Climate change and environmental degradation are impacting the food sovereignty of Indigenous communities in Cotacachi, Ecuador. With diminishing stream water and uneven rainfall patterns, local farmers identify climate change as one of the most significant factors impacting agriculture. Moreover, environmental factors like deforestation, mining, and soil degradation, and socioeconomic factors like land ownership and commercial agriculture have brought substantial shifts in the food systems of Indigenous communities. Against this backdrop, communities in Cotacachi are using Indigenous knowledge and practices to ensure food sovereignty. The research systematically explores how this ecological knowledge is essential in adapting their food systems to climate change while contributing towards climate mitigation through carbon sinks. This includes exploring the Indigenous approach of Andean Chakra, which uses intercropping and contributes to the diversity in food systems, the linkage of food with cultural identity, and sacred rituals and celebrations like Inti Raymi, the harvest festival.
