In contrast to the effect of changes in natural land use, urbanization is an important yet less studied aspect of anthropogenic land use change in climate science (Oleson, 2010). At present, approximately 50% of the global population reside within urban areas, and by the 2030s it may be 60% (UN Department of Economic and Social Affairs, 2007). Projections of large-scale or regional climate change rarely account for local drivers of change such as those from urbanisation, a potential effect that human populations will feel in a direct way. Urbanization has profound influences on the atmosphere, hydrosphere and biosphere which manifest in many biophysical characteristics such as exacerbated temperatures, reduced evapotranspiration, modified urban water flows (increased stormwater runoff and pulse driven aquatic systems), and reduced vegetation. This has impacts of reduced biodiversity, increased drying and increased water and energy. Moreover, urbanization is linked to hazards such as poor air quality and exacerbated heat related illnesses including heart disease/mortality, particularly during summer and heat wave episodes (Luber and Mcgeehin, 2008).
