Disaster risk reduction: A decision-making support tool based on the morphological analysis

Abstract

Risk management due to natural hazards is a multidimensional and complex problem since it requires the knowledge and experience of several disciplines. The effectiveness of risk management can be analyzed, inviting to the action through weakness identification of the urban area. This article proposes a methodology based on the morphological analysis to support the decision-making on disaster risk management, taking as a starting point the results of a holistic evaluation of the seismic risk. The results of the holistic evaluation of risk are achieved aggravating the physical risk using the contextual conditions, such as the socioeconomic fragility and the lack of resilience. In consequence, the risk mitigation can be performed through the reduction of the potential damage and consequences involved; and the improvement of social conditions.The proposed methodology allows prioritizing the risk reduction strategies according to i) performance level of component indicators involved into the Disaster Risk Management index, 𝐷𝑅𝑀𝑖; ii) physical risk factors dependent from the potential damages, and iii) aggravating factors involved in the aggravating coefficient. Moreover, it involves 35 strategies to reduce the physical risk and the aggravating social conditions of the urban area.The proposed methodology has been applied to the city of Mérida (Venezuela), located within an area of high seismic activity. The performance level of the indicators involved in the 𝐷𝑅𝑀𝑖 was evaluated by a survey to local experts. As a result, eleven strategies have been identified to reduce the potential damage and to improve the social conditions of this city.

<p>Challenges for Nurses in Disaster Management: A Scoping Review</p>

“…Even though identifying disaster risks is very challenging and requires great effort from governments and related agencies, it is a fundamental and essential step in disaster management. 4 The second step is preparedness, which involves education and training, as well as conducting drills and developing plans and policies. [5][6][7][8][9] Involved parties include caregivers, community members, and healthcare providers, including nurses and organizations.…”

Afet Risk Yönetiminde Yapay Zekâ Kullanımının Rolü

“…Doğal bir afetin gerçekleşmesi durumunda, başarılı bir risk yönetim süreci ortaya koymak kavramsal, bilimsel ve teknik açıdan hem karar mekanizmalarını hem de afetten etkilenen tüm kesimleri zorlayıcı bir unsur haline gelmektedir. Bu sebeple, özellikle afet öncesi dönemde afet risklerine dair ortaya konulan tüm göstergeler kentin tüm paydaşlarının erişimine açık, şeffaf, kolayca anlaşılır ve güvenilir olmak durumundadır [53,54].…”
