Patterns and Limitations of Urban Human Mobility Resilience under the Influence of Multiple Types of Natural Disaster.

Abstract: Natural disasters pose serious threats to large urban areas, therefore understanding and predicting human movements is critical for evaluating a population’s vulnerability and resilience and developing plans for disaster evacuation, response and relief. However, only limited research has been conducted into the effect of natural disasters on human mobility. This study examines how natural disasters influence human mobility patterns in urban populations using individuals’ movement data collected from Twitter. We selected fifteen destructive cases across five types of natural disaster and analyzed the human movement data before, during, and after each event, comparing the perturbed and steady state movement data. The results suggest that the power-law can describe human mobility in most cases and that human mobility patterns observed in steady states are often correlated with those in perturbed states, highlighting their inherent resilience. However, the quantitative analysis shows that this resilience has its limits and can fail in more powerful natural disasters. The findings from this study will deepen our understanding of the interaction between urban dwellers and civil infrastructure, improve our ability to predict human movement patterns during natural disasters, and facilitate contingency planning by policymakers.

Managing disaster risk in emerging economies

Abstract: This book presents papers on several events organized by the World Bank's Disaster Management Fund (DMF). The DMF's objectives are to help the Bank provide a more strategic and rapid response to disaster emergencies and to integrate disaster prevention and mitigation measures in all Bank activities. Part I of this book on risk identification contains chapters on the economic impacts on natural disasters in developing countries, including flooding, with the example of Buenos Aires; and time scales of climate and disaster. Part II explores aspects of reducing disaster risk, such as the relationship of infrastructure, natural disasters, and poverty; flooding issues in the United States, incentives for risk management and mitigation concerning cultural heritage; issues related to single-family housing, women, and children; and climate change from a development perspective. Part III looks at strategies for developing countries to more effectively share and transfer disaster risk from the angles of risk and insurance by the poor in developing countries; financing disaster mitigation for the poor; moral dimensions of risk transfer and reduction strategies; incentives for mitigation investment and risk management to encourage public-private partnerships; and linking catastrophe insurance and mitigating disaster losses.

Katrinanomics: The politics and economics of disaster relief

Abstract: Hurricane Katrina revealed massive governmental failure at the local, state and federal levels. This commentary brings the modern theory of property rights and public choice reasoning to bear in explaining why officials failed to strengthen New Orleans's levee system despite forewarning of its weaknesses, failed to pre-deploy adequate emergency supplies as the storm approached landfall and failed to respond promptly afterwards. Its main lesson is that no one should have expected government to be any more effective when confronted with natural disaster than it is in more mundane circumstances.

Opinion: Urban resilience efforts must consider social and political forces.

Abstract: Environmental disasters, ranging from catastrophic floods to extreme temperatures, have caused more than 30,000 deaths per year and more than US$ 250–300 billion a year in economic losses, globally, between 1995 and 2015 (1). Improved infrastructure and planning for extreme events is essential in urban areas, where an increasingly greater fraction of the world’s inhabitants reside. In response, international governmental and private initiatives have placed the goal of resilience at the center stage of urban planning. [For example, The 100 Resilient Cities Initiative (www.100resilientcities.org/); the Global Covenant of Mayors (https://www.compactofmayors.org/globalcovenantofmayors/); and the recent UN Habitat III (https://habitat3.org/the-new-urban-agenda)]. In addition, scientific and policy communities alike now recognize the need for “safe-to-fail” infrastructural design, and the potential role of green and blue infrastructure in mediating hydrological and climatic risks in cities (2). Fig. 1. Improving urban resilience could help cities better cope with natural disasters, such as neighborhood flood events in Mexico City pictured here. Data source: Unidad Tormenta, Sistema de Aguas de la Ciudad de Mexico. Nevertheless, the social and political norms, values, rules, and relationships that undergird and structure the myriad decisions made by public and private actors—what we call “socio-political infrastructure”—are likely to be as influential in urban vulnerability dynamics as “hard” infrastructure and environmental management. Urban planning for enhanced resilience and sustainability is ultimately a complex social and political process. Socio-political infrastructure creates patterns of behavior and action that shape the built environment. Developing more sustainable pathways of urban development hinges on making this socio-political infrastructure transparent and legible in the tools and approaches available for risk management. We argue that sustainability science is in the position to create the tools, methods, and strategies to identify, represent, and communicate the significance of these social and political processes to decision makers at all levels. In doing so, we can help … [↵][1]1To whom correspondence should be addressed. Email: Hallie.Eakin{at}asu.edu. [1]: #xref-corresp-1-1

Estimating the Economic Impact of Natural and Social Disasters, with an Application to Hurricane Katrina

Abstract: This paper examines taxable sales in the Los Angeles and Miami metropolitan areas to find evidence of the short- and long-run effects of the Rodney King riots and Hurricane Andrew on their respective economies. The comparison of these two events shows that the King riots had a long-term negative effect on Los Angeles' economy while Hurricane Andrew had a short-term positive effect on the Miami economy. The paper also applies the contrasting experiences of Los Angeles and Miami to New Orleans following Hurricane Katrina. In some ways, Katrina is a hybrid of these two events since it combines elements of both a natural disaster and a social disaster. The paper examines how Katrina is similar to each of the previous incidents and how these similarities might affect the recovery of New Orleans following the storm.
