Sustainable use assessment
exposure

The state of having no protection from something potential harmful.

Asia-Pacific assessment
extensive forest management

Low or no input in regeneration or site amelioration is practiced in sparsely populated regions with large forest areas, such as boreal forests (Taiga) of Canada and Siberia, and across much of the world´s major tropical forest biomes.

extensive grazing

Extensive grazing is that in which livestock are raised on food that comes mainly from natural grasslands, shrublands, woodlands, wetlands, and deserts. It differs from intensive grazing, where the animal feed comes mainly from artificial, seeded pastures.

Asia-Pacific assessment, Americas assessment
extensive grazing (lands)

A form of grazing in which livestock are raised on food that comes mainly from natural grasslands, shrublands, woodlands, wetlands and deserts. It differs from intensive grazing, where the animal feed comes mainly from artificial, seeded pastures.

Land degradation and restoration assessment
extent (spatial or temporal)

see spatial scale and temporal scale”.

Scenarios and models assessment
externality

A positive or negative consequence (benefits or costs) of an action that affects someone other than the agent undertaking that action and for which the agent is neither compensated nor penalized through the markets.

Land degradation and restoration assessment, Europe and Central Asia assessment, Global assessment (1st work programme), Asia-Pacific assessment, Sustainable use assessment, Americas assessment
externality

an economic concept of uncompensated environmental effects of production and consumption that affect consumer utility and enterprise cost outside the market mechanism

Invasive alien species assessment
extinction

A population, species or more inclusive taxonomic group has gone extinct when all its individuals have died. A species may go extinct locally (population extinction), regionally ( extinction of all populations in a country, continent or ocean) or globally. Populations or species reduced to such low numbers that they are no longer of economic or functional importance may be said to have gone economically or functionally extinct, respectively. Species extinctions are typically not documented immediately: for example, the IUCN Red List categories and criteria require there to be no reasonable doubt that all individuals have died, before a species is formally listed as Extinct (see IUCN Red List).

Sustainable use assessment
extinction debt

The future extinction of species due to events in the past, owing to a time lag between an effect such as habitat destruction or climate change, and the subsequent disappearance of species.

extinction

A population, species or more inclusive taxonomic group has gone extinct when all its individuals have died. A species may go extinct locally (population extinction), regionally (e.g. extinction of all populations in a country, continent or ocean) or glo.

extinction

The evolutionary termination of a species caused by the failure to reproduce and the death of all remaining members of the species; the natural failure to adapt to environmental change.

Americas assessment
extractive practice

Extractive practices are defined as the temporary or permanent removal of organisms, part of them or materials derived from them, and may result in mortality of the individual to be used (hunting or whole plant harvest), but does not necessarily do so (e.g. limited collection of plant propagules or shearing and releasing of vicuna).

Sustainable use assessment
extractives

Hydrocarbons (oil and gas) and minerals.

Americas assessment

keystone species

Species that maintain the organization and diversity of their ecological communities and are thus exceptional, relative to the rest of the community, in their importance. Species that, despite low biomass, exert strong effects on the structure of the communities they inhabit.

Asia-Pacific assessment
kinship-centric principle (non-humans)

animals, plants and spirits, and such approach forms part of an indigenous cultural identity. Maintaining reciprocal and healthy relationships through a continuum with animals, plants and the lands where they reside involve the giving and taking of resources in appropriate ways, at appropriate times. In some cases, animals and plants are seen and treated as equals to humans and shape and reshape human relations with nature. Often, the values embedded in these relationships drive human behaviour and are elicited through certain valuation methods. Appreciation (no disregard) for spiritual entities (e.g. sacred mountains, rivers, among others) residing on ancestral lands, can be an example of a Kinship-central approach (focused on non-humans).

Values assessment
kinship-centric principle (other humans)

Actions of mutual support between humans such as sharing, gender equity, social equity, honesty, humility, modesty. Some of these elements can be revealed as relevant through valuation methods and approaches, as well as by practices associated with them.

