Population, health, environment (PHE) practitioners, researchers, and advocates utilize communications, outreach, and advocacy to increase policymakers’, development practitioners’, educators’, and other decision-makers’ knowledge about and awareness of complex PHE linkages. This occurs through outreach at conferences and events; publication and dissemination of research, lessons learned, and best practices; and outreach and training with journalists. As journalists and developing country champions of PHE communicate the results of PHE efforts to priority audiences, they are contributing at multiple scales to policy discussions and policy making that supports the integration of PHE. This section includes examples of communications strategies, tools, and messages that have been used in these efforts.
