As indicated by the literature assessed within this chapter, keeping windows of opportunity open for CRD will necessitate urgent action, even under diverse assumptions regarding how future mitigation and adaptation interventions evolve. If nations are to collectively limit warming to well below 2ºC, for example, unprecedented emissions reductions will be necessary over the next decade . These reductions would necessitate rapid progression of system transitions . If, despite the Paris Agreement, future emissions trajectories take the world beyond 2ºC, a greater demand will be placed on adaptation as a means of enhancing the resilience of development. Given the long-lived nature of human systems, and the built environment in particular, significant adaptation investments would be needed over the near-term to meet this demand. Yet, it is important to note that, even in the absence of consideration for climate change, substantial development needs exist for communities around the world at present. Hence, a robust strategy for the pursuit of CRDPs is a near-term focus on portfolios of policies and practices that promote human and ecological well-being.