Values assessment
knowledge system

Indigenous and local knowledge systems are understood to be dynamic bodies of integrated, holistic, social and ecological understandings, know-hows, practices and beliefs pertaining to the relationship of living beings, including people, with one another and with their environment. Indigenous and local knowledge is grounded in territory, is highly diverse and is continuously evolving through the interaction of experiences, skills, innovations and different types of wisdom expressed in multiple ways (written, oral, visual, tacit, practical and scientific). Such knowledge can provide information, methods, theory and practice for sustainable ecosystem management. Indigenous and local knowledge systems have been, and continue to be, empirically tested, applied, contested and validated through different means in different contexts. Western Academic knowledge systems relate to often explicit knowledge that has been derived from applying formal methods in academic or technical institutions.

Values assessment
knowledge system

A body of propositions that are adhered to, whether formally or informally, and are routinely used to claim truth.

Scenarios and models assessment
knowledge system

A body of propositions that are adhered to, whether formally or informally, and are routinely used to claim truth. They are organized structures and dynamic processes (a) generating and representing content, components, classes, or types of knowledge, that are (b) domain-specific or characterized by domain-relevant features as defined by the user or consumer, (c) reinforced by a set of logical relationships that connect the content of knowledge to its value (utility), (d) enhanced by a set of iterative processes that enable the evolution, revision, adaptation, and advances, and (e) subject to criteria of relevance, reliability, and quality.

Africa assessment
kyoto protocol

An international agreement linked to the United Nations Framework Convention on Climate Change, which commits its Parties by setting internationally binding emission reduction targets.

Asia-Pacific assessment
nagoya protocol

The Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization (ABS) is a supplementary agreement to the 1992 Convention on Biological Diversity. It provides a transparent legal framework for the effective implementation of one of the three objectives of the CBD: the fair and equitable sharing of benefits arising out of the utilization of genetic resources, thereby contributing to the conservation and sustainable use of biodiversity. The Nagoya Protocol aims to create greater legal certainty and transparency for both providers and users of genetic resources by establishing more predictable conditions for access to genetic resources and helping to ensure benefit-sharing when genetic resources leave the country providing the genetic resources. The Nagoya Protocol on ABS was adopted on 29 October 2010 in Nagoya, Japan and entered into force on 12 October 2014.

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

adj. Pertaining to a nation state or people who define themselves as a nation. A nation can be thought of as a large number of people associated with a particular territory and who are sufficiently conscious of their unity to seek or to possess a government peculiarly its own.

Pollination assessment
national biodiversity strategies and action plans

The Convention on Biological Diversity calls on each of its Parties to prepare a National Biodiversity Strategy and Action Plan (Article 6a) that establishes specific activities and targets for achieving the objectives of the Convention. These plans mostly are implemented by a partnership of conservation organizations. Species or habitats which are the subject of NBSAPs are the governments stated priorities for action and therefore raise greater concern where they are threatened. NBSAPs do not carry legal status and listed species and habitat types are not necessarily protected (although some are covered by other legislation) (Hesselink et al., 2007).

native species

taxa that have originated in a given area (their natural range) without human involvement, or that have arrived there without intentional or unintentional intervention of humans, from an area in which they are native (IPBES glossary). This definition excludes products of hybridization involving alien taxa since “human involvement”, in this case, includes the introduction of an alien parent

Invasive alien species assessment

Sustainable use assessment
natural capital

A concept referring to the stock of renewable and non-renewable natural resources ( plants, animals, air, water, soils, minerals) that combine to yield a flow of benefits to people (UNDP, 2016b). Within the IPBES conceptual framework, it is part of the nature category, representing an economic-utilitarian perspective on nature, specifically those aspects of nature that people use (or anticipate to use) as source of Nature's contributions to people.

Sustainable use assessment
natural capital accounts

Sets of linked accounts that contain information about the type and quantities and, where possible, the value of the stocks of natural assets and the flows of services generated by them. The accounts contain two main components: physical accounts - types, quantities and condition of assets; and monetary accounts - application of monetary units of valuation to selected flows of services on an annual basis and associated values of stocks.
