This special issue looks at perspectives from organizations on challenges and step changes for addressing natural hazards. In this special issue, we ask representatives of national and international organizations to identify, from the point of view of the organization, (i) what the most pressing scientific challenge(s) with respect to natural hazards is and (ii) what broad step change(s) should or could be achieved by the scientific natural hazard community to address natural hazards.

The format will be one- to two-page invited perspectives (not including any references cited).

This special issue will be published as part of the 20th anniversary of the journal Natural Hazards and Earth System Sciences (NHESS). We invite any representatives of national or international organizations involved with natural hazards to write to the guest editors (NHESS executive editors) for inclusion in this special issue.
