TL;DR: Methods for valuation and benefit-cost analysis based on concepts from risk analysis and management are provided that meet a set of requirements with clear relationships to the metrics of the relevant abstract notions of reliability and risk.
Abstract: The United Nations Office for Disaster Risk Reduction reported that the 2011 natural disasters, including the earthquake and tsunami that struck Japan, resulted in $366 billion in direct damages and 29,782 fatalities worldwide. Storms and floods accounted for up to 70% of the 302 natural disasters worldwide in 2011, with earthquakes producing the greatest number of fatalities. Average annual losses in the United States amount to about $55 billion. Enhancing community and system resilience could lead to massive savings through risk reduction and expeditious recovery. The rational management of such reduction and recovery is facilitated by an appropriate definition of resilience and associated metrics. In this article, a resilience definition is provided that meets a set of requirements with clear relationships to the metrics of the relevant abstract notions of reliability and risk. Those metrics also meet logically consistent requirements drawn from measure theory, and provide a sound basis for the development of effective decision-making tools for multihazard environments. Improving the resiliency of a system to meet target levels requires the examination of system enhancement alternatives in economic terms, within a decision-making framework. Relevant decision analysis methods would typically require the examination of resilience based on its valuation by society at large. The article provides methods for valuation and benefit-cost analysis based on concepts from risk analysis and management.

TL;DR: The authors examined the learning process that economic agents use to update their expectation of an uncertain and infrequently observed event and found that insurance take-up is most consistent with a Bayesian learning model that allows for forgetting or incomplete information about past floods.
Abstract: I examine the learning process that economic agents use to update their expectation of an uncertain and infrequently observed event. I use a new nation-wide panel dataset of large regional floods and flood insurance policies to show that insurance take-up spikes the year after a flood and then steadily declines to baseline. Residents in nonflooded communities in the same television media market increase take-up at one-third the rate of flooded communities. I find that insurance take-up is most consistent with a Bayesian learning model that allows for forgetting or incomplete information about past floods. (JEL D12, D83, D84, G22, Q54)

TL;DR: A model of human behavior is developed that takes into account social relationship, intensity of disaster, damage level, government appointed shelters, news reporting, large population flow and etc. for accurately predicting human emergency behavior and their mobility following large-scale disaster.
Abstract: The frequency and intensity of natural disasters has significantly increased over the past decades and this trend is predicted to continue. Facing these possible and unexpected disasters, accurately predicting human emergency behavior and their mobility will become the critical issue for planning effective humanitarian relief, disaster management, and long-term societal reconstruction. In this paper, we build up a large human mobility database (GPS records of 1.6 million users over one year) and several different datasets to capture and analyze human emergency behavior and their mobility following the Great East Japan Earthquake and Fukushima nuclear accident. Based on our empirical analysis through these data, we find that human behavior and their mobility following large-scale disaster sometimes correlate with their mobility patterns during normal times, and are also highly impacted by their social relationship, intensity of disaster, damage level, government appointed shelters, news reporting, large population flow and etc. On the basis of these findings, we develop a model of human behavior that takes into account these factors for accurately predicting human emergency behavior and their mobility following large-scale disaster. The experimental results and validations demonstrate the efficiency of our behavior model, and suggest that human behavior and their movements during disasters may be significantly more predictable than previously thought.

TL;DR: In this article, the authors summarized the lessons learned from the 2011 Great East Japan Earthquake and Tsunami and provided guidance to other disaster-prone countries for mainstreaming disaster risk management in their development policies.
Abstract: On March 11, 2011, an earthquake of magnitude 9.0 occurred in the Pacific Ocean off the coast of Japan's Tohoku region. The Great East Japan Earthquake was the first disaster ever recorded that included an earthquake, a tsunami, a nuclear power plant accident, a power supply failure, and a large-scale disruption of supply chains. This report consolidates the set of 36 Knowledge Notes, research results of the joint study undertaken by the Government of Japan and the World Bank. It summarizes the lessons learned from the Great East Japan Earthquake and Tsunami and provides guidance to other disaster-prone countries for mainstreaming disaster risk management in their development policies. It is clear that financial resources alone are not sufficient to deal with disasters and to spur development. Technical assistance and capacity building are equally important. In Japan's case, the project learned how communities can play a critical role in preparing for and coping with natural disasters. Communities can help prevent damage from spreading, maintain social order, and provide support to the vulnerable. Only through technical cooperation can such know-how be passed on to other countries and be adapted to their local circumstances. The chapters that make up the main body of this report are built around the disciplines employed in the traditional disaster risk management cycle. Grouped into seven thematic clusters that track that cycle, the chapters treat structural measures (part 1) and nonstructural measures (part 2) as preventive options. Also covered is the emergency responses put in place after March 11 (part 3) and described the planning behind the reconstruction process (part 4). The handling of risk assessment and communication before and after the disaster are the subject of part 5. Part 6 deals with risk financing, insurance, and fiscal and financial management; part 7 with the progress of recovery and relocation.

