Two of Dong Nai hydropower dams cancelled due to environmental concerns, Vietnam

Thanks to effective lobbying by civil society groups, independent experts and governmental actors, the dams were cancelled and environmental justice could be served to a unique ecological, social and cultural region.


The Dong Nai dams no. 6 and 6a, located on the Dong Nai River, were planned as part of a series of dams proposed to cover Vietnam’s growing demand for energy. However, the Dong Nai River has always been a crucial source of water and life for the surrounding villages and ecosystems, such as the Cat Tien National Park, which received UNESCO’s recognition as a Biopshere Reserve Zone in 2011.

Project Details and Actors
Project DetailsThe dam would have large negative impacts on Cat Tien National Park, which was recognized by UNESCO as a world biosphere reserve on June 28, 2011 [2]. The park covers almost 1,000,000 ha and spans across the provinces of Dong Nai, Lam Dong, Binh Duong, Binh Phuoc and Tay Ninh [7]. Around 450,000 people live in the biosphere Reserve [7].

The Dong Nai dam 6 was initially approved by the Prime Minister under Document No. 1483/CP-CN dated 19 November 2002 and required flooding of 1,954 hectares. The project was later on modified and split into two smaller dams, which reduced the reservoir size to 372.23ha [9].

Dong Nai dam 6 had a planned capacity of 135 MW. Dong Nai 6a had a planned capacity of 106MW [6]. Other sources state that the whole project would have produced 929 million kWh and 14,400 USD of tax revenues per year [2].

The investor who was going to implement the dam was the Duc Long Gia Lai Group Joint Stock Company [3]. It was reported that the company failed to conduct an assessment in compliance with the Laws of Biodiversity and Heritage [5]. The company was said to have invested in the project (feasibility studies, etc.) since 2002 [8]. No information on the total required investment size could be found.

Many ethnic minorities live in the area [8]. Most affected by the dam would be the Chau Ma and M’Nong ethnic minority people [10].
