The Tucson Million Trees initiative uses a two-pronged approach. First, it is science-based, planting desert, shade, and drought tolerant trees and utilizing stormwater harvesting infrastructure whenever possible to capture, retain, and filter stormwater to irrigate and sustain desert shade trees. Second, it is people-centered ensuring that heat vulnerable communities are prioritized and included in the planning and planting of new trees. It focuses on creating green jobs, especially for underserved youth leaders.
This approach will result in a healthy urban forest that helps mitigate the effects of climate change, including the urban heat island effect, while creating green jobs for young environmental stewards.
