Vacant lots comprise more than one-fifth of the land area in most post-industrial U.S. cities. For residents in those neighborhoods, the lots function as breeding grounds for pests, provide a haven for illegal activities, and attract litter and illegal dumping—all of which degrade the quality of life for residents and lower the property values in that community.

The Pennsylvania Horticultural Society (PHS) has implemented a pioneering solution to renew vacant urban lots. Their Philadelphia LandCare program transforms city neighborhoods by “cleaning and greening” neglected and vacant lots.
