Minefields remain significant threats to civilian populations in post-conflict regions, particularly in areas affected by insurgency. This study examines the impact of minefields on the socio-economic activities of resettled Internally Displaced Persons (IDPs) in selected Local Government Areas of Borno State, Nigeria. The study adopted a mixed-methods approach involving household surveys, Key Informant Interviews (KIIs, and Focus Group Discussions (FGDs). A total of 384 questionnaires were administered to resettled IDPs, while geospatial analysis was used to map landmine and ERW hotspot areas. Descriptive statistics, spatial analysis, and inferential statistics were used for data analysis. The findings reveal that landmine and ERW incidents are concentrated in areas such as Gwoza, Bama, Jere and Kaga Local Government Areas. The presence of explosive hazards has significantly restricted agricultural activities, movement, and livelihood opportunities among resettled IDPs. Risk perception analysis shows that most respondents perceive landmines and ERW as a major threat to their safety and economic recovery. The study concludes that landmine contamination continues to hinder sustainable resettlement and economic recovery in post-conflict communities. The study recommends intensified mine clearance operations, improved mine risk education, and livelihood support programmes for affected populations.
