Since August 2026, escalating conflict and shifting front lines have laid new mines along roads and aid routes. Nearly two-thirds is in Ta'iz, including anti-personnel and anti-vehicle mines and disguised improvised explosive devices. Between 30 October and 2 November, shelling, sniper fire, and landmines killed or injured 44 civilians, including 18 children, in the governorate. Displacement is increasing exposure, with over half of the 300,000 people displaced since August sheltering there. New mines along West Coast transport corridors threaten travel through unfamiliar areas and limit access to services and aid. Over 134,000 Horn of Africa migrants arrived in September, adding to those at risk. Yemen was already among the most contaminated countries, with Al Hodeidah and Ta’iz among the worst affected. Between July 2023 and June 2026, Danish Refugee Council surveys identified over 2.1 million m² of minefields, adding to the 57 million m² recorded earlier.

Since 24 October 2026, heavy rains and flooding have been affecting Grand’Anse, Nippes, and Sud departments in Grand Sud region, damaging 2,600 houses, one hospital, and at least one public school. In Nippes, flooding has affected 1,920 families (approximately 8,000 people). Agricultural land has been flooded, including La Hatte Plain in Pestel municipality. This comes after farmers across Grand Sud faced a dry period between April–September, which reduced food production and availability. Nippes is among the departments with areas facing Emergency (IPC Phase 4) food insecurity between September 2026 and February 2027, reflecting severe food consumption gaps and reduced capacity to meet basic food needs. Grand Sud is also home to around 39% of Haiti's 1.5 million IDPs by mid-August; IDPs, who are hosted by families already in need of assistance, may be particularly exposed. Affected families urgently need shelter, WASH and health services, and food. (OCHA 28/10/2026, IOM 23/09/2026, IPC 28/10/2026)

Heavy rains between 28–30 October 2026 caused flash floods across Aleppo, Al Hasakeh, Ar Raqqa, Deir ez Zor, and Idleb, killing seven people and damaging critical infrastructure, especially across displacement camps. Flooding forced 375 families to evacuate three camps in rural Ar Raqqa and damaged tents in Al Hasakeh. Al Salmani Bridge collapsed, cutting the Ar Raqqa–Aleppo road. At least three bridges in Deir ez Zor became unusable, restricting access. In Kasrat Surour village, flooding stranded over 100 families, requiring army helicopter assistance. It also damaged telecommunications, disrupted water supplies, and affected two hospitals, schools, and bakeries, which may further isolate displaced communities and limit service access. People likely need emergency shelter, safe drinking water, food, sanitation and hygiene assistance, and medical support. An estimated 2.4 million people are expected to need winter assistance from 2026–2027 amid forecasts of above-average rainfall and flood exposure across 1,074 displacement sites.
