IPBES core glossary

The IPBES core glossary provides a standard definition for important terms of broad applicability to IPBES outputs. This core glossary does not replace the assessment-specific glossaries, but is complementary to them. It was developed by a glossary committee established for this purpose.

units of analysis

The IPBES Units of Analysis result from subdividing the Earth’s surface into units solely for the purposes of analysis. The following have been identified as IPBES units of analysis globally: Terrestrial: Tropical and subtropical dry and humid forests Temperate and boreal forests and woodlands Mediterranean forests, woodlands and scrub Tundra and High Mountain habitats Tropical and subtropical savannas and grasslands Temperate Grasslands Deserts and xeric shrublands Wetlands - peatlands, mires, bogs Urban/Semi-urban Cultivated areas (incl. cropping, intensive livestock farming etc.) Aquatic, including both marine and freshwater: Cryosphere Aquaculture areas Inland surface waters and water bodies/freshwater Shelf ecosystems (neritic and intertidal/littoral zone) Open ocean pelagic systems (euphotic zone) Deep-Sea Coastal areas intensively used for multiple purposes by humans These IPBES terrestrial and aquatic units of analysis serve as a framework for comparison within and across assessments and represent a pragmatic solution. The IPBES terrestrial and aquatic units of analysis are not intended to be prescriptive for other purposes than those of IPBES assessments. They are likely to evolve as the work of IPBES develops.

unpredictability

Something difficult or impossible to foretell or foresee.

unresolved (certainty term (q.v.))

Multiple independent studies exist but conclusions do not agree.

upanishad

Each of a series of Hindu sacred treatises written in Sanskrit c.800-200 BC, expounding the Vedas in predominantly mystical and monistic terms.

upscaling_1

The process of scaling information from local, fine-grained resolution to global, coarse-grained resolution.

upwelling

A process in which deep, cold water rises toward the surface replacing warmer water pushed away by winds. Water that rises to the surface as a result of upwelling is typically colder and rich in nutrients, which “fertilize” surface waters, meaning that these surface waters often have high biological productivity.

urban

adj. Pertaining to the built-up, human- inhabited environment (cities, towns, villages, etc.).

urban ecosystems

Any ecological system located within a city or other densely settled area or, in a broader sense, the greater ecological system that makes up an entire metropolitan area (Pickett, 2018).

urban heat island effect

The term heat island describes built up areas that are hotter than nearby rural areas.

urban metabolism

A method to evaluate the flows of energy and materials within an urban system, which can provide insights into the system's sustainability and the severity of urban problems such as excessive social, community, and household metabolism at scales ranging from global to local.

urbanization

The increase in the proportion of a population living in urban areas; the process by which a large number of people becomes permanently concentrated in relatively small areas, forming cities.

urbanization_1

Increase in the proportion of a population living in urban areas; process by which a large number of people becomes permanently concentrated in relatively small areas, forming cities.

urbanization_1_check

The process by which villages, towns, cities and other built-up areas grow or by which societies become more urban.

use of wild species

The wild species uses are defined through the practices of fishing, gathering, terrestrial animal harvesting, logging, and non-extractive practices. For the purposes of this assessment, the use of wild species have been divided into different categories, which are not mutually exclusive: ceremony and ritual expression, decorative and aesthetic, energy, food and feed, learning and education, materials and construction, medicine and hygiene, recreation and other: companionship.

users

Stakeholders who use the products of an assessment, such as decision-makers.

usufruct right

A legal right accorded to a person or party that confers the temporary right to use and derive income or benefit from someone else’s property.

validation (of models)_1

Typically refers to checking model outputs for consistency with observations. However, since models cannot be validated in the formal sense of the term (i.e. proven to be true), some scientists prefer to use the words benchmarking or evaluation.

validation (of models)_2

See models.

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.

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.

valuation methods

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).

value (as importance)_1

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.

value (as importance)_2

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: 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.

value (as measure)_1

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

value (as preference)_1

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 (as principle)_1

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.

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”

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).

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.

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.

value indicators

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.
