Analysis of the Variation of Rio de Janeiro City Resilience in Different Scenarios

Disasters has been happening more frequently around the world. In Brazil, from 2010 to 2021 alone, almost two thousand fatalities and economic losses in the tens of billions of dollars were recorded due to these events. Therefore, in order to reduce and recover from losses, resilience is necessary. Resilient cities have the ability to better face the events they are exposed to, reducing losses over time. Measuring resilience can offer a possibility of greater knowledge of the territory, for planning and management purposes, but it is not a simple task. One possibility for measuring resilience refers to the use of tools derived from the concept of DROP (Disaster Resilience of Place) for the formulation of the BRIC index (Baseline Resilience Indicators for Communities), created by Cutter, Burton, and Emrich (2010). This method was adapted and applied to the city of Rio de Janeiro. This exploratory article aims to evaluate the relevance of the range of indicators proposed in the formation of the considered index by comparing its result for different application scenarios, gradually reducing the number of indicators used to arrive at the optimal number of indicators, simplifying the index without losing representativeness. Therefore, it is intended to evaluate the interference of the number of indicators on the final resilience obtained. The analyses show a small variation in the final indices, demonstrating the possibility of reducing the choice of indicators for measuring local resilience without direct harm to the final result. This index can be used for guidance in the application of disaster risk reduction policies, contributing to the analysis of strengths and weaknesses in the construction of more resilient cities.
