Early Warning Systems: A State of the Art Analysis and Future Directions

This report gives an overview and analysis of early warning technologies and capacities in the developing world, including the basic concepts of early warning systems and the role of earth observation for disasters and the environment. While focusing on existing systems, it also addresses gaps in monitoring, communication and response that need to be filled to improve timely decision-making for slow-onset emergencies.

The authors highlight that much more needs to be done before a global multi-hazard system can be developed. Recommendations for filling operation gaps include: improving existing technologies and systems; building infrastructure and capacities in developing countries most at risk; and bridging science and decision making.
