Challenges in Creating a Disaster Resilient Built Environment

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.

Towards a business continuity information network for rapid disaster recovery

Abstract: Crisis Management and Disaster Recovery have gained immense importance in the wake of recent man and nature inflicted calamities such as the terrorist attacks of September 11th 2001 and hurricanes/earthquakes i.e. Katrina (2005), Wilma (2005) and Indian Ocean Tsunami (2004). Most of the recent work has been conducted for crisis management under terrorist attacks and emergency management services under natural disasters with private business continuity and disaster recovery a secondary concern. In this paper, we propose a model for pre-disaster preparation and post-disaster business continuity/rapid recovery. The model is utilized to design and develop a web based prototype of our Business Continuity Information Network (BCIN) system facilitating collaboration among local, state, federal agencies and the business community for rapid disaster recovery. We present our model and prototype with Hurricane Wilma as the case study.

Natural disaster management mechanisms for probabilistic earthquake loss

Abstract: High rates of urbanization, environmental degradation, and industrial development have affected all nations worldwide, but in disaster-prone areas, the impact is even greater serving to increase the extent of damage from natural catastrophes. As a result of the global nature of environmental change, modern economies have had to adapt, and sustainability is an extremely important issue. Clearly, natural disasters will affect the competitiveness of an enterprise. This study focuses on natural disaster management in an area in which the direct risks are posed by the physical effects of natural disasters such as floods, droughts, tsunamis, and rising sea levels. On a local level, the potential impact of a disaster on a company and how much damage (loss) it causes to facilities and future business are of concern. Each company must make plans to mitigate predictable risk. Risk assessments must be completed in a timely manner. Disaster management is also very important to national policy. Natural disaster management mechanisms can include strategies for disaster prevention, early warning (prediction) systems, disaster mitigation, preparedness and response, and human resource development. Both governmental administration (public) and private organizations should participate in these programs. Participation of the local community is especially important for successful disaster mitigation, preparation for, and the implementations of such measures. Our focus in this study is a preliminary proposal for developing an efficient probabilistic approach to facilitate design optimization that involves probabilistic constraints.

Disaster risk, social vulnerability, and economic development

Abstract: This paper examines the extent to which economic development decreases a country's risk of experiencing climate-related disasters as well as the societal impacts of those events. The paper proceeds from the underlying assumption that disasters are not inherently natural, but arise from the intersection of naturally-occurring hazards within fragile environments. It uses data from the International Disaster Database (EM-DAT), representing country-year-level observations over the period 1980-2007. The study finds that low-income countries are significantly more at risk of climate-related disasters, even after controlling for exposure to climate hazards and other factors that may confound disaster reporting. Following the occurrence of a disaster, higher income generally diminishes a country's social vulnerability to such happenings, resulting in lower levels of mortality and morbidity. This implies that continued economic development may be a powerful tool for lessening social vulnerability to climate change.
