WHAT IS THE IMMEDIATE ENVIRONMENTAL IMPACT? The main environmental impacts are on soil, vegetation, wildlife and landscape. The Hálslón reservoir will submerge an area of 57sqkm and diverting the rivers will impact an area of a further 2,900 sq. km, 3% of Iceland’s land area. Dimmugljúfur, one of the country’s longest and most spectacular canyons, will be partially flooded. About 60 waterfalls and invaluable features will disappear in the reservoir or will be spoilt by river diver- sions. 35 rare moss and lichen species will be affected, two of which are globally threatened. The reservoir will flood an area of vegetation which is used by migratory pink footed geese and reindeer for grazing and breeding. It is feared that the change will mean a local extinction of the reindeer. Below the dam, the decrease in sand carried down to the sea will cause the erosion of the shoreline, where harbour seals and nesting grounds for migratory birds will be affected. These hydrological changes will also have an impact on salmon, trout and char. WHAT ARE THE FINANCIAL CONCERNS? The electricity generated by the scheme has no domestic use for the Icelandic taxpayer who, through the US$ 1.1 billion worth of loans secured by the government, will be ultimately under- writing the cost of the project. Landsvirkjun and the Minister of Industry and Commerce, Valgerður Sverrisdóttir, are confident that the project can enjoy long term profitability. Independent research, however, has shown that at best the project is capable of breaking even. If interest rates increase, the price of alu- minium falls, and the króna remains strong (all of which are projected), then the project will lose over $30 million a year, a loss that will ultimately be met by the already overburdened Icelandic taxpayer. If this happens, then the country will be ef- fectively subsidising Alcoa and will have incurred huge overseas debt for a loss making project. WHAT ARE THE ENVIRONMENTAL CONCERNS? Beyond the immediate environmental impact of building the dam and creating the reservoir, there are deep rooted concerns about the long term impacts of the project. The level of the reservoir will rise and fall by 20 metres or more meaning that on a large area mud and silt will be exposed on the banks during the low water periods. As the mud dries, the strong and frequent winds prevalent in the areas will pick up and scatter material, like talcum powder, over the surrounding countryside, damaging vegetation and habitats and causing further erosion, which could ultimately lead to a “Dust Bowl”. The aluminium smelter will emit 3,900 tonnes of sulphur diox- ide into the atmosphere per year. This equates to an emission of 12kg/ton, whereas the United States Environmental Protection Agency allows only 8kg/ton and the WHO guidelines for Eu- rope define a limit of 5kg/ton. This is in addition to high levels of fluoride and other gasses. The dam is built close to one of the most volcanically active and unstable areas of the earth’s surface. The Vatnajökull glacier is reducing in size due to climate change and as a result, the earth’s crust is uplifted by between 1 and 2 cm per year, which could cause fracturing beneath the dam in years to come with disastrous results.
