Accessing healthy and affordable food is highly intertwined with the biggest challenges of our century, such as climate change or conflict resolution. The United Nations has established eliminating hunger as one of the seventeen goals of the international community to achieve sustainable development. The largest part of the food the world consumes is produced by smallholders, peasants and Indigenous communities, but their own food sovereignty is not always practically implemented. This paper explores the extent to which Indigenous Peoples in the Ecuadorian Amazon are able to practice food sovereignty, and traces colonialism’s continuous influence on the application of international law to this marginalized community. Though the Indigenous concept of Buen Vivir is linked to food sovereignty and was integrated into the Ecuadorian constitution since 2008, post-neoliberalism, land ownership issues, access to seeds, the use of chemical fertilizers within agriculture, and tourism in the Amazon are all elements impeding its realization.
