Add water pollution to the list of ills suffered by under-served urban communities. Economically-depressed neighborhoods are hotspots for water contamination due to aging sewer and storm-water systems. Optimistically, a new study suggests that water cleaning and community greening can go hand-in-hand.
Projects that improve water quality by planting vacant lots, parking strips, and other urban spaces with trees and community gardens also bring people out of doors and teach local kids about their environment.
Ecologists define an ecosystem as a unit of the landscape—a forest, a lake, or a river. Often, they are interested in the movement of materials through that area. Rain may deposit nitrogen in a forest, while a stream may carry nitrogen away from the forest and into a river.
As the Director of the Baltimore Ecosystem Study (BES), a Long Term Ecological Research project, I work with colleagues to reveal how watersheds can be used to understand interactions among social, biophysical, and built environments.