TL;DR: In this paper, a new multi-objective mixed-integer linear programming model is developed for preparation planning phase of disaster management, inspired from a real case study of an urban district in Iran, which considers both humanitarian and cost-based objectives in a goal-programming approach.
Abstract: Thousands of victims and millions of affected people are consequences of natural disasters, every year. Therefore, it is essential to prepare a proper response program that considers early activities of disaster management. In urban areas, local organizations and municipal authorities are responsible for disaster-related operations such as providing emergency shelters, proper equipment, and relief supplies in order to reduce sufferings of survivors. In this paper, a new multi-objective mixed-integer linear programming model is developed for preparation planning phase of disaster management. The proposed model is inspired from a real case study of an urban district in Iran, which considers both humanitarian- and cost-based objectives in a goal-programming approach. Proactive damage estimation result of Risk Assessment tool for Diagnosis of Urban Areas against Seismic Disaster software is used as an input in order to allocate affected people to local emergency management facilities that should be established. The location allocation model is solved for both current municipal subregional zoning and a virtual zoning approach that creates auxiliary cells. Mathematical results show that the second approach can reduce logistic costs and increase total coverage simultaneously. In other words, using virtual zones would help the authorities create a better collaboration between neighboring local areas and as a result, efficiency of the decisions improves.

TL;DR: In this paper, the authors outline the criteria and definitions relating to how global and multi-peril databases are operated, and the efforts being made to ensure consistent and internationally recognised standards of data management.
Abstract: Hundreds of natural catastrophes occur worldwide every year—there were 780 loss events per year on average over the last 10 years. Since 1980, these disasters have claimed over two million lives and caused losses worth US$ 3,000 billion. The deadliest disasters were caused by earthquakes: the tsunami following the Sumatra quake (2004) and the Haiti earthquake (2010) claimed more than 220,000 lives each. The Great East Japan Earthquake of 11 March 2011 was the costliest natural disaster of all times, with total losses of US$ 210 billion. Hurricane Katrina, in 2005, was the second costliest disaster, with total losses of US$ 140 billion (in 2010 values). To ensure that high-quality natural disaster analyses can be performed, the data have to be collected, checked and managed with a high degree of expertise and professionality. Scientists, governmental and non-governmental organisations and the finance industry make use of global databases that contain losses attributable to natural catastrophes. At present, there are three global and multi-peril loss databases: NatCatSERVICE (Munich Re), Sigma (Swiss Re) and EM-Dat (Centre for Research on the Epidemiology of Disasters). They are supplemented by numerous databases focusing on national or regional issues, certain hazards and specific sectors. This paper outlines the criteria and definitions relating to how global and multi-peril databases are operated, and the efforts being made to ensure consistent and internationally recognised standards of data management. In addition, it presents the concept and methodology underlying the NatCatSERVICE database, and points out the many challenges associated with data acquisition and data management.

TL;DR: In this article, the authors 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, and they 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.
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.

