Cambodia: Groups raise alarm over severe food, livelihood, environmental, cultural impacts of Lower Sesan 2 Dam project; companies do not respond


Lower Sesan 2 Dam is located near the confluence of the Sesan and Srepok Rivers in Stung Treng Province, Cambodia – two of the Mekong River’s most significant tributaries. Expert studies have shown that the dam would cause a substantial drop in fish stocks, threaten over 50 fish species and alter the livelihoods and cultures of tens of thousands of people, mostly belonging to minority groups. Thousands have been displaced so far.

Groups of villagers and their civil society supporters have repeatedly appealed to the Cambodian Government, as well as the companies involved, to halt the construction of the project and to provide appropriate information and opportunities for meaningful engagement. These appeals have not been acted on by the parties concerned.

Business & Human Rights Resource Centre invited project developers China Huaneng Group (parent of Hydrolancang International Energy), Royal Group and Vietnam Electricity to respond to reports by villagers and NGOs raising serious environmental and social concerns; the companies did not respond. We continue to invite the companies to send their responses.

Cambodia: Environmentalists warn of potential risks from hydropower dam construction

Author: Eijas Ariffin, The ASEAN Post

"Are Cambodia’s hydropower plans risky?", 5 February 2019

…, Cambodia’s electricity consumption over the past decade has skyrocketed. In a report by the World Wildlife Fund (WWF),…

… With the Mekong River flowing through the country, it is no coincidence that hydropower is Cambodia’s main source of energy accounting for more than 40 percent of total electricity generation.

…, Cambodian Prime Minister Hun Sen launched the country’s newest hydropower scheme. The 400-megawatt Lower Sesan 2 is said to have cost US$780 million to build and was backed by Chinese funding.

This project is not the only one backed by Chinese money in Cambodia. As part of China’s massive Belt and Road Initiative…

Cambodia’s reliance on hydropower for its energy needs could have a detrimental effect on the country… There is also a growing concern that the construction of these dams could have an adverse impact on the Mekong river. Construction of dams along the Mekong raises immediate risks for fisheries, farming, and food security in Cambodia…

... Environmentalists warn that around 5,000 people, mostly from vulnerable indigenous groups could be displaced by the project. International Rivers, … has said that the dam will have a “costly catastrophic impact on the Mekong River's fisheries and biodiversity".

The Cambodian government is aware of the potential problems associated with hydropower. According to Nao Thuok, a Secretary of State at the Ministry of Agriculture, Forestry and Fisheries, the government is currently operating on projections of a 16 to 30 percent drop in fish biomass…

Cambodia: Stung Treng authorities agree to the ethnic bunong community's request following the impact of Lower Sesan II dam construction

Author: Chakrya Sophak Khouth, The Phnom Penh Post

"Stung Treng authority agrees to Bunong request", 5 December 2018

Stung Treng provincial authorities have unanimously agreed to the request and conditions of the ethnic Bunong community members from Kbal Romeas village who have been impacted by the Lower Sesan II dam in the province…

Stung Treng provincial hall spokesman Men Kong told … that the five conditions set by the 52 ethnic Bunong families from the Kbal Romeas community have been accepted by the authorities and the company behind the dam.

… the Kbal Romeas community’s requests include recognition of the ethnic families’ rights in building houses on the new location they have chosen and the construction of a road, school, health centre and a pond that generates clean water for consumption.

…Like the ethnic Bunong families from Kbal Romeas, the Sre Kor villagers demand authorities include them in the official list of ethnic communities.

… Addressing villagers’ concerns about the lack of clean water, Kong said district authorities have been ordered to make a field visit to the site.

During the dam’s inauguration …, Prime Minister Hun Sen said it would lower electricity costs and put the Kingdom on its way to hooking up every village in the country to the electricity grid by 2002.

A joint project between China-based Hydrolancang International Energy, Vietnam-based EVN International and Cambodia’s Royal Group, the dam will be privately operated before being handed over to the government after 40 years.

The dam has displaced around 1,500 households and flooded tens of thousands of hectares of forest in the province’s Sesan district.

Affected Communities Appeal to the National Assembly: Lower Sesan2 Dam Damages Cambodia’s Rich Natural Resources, Cancel the Project Immediately

Author: 3S Rivers Protection Network (Cambodia)

Community representatives…[traveled] to Phnom Penh…to ask…[the] President of the National Assembly of Cambodia for the assembly’s intervention to immediately cancel the Lower Sesan 2 project…[R]epresentatives express concerns over LS2’s huge negative impacts on rich natural resources, especially fish in Cambodia, including the Great Tonle Sap Lake, and the entire Mekong River…One study predicts that the dam will cause a 9.3% drop in fish stocks basin-wide. This amounts to approximately 200,000 tons of fish per year…Most villagers who will face involuntary relocation by LS2 are ethnic minorities such as Pou Nong, Charay, Kring, Prov and Lao. They have their own cultures that have strong connections to natural resources, especially the land that they have lived on since their ancestors’ times…
