Cardiff researchers in project to make cities 'greener'
Cardiff University has been awarded one of 14 research grants to develop 'green infrastructure' in urban areas around the world.
Urban forestry is one example in which woodland is planted in cities to manage storm water and reduce city temperatures.
Another example is ‘green roofing’, whereby roofs are partially or completely covered in vegetation to absorb rainwater, increase insulation and, again, reduce the temperature in cities to combat the so called ‘heat island effect’.
