Much of the confusion around Indigenous knowledge doesn’t come from disagreement, but from the way terms are adopted, repeated, and assumed to mean the same thing. This post takes a step back—not to formalize definitions, but to make the language we’re using more intentional, careful, and grounded.
Defining the Term “Indigenous”
To begin, it’s worth slowing down and asking a simple but often overlooked question: what do we actually mean when we use the word Indigenous? As Natasha Tassel-Matamua (2025) notes, the term Indigenous is most often understood in relation to peoples, and less frequently in relation to a shared worldview.
When defined in relation to peoples, the term refers to approximately 476 million Indigenous peoples worldwide, living across more than 90 countries. Together, they represent about five percent of the global population and speak over 4,000 of the world’s roughly 7,000 known languages. This categorization is commonly grounded in long-standing relationships to specific territories. Indigenous communities are recognized as having occupied and stewarded particular lands over extended periods of time, making place, territory, and land-based relationships central to Indigenous identity.
Tassel-Matamua also emphasizes another defining feature of Indigeneity: a shared history of colonization. Although Indigenous peoples are understood as the original inhabitants of their territories, they have been subjected to sustained forms of imposition—physical, spiritual, ideological, political, and economic—by colonial forces. In more recent decades, many Indigenous peoples have embraced the term Indigenous as a way to acknowledge these shared histories of colonization, displacement, sociopolitical marginalization, discrimination, and ongoing experiences of systemic racism. In this sense, the term provides a collective identity and a shared political voice that can serve as a source of empowerment.
At the same time, it is important to note that many Indigenous communities continue to prefer their own names and terms of self-identification. Using a collective term does not mean erasing difference. There is no singular physical trait, cultural practice, or landscape that defines Indigeneity, nor does the term flatten the diversity of Indigenous identities, nations, and lived experiences.
Defining Indigeneity in relation to peoples has also generated challenging debates. Some critics argue that centering Indigenous identity constitutes a form of “reverse racism” that privileges certain groups over others. These arguments often miss a key point: equity and equality are not the same thing. The minority status of Indigenous peoples is not accidental, but the result of colonial histories that continue to shape social, political, and economic realities. Questions around blood quantum, mixed ancestry, or the legitimacy of Indigenous identity further complicate these debates, often reducing Indigeneity to biology while overlooking lived relationships to land, community, and culture.
Indigenous as Worldview
The term Indigenous is also used in another, equally important way: to describe a worldview. A worldview can be understood as the lens through which people interpret reality and make sense of their place within it. While experiences are always shaped by context, many Indigenous communities around the world share relational ways of seeing and being.
Indigenous worldviews often emphasize the inseparability of spiritual and material realms, strong collective and intergenerational orientations, and an understanding of Mother Earth as a living being rather than a resource. Humans are not positioned above nature, but within it—part of complex ecological systems alongside more-than-human relatives. Interconnectedness and interdependence are not abstract ideas here; they are lived principles that guide everyday relationships, responsibilities, and decision-making.
Indigenous Knowledges (IK): An Umbrella Concept
The plural form Indigenous Knowledges is used deliberately. It signals that there is no single Indigenous knowledge system and resists the tendency to treat Indigenous ways of knowing as unified or interchangeable. Instead, Indigenous Knowledges refer to diverse, place-based bodies of knowledge developed over long periods of time and passed down within specific cultural, ecological, and historical contexts.
These knowledges often share relational principles that shape how humans understand their relationships with land, water, plants, animals, and each other. Knowledge is not only about observation or explanation, but about responsibility, ethics, and meaning. In this sense, Indigenous Knowledges function as systems of inquiry in their own right—ways of observing, interpreting, and engaging with the world that differ fundamentally from Western scientific paradigms (Cajete, 1995).
Throughout this blog, Indigenous Knowledges (IK) is used as an umbrella term to refer to these diverse and relational systems of knowledge held by Indigenous peoples across different territories and histories.
Within this broader category, several related terms are often used—sometimes carefully, sometimes interchangeably. Two that appear frequently are Traditional Ecological Knowledge (TEK) and Local Ecological Knowledge (LEK). Understanding the difference between them helps prevent important distinctions from being blurred.
Traditional Ecological Knowledge (TEK)
Traditional Ecological Knowledge (TEK) refers to cumulative, adaptive, and place-based environmental knowledge developed through long-term relationships between Indigenous communities and their ecosystems. It includes ecological observations, land and resource management practices, ethical principles, and cosmological understandings passed down across generations.
TEK is grounded in sustained engagement with the natural world—through close observation of seasonal cycles, species behavior, hydrology, soils, and landscape change. This knowledge evolves collectively, through lived practice and ongoing adaptation, rather than through isolated experimentation.
What distinguishes TEK is that knowledge and responsibility are inseparable. Ecological understanding is embedded within cultural, spiritual, and ceremonial systems, and guided by ethical commitments to reciprocity, care, and restraint. For this reason, TEK is not simply environmental information—it is a governed knowledge system that includes protocols for use, transmission, and accountability.
This is also why TEK has informed applied fields such as conservation, climate adaptation, biodiversity governance, fisheries, forestry, and co-management initiatives, while remaining grounded in Indigenous sovereignty and relational ethics.
Local Ecological Knowledge (LEK)
Local Ecological Knowledge (LEK), by contrast, refers to place-based environmental knowledge developed through lived experience by both Indigenous and non-Indigenous communities. Like TEK, it can offer valuable insights into local ecosystems, species behavior, and environmental change.
The key difference lies in scope and grounding. LEK generally does not carry the broader cosmological, spiritual, political, or governance dimensions that are integral to TEK. While it can inform local practice, it does not necessarily involve intergenerational responsibility, ceremonial relationships, or collective systems of authority.
Recognizing this distinction matters. When TEK is collapsed into generalized “local knowledge,” the ethical and sovereign dimensions of Indigenous knowledge are often lost, making it easier for these systems to be extracted or instrumentalized without accountability.
Conclusion
Clarifying how terms like Indigenous, Indigenous Knowledges, TEK, and LEK are used reveals how language actively shapes engagement. These are not neutral labels: they influence whose knowledge is recognized, how it is interpreted, and under what conditions it is taken up or dismissed. When distinctions are blurred, entire systems of meaning, governance, and responsibility risk being flattened or misrepresented.
Conceptual clarity, as framed here, is not about fixing definitions or reducing complexity. It is about acknowledging that Indigenous knowledge systems are situated, relational, and governed—rooted in specific peoples, places, and ethical frameworks. Treating them as interchangeable categories or technical inputs strips them of context and opens the door to extractive forms of recognition that reproduce existing power imbalances.
By making these distinctions visible, this blog lays the groundwork for more responsible engagement. Attention to language becomes a way of honoring epistemic integrity and resisting inherited research habits that separate knowledge from land, community, and obligation. Only from this grounding can future conversations—about practice, medicine, or transformation—move forward without repeating the same patterns under different names.
