Challenges of mainstreaming green infrastructure in built environment professions

© 2019, © 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Green infrastructure (GI) has been identified as a promising approach to help cities adapt to climate change through the provision of multiple ecosystem services. However, GI contributions to urban resilience will not be realized until it is more fully mainstreamed in the built environment and design professions. Here, we interrogate five key challenges for the effective implementation of GI: (1) design standards; (2) regulatory pathways; (3) socio-economic considerations; (4) financeability; and (5) innovation. Methods include a literature review, case studies, and interviews with resilience managers. We propose a people-centred and context-dependent approach to advance effective implementation of GI in urban planning. We highlight two underlying currents that run across all of the challenges–(1) the role of political will as a pre-condition for tackling all challenges holistically; and (2) the role of stakeholder engagement in achieving public support, harnessing funding, and maintaining and monitoring GI in the long term. Highlights: • The effective implementation of GI is context-specific and should adhere to the basic principles of appropriate technology. • Continuous community engagement is needed to ensure the inclusivity and multi-functionality of GI. • Challenges to successful GI are intersectional and therefore cannot be addressed singly in isolation

Systems-of-systems analysis of national infrastructure

National infrastructure is as much a priority in countries with a large stock of ageing infrastructural assets as it is for rapidly industrialising economies. Increasing attention is being paid to the risk and opportunities that the growing interdependence between infrastructural systems brings. However, there is no current methodology to enable long-term planning and future performance assessment of interdependent infrastructural systems. This paper makes the case for a long-term, cross-sectoral approach to analysing and planning the performance of national infrastructure systems. Such an approach is required to develop credible long-term visions for infrastructure provision and to analyse system performance across a range of possible futures. A preliminary version of a system-of-systems analysis for the UK is presented as an example. The implementation of a comprehensive, model-based approach is currently well under way
