In order to contribute especially to the achievement of Target (g) of the Sendai Framework, several international and regional organizations as well as national institutions with a key role in early warning joined forces and established the International Network for Multi-Hazard Early Warning Systems (IN-MHEWS) during the WCDRR in March 2015. IN-MHEWS aims to facilitate the sharing of expertise and good practice for multi-hazard early warning systems as a national strategy for disaster risk reduction, climate change adaptation, and building resilience. In addition, it aims to guide and advocate the implementation and/or improvement of multi-hazard early warning systems, share lessons learnt regarding early warning and increase the efficiency of investments in such systems for enhanced societal resilience.
