Cambodia is one of the world’s most vulnerable countries to natural disasters and has suffered repeatedly from floods, storms and strong winds which have caused the loss of lives and destruction of livelihoods. In 2018, due to the heavy rainfall from Tropical Storm SON-TINH, the Sepa-Nam Noi dam in Lao PDR collapsed affecting 62,317 households. The massive floods caused 16 deaths and forced 5,398 households to evacuate in the five downstream provinces in Cambodia. The rural poor communities near the Mekong river had suffered the destruction of their houses. Many families were forced to evacuate their homes to the temporary shelters with no sufficient food and access to clean water and sanitation.
