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).

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

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)
habitat

The place or type of site where an organism or population naturally occurs. Also used to mean the environmental attributes required by a particular species or its ecological niche.

Americas assessment, Land degradation and restoration assessment, Africa assessment, Europe and Central Asia assessment, Asia-Pacific assessment, Sustainable use assessment
habitat connectivity

The degree to which the landscape facilitates the movement of organisms (animals, plant reproductive structures, pollen, pollinators, spores, etc.) and other environmentally important resources (e.g. nutrients and moisture) between similar habitats. Connectivity is hampered by fragmentation (q.v.).

Global assessment (1st work programme), Pollination assessment, Land degradation and restoration assessment, Europe and Central Asia assessment, Americas assessment

Land degradation and restoration assessment
habitat fragmentation

A general term describing the set of processes by which habitat loss results in the division of continuous habitats into a greater number of smaller patches of lesser total and isolated from each other by a matrix of dissimilar habitats. Habitat fragmentation may occur through natural processes (e.g. forest and grassland fires, flooding) and through human activities (forestry, agriculture, urbanization).
