Índice de risco de chefia aplicado ao mapeamento do risco de inundações urbanas em cidades turísticas de pequeno porte: O caso de Paraty/RJ

Abstract

Unplanned urban growth generally leads to the occupation—mainly by socioeconomically vulnerable populations—of areas with a higher probability of adverse events. Small tourist cities may experience significant problems in their activities when facing floods that affect the operation of attractions, businesses, and local services, resulting in substantial economic losses. Mapping flood risks with an emphasis on resilience proves to be fundamental for reducing the impact of such events and for enhancing the response capacity of the affected population. The construction of an index based on indicators that are representative of the physical reality but adaptable to each location is essential to support decision-making and the allocation of public resources aimed at strengthening urban resilience. The research proposed here seeks to develop an integrative index that encompasses the main risk-enhancing aspects in small tourist cities, while maintaining a flexible structure that can be adjusted and applied to cities with different characteristics. This proposed index builds on a previous initiative, namely the Flood Risk Index (Zonensein, 2007). The case study of this work focuses on the urban area of the tourist municipality of Paraty/RJ, which is stratified into risk zones, where the influence of the indicators on its construction can be observed.
