MARSEILLE • Should 80 per cent of the Amazon rainforest be declared a protected area by 2025?

The world's top conservation body was poised to decide on Sunday whether its 1,400 members can vote on this controversial proposal, put forward by indigenous groups.

Submitted under an emergency provision to the International Union for the Conservation of Nature (IUCN), the measure calls for a "global action plan" to halt rampant deforestation and the destructive extraction of precious minerals and oil.

Over the past two decades, the Amazon has lost roughly 10,000 square kilometres every year, according to assessments based on satellite data.

"That's the emergency, not just for us but for humanity," Mr Jose Gregorio Diaz Mirabal, a leader of the Curripaco people in Venezuela, told Agence France-Presse at the Congress venue in Marseille.

For the first time in the IUCN's 70-year history, indigenous groups are now voting members alongside government agencies and national or international non-governmental organisations.

Mr Diaz Mirabal submitted the Amazon proposal for the organisation COICA, which represents more than two million indigenous people in nine Amazon nations.

"We have been neglected, and now we have a voice and will exercise that voting right," he said.

Recent research has warned that massive destruction of tropical forests and the effects of climate change are pushing the Amazon towards a disastrous "tipping point" which would see tropical forests give way to savannah-like landscapes.

This would not only drastically change the region's climate, but have an impact on global climate systems as well, scientists say.

Rates of tree loss drop sharply in the forests where native peoples live, especially if they hold some degree of title - legal or customary - over land, other research has shown.

IUCN officials are reviewing the COICA measure, together with 20 other proposals submitted after the deadline last year, "to make sure that they are both 'new' and 'urgent'," said Mr Enrique Lahmann, a senior administrator.

"Both criteria are required." A decision was to be announced late Sunday or yesterday, his office said.

While the vote, which would be held in the coming week, would not have legal weight, it demonstrates the strength of feeling among indigenous groups.
