This multidisciplinary project aims to understand how urban design influenced by historical and heritage data can be used to address issues such as environmental sustainability, public health, and ethic/religious/class segregation in cities. The research brings a team of academic investigators (history, architecture, peace and conflict studies) together with local government officials (planning, environment, museums and heritage service) and social enterprise (design, digital fabrication) to collect a wide array of data that will then be used to aid the design of a multi-million pound public landscaping project in the city of Derry/Londonderry. Research by the World Heart Federation (Smith et al, 2012) has established a strong link between urbanisation and cardiovascular disease, while also identifying urban design as an essential pillar in its recommendations for improving public health in cities. In particular, the engaged development of infrastructure, parks and green corridors were outlined as an essential part of a strategy to improve public health along with public information campaigns, access to healthcare, and stakeholder engagement. Working from the premise that urban design can contribute to not only an improvement in public health, but also to environmental sustainability and community cohesion in divided cities, the project intends to build a bank of historical and heritage data that can be used to ensure that future urban design projects will reflect the cultural and architectural heritage of the area under development. In so doing, the community ownership and use of such projects and facilities can be increased through the formation of a partnership between academic researchers, local government officials, community activists, and residents. The city of Derry/Londonderry has a history of violent division stretching back hundreds of years and urban design has been at the centre of attempts to both divide and integrate from the erection of the city walls in the seventeenth century to the construction of the pedestrian Peace Bridge linking the unionist east to the nationalist west of the city in 2011. The project combines methods from history and historical anthropology (oral history interviews, archival and statistical research), geography (GIS mapping), design (digital fabrication), and the wider social sciences (walking interviews) to collate data relating to space and place, and how people have interacted with a changing built environment over time in a divided city with a violent past. Borrowing from the thinking behind the emerging discipline of design anthropology, in which ethnographic engagement leads to better design solutions for products and services, the research attempts to harness history, cultural/architectural heritage and social memory to help provide urban design solutions that are more reflective of people and their often dearly held personal and environmental histories. An official partnership between the project investigators and Derry City and Strabane District Council will result in the research data being used to inform large-scale landscape and urban design projects to be developed during the lifetime of the research project as part of the Northern Ireland Executive's Urban Villages scheme. A similar partnership with the Nerve Centre FabLab (a community based digital fabrication centre) will result in the grassroots production of 3D city model plans that will be exhibited in the Tower Museum and be further used to inform the projects due to be developed in the city in the coming years. The project will also contribute to the developing historiography of the Troubles through the production of a co-authored book and journal articles on the history of how people in the city of Derry/Londonderry interacted with their built and environmental surroundings before and since the implementation of the Londonderry Development Plan (1968) and the onset of violence at the same time.
