Concept Definition Deliverable(s)
brackish water

Water that has more salinity than fresh water, but not as much as seawater. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers. Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gravity of between 1.005 and 1.010. Thus, brackish covers a range of salinity regimes and is not considered a precisely defined condition.

Asia-Pacific assessment
breadth

refers to change across multiple spheres, with emerging consensus that transformation requires co-evolutionary change across different spheres of society, including personal, economic, political, institutional and technological ones.

Values assessment
bridging organizations

offer a means to improve environmental management outcomes by spanning the science-policy interface to allow for the effective sharing of data, information, and knowledge. Bridging organizations are institutions that use specific mechanisms such as working groups to link and facilitate interactions among individual actors in a management setting.

Invasive alien species assessment
broad values

They refer to life goals, general guiding principles and orientations towards the world that are informed by people’s beliefs and worldviews. Broad values include moral principles, such as justice, belonging, freedom, but also life goals, like enjoyment, health, prosperity. Broad values influence specific values and provide them with a general context and meaning.

Values assessment
buen vivir

Although no universal definition of buen vivir has been attained yet, it has four common constitutive elements: (a) the idea of harmony with nature (including its abiotic components); (b) vindication of the principles and values of marginalized/subordinated peoples; (c) the State as guarantor of the satisfaction of basic needs (such as education, health, food and water), social justice and equality; and (d) democracy. There are also two cross-cutting lines: buen vivir as a critical paradigm of Eurocentric (anthropocentric, capitalist, economistic and universalistic) modernity, and as a new intercultural political project.

Global assessment (1st work programme), Americas assessment
buen vivir

An alternative to economic development-centered approaches, generally defined as forming part of the Andean indigenous cosmology, based on the belief that true wellbeing is only possible as part of a community in a broad sense, including people, nature and the Earth, linked by mutual responsibilities and obligations, and that the wellbeing of the community is above that of the individual.

buffer (ecology)

A natural or anthropogenic feature which separates land uses.

valuation

It is the process of documenting the existence of values, identifying when and where and by whom they are expressed, that in turn allows characterizing values. Valuation of nature can inform decision-making about numerous human-nature relationships; it can support decision processes about alternative projects or policies, inform the design of policy tools and instruments, for conservation and sustainable management of nature or to improve justice. Outside the formal policy space, valuation is also undertaken by academia, the private sector, non-governmental organizations and by indigenous and local communities (IPLC). IPLC undertake valuation not only to make decisions about nature, but also to assess their relationships with nature, to plan collectively, resolve conflicts, defend their territories, and as a means for strengthening and reciprocating their connections with nature.

Values assessment
valuation approach

Valuation approaches are higher level assumptions, ideas or beliefs that underpin methods. They translate key decisions on how a method is to be applied or how the information generated by methods is to be interpreted. For each approach there are often multiple accepted methods that adhere to the basic assumptions and ideas of the given approach. Valuation approaches can also be manifested as “traditions” or widely accepted and expected protocols for undertaking valuation. Valuation traditions are heavily informed and influenced by the cultural context and/or epistemological worldviews.

Values assessment
valuation method

Are the specific techniques and accepted formal procedures that are applied to gather and analyse information from nature and society in order to and understand or make explicit the state of nature and its importance to people a) quantity, quality and status of nature including its spatial and temporal variations; b) the relevance or importance of nature to people and societies; and c) the nature of human-nature and nature-human relations in terms of how people and societies embed and live out their values of nature (as actions, principles, worldviews or philosophies).

Values assessment
value (as importance)

A value can be the importance of something for itself or for others, now or in the future, close by or at a distance. This importance can be considered in three broad classes. 1. The importance that something has subjectively, and may be based on experience. 2. The importance that something has in meeting objective needs. 3. The intrinsic value of something.

This importance can be considered in three broad classes: The importance that something has subjectively, and may be based on experience. The importance that something has in meeting objective needs. The intrinsic value of something.

Africa assessment
value (as measure)

A value can be a measure. In the biophysical sciences, any quantified measure can be seen as a value.

Americas assessment, Europe and Central Asia assessment, Land degradation and restoration assessment, Asia-Pacific assessment, Africa assessment
value (as preference)

A value can be the preference someone has for something or for a particular state of the world. Preference involves the act of making comparisons, either explicitly or implicitly. Preference refers to the importance attributed to one entity relative to another one.

value chains (that link production systems, markets and consumers)

a contact network, which provides opportunities for the transmission of contagious diseases within and between sectors. It follows that these chains (networks) can be understood and taken into account in planning risk management strategies for disease prevention and control” especially in relation with “risky parts of the value chain”

Invasive alien species assessment
value change

Value change refers to the modification of people’s values or of the prioritization of their values in particular contexts. Value change processes occur at different social scales, from large-scale cultural shifts (e.g. intergenerational shifts due to changing demography or changes to shared values) to small-scale personal shifts (e.g. values formation and change over an individual’s lifetime). Individual, social and social-ecological experiences and interactions influence value change; examples include formal and informal education, social practices, group conformation processes, personal experiences and shocks, and social-ecological events (e.g. natural disasters, pandemics).