TL;DR: In this article, the authors developed a framework to assess the resilience of disaster-prone areas in Indonesia towards natural disasters, by establishing an index that is defined as the ratio between preparedness and vulnerability.
Abstract: Most areas in Indonesia are prone to natural disasters, such as earthquakes, tsunami and volcano eruptions. In order to minimize the disaster impacts and shorten the recovery period, the resilience of a disaster-prone area is required to be assessed. This paper aims to develop a framework to assess the resilience of disaster-prone areas in Indonesia towards natural disasters, by establishing an index. In the framework, resilience is defined as the ratio between preparedness and vulnerability. The dimensions for preparedness are social, economic, community capacity, institutional and infrastructure. Similar dimensions applied for the vulnerability with additional dimension of hazard, come up with an index that is scaled from 0 to 1. The framework is applied to assess the resilience of Cilacap regency (in Central Java province) and the city of Padang (in West Sumatra province). The results show that both areas are resilient towards natural disasters, although certain improvements still can be made to further increase the resilience of both areas.

TL;DR: In this paper, a GIS database on disastrous floods and landslides for the period 1865-2010, which is available in http://riskam.ul.pt/disaster/en.
Abstract: In the last century, Portugal was affected by several natural disasters of hydro-geomorphologic origin that often caused high levels of destruction. However, data on past events related to floods and landslides were scattered. The Disaster project aims to bridge the gap on the availability of a consistent and validated hydro-geomorphologic database for Portugal, by creating, disseminating and exploiting a GIS database on disastrous floods and landslides for the period 1865–2010, which is available in http://riskam.ul.pt/disaster/en . Data collection is steered by the concept of disaster used within the Disaster project. Therefore, any hydro-geomorphologic case is stored in the database if the occurrence led to casualties or injuries, and missing, evacuated or homeless people, independently of the number of people affected. The sources of information are 16 national, regional and local newspapers that implied the analysis of 145,344 individual newspapers. The hydro-geomorphologic occurrences were stored in a database containing two major parts: the characteristics of the hydro-geomorphologic case and the corresponding damages. In this work, the main results of the Disaster database are presented. A total of 1,621 disastrous floods and 281 disastrous landslides were recorded and registered in the database. These occurrences were responsible for 1,251 dead people. The obtained results do not support the existence of any exponential increase in events in time, thus contrasting with the picture provided to Portugal by the Emergency Events Database. Floods were more frequent during the period 1936–1967 and occurred mostly from November to February. Landslides were more frequent in the period 1947–1969 and occurred mostly from December to March.

TL;DR: This article conducted a systematic newspaper analysis during a one-year period to explore media framings of the flood, focused on learning as an aspect of resilience in relation to two themes: perceived links between the flood and climate change and perceived roles of government in managing the flood.
Abstract: In the wake of the flood that affected Brisbane, Australia, in January 2011, public attention turned to the causes of the event and lessons for minimizing the impacts of future floods. The news media was an important vehicle for understanding and internalizing the 2011 Brisbane flood. Examining how the flood was framed in the media is, therefore, useful to understand broad public perception of floods. We undertook a systematic newspaper analysis during a one-year period to explore media framings of the flood, focused on learning as an aspect of resilience in relation to two themes: (1) perceived links between the flood and climate change and (2) perceived roles of government in managing the flood. We show that media coverage of the flood reinforces aspects of resilience by acknowledging community spirit, self-reliance and the importance of sharing experiences for learning; articulating the risk of extreme events in a changing climate; and highlighting regional management trade-offs. Much of the discourse is likely to inhibit resilience, however, by casting the flood in terms of blame and political opportunity and paying inadequate attention to longer-term aspects of regional resilience. The limited learning observed to date may highlight a need for other mechanisms and actors to lead learning processes. As policy related to the 2011 Brisbane flood, and extreme events more generally, is influenced by the public discourse, it is important to understand the nuances of communication around these events and the media’s role in reinforcing or changing perceptions.

TL;DR: In this paper, the authors explored women's preparedness, risk and loss, cultural and conditional behaviour, adaptability and recovery capacity from natural disasters in the coastal regions of Bangladesh.
Abstract: Natural disasters are frequent phenomena in the coastal regions of Bangladesh, causing significant damage to the coastal community and environment. The present study was conducted in southern coastal region of Bangladesh with the aim to explore women׳s preparedness, risk and loss, cultural and conditional behaviour, adaptability and recovery capacity from the natural disasters. During disaster a kind of functional disorder gets created where women had to face challenges different from men. Women have to face loss of livelihood opportunities, deprivation from relief materials, sexual harassment and enjoy little scope of participation in any response or management activities. Likewise, they also suffer from inverse care law after disaster. Contrary to that, disaster also creates a condition to accrue diverse positive and constructive impacts including women׳s transformative role which often do not get reported. Disaster leads the planners to follow not merely the compensatory principle but also restoration and augmentation principles which give more benefits to the low income group of the coast. Nevertheless, in the coast the higher is the loss of property, the lower is the tendency among the dwellers to invest which has a long-lasting effect on capital formation and social development.

