How do we engage diverse voices and perspectives in sustainable urban development? Howcan biodiversity be integrated into the development of dense and green neighborhoods? Which types of data are needed, and how can data be used to balance neighborhood social and ecological identity in the face of rapid development? And how do we realize equitable access to housing and outdoor recreational spaces in the face of rising development costs? These questions and more were discussed at the launch of the Urban Solutions to Green Transitions Living Lab in Nordhavn. The results of the launch are described below including identified knowledge gaps and calls for a new research agenda focused on engagement forms and data to support just and inclusive approaches to sustainable urban development.
