Vietnam Rivers Network call for protection of untouched rivers
Dr Dao Trong Tu, Vietnam River Network (VRN)’s head coordinator, said many countries are searching for a ‘virgin’ river – untouched by hydropower plant dams and reservoirs and other development projects, to keep it for the next generation.
Tu, who was a member of the country’s Mekong River Committee, told participants in Ha Noi, Thanh Hoa, Thua Thien-Hue, HCM City and Can Tho at an online seminar held on Wednesday evening that rivers were being transformed.
“Searching for untouched rivers is significant because many rivers around the country are impacted by construction. The call to protect rivers shows the meaning of an untouched river to riverbank communities and hydrology, as well as nature and culture,” Tu said.
At the seminar, participants agreed that the most common harm to rivers across the country were power dams and reservoirs as well as the encroachment of water surface to have more space for urban construction.
Associate Prof Dr Le Anh Tuan from Can Tho University said dams cut a river into sections and each section becomes a lake. “A chain of lakes means a river no longer exists and this could affect both environment and society,” he said.
Communities along the Ma River in Thanh Hoa Province witnessed these changes after five power plants were built on several sections.
Truong Thi Thuy, a resident from the province’s Ba Thuoc District, said after the Ba Thuoc power plant was built, the community experienced intermittent flooding.
“Water rose more quickly than before. The flood level was also higher and each flood left wet mud, harming agriculture,” she said.
Pham Thi Son, a resident in the province’s Cam Thuong District, said power plants along the Ma River released water, affecting the lives of residents as many villagers had to quit their jobs to look after their properties.
Pham Thi Dieu My, director of the Hue-based Centre for Social Research and Development, added that communities with water worship rituals in the Central Highlands had to stop events as the rivers were blocked off for power dams.
According to Dr Tu the call to protect rivers does not mean an opposition to power plants, but to inspire smart policies as well as the approval of power plant projects by policy makers and governmental agencies.
“Obviously hydropower plants are necessary for development. However, related governmental agencies should rethink the number of plants on one river and the quantity of dams and reservoirs in each locality,” he said.
“Authorities in the field should also have a look at the development and operation of hydropower in the country.”
Dr Tuan of Can Tho University suggested strict compliance with regulations in power plant development as well as the water policy among power reservoirs.
“The construction and the operation of the reservoirs flooded a wide area of trees, but a very small area was replanted as per the commitments stated in the investment licence,” he said, adding that risk reduction measures included in the investment report were rarely applied in practice.
Tuan demanded closer supervision by local authorities as well as alarms prior to any release of water during the flooding season.
Tu said saving rivers to save humans from climate change is a global trend. He said VRN expected to see Vietnam move to protect rivers and keep some of the 340 rivers across the country untouched for future generations.
