Learning from case studies and discussions at our side event of the 2021 Summit, we highlight the need for concrete entry points beyond merely symbolic acknowledgment of the importance of indigenous knowledge. We identified seven entry points that can contribute to bridging indigenous and academic knowledge about food systems (Fig. 1). The diversity of entry points reflects the need for a multi-pronged approach that includes an improved understanding of indigenous knowledge systems, more inclusive practices of conservation and negotiation, as well as political articulations of indigenous representation and self-determination.

Seven entry points indicates approaches ranging from better documentation and understanding of indigenous knowledge to inclusive practices of conservation and negotiation, to political challenges of marginalizing institutional practices and policies that can contribute to bridging indigenous and formal scientific knowledge for sustainable and inclusive food systems.

Co-evolution of ecosystems and knowledge systems

Indigenous people conserve about 80% of the world’s biodiversity2 and their knowledge systems have co-evolved with ecosystems, guiding agricultural and other livelihood practices. Despite growing academic interest in the co-evolution of ecosystems and knowledge systems3, agricultural development often fails to recognize the adaptive character of indigenous knowledge and practices. Understanding this co-evolution and adaptation is crucial for situating indigenous food systems and their sustainable roles in wider environments4.


As indigenous food systems knowledge is mostly transferred orally, it is particularly vulnerable to socioeconomic and ecological disruptions. The vast majority of indigenous food systems remain poorly documented, further increasing vulnerability to external disruptions and invisibilizing them in debates about the global governance of food systems. Overcoming the marginalization of indigenous knowledge in food systems transitions requires comprehensive documentation both of epistemic resources and of their importance for livelihoods and environmental sustainability.

Loss and resilience

Indigenous knowledge systems are being rapidly eroded. Extensive use of exogenous practices, urbanisation, and global food commodity markets act as mutually reinforcing drivers that foster biodiversity loss, land grabbing, forced displacement of communities and loss of native languages5,6. However, complex patterns of erosion, adaption, and revitalization7 of indigenous knowledge often remain poorly understood by researchers and policymakers. Without accounting for the mechanisms of loss and resilience, policy interventions may adversely affect the preservation and revitalization of indigenous knowledge rather than mitigating its loss.

Strategies for conservation

Academic research on indigenous knowledge benefits indigenous peoples only if it contributes to concrete interventions that support indigenous communities in conserving relationships with local environments. Relationships between people and their environments can only be conserved in-situ. Protecting ecosystems and natural resources while ensuring local communities have access to their lands and rights to practice their culture is essential to maintaining these relationships and must be central to conservation efforts. While indigenous knowledge demands a focus on in-situ conservation, ex-situ methods can play an important supporting role. For example, seeds of local crop varieties in gene banks can play an important role in the transfer of indigenous food systems knowledge between regions and across generations. At the same time, ex-situ methods need to be developed carefully together with communities as they also create novel risks of exploitative bioprospecting and biopiracy.

Negotiating knowledge diversity

Agricultural research and development have historically targeted indigenous food systems as obstacles to economic growth and modernization8. While there is increasing advocacy for the inclusion of indigenous knowledge9, its integration often reproduces inequalities: Indigenous knowledge is recognized only insofar as it has a supplementary value for mainstream agricultural development10. Rather than highlighting the value of indigenous knowledge for indigenous communities, academic research often focuses instrumentally on the usefulness of indigenous knowledge for external agendas in biodiversity conservation or sustainable growth. In contrast, more recent frameworks aim to create frameworks for symmetrical dialogue rather than merely an asymmetrical integration of indigenous knowledge into dominant academic frameworks11,12.

Representation in practices and policy

Contestations of the 2021 UN Food Systems Summit illustrate that the marginalization of indigenous people remains deeply entrenched in major institutions and processes. The global food system continues to be dominated by actors who prioritize formal scientific knowledge-from public funding agencies to the agrifood industry to major non-governmental organizations. Indigenous interest organizations and actors are still often pushed to the periphery of institutional practices and policies. Thus, academic research on indigenous knowledge needs to be combined with concrete mechanisms that reconfigure institutional practices and policies in the food system. Research must connect to practice as transformations of the food system require an active policy stance that challenges the institutional misrepresentation of indigenous knowledge and peoples.

Indigenous self-determination

Different food systems are entangled with different ways of life, highlighting the need to link food security with food sovereignty as it relates to cultural identity, spiritual wellbeing and land stewardship13. The marginalization of indigenous food systems is intertwined with colonial legacies of cultural and political domination14. Food security and sovereignty are therefore part of a wider political struggle for self-determination of indigenous peoples. As endorsed in the United Nations Declaration on the Rights of Indigenous Peoples, self-determination implies the right of indigenous peoples to be in control of their own food systems as part of determining their own way of life15.
