On 23 June 2026, the Cabinet meeting approved the proposal to register the Ubon Ratchathani Geopark as a UNESCO Global Geopark, showcasing Sam Phan Bok, fossil sites, and local culture on the world stage.
On 23 June 2026, Ms. Lalida Pertvivatana, Deputy Spokesperson for the Prime Minister's Office, revealed that the Cabinet approved the proposal to nominate the Ubon Ratchathani Geopark for recognition as a UNESCO Global Geopark by the United Nations Educational, Scientific and Cultural Organization (UNESCO). This was proposed by the Ministry of Natural Resources and Environment to elevate Thailand’s geological, natural, and cultural heritage sites to international recognition, while creating opportunities in tourism, education, and sustainable community-based economic development.
The Deputy Government Spokesperson added that UNESCO Global Geoparks aim to conserve and promote the values of geological, archaeological, ecological, and cultural heritage alongside sustainable area development, allowing local communities to participate in management and appropriate resource use. Currently, there are 229 UNESCO Global Geoparks across 50 countries. Thailand has two certified sites: Satun and Korat Geoparks, while Khon Kaen Geopark is under UNESCO consideration.
/ The “Ubon Ratchathani Geopark” covers four districts, namely Pho Sai, Si Mueang Mai, Khong Chiam, and Sirindhorn, spanning approximately 1,829 square kilometers. It is internationally notable for its geology, especially landscapes formed by Mekong River erosion, such as “Sam Phan Bok” — a large rock reef, steep cliffs, and inclined rock pillars. It is also a significant fossil site in the Khok Kradoc Formation, where dinosaur fossils, flying reptiles, ancient crocodiles, and numerous Cretaceous vertebrates have been found, making it one of Thailand’s most biologically diverse areas in the past.
Moreover, the area holds important archaeological, lifestyle, cultural, and local wisdom values, such as the Pak Bong fish-catching tradition, riverside community cultures along the Mekong, and ethnic groups in the region, clearly reflecting the interconnection between nature, history, and local ways of life.
The Ubon Ratchathani Geopark was established as a local geopark in 2011 and certified as a Thailand Geopark in 2023. It currently has a clear management system with a coordination center located at the Ubon Ratchathani Provincial Administrative Organization. The National Geopark Committee has approved its nomination to UNESCO, recognizing its readiness in geological knowledge, area management, community participation, and continuous development potential.
/ Thailand must express its intention to UNESCO by 1 July 2026 and formally submit the application documents between 1 October and 30 November 2026, before undergoing UNESCO’s expert evaluation and site inspection process.
Ms. Lalida also said that receiving UNESCO Global Geopark status would increase international awareness of Thailand’s natural and cultural resources, attract tourists and scholars worldwide, generate income and economic opportunities for local communities, and promote conservation of natural resources and geological heritage alongside sustainable development. This will mark an important step in enhancing Thailand’s global standing in balanced and sustainable natural resource conservation and management.
