Rosa Shiguango is a Kichwa leader from the Ecuadorian Amazon and a lead plaintiff in her people’s landmark legal case demanding justice after one of the region’s worst oil spills in decades. Her community, Amarun Mesa, is among more than 100 Indigenous communities affected by the spill of over 15,000 barrels of crude oil in 2020, caused by the rupture of two major pipelines. The disaster contaminated the Coca and Napo Rivers—vital waterways for Indigenous communities and ecosystems in one of the most biodiverse regions on the planet. In response, Rosa joined other Indigenous women and leaders in filing a constitutional lawsuit against the Ecuadorian state, seeking justice, environmental remediation, and reparations for affected communities. Fiercely outspoken, Rosa has been a powerful voice denouncing state negligence, corporate impunity, and the ongoing disregard for Indigenous peoples’ rights, health, and lives. Her leadership stands at the intersection of Indigenous rights, environmental justice, and women’s leadership in the defense of the Amazon. Photo Credit to Ramiro Aguilar Villamarín.
