Тайландтың Ноң Буа Лампху провинциясы

Province of Thailand

Nong Bua Lamphu (หนองบัวลำภู, , ) is one of Thailand's seventy six provinces (changwat). It lies in upper northeastern Thailand, a region also known as Isan or Isaan (อีสาน, being the Thai word for 'northeast'). Neighbouring provinces are (clockwise from North) Udon Thani, Khon Kaen, and Loei. Nong Bua Lamphu is one of the eight quadruply landlocked Thai provinces, as its neighboring provinces are triply landlocked.

Chalawan, an extinct genus of crocodylin, is known solely from its holotype collected in the early 1980s from a road cut near the town of Nong Bua Lam Phu, in the upper part of the Phu Kradung Formation. This single specimen is the most well preserved vertebrate fossil that has been found from the formation. It contains a single species, Chalawan thailandicus.

Nong Bua Lam Phu is famous as the spot where in the 16th century Naresuan, the king liberator of Siam, came to learn of the outcome of a war between the Lao and Burmese in the area of Vientiane. This place was formerly a Lao stronghold and named "Nakhon Khuean Khan Kab Kaew Bua Ban" (นครเขื่อนขันธ์กาบแก้วบัวบาน). During the existence of the Lao Kingdom of Lan Xang (1354–1707), Nong Bua Lam Phu was traditionally given to the crown prince (Uparat) to rule. It was the birthplace of the principal wife of Chao Siribunyasan (พระเจ้าศิริบุญสาร), the last independent king of Vientiane. In 1827, Chao Anou of Vientiane designated Phagna Narin to be governor at the onset of the Laotian Rebellion of 1826–1828. Under Thai rule, the province originally consisted of five amphoe (districts) in Udon Thani province. In 1993 Udon was decentralized and a separate province of Nong Bua Lam Phu was created. It is one of the newest provinces of Thailand, together with Amnat Charoen province, Sa Kaeo province, and Bueng Kan province. On 6 October 2022, a mass murder occurred at and near a daycare center in Uthai Sawan, a town located in the province. A total of 36 people were killed, and 10 others were injured, before the attacker committed suicide. It was the deadliest mass murder by a single perpetrator in the modern history of Thailand.

Nong Bua Lamphu is the poorest province in Thailand according to the Bangkok Post. Incomes, as of 2018, average 41,000 baht annually. The province is largely agricultural. Sticky rice has long been the area's traditional crop, although there has been a shift to sugarcane due to low rice prices and sugarcane's resistance to flooding. In 2016, more than one third of the available agricultural land in Nong Bua Lamphu was used for sugarcane plantations. According to the provincial Office of Agricultural Economics, sugarcane cultivation is expected to rise. In contrast, the area devoted to rice farming shrunk by 73 percent from 2000 to 2016.

The seal of the province shows King Naresuan in a shrine. This shrine was built to commemorate the visit of King Naresuan to the city of Nong Bua Lam Phu in 1574 when he was gathering troops to fight the Burmese kingdoTaungoo. Behind the shrine is a pond with lotus flowers (Nymphaea lotus), which is the provincial flower. The provincial tree is the Siamese rosewood (Dalbergia cochinchinensis).

As of 26 November 2019 there are: one Nong Bua Lamphu Provincial Administration Organisation (ongkan borihan suan changwat) and 24 municipal (thesaban) areas in the province. Nong Bua Lamphu has town (thesaban mueang) status. Further 23 subdistrict municipalities (thesaban tambon). The non municipal areas are administered by 43 Subdistrict Administrative Organisations – SAO (ongkan borihan suan tambon).
