Concept Definition Deliverable(s)
forest

A minimum area of land of 0.05-1.0 hectares with tree crown cover (or equivalent stocking level) of more than 10-30 per cent with trees with the potential to reach a minimum height of 2-5 metres at maturity in situ. A forest may consist either of closed forest formations where trees of various stories and undergrowth cover a high proportion of the ground or open forest.

formal institution

Include law and policies e.g. regulations and directives, and fiscal, agricultural or planning policies, to name just a few examples. These are typically based on legal instruments, treaties and customary laws. Informal institutions in turn include social norms and rules, such as those related to collective action.

free, prior and informed consent

Free implies that Indigenous Peoples and Local Communities are not pressured, intimidated, manipulated or unduly influenced and that their consent is given, without coercion; prior implies seeking consent or approval sufficiently in advance of any authorization to access traditional knowledge respecting the customary decision-making processes in accordance with national legislation and time requirements of Indigenous Peoples and Local Communities; informed implies that information is provided that covers relevant aspects, such as: the intended purpose of the access; its duration and scope; a preliminary assessment of the likely economic, social, cultural and environmental impacts, including potential risks; personnel likely to be involved in the execution of the access; procedures the access may entail and benefit-sharing arrangements; consent or approval is the agreement of the Indigenous Peoples and Local Communities who are holders of traditional knowledge or the competent authorities of those Indigenous Peoples and Local Communities, as appropriate, to grant access to their traditional knowledge to a potential user and includes the right not to grant consent or approval.

Global assessment (1st work programme)
functional trait

A feature of an organism, which has demonstrable links to the organism's function (Lavorel et al. 1997). As such, a functional trait determines the organism's response to pressures (Response trait), and/or its effects on ecosystem processes orservices(Effect trait).Functional traits are considered as reflecting adaptations to variation in the physical and biotic environment and trade-offs (ecophysiological and/or evolutionary) among different functions within an organism. In plants, functional traits include morphological, ecophysiological, biochemical and regeneration traits, including demographic traits(at population level). In animals, these traits are combined with lifehistory and behavioural traits (e.g. guilds, organisms that use similar resources/ habitats).

Asia-Pacific assessment
functional trait

Any feature of an organism, expressed in the phenotype and measurable at the individual level, which has demonstrable links to the organism's function. As such, a functional trait determines the organism's response to external abiotic or biotic factors (response trait), and/or its effects on ecosystem properties or benefits or detriments derived from such properties (effect trait). In plants, functional traits include morphological, ecophysiological, biochemical and regeneration traits. In animals, these traits include e.g. body size, litter size, age of sexual maturity, nesting habitat, time of activity.

indigenous and local knowledge

The knowledge, practices and innovations embedded in the relationships of Indigenous Peoples and Local Communities to nature. ILK is situated in a place and social context, but at the same time open and hybrid, continuously evolving through the combination of written, oral, tacit, practical, and scientific knowledge attained from various sources, and validated by experimentation and in practice of direct interaction with nature. See chapter 1 (section 1.3.2.1) and chapter 2.2 (section 2.2.2) for a discussion on the differences between ‘indigenous knowledge’ and ‘local knowledge’.

indigenous communities

Human communities that are self- identified as indigenous; descent from the occupants of a territory prior to an act of conquest; possession of a common history, language, and culture regulated by customary laws that are distinct from national cultures; possession of a common land; exclusion or marginalization from political decision-making; and claims for collective and sovereign rights that are unrecognized by the dominating and governing group(s) of the state. Indigenous Peoples are often thought of as the primary stewards of the planet's biological resources. Their ways of life and cosmovisions (value systems that interpret and relate the world, life, things and time) have contributed to the protection of the natural environment on which they depend.

indigenous communities

Social groups of indigenous peoples.

Asia-Pacific assessment
Indigenous People

Are the holders of unique languages, knowledge systems and beliefs and possess invaluable knowledge of practices for the sustainable management of natural resources based on their traditional values, visions, needs and priorities. Are inheritors and practitioners of unique cultures and ways of relating to people and the environments. Indigenous people have retained social, cultural, economic and political characteristics that are distinct from those of the dominant societies in which they live.

Africa assessment
Indigenous Peoples and local communities

Indigenous peoples and local communities (IPLCs) are, typically, ethnic groups who are descended from and identify with the original inhabitants of a given region, in contrast to groups that have settled, occupied or colonized the area more recently.

Values assessment
Indigenous Peoples and local communities

Typically, ethnic groups who are descended from and identify with the original inhabitants of a given region, in contrast to groups that have settled, occupied or colonized the area more recently. IPBES does not intend to create or develop new definitions of what constitutes indigenous peoples and local communities.

Land degradation and restoration assessment
Indigenous Peoples and local communities

The term “Indigenous Peoples and local communities” and its acronym “IPLC” are widely used by international organizations and conventions to refer to individuals and groups who self-identify as indigenous or as members of distinct local communities. We adopt this terminology in this assessment, with particular emphasis on those who “maintain an inter-generational historical connection to place and nature through livelihoods, cultural identity, languages, worldviews, institutions, and ecological knowledge”.

Sustainable use assessment
Indigenous Peoples and local communities

Ethnic groups who are descended from and identify with the original inhabitants of a given region, in contrast to groups that have settled, occupied or colonized the area more recently. IPBES does not intend to create or develop new definitions of what constitutes indigenous peoples and local communities.

Americas assessment
Indigenous Peoples and local communities

Indigenous people are also known as first peoples, aboriginal peoples, native peoples, or autochthonous peoples, are ethnic groups who are descended from and identify with the original inhabitants of a given region, in contrast to groups that have settled, occupied or colonized the area more recently. The distinctive groups, usually maintaining traditions or other aspects of an early culture that is associated with a given region, are protected in international or national legislation as having a set of specific rights based on their linguistic and historical ties to a particular territory, prior to later settlement, development, and or occupation of a region. Local community is a self-identified human group that relates to a life environment in collective ways that participate to define a shared territory and culture. The members of a local community have frequent chances of direct (possibly face-to-face) encounters and possess some common history, traditions, institutions, language, values and life plans. A local community can be long-standing (‘traditional') or relatively new, include a single or multiple ethnic identities and be permanently settled or mobile. A local community should have a form of political identity that enables it to exercise its rights and responsibilities with respect to its territory and neighbors.
