Today we're discussing the impact of urban green spaces. A recent study in Melbourne found that parks can reduce local temperatures by up to 4 degrees Celsius during heatwaves. However, the effect depends on the size and density of trees. Larger parks with mature trees have a more significant cooling effect than small grassy areas. Interestingly, the study also noted that the presence of water features, like ponds, enhances cooling, but only when combined with shade. The researchers suggest that city planners should prioritize planting native species, as they require less water and support local biodiversity.
