A cross-species perspective on migration in the Anthropocene

Migration, whether of trees, animals or humans, is a universal ecological response to environmental change. Yet scientific and policy frameworks treat these processes in isolation, obscuring their shared temporal structure and coupled dynamics. Reframing migration as a temporally layered, cross-species phenomenon enables more coherent climate governance, more equitable policy, and more effective conservation across taxa, sectors, and regions. This reframing must, however, be grounded in legal authority to act.
