Nature as infrastructure has the potential to be a transformative concept for development. It goes beyond nature-based solutions or mitigating the impact of human development on nature. Infrastructure is traditionally defined as the organizational structures and facilities that allow for the operation of society. It should now be clear that nature is an inseparable part of it. The degradation of nature and biodiversity over the past decades thus poses an existential risk as much as climate change. This must be reversed quickly, together with climate change.
