Laos Peopleai??i??s Democratic Republic (Laos PDR) is located in the heart of the Indochinese peninsular, in Southeast Asia, at a latitude of 14 to 23 degrees north and longitude 100 to 108 degrees east.
The plains region comprises large and small plains along the Mekong River. The largest of these is the Vientiane Plain, on the lower reaches of the Nam Ngum River. Also significant are the Savannakhet plain, on the lower reaches of the Se Bang Fai and Se Bang Hieng rivers, and the Champassak plain, which is on the Mekong River, stretching between the Thai and Cambodian borders. Blessed with fertile soil, these plains represent one quarter of the total area and are the “granaries” of the country.
About rivers in Laos
The Laos is criss-crossed by many rivers and streams. The Mekong River flows through 1,835 km of the country from north to south. Rivers and streams provide great potential for hydropower development. Over half of the power potential in the lower Mekong Basin is contained within Laos.
The Nam Ou river flows from Phonsaly to Luang Prabang for 448 km; the Nam Ngum runs 354 km from Xieng Khouang to Vientiane province; the Se Bang Hieng of Savannakhet province is 338 km long; the Nam Tha runs from Luang Namtha to Bokeo for 325 km; the Nam Sekong runs 320 km from Saravane and Sekong to Attopeu province; the Se Bang Fai runs between Khammouane and Savannakhet for 239 km; Oudomsay province’s Nam Beng covers 215 km; the Nam Sedong flows for 192 km between Saravane and Champassak; the Nam Selanong in Savannakhet runs for 115 km; the Nam Kading of Borikhamsay province is 103 km long; the Nam Khanh runs for 90 km between Huaphanh and Luang Prabang.
Being a tropical country, the weather in Laos is influenced by monsoons. The weather in the mountains in the north and in the high range of the Annamite Chain bordering Vietnam in the east is semi-tropical. The difference in day and night temperatures is about 10 deg C.
The forest regions are also rich in non-timber products such as shellac, benzoin, cardamon, pine resin, rattan and medicinal plants, and there is a wide range of fauna, including elephants, tigers, bears, deer and a newly-discovered species of deer called Saola.
Such wealth represents a great potential for the development of the country, ensuring a brighter future and better living standards for its people.
