Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that increasing tree canopy coverage by just 10% can reduce local temperatures by up to 2.5 degrees Celsius during summer heatwaves. This happens because trees provide shade and release moisture through transpiration. However, the researchers noted that the effect is strongest in residential areas with low-rise buildings, rather than in city centers with tall structures that block air flow. The study also highlighted that parks with diverse native plant species attract more pollinators, which benefits nearby community gardens. So, when planning new housing developments, incorporating green corridors is crucial for both climate resilience and biodiversity.
