A pandemic devastates the lives of global citizens and causes significant economic, social, and political disruption. Evidence suggests that the likelihood of pandemics has increased over the past century because of increased global travel and integration, urbanization, and changes in land use with a profound affectation of society–nature metabolism. Further, evidence concerning the urban character of the pandemic has underlined the role of cities in disease transmission. An early assessment of the severity of infection and transmissibility can help quantify the pandemic potential and prioritize surveillance to control highly vulnerable urban areas in pandemics. In this paper, an Urban Vulnerability Assessment (UVA) methodology is proposed. UVA investigates various vulnerability factors related to pandemics to assess the vulnerability in urban areas. A vulnerability index is constructed by the aggregation of multiple vulnerability factors computed on each urban area (i.e., urban density, poverty index, informal labor, transmission routes). This methodology is useful in a-priori evaluation and development of policies and programs aimed at reducing disaster risk (DRR) at different scales (i.e., addressing urban vulnerability at national, regional, and provincial scales), under diverse scenarios of resources scarcity (i.e., short and long-term actions), and for different audiences (i.e., the general public, policy-makers, international organizations). The applicability of UVA is shown by the identification of high vulnerable areas based on publicly available data where surveillance should be prioritized in the COVID-19 pandemic in Bogotá, Colombia.

This paper presents the urban vulnerability assessment as a complementary resource in heritage preservation policies, through the analysis of the thirty-nine medium-sized cities that have been listed as Historical Ensemble in Andalusia (Spain). The research seeks to make a sequential approach that addresses, from the general –the conceptual framework on urban vulnerability and the characterization of the analysis sample– to the particular  –the analysis of the socio-economic, socio-demographic or residential vulnerability applied to the intermediate scale which has not been in-deep studied yet–. For this, it proposes to adopt the methodology implemented by the Spanish Ministry of Development in the Atlas of Urban Vulnerability, providing a territorial lecture of the results. The study concludes that medium-sized cities do not present a level of vulnerability lower to the largest ones but detecting specific urban weaknesses that should be addressed to improve the response of these cities to heritage preservation.

Many-objective optimization methods have proven successful in the integration of research attributes demanded for urban vulnerability assessment models. However, these techniques suffer from the curse of the dimensionality problem, producing an excessive burden in the decision-making process by compelling decision-makers to select alternatives among a large number of candidates. In other fields, this problem has been alleviated through cluster analysis, but there is still a lack in the application of such methods for urban vulnerability assessment purposes. This work addresses this gap by a novel combination of visual analytics and cluster analysis, enabling the decision-maker to select the set of indicators best representing urban vulnerability accordingly to three criteria: expert’s preferences, goodness of fit, and robustness. Based on an assessment framework previously developed, VisualUVAM affords an evaluation of urban vulnerability in Spain at regional, provincial, and municipal scales, whose results demonstrate the effect of the governmental structure of a territory over the vulnerability of the assessed entities.

Abstract The vulnerability of a city is an important index to evaluate the healthy development of a city, and also an important guide to the harmonious and sustainable development of resource-based cities. This paper constructs the vulnerability assessment system of resource-based cities from four dimensions of resources, ecology, society and economy, and puts forward the Entropy Weight-TOPSIS model to study the dynamic changes of urban vulnerability in the resource-based city—Karamay. The research results show that the urban vulnerability score of Karamay rose steadily from 2008 to 2017, but the overall vulnerability score was always between 0.1 and 0.2, indicating that the urban vulnerability of Karamay has not significantly improved and is still in the stage of extremely fragile economic and social comprehensive development. The ecological vulnerability, social vulnerability and economic vulnerability of Karamay show a good trend of improvement, and social development contributes the most to the comprehensive vulnerability of the city, while the score of resource vulnerability shows a significant decline. Resource development and utilization is still the key to determine the healthy and sustainable development of Karamay.
