“…Results demonstrate that it is a robust approach to construct a composite vulnerability index using the four categories of vulnerability factors. The application of the vulnerability index derived from various aspects of earthquake hazard and vulnerability is more accurate than using only physical and/or socio-economic characteristics of urban areas at local [55,133,134]. The outline of the hybrid ANP-ANN model developed in this contribution is flexible, as it is an integrated approach to earthquake vulnerability assessment.…”

“…The main advantage of the research was its simplicity in applying the applying the indices, which could be a solution for different stakeholders in vulnerability studies. Thus, vulnerability assessment fits into the general approach of informed decision making which links academic research, policy, and practice [133]. Since all indicators have neither equal importance value nor play an effective role in vulnerability, assessing vulnerability cannot be reviewed only by an individual inspection of each element.…”

A Hybrid Analytic Network Process and Artificial Neural Network (ANP-ANN) Model for Urban Earthquake Vulnerability Assessment

et al. 2018

Vulnerability assessment is one of the prerequisites for risk analysis in disaster management. Vulnerability to earthquakes, especially in urban areas, has increased over the years due to the presence of complex urban structures and rapid development. Urban vulnerability is a result of human behavior which describes the extent of susceptibility or resilience of social, economic, and physical assets to natural disasters. The main aim of this paper is to develop a new hybrid framework using Analytic Network Process (ANP) and Artificial Neural Network (ANN) models for constructing a composite social, economic, environmental, and physical vulnerability index. This index was then applied to Tabriz City, which is a seismic-prone province in the northwestern part of Iran with recurring devastating earthquakes and consequent heavy casualties and damages. A Geographical Information Systems (GIS) analysis was used to identify and evaluate quantitative vulnerability indicators for generating an earthquake vulnerability map. The classified and standardized indicators were subsequently weighed and ranked using an ANP model to construct the training database. Then, standardized maps coupled with the training site maps were presented as input to a Multilayer Perceptron (MLP) neural network for producing an Earthquake Vulnerability Map (EVM). Finally, an EVM was produced for Tabriz City and the level of vulnerability in various zones was obtained. South and southeast regions of Tabriz City indicate low to moderate vulnerability, while some zones of the northeastern tract are under critical vulnerability conditions. Furthermore, the impact of the vulnerability of Tabriz City on population during an earthquake was included in this analysis for risk estimation. A comparison of the result produced by EVM and the Population Vulnerability (PV) of Tabriz City corroborated the validity of the results obtained by ANP-ANN. The findings of this paper are useful for decision-makers and government authorities to obtain a better knowledge of a city's vulnerability dimensions, and to adopt preparedness strategies in the future for Tabriz City. The developed hybrid framework of ANP and ANN Models can easily be replicated and applied to other urban regions around the world for sustainability and environmental management.

“…In fact, when complex decision has to be done, taking into account also negative issues allows to detect potential criticalities and risks that could have direct effect on the project. Vulnerability could be described both as the exposure of elements to adverse impacts (Alexander 2012) and as the measure of the damage (Blaikie et al 1994) or as a combination of the exposure and the resistance (Villegas-González et al 2017;Alexander 2012). In this context the socio-economic, socio-cultural and the natural context are going to be evaluated both considering negative impacts on the territory and their measure.…”

The introduction of the concept of sustainable development in the field of cultural heritage preservation has stressed the importance of a holistic approach. Achieving a balance among cultural significance retention and economic development is a challenging goal, even more for fragile and vulnerable contexts with limited economic and social resources, low return expectations and a huge tangible and intangible cultural heritage. Given such a complexity decisions about where to place valorisation interventions with the purpose to activate synergies with existing projects and trigger economic and social development processes require to be based on robust evaluation methodologies. According to this instance, Spatial Multicriteria Analysis (SMCA) can support decision-makers along all the steps of the decision process, moving from the intelligence phase to the design and, finally, to the choice one. Within this approach, the study has been focused on the intelligence phase, in order to define a multidimensional analytical framework aimed at mapping widespread cultural heritage with a special attention to its territorial features. The proposed methodological evaluation framework points out the challenge of structuring a decision problem related to the inner areas regeneration by the reuse of cultural heritage placed along slow mobility routes. The results are value maps that provide recommendations for placing culture heritage preservation and reuse interventions, meant as territorial catalyst.

“…El segundo, un taller de redes sociales e identidad cuyo propósito fue evaluar desde la experiencia comunitaria, elementos que ayudaran a esbozar características de la identidad local y regional, así como a vislumbrar los sueños compartidos. Por último, el tercer taller sobre resiliencia tuvo como objetivo reconocer las cualidades y fortalezas que permiten a las personas enfrentar positivamente situaciones desfavorables (Villegas-González et al, 2017b). El objetivo de estos tres ejercicios fue explorar los sentidos del agua, las experiencias con construcciones palafíticas en las escuelas, pero además identificar variables que debían ser incluidas en los modelos.…”

Talleres de participación con las comunidades Fueron diseñados talleres de participación con las comunidades con el fin de conocer las experiencias que han vivido durante desastres naturales (Villegas-González et al, 2017c)y, a partir de la interacción con estas, se buscó formular indicadores sociales que dieran cuenta de la vulnerabilidad social frente al riesgo. El objetivo de estos tres ejercicios en San Marcos fue explorar los sentidos del agua, las experiencias con construcciones palafíticas en las escuelas, pero además identificar variables que debían ser incluidas en el modelo.…”

Los análisis de riesgo por inundación en Colombia, se han enfocado en la modelación física de la amenaza y en la valoración de la vulnerabilidad física y social. Pero no se han integrado estos dos análisis en la evaluación del riesgo. El trabajo presentado hace énfasis, en la inclusión de los elementos sociales y el conocimiento de las comunidades, como base para la generación de modelos de evaluación del riesgo. Específicamente, se propone un modelo para hacer modelos, en el marco de procesos de participación local. Para esto se utiliza la metodología GAIA. Los artefactos desarrollados son: MOJANA, MOJANACOOP y MOJANAREAL, los cuales reflejan en su diseño los principales componentes del metamodelo. Las variables y procesos a modelar se representan a través de las reglas, que permiten integrar el fenómeno de la inundación y las características del sistema social. Para el desarrollo de los modelos se utiliza el caso de estudio de la ecorregión de la Mojana y se pudo concluir que las variables más importantes para analizar la vulnerabilidad social son: la condición de habitabilidad, las actividades productivas, los procesos de cooperación y, el acceso a la salud y educación de las comunidades locales. Para el caso específico de la ecorregión de la Mojana, la vulnerabilidad social es media y esta se encuentra relacionada con las formas de adaptación a los procesos de inundación
