of countries that experience disproportionate challenges for sustainable development related to their geography, small size, and physical isolation. These same states also face elevated risks for disaster incidence and consequences particularly in the realms of climate change, sea level rise, natural disasters (tropical cyclones, earthquakes, tsunamis, volcanoes), and marine hazardous materials spills. Cyclone Winston's direct impact on Fiji in 2016 and Cyclone Pam's landfall over Vanuatu in 2015 provide case examples illustrating the special vulnerabilities of the SIDS.
