Amphoe Buntharik is a county in the southeast of the province of Ubon Ratchathani. The area is located in the northeast region of Thailand, the so-called Isaan (also Isan). Buntharik was first a ‘branch’ in 1923, whose center was located in Ban Phon Ngam on the eastern bank of Lam Dom Noi. Later the district was called Phon Ngam. In 1939, the name was changed back to Buntharik. On July 22, 1958, Buntharik was promoted to Amphoe.
The Isaan is located on the Khorat high plateau and is bounded to the north and east by the Mekong, to the south of Cambodia. In the west, the Phetchabun mountains, the hills of the Dong Phaya Yen and the Sankamphaeng chain separate the Isaan from the North and Central Himalayas.
In Isaan, agriculture is the predominant economic sector, but because of unfavorable conditions, the yield remains behind that of other parts of the country. The Isaan is the poorest region in Thailand but has in the last years firmly caught up.
