Idea
The key concept of this expo is “Diversity of Life” and to build upon the abundance offered by biodiversity of the wetlands to create a sustainable future according to UN Sustainable Development Goals (SDGs). People, Water, and Plants are the three components that are deeply intertwined with each other, and without the first, the latter two may not ever survive. Udon Thani and its people have a deep connection with the fertile land enriched by the river, which has created biodiversity both in nature and humans

For thousands of years, the abundant land of northeastern Thailand has attracted people of all cultures, creating a diversity of people alongside the biodiversity of the land. Udon Thani, itself, has always served as the centre of abundance and civilisation of this region. The diversity of its nature and people has established the city as a trade centre and border city of Thailand to the GMS since the 20th century until the present day, attracting people of all cultures and languages and leading to investment and growth on various platforms.
Expo 2026 will highlight the significance of water in political, social, cultural, and ecological aspects, in order to both preserve and utilise this precious resource to build a sustainable life and smart society where biodiverse plants and culturally diverse people may live in harmony and abundance, with water serving as a bridge and pathways. Udon Thani would inspire the world on how sustainability and balance can create harmony and abundance to be shared with the world in the modern era, where issues of scarcity become increasingly prominent.
