Ivory destruction Despite efforts to destroy ivory, criminals are becoming more organised, ingenious and dangerous. "We have seen more and more organised crime networks moving into the wildlife trade," says Davyth Stewart from Interpol, the international intelligence agency. "Groups who have been traditionally involved in drug trafficking, fire arms and human trafficking are now moving onto wildlife." It's clearly not a fair match: conservationists pitted against criminal gangs. But the wildlife experts say it's a fight they have to take on. They have gathered at the Zoological Society of London to tackle how to halt the rapidly growing trade in animals. The backdrop to these crisis talks is bleak. Thousands of rhinos, elephants, tigers and others have been slaughtered, becoming part of an illegal market that's worth an estimated $19bn a year. Many criminals see it as low risk, high profit, says Mr Stewart. "There is a lower risk of apprehension, it's unfortunate but law enforcement has not invested the resources in attacking wildlife crime as it has in other crimes," he explains. "Even in courts the penalties are much lower. Just last year in Ireland, we saw two people arrested for smuggling rhino horns worth half a million euros. They received a 500-euro fine." Demand and supply John Sellar, the former chief of enforcement at Cites (the Convention on International Trade in Endangered Species), says the focus of the battle should be shifted away from conservation towards the issue of criminality. "It's about locking up the bad guys," he tells the conference.

India village in Rajasthan relocates to protect tigers

An entire village has been relocated in the northern Indian state of Rajasthan to protect tigers, officials say.

More than 350 people from 82 families in Umri village, in the Sariska tiger reserve, moved to a new location.

The number of tigers in Sariska had dwindled to zero before growing to five over the last three years.

Tiger numbers have shrunk alarmingly in India in recent decades. A 2011 census counted about 1,700 tigers in the wild.

A century ago there were estimated to be 100,000 tigers in India.

Compensation

Umri is the second village in Sariska to be relocated to help secure a proper habitat for tigers to increase their numbers. The villagers moved last week.

There are 11 villages with a population of nearly 2,500 people located in the heart of the tiger reserve which need to be relocated to improve the habitat, Rajasthan's chief conservator of forests, PS Somasekhar, told the BBC.

People living in these villages mostly belong to pastoral tribes.

Mr Somasekhar said efforts were being made to relocate four more villages over the next few years.
