October 9, 2008: A plan to build a soda ash factory on Lake Natron in Tanzania has been dealt another blow following its rejection by more than 250 scientists.
The scientists who were attending the 12th Pan African Ornithological Congress (PAOC) in South Africa said Lake Natron was a Ramsar site that should be protected.
This has added more pressure on the Tanzanian government to put aside the project and has increased the level of awareness internationally, said Mr Ken Mwathe from Birdlife International, one of the environmental groups opposed to the project.
The Ramsar agreement requires countries to seek consensus with other countries on issues which affect shared resources.
Tata chemicals, Indias largest business conglomerate plans to build a factory capable of processing 500,000 tonnes of soda ash annually at the lake.
Along with the plant, the firm which owns majority shares in Magadi Soda Company, plans to construct tarmac access roads, a pipeline to carry soda slurry across the lake and living accommodation for and estimated 1,225 construction workers and 152 permanent staff.
According to the National Development Corporation of Tanzania, Lake Natron brine contains at least eight per cent sodium chloride.
It is supplied by hot springs of volcanic origin and by fumerolic emanations from Ol Donyo Lengai.
