    Research for resilient forest landscapes

    SUSTAIN

    Brazil nuts as part of a global sustainable food system

    SUSTAIN is a research project of ETH Zurich, CIFOR and Bioversity International, and is supported by the World Food System Center. We officially collaborate with the Peruvian organizations IIAP, UNAMAD and PROFONANPE. Our research is aimed at gathering evidence to support sustainable supply chains of Brazil nuts from Peru to Switzerland.

    Brazil nuts

    An economically important forest product

    The Brazil nut is a giant tropical rainforest tree found in Brazil, Bolivia and Peru. Harvested from the wild, the nutritious nuts are one of the most economically important non-timber forest products in the world. Annual exports of Brazil nuts are valued at tens of millions US dollars, but only a small fraction are sourced ethically through certification.

    Harvesting the nuts

    An important element of rural livelihoods in the Amazon

    Brazil nut harvesting is a crucial part of rural livelihoods across the Amazon region. The same rural communities also depend on timber harvesting from the same forests to keep them above the poverty line. Forest degradation, as a consequence of unplanned intensive timber harvesting, has potentially negative consequences for Brazil nut production, biodiversity conservation, and climate change.

    Our aims

    Research that contributes to a global sustainable food system

    We focus on the Madre de Dios region of Peru, which contains 26,000 square kilometers of the most biologically diverse, carbon dense, Brazil nut-rich forest in South America.

     

    Our specific research aims are:

    • Develop a better understanding of the effect of forest degradation on the reproductive ecology of the Brazil nut tree
    • Use this better understanding to improve Brazil nut management
    • Develop a better understanding of the barriers harvesters face to adopt certification and export standards
    • Provide COOP information about the options for a resilient and sustainable supply chain of Brazil nuts from Peru

    Through these endeavors we will provide a novel and powerful contribution to the global sustainable food system.
