Since 2009, Boko Haram's insurgency has inflicted catastrophic human, economic, and social costs, primarily in Northeast Nigeria but spilling across the Lake Chad Basin.
Human Rights Watch estimates over 25,000 killed (2009–2018); total deaths including indirect causes (starvation, disease) are far higher.
2+ million internally displaced persons (IDPs); hundreds of thousands fled to Niger, Cameroon, Chad.
Suicide bombings (often using child "carriers"), mass abductions (e.g., Chibok, Dapchi schoolgirls), sexual slavery, extrajudicial killings, village razing.
Hundreds of schools destroyed or closed; generations of children denied education in the epicenter.
Agriculture (the region's backbone) collapsed; markets, trade routes, and infrastructure destroyed; poverty and food insecurity soared.
Eroded trust in government; fueled heavy-handed military responses; triggered multinational military coalition (MNJTF); strained Nigeria's federal unity.
Even as territorial control shifts, the humanitarian crisis, trauma, and radicalization drivers persist. Peace requires security, justice, development, and deradicalization—not just military victory.
