Improving Blue and Green Infrastructure to Counteract Increasing Urban Temperatures

by Deniz Korman

Urban areas experience higher temperatures compared to rural areas, and it is likely that this will lead to health risks within urban communities due extreme heat in the future. However, we have the power to minimize this effect by improving the infrastructures of our cities. An effective way to lower urban temperatures is increasing vegetation and water surfaces, which also provides the added benefit of increasing urban biodiversity, and improving air quality. While this known to be a valid strategy, the magnitude of the climate impact that such an improvement will have when applied on a city scale is unknown. Žuvela-Aloise et al. (2016) have modeled the potential of improving green and blue infrastructure within Vienna, and identified the ways in which changes should be applied in order to counteract urban warming as effectively as possible.
