This project will provide a novel citizen science approach to collecting and interpreting data about domestic gardens in order to co-develop an action plan with project partners to prioritise greening solutions within and beyond domestic gardens. Domestic gardens offer a valuable source of green infrastructure (GI) within an urban environment. They are important patches of greenspace that can provide connectivity between larger areas of GI (parks, recreation grounds etc), therefore improving the functioning of ecosystems and the services they provide, such as reducing surface water runoff thereby reducing flood risk, and lowering urban temperatures. While individually, a domestic garden may appear insignificant, collectively domestic gardens contribute up to 30% of greenspace within the urban matrix, which becomes especially important at the city scale. In spite of this, the quantity and quality of green infrastructure provision by domestic gardens is not well-evidenced. This has implications for the future resilience of an urban environment and the health and well-being of its citizens. Current data over-estimates the amount of vegetation within private gardens, which leads to subsequent inaccuracies in environmental model outputs (e.g. surface water runoff in an extreme rainfall event), and in the identification and prioritisation of areas of GI need, inhibiting effective action on-the-ground. Furthermore, the general public are often unaware of the environmental value of their own private garden and how they can improve it. This project will address these issues directly by: 1. Inviting city residents to complete an online survey about their own garden, the results of which will be amalgamated to create maps of domestic garden greenspace both in terms of quantity and quality. Survey respondents will be given a score for the environmental quality of their garden based on their responses to the survey, together with some information as to how their garden could be improved in relation to biodiversity, climate regulation and improving air quality. 2. Validating the survey responses using high resolution satellite data. The combination of the satellite data with the survey responses will be used to establish a classification scheme for different garden types, which can then be extrapolated to the wider city area. 3. Modelling how the vegetation within a domestic garden impacts surface runoff, temperature reduction and air quality. This will be done across multiple scales, from an individual garden to the neighbourhood-level and eventually at the city-scale. 4. Developing an action plan for GI solutions within the city based on the findings from the previous objectives and existing, larger-scale, green infrastructure datasets. Manchester is the test city for this project; the proposal has been developed in partnership with Manchester City Council, Red Rose Forest, Southway Housing, Lancashire Wildlife Trust and additional members of the Manchester a Certain Future Green Infrastructure Strategy Group (Environment Agency, BDP, Groundwork, National Trust). The project outputs will allow these end-users to develop a more robust plan for GI under current and future climate scenarios. Consequently, project outputs will contribute to enhancing the quality of life for the local population and to improving the resilience of the Manchester City environment. Further impact will occur at the individual level (improving individual gardens based on the survey feedback, strengthening community cohesion), neighbourhood-level (the evidence created can be used for biodiversity/GI/ES offsetting for new housing developments, housing associations will use the project outputs for improving neighbourhoods and access to green space) and stakeholder-level (private developers can use the outputs to add value to residential areas and development, third sector organisations can use the maps for developing policy recommendations and actions).

Green infrastructure (GI) delivers a range of crucial environmental processes and benefits to urban populations. GI also has the potential to play a key role in 'climate proofing' cities. Despite a wealth of scientific understanding on the importance of GI, the implementation and uptake of GI in new developments in the UK is lacking. Through a dialogue and exchange of knowledge with project partners from public, private and charity organisations, this project will develop and test a route map which translates GI scientific research into a practical and applicable user interface. Central to the development of the route map is the identification of user knowledge needs and an exploration of the current perceived barriers to GI uptake. The route map will facilitate the integration of GI science into user organisations, using Manchester as an exemplar city. Crucially, this project will also develop institutional embeddedness in project partners and other key stakeholders to utilise and apply GI science knowledge within user organisations. Through the co-production of knowledge, project partners will enhance their research literacy, thus enabling them to access, assess, translate and integrate GI science in the planning, design, delivery and funding of new developments in Manchester and beyond. It is envisaged that the approach implemented in this project will be adopted by other organisations and stakeholders, and in doing so, will help multifunctional GI-based solutions to become part of business-as-usual city growth in new developments.

Green and blue spaces (GI) can directly and indirectly influence human health and wellbeing. However, access to health and wellbeing benefits is not shared equally amongst the population, particularly in urban areas. Research shows that people aged 65 and over are most likely to suffer from poor health, yet this group may be the least likely to benefit from GI. Although good health and wellbeing in an ageing population might be promoted through access to GI, using GI may not always be beneficial particularly as older people can be more susceptible to environmental stressors. Understanding how GI is valued in the context of the health and wellbeing of older people is one such unknown. This value might include the monetary value of preventing ill-health but also broader interpretations, such as the historical, heritage or wildlife value that influences whether older people actively seek experiences in green and blue spaces. The GHIA research project; 'Green Infrastructure and the Health and Wellbeing Influences on an Ageing Population' aims to better understand the benefits and values of urban GI for older people and how GI and specific 'greening projects' can be best used to support healthy ageing in urban areas. The proposed case-study area is Greater Manchester (GM). GM is the first northern city to adopt a devolutionary settlement including control of health and social care spending. The research team are partnering with organisations involved in improving the health and wellbeing of older people and the design and management of GI across GM, including GM's Red Rose Forest, Public Health Manchester, Manchester City Council and Manchester Arts and Galleries Partnership. A core part of the research will look at how the research findings can be translated into policy and practice and the transferability of findings to other cities, potentially with similarly devolved powers. It will do this by involving older people as 'co-producers' of the research to better understand thoughts, experiences and values that are associated with green and blue spaces. This will have a particular arts focus, including storytelling, sensory engagement and offering new experiences for engaging with green and blue spaces. Different types of urban GI will be used, including green 'patches' within the city (e.g. urban parks), green and blue 'corridors' (e.g. canals and waterways) and green spaces within the wider urban fabric or 'matrix' (e.g. private gardens). This co-production of research findings will be linked to all the other areas of work undertaken in the project. Other aspects of research will be conducted on the potential benefits and disbenefits of green spaces on ageing health and wellbeing and the value that this provides. This will include looking for relationships between health data and the occurrence of GI across space, 'before and after studies' exploring the influence that different greening projects have on the physical activity of older people, measuring how GI may affect older people's exposure to environmental hazards (such as air pollution and extreme temperature) and working with people with early-onset dementia to understand how they appreciate the urban landscape through different 'sensory' perceptions. The findings from the other components of the research will then be used to explore the values applied to the GI benefits and how these can help guide policy and practice. This will include evaluating existing measures of valuing greenspace, including monetary valuation and then work with older people to understand broader interpretations of value, such as culture, heritage, history and the natural or 'biodiversity' value. These findings will be used to develop online mapping tools that demonstrate the needs, provision and value of GI for older people. The team will then work to explore how these findings relate to other locations and communicate findings to urban areas across the UK.
