In fragile and conflict-affected settings, humanitarian actors often operate without access to the data, tools, and science needed to anticipate and respond to climate shocks. This interactive session brings together researchers, humanitarians, and local voices to explore how applied climate and water science—including digital twins, anticipatory action tools, and community-driven analytics— can improve aid timing, impact, and resilience. Through demos and discussion, the session will spotlight tested solutions, scalable innovations, and successful partnerships from the field.
