Asia-Pacific assessment
assessment report

Assessment reports are published outputs of scientific, technical and socioeconomic issues that take into account different approaches, visions and knowledge systems, including global assessments of biodiversity and ecosystem services with a defined geographical scope, and thematic or methodological assessments based on the standard or the fast-track approach. They are to be composed of two or more sections including a summary for policymakers, an optional technical summary and individual chapters and their executive summaries. Assessments are the major output of IPBES, and they contain syntheses of findings on topics that have been selected by the IPBES Plenary.

Scenarios and models assessment
assisted colonization

Also known as assisted migration or managed relocation, is the act of deliberately moving plants or animals to a different habitat. The destination habitat may have either historically held the species or it may not have hosted the species, but the habitat provides the bioclimatic requirements to support it. Assisted colonization may also supplement an existing population in a site where their numbers are dwindling. This is especially the case where the assisted species are unable to disperse at a rate which keeps pace with the shifting bio-climatic, bio-physical envelope.

Land degradation and restoration assessment
asymmetry (in plant-pollinator networks (q.v.))

The tendency for plant (or pollinator) species with few links to interact with pollinator (or plant) species with many links. In mutualistic networks, such as pollination, nestedness (q.v.) is often asymmetrical with specialists of one group (plants or pollinators) linked to the generalists of the partner group (pollinators or plants).

Land-based climate change mitigation strategy based on maintaining and expanding global forest area, and thus the carbon uptake of forest ecosystems in biomass and soil.

Global assessment (1st work programme)
validation (of models)

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.

Scenarios and models assessment
validation (of 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.

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.

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: 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.

Africa assessment, Land degradation and restoration assessment, Asia-Pacific assessment, Americas assessment, Europe and Central Asia assessment
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.

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.
