Today, in our environmental science lecture, we're discussing the impact of urban farming. A recent study in Chicago found that community gardens can reduce local temperatures by up to 2 degrees Celsius during summer heatwaves. This is because plants release moisture, which cools the air. However, the study also noted that the cooling effect is limited to a radius of about 50 meters from the garden. So, while city planners are keen on promoting rooftop gardens, they must consider the spatial distribution to maximize benefits. Interestingly, the study showed that gardens with a mix of trees and vegetables had a greater cooling impact than those with only vegetables.
