Nguyen Van Sau from Duc Xuyen Commune said that 5,500 square meters out of 6,000 of his coffee plantation area has been swept away.

A nearby corn field of Dang Van Thanh is also sliding into the river. Thanh said that each time the Buon Tua Srah Hydropower Plant releases excess water, a 10-30cm patch of land from his field just slides into the river.

Landslides are also severe in Nam N’Dir Commune. Local resident Ban Tien Dung has one hectare of farmland along the Krong No River but 0.8 hectare has already slid into the river ever since the Hydropower Plant began operating.

Some irrigation works along the river like Dac Ren and Buon Choa are also in danger of being swept away. These are located barely 20-25 meters from the banks of the river. 

Nguyen Van Quoc, head of the Department of Agriculture and Rural Development in Krong No District, said that the Krong No River runs across 40 kilometers through five communes in the district.

Fifteen kilometers of the river bank in the district is facing landslides, which have already snapped 30-40m of the mainland. The worst affected area is in Duc Xuyen Commune, where landslips have devoured hundreds of meters of mainland.

The Krong No District authorities have dropped iron nets holding rocks and boulders into the river to prevent landslides from eating further inland. However the fast river current is even sweeping the heavy rock nets away.

The Buon Tua Srah Hydropower Plant has also caused flooding of tens of hectares of plants in Nam N’Dir and Duc Xuyen Communes.

Ly Van Tu said that four hectares of his rice fields have been inundated because the hydropower plant discharged water.

Nguyen Van Toan, deputy director of the Department of Agriculture and Rural Development in Dak Nong Province, said that in the last few months, about 40 hectares of plants have been flooded with 10 hectares being completely destroyed.

Farm lands of 92 households in Nam N’Dir Commune and 62 households in Duc Xuyen Commune are flooded, even though this is the dry season.
