Public Urban Open Space and Human Thermal Comfort: The Implications of Alternative Climate Change and Socio-economic Scenarios

Climate change adaptation presents particular challenges in urban areas, where historic and current investment in fixed stock and infrastructure might constrain adaptation. This paper explores how two elements of adaptive capacity—building that capacity and delivering adaptation actions—are likely to be constrained by wider social and economic factors affecting urban societies. Public open space in urban areas, although having a vital role to play under conditions of climate change, is already a contested policy area. Using the field of outdoor thermal comfort as an example of current adaptive behaviour, the paper reports on a study that examined the perceptions of thermal comfort of different users of public spaces in Manchester. It considers the implications of climate change scenarios for the ability to maintain thermal comfort in open spaces and examines the scope for physical intervention, such as through urban and built form design, to build adaptive capacity. However, it also explores possible scenarios of urban life under conditions of climate change and concludes that socio-economic determinants of access to and management of open space are likely to be of critical significance in delivering adaptation options, which are accessible to all and meet objectives of social justice.
