Knowledge Gaps in the Nexus of Climate, Peace and Security

There is a growing body of research on the relationship between climate change and peace and security. Research shows that the effects of climate change can exacerbate existing vulnerabilities, such as food and water security, and in combination with other factors can also increase the risk of violent conflict. It is increasingly recognized that actions taken to prevent and manage conflict can be coordinated and integrated with actions to mitigate and adapt to climate change. Such cross-disciplinary cooperation can generate outcomes that are beneficial for both a sustainable peace and environment. The COP27 Presidency initiative titled “Climate Responses for Sustaining Peace” (CRSP), has taken a leading role in this movement by spearheading a discursive pivot from a climate security nexus towards a climate and peacebuilding nexus, with multifaceted and holistic approaches.

The literature on how to integrate climate adaption and mitigation actions in efforts to build sustainable peace is still underdeveloped. However, there are related fields, such as the relationship between peace, conflict and natural resource management that may offer comparable lessons. This policy paper takes stock of the existing knowledge and identifies knowledge gaps for policy practice in the crucial, complex and emergent field of climate, peace and security. It classifies significant gaps in our actionable knowledge by sorting them into operational knowledge gaps, climate finance knowledge gaps, and gaps in the knowledge infrastructure.
