Why It Matters
Indigenous peoples manage or hold tenure over approximately 25% of the world's land surface. A widely circulated claim attributes 80% of the planet's remaining biodiversity to these territories, but a 2024 Nature commentary found this figure is unsupported and likely originates from a misquote—biodiversity as a concept spans genes to ecosystems and cannot be quantified as a single percentage. What is well-documented is that these territories contain 37% of remaining natural lands worldwide, and biodiversity decline is consistently less severe on Indigenous lands than in comparable non-indigenous ecosystems. This is not a coincidence. Indigenous knowledge systems (IKS)—accumulated over millennia of sustained observation, experimentation, and adaptation—represent some of the most successful long-term strategies for managing complex ecosystems. Fire management practices of Aboriginal Australians. Salmon conservation protocols of Pacific Northwest First Nations. Polyculture farming systems of Mesoamerican peoples. Water harvesting techniques of Saharan communities.
Western science is increasingly recognizing what Indigenous peoples have long known: that these knowledge systems contain sophisticated ecological understanding encoded in practices, narratives, languages, and governance structures that differ profoundly from Western scientific conventions but are no less rigorous in their capacity to sustain human-environment relationships over deep time.
Yet integration is fraught. The history of Western science's engagement with Indigenous knowledge is largely one of extraction—taking useful elements while ignoring the cultural, spiritual, and governance frameworks that give them meaning and ensure their appropriate use. The 2024-2025 literature reflects a field grappling seriously with how to achieve genuine knowledge partnership rather than knowledge extraction—recognizing that this requires changes in Western scientific institutions, not just additions of Indigenous content.
The Science
Braiding TEK and Western Science in Freshwater Management
Maliao and Tothmeresz (2025), with 1 citation, present a systematic map protocol for evaluating how Traditional Ecological Knowledge (TEK) and Western science are braided together in freshwater social-ecological systems management. Their methodological contribution is significant: rather than simply collecting examples of integration, they systematically evaluate the quality, depth, and outcomes of integration efforts.
The protocol draws on the "Two-Eyed Seeing" framework developed by Mi'kmaw Elder Albert Marshall—seeing from one eye with the strengths of Indigenous knowledge and from the other eye with the strengths of Western knowledge, and using both together. This metaphor captures a key principle: integration does not mean merging two knowledge systems into one, but maintaining their distinct perspectives while allowing each to inform the other.
The freshwater context is particularly relevant: Indigenous peoples worldwide have developed sophisticated understanding of water systems—seasonal flow patterns, water quality indicators, fish behavior, riparian ecology—that complements but differs from hydrological science. The IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) has formally recognized TEK as a legitimate knowledge system alongside Western science, creating institutional space for this braiding.
Decolonizing Environmental Education in Africa
Shabalala (2025), with 6 citations, argues that environmental education in Africa must be decolonized through the early integration of indigenous knowledge systems. The current curriculum in most African nations teaches Western environmental science as universal truth while treating local ecological knowledge as folklore—a colonial residue that undermines both educational effectiveness and cultural continuity.
The study proposes guided by "Zibanjwa Zisemaphuphu"—an Indigenous philosophical framework for environmental stewardship—that IKS be integrated from the earliest stages of education, not added as a supplement to a Western science foundation. This is a structural argument: if Western science is taught as the default framework and IKS as an alternative, the power hierarchy is reproduced regardless of how respectfully IKS is presented.
Practical recommendations include: training teachers in IKS content and pedagogy (most African science teachers are trained exclusively in Western methods), developing curricula that present ecological concepts through both Western and Indigenous frameworks simultaneously, and involving local knowledge holders—elders, traditional healers, community farmers—as co-educators in formal school settings.
Traditional Conservation and Modern Ecological Management
Saha et al. (2025) examine how Indigenous knowledge systems contribute to conservation practice and how they can be integrated with modern ecological management. Their analysis spans multiple continents, documenting IKS contributions to biodiversity conservation (sacred groves in India, totemic species protection in Australia), sustainable resource harvest (rotational fishing in Pacific Islands, forest gardens in Southeast Asia), and ecosystem monitoring (Indigenous fire indicators, animal behavior-based weather prediction).
A key finding: Indigenous conservation practices are often more effective than externally imposed protected area management because they are socially embedded—enforced through cultural norms, spiritual beliefs, and community governance rather than through external regulation and enforcement. When community governance structures are undermined (through colonization, displacement, or modernization), conservation effectiveness declines regardless of the formal protection status of the land.
The practical implication for modern conservation: supporting Indigenous governance and land tenure is not merely a social justice measure—it is a conservation strategy. The most biodiverse landscapes on Earth are managed by Indigenous peoples not despite but because of their governance systems.
IKS in STEM Education: Zimbabwe
Sunzuma et al. (2025), with 3 citations, examine the integration of Indigenous Knowledge Systems into STEM education from a Zimbabwean perspective. The book-length study addresses both theoretical foundations and practical implementation challenges for creating inclusive science education that reflects cultural diversity.
Key challenges identified: Western STEM education operates on epistemological assumptions (objectivity, universality, reductionism) that conflict with IKS epistemology (relationality, context-dependence, holism). Integrating IKS into STEM is not merely adding examples—it requires questioning fundamental assumptions about what counts as scientific knowledge, what constitutes valid evidence, and who has authority to produce knowledge.
Practical innovations include: using traditional basket-weaving to teach geometric principles, using Indigenous weather prediction systems to introduce climate science concepts, and using traditional food preservation techniques to illustrate chemistry and microbiology. These are not tokenistic additions but genuine alternative entry points into scientific understanding.
Integration Models Comparison
<| Model | Approach | Strength | Risk |
|---|---|---|---|
| Two-Eyed Seeing | Maintain both perspectives, use both together | Preserves integrity of both knowledge systems | May avoid difficult epistemological questions |
| Integration | Merge compatible elements into unified framework | Practical for specific management problems | May extract IK from cultural context |
| Parallel Systems | Maintain separate systems, compare conclusions | Respects autonomy of both systems | May not achieve practical synthesis |
| IK-Led | Indigenous frameworks primary, Western science supplementary | Centers Indigenous authority | May face institutional resistance |
| Co-Production | Joint development of new knowledge through collaboration | Produces novel insights neither system alone generates | Requires long-term trust and equitable power |
What To Watch
Three developments will shape this field in the near term. First, Indigenous data sovereignty movements are establishing governance frameworks for how Indigenous knowledge is collected, stored, shared, and used—including the right to refuse access. The CARE Principles (Collective benefit, Authority to control, Responsibility, Ethics) complement the FAIR Principles (Findable, Accessible, Interoperable, Reusable) that govern scientific data. Second, climate change is creating urgency: as ecosystems shift into novel states that Western science has no precedent for, Indigenous knowledge of past environmental variability becomes uniquely valuable. Third, national and international policy frameworks (IPBES, CBD Kunming-Montreal Global Biodiversity Framework) are creating institutional requirements for IKS inclusion that go beyond voluntary goodwill. Watch for whether these policy mandates produce genuine partnership or bureaucratic box-checking.
