Negotiating the green obstacle course: Ranking priorities and problems for municipal green infrastructure implementation

Abstract

This paper sets out the results of a study exploring, and ranking in order of perceived significance, the priorities and obstacles faced by smaller cities when implementing green infrastructure (GI) projects. The study captured the views of 49 municipal officers and elected representatives in cities of less than 500,000 population across four countries in northwest Europe, using a closed card sorting methodology as part of a semi-structured interview format. The results show a clear hierarchy in priorities, with particular attention paid to anthropocentric benefits to residents, especially the importance of aesthetics and liveability as a key objective in GI delivery, and the desirability of securing visible benefit to residents within the electoral cycle; longer-term objectives linked to environmental and economic challenges, although acknowledged in corporate policies, attract a lower priority when it comes to delivery, and may encounter trade-offs against other desired benefits. The greatest obstacle to GI delivery is not funding, as found in other studies, although this remains significant; rather, it is difficulty of collaborations and fragmentation within the city organisation which participants attributed to a lack of leadership and prioritisation of green initiatives. Capacity is also a clear issue, and the results highlight a lack of resources (including funding) but also skills in assembling evidence in support of projects, and staff time to bid for and deliver new GI proposals. When comparing these findings to others from larger cities, particularly those with a population over 1 million, the results suggest differences in prioritisation, critical mass, resources and capabilities and capacities influencing GI implementation, these are important to consider as they may prevent transferability of GI best practices from larger cities, who tend to be more active and innovative, to smaller scale cities. Co-production of knowledge, could offer considerable potential to improve GI implementation, but the design of any such schemes should recognise the issue of capacity by providing resources to allow participation of practitioners in smaller municipalities. Finally, respondents highlighted increasing environmental awareness of local communities and whilst the effect of this is yet to be seen, this was considered as having considerable potential in improving GI implementation in smaller municipalities.
