This project aims to maximise the policy impact of research already undertaken on walkability, particularly the development of a Real Walkability Network, which has initially been generated as part of the PARC project based on a study area of East Belfast. This project aims to extend the applicability of the developed policy tools to cover the two main cities of Northern Ireland, Belfast and Derry, so that the model then covers 37% of the population and some of the most deprived communities in the region. The project will disseminate the use of this model to practitioners in order to increase the evidence base for interventions in the built environment aimed at promoting physical activity. It will provide a range of benefits for both the academic community and the end users of research. For academics, it will make important contributions to ongoing research on understanding the environmental correlates of physical activity and through engagement with practitioner communities will aim to create a virtuous circle of research, implementation and feedback. For end users it will provide benefits in terms of the establishment of a useful decision-making tool that will enhance the evidence base for environmental interventions for improving physical activity and will provide training and capacity building in its use with the aim of establishing sustainability for its ongoing deployment. The value of the project is reflected in the large number of public bodies that have been willing to become partners, including Belfast and Derry City Councils, Department of Regional Development, Dept of Health Social Services and Public Safety, Public Health Agency and Belfast Healthy Cities, as well as cities in England, who have provided match funding and in kind support of over £88,000. The project will run for 12 months and employ two research assistants to help undertake three separate work packages: Work Package 1: Model consolidation and validation. (Months 1-5) This work package will involve the appointment, training and placement of 2 research assistants to be based in Belfast and Derry City Councils respectively, during which time they will consolidate and extend the model developed for East Belfast so that it has operational coverage of the entire 2 local authority areas. The model will be subject to validation using random checking of critical elements, such as land use and footpath coverage. During this time the research assistants will interact with staff of local authorities and other statutory agencies to begin to build up an understanding of the extent, form and availability of spatial data and the information needs of different partners, including potential links to regional strategies on obesity, active travel and physical activity. Work Package 2: Project integration and sustainability (Months 6-10). Work package 2 will involve a process of integrating the walkability models and other elements of spatial analysis into the existing physical activity-related programmes of the partner organisations to improve their effectiveness, efficiency and accuracy. This stage of the project will also involve developing the capacity of project partners to ensure the sustainability of the place-specific walkability models. Work Package 3: Knowledge dissemination and engagement with wider practitioner communities (Months 11-12) Work Package 3 will involve an evaluation and a report of the benefits, costs and opportunities arising from the operational deployment of walkability models and their integration with other central and local government responsibilities and initiatives. On the basis of this evaluation, a series of workshops will be run in Northern Ireland and the UK. Finally, the findings of the project will be presented at three conferences to disseminate the findings to different academic and practitioner communities.

The number of people worldwide living with dementia and cognitive impairment is increasing, mainly due to people living longer, so we want to figure out how where we live affects dementia and brain health as we get older. Some research suggests that where we live might influence our brain health. For example, poor air quality in towns and cities, can lead to a decline in brain health. As more of us now live in towns and cities, it is important that the environment where we live is scientifically designed and improved to maximise our brain health. The complex social and physical environments where we live make some people more vulnerable than others to developing cognitive impairment. In other words, the factors that account for who is most likely to develop cognitive ill-health due to the environment has less to do with 'how' we live and more to do with 'where' we live. We do not know how these factors interact to make urban environments a problem for brain health, nor which are the best policies and interventions for promoting healthy ageing and brain health for our poorest communities. Our project will provide evidence for policies and practices that provide supportive urban environments to promote healthy ageing, including promoting brain health. This could include using creative urban designs to support people to adopt and maintain healthier lifestyles such as being more active. However, this needs a strong evidence base with expert community advocates who can articulate how supportive urban environments can improve brain health. Our research has the following steps: 1. First, with the help of stakeholders, including those from business, industry, and local government, and a review of existing research, we will represent the relationships between our biology, our lifestyles and our environment in a diagram illustrating how they likely interact to affect brain health, because visual thinking can help stakeholders better identify possible intervention sweet-spots to improve brain health. 2. By analysing data from over 8,000 older people in Northern Ireland, and linking this to information about where they live, such as the amount of air pollution, the toxins in soil, or how walkable their neighbourhoods are, we will explore how different environmental factors relate to brain health. 3. Next, we will collect new data on a subgroup of 1,000 older people including more in-depth measures of brain health and better measures of physical activity, using GPS devices worn around the waist that monitor our locations. This will allow us to explore how the urban environment influences our brain health. 4. Then, we will explore how aspects of our biology play a role in how the urban environment affects our brain health. 5. We will host workshops with local citizens to 'sense-check' our findings and co-develop promising prevention approaches. In these, we will explore the acceptability, affordability, feasibility and sustainability of new initiatives to improve the environmental influences on brain health. This might include, for example, policies on: expanding the car-free areas of the city to reduce air pollution; increasing the number of footpaths and cycle paths to encourage walking and cycling; improving public transport to reduce car use. As a result of our research we will produce: 1. A map of the system in which our genes, lifestyle behaviours and urban environments interact to affect brain health, to help guide stakeholders towards policies and programmes that can improve brain health. 2. An evidence base exploring how where we live affects our brain health. 3. A suite of potential policies and interventions to improve brain health and promote healthy ageing 'tested' (in terms of acceptability and feasibility) with older people, business, industry, policymakers and other stakeholders.
