Decision Aid Models for Disaster Management and Emergencies

Abstract: Disaster management is a process or strategy that is implemented when any type of catastrophic event takes place. The process may be initiated when anything threatens to disrupt normal operations or puts the lives of human beings at risk. Governments on all levels as well as many businesses create some sort of disaster plan that make it possible to overcome the catastrophe and return to normal function as quickly as possible. Response to natural disasters (e.g., floods, earthquakes) or technological disaster (e.g., nuclear, chemical) is an extreme complex process that involves severe time pressure, various uncertainties, high non-linearity and many stakeholders. Disaster management often requires several autonomous agencies to collaboratively mitigate, prepare, respond, and recover from heterogeneous and dynamic sets of hazards to society. Almost all disasters involve high degrees of novelty to deal with most unexpected various uncertainties and dynamic time pressures. Existing studies and approaches within disaster management have mainly been focused on some specific type of disasters with certain agency oriented. There is a lack of a general framework to deal with similarities and synergies among different disasters by taking their specific features into account. This book provides with various decisions analysis theories and support tools in complex systems in general and in disaster management in particular. The book is also generated during a long-term preparation of a European project proposal among most leading experts in the areas related to the book title. Chapters are evaluated based on quality and originality in theory and methodology, application oriented, relevance to the title of the book.

Analysis of key factors for waste management in humanitarian response: An interpretive structural modelling approach

Abstract: Recent few years have witnessed a substantial growth in the frequency and magnitude of disasters. Natural disasters such as hurricanes and earthquakes hit a community without any prior signals or warning, resulting in high levels of devastation. This further leads to generation of waste and debris that pose threats to health and safety of associated population as well as hinder the recovery process. Hence, there is a necessity of an effective and efficient management of disaster waste. The present research analyses the factors that affect the successful implementation of disaster waste management. Initially the study aims to identify certain key factors from the literature as well as through consultation from domain experts. Next, the contextual relationship between the factors is studied by using Interpretive Structural Modelling approach. The analysis helps in determining factors that play influential role in disaster waste management. It is revealed that geography & terrain and type of disaster have a direct impact on speed of debris management. Although these factors cannot be controlled, but they must be kept in mind while devising waste management plans in vulnerable areas. The analysis further reveals that donors, disaster affected population and local & regional administration can contribute significantly in successful implementation of a disaster waste management plan. The study highlights how these factors influence other elements in waste management process during humanitarian response. Understanding the significance of these factors and giving them priority while planning and implementing disaster waste management can lead to an efficient relief delivery.

Understanding resilient urban futures: A systemic modelling approach

Abstract: The resilience of cities in response to natural disasters and long-term climate change has emerged as a focus of academic and policy attention. In particular, how to understand the interconnectedness of urban and natural systems is a key issue. This paper introduces an urban model that can be used to evaluate city resilience outcomes under different policy scenarios. The model is the Wellington Integrated Land Use-Transport-Environment Model (WILUTE). It considers the city (i.e., Wellington) as a complex system characterized by interactions between a variety of internal urban processes (social, economic and physical) and the natural environment. It is focused on exploring the dynamic relations between human activities (the geographic distribution of housing and employment, infrastructure layout, traffic flows and energy consumption), environmental effects (carbon emissions, influences on local natural and ecological systems) and potential natural disasters (e.g., inundation due to sea level rise and storm events) faced under different policy scenarios. The model gives insights that are potentially useful for policy to enhance the city’s resilience, by modelling outcomes, such as the potential for reduction in transportation energy use, and changes in the vulnerability of the city’s housing stock and transport system to sea level rise.

Global Change, Natural Disasters and Loss-sharing: Issues of Efficiency and Equity

Abstract: Global change in the form of climate warming, demographic developments, land use and capital movements to vulnerable regions will likely contribute to the already increasing human and economic losses from natural disasters. As countries in both the developing and developed world contemplate increasing losses from natural disasters, and as the victims relate these losses to human culpability, questions of burden-sharing for preventing and absorbing human and financial losses are becoming increasingly topical. This paper provides an overview of two forms of state and market burden-sharing at the local and global levels: collective loss-sharing after a major disaster by the state or the international community and the pre-disaster transfer of risk through insurance and other hedging instruments. With the recent attention given to the role of the private sector for apportioning and preventing disaster losses, we examine the efficiency and equity arguments for both collective loss-sharing and private risk transfer. We give special attention to the potential for governments of poor countries to transfer their natural disaster risks to the insurance and reinsurance markets, and to the international capital markets with newly developing hedging instruments, such as catastrophe bonds. We suggest that, under certain conditions, subsidized risk transfer can be an efficient and equitable way for industrialized countries to assume partial responsibility for the increasing disaster losses in poor countries, in addition to their role in aiding the economies of these countries.
