Nong Han Lake, a freshwater lentic ecosystem, is located near Kasetsart University Chalermphrakiat Sakon Nakhon Province Campus (KU-CSC), Sakon Nakhon, Thailand. The photograph was captured by Assist. Prof. Sittichai Hatachote (KU-CSC) in June 2019 using an unmanned aerial vehicle (UAV) for aquatic environmental observation, education, and exploration.
Nong Han Lake (NHL) is the largest natural freshwater lake in northeastern Thailand, covering an area of approximately 123 km². The lake is connected to the Mekong River through the Nam Kham River and provides important ecosystem services and livelihoods for millions of local residents. As one of Thailand's significant wetland ecosystems, Nong Han Lake has been associated with several Royal Development Projects initiated by His Majesty King Bhumibol Adulyadej the Great (Rama IX), particularly those aimed at improving the well-being and livelihoods of local farming communities.
The lake is situated within the Lower Mekong Basin (LMB), one of the world's most biologically diverse regions and the second-richest river basin in terms of biodiversity after the Amazon Basin. Its ecological importance makes it a valuable site for environmental research, conservation, and sustainable resource management.
Our research focuses on various aspects of the lake ecosystem, including fish biodiversity, aquatic plant distribution, water quality assessment, fishing gear utilization by local fishers, invasive alien species, fisheries resource management, and the application of geospatial technologies for wetland monitoring and conservation.
