    Climate Related Business Continuity Model for Critical Infrastructures

    Get PDF
    Climate change is more and more nowadays acknowledged to be associated with the natural hazards for which the society, and its Critical Infrastructures, need to anticipate and plan. The impact the climate-related hazards have to the functionality of different Critical Infrastructures (CI) is being discussed, focusing on the minimization of the disruption time of their critical services. This is achieved by means of a Business Continuity plan that is based on Business Impact Analysis and Risk Assessment of projected weather-related hazards. Business continuity planning is essential part of the resilience framework of the CIs, which EU-CIRCLE project proposes with regards to climate change. Guidelines are presented in order to provide a planned and controlled method for anticipating and responding to events that are likely to interrupt key business activities (Business Continuity Model) and suggestions upon adaptation of CIs to climate change are also given. For this purpose, information was collected from CI operators with regards to existing BC plans and adaptation measurements, by means of questionnaires, which is also presented herein.</p

    A Resilience Framework for Critical Infrastructure

    Infrastructures facilitate economic growth, protect human health and the environment and promote welfare and prosperity. Modern societies, therefore, rely heavily on continuous and reliable services provided critical infrastructure. Destruction to the infrastructure can lead to severe economic and social impacts and can also lead to loss of lives. To further complicate matters, modern infrastructures operate as a ‘system of systems’ with many interactions and interdependencies among these systems. Thus damage in one infrastructure system can cascade and result in failures and cascading effects onto all related and dependent infrastructures. To minimise such damages and impacts, it is vital to improve the resilience of critical infrastructure. This paper intends to present a resilience framework for critical infrastructure. Firstly a resilience definition has been established by reviewing the existing definitions. Then existing resilience frameworks were analysed to identity the suitable components for the proposed framework for critical infrastructure. Finally a layered approach framework has been developed to improve the resilience of critical infrastructure. The framework was developed based on comprehensive literature review. It was further validated with stakeholder feedback sessions. The framework consists of 4 layers that are independent and interdependent. Climatic hazards including current and future climate change, infrastructure, their networks and interdependencies, risks and impacts and capacities are the main layers. Each layer will have its unique features and its relationships with other layers. Climatic hazards will contribute to increased risks and impacts. Critical infrastructure is more vulnerable when exposed to climate hazard and uncertainty of climate change and will lead to risks and impacts. The capacities will help to determine the resilience level and will help to reduce the risks and impact. The framework serves as a diagnostic model to determine the existing resilience level of critical infrastructure and to improve the resilience by making necessary changes to the layers

    Vulnerability of the Emirati Energy Sector for Disaster: A Critical Review

    Get PDF
    Infrastructure in all its forms is a valuable asset and vulnerable to any natural or manmade hazard. The protection of infrastructure is thus one of the most important and difficult tasks for any government. The energy sector dominates in the UAE and consists of various assets - electricity, oil and natural gas that are geographically dispersed and connected by systems and networks. The protection of these systems and assets and within the energy sector especially, the safeguarding of oil and gas infrastructure from any and all internal and external threats should become top priority in the UAE. Threats to geopolitical and economic stability that need to be considered and prepared for include tectonic activity, climate change, nuclear energy, terrorism and war. This paper explores the disaster vulnerability of the Emirati energy sector with specific focus on Abu Dhabi and Dubai cities. It is based on secondary data, taken from various academic and professional sources, and primary data from a questionnaire survey administered on site at two electricity-generating plants in Abu Dhabi and Dubai. Forty questionnaires were distributed and 35 were returned back- 20 Abu Dhabi and 15 Dubai. Oil and gas sectors were identified as the most vulnerable energy sources in both Abu-Dhabi and Dubai. Risk from terrorism was thought to be the greatest hazard with every single respondent choosing it. This was despite the fact that respondents believe it to be one of the threats that the energy sector is prepared for

