“Jatun Yacu” is the indigenous name, in Quechua language, for one of the tributaries of the Amazon river in Ecuador. As the Amazon river flows from its source to the Atlantic Ocean, it crosses four countries with different legal systems. This pilot documentary film traces the ebb and flow of rights in and of the Amazon across space and time, ethnographically exploring the question of what it means for a river to have rights, where these rights come from and what they might look like visually. It aims to show that while the notion of rights of nature may seem exotic to Western legal minds at first glance, a closer look reveals that the idea that non-human entities have rights is not new.
