How effective are impact-based warnings and what data do we need to implement them?

About
The World Meteorological Organization (WMO) has proposed Impact Forecasts and Warnings (IFW) to improve early warning systems by adding knowledge of impacts, vulnerability, and exposure to hazards. However, the limited research that has been conducted on the effectiveness of IFW so far have shown mixed results in terms of changes in risk perceptions and behavioural responses. While many of the research findings point towards a positive increase in risk perceptions on receipt of impact information, the influence on resulting actions taken are not as clear. Dr Sally Potter will give an overview of the research findings of this topic.
If IFW systems are implemented, we need to know which impacts, vulnerability and exposure data to use to inform them, and where to get them from. Sara Harrison has conducted her PhD research on this topic. Using Grounded Theory (GT), interviews and workshops were conducted with 59 users and creators of hazard, impact, vulnerability, and exposure (HIVE) data within and outside of Aotearoa New Zealand. This research advances the discussion around implementing IFWs as per the WMO’s guidelines, and around building up disaster risk data in accordance with the Sendai Framework Priorities. An important outcome of this research is the provision of a pathway for stakeholders to identify data sources and partnerships required for implementing a hydrometeorological IFW system.
