PRISM mitigates the impact of climate-driven hazards by presenting decision-makers with the most up-to-date risk and impact analytics available. This information feeds into several program areas, including climate risk monitoring and climate-informed decision-making in the agriculture sector, disaster preparedness, disaster response, disaster recovery, and adaptive social protection — also referred to as shock-responsive social protection (SRSP).
In the case of slow-onset disasters like droughts, PRISM provides decision-makers with an overview of current conditions and how they differ from long-term averages. It combines this information with data on vulnerable groups. This can then be used to highlight areas at risk and to inform potential early actions to mitigate the impact of a disaster. For example, areas with drier than usual conditions in the critical planting season can be identified, and locations prioritized based on the presence of farmers with low resilience to climate shocks to plan timely interventions.

When an acute disaster strikes, such as a tropical storm (cyclones, typhoons, hurricanes), PRISM can rapidly produce statistics on the number of people potentially exposed to damaging wind speeds. This quick estimate helps governments and humanitarian partners immediately assess the scale of the disaster without deploying people on the ground, which can be used for initial response planning and humanitarian assistance if required.

As a tool for governments, PRISM is increasingly being linked to social protection systems which provide aid to those most in need throughout the year. However, when a disaster strikes, social protection systems can be scaled up to expand coverage to new households and/or increase the level of assistance to households already receiving. Thresholds are established and monitored to establish when and to what extent natural hazards should trigger these increases. PRISM can facilitate these triggers through its alert system, where users can create a threshold to monitor for a hazard in a given location. When the threshold is exceeded, a message is sent to the user to take further action.
