Concept Definition Deliverable(s)
fragmentation

The process or state of breaking or being broken into fragments. Often used in reference to habitats.

Asia-Pacific assessment
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), Sustainable use assessment
functional diversity

The range, actual values, relative abundance and distribution of functional trait attributes in a given community.

Europe and Central Asia assessment
functional diversity

Value, range and relative abundance of functional traits in a given ecosystem.

Global assessment (1st work programme), Land degradation and restoration assessment
functional diversity

The range, actual values and relative abundance of functional trait attributes in a given community.

functional extinction

See 'Exctinction'.

Global assessment (1st work programme)
functional group

A collection of organisms with similar suites of co-occurring functional attributes. Groups are traditionally associated with similar responses to external factors and/ or effects on ecosystem processes. A functional group is often referred to as ‘guild.

Sustainable use assessment, Global assessment (1st work programme)
functional redundancy

The occurrence in the same ecosystem of species filling similar roles, which results in a sort of insurance in the ecosystem, with one species able to replace a similar species from the same functional niche.

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.

Europe and Central Asia assessment, Global assessment (1st work programme)
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 (Lavorel et al. 1997; Violle et al. 2007). 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.

Americas assessment, Pollination assessment, Global assessment (1st work programme)
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.

Global assessment (1st work programme)
fungicide

A substance that kills or inhibits the growth and development of fungi. Fungicides may be synthetic chemicals, natural chemicals, or biological agents.

Pollination assessment
qualitative storyline

Articulation of narratives describing plausible futures based on or relating to measures of the quality of key compnents rather than their quantity (c.f. Quantitative approaches).

Asia-Pacific assessment
quality of life

Within the context of the IPBES Conceptual Framework - good quality of life refers to the achievement of a fulfilled life, a notion which may vary significantly across societies and cultures. There is a common understanding that quality of life is composed of both shared common aspects across cultures (food security) and contextual aspects (e.g. self-determination), which can be assessed objectively (e.g. caloric intake) or subjectively (e.g. life satisfaction) applying quantitative and qualitative indicators. Good quality of life is generally portrayed through material conditions (e.g. level of food availability) as well as through individual aspirations (e.g. personal; professional; spiritual) and capabilities (e.g. education) for people to live in accordance to what they themselves consider to be “a good life”, which can differ across cultures, contexts and individuals. The role of nature in achieving a good quality of life is complex and heterogeneous, and depends on the social-ecological context, and on the way people portray themselves in relation to nature.

Values assessment
quantitative model

Statistical or other analytical descriptions of processes defined by quantities or metrics.
