The death toll from flooding in Thailand since mid-July has risen to 158, while 61 people have died in neighbouring Cambodia in the past two weeks, authorities in the two countries said on Monday, according to Reuters. More than 2 million acres of farmland in Thailand are now under water, an area 11 times the size of Singapore. \"Twenty-three provinces in the lower north and central Thailand are under water and nearly 2 million people have been affected by severe floods and heavy rain,\" Thailand\'s Department of Disaster Prevention and Mitigation said. Flooding has also affected the capital, Bangkok, which sits only two metres above sea level. The Chao Phraya river has overflowed into roads in some areas, although the authorities have reinforced its banks to prevent serious flooding. The Meteorological Department warned 39 provinces, mostly in central and northeast Thailand, to be ready for possible flooding and heavy rain in the coming week. In Cambodia, Keo Vy, deputy information director of the National Disaster Management Committee (NDMC), said the death toll in provinces along the Mekong River and Tonle Lake was likely to rise once provincial authorities submitted new reports. \"The worry now is about a lack of food, and the health of people and animals,\" Keo Vy said, adding that 163,000 hectares (407,000 acres) of rice paddies and 63,000 homes were under water. NDMC Vice-President Nhim Vanda said flooding in August had already damaged rice paddies around the country. \"The damage is now double,\" Nhim Vanda said. \"We are worried that the water will go down slowly, which will destroy rice that is already planted.\"
