The issue become more urgent under the impacts of the fourth industrial revolution and international integration as well as the global climate change
Vietnam and the Mekong Delta in particular suffered not only from domestic thermal power projects, but also from projects in China, leading academic.
China’s plan to blast waterfalls and rapids to clear the Mekong River to allow large cargo ships to pass through has raised concerns among the public as it will damage the habitat for marine life and harm people’s lives.
The Mekong Delta is sinking 2.5cm every year because of ground water extraction and unreasonable planning and constructions on the surface.
The Mekong Delta makes up 55.5 percent of the country’s annual rice output. Shortage of floods has resulted in a hefty 50 percent decrease in sediment deposited in the Mekong Delta each year, causing Vietnam’s largest delta to face serious subsidence and likely disappearance in the future.
The current severe drought and rise in sea level has caused saline intrusion in the Sai Gon and Dong Nai rivers. The two rivers supply raw water to more than 10 million residents and to businesses.
The high saline rate along with household and industrial pollutants in the river water has threatened the city’s water supply.
Water treatment plants in HCM City have had to shut down numerous times because raw water taken from the Sai Gon and Dong Nai was below standard.
The salinity rate in the rivers is at the highest level of the last five years, affecting operations of some of the pumping stations that supply water to the city.
Water pollution has become more serious in the Dong Nai River, which supplies 4,000 cu.m water per person in HCM City each year.
