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.

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).

Europe and Central Asia assessment, Asia-Pacific assessment, Americas assessment
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)
gathering

Gathering is defined as the removal of terrestrial and aquatic algae, fungi, and plants (other than trees) or parts thereof from their habitats. Gathering may, but often does not, result in the death of the organism. Gathering includes whole plant harvest and removal of above and/or below ground plant parts, as well as the fruiting bodies of macrofungi. It also includes removal of non-woody portions of trees (leaves, propagules, and bark). Where removal of propagules or death of an individual plant occurs (e.g. whole plant and root removal) effects on population sustainability are contingent upon factors including timing, frequency, and intensity of harvest. The harvest of wood and woody parts of trees is encompassed by the definition of logging.

Sustainable use assessment
gender

The term gender refers to the socially-constructed expectations about the characteristics, aptitudes and behaviors associated with being a woman or a man. Gender defines what is feminine and masculine. Gender shapes the social roles that mean and women play and the power relations between them, which can have a profound effect on the use and management of natural resources. Gender is not based on sex or the biological differences between women and men; rather, gender is shaped by culture and social norms. Thus, depending on values, norms, customs and laws, women and men in different parts of the world have adopted different gender roles and relations. Within the same society, gender roles also differ by race/ethnicity, class/caste, religion, ethnicity, age and economic circumstances. Gender and gender roles then affect the economic, political, social, and ecological opportunities and constraints faced by both women and men (Convention on Biological Diversity, 2017). The framing of sex and gender as binaries is in fact a cultural ideology. The empirical reality is that sex is a spectrum, manifesting in a wide array of sex variance. Some people don't neatly fit into the categories of man or woman, or “male” or “female.” For example, some people have a gender that blends elements of being a man or a woman, or a gender that is different than either male or female. Some people don't identify with any gender, or their gender changes over time.

Sustainable use assessment
gene

The basic physical and functional unit of heredity. Genes are made up of DNA, and occupy a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins.

Global assessment (1st work programme), Sustainable use assessment
gene flow

The movement of individuals, and/or the genetic material they carry, from one population to another. Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries.

Global assessment (1st work programme)
general circulation model

Land degradation and restoration assessment
generalist species

A species able to thrive in a wide variety of environmental conditions and that can make use of a variety of different resources (for example, a flower-visiting insect that lives on the floral resources provided by several to many different plants).

Americas assessment, Sustainable use assessment, Europe and Central Asia assessment
genetic composition

The composition in alleles of a population.

Global assessment (1st work programme)
genetic diversity

The variation at the level of individual genes, which provides a mechanism for populations to adapt to their ever-changing environment. The more variation, the better the chance that at least some of the individuals will have an allelic variant that is suited for the new environment, and will produce offspring with the variant that will in turn reproduce and continue the population into subsequent generations.

Sustainable use assessment, Global assessment (1st work programme)

Organism in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination (WHO, 2014). The Cartagena Protocol on Biosafety defines 'living modified organism' as any living organism that possesses a novel combination of genetic material obtained through the use of modern biotechnology.
