Controversial dam removals founded on value conflicts
Date:2/22/2013

Researchers at Ume University in Sweden conclude that public opposition to dam removal is not based on knowledge deficiency, as is sometimes argued in dam removal science. It is instead a case of different understandings and valuation of the environment and the functions it provides. The findings are now published in the journal Ecology and Society.

Dam removal is an increasingly common practice as old splash dams and small hydropower dams have become obsolete. Although the removal of these dams has ecological benefits by restoring rivers to their former courses, local residents sometimes contest dam removals.

"We wanted to understand how the proponents and opponents of dam removal think about the function of two contrasting ecosystems an existing dam with a pond and a potential running stream without the pond. The local people who fight to have a dam remain in place have often been dismissed as unknowledgeable," says Dolly Jrgensen, environmental historian at the Department of Ecology and Environmental Science.

Together with ecologist Birgitta Malm-Renflt, she investigated the types of arguments made for and against dam removal in newspaper articles about dams in the Swedish towns Alby, Hallstahammar, Orsa, and Tallsen.

They found that those who want to remove the dam place a high value on the return of game fish to the ecosystem, recreational fishing, and restoration in general. Opponents want the dam to remain because of recreational opportunities for bathing and beaches, the aesthetics of the pond's still water, and the cultural heritage of the pond and the historic dam.

"The public opposition is not based on knowledge deficiency, where more information would lead to better ecological decision-making. The locals simply value different aspects of the environment than scientists or environmentalists that want the dam removed, " says Dolly Jrgensen.

As the number of dam removal projects continues to grow in Sweden and other places in the world, controversies are likely to become more common. Because a decision to remove or keep the dam will result in one side losing the ecosystem services they value, compromise solutions may be difficult to reach.
