"The Jarawa are vulnerable to exploitation by outsiders, and poachers are known to lure young Jarawa women with alcohol or drugs to sexually exploit them," Survival International, a global movement for tribal peoples' rights, that has campaigned on the issue of 'human safaris' said in a release.
"Hundreds of tourists continue to pass through the reserve on a daily basis, disturbing the game the Jarawa hunt for their survival, and effectively treating the Jarawa like animals in a zoo," it said.
"In 2013, the Andaman authorities promised the Indian Supreme Court that they would introduce an alternative sea route by March 2015, but building work has not yet started. Plans have also been announced to widen the Andaman Trunk Road (outside the reserve) and build two new bridges," it said.
The organisation said it has been five years since the "human safaris" were first exposed by Survival International and over 12,000 people have since pledged not to holiday in the Andaman Islands until the human safaris are stopped.
Survival's Director Stephen Corry said, "The longer the construction of the alternative route takes to complete, the greater the risk to the Jarawa who, like all recently contacted peoples, face catastrophe unless their land is protected.
