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.

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).
