In an era of escalating environmental and geopolitical challenges, understanding and addressing the intersection between climate change and security has never been more urgent. The nexus between climate impacts and a wide range of security dimensions—spanning from human mobility and food systems to governance and conflict—demands nuanced, context-specific, and multi-sectoral responses. This scoping paper by SLYCAN Trust offers a foundational step towards unpacking the complex and evolving relationship between climate change and security. Through mapping key thematic areas and highlighting existing gaps, it aims to inform policy processes, foster collaboration across disciplines, and support the development of integrated, inclusive, and forward-looking approaches that respond to both immediate and long-term risks.
