SUD, IOM, Displacement Tracking Matrix (DTM)

Since the outbreak of conflict in April 2023, Sudan has become the site of the world’s largest displacement crisis, with 12 million people displaced internally at its peak in January 2025 (8.8 m as of May 2026). Humanitarian needs remain immense, affecting an estimated 33.7 million people, while civilians continue to face severe protection risks and violations. 

The crisis has also spilled across borders, with neighbouring countries such as Chad, South Sudan, Libya, and Egypt hosting 4.5 million refugees and returnees, many of whom face significant risks and lack basic services. At the same time, 4.2 m people have returned to their areas of origin including 618’000 from abroad, despite fragile conditions, damaged infrastructure, and limited access to services.

These complex and overlapping movements - ongoing displacement, cross-border flows, and returns - are placing significant strain on already vulnerable systems and underscore the need for timely, coordinated humanitarian responses.

Objective (impact level): Improve humanitarian response in Sudan through timely, reliable, and protection-sensitive data on displacement, returns, and needs.

Outcome: Strengthened systems for monitoring displacement and returns, enabling trend analysis, early warning, and better preparedness and recovery planning.

Principaux résultats attendus:  

Regular reporting: Mobility Tracking (4), Flow Monitoring (2), Early Warning Alerts (37).

Capacity building: 1 refresher training for field staff and enumerators.

This is SDC’s first contribution to DTM Sudan.

DTM Sudan has established and sustained the only ationwide displacement monitoring system covering all 18 states, monitoring over 12,000 locations and producing nearly 1,000 information products since April 2023. The data has become central to humanitarian coordination, early warning, and response planning, providing reliable, timely, and protection-sensitive evidence on displacement, returns, and shocks in a highly fluid conflict context.
