Papua New Guinea is at a pivotal moment, facing the converging threats of climate change, environmental degradation and persistent insecurity. As one of the world's most ecologically and culturally diverse nations, PNG's communities are deeply connected to their environments. Yet this interdependence makes them particularly vulnerable to climate- and environment-related shocks and cascading risks. The Climate, Peace, and Security Assessment, led by adelphi in partnership with ADB and UNDP, reveals that climate change is not simply an environmental challenge, but a force that is reshaping the landscape of conflict, vulnerability and development across the country. 

The assessment identifies:

  • 6 climate and environmental security pathways
  • regional dynamics and lessons
  • 8 priority recommendation areas
