Regional Journalists Examine Impacts of Don Sahong Dam on Dolphins, Fisheries, Villagers

Journalists from across the Mekong region met villagers, government officials and NGOs to understand and write stories about the costs and benefits of the Don Sahong dam. Mekong Partnership for the Environment partner Cambodia Institute for Media Studies convened 20 local and four regional journalists in Stung Treng from May 26-28 to learn about the dam and it’s effect on communities, the environment and the dolphin and fish populations.

Don Sahong vs Dolphins: How the Dam Is Affecting Local Residents

Dam Chan handed over the food in exchange for riel as she described hearing the loud bangs of dynamite in the distance.

The 55-year-old has farmed and sold food in Preah Rumkel commune her entire life and is concerned about the future of her home now that construction on the nearby Don Sahong Hydropower Dam has started to affect the local wildlife, and subsequently the lives of those residing near the Lao border.

Mekong dam a threat to rare dolphins – and villagers too

THE DON SAHONG hydroelectric dam threatens the last 80 Irrawaddy dolphins in the Mekong River – as well as the livelihoods of the people downstream in Cambodia, who depend heavily on the river’s resources.

The people in Preah Romkel village of Stung Treng province claim their way of life is in danger. The eco-tourism that boosts the local economy will be destroyed if the endangered Irrawaddy dolphins are driven into extinction by the impact of the new Don Sahong Dam on the Laos-Cambodian border.

Dolphin calves born in the Mekong

The Mekong River now has so many dams that one of the world’s mightiest rivers could almost run dry. In the dry season, river levels do in fact become dangerous for the rare river dolphins, Orcaella brevirostris Illegal fishermen and stranding opportunities increase, but the good news this March, as river levels rise again, is that no animals were lost and 3 calves were born near the delta. 688 river guards protect the dolphins and the river in Cambodia and the Lao PDR, and that investment surely must be helping! The WWF report the story here.

Many plants and animals rely on the might flow of the Mekong, with 1100 fish species alone, thousands of insects, mammals, amphibians, birds and reptiles well-known to researchers. The dolphins feed on fish, cephalopods and crustacea, facing intense competition from humpback and bottlenose dolphins when at the coast. Perhaps the 90 or so dolphins in Lao PDR and Cambodia can act as suitable emblems of the extinction possibilities threatening the rainforest and the riverine species. This dolphin is classed as Vulnerable, according to the IUCN Red Book classification, like many others of its order and so many others in the rapidly disappearing habitats around SE Asia.

Mekong Dolphin Extinction, Hydropower and Climate Change

Scientists for the Mekong offer this article to inform the public, the delegates at COP21, and decision-makers worldwide about the impacts of hydropower development on the Lower Mekong River, and the serious repercussions for 60 million people in SE Asia. This article provides an overview of the many significant environmental and social impacts of hydropower dams on the Mekong River basin.

Dolphin Numbers Fall, but WWF Still Hopeful

Over 400 people joined in WWF’s “Dolphin Day” celebration in Kratie town Tuesday morning, parading in dolphin-emblazoned T-shirts up the riverfront and through the market. Though local enthusiasm is palpable, the bottom line is sobering. The number of endangered Irawaddy dolphins in the Mekong River continues to drop, the WWF announced in a press conference following the celebration. A population that once numbered in the hundreds has now fallen to just 80 adult animals.
