Flooding, skin rashes, stomach problems, drownings of both people and livestock,
and a decline in fish stocks: these are among a myriad problems recorded in Stung
Treng as a result of Vietnam's Yali Falls dam, according to a new report.
Angry Stung Treng villagers meet to protest plans for a second dam on the Se San river, the source of their livelihoods.
The community-based study found that more than 50,000 people living in Stung Treng
and Ratanakkiri have been either "seriously or moderately" impacted by
the dam, which stands on the Vietnamese side of the Se San river.
The river is one of the Mekong's largest tributaries. It begins in Vietnam's Central
Highlands and southern Laos before winding from east to west through Ratanakkiri
and Stung Treng.
While the effects of the dam in Ratanakkiri were already well known, the study found
the dam has caused environmental damage even farther downstream in Stung Treng.
The vast majority of the 30,000 villagers living along the Se San, Sre Pok and lower
Sekong Rivers in Stung Treng have suffered significant negative effects from the
dam, the report states.
The report's author Ian Baird says the long term consequences could be even more
serious.
"The long term impacts are likely to be mainly based on the severe damage done
to the aquatic ecosystem, river hydrology and water quality," says Baird. "Water
levels will not be the same again and neither will the water quality."
Villagers first noticed problems in 1996 when, without warning, water was released
from the 65 square kilometer reservoir in Vietnam and caused flash floods more than
70 kilometers downstream in both Ratanakkiri and Stung Treng.
Since then flooding in both the dry and wet seasons has become an occurrence as regular
as it is unpredictable. It has improved since the hydropower station became operational
but problems still abound. Itchiness, eye irritation and stomach problems are commonplace
with villagers who have contact with, or who drink, the turbid water.
The loss of gardens, livestock, rice fields and fishing equipment to floods, as well
as declining fish stocks, have driven villagers to other unsustainable practices.
"Local people have had to increase wildlife trading, woodcutting [and] cleared
forests to move their rice paddies to higher ground," the report states.
Tapley Jordan, coordinator for Partners for Development's (PFD) Stung Treng office,
says that before the study team began discussing the dam with local villagers they
were bewildered by events.
"It was valuable for them to start hearing information about what's been happening,"
he says.
A coalition of villagers and NGOs has now been formed to study the dam's impact and
battle against the politics of hydropower. Oxfam America, PFD, and the Non Timber
Forest Product project (NTFP) sponsored the research into the dam's impact.
A local NGO, the Culture for Environment and Preservation Association (CEPA), hosted
a workshop June 13 and 14 to disseminate the report to villagers.
Representatives from 30 villages met to discuss the dam's impact. They were outraged
when told that another dam, the Se San 3, was set to begin construction 20 kilometers
downstream from Yali Falls, according to a CEPA press release.
"What more can they do to us?" a local village woman asked the meeting.
"Nearly everything has already been destroyed. If they build another dam there
will be even more destruction. More people will die."
No environmental impact assessment (EIA) was carried out for Cambodia when the first
dam - Yali Falls - was built. With the proposed Se San 3 the Vietnamese electricity
company considered its impact as far downstream as Voen Say in Ratanakkiri, but not
that on Stung Treng. Construction on the $273 million dam began June 15, the Vietnam
News Agency reported.
Critics argue that large dam projects have led to environmental disaster for the
people who depend on the Mekong sub-region's extensive river network for their livelihoods.
"Building hydro-dams usually costs far more than budgeted and the dams produce
less electricity than the estimates," says Malena Karlsson, environmental advisor
to CEPA.
Construction on the Yali Falls dam began in 1993, and the final turbine was installed
in December last year. It is the largest hydro-power dam in the region, with a budgeted
cost of $1 billion and a generating capacity of 720 megawatts.
The World Bank lent the project its support in November 2001 when it announced a
plan to fund a transmission line from Yali Falls to southern Vietnam.
When the original EIA was conducted with Swiss government funding by Swiss consulting
firm Electrowatt Engineering, the study was limited to the effects only as far as
eight kilometers from the dam site.
Baird maintains that the Swiss consultants and the Interim Mekong Committee (now
the Mekong River Commission), which coordinated the EIA, must take responsibility
for the inadequate assessment.
Had those organizations included the full environmental and economic impact of the
dam, he says, the promise of cheap, clean electricity would have looked far less
viable.
The report estimates that the loss of rice production caused by flooding has cost
villagers $1.8 million over the past six years, while a further $1.8 million was
lost in the form of damage to stored rice, boats, houses, drowned livestock and so
on.
The dam could be better managed, says Baird, but not without economic costs to the
dam operators. He maintains that flooding could not be avoided entirely, but if water
were released in a way that mimics natural hydrological patterns that would "reduce
aquatic impacts, including impacts on fish".
"Management could be focused on more downstream flooding but that would cost
money in terms of power generation in Vietnam and it seems unlikely that this would
happen easily," Baird says.
The villagers in Stung Treng are more categorical. They simply want the dam dismantled.
"We want to break the dam. The dam may have cost a billion dollars, but the
lives of Cambodians are worth more than that, and how can they compensate for a life?"
asked one woman from Buong village.
The villagers also did not view the gain in electricity as adequate compensation
for the loss of their livelihoods.
"If we have electricity and we are still hungry, should we just look at the
light? Will that fill our stomachs?" asked a woman from Khamphoun village. "We
can survive without electricity but we can't survive without rice."
The report also takes a swipe at the MRC suggesting that the Yali Falls dam would
be a perfect opportunity for the body to prove its usefulness.
"To date the MRC has failed to effectively coordinate with regard to downstream
impacts," the report states. "The MRC only began to consider the downstream
impacts of the dam after press coverage regarding the plight of the impacted villagers
in Ratanakkiri province was released in March 2000."
The following month the MRC arranged a meeting between Vietnamese and Cambodian authorities
to discuss dam management. The Vietnamese authorities agreed to release water only
gradually and to notify Cambodia first.
Baird maintains that while the MRC established a dialogue committee to discuss Se
San river issues, the discussions have not led to any benefits for the affected Cambodians.
The MRC was unable to respond to the allegations by press time.
If the Vietnamese authorities indeed alert their Cambodian counterparts about the
release of water, it comes as a surprise to villagers in Stung Treng.
"No, we never hear any information [about the release of extra water into the
Se San], " says PFD's Jordan. "That information never gets out into the
village."
After such a massive investment it seems unlikely that the Vietnamese will "break"
the dam, as the villagers hope. Baird says that while some villages in Ratanakkiri
have moved to upland areas, that is not a viable option for most.
"Many would like to be compensated for past impacts as well as for future impacts,"
he says. "[However] some are wary of accepting compensation for fear that it
implies they accept the dam, and in fact they do not.
"People would really like it to be decommissioned. However if this is not possible,
then compensation along with mitigation measures to make the flow of the Se San river
more like it was before would be appreciated."
