advantages and disadvantage of building a dam on the Mekong River.
dsadvantages
For Cambodia, Vietnam and Laos
- Lower Dam San Jose To cause serious damage to occur to fish. Deposition of sediments And other natural resources; Local river Cambodian citizens and neighbors.
- Xayaburi dam will affect ecosystems, livelihoods will pose serious health effects, including access to food, water to communities in the Mekong countries.
- Xayaburi Dam It allows a lot of fish spawn. The area where the water is exposed to oxygen in the high-volume gravel for spawning. The dam in this area will make a total of eight of the 10 fish species decreased significantly. Which is the main food source of Cambodians. Vietnam lost Main dishes from the Mekong estuary area
- Will cause serious changes to the nature of the system of river flooding and drought.
- Will cause blocking the flow of sediment.
- Are causing these changes will cause adverse effects. Greatly to the livelihoods of millions of people. Which live at the bottom of the river in Myanmar, Thailand, Laos, Cambodia and Vietnam.

The advantages
- To generate electricity
- To reserve water for use in the dry season.
- To find a solution to the Andaman Sea. By connecting the Mekong River to exploit the Salween River in Burma. If not connected by water. You will find a way to connect by road or rail instead. Recently, China took all the way no matter the road or path R3A Kunming - Bangkok via Laos to Chiang Khong. And China will also support the building of a bridge as well.

- To cooperate with developing countries in the Mekong route free Myanmar, Thailand, Laos, Vietnam and Cambodia under the framework of economic cooperation squares. Economic and hexagon
- The project to build a dam and ditch the project. The benefits of irrigation, transport and energy.
