Una revisión de la infraestructura verdi-azul para la mitigación de inundaciones urbanas en regiones estuarinas

Abstract

CONDITION FOR PUBLICATION OF PROJECT. Floods are among the most common and severe environmental challenges globally, with critical impacts on urban areas. In this context, Blue-Green Infrastructures (BGIs) are recognised as sustainable strategies for flood mitigation. In urban coastal environments, such as estuaries, there is a growing need to understand advances in research on flood management using BGIs to improve the effectiveness of risk reduction strategies. This work aims to analyse the scientific literature using bibliometric and systematic review techniques for field development mapping and identification of BGIs frequently used in estuarine cities. The approach considered i) analysis record obtention, ii) bibliometric study, and iii) document review. The bibliometric analysis covered 505 records from the Scopus and Web of Science databases. Results revealed notable production between 2019 and 2024, with 81.39% of publications, evidencing exponential growth at an annual rate of 21.15%. China leads the research, accounting for 41% of production, followed by the United States (13%) and India (10%). Keyword analysis identified five research clusters related to flood modelling, climate change adaptation, flood management solutions, techno-economic assessment, and integrated planning. Recent research trends have focused on urban flood resilience and modelling optimization. A review of 31 case studies indicated that the most commonly used BGIs in estuarine areas include green roofs, permeable pavements, rainwater harvesting, and bioretention cells. This study provides an update on the development and application of BGIs in urban and estuarine contexts, offering essential information for designing effective flood mitigation strategies in cities with these environments.
