Ecosystem services—the physical processes performed by soils within an ecosystem—are well-known in agricultural settings, but how do we define and measure them in urban settings? Join Dr. Sara Acevedo, assistant professor at La Pontifícia Universidad Católica de Chile, as she explores what it takes to measure the metals and other contaminants left in soil by human activity, the effect of soil homogeneity in an urban landscape, and to extend these studies out into areas of human development that have been ravaged by wildfires.
