Integrated population-health-environment (PHE) development programs can often produce greater improvements—at lower total cost—than multiple programs that each target only one sector. ECSP Director Geoff Dabelko recently interviewed Lori Hunter, an associate professor of sociology and environmental studies at the University of Colorado, Boulder, about her work evaluating integrated PHE programs with colleague John Pielemeier. In the following ECSP podcast, Hunter discusses the challenges associated with encouraging men’s involvement in family planning, implementing integrated development projects on the ground, and designing projects that are sensitive to local residents’ livelihoods and other priority needs.
