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.

non-anthropogenic

A non-anthropocentric value is a value centred on something other than human beings. These values can be non- instrumental (e.g. a value ascribed to the existence of specific species for their own sake) or instrumental to non-human ends (e.g. the instrumental value a habitat has for the existence of a specific species).

non-extractive practices

Non-extractive practices are defined as practices based on the observation of wild species in a way that does not involve the harvest or removal of any part of the organism. The observation can imply some interaction with the wild species, such as the activities of wildlife and whale watching or no interaction with the wild species, such as remote photography.

non-indigenous or non-native or alien species

See invasive alien species.

non-instrumental value_1

See values.

non-instrumental value_2

The value attributed to something as an end in itself, regardless of its utility for other ends.

non-lethal harvest

Non-lethal harvest is defined as the temporary or permanent capture of live animals from their habitat without mortality, such as for the aquarium trade, pet trade or zoos, tag and release activities. Non-lethal harvest of animals also includes the parts or products of animals that do not lead to the mortality of the host, such as vicuna fiber, swift nests or wild honey.

non-linear

Not arranged in a straight line, not sequential or straightforward.

non-monetary valuation

The value attributable to an item or a service without relation to any acceptable cash price and for which a fixed or determinable amount of currency is absent (e.g. many ecosystem services, interpersonal good-will, health, etc.).

non-timber forest products

Non-timber forest products (NTFPs) are useful substances, materials and/or commodities obtained from forests which do not require harvesting (logging) trees. They include game animals, fur-bearers, nuts, seeds, berries, mushrooms, oils, foliage, pollarding, medicinal plants, peat, mast, fuelwood, fish, spices and forage.

non-timber forest products (ntfps)

Any biological resources found in forests other than timber, including fuel wood and small wood, nuts, seeds, oils, foliage, game animals, berries, medicinal plants, fish, spices, barks, and mushrooms, among others (Prasad, 1993).

non-timber resource

A multitude of natural products (excluding timber) selectively harvested from the terrestrial environment for subsistence and commercial purposes.

normative scenarios

see target- seeking scenarios.

norms

Norms are rules about what is accepted behaviour. They are supporting underlying values as defined by a society. They are therefore ‘ought to’ statements defining what one may or may not do. Examples are rules about care for nature and what is just treatment of others.

nox

A generic term for the nitrogen oxides most relevant for air pollution (NO and NO2) (Omidvarborna et al., 2015).

nutrient availability

Nutrients that can be extracted by plant roots, generally from the soil (Silver, 1994).

nutrient cycle

A repeated pathway of a particular nutrient or element from the environment through one or more organisms and back to the environment. Examples include the carbon cycle, the nitrogen cycle and the phosphorus cycle.

nutrient cycling

The processes by which elements are extracted from their mineral, aquatic, or atmospheric sources or recycled from their organic forms, converting them to the ionic form in which biotic uptake occurs and ultimately returning them to the atmosphere, water, or soil.

observing

Observing is defined as a non-extractive practice that is based on the observation of wild species. The observation can imply some interaction with the wild species, such as the activities of wildlife tourism and whale watching or no interaction with the wild species, such as photography.

ocean acidification_1

See acidification.

oceanic gyre

Large system of rotating ocean currents. There are five major gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre (NOAA, 2018c).

oceanic oxygen minimum zones (omzs)

Oxygen-deficient layers in the ocean water column. OMZs correspond to subsurface oceanic zones reaching ultra-low values of O2 concentration (Paulmier & Ruiz-Pino, 2008).

oil spill

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.

old-growth forest

From an ecological point of view, old-growth forests are a stage of forest development characterized by large/old trees and structural complexity including live and dead trees, and vertical and horizontal heterogeneity (including a multi-layered canopy). The structural diversity of old growth forests often supports distinctive/specialist biodiversity; large/old trees are keystone components of the ecosystem (Lindenmayer et al., 2012). In addition, the long-period of forest development without stand replacement disturbance allows many poor-dispersing species to accumulate (IUFRO, 2018). Other definitions can be found based on economic and social perspectives (Hilbert & Wienscczyk, 2007).

oligotrophic

Nutrient-poor environment (IUCN, 2012a).

oligotrophic_2

Nutrient-poor environment.

one health

The One Health Initiative is a movement to forge co-equal, all inclusive collaborations between physicians, osteopathic physicians, veterinarians, dentists, nurses and other scientific-health and environmentally related disciplines.

ontology_1

The philosophical study of the nature of being, becoming, existence, or reality, as well as the basic categories of being and their relations.

ontology_2

The study or concern about what kinds of things exist - what entities there are in the universe. It is a branch of metaphysics,.

open ocean pelagic systems (oops)

Marine ecosystems in the light-flooded (euphotic) zone.

opportunity costs_1

The added cost of using resources (as for production or speculative investment) that is the difference between the actual value resulting from such use and that of an alternative (such as another use of the same resources or an investment of equal risk but greater return).

opportunity costs_2

The foregone benefits of carrying out one activity in favor of another, or giving up their initial preferred land-use plan.

option value

The potential ability to use some of nature’s benefits in the future, although they are not currently used, or the likelihood for their future use is low. It represents the willingness to preserve an option for the future enjoyment of nature’s benefits.

organic agriculture_1

Any system that emphasizes the use of techniques such as crop rotation, compost or manure application, and biological pest control in preference to synthetic inputs. Most certified organic farming schemes prohibit all genetically modified organisms and almost all synthetic inputs. Its origins are in a holistic management system that avoids off-farm inputs, but some organic agriculture now uses relatively high levels of off-farm inputs.

organic agriculture_2

Any system that emphasises the use of techniques such as crop rotation, compost or manure application, and biological pest control in preference to synthetic inputs. Most certified organic farming schemes prohibit all genetically modified organisms and almost all synthetic inputs. Its origins are in a holistic management system that avoids off-farm inputs, but some organic agriculture now uses relatively high levels of off-farm inputs.

organic farming

Crop and livestock production using natural sources of nutrients (such as compost, crop residues, and manure) and natural methods of crop and weed control, instead of using synthetic or inorganic agrochemicals. Genetically modified organisms are not usually part of organic agriculture. It is also sometimes called low- input farming, but may involve high inputs of labour and be intensive in its practice.

other effective area- based conservation measures (oecm)

A geographically defined area other than a protected area, which is governed and managed in ways that achieve positive and sustained long- term outcomes for the in situ conservation of biodiversity (CBD, 2018a).
