Envisioning the future—Creating sustainable, healthy and resilient BioCities

Numerous challenges – from population increase to climate change threaten the sustainable development of cities and call for a fundamental urban green-blue resource management. Urban forests are vital in this transition, as they provide various ecosystem services allow re-shape re-think cities. Based on Europe-wide community effort with diverse experts centered around greening, we propose five key research fields generate knowledge required unlock changes management: circular bioeconomy, resilience, governance, social human environment, biodiversity. To support design greener, cooler, more inclusive resilient cities, all these require inter- transdisciplinary collaboration, engaging stakeholders transforming engagement functioning. We summarise main inter-, trans- und multi-disciplinary paths each field cross-cutting areas that can help address many face (e.g., modelling assessment microclimate). For further is needed e.g., innovation, participation, more. Finally, how identified gaps be implemented international coordinated effort, interdisciplinary networks).
