IPBES core glossary

The IPBES core glossary provides a standard definition for important terms of broad applicability to IPBES outputs. This core glossary does not replace the assessment-specific glossaries, but is complementary to them. It was developed by a glossary committee established for this purpose.

alien species

See invasive alien species.

alien species_1

A species, subspecies, or lower taxon occurring outside of its natural range (past or present) and dispersal potential (i.e. outside the range it occupies naturally or could not occupy without direct or indirect introduction or care by humans) and includes any part, gametes or propagule of such species that might survive and subsequently reproduce. Also known as non-native, non-indigenous, foreign, or exotic species.

alien species_ias

a species whose presence in a region is attributable to human actions, intentional or unintentional, that enable them to overcome biogeographical barriers (Richardson et al., 2010; Figure 1.1). This includes species, subspecies or lower taxon, and any part (gametes, seeds, eggs, or propagules) of such species that might survive and subsequently reproduce

alliance for zero extinction sites

Refer to sites containing 95% or more of the remaining population of one or more species listed as endangered or critically endangered on the IUCN Red List of Threatened Species.

alluvial soil

Soils deposited by water.

alpha diversity

The diversity of species within a particular area or ecosystem, expressed by the number of species (species richness) present there.

alternative futures

Plausible future pathways either arising from or forming scenario assessments, often presented as narratives that explore or articulate possibilities.

alternative trajectories

Variable pathways or routes leading to plausible Alternative Futures.

ameliorative policy arrangements

Policy combinations that act to improve condistions or situations.

amorphous

Without a clearly defined shape or form.

anaerobic

Descriptive of a condition in which molecular oxygen is not available.

animism_1

The attribution of a living soul to living beings, inanimate objects, and natural phenomena.

animism_2

The attribution of a soul to plants, inanimate objects, and natural phenomena.

annual_1

In Botany, refers to plants that grow from seed to maturity, reproduction and death in one year. Related terms are biennial (plants that take two years to complete their life cycles), and perennial (plants that take several or many years to complete their life cycles).

annual_2

adj. Referring to events that occur once each year. Botanical meaning refers to plants that grow from seed to maturity, reproduction and death in one year. Related terms are biennial (plants that take two years to complete their life cycles), and perennial (plants that take several to many years to complete their life cycles).

annual_3

In botany, refers to plants that grow from seed to maturity, reproduction and death in one year. Related terms are biennial (plants that take two years to complete their life cycles), and perennial (plants that take several many years to complete their life cycles).

anoxic

Depleted of dissolved oxygen.

anoxic event

Extreme coastal hypoxic conditions (dissolved oxygen <0.5mL per liter), leading to dead zones with mass mortality of benthic fauna.

anthrome_1

A shortened form for 'anthropogenic biome', also known as 'human biome'. Describes the contemporary, human-altered form of biomes. Transformation to an anthrome occurs where people capture one or more nature's contributions to people into anthropogenic pa.

anthrome_2

Neologism for Anthropogenic biome, i.e. an ecosystem produced by humans.

anthropocene

A proposed term for the present time interval, which recognizes humanity’s profound imprint on and role in the functioning of the Earth system. Since it was first proposed in 2000, the term has evolved in breadth and diversely, now ranging from a proposed definition of a new geological epoch, a widely-used metaphor for global change, a novel analytical framework, a meme about the relationship of society to nature, and the framing for new and contested cultural narratives. Different starting periods have been proposed for the geological definition of the Anthropocene, including early agriculture and domestication, colonial species exchange, the onset of the industrial revolution, nuclear bomb deployment in 1945, and the post-WWII period characterized by the great acceleration of global changes and the spread of techno-fossils. A proposal to formalize the ‘Anthropocene’ as a defined geological unit within the Geological Time Scale remains under discussion by the ‘Anthropocene’ Working Group for consideration by the International Commission on Stratigraphy.

anthropocene_2

A proposed term for the present time interval, which recognizes humanity’s profound imprint on and role in the functioning of the Earth system. Since it was first proposed in 2000, the term has evolved in breadth and diversity, now ranging from a proposed definition of a new geological epoch, a widely-used metaphor for global change, a novel analytical framework, a meme about the relationship of society to nature, and the framing for new and contested cultural narratives.

A proposal to formalize the ‘Anthropocene’ as a defined geological unit within the Geological Time Scale remains under discussion by the ‘Anthropocene’ Working Group for consideration by the International Commission on Stratigraphy.

anthropocentric

Anthropocentric qualifies an action or a perception of a given situation that is interpreted by humans or consider humans as the main focus. Nature's contributions to people are fundamentally anthropocentric.

anthropocentric value_1

Human-centred, the value that something has for human beings and human purposes.

anthropocentric value_2

The value that something has for human beings and human purposes.

anthropocentric value_3

See values.

anthropocentrism (or anthropocentric)

In an anthropocentric view of nature, nature is valued for its benefits to human beings. See Ecocentric.

anthropogenic

Originating from human activity.

anthropogenic assets_1

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.

anthropogenic assets_2

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.

anthropogenic assets_3

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 people.

anthropogenic assets_4

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, work, 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 people.

anthropogenic biome

See 'Anthrome'.

anthropogenic drivers

Drivers associated with human actions/activities that drive changes in biodiversity and ecosystems.

anthropogenic impact

Impacts resulting from human activities.

anthropogenic landscapes

Areas of Earth's terrestrial surface where direct human alteration of ecological patterns and processes is significant, ongoing, and directed toward servicing the needs of human populations for food, shelter and other resources and services including recreation and aesthetic needs.
