GEO and UNFCCC Technology Committee have been co-producing a policy brief on technology and innovation for the [Early Warnings for All (EW4All) Initiative] (https://earlywarningsforall.org/). It highlights roles of technology with strong emphasis on Earth observations, in support of risk-informed climate and disaster resilience policy and action. The emerging findings include the fundamental value of risk information, especially exposure and vulnerability. For example, flood risk maps can visualize exposed areas with critical infrastructures, population, economic activities and ecosystems which have been frequently flooded and/or projected to be flooded more in the future, including due to climate change. The maps can also indicate what makes the exposed areas vulnerable, for instance, the high concentration of the aged populations, old buildings, endangered spices. Such climate information and disaster risk knowledge provide the basis for not only early warning system but also any infrastructure investment.
