Tool Developed To Value Health Of Urban Developments
A new tool to value the health effects of urban development proposals has been revealed by researchers at the Universities of Bath and Bristol and published in Frontiers in Public Health.
The valuation tool evaluates a range of factors including how buildings, transport, natural environment (including air pollution and green space), socio-economics and community infrastructure in new developments might improve or worsen health for its future residents.
By integrating environmental economics with public health systematic reviews and urban design analysis, researchers were able to value the potential health effects that may result from development proposals and provide evidence to assess the health costs of urban planning decisions.
The tool, which sub-divides the urban environment in to 28 characterisations, places a value not just on air pollution, which is most commonly evidenced, but also on a range of factors which could lead to premature death and chronic morbidity, profoundly affecting quality of life and the cost of healthcare.
The work forms a core part of TRUUD, a major transdisciplinary research project which aims to reduce non-communicable disease (such as cancers, diabetes, obesity, mental ill-health and respiratory illness) and health inequalities linked to urban planning and development.
For instance, green spaces provide a range of health benefits, especially for adults in reducing diabetes and risk of weight gain. However, green spaces can also contribute to childhood asthma. Similarly, a significant link was revealed between noise from traffic and child conduct disorder (and the cost of treatment medically). By adjusting scenarios planners could have a tool for measuring the likely health impacts of increasing or decreasing the amount and quality of green spaces.
University of Bath researcher Eleanor Eaton and lead author of the paper commented: “It is possible to value the potential health effects of our urban environments and weigh these against the traditional financial costs and benefits of city development.
“We still have some health impacts such as mental health and chronic pain where the evidence is incomplete where further research will help create a full picture for planners and policy makers.”
