This domain will initiate and sustain dialogue among the various stakeholders (private and public sector, architects, practitioners, policy maker), on nature-based solutions in the context of sustainable urbanization in cities and human well-being. The dialogue will address the available opportunities for existing and new NBS associated with materials, buildings and infrastructure in cities. The incorporation of NBS in building and at district level will also be explored. The generation of co-benefits through greening cities in relation with climate change adaptation and mitigation will be examined as well as the role of cultural heritage in renaturing cities and how to incorporate existing knowledge from historic buildings and districts in restoration with nature. The role and effectiveness of NBS in advancing sustainable and resilient infrastructure development and upgrade will be explored together with replication strategies for renovating cities with nature. Methods for robust monitoring of the performance and assessment of the impact of deployed NBS will be examined.