Values assessment
value expression

Values can be expressed explicitly through language and implicitly through actions like choices, decisions made, everyday practices or rituals. Valuation methods are used to undertake explicit valuation. Methods and approaches to integrate and bridge values, provide knowledge about nature’s values as input to decision-making.

Values assessment
value formation

'Value formation' refers to how values develop in the first place. It can occur in individual-focused processes, trough socially-oriented processes or in social-ecological processes that do not separate humans and nature.

Values assessment
value indicator

Indicators of value are quantitative and qualitative measures of the importance of nature to people. Indicators used to express the value of nature can be biophysical, economic and socio-cultural.

Values assessment
value monism

Derives from a utilitarian perspective on human-nature relationships which privileges some values of nature over others (usually monetary values).

Values assessment
value pluralism

Value pluralism is the idea that there are several values which may be equally correct and fundamental, and yet in conflict with each other. It is the opposite of value monism. More broadly speaking, value pluralism may also refer to different people having different worldviews and hence different values. In addition, these plural values may be incommensurable (i.e. they do not share a single unit of measurement, a single metric, and that there is no objective way of comparing them or weighting them against each other).

Values assessment
value system

Sets of values according to which people, societies and organizations regulate their behaviour.

Scenarios and models assessment
value system

Set of values according to which people, societies and organizations regulate their behaviour. Value systems can be identified in both individuals and social groups.

Africa assessment, Europe and Central Asia assessment, Asia-Pacific assessment, Americas assessment, Land degradation and restoration assessment
value-articulating institution

Methods for valuation of nature and NCPs may be termed value articulating institutions since they are based on a set of rules concerning the valuing process: Participation: who participates; in what capacity; and how. What counts as data and what form it should take (prices, weights, arguments, physical measures etc.). The kind of data handling procedures involved: how data is produced; and how data are compared, weighed or aggregated.

Values assessment
values

Value systems: Set of values according to which people, societies and organizations regulate their behavior. Value systems can be identified in both individuals and social groups (Pascual et al., 2017). Value (as principle): A value can be a principle or core belief underpinning rules and moral judgments. Values as principles vary from one culture to another and also between individuals and groups (IPBES, 2015). Value (as preference): A value can be the preference someone has for something or for a particular state of the world. Preference involves the act of making comparisons, either explicitly or implicitly. Preference refers to the importance attributed to one entity relative to another one (IPBES, 2015). Value (as importance): A value can be the importance of something for itself or for others, now or in the future, close by or at a distance. This importance can be considered in three broad classes. 1. The importance that something has subjectively, and may be based on experience. 2. The importance that something has in meeting objective needs. 3. The intrinsic Please do not cite, quote or circulate 1733 value of something (IPBES, 2015). Value (as measure): A value can be a measure. In the biophysical sciences, any quantified measure can be seen as a value (IPBES, 2015). Non-anthropocentric value: A non-anthropocentric value is a value centered on something other than human beings. These values can be non-instrumental or instrumental to non-human ends (IPBES, 2015). Intrinsic value: This concept refers to inherent value, that is the value something has independent of any human experience or evaluation. Such a value is viewed as an inherent property of the entity and not ascribed or generated by external valuing agents (Pascual et al., 2017). Anthropocentric value: The value that something has for human beings and human purposes (Pascual et al., 2017). Instrumental value: The value attributed to something as a means to achieving a particular end (Pascual et al., 2017). Non-instrumental value: The value attributed to something as an end in itself, regardless of its utility for other ends. Relational value: The values that contribute to desirable relationships, such as those among people or societies, and between people and nature, as in “Living in harmony with nature” (IPBES, 2015). Integrated valuation: The process of collecting, synthesizing, and communicating knowledge about the ways in which people ascribe importance and meaning of Nature’s contributions to people, to facilitate deliberation and agreement for decision making and planning.

Sustainable use assessment
values of nature

The values of nature encompass the different layers of the values typology, including worldviews (and underpinning knowledge systems, languages and cultures), broad values, specific values, indicators and preferences.  In addition to instrumental values, the values of nature include reciprocal values and perspectives of nature where nature and people are not seen as separate, and where intrinsic values are acknowledged on a par with values of nature’s benefits to people.

Values assessment
values of nature

When referring to values of ‘nature’, we expand on the concept proposed by Díaz et al. (2015) by recognizing that individual and group understandings of nature are socially constructed, and that different social groups have different conceptualizations of the relationship between the human and non-human world. For IPBES, nature refers loosely to the non-human living world including the scientific categories of biodiversity, ecosystem structure and functioning, evolution, the biosphere, humankind’s shared evolutionary heritage and biocultural diversity. In addition, IPBES recognises other worldviews, including those from IPLCs, in which people recognize the diverse entities and elements of nature such as rivers, mountains, plants, animal species, existing within the planet denoted by categories like Mother Earth and systems of life . Among many IPLCs, nature is often viewed as inextricably linked to humans, not as a separate entity. By recognizing this wide understanding of the concept ‘nature’, we are then able to recognize the diversity of values that emerges within these different ways of seeing the world.
