Integrated Green Grey Infrastructure Framework Accelerator

Lead Research Organisation: University of Glasgow
Department Name: School of Geographical & Earth Sciences

Abstract

Green infrastructure is a term used to describe the elements of the natural environment we see in our towns and cities - traditional grass, trees, flower beds and parks but also more innovative elements like green roofs and green walls.
The IGGIframe project examined around 40 innovative techniques to include green infrastructure on "grey" (non-building) infrastructure that needs to remain primarily grey. These examples are not normally included in green infrastructure policy and practice - our project addressed this gap. For example, sea walls are typically made of smooth concrete, but by casting them to have some texture, e.g. to mimic natural stone, they can provide habitat for barnacles and other species, which can in the case of barnacles, also protect the concrete from damage, helping to extend the design life of coastal structures.

The IGGIFrame project developed a framework to determine how well these examples worked, and how much they cost compared to traditional 'business as usual' grey options such as a smooth sea wall. This created a clear benefits assessment and financial basis for choosing a green grey solutions compared to conventional grey options. This project was co-produced by key government and industry partners across the UK and is designed to support others who want to implement these green infrastructure innovations.

Whilst the IGGIframe project was co-produced, there was limited time for testing and embedding the tool in partner organisations beyond their assistance with designing the tool. Partner organisations have also requested additional materials to support implementation within their organisations (e.g. Evidence Summaries requested by Natural Resources Wales). The follow-on funding would allow us further test and embed the tool within 5 different organisation. This would also allow us to examine how consideration of IGGI and IGGIframe could be included in how the organisations make decisions, and then to create a strategic plan - a road map, to help them include green grey infrastructure in the future.

The process of embedding would be iterative and allow us to develop an improved, tested version of IGGIframe with clear testimonials of how it has been used by partner organisations. This improved version would then be hosted on a website (e.g. http://www.oppla.eu/marketplace) where other people such as engineers, local authorities and consultants could upload the details of their scheme for others to learn from, support and contribute to. This would create a living inventory of IGGI examples that practitioners could draw on.

Planned Impact

This proposal is for innovation follow-on funding, to provide support for follow-up activities from a NERC Green Infrastructure Innovation funded project. Knowledge exchange and activities to generate impact are thus integral to the scope of work described in the case for support. In the pathways to impact section we described specifically how we intend to accelerate and evaluate the quality and reach of impact arising from this follow-on funding for the five partner organisations. The key impacts that could potentially arise from this work include increased awareness and application of Green Grey infrastructure approaches (which we call IGGI, short for Integrated Green Grey Infrastructure) in policy and day to day practice of the five partner organisations. This will help them delver their statutory requirements for green infrastructure and biodiversity, and as these IGGI approaches are applied it will lead to improved health and wellbeing of cities and nature in our cities and towns.

We will also seek to extend potential impacts of our IGGIframe follow-on activities to the project advisory board members and via information exchange platforms hosted by them (e.g.) or third parties (e.g. Oppla, the Ecosystems Knowledge Network or the Landscape Institute). We have also been invited by the Editor to produce an article for the Environmental Journal. It aims to bridge "the gap between those who are developing solutions to pressing issues ranging from pollution to greener transport and practitioners tasked with putting ideas into practice," Environment Journal (2017). Two key online platforms would also host the outputs: Oppla and CIRIA, where webinars would be arranged to raise awareness of these outputs and to provide continuing professional development training. Both web platforms are needed as they reach different audiences, with CIRIA being more aligned with the construction industry and Oppla being favoured by local authorities and NGOs. We would use these articles, webinars and training sessions, along with key networks (e.g. CIRIA's, Central Scotland Green Network, Green Infrastructure Partnership, Linear Infrastructure Network (LINet)), to share the results of the IGGIframe project and to generate enthusiasm and input to the Oppla living library of IGGI best practice case studies.

More widely, the general public will be engaged about the proposed project as part of the Edinburgh Living Landscapes exhibition in 2018. A recent NERC funded Public Engagement pilot project funded the installation of two Vertipools which are also a coastal case study in the IGGIframe project. This event will provide an excellent platform for engaging the general public about coastal IGGI and the IGGIframe project more generally.

