Traditional ecological knowledge (TEK) is a cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationship of living beings (including humans) with one another and with their environment.
The application of TEK in the field of ecological management and science is still controversial, as methods of acquiring and collecting knowledge—although often including forms of

scientific ecological knowledge. Non-tribal government agencies, such as the
U.S. EPA, have established integration programs with some tribal governments in order to incorporate TEK in environmental plans and climate change tracking. In contrast to the
universality towards which contemporary academic pursuits often aim, TEK is not necessarily a universal concept among various societies, instead referring to a system of knowledge traditions or practices that are heavily dependent on "place".

History
"The earliest systematic studies of TEK were done by anthropologists. Ecological knowledge was studied through the lens of
ethnoecology (an approach that focuses on the conceptions of ecological relationships held by a people or a culture)..." in understanding how systems of knowledge were developed by a given culture.
Harold Colyer Conklin, an American anthropologist took the lead in documenting indigenous ways of understanding the natural world. Conklin and others documented how traditional peoples, such as Philippine horticulturists, had detailed knowledge about the plants and animals where they resided. Direct involvement in gathering, fashioning products from, and using local plants and animals created a scheme in which the biological world and the cultural world were tightly intertwined. The field of TEK encompasses a broad range of questions related to

The report points out that the successes of the 20th century (decreases in infant mortality, increases in life expectancy, increases in literacy, and global food production) have given rise to trends that have caused environmental degradation "in an ever more polluted world among ever decreasing resources." The report declared that tribal and indigenous peoples had lifestyles that could provide modern societies with lessons for management of resources in complex forest, mountain, and dryland ecosystems.
Fulvio Mazzocchi of the
Italian National Research Council's Institute of Atmospheric Pollution outlines the characteristics of TEK as follows:
Some anthropologists, such as M. Petriello and A. Stronza, warn that presenting TEK as an "indigenous" construct will cause the privileging of certain types of TEK over others and restricting which groups are thought to possess TEK results in reduced understanding of and collaboration with groups such as
campesinos who while not often classified as "indigenous" nevertheless possess TEK. The term TEK has been criticised as a form of intellectual appropriation that modifies traditional/indigenous knowledges to better fit a conventional Western modern science framework.
Aspects of traditional ecological knowledge
Nicholas Houde, in an article published in ''
Ecology and Society'', identifies six facets of traditional ecological knowledge: factual observations, management systems, past and current uses, ethics and values, culture and identity, and cosmology. These aspects emphasize how "cooperative management
anbetter identify areas of difference and convergence when attempting to bring two ways of thinking and knowing together."
Factual observations
The first aspect of traditional ecological knowledge incorporates the factual, specific observations generated by recognition, naming, and classification of discrete components of the environment. This type of "empirical knowledge consists of a set of generalized observations conducted over a long period of time and reinforced by accounts of other TEK holders."
Management systems
The second facet refers to the ethical and sustainable use of resources in regards to management systems. More specifically, issues such as dealing with pest management, resource conversion, multiple cropping patterns, and methods for estimating the state of resources can be thought of as part of such management systems. How resource management can adapt to local environments is another crucial aspect of such considerations.
Past and current uses
The third facet refers to the time dimension of TEK, focusing on past and current uses of the environment transmitted through oral history, such as land use, settlement, occupancy, and harvest levels. Oral history is used to transmit cultural heritage generation to generation about such topics as medicinal plants and the existence of historical sites, and contributes to a sense of family and community.
Ethics and values
The fourth facet refers to value statements and connections between the belief system and the organization of facts. In regards to TEK it refers to
environmental ethics
In environmental philosophy, environmental ethics is an established field of practical philosophy "which reconstructs the essential types of argumentation that can be made for protecting natural entities and the sustainable use of natural resourc ...
that keeps exploitative abilities in check. This facet also refers to the expression of values concerning the relationship with the habitats of species and their surrounding environment - the human-relationship environment.
Culture and identity

