A report by Nordic hydro consultants warns that a comprehensive change in food production culture may be needed in Cambodian villages negatively affected by hydro operations upstream in Vietnam.

The study funded by the Swedish International Development Agency (Sida) predicts that hydro dams on the upper Srepok River in Vietnam will reduce fish stocks and make riverside agriculture impossible, with major negative impact on people's diets and livelihoods, especially the poorest households.

A draft final version of the study, "Environmental Impact Assessment on the Cambodian part of Srepok River due to Hydropower Development in Vietnam", was obtained by NGO Forum on Cambodia from the Swedish International Development Agency, which provided funding.

An estimated 11,000 people, mostly ethnic minorities, live along the Cambodian stretch of the Srepok River, and depend upon the river for fishing, drinking, household use, irrigation, livestock and transportation.

All these uses will be seriously disrupted by a series of dams Electricity of Vietnam plans to build on the Srepok within five years, according to the study by SWECO Groner of Sweden.

The largest dam, 280-MW Buon Kuop, has been under construction since 2003 and is expected online in 2008.

The study notes that food security is good for most of the riverside population. No children are undernourished due to the abundant fish in the river, providing the main protein sources. In most villages, households have enough cultivation land and even produce a rice surplus, which together with fish and animals can regenerate cash.

But protein deficiency especially in growing children can be anticipated since there seems to be no available alternative to replace fish as a major protein source, as wildlife hunting is regulated and domestic animals are raised mainly for selling and not for family food. The study concludes that a comprehensive change may be required in the riverside villages.

Unless mitigated, the expected fish decline in the river will have a major negative effect on the economy of fishing households, especially the poorest.

The solution, according to SWECO Groner, is: Changes both in the food habits (eating meat more often) and in economic resources (other sources of cash, or more efficient animal raising, demanding more pasture land, extension and training input and introduction of new fast-growing species, e.g. rabbits), to guarantee the future nutrition status of the riverside people.

Alternatively, Electricity of Vietnam could change the way its hydro dams are operated. The study notes that "daily peaking" is the most environmentally damaging mode of operation.

"A major reconsideration of dam operating schedules might be needed," writes SWECO Groner, "in order to avoid destructive effects on downstream areas."

The only way of trying to save as many [fish] species as possible is to try to keep [the river] as close as possible to the natural conditions, it says.

SWECO Groner also recommends building a specially-designed re-regulating dam near the Cambodian border that could even out flows to downstream Cambodia.

Sida has agreed to a public review of SWECO's recommendations in Phnom Penh later this year.

SWECO Groner is a subsidiary of SWECO, Sweden's leading engineering consulting firm and longtime hydro adviser to Electricity of Vietnam.

they have to move to the cities or make other villages

hmm, so this is gonna be part of another "evil" Viet plot to destroy Cambodia, right?

Not really something to be sarcastic about. Environmental issues and politics should not overlap.

Sometimes there have to be sacrifices to make economic gains.

dam............

Oh really? I've heard accusations about how the Vietnamese gov't. dumped toxic wastes to "purposefully" blind Khmer Krom and placed polluting industries in villages and rural areas in an effort to endanger Khmer Krom's health. Additionally, basic health care was denied to worsen Khmer Krom's health as part of the "genocide."

So I can definately see how this dam issue could be exploited in the same way. It will be an "evil" Viet "genocidal" plot to dwindle the food supply causing Khmer starvation. The next thing will be invasion.

keyword here is "heard", you're basing these example off of something you've heard and not factual evidence...sorry you have no credibility

^ Of course, it's straight from the Khmer Krom propagandists and their websites.

p.s. I don't care what you think of my credibility.

^But this article is NOT from a KK website; not likely propaganda.

doesn't mean that they can't exploit the issue as part of a "evil" plot.

I don't know about that, but it certainly is bad news. I can understand how you are frustated at all the accusations and such, but please don't take it out of proportion and do the same on Khmers.

sometime countries have to make somesacrifices for economic deveopements. look at china and the three gorges dam, they have to relocate thousands of people. Vietnam Hydro Dams will help not only vietnam, but that whole indochina peninsula. I believe that one day the indochina will be an economic power in asia....

Umm...I believe the title states that "Vietnam hydro dams threaten Cambodian food security"...How is that beneficial to Indochina, particularly, Cambodia? It's okay to benefit out of someone else's misery? Apparently, you don't understand the effects of this hydro dam. The water conditions downstream will be affected. And if water conditions changes, the natural habitat for fish species will be affected which may lead to other environmental catastrophies and hardships. Of course the riverside population there will have to suffer even more. But why would vietnam care? it's not THEIR people. A little sacrifice won't hurt.

for a while Vietnam have to import electricity from China at a high price, because of the short supplies. this dam is going to allow Vietnam and perhaps neighboring countries to have electricity at a much lower rate....

cheaper electricity, at the costs of the livelihood of the people... sheesh...

also lets not forget the extinction of various species in the mekhong

Vietnam will pay for the energy.

an easy solution is to is to build a dam near the source of the river in mainland cambodia .. maybe that way food supply wont be threatned ...

dams are good source for generation electricity, but they fu-k up the environment like hell ..