TL;DR: In this article, a tourism disaster vulnerability framework was developed to facilitate the systematic analysis of the underlying vulnerability drivers, and the results from 73 interviews highlight common, as well as idiosyncratic, factors that shape the islands' hazardscapes and vulnerabilities.
Abstract: Islands are known to be vulnerable to natural hazards, resulting in substantial risks for their tourism industries. To facilitate the systematic analysis of the underlying vulnerability drivers, a tourism disaster vulnerability framework was developed. The conceptual model then guided qualitative empirical research in three regions: the Caribbean, the South Pacific, and the Indian Ocean. The results from 73 interviews highlight common, as well as idiosyncratic, factors that shape the islands’ hazardscapes and vulnerabilities. Key vulnerabilities included social, economic, political, and environmental dimensions. Probably, the most critical vulnerability driver is the lack of private sector investment in disaster risk reduction. This is interrelated with deficient planning processes, on-going demand for coastal products, lack of political will, and poor environmental conditions. Notwithstanding many barriers, some businesses and organisations engage proactively in addressing disaster risk. The paper’s empirical evidence supports the validity of the framework, and suggestions for further research are made.

TL;DR: The authors investigated the impact that flooding from a major US hurricane had on household finance and found that higher flooding results in larger reductions in total debt and lower debt levels appear to be driven by homeowners using flood insurance to repay their mortgages rather than to rebuild.
Abstract: Little is known about how affected residents are able to cope with the financial shock of a natural disaster. We investigate the impact that flooding from a major US hurricane had on household finance. Spikes in credit card borrowing and overall delinquency rates for the most flooded residents are modest in size and short-lived. Greater flooding results in larger reductions in total debt. Lower debt levels appear to be driven by homeowners using flood insurance to repay their mortgages rather than to rebuild. Debt reductions are larger in census tracts where mortgages were likely to be originated by non-local lenders.

TL;DR: In this article, a simple two-period equilibrium model of the economy is used to demonstrate the potential effects of extreme event occurrences such as natural or humanitarian disasters on economic growth over the medium to long-term.
Abstract: We demonstrate, using a simple two-period equilibrium model of the economy, the potential effects of extreme event occurrences - such as natural or humanitarian disasters - on economic growth over the medium- to long-term. In particular, we focus on the effect of such shocks on investment. We examine two polar cases; an economy in which agents have unconstrained access to capital markets, versus a credit-constrained version, where the economy is assumed to operate in financial autarky. Considering these extreme cases allows us to highlight the interaction of disasters and economic underdevelopment, manifested through poorly developed financial markets. The theoretical analysis shows that the shock of a disaster occurrence could have lasting effects on economic growth only if agents face borrowing constraints. The predictions of our theoretical model are then tested using a panel of data on natural disaster events at the country-year level, covering the period 1979-2007. We find that for countries with low levels of financial sector development, natural disaster events exert a significant negative impact on economic growth. In particular, where access to credit is problematic, the negative effects of disasters on growth are persistent over the medium- term. These results are robust to various checks. Our findings suggest that natural disasters do represent significant threats to economic development in poor countries.

