The Lower Songkram River Basin (LSRB) encompasses a broad range of wetland habitats associated with the functional floodplain ecosystem that link to the Mekong Basin. Due to various habitat types, the Basin contains valuable natural resources. Communities located along the Songkram floodplain exhibit a high degree of dependency on wetland resources for their livelihoods such as capture fisheries, fish processing, harvesting wetland products, agriculture and livestock grazing. Thailand’s economic development during the past decade results in changes of local livelihood and greater complexity. Fish captured as a means to barter for essential goods has changed to fishery for cash income. Conflicts are occurring between small and large scale fishers. Wetland ecosystems in the LSRB are gradually converted to farmlands such as eucalyptus plantation and tomato field. The wetland ecosystems are also deteriorating from human activities, especially big dams on upper Mekong Basin and weirs as well as from the impact of climate change. The studies conducted during 2004-2006 on wetland ecology, biodiversity and resource utilization in the LSRB indicate that impacts to wetland ecosystems and community structures are well-recognized but practical and economical wetland ecosystem management at local and regional scales remains limited. Due to early water level decrease in dry season, construction of check dams in sub-tributaries is recommended to balance water levels and extend flooding periods.
