Technology and Innovation in a Crisis

The power of Geographic Information in a Disaster

Geographic information helps humanitarian workers make data-driven decisions, improving efficiency and effectiveness in disaster management across all phases of Disaster Risk Management.

Prevent

GIS enables organisations to assess and map disaster risks by analysing factors such as terrain, climate, population density, and vulnerability. ​Geospatial data allows for the creation of early warning systems. By monitoring indicators like crop health, rainfall patterns, and population density, humanitarian agencies can anticipate future crises and take preventive measures.

Prepare

During the Prepare phase, geographic analysis is key to mapping vulnerable areas, ensuring resources are effectively distributed, and developing comprehensive action plans. It helps identify safe evacuation routes, locate critical infrastructure, and understand how different areas are connected, which enables coordinated preparedness strategies. By detecting emerging risks and forecasting future vulnerabilities, humanitarian teams can better prepare for potential disasters, ensuring communities are ready to respond when needed.

Respond

In the Respond phase, geographic information plays a critical role in rapidly assessing disaster impacts and directing aid where it is most needed. It helps identify affected areas, evaluate damage, and find the best routes for emergency teams. By detecting patterns in the disaster’s impact and predicting evolving challenges, geospatial data ensures an efficient, targeted response that adapts to the needs of the situation. This enables humanitarian workers to act quickly and allocate resources to the most vulnerable communities.

Recover

The Recover phase relies on geographic analysis to prioritise rebuilding efforts and ensure long-term recovery. By measuring the extent of damage, identifying key locations for reconstruction, and analysing connections between affected areas, geographic information supports strategic rehabilitation. It also tracks recovery progress, allowing teams to adjust their strategies and focus on areas that need the most help. This forward-looking approach ensures that recovery efforts are sustainable and communities emerge stronger and more resilient.
