New Delhi, July 27 - Members of Orissa's Kondh tribe Monday gathered for a candle light vigil in the capital, urging Prime Minister Manmohan Singh to stop mining of the bauxite-rich Nyamgiri hills in their state.

According to the tribesmen and others supporting them, the mining of the Niyamgiri hills will lead to massive deforestation, affect water resources, destroy the local ecosystem and endanger wild animals commonly found in the area like tigers, leopards and elephants.

The mining will destroy the traditional way of life that indigenous communities like the Kondh tribe lead in the Niyamgiri hills, they said.

Damki Majhi, a tribesmen, said: 'If the mining starts, we can't stay there any more. Our streams, forests and crops will be destroyed...we are dependent on Niyamgiri for water.'

'We cannot eat money and we know it won't last long,' he added.

Among the various organisations supporting the Kondh tribe's cause and joining in the tribesmen's protest is the international aid agency, Action Aid.
