Nearby rural land may significantly reduce urban temperatures
A recent study finds that rural areas around cities can lower urban temperatures by nearly 33 degrees Fahrenheit, suggesting a new approach to combating urban heat.
In short:
- Researchers studied data from 30 Chinese cities and found that rural land within a six- to nine-mile radius can reduce urban heat island intensity by about 30%.
- Urban heat islands occur when cities are warmer than their surroundings due to air warming, creating low-pressure zones that pull cooler air from nearby rural areas.
- The study suggests cooling strategies, such as planting woodlands and consolidating water bodies in rural areas, to boost urban cooling.
Why this matters:
Urban heat islands contribute to higher energy costs and health risks. By optimizing rural land use, cities can become cooler and more sustainable, benefiting both urban and rural communities.
