A river too silted up for boats to sail through. A field choked by sand intrusion. These are two of the photos that Nguyen Khanh Tam Anh brought to a conference held this week on hydropower plant development to illustrate the heavy toll that his family and many others have been suffering due to the mass development of hydropower plants in the country’s central regions over the past 10 years.
The conference, organised by the Centre of Social Research and Development, was designed to provide a platform for discussion among authorities, hydropower plants, experts and residents on sustainable development of hydropower plants.Holding up a photo, the resident of Dai Loc District in the central province of Quang Nam told participants that in the dry season, "rivers are parched because hydropower plants do not discharge water. Dai Loc co-operative used to have 120 boats to transporting freight to Nam Giang District, but has had to stop operation.”
According to Anh, 40 households in Dai Hong Commune that used to rely on the boats for their living, have either become jobless or work as seasonal labourers to get by.
Anh also brought up the September incident at Song Bung 2 Hydropower Plant in Nam Giang District, where a tunnel broke releasing about 28 million cubic metres of water that swept away village homes downstream. “We were so terrified that we had to flee to the forest to escape the water. It was terrible,” Anh said.
Further down to the south, about 1,000 households of coffee and pepper farmers in Krong Ana District in the Central Highlands province of Dak Lak also suffer from water shortage due to the Buôn Kuôp hydropower plant in Serepok River.
“Every year, Serepok River provided us with enough water for cultivation and plentiful resources of fish and shrimp. Since the power plant was built, we lost thousands of hectares and our water source has also dried up,” Le Van Trong, a local resident, said.
Ho Da The, a resident of the Ben Van resettlement residential area in Thua Thien-Hue, relocated with his family more than 10 years ago to make ways for the Ta Trach hydropower plant and irrigation reservoir project. However, so far his family has only received 50 per cent of the compensation money it has coming.
To make matter worse, land in the new resettlement area is exhausted and not suitable for cultivation.“The State has built a school there but the local people do not have enough money to send their children to school so the drop-out rate is very high. The local medical centre is also left without doctors because it is too remote," The said.
According to Huynh Phuoc, Vice Chairman of Da Nang City’s Union of Science and Technology Associations, the mass construction of hydropower plants has led to a series of problems in the central and Central Highlands provinces, including flooding, riverbank erosion, drought, degradation of water quality, and problems relating compensation and resettlement of local people.
“Many reasons are to blame for the unsustainable development of hydropower plants, but the main one is human mismanagement. Management has not involved the communites in monitoring the building and operation of plants, especially those directly affected by the plants,” Phuoc said.In fact, many consequences could have been foreseen but were ignored in environmental impact reports (EIR), said Dang Ngoc Quang, an advisor of the Viet Nam Rivers Network.
“The quality of environmental impact reports done by scientific bodies is too low,” he lamented.He pointed out that most of the reports are financed by project investors, which affects their independence, and there is no legal regulation stipulating who is qualified to conduct the studies.
“I think it is high time the State conducted a comprehensive review of the benefits and costs of hydropower plants that EIRs have failed to show after more than 15 years of exploiting natural resources, especially water,” he said.
Even when solutions to mitigate consequences caused by the plants were mentioned in EIRs, they were not implemented.
“The EIR of Dak Mi 4 hydropower plant suggested building dams for reserve water to tackle shortages downstream. But the plant has operated for nearly 10 years now, and the dams are still on paper,” said Dr Quach Thi Xuan, Director of the Da Nang-based Centre for Sustainable Development Consultation. “There was no regulation on who was responsible for building these dams, either.”
To tackle this kind of problems, Xuan said it is necessary to periodically compile and implement environmental management plans following the EIRs. “Probably, we should renew these plans every five years to supplement what is lacking in the EIRs,” she said.
Despite all these complaints and criticism, Le Đinh Ban, Deputy General Director of A Vuong Hydropower Plant Joint Stock Company, called for a "sympathetic view" of hydropower plants as they themselves have also fallen victims to the weather, particularly climate change and El Nino.
Ban was the only representative of hydropower plants to voice his opinions at the conference.“Why did hydropower plants not release water for downstream regions during the summer? It is because we ourselves were a victim of El Nino in the past three years.
“During 2013-2015, we only operated at 30-40 per cent of our capacity due to drought that caused shortage of water in our reservoirs. This year, it was 60 per cent. We did not have enough water so releasing water downstream was limited. During the dry season, we even had to stop operations for three months to provide water for downstream regions,” said Ban.
As for complaints that irrational water discharge during flood seasons has exacerbated flooding, he said it was necessary to understand clearly the role of the plants and the local authorities.“In the dry season, we are in charge of operating and adjusting water discharge, but during flood seasons, this job is under the responsibility of the provincial centre for flood and storm prevention.
