1. Overflowing Refugees: The Darfur conflict resulted in the displacement of around 2 million refugees, many of whom fled into neighboring Chad, adding extra strain on the already scarce resources of the region.
2. Intercommunal Clashes: The conflict's spillover led to increased tensions between the Chadian and Sudanese communities along their common border, often causing intercommunal clashes and violence.
3. Diplomatic Strain: The conflict put a strain on the relationship between Chad and Sudan, disrupting cross-border trade, diplomatic ties, and leading to occasional violent clashes between the two countries.
4. Chadian Involvement: at one point, Chad became involved in the conflict by supporting rebel groups fighting the Sudanese government, further worsening the situation in Darfur.
5. Security Burden: The conflict led to an increase in the regional military presence, including the deployment of international forces, which imposed an extra security burden on Chad's resources.
6. Economic Impact: The deterioration of security and political instability resulted in disruptions to trade, tourism, and foreign investments, affecting Chad's economy.
7. Humanitarian Crisis: The influx of refugees and the strain on resources led to humanitarian crises in eastern Chad, straining the capacity of aid agencies to provide assistance to those impacted by the conflict.
