What happened, where and when?
Between 21 and 30 July 2025, heavy rainfall associated with the remnants of Tropical Depression Wipha caused widespread flooding, flash floods, and landslides across northern and central provinces of Lao PDR, including Vientiane, Bolikhamxay, Luang Prabang, Xayabouly, Xiengkhouang, Houaphan, Xaysomboun, Khammouane, and Bokeo. The event resulted in significant impacts on at-risk communities, infrastructure, and livelihoods, as reflected in successive UN situation reports and initial government assessments.
According to the UN Lao PDR Monsoon Situation Report (Sitrep) No. 5 published on 31 July 2025, in Khammouane Province, flooding in Hinboun District between 27 and 28 July submerged homes; some up to roof level and affected 13 villages and over 335 families.
Agricultural losses included damaged rice fields, crops, livestock, and fishponds, while temporary road inaccessibility further disrupted movement and response efforts. Total damages in the district were estimated at over LAK 1.2 billion (approximately CHF 44,581). At the time of reporting, no updated information was available regarding the number of affected people who had received assistance.
Rising water levels along the Mekong River and its tributaries further heightened flood risks, reaching warning thresholds in several locations, including Vientiane Capital and southern provinces. Authorities and the Department of Meteorology and Hydrology issued alerts for communities in low-lying and riverside areas, urging preparedness for potential continued flooding and landslides.
By the end of the DREF operation, reconstruction efforts remained ongoing in some areas. Basic services, including water supply and health care, were largely restored, although access to clean water continued to be limited in some remote communities.
Government-led interventions, supported by humanitarian partners including the Lao Red Cross (LRC), addressed the most urgent needs during the initial response phase. Early and mid-term recovery interventions were also implemented in affected communities to address challenges in restoring livelihoods and rehabilitating damaged infrastructure. ...
