GIS in Anticipatory Action#

Why GIS for Anticipatory Action?#

Anticipatory Action (AA) aims to reduce humanitarian impacts by acting before a hazard turns into a disaster. Geographic Information Systems (GIS) play a central role in this process by enabling:

  • Spatial risk analysis

  • Trigger and threshold monitoring

  • Impact estimation

  • Targeting of early actions

  • Evidence-based decision-making

This section of the IFRC GIS Training Platform focuses on applied GIS workflows for Anticipatory Action, grounded in real-world humanitarian contexts.


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.

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

Exercises: GIS for Anticipatory Action#

In addition to the case studies, this section includes hands-on follow-along exercises that focus on the specific GIS techniques used in the case studies:

  • Spatial risk analysis

  • Exposure and impact estimation

  • Working with hazard and vulnerability data

These exercises can be used independently or embedded into broader AA-focused trainings.


Tools and Methods Used in GIS for AA#

Many GIS analyses in Anticipatory Action analyses rely on specialised tools and platforms. These tools are documented in the Tools & Methods section of this platform.

Commonly used tools include:

  • Risk Assessment QGIS Plugin

  • AILAS

  • GAIA

Each tool is documented separately to highlight:

  • Reusability beyond a single case study

  • Application across different hazards and countries

👉 Refer to the Tools & Methods section for detailed documentation.
