Ethnobiology is the scientific study of the way living things are treated or used by different human cultures. It studies the dynamic relationships between people, biota, and environments, from the distant past to the immediate present.
"People-biota-environment" interactions around the world are documented and studied through time, across cultures, and across disciplines in a search for valid, reliable answers to two 'defining' questions: "How and in what ways do human societies use nature, and how and in what ways do human societies view nature?"
Biologists have been interested in local biological knowledge since the time Europeans started colonising the world, from the 15th century onwards. Paul Sillitoe wrote that:
Europeans not only sought to understand the new regions they intruded into but also were on the look-out for resources that they might profitably exploit, engaging in practices that today we should consider tantamount to biopiracy. Many new crops .. entered into Europe during this period, such as the potato, tomato, pumpkin, maize, and tobacco. (Page 121)
Local biological knowledge, collected and sampled over these early centuries significantly informed the early development of modern biology:
Ethnobiology itself, as a distinctive practice, only emerged during the 20th century as part of the records then being made about other peoples, and other cultures. As a practice, it was nearly always ancillary to other pursuits when documenting others' languages, folklore, and natural resource use. Roy Ellen commented that:
At its earliest and most rudimentary, this comprised listing the names and uses of plants and animals in native non-Western or 'traditional' populations often in the context of salvage ethnography ..[ie] ethno-biology as the descriptive biological knowledge of 'primitive' peoples.
This 'first phase' in the development of ethnobiology as a practice has been described as still having an essentially utilitarian purpose, often focusing on identifying those 'native' plants, animals and technologies of some potential use and value within increasingly dominant western economic systems
Arising out of practices in Phase I (above) came a 'second phase' in the development of 'ethnobiology', with researchers now striving to better document and better understand how other peoples' themselves "conceptualize and categorize" the natural world around them. In Sillitoe's words:
By the mid-20th century .. utilitarian-focussed studies started to give way to more cognitively framed ones, notably studies that centred on elucidating classificatory schemes. (Page 122)
This 'second' phase is marked:
By the turn of the 21st century ethnobiological practices, research, and findings have had a significant impact and influence across a number of fields of biological inquiry including ecology, conservation biology, development studies, and political ecology.
The Society of Ethnobiology advises on its web page:
Ethnobiology is a rapidly growing field of research, gaining professional, student, and public interest .. internationally
Ethnobiology has come out from its place as an ancillary practice in the shadows of other core pursuits, to arise as a whole field of inquiry and research in its own right: taught within many tertiary institutions and educational programs around the world; with its own methods manuals, its own readers, and its own textbooks
All societies make use of the biological world in which they are situated, but there are wide differences in use, informed by perceived need, available technology, and the culture's sense of morality and sustainability. Ethnobiologists investigate what lifeforms are used for what purposes, the particular techniques of use, the reasons for these choices, and symbolic and spiritual implications of them.
Different societies divide the living world up in different ways. Ethnobiologists attempt to record the words used in particular cultures for living things, from the most specific terms (analogous to species names in Linnean biology) to more general terms (such as 'tree' and even more generally 'plant'). They also try to understand the overall structure or hierarchy of the classification system (if there is one; there is ongoing debate as to whether there must always be an implied hierarchy.
Societies invest themselves and their world with meaning partly through their answers to questions like "how did the world happen?", "how and why did people come to be?", "what are proper practices, and why?", and "what realities exist beyond or behind our physical experience?" Understanding these elements of a societies' perspective is important to cultural research in general, and ethnobiologists investigate how a societies' view of the natural world informs and is informed by them.
In order to live effectively in a given place, a people needs to understand the particulars of their environment, and many traditional societies have complex and subtle understandings of the places in which they live. Ethnobiologists seek to share in these understandings, subject to ethical concerns regarding intellectual property and cultural appropriation.
In cross cultural ethnobiology research, two or more communities participate simultaneously. This enables the researcher to compare how a bio-resource is used by different communities.
Main article: Ethnobotany
Ethnobotany investigates the relationship between human societies and plants: how humans use plants – as food, technology, medicine, and in ritual contexts; how they view and understand them; and their symbolic and spiritual role in a culture.
Main article: Ethnozoology
The subfield ethnozoology focuses on the relationship between animals and humans throughout human history. It studies human practices such as hunting, fishing and animal husbandry in space and time, and human perspectives about animals such as their place in the moral and spiritual realms.
Main article: Ethnoecology
Ethnoecology refers to an increasingly dominant 'ethnobiological' research paradigm focused, primarily, on documenting, describing, and understanding how other peoples perceive, manage, and use whole ecosystems.
Studies and writings within ethnobiology draw upon research from fields including archaeology, geography, linguistics, systematics, population biology, ecology, cultural anthropology, ethnography, pharmacology, nutrition, conservation, and sustainable development.
Through much of the history of ethnobiology, its practitioners were primarily from dominant cultures, and the benefit of their work often accrued to the dominant culture, with little control or benefit invested in the indigenous peoples whose practice and knowledge they recorded.
Just as many of those indigenous societies work to assert legitimate control over physical resources such as traditional lands or artistic and ritual objects, many work to assert legitimate control over their intellectual property.
In an age when the potential exists for large profits from the discovery of, for example, new food crops or medicinal plants, modern ethnobiologists must consider intellectual property rights, the need for informed consent, the potential for harm to informants, and their "debt to the societies in which they work".
Furthermore, these questions must be considered not only in light of western industrialized nations' common understanding of ethics and law, but also in light of the ethical and legal standards of the societies from which the ethnobiologist draws information.
