Protracted Lebanon Tensions Generate Significant New IDP Population and Strain on National Systems
Theater: Southern Lebanon
Time horizon: 30d

Moderate confidence (70%)
Risk direction: escalatory · Impact: CRITICAL
Executive summary
Over the next month, continued hostilities along the Israel–Lebanon front and periodic IDF strikes in the south and Beqaa are likely to create and entrench a sizable new internally displaced population, potentially numbering in the low hundreds of thousands. Lebanon’s fragile economy and collapsing public services will be unable to adequately absorb this influx, leading to overcrowded shelters, rising health risks, and increased poverty. International assistance will expand but remain insufficient given donor fatigue and competing crises.
