Climate change is increasingly seen as a threat multiplier, posing key challenges to the planetary environment and security. It acts as a stressor on human security, which is influenced by conflict risk, fragility, internal and transboundary migration, energy security and other sectoral security issues, including food, water and biodiversity security, among others. In a highly context-specific manner, these diverse issues have a negative impact on the livelihoods and social cohesion of communities, thereby contributing to wider destabilization within countries and regions.

Situated at the intersection of humanitarian, peacebuilding and development work, actions within the nexus of security, climate change and the environment need to be informed by an enhanced understanding of overlaps, synergies, and trade-offs as well as approaches for geographically inclusive and cross-sectoral resilience building. To identify evidence-based approaches and strategic actions on the climate-security nexus, it is important to enhance the understanding of key issues, interlinkages, and actors, as well as relevant multilateral and regional processes and frameworks. Principal areas to address include the impacts of approaches for climate resilience-building on security; the impacts of security measures on climate policy and action; and questions on effective policy measures, financing, means of implementation, bridging of silos, and transboundary collaboration.
