Phon Ngam, Buntharik

Phon Ngam (โพนงาม) is a capital tambon (subdistrict) of Buntharik district, in Ubon Ratchathani Province, Thailand. In 2021, it had a population of 12,757 people. Neighbouring subdistricts are (clockwise from the south) Huai Kha, Bua Ngam, Nong Sano, and Kho Laen, as well as Champassack and Soukhoumma districts of Laos in the east.

History
The area was first settled in the early 1800s, but "Phon Ngam" village gained recognition in 1912 when the central government demoted Buntharik district to a minor district (king amphoe) and relocated the town center from Non Sung village on the west bank of the Lam Dom Noi River to Phon Ngam village on the east. The district was also renamed "Phon Ngam" in 1917. It was then transferred from Khukhan province to Ubon Ratchathani province in 1928, renamed back to the original "Buntharik" in 1939, and later regained its district status in 1958.

Sukhaphiban Buntharik, a local government covering the town center in the Phon Ngam subdistrict, was created in 1956, two years before regaining district status. It was later expanded to cover a larger area in 1983, and upgraded to a subdistrict municipality in May 1999. Meanwhile, the area outside the subdistrict municipality has been governed by the Subdistrict Administrative Organization of Phon Ngam, which was upgraded from the subdistrict's council in 1997.

The westernmost region, consisting of 11 villages, was divided in 1969 to form a new subdistrict, Nong Sano. Later in 1985, seven villages in the western area were additionally separated to form a new administrative division, the Bua Ngam subdistrict.

Geography
The tambon is located in the eastern region of the Buntharik district; the western area is the low river plains of the Lam Dom Noi River (ลำโดมน้อย), while the eastern is highland of Dângrêk Mountains, the border of Thailand and Laos.
