GIS in Anticipatory Action #

What is Anticipatory Action? #

Anticipatory action in humanitarian work means taking early steps to reduce the impact of disasters before they fully occur, based on reliable forecasts and risk analysis. The International Federation of Red Cross and Red Crescent Societies applies this approach through Forecast-based Action, releasing pre-arranged funding when specific risk thresholds are reached. This enables local Red Cross and Red Crescent teams to act in advance—such as distributing cash, protecting assets, or preparing communities—helping to save lives, reduce losses, and strengthen resilience in a more timely and cost-effective way.

Why GIS for Anticipatory Action? #

Anticipatory Action (AA) seeks to reduce humanitarian impacts by taking action before a hazard escalates into a disaster. Geographic Information Systems (GIS) support this approach by enabling spatial risk analysis, monitoring triggers and thresholds, estimating potential impacts, and identifying where early actions should be targeted. By integrating these capabilities, GIS helps humanitarian actors make timely, evidence-based decisions. This section of the IFRC GIS Training Platform highlights practical GIS workflows for Anticipatory Action, grounded in real-world humanitarian operations.

GIS plays a central role in anticipatory action by helping humanitarian actors understand where and who will be affected before a hazard occurs. By combining forecast data with geospatial information—such as population distribution, infrastructure, and accessibility—GIS enables the identification and mapping of exposed and vulnerable communities. These analyses support data-driven decisions, such as where to prioritize early actions, how to reach people in time, and which areas face the greatest risk. Ultimately, GIS transforms complex data into actionable insights, allowing organizations like the Red Cross to target support more effectively, act earlier, and better protect lives and livelihoods.


What You’ll Find in This Section #

The GIS in Anticipatory Action content brings together case studies, applied analyses, and exercises that demonstrate how GIS supports AA across different hazards and countries. These examples illustrate how geospatial analysis can support the development of anticipatory action protocols, including risk analysis, trigger monitoring, impact estimation, and the targeting of early actions.

The case studies present applied GIS workflows based on real operational contexts and highlight the tools and datasets used in the analyses — many of these tools are documented in more detail in the Tools & Methods section.

You will find:

  • Country- and hazard-specific case studies

  • End-to-end GIS workflows

  • Examples of trigger and impact analyses

  • Exercises focused on AA-relevant methods

This content is designed for:

  • GIS trainers

  • AA practitioners

  • Technical staff supporting anticipatory decision-making
