The previous two chapters outlined how green infrastructure has developed as a concept and as an approach to planning over the past 15 years. Each highlighted a number of the key geo-spatial differences inherent to green infrastructure, as well as illustrating where areas of consensus exist. The following chapter acts as a conduit between these discussions and the case study chapters to come by framing these conceptual debates into an evaluative framework to blend the breadth of green infrastructure policy and decision-making with assessments of how green and blue spaces are being delivered around the world.