TL;DR: Two major evacuation strategies are reported, Demand Strategies (DS) and Speed Strategies (SS), which provide better evacuation results in smart cities settings, which are among the most crucial dimensions of smart and future cities design.
Abstract: Smart cities have recently become the mainstream approaches for urbanisation. Environmental, social and economic sustainability, digital inclusion and high quality of life are considered important elements in smart cities design. Emergency response system and resilience are among the most crucial dimensions of smart and future cities design due to the increase in various disruptions caused by frequent manmade and natural disasters such as September 2001 and Philippines Typhoon Haiyan 2013. Disasters cause great economic and human losses each year throughout the world. Transportations and Telecommunications play a crucial role in disaster response and management. Our research is focused on developing emergency response systems for disasters of various scales with a focus on transportation systems. We have proposed and evaluated a disaster management system that uses Intelligent Transportation Systems including Vehicular Ad hoc Networks (VANETs), mobile and Cloud Computing technologies. In this paper, we report our recent work on two major evacuation strategies, Demand Strategies (DS) and Speed Strategies (SS), which provide better evacuation results in smart cities settings.

TL;DR: The authors survey the relevant literature from recent disasters in mostly developed countries in order to explore the wider role of schools in disaster preparedness, response and recovery, concluding with a set of recommendations for integrating schools into disaster planning.
Abstract: In order to contextualise the articles in this special issue, this introductory article surveys the relevant literature from recent disasters in mostly developed countries in order to explore the wider role of schools in disaster preparedness, response and recovery. The first section argues that as schools are hubs of their communities, it is important to understand the literature on communities in disaster contexts. This is followed by recent examples of school experiences of disasters, particularly in Japan, New Zealand and Australia. The final section synthesises the literature on children and young people in disaster contexts. The article closes with a set of recommendations for integrating schools into disaster planning.

TL;DR: In this article, the authors examined how the Mary Queen of Vietnam (MQVN) garnered social capital within its surrounding community to pursue successful community development in the absence of and opposition to governmental support and political resistance.
Abstract: Because governmental structures put in place to mitigate disaster risks and aid communities in the disaster recovery process have, at times, proven to be inadequate, reliance on other types of organizations is necessary for some communities to survive. Although there are a number of different actors that played a role in the reestablishment of communities within New Orleans since Hurricane Katrina took place, the Mary Queen of Vietnam (MQVN) Catholic Church is a prime example of how a community-based organization stepped in to address the needs of its community. This article examines how MQVN garnered social capital within its surrounding community to pursue successful community development in the absence of and opposition to governmental support and political resistance. This article will first review the government failure and decrease in civic trust that fostered a robust third-sector response in disaster recovery and redevelopment. Then, using social capital theory, the article supports the notion that civic distrust and confidence is derived from government and institutional performance, rather than increasing individualism or declining social trust. Finally, implications for federal disaster policy and third-sector disaster interventions are proposed. In August of 2005, Hurricane Katina struck the Gulf Coast, flooding 80 percent of the City of New Orleans (Associated Press, 2005). Until Superstorm Sandy, this disaster was seen as the most destructive natural disaster to impact the United States in recorded history. The disaster illustrated the social vulnerability of urban populations living in hazard prone regions, serving as a vivid reminder to developed nations that regardless of a nation’s level of development, their communities are still vulnerable to severe natural phenomena. Moreover, the disaster illustrated that a community’s vulnerability to disasters was not only a product of the built environment’s varying resistance to disasters and a community’s physical proximity to hazards, but also a byproduct of social dynamics that contribute to the vulnerability of populations (Cutter et al., 2008; Miller & Rivera, 2008). The subsequent effects of these social dynamics, when placed under the pressure of a severe natural disaster, illustrates to both the directly affected communities and the rest of the nation, that organizational,

TL;DR: A crowdsourcing-based approach for obtaining useful volunteer information for the context of flood risk management and an experimental evaluation was performed in order to verify the effectiveness of this approach.
Abstract: The number and intensity of floods have increased worldwide due to climate change, causing more damage, deaths and economic impacts than any other natural disaster. Coping with this type of disaster requires up-to-date, complete and accurate information about the current state of environmental variables. To make a contribution in this context, this paper proposes a crowdsourcing-based approach for obtaining useful volunteer information for the context of flood risk management. Furthermore, an experimental evaluation was performed in order to verify the effectiveness of this approach.

