Interest in the intersections of environmental issues, peace and conflict has surged in recent years. Research on the topic has developed along separate research streams, which broadened the knowledge base considerably, but hardly interact across disciplinary, methodological, epistemological and ontological silos. Our forum addresses this gap by bringing into conversation six research streams on the environment, peace and conflict: environmental change and human security, climate change and armed conflict, environmental peacebuilding, political ecology, securitisation of the environment, and decolonizing environmental security. For each research stream, we outline core findings, potentials for mutual enrichment with other streams, and prospects for future research.
