Paving Paradise: The Heat Island Effect & High Cost of Underutilized Asphalt
Asphalt and concrete. Not exactly the sexiest topics in the world, but think about it: pavement is everywhere we look. From roads and highways to schoolyards and massive parking lots, it’s such a ubiquitous part of our environment that we hardly even notice it anymore.
And there’s a reason for that. Pavement makes roads safer and provides ADA accessible sidewalks. But it also comes with a significant environmental cost. Dark asphalt can absorb as much as 80 to 95 percent of sunlight, contributing to the urban heat island effect and making our cities (and the people who live in them) hotter and more vulnerable as the climate warms.
That’s why we’re excited to speak with Malena Marvin, Executive Director of Depave, a Portland, Oregon-based grassroots organization that works with communities to remove underutilized pavement and replace it with permeable, living green spaces. For example, an empty parking lot can become a public gathering space filled with trees and native plants, or a place where rain can return to the soil instead of rushing into storm drains.
Depave’s work is especially powerful because it connects environmental restoration with community health and agency, climate resilience, and environmental justice.
