Overview of Dong Thap province
As a province in the Mekong Delta, Dong Thap is 165 km away from Hochiminh City, bordered by Pray - Veng district (Cambodia) in the North with a length of more than 48km; Vinh Long and Can Tho in the South; An Giang in the West; and Long An and Tien Giang in the East. With an area of 3,374km2, Dong Thap is divided into 12 administrative regions, comprising of 1 provincial city (Cao Lanh), 2 towns (Sa Dec and Hong Ngu) and 9 districts (Cao Lanh, Thap Muoi, Thanh Binh, Tam Nong, Tan Hong, Hong Ngu, Chau Thanh, Lai Vung and Lap Vo).
The topography of the province is quite flat with a sloping tendency from North to South and West to East; separating into 2 large regions: one in the North of Tien River (having an area of 250,731ha, in Dong Thap Muoi area) and one in the South of Tien River (having an area of 73,074ha, lying between Tien River and Hau River). Dong Thap benefits from a large river, channel and spring system, frequently silt-aggraded soil, and permanently fresh and non-saline water source.
Dong Thap is in the tropical climate zone, consistently in the whole province. There are two evident seasons; rainy season from May to Nov, and dried season from Dec to Apr of the following year. Average rainfall ranges from 1,682-2,005mm, mostly in rainy season which accounts for 90-95% of annual rainfall. Such climate is fairly advantageous for agricultural development. The average temperature is 27oC, of which the highest is 34.3oC, and lowest is 21.8oC. The hydrology of the province is under the influence of 3 factors: floodwater from upper Mekong River, in-field rain and tides of the South East Asia Sea. The hydrologic regime is divided into 2 seasons: exhausted season from Dec to Jun of the following year and flood season from Jul to Nov.
