Today, in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that adding more parks and trees can reduce city temperatures by up to 2 degrees Celsius during heatwaves. However, the researchers noted that the location of these spaces is crucial. For example, shaded areas near buildings provide the most significant cooling effect, while isolated trees in open parking lots have minimal impact. Additionally, green roofs, though more costly to install, offer dual benefits: they insulate buildings and absorb rainwater. The study suggests that city planners should prioritize small, strategically placed green areas over a few large parks, as they benefit more residents and improve air quality in densely populated neighborhoods.