TL;DR: In this paper, the authors proposed the use of social enterprise to buttress the supply chains for distribution of essential goods by coordinating with micro-retailers before and after floods.
Abstract: Floods are the most frequent category of disasters worldwide. Among all geographic regions, Asia has suffered the most. While there are several ongoing humanitarian efforts and initiatives, we believe there is a new opportunity to coordinate “last mile” humanitarian efforts in the event of a flood using micro-retailers. Because micro-retailers are the “last mile” nodes in traditional retail supply chains in many Asian countries, we propose the use of social enterprise to buttress these supply chains for distribution of essential goods by coordinating with micro-retailers before and after floods. We also present a stylized model to quantify the benefits of doing so.

TL;DR: If initial social capital is very low (thus allowing for post-disaster looting and violence), then the impact of the trust-increasing effect is smaller, and it is shown that the effect of the disaster was not transitory, but that it persisted and actually increased over time.
Abstract: Chile has a long-standing history of natural disasters and, in particular, earthquakes. The latest big earthquake hit Chile on 27 February 2010 with a magnitude of 8.8 on the Richter scale. As an event that had a profound impact on significant portions of the population, the earthquake could theoretically have served to build trust by promoting new trust networks through the enhancement of distant family ties and the interaction between affected neighbours. This study offers an empirical analysis of this theory in the Chilean case. It finds that if initial social capital is very low (thus allowing for post-disaster looting and violence), then the impact of the trust-increasing effect is smaller. It also shows that the effect of the disaster was not transitory, but that it persisted and actually increased over time.

TL;DR: An overview of a Balloon-powered Internet for everyone is described, where a set of high-altitude balloons ascends to the stratosphere and creates an aerial wireless network that could allow developing countries to avoid the using of expensive underground infrastructure.
Abstract: This paper describes an overview of a Balloon-powered Internet for everyone. Currently we are using the internet service through Internet Service Providers to connect globally. Loon purpose is to provide wireless network to remote areas through of a set of high altitude balloon equipped with advanced sophisticated wireless transceivers to connect people globally. This technology could allow developing countries to avoid the using of expensive underground infrastructure. What is Project Loon? In the evolution of the Internet nowadays, some population of the world enjoys the benefits of the Internet. According to Google™, two-thirds of people on the earth, reliable Internet connection is still out of reach. To solve this global problem, Google™ developed an innovative project called the “LOON”, to provide broadband for free in rural and remote areas, as well as to improve communication during and after natural disasters or a humanitarian crisis. During a crisis, connectivity is really significant because information in itself is really lifesaving. Here the key concept is a set of high-altitude balloons ascends to the stratosphere and creates an aerial wireless network (see Fig. 1). The technology designed in the project could allow countries to avoid using expensive underground infrastructure. [1][2]

TL;DR: In this paper, the authors explored the challenges involved in building a disaster resilient built environment and proposed a set of recommendations to address these prevailing concerns and to build a more resilient built environments within cities.
Abstract: With the increase in occurrences of high impact disasters, the concept of risk reduction and resilience is widely recognised. Recent disasters have highlighted the exposure of urban cities to natural disasters and emphasised the need of making cities resilient to disasters. Built environment plays an important role in every city and need to be functional and operational at a time of a disaster and is expected to provide protection to people and other facilities. However, recent disasters have highlighted the vulnerability of the built assets to natural disasters and therefore it is very much important to focus on creating a disaster resilient built environment within cities. However the process of making a disaster resilient built environment is a complex process where many challenges are involved. Accordingly the paper aims at exploring the challenges involved in building a disaster resilient built environment. Paper discusses the findings of some expert interviews and three case studies which have been conducted in Sri Lanka by selecting three cities which are potentially vulnerable to threats posed by natural hazards. The empirical evidence revealed, lack of regulatory frameworks; unplanned cities and urbanisation; old building stocks and at risk infrastructure; unauthorised structures; institutional arrangements; inadequate capacities of municipal councils; lack of funding; inadequacy of qualified human resources; and corruption and unlawful activities as major challenges for creating a disaster resilient built environment within Sri Lankan cities. The paper proposes a set of recommendations to address these prevailing concerns and to build a more resilient built environment within cities.

