India’s Supreme Court has ordered the eviction of over 1.1 million tribal and other traditional forest dwellers, after it recently rejected their ancient ownership claims on jungle land.

Experts estimate that the 20 February legal fiat could result in some 8 million tribal people, including women and children, leaving forest areas spread across 17 Indian states which their ancestors had inhabited for centuries.

The evictions, which are to be executed under official and police supervision, have to completed by 27 July, the date of the next court hearing in the case.

“The judgement is a death sentence for millions of tribal people in India,” said Stephen Corry head of Survival International, the London-based human rights organisation that campaigns for the rights of indigenous peoples.

“It’s land theft on an epic scale and a monumental injustice” he declared, adding that it would trigger an ‘urgent humanitarian crisis’ and do nothing to save the forests which the tribes people have protected for generations.

Other activists fear that such a large-scale eviction could generate social unrest in several states like Madhya Pradesh in central India, Orissa in the east and Karnataka in the south, all with large numbers of tribal people.

The court order followed over 10-years of legal wrangling and came in response to a petition filed by wildlife and nature preservations groups.
