Ecuador prepares for ‘once-in-a-lifetime’ vote to stop oil drilling

Referendum alongside presidential election will decide whether to halt extraction in Amazon national park

As Ecuadorians go to the polls on Sunday they must not only decide between eight presidential candidates but also vote on an unprecedented referendum question that could set a new course for the oil-reliant nation.

The poll will decide whether to halt drilling at the Yasuni Ishpingo-Tambococha-Tiputini (ITT) oilfield, also known as oil block 43, which lies in an Amazon national park and one of the world's richest pockets of biodiversity. Ecuador's largest protected area is also home to the Waorani people and the country's last Indigenous communities in voluntary isolation, the Tagaeri and Taromenane.
