Water represents a basic component of the economy in the region, in addition to domestic consumption, water is also used for agriculture, industry and services. Rivers and riparian areas also contribute to the landscape for the area and the development of other tourism services. In addition, the river is also a connection and creates habitat for many terrestrial and aquatic creatures and creates other aesthetic and recreational values. In the Mekong Delta, the Mekong River is considered the most important source of water and ecosystem services because it provides about 90% of the water flow for the Mekong Delta, especially in the dry season, entirely dependent on the upper Mekong region. However, river basins have been over-exploited to serve socio-economic development goals, thereby causing pressure on the ecosystem. Meanwhile, many rural communities and ethnic minorities are still heavily dependent on river water. Currently, the value of ecosystem services provided to the community has been gradually forgotten, leading to activities that cause many negative impacts to the river frequently. Therefore, the project evaluated the ecosystem services that the river actually provides to people in order to change the current thinking about river management.
The result revealed that the ecosystem services generated by th River are diverse and play a very important role in the development of the whole Mekong Delta. It is the source of water and food for many of the region’s activities. The river has directly and indirectly offered various regulating and supporting services, such as climate regulation, nutrients, etc. Moreover, this is considered the place where many festivals and beliefs activities take place on the river, featured with many eco-tourism activities and types of experiential tourism. The role of the provisioning services were the most interested people in the survey process. However, these services have been increasingly degraded by a variety of factors such as hydrological changes, quality, reduced water resources, and river-related development policies. In which, the change in water quality and quantity is one of the main causes leading to the change of ecosystem services on the river.