TL;DR: In this article, the authors identify the interaction between disaster risk and development as a key research gap; taking account of and balancing development opportunities with disaster risk will require a paradigm shift in the way we think about and do both development and disaster risk management.
Abstract: The risks from floods have been rising globally due to increasing population, urbanization and economic development in hazard prone areas. The number of flood disasters throughout the world nearly doubled in the decade from 2000-2009 compared to the previous decade. There have been more flood disasters in the last four years (2010-2013) than in the whole decade of the 1980's. Evidence indicates that climate change-induced sea level rise, storm surge and more intense flooding will reinforce this trend unless risk management measures are undertaken immediately to well manage future losses and make communities more resilient to flooding. It is widely recognized that there is a mutually reinforcing relationship between disaster risk and development: disasters impact development and development impacts disasters. Evidence shows that repeated disasters undermine long-term socio-economic objectives. This is particularly evident in low income countries where disasters can impede the development process. The extensive time required to recover from damage, loss of capacity with which to rebuild and systemic risk negatively affect livelihoods in these countries, in the extreme case trapping people in poverty. In developed countries, recent floods triggered massive economic losses and undermined long-term competitiveness. The impact of disasters is felt most acutely by households and communities. In both developing and developed countries alike, local level studies strongly indicate that the poor suffer disproportionately due to the lack of financial and social safety nets, and institutional representation. Development can affect disaster risk via three main channels: by (1) increasing the physical assets and people exposed to the risk, (2) increasing the capacity to reduce the risk, respond to the risk and recover from the risk and (3) increasing or decreasing the vulnerability based on specific development strategies chosen. We identify this interaction as a key research gap; taking account of and balancing development opportunities with disaster risk will require a paradigm shift in the way we think about and do both development and disaster risk management.

TL;DR: The problems of current information network systems are analyzed and the systems and functions required for future large-scale disasters are suggested to improve the disaster information network and system through network recovery activity.
Abstract: Recently serious natural disasters such as earthquakes, tsunamis, typhoons, and hurricanes have occurred at many places around the world. The East Japan Great Earthquake on March 11, 2011 had more than 19,000 victims and destroyed a huge number of houses, buildings, loads, and seaports over the wide area of Northern Japan. Information networks and systems and electric power lines were also severely damaged by the great tsunami. Functions such as the highly developed information society, and residents' safety and trust were completely lost. Thus, through the lessons from this great earthquake, a more robust and resilient information network has become one of the significant subjects. In this article, our information network recovery activity in the aftermath of the East Japan Great Earthquake is described. Then the problems of current information network systems are analyzed to improve our disaster information network and system through our network recovery activity. Finally we suggest the systems and functions required for future large-scale disasters.

Abstract: Drought is often a hidden risk with the potential to become a silent public health disaster. It is difficult to define precisely when it starts or when it is over, and although it is a climatological event, its impacts depend on other human activities, and are intensified by social vulnerability. In Brazil, half of all natural disaster events are drought related, and they cause half of the impacts in number of affected persons. One large affected area is the semiarid region of Brazil’s Northeast, which has historically been affected by drought. Many health and well-being indicators in this region are worse than the rest of the country, based on an analysis of 5565 municipalities using available census data for 1991, 2000 and 2010, which allowed separating the 1133 municipalities affected by drought in order to compare them with the rest of the country. Although great progress has been made in reducing social and economic vulnerability, climate change and the expected changes in the semiarid region in the next few decades call for a review of current programs, particularly in public health, and the planning of new interventions with local communities. This study reviews the literature, analyzes available data and identifies possible actions and actors. The aim is to ensure there will be sufficient and sustainable local adaptive capacity and resilience, for a population already living within the limits of environmental vulnerability.

Abstract: Because of extreme vulnerability to natural disasters, Nepal is considered a disaster hotspot in the world. For a small country with just a little less than 30-million population, the disaster statistics are always frightening. School students of Nepal are also in extreme risk of natural disasters, especially when they are in schools. In this context, a few education programmes for disaster risk reduction (DRR) have already been initiated and the results have also been already documented. However, an evaluation of the real scenario with the help of an independent research is still lacking. Therefore, this research aims to explore benefits of existing education programmes of DRR in Nepal. Altogether, 124 students from 17 districts were interviewed and various questions related to disaster information, disaster knowledge, disaster readiness, disaster awareness, disaster adaptation, and disaster risk perception were asked. Statistical analysis such as histogram analysis, distribution analysis, bivariate corr...
