Mosaico verde-azul: masterplan de soluções baseadas na natureza para resiliência urbana no Bairro do Tirol, Natal/RN

Abstract

Contemporary cities have emerged from landscapes once dominated by greenery. The retreat of nature in the face of expanding urban gray, a result of centuries of human intervention, has created a scenario of urban vulnerability and signals the urgent need for adaptive measures. This study examines Nature-based Solutions (NbS) as strategies to mitigate the impacts of climate change, focusing on the core issue: the insufficiency of traditional drainage infrastructure to address hydrological events affecting the urban fabric of the study area—Tirol, Natal/RN—alongside the reduction of green spaces, which also exacerbates thermal discomfort. The research presents the development of a masterplan and prototypes for green areas utilizing NbS, grounded in bibliographic, documentary, and scientific research, spatial and typological analysis of green spaces, and graphic material production. Conceptual references on NbS, georeferenced data, local urban regulations, photographic surveys, mapping of flood points, and identification of potential sites for prototype implementation were analyzed, following functional, urban, and environmental criteria aligned with the study’s objectives. The study therefore seeks to initiate a more effective dynamic among gray, green, and blue infrastructures, paving the way for a balanced approach to urban heat regulation and stormwater management, and clearly demonstrating that resilient cities require the integration of these interconnected systems.
