This year the Mekong Delta did not have floods but whenever it rained heavily or there were tides, floods occurred in many places, even in towns located on high terrain.
According to the latest statistics by Prof. Dao Xuan Hoc, former Deputy Minister of Agriculture and Rural Development, the Mekong Delta has built 19,900 km of dikes to protect more than 6,000 pieces of rice fields with three crops/year and 17,700 km of dikes to protect over 4,000 pieces of rice fields with two crops/year. The dike system in the Mekong Delta is nearly 30 times longer than the dike of the Red River in the North.
The building of embankments for protection of rice fields mainly took place in the upstream provinces as An Giang and Dong Thap, where flooding is often very deep, up to 5-6 meters. As the dikes are built, the huge amount of water in the areas protected by embankments runs to downstream areas, causing flooding there.
