The environment and public health are managed by separate institutions that often operate in isolation from each other. This system is often referred to as managing in "silos." The resulting lack of coordination, inadequate consideration of cumulative effects, and diffuse targets for change contribute to the persistence of many environmental justice problems. There are many barriers to bridging these silos, particularly at state and federal levels. Local collaborations, however, may have greater potential for changing these systems. There has been limited assessment of successful local environmental health initiatives. This paper explores three case studies of local collaboration: lead poisoning prevention in Rochester, New York; promoting a healthy and equitable built environment in Duluth, Minnesota; and increasing consideration of community health in decisions around the ports of Los Angeles and Long Beach, California. It develops a research agenda to inform future collaborations to improve environmental health equity through local systems change.
