Concept Definition Deliverable(s)
anthropogenic assets

Built-up infrastructure, health facilities, knowledge (including indigenous and local knowledge systems and technical or scientific knowledge, as well as formal and non- formal education), technology (both physical objects and procedures), and financial assets among others.

Pollination assessment, Scenarios and models assessment
anthropogenic assets

Built-up infrastructure, health facilities, or knowledge - including indigenous and local knowledge systems and technical or scientific knowledge - as well as formal and non-formal education, technology (both physical objects and procedures), and financial assets. Anthropogenic assets have been highlighted to emphasize that a good quality of life is achieved by a co-production of benefits between nature and societies.

A concept or construct generated by humans. While it can be argued that all principles and preferences are anthropogenic (human-generated), this does not mean they are all anthropocentric (human-centred).

aquaculture

The farming of aquatic organisms, including fish, molluscs, crustaceans and aquatic plants, involving interventions such as regular stocking, feeding, protection from predators, to enhance production. (In contrast, aquatic organisms which are exploitable by the public as a common property resource, are classed as fisheries, not aquaculture).

aquaculture

The farming of aquatic organisms, including fish, mollusks, crustaceans and aquatic plants, in both inland and coastal areas, and involving some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated.

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).

Pollination assessment
available water capacity

Soil water content useable by plants, based on the effective root penetration depth.

Land degradation and restoration assessment
average genetic variation

The condition of having two different alleles at a gene locus.

Global assessment (1st work programme)
avoided deforestation in conjunction with afforestation and reforestation

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)
backcasting

An analytical technique used to search for target-seeking scenarios that fulfil a predefined goal, or set of goals.

Scenarios and models assessment, Asia-Pacific assessment, Americas assessment
badland

Areas where most soil has been eroded away.

Land degradation and restoration assessment
ballast water

Ballast water is water carried in ships’ ballast tanks to improve stability, balance and trim. It is taken up or discharged when cargo is unloaded or loaded, or when a ship needs extra stability in foul weather. When ships take on ballast water, plants and animals that live in the ocean are also picked up.

Asia-Pacific assessment
bare soil

A land cover class that includes any geographic area dominated by natural abiotic surfaces (bare soil, sand, rocks and so on) where the natural vegetation is absent or almost absent (covers less than 2%).

Land degradation and restoration assessment
basal area

Area occupied by the cross-section of tree trunks and stems at base height (130cm from the ground). It is used to characterize different variables in forest ecology and management, e.g. forest structure, productivity and growth rate.

Global assessment (1st work programme)
baseline

A minimum or starting point with which to compare other information (e.g. for comparisons between past and present or before and after an intervention).

Land degradation and restoration assessment, Sustainable use assessment, Europe and Central Asia assessment
beekeeping

The husbandry of bees, especially honey bees (the genus Apis) but can be applied to other bees (see Managed pollinators).

Pollination assessment
behaviour change

interventions can close or ‘bridge’ the gap between values and behaviour by ensuring that the various conditions are met that together enable people to act consistently with sustainability-aligned values. These conditions can be categorized as providing (i) capability, (ii) opportunity and (iii) motivation to act.

Values assessment
behavioural economics

The study of the influence of emotions and opinions on the decisions people and organizations make in spending and saving. Behavioural economics suggests that human decisions are strongly influenced by context, including the way in which choices are presented to us. Behaviour varies across time and space, and it is subject to cognitive biases, emotions, and social influences. Decisions are the result of less deliberative, linear and controlled processes.

Land degradation and restoration assessment
benchmarking (of models)

The process of systematically comparing sets of model predictions against measured data in order to evaluate model performance.

Scenarios and models assessment
benchmarking (of models)

See models.
