Vietnam - Central Vietnam faces drought, partly caused by hydro-power plants

VietNamNet Bridge – Tens of thousands of hectares of rice and crops in provinces in central Vietnam are in need of water now.

Mr. Huynh Van Thang, deputy director of the Da nang Department of Agriculture and Rural Development, said that around 6,000 hectares of crops are threatened by drought.

In Thua Thien – Hue province, half of the rice area lacks water.

In Phu Yen province, Dong Cam, the largest irrigation work in the province, which supplies water for 15,000 hectares of rice, is seriously dry.

At present, thousands of households in the downstream regions of Thu Bon, Vu Gia rivers in Quang Nam and Ba River in Phu Yen are thirsty for water.

Besides prolonged dry and sunny weather, drought is caused by hydro-power plants, which store water for power generation.

Localities which do not have hydro-power plants on the upstream arrears, for example southern Quang Nam, southern Quang Ngai and northern Binh Dinh, do not lack water. This is the clear evidence for impacts of hydro-power plants.

Since Dak Min 4 hydro-power plant changed the flow of Vu Gia River, Da nang has lacked water during the dry season. Da nang used to lodge complaints to the government, asking Dak Min 4 to return water to Vu Gia River, at least 48cu.m per second but this plant only released water back at the speed of 7cu.m/second.

This situation happens again this year. “We cannot discharge water at 25cu.m/second speed because we will lack water for power generation,” said an official of Dak Min 4.

If Dak Min 4 causes drought and salt-water encroachment in northern Quang Nam and Danang City, in Phu Yen, hydro-power plants on Ba River are the culprits of drought.

At this moment, most of plants try to store water, neglecting Phu Yen authorities’ request and the Ministry of Industry and Trade’s instruction. They argue that they lack water and they have to operate under the “competitive power market” policy, which starts from July 2012. Competition is good but why they compete with farmers?

This has become a yearly routine: storing water in dry and sunny weather and discharging in rainy and flooding season.

A competitive power market aims to ensure competition in power production and pricing, improve efficiency and attract more funding for power generation. As the power generation market becomes more developed, customers will have more opportunities to select power providers. The market operates under the model of a cost-based pool in which power producers have the right to offer power prices based on the market.

Deputy PM gets tough on dams

Hydropower projects that have significant negative impacts on the environment should be rejected and existing ones that violate regulations should have their licences revoked, says Deputy Prime Minister Hoang Trung Hai.

These include projects that need large areas of forest and/or agricultural land; affect large numbers of residents and result in big resettlement plans; and affect water resources on the lower sections of rivers on which the dams are built, he said in a statement on the Government website.

Hai asked the Ministry of Trade and Industry to review development plans for hydropower projects on each river as well as small-scale ones planned by every locality nationwide.

The Ministry of Trade and Industry should cooperate with provincial authorities to make developers (of hydropower plants) to re-assess their designs, propose operational and management measures to ensure safety of life and property in downstream areas during flooding seasons, he said.

Hydropower projects currently under construction must be inspected and violations in construction and quality management and supervision must be strictly punished, Hai said.

The Ministry of Trade and Industry must cooperate with the Ministry of Agriculture and Rural Development to monitor compensation paid to residents affected by these projects so as to ensure that they have better living standards in new residential areas.

Provincial authorities are responsible for allocating land for reforestation to investors of hydropower projects to replace forests destroyed to build dams. They are also required to take measures to ensure that investors reforest an area equal to the forest land allocated for their hydro-power projects, Hai said.

If the province does not have enough land for afforestation, the authorities must ask the investors to pay compensation money to the Forest Protection and Development fund as required by law.

The People's Committees of provinces and cities have to report to the Ministry of Agriculture and Rural Development the area of forest land allocated to hydro-power projects and also the area of land reforested by the investors. The ministry will then send a report to the Prime Minister on this issue.

Provincial and city authorities should also check and assess the capacities of contractors for small-scale hydropower projects.

Licences granted to investors who do not possess the capability to carry out hydropower projects and those who violate regulations on construction, investment and environment protection must be revoked, Hai said.
