Referendum result protecting Yasuní reserve will benefit huge range of species as well as ‘uncontacted’ Indigenous peoples

Ecuadorians have voted in a historic referendum to halt the development of all new oilwells in the Yasuní national park in the Amazon, one of the most biodiverse regions on the planet.

Voters opted to safeguard the unique biosphere by a margin of nearly 20% with more than 90% of the ballot counted – with more than 58% in favour and 41% against, according to Ecuador’s National Electoral Comission. Voting took place in the first round of presidential elections on Sunday.

The move will keep about 726m barrels of oil underground in the Yasuní national park, which is also home to the Tagaeri and Taromenane people, two of the world’s last “uncontacted” Indigenous communities living in voluntary isolation.

At a time when the climate crisis is intensifying around the world and the Amazon rainforest is fast approaching an irreversible tipping point, Ecuador has become one of the first countries in the world to set limits on resource extraction through a democratic vote.

In a second referendum, citizens in Quito also voted to block gold mining in the Chocó Andino, a sensitive highland biosphere near the capital city, by an even larger margin of about 68% to 31%.
