Green Spaces In Cities Can Provide Beneficial Cooling Effects

The valuable cooling effects of large urban green spaces has been established; now scientists have studied small and medium sized parks in London to determine the optimum size, distribution and composition of urban green spaces needed to achieve urban cooling.

The valuable cooling effects of large urban green spaces has been established; now scientists from Forest Research, the research agency of the Forestry Commission, have studied small and medium sized parks in London to determine the optimum size, distribution and composition of urban green spaces needed to achieve urban cooling.

Built up urban environments can be as much as 9°C warmer than the surrounding area with buildings, road traffic and human activities all contributing to the 'urban heat island' effect. Vegetation, especially trees, has a crucial role to play in lowering temperatures by providing shade, reflecting sunlight and by evaporation.
