During 21-24 August 2017, the Royal Thai Embassy in Copenhagen in collaboration with Hydro and Aqua Informatics Institute (HAII), Ministry of Science and Technology of the Kingdom of Thailand, organized a seminar entitled “Thailand-Denmark Collaboration on Water Resource Management.” Speakers with expertise in water resource management were invited from DHI Group (DHI – Institute for water and environment) from Denmark. The seminar consisted of lectures, group discussions and study visits, which provided opportunities for Thai experts to learn new techniques and exchange experiences with Danish experts in water resource management, particularly in seeking solutions to prevent flooding and manage waste water. Moreover, the said seminar could lead to future cooperation in other areas of water management between Thailand and Denmark.