The fifth facet refers to the role of language and images of the past giving life to culture. This facet reflects the stories, values, and social relations that reside in places as contributing to the survival, reproduction, and evolution of aboriginal cultures, and identities while stressing "the restorative benefits of cultural landscapes as places for renewal."
Cosmology
The sixth facet is a culturally based cosmology that is the foundation of the other aspects. This can vary greatly from one culture to the next. The term 'cosmology' relates to the assumptions and beliefs cultures have about how things work, explains the way in which things are connected, and gives principles that regulate human–animal relations and the role of humans in the world.

is the practice of restoring a degraded ecosystem through human intervention. There are many links between ecological restoration and ecosystem management practices involving TEK. Due to the aforementioned unequal power between indigenous and non-indigenous peoples, equitable partnerships formed in theses contexts can help mitigate extant social injustices, as in the case when Indigenous Peoples lead ecological restoration projects.

Climate change
Climate change is affecting indigenous people in different ways depending on the geographic region which require different adaption and mitigation actions. For example, to immediately deal with these conditions, the indigenous people adjust when they harvest and what they harvest and also adjust their resource use. Climate change can change the accuracy of the information of TEK. The indigenous people have relied on indicators in nature to plan activities and even for short- term weather predictions. As a result of ever more increasingly unusual conditions, entire indigenous cultures have been disrupted and displaced. As a result, there is a loss of the cultural ties to the lands they once resided on and there is also a loss of the traditional ecological knowledge they had with the land there. Climate change adaptations have the potential to harm indigenous rights. The US EPA promised to take traditional ecological knowledge into consideration in planning adaptations to climate change.
The rising temperature poses a threat for ecosystems including the locations where plants grow, the times that insects emerge throughout the year, and changes to the seasonal habitats of animals. For many harvesting seasons, indigenous people have shifted their activity months earlier due to impacts from climate change, adaptations that becomes more important in the face of a rapidly changing climate. Climate change can therefore affect the availability and quality of environmental resources for indigenous people. For example, as sea ice levels decrease, Alaska Native peoples have experienced changes in their daily lives. Thawing permafrost has damaged buildings and roadways while clean water resources dwindle. Fishing, transportation, social and economic aspects of their lives are destabilized. Additionally, as the temperature gets hotter, disasters such as uncontrolled wild fires become more likely. One Indigenous nation in Australia was recently given back land and they reinstated their traditional practice of controlled burning. This was documented to increase the area's biodiversity and decrease the severity of the wildfires. Traditional ecological knowledge can help provide information about

Examples
Instances where TEK was recognized in the literature are included below.
Karuk and Yurok Burning
Environmental sociologist Kirsten Vinyeta and tribal climate change researcher Kathy Lynn reported on the
Karuk Tribe of California: "Traditional burning practices have been critical to the Karuk since time immemorial. For the Tribe, fire serves as a critical land management tool as well as a spiritual practice." Environmental studies professor Tony Marks-Block, ecological researcher Frank K. Lake, and tropical forester Lisa M. Curran explained how the Karuk and the
Yurok Tribes organized
controlled burns and fuel reduction treatments in their ancestral territories to reduce wildfire risk and "restore ecocultural resources depleted from decades of fire exclusion". Professor of sociology Kari Norgaard and Karuk tribe member William Tripp recommend "this process... be replicated and expanded to other communities throughout the western Klamath Mountains and beyond" to promote the positive outcomes seen as a result of the custodial burns of these tribes.

Agroforestry in northeast India
In India, indigenous knowledge relating to agroforestry has been passed down for generations. One paper suggests mitigating the negative impacts of colonial-era and more recent corporate land management practices could be achieved through a revival of traditional farming methods.
One traditional farming practice is

, also known as shifting cultivation or "slash and burn". This is a common practice in northeastern India, where sections of land are regularly burned and returned to after the soil's fertility is restored. The practice of jhum heightens carbon storage and biodiversity. Jhum paired with certain plant-based pesticides was demonstrated to create an agroforestry structure that could function without dependence on industrial fertilizers and pesticides.
