Urban blue-green infrastructure (BGI) is pivotal in enhancing food safety and disaster risk reduction. By integrating natural systems such as green roofs, urban gardens, and water management systems, cities can address multiple challenges simultaneously. BGI not only improves the resilience of urban areas to flooding and extreme weather events but also contributes to sustainable food production and food security. These systems help mitigate risks associated with urban heat islands, reduce runoff and pollution, and support biodiversity, which is essential for robust food systems. Effective BGI can transform urban environments by creating multifunctional spaces that serve ecological, social, and economic purposes. For instance, green roofs and walls reduce stormwater runoff, while urban gardens enhance local food production and reduce reliance on long-distance food transportation. Moreover, the incorporation of blue infrastructure, like rain gardens and permeable pavements, plays a critical role in managing stormwater and reducing flood risks.
