Food insecurity, drought, flooding, disease outbreaks, the impact of decades of instability and war, and limited resources have contributed to an ongoing complex emergency in Chad since 2004 (USAID 02/2011). Poor agricultural performance in 2011 has triggered the alarm of a food insecurity crisis (CPI Phase 3) for the period July-September 2012 (FEWS 02/2012). Field reports from several NGOs confirm the deterioration of the situation with increasing numbers of patients attended in nutrition centres. This report overviews the many reasons and consequences for IDPs and refugees in Chad.
