Flooding is an urgent issue in the Mekong Delta, the largest agricultural area of Vietnam. While flooding completely destroyed the Mekong Delta is one sided. This natural and social phenomenon has been accepted by residents during the settlement and evolution of this area. From passively living with flood, people increasingly understand more about the flood, and are able to gradually minimize the harmful impacts as well as optimize the benefits from floods. In this project I would like to analysis the reason why and how Flooding become a big issue in this area.