    Vulnerability reduction of infrastructure reconstruction projects

    Various infrastructure segments of numerous countries have been repeatedly subjected to natural and man-made disasters. The potential reason of damaging infrastructure facilities and their services is resultant disaster risks due to natural or man-made hazards connect with vulnerable infrastructure facilities and vulnerable communities. The simplest way to prevent or mitigate disaster losses is addressing vulnerabilities. The main study based on which this paper was compiled aimed at exploring and investigating the vulnerabilities of infrastructures and communities benefited from infrastructures and possible solutions to overcome them. This paper presents the literature review conducted on vulnerabilities of infrastructures and empirical evidence collated on best possible DRR strategies to overcome such vulnerabilities of infrastructures. The main study was conducted using case study strategy and the expert interviews. This paper is entirely based on the data collated from the expert interviews conducted in Sri Lanka and United Kingdom. The expert interviews discovered various DRR strategies to overcome the vulnerabilities of the infrastructure project

    Multi Hazard Scenarios in the Mendoza/San Juan Provinces, Cuyo Region Argentina

    This paper exposes major natural hazards inventory encountered in the two San Juan and Mendoza provinces, such as climatic, seismic, gravitational, and social/anthropic ones. The contrast between the high altitude of the region and low one is addressed in order to manage the inhomogeneity of prevention plans. The international road to Chile is greatly affected by gravitational hazards that proceed in out of run period and commercial traffic interruption, and large economic waste more than people vulnerability, as the urban areas are more affected by seismicity scenarios. But as gravitational hazard is affected by the seismicity it is proposed to analyze some co-hazard effect in a multi-scenarios approach from geology geography and mechanical modelling of events to explore the co-effects on the scenarios. Moreover, some similarities with the Rhone-Alpes region of France are evocated and may be of interest.Fil: Daudon, Dominique. University Grenoble Alpes; FranciaFil: Moreiras, Stella Maris.

    The role of urban built heritage in qualify and quantify resilience. Specific issues in Mediterranean city

    Get PDF
    The Mediterranean city represents a significant example of urban organism, based on masonry construction and characterized by typological processes of growth. The material consistency and the temporal continuity of built heritage in Mediterranean city make relevant its interpretation and analysis according to the resilient approach. The declination of this approach in many disciplines generated a substantial diversity among the definitions of resilience (Francis and Bekera, 2014). Consequently, frameworks, adopted for a quantitative or qualitative assessment, underline the lack of standardization and rigor in defining resilience measurements. A review of resilience literature and actual applications in urban context permit to understand that there are different operators working on the field: on the one hand there are international organizations, on the other hand there are academics. The review of both the two ambits of investigation intends to clarify specific properties and convergence points in order to trace an evolution of conceptual framework and to identify general features of urban resilience. This process is fundamental in focusing the main aims of the research program: the definition of the role of urban built heritage, given by the close correlation between masonry constructive technique, typologies and morphologies, its material value in urban system, and its relevance in Mediterranean city in constitution of urban resilience (UNISDR, 2012a). Despite an increasing number of academic studies concerning the role of built environment in defining and improving cities resilience, their major attention is still focused on street patterns and lifelines infrastructures. The paper concludes how the role of built heritage remains insufficiently explored and a correct definition of urban structure is still missing inside the domain of infrastructural resilience

    The recent 2010/2011 floods in the central and southern Queensland (Australia) prompted this research to investigate the application of geographical information system (GIS) and remote sensing in modelling the current flood risk, adaptation/coping capacity, and adaptation strategies. Identified Brisbane City as the study area, the study aimed to develop a new approach of formulating adaptation/coping strategies that will aid in addressing flood risk management issues of an urban area with intensive residential and commercial uses. Fuzzy logic was the spatial analytical tool used in the integration of flood risk components (hazard, vulnerability, and exposure) and in the generation of flood risk and adaptation capacity indices. The research shows that 875 ha, 566 ha, and 828 ha were described as areas with relatively low, relatively moderate, and relatively high risk to flooding, respectively. Identified adaptation strategies for areas classified as having relatively low (RL), relatively moderate (RM), relatively high (RH), and likely very high (LVH) adaptation/coping capacity were mitigation to recovery phases, mitigation to response phases, mitigation to preparedness phases, and mitigation phase, respectively. Integrating the results from the flood risk assessment, quantitative description of adaptation capacity, and identification of adaptation strategies, a new analytical technique identified as flood risk-adaptation capacity index-adaptation strategies (FRACIAS) linkage model was developed for this study