Description This project is an innovation follow-on project designed to help embed results of Phase 1 of the project within organisations in terms of their policy and practice, as well as to extend the reach to other organisations and interested parties, to heighten awareness of this work.
Exploitation Route There is already demonstrable evidence (see policy/practice influence) of how the 'Greening the Grey'/'Integrated Green Grey Infrastructure' project's outputs is being used to shape policy and practice across England, Wales and Scotland of government agencies, local authorities and private sector organisations. This firmly demonstrates the value of the time to embed the results of the NERC GI innovation project into practice. The project is still live and it is anticipated that further benefits will be realised during 2019-2020.

Description The findings from the 'Greening the Grey'/'Integrated Green Grey Infrastructure' NERC Green Infrastructure Innovation project have been used by a number of partner organisations to help influence policy and practice changes within these organisations. This includes reference to the concept/report within draft statutory policies in Wales and Scotland, inclusion in Best Practice Guidance (Natural England) and directly shaping practice in live coastal flood alleviation schemes in England and Scotland. In addition, more than 450 people have been trained in the concept via webinars and training sessions and over 43000 people attended an exhibition on Edinburgh's shoreline where the greening the grey concept and examples of applications of this concept along Edinburgh's shoreline were featured.

Impact Developing the first ecoformliner design for a live coastal construction scheme with Portsmouth City council. UK-wide government agency interest in ecological net gain and enhancing hard coastal infrastructure is rapidly growing and designing an ecoformliner for the Portsmouth scheme would help close the gap between policy goals and practical implementation, with a product specifically designed to support UK ecology and cultural/aesthetic norms. This formliner is the first known to be designed based on UK science with the goal of improving habitat provision for intertidal species compared to a traditional plain cast concrete engineering design, which can also help provide some accommodation space for species affected by sea level rise. This design has been included in the tender brief for the construction phase of the project, the first known UK flood scheme to specify a formliner specifically designed to enhance ecology for a vertical seawall.

Geographic Reach Local/Municipal/Regional 
Policy Influence Type Influenced training of practitioners or researchers
Impact North Ayrshire Council has listed IGGI /Greening the Grey as one of the environmental options being considered to help enhance the ecosystem services value of a planned flood alleviation scheme. This is being included at the options appraisal phase of the scheme's planning and design processes. It builds on the work of my student's PhD examining the interrelationships between geodiversity and biodiversty (funded by the Marine Alliance for Science and Technology and the University of Glasgow, which North Ayrshire Council provided logistical support for) and directly links to two of the examples in the IGGI report (AP-C7 and AP-C8). The main impact to date has been a change in practice to include consideration of ecological enhancements as part of the options appraisal process. If IGGI principles and techniques are used in the design for planned scheme there will likely be a mitigation of some construction impacts on ecology as new habitat will be created if implemented. It also has the potential to deliver net ecological gain. These impacts have yet to be realised but the inclusion in the options appraisal phase is promising.

Results and Impact Edinburgh Living Landscapes/City of Edinburgh has showcased Greening the Grey and Coastal Climate Change adaptation in a public exhibition running from June - October 2018; this is being evaluated by their project. 43,065 people saw the exhibition . The ideas presented in the exhibition resulted in 48/51 participants having a slightly improved or improved understanding of the cultural and environmental significance of Edinburgh as a coastal city. Of those surveyed, 92.16% had some degree of improvement in their understanding of coastal climate change and 80.40% stated they would 'certainly' think differently about how coastal climate change would impact Edinburgh after the exhibition. In addition, by raising awareness of the value and risks to Edinburgh as a coastal city, participants said they were likely to visit the shoreline as a result of the exhibition (45.10%) in addition to those who already visit the shoreline regularly (29.41%) and stated that they were either possibly (43.14%) or certainly (50.98%) more likely to actively work on protecting the Edinburgh shoreline as a result of the exhibition. Those surveyed were across a varied age range from under 16 to over 65 and the majority lived within Edinburgh, highlighting this exhibition's success increasing awareness in understanding the value of Edinburgh's shoreline.
