In today's lecture, we'll discuss the impact of urban green spaces. Recent studies show that parks and community gardens can reduce local temperatures by up to 5 degrees Celsius during heatwaves. Additionally, they improve air quality by absorbing pollutants. However, the key factor for maximizing these benefits is not the size of the space, but its distribution across the city. For instance, small pocket parks scattered throughout neighborhoods are more effective than one large central park. This is because they provide easier access for residents, encouraging more frequent use and physical activity. Therefore, urban planners should prioritize creating a network of small green areas.
