The Potential of Blue–Green Infrastructures (BGIs) to Boost Urban Resilience: Examples from Spain

Urban areas globally are increasingly challenged by climate change, rapid urbanization, and environmental degradation, necessitating innovative solutions for sustainable development. Blue–Green Infrastructures (BGIs) have emerged as a promising approach, integrating water management systems with natural vegetative elements to create resilient urban landscapes. By fostering synergy between urban ecosystems and built environments, BGIs offer multifunctional benefits including flood mitigation, heat reduction, and biodiversity enhancement. This article examines the role of BGIs in boosting urban resilience, highlighting several exemplary projects in Spain in a qualitative and quantitative way that demonstrate its potential to transform urban areas into sustainable and adaptive spaces.
