Early Warning Systems for Adaptation - Science for Adaptation Policy Brief #4

This policy brief outlines the role of Early Warning Systems for Adaptation in strengthening climate resilience amid increasing frequency and intensity of extreme and slow-onset climate events. It explains that integrating climate change adaptation into early warning systems enhances disaster risk reduction and supports sustainable development, particularly in Least Developed Countries and Small Island Developing States. The document presents a systems approach comprising risk knowledge, monitoring and warning systems, dissemination and communication, and preparedness and response capability. Drawing on global evidence and examples, it identifies data gaps, capacity constraints and financial disparities as key barriers. It emphasises transdisciplinary collaboration, integration of local knowledge, forecast-based early action, and targeted financing to strengthen implementation and expand coverage.
