There is a recognised need for a fundamental change in how the UK manages urban water and flood risk in response to increasingly frequent rainfall events coupled with planned urban expansion. Approaches centred on 'living with and making space for water' are increasingly adopted internationally. Nonetheless, widespread implementation of Blue-Green infrastructure (BGI) is currently hampered by barriers that impede uptake and innovation. We investigate the barriers to implementation of BGI in Newcastle, UK, through a series of semi-structured interviews with professional stakeholders. We identify and categorise 17 types of barrier and identify targeted strategies to overcome the dominant barriers. We recommend promotion of BGI's capacity to meet the objectives of multiple organisations and Local Authority departments, in addition to managing urban water. We conclude that strong business cases, supported by monetised evidence of benefits, and collaborative, inter-agency working could advance implementation of BGI within the current flood risk management legislation.

Modern urban flood and water management emphasises holistic strategies that reduce flood risk while providing co- benefits to urban economies, societies and environments. The 'Blue‐Green City' concept provides a viable framework for putting this into practice. Ningbo, is a coastal city with high flood risk, whose history as a Chinese 'water town' demonstrates that approaches to water management implicit to the 'Blue‐Green' concept were practiced in ancient times, and lessons can be learned from these applications. Furthermore, recent launch of the 'Sponge City' campaign by China's National Government demonstrates the political will to implement sustainable flood and water management in ways consistent with the 'Blue‐Green' ideals. Selection of Ningbo for a pilot project presents the opportunity to integrate new 'Sponge city' approaches with ancient 'Blue‐Green' principles, within the contexts of both new urban development and retrofit. Reinventing traditional approaches to urban water management and governance offers the possibility of maintaining flood risk at acceptable levels without constraining urban growth in China and other countries experiencing rapid urban development.
