Abstract The exponential growth of urban areas is putting a strain on urban land and water resources, besides has serious implications on the urban environment. Blue-Green infrastructure (BGI) is an emerging solution for sustainable urban planning and efficient management of urban spaces. This article highlights the benefits offered by BGI and the available BGI technologies based on available scientific works. The relationship between environmental well-being, human health, and BGI has been examined from several recent literature reviews. The performance of various available BGI techniques and the models available have also been rigorously reviewed by consulting publications, peer-reviewed journal papers, documents, and books published by various sources. A major gap in performance evaluation of different BGI technologies has been attempted to be bridged by discussing in detail the available modelling tools. This review article discusses different BGI programs, strategies, benefits, and the drivers associated with the successful implementation. It will enable urban planners to select the best available BGI technologies based on goal-oriented applications, especially for land and water management. It would also serve to establish and popularize BGI techniques and designs among researchers, planners, and policy makers for application in their respective countries.
