When Argentinian oil company CGC began seismic testing on their ancestral land – in one of the most remote and pristine areas of the Ecuadorean Amazon – it was the women of the Sarayaku community who decided to take a stand against Big Oil.

“As mothers, we were concerned about our children and our land,” Noemi Gualinga told me.

The 44-year-old is one of the leaders of the decade-long fight over land rights between the Sarayaku, who number some 1,200 people, and CGC and the Ecuadorean government.

Invited by Amnesty International to attend the launch of their annual report in London this week, Gualinga, wearing a colourful traditional dress, described her community’s struggle.

She explained how in 1996, CGC oil company was granted exploration rights by the government, without the consultation and the agreement of the local indigenous population.
