In the indigenous community of Sikamabiu located in the Yanomami Territory, a sustainable agricultural practice known as "fertirrigação" is being implemented. This system involves reusing water from fish farming tanks to irrigate fields growing cassava, potatoes, and rice, which not only helps in food production but also eliminates the need for chemical fertilizers. This initiative plays a crucial role in empowering the indigenous population by providing them an alternative source of food in light of environmental challenges posed by mercury contamination from illegal gold mining in the region.

The project integrates aquaculture, crop irrigation, and poultry farming, responding to the long-standing requests from the community. The Sikamabiu community, comprising around 400 individuals from about 30 families, primarily from the Xiriana subgroup of the Yanomami, has actively participated in the project. A total of 34 indigenous trainees have been educated on all aspects of the initiative, from constructing fish tanks to managing fish populations and using the water effectively for agriculture.

This eco-friendly approach not only bolsters food security for the Yanomami people but also enhances their self-sufficiency amidst ongoing environmental threats. As they move away from reliance on contaminated river fisheries, this project highlights the innovative ways indigenous communities are adapting to preserve their livelihoods while tackling ecological issues.
