Concept Definition Deliverable(s)
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)

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.

beneficiary

Europe and Central Asia assessment
beneficiary pays principle

The beneficiary pay principle aims to compensate providers for costs involved in production of beneficial environmental goods and services.

Land degradation and restoration assessment
benefit

Something that promotes or enhances well-being; an advantage. Benefits may be monetary, health, or environmental or any combination thereof.

Pollination assessment
benefit sharing

Distribution of benefits between stakeholders.

Asia-Pacific assessment, Americas assessment, Global assessment (1st work programme), Land degradation and restoration assessment, Sustainable use assessment, Europe and Central Asia assessment
benefit

Advantage that contribute to well-being from the fulfilment of needs and wants. In the context of nature's contributions to people.

Europe and Central Asia assessment
benefit

Advantage that contributes to well-being from the fulfilment of needs and wants.

Asia-Pacific assessment
benefit

Advantage that contributes to wellbeing from the fulfilment of needs and wants. In the context of nature's contributions to people (see Nature's contributions to people), a benefit is a positive contribution. (There may also be negative contributions, dis-benefits, or costs, from Nature, such as diseases).

Americas assessment, Global assessment (1st work programme), Land degradation and restoration assessment
benthic

Occurring at the bottom of a body of water; related to benthos.

Europe and Central Asia assessment, Sustainable use assessment, Americas assessment, Asia-Pacific assessment
benthos

A group of organisms, including invertebrates, that live in or on the bottom in aquatic habitats.

Europe and Central Asia assessment
benthos

A group of organisms, other invertebrates, that live in or on the bottom in aquatic habitats.

Americas assessment, Asia-Pacific assessment
bequest value

The satisfaction of preserving the option of future generations to enjoy nature’s benefits.

Scenarios and models assessment
best practice

A method or technique that consistently shows results superior to those achieved by other means, and that can be used as a benchmark. Best practices evolve agro-ecosystem properties (soil health, water storage, pest and disease resistance) by incorporating benefits of with improvements. Best practices can be used to maintain quality as an alternative to mandatory legislated standards and may be based on self-assessment or benchmarking.

Pollination assessment
biennial

See annual.

bio-prospectors

Exploration of biodiversity for commercially, scientifically, or culturally valuable genetic and biochemical resources.

Sustainable use assessment
bio-technical stabilization

A method for mitigating land degradation using mechanical (structures) and biological elements to prevent severe erosion.

Land degradation and restoration assessment
bioaccumulation

Some contaminants that enter biological systems are preferentially stored (usually in fat tissue) in organisms resulting in an accumulation over time. This process is called bioaccumulation.

Americas assessment
bioaccumulation

The accumulation of environmental pollutants such as isotopes of elements, inorganic and organic compounds in organisms or the environment.

Land degradation and restoration assessment
biocapacity

The definition that follows is for the purpose of this assessment only: Biocapacity has a variety of definitions, but is defined by the Global Footprint Network the as the ecosystems' capacity to produce biological materials used by people and to absorb waste material generated by humans, under current management schemes and extraction technologies. The ‘biocapacity' indicator used in this report is based on the Global Footprint Network unless otherwise specified.

Asia-Pacific assessment
biocapacity

The ecosystem's capacity to produce biological materials used by people and to absorb waste material generated by humans, under current management schemes and extraction technologies. The biocapacity indicator used in the present report is based on the Global Footprint Network, unless otherwise specified.

The capacity of a country, a region, or the world, to produce useful biological materials for its human population and to absorb waste materials.

Europe and Central Asia assessment, Land degradation and restoration assessment
biocentric perspectives

Recognizing the importance of non- human life.
