In the past, damage from natural disasters was limited to the country directly affected, but as the world becomes one economic community, instances of damage spreading to other countries are increasing. Nonetheless, there has been insufficient research on the ripple effect of foreign disaster. This study thus analyzed the ripple effect on the domestic economy from foreign disaster, using a disaster scenario based on cases of China. The ripple effect was quantitatively calculated using an industry input coefficient. The results show that the direct damage was 0.08% of Gross Domestic Product (GDP), and the total amount of damage (including indirect damage) was 0.39% of GDP, thus demonstrating that foreign disaster could cause great damage to the domestic economy.

Frequent cases of water scarcity in Brazil reveal a water governance and administration crisis. During the water crisis (2013-2016), the São Paulo Metropolitan Region experienced a disaster scenario. This article analyses how it was constituted as a socially constructed disaster episode. A case study was carried out in the Novo Recreio neighbourhood (Guarulhos, SP) through ethnographic observations, interviews, and newspaper articles. The results were analysed based on the Pressure and Release Model (PAR). It was concluded that the water crisis period in SPMR has disproportionately affected the Guarulhos population, especially in Novo Recreio. Furthermore, the study demonstrated that public policies and the neighbourhood's territorial formation are related to its population's current frail living conditions and increased socio-environmental vulnerability in the face of continuous water scarcity, thus corroborating the social construction of the risk of water scarcity.

Abstract Disasters not only cause high mortality and suffering, but thwart developmental activities and damage local economies in process of formation. A part of the NW Himalayas, the Kashmir Valley is very distinct with respect to its location, topography, climate, socioeconomic structure, and strategic geopolitical nature owing to which it has witnessed a multitude of disasters ranging from local incidents of rockfalls to catastrophic earthquakes, and has often paid heavily in terms of loss of life and property. However, the information on most of the events is either partially reported or exaggerated or sometimes not recorded at all and largely scattered. Availability of organized and reliable record of past hazards and disasters is essential for tackling the risks and mitigating the future disasters. In this context, the present study attempts to address the lack of data availability by focusing on developing a dependable hazard and disaster catalogue of the Kashmir Valley by investigating into the existing literature and the available secondary data sources. A record of natural hazards and disasters most prevalent in the valley viz., earthquakes, floods, landslides and snow avalanches, has been compiled for the time period 1900 to 2020 by making use of various secondary sources, comprising of 1854 events with a range of triggers and impacts reported in the valley, which provide an insight into the spatial and temporal (frequency and distribution) trends of different hazard types for the selected time-period. Developing a catalogue of events reported in the Kashmir Valley can help in building a hazard and disaster scenario which serves as a reliable information source and is of great value from the perspective of regional design, planning and policy responses to promote disaster risk reduction.

Abstract Background Natural disasters and infectious diseases result in widespread disruption to human health and livelihood. At the scale of a global pandemic, the co-occurrence of natural disasters is inevitable. However, the impact of natural disasters on the spread of COVID-19 has not been extensively evaluated through epidemiological modelling. Methods We create an agent-based epidemiology model based on COVID-19 clinical, epidemiological, and geographic data. We first model 35 scenarios with varying natural disaster timing and duration for a COVID-19 outbreak in a theoretical region. We then evaluate the potential effect of an eruption of Vesuvius volcano on the spread of COVID-19 in Campania, Italy. Results In a majority of cases, the occurrence of a natural disaster increases the number of disease related fatalities. For a natural disaster fifty days after infection onset, the median increase in fatalities is 2, 59, and 180% for a 2, 14, and 31-day long natural disaster respectively, when compared to the no natural disaster scenario. For the Campania case, the median increase in fatalities is 1.1 and 2.4 additional fatalities per 100,000 for eruptions on day 1 and 100 respectively, and 60.0 additional fatalities per 100,000 for an eruption close to the peak in infections (day 50). Conclusion Our results show that the occurrence of a natural disaster in most cases leads to an increase in infection related fatalities, with wide variance in possible outcomes depending on the timing of the natural disaster relative to the peak in infections and the duration of the natural disaster.

Abstract This project develops a tailored and adaptive virtual reality platform to innovatively promote older adults’ disaster preparation in a socially engaging environment. The platform serves the following purposes: 1) assist older adults to develop tailored household emergency preparedness plans, 2) simulate extreme weather conditions and warnings for older adults to practice disaster response and develop relevant knowledge and skills as well as test and revise their emergency preparedness plans, 3) use the process as a social engagement tool to reduce social isolation and promote a sense of community. The virtual environments are designed in Unity to simulate extreme weather conditions/natural disasters and older adults are guided to use the HTC VR headset and experience the selected disaster scenario. The pilot VR platform will be tested among community-dwelling older adults in the Dallas-Fort Worth Metropolitan Area.

<p>Every year disasters affect hundreds of millions of people, causing damage that can take months or years to recover from. The reality of carrying out the processes of reconstruction and recreating functionality is a complex and difficult task; too often it is measured in a time period of several years. The issue to be addressed through this research is the response of the built (or rebuilt) environment to the requirements of people who have been displaced following a major disaster. This thesis develops a building typology and process that can adapt to the changing requirements of the stages of the redevelopment process in a post‐disaster scenario. The research focuses on natural disasters, more vulnerable populations and regions and specifically on housing reconstruction. It explores the idea of a solution that can be applied widely, to many different climates and contexts; the research question then amounts to ‘can a solution be created that can ‘evolve’ to meet the needs at each stage of a post disaster reconstruction scenario?’ The thesis explores existing post‐disaster response and reconstruction models and discusses the focuses and priorities of each. The requirements of displaced people are studied, in terms of response by the built environment, and the benefits of staged development versus end product discussed. The roles that major groups, such as local authorities and NGOs, play in orchestrating the reconstruction process are discussed as well as the important, and sometimes overlooked, role that those affected by the disaster may have. The discussion and research then informs the design proposal. Four sites are selected and used as parameters for developing the built response to the first stage of reconstruction. The selected sites are then used to show how a generic shelter may first be adapted to be suitable for a specific climate and context and then how they may be added to and grown to become permanent and suitable housing for the displaced people. The staged redevelopment process from a partially generic emergency deployment presented in this thesis can provide a solution, or framework for a solution, to many of the problems raised by the research and here, but it cannot be a solution by itself; architecture or design in post‐disaster scenarios must be supported and driven heavily by planning and management from local, national and international sources to be successful and fully realised.</p>

Purpose: Natural disasters disrupt not only the lives of individuals but also the functioning of society. Given the unpredictability of disasters and the uncertainty associated with them, preparation is the best way to mitigate and reduce the effects of the disaster. Design/methodology/approach: The study presents a mathematical model in the form of a multi-objective linear programming problem for the relief distribution from the airports which minimizes the total operational cost as well as travel time. Further, the solution approach and analytical results have also been discussed. Findings: The main aims at the preparedness stage are to identify and build infrastructures that might function as useful operation centres during a disaster. The study also provides decisions that include the type and number of vehicles for each affected location. Research limitations/implications: Airports can function as centres for relief collection and distribution. However, relief operations carried out through airports are often subject to problems such as stockpiling. Further, various modes are available for the transport of relief supplies- air, water, and land transport modes primarily. While aircraft and helicopters are faster, their costs of operation are too high. Instead, trucks are economical but very slow as compared to aircraft. Practical implications: The choice of model depends on many factors including the availability of vehicles, availability of routes, and criticality of situations. The choices made in turn affect the costs and the time of operations. Originality/value: The model converts a disaster scenario into a demand-supply problem with the aim being to decide allocations at specified intervals of time.
