Sharing a vision for high quality green infrastructure..

Organised by our own Hannah Hickman and Sarah O’Driscoll (Bristol City Council), the inaugural joint Bristol City Council – UWE Centre for Sustainable Planning and Environments (SPE) Symposium on Green and Blue Infrastructure took place at Bristol City Council’s Cash Hall on Monday 11th February. This provided an excellent opportunity for planners and researchers to come together to share policy and practice experience relating to the delivery of high-quality green infrastructure (GI).

First up was Bristol City Council’s Richard Goldthorpe, from the City Design Team. Richard focused on “Policy towards delivery” and highlighted some of the gaps and new developments in place-shaping policy. Richard introduced the need for a West of England Green Infrastructure Plan to bridge between the West of England Joint Spatial Plan (JSP) and the Bristol Local Plan. The JSP will set out a prospectus for sustainable growth to help the combined authority meet its housing and transport needs for the next 20 years, to 2036. He also emphasised the need for the Local Plan to link to the provision and design of specific parks and green spaces. Richard closed by emphasising the need for good research data to inform GI policy and delivery.

Next on the floor were Liz Kinsey (South Gloucestershire Council) and Kathy Derrick (Bristol City Council) who introduced “The Frome Reconnected” a collaborative project focusing on future-proofing the river Frome, involving Wessex Water, the Environment Agency, South Gloucestershire Council and Bristol City Council. They described the specific challenges facing the Frome and its catchment: urbanisation and an increase in impermeable surfaces increasing flood risk; diffuse pollution; heavily modified sections involving culverts and restrictive fish barriers and fragmented habitats. Possible positive strategies to address these challenges included river restoration to facilitate fish passage, with an increasing focus on health, recreation and the possibility of introducing green prescribing activities on the Frome.

Our own Associate Professor Danni Sinnett was the next to present the framework that underpins the RTPI award-winning “Building with Nature: a national benchmark for green infrastructure”. https://www.buildingwithnature.org.uk/. This was developed through a Knowledge Transfer Partnership with Gloucestershire Wildlife Trust funded by Innovate UK and the Natural Environment Research Council. Danni explained how developers’ and policymakers’ lack of understanding of the characteristics of high-quality GI had driven the development of the benchmark. She went forward to explain how the framework can be used to deliver high quality GI, setting out the core principles, (distinguishing a GI approach from a more conventional green space approach), and those focused on achieving benefits for health and well-being, water management and nature conservation. Danni highlighted specific case study projects including Elderberry Walk, awarded a Building with Nature Design Award for the entire Masterplan for 161 new homes on a brownfield site in Bristol, and Gloucester Services on the M5 motorway. The services (both N and S-bound) incorporate an outdoor picnic area, play facilities and habitat provision.

The final presentation by Dr Helen Hoyle (SPE) focused on co-producing urban meadows in green spaces with local authority land-managers in Bedfordshire. This was part of a larger Natural Environment Research Council-funded research project, Urban BESS http://bess-urban.group.shef.ac.uk/ (Biodiversity and Ecosystem Service Sustainability). Researchers from the University of Sheffield and Cranfield University introduced native perennial meadows of different floral content and heights to areas of amenity mown grassland in contrasting urban contexts in Luton and Bedford. This was done to gauge public reaction and invertebrate response to increasing biodiversity on the sites. Helen worked in the bridging role between researchers and practitioners on the ground and reported on research focusing on the land-manager perceptions of the challenges and opportunities of making such changes. https://www.sciencedirect.com/science/article/pii/S1618866716305489 Findings highlighted the key factors as: Economic resources; Aesthetics, or the appearance of the meadows, and specific Locational context. Land-managers were aware that introducing floral meadows could make some areas of green space much more attractive for the public. Nevertheless, disposing of meadow cuttings at the end of the growing season was expensive, currently ruling out the possibility of introducing meadows as a cheaper management approach than mown grass. They were also aware that although many people now accept messier urban planting, there were still those who prioritised tidiness directly outside the front of their homes.
