An area of land that contains a mosaic of ecosystems, including human-dominated ecosystems.

Americas assessment, Sustainable use assessment, Europe and Central Asia assessment
large scale land acquisition

The control (whether through ownership, lease, concession, contracts, quotas, or general power) of larger than locally-typical amounts of land by any persons or entities (public or private, foreign or domestic) via any means (‘legal’ or ‘illegal’) for purposes of speculation, extraction, resource control or commodification at the expense of agroecology, land stewardship, food sovereignty and human rights. It is sometimes also called land grabbing.

See ‘Grabbing (of wild species and space)’.

Sustainable use assessment
law of the sea

The United Nations Convention on the Law of the Sea (UNCLOS), in force since 1994, defines the rights and obligations of nations (167 at present) with regard to the use of the world's oceans and their resources, and the protection of the marine and coastal environment. The UNCLOS also defines national marine jurisdiction on maritime territories and provides guidelines related to the use and management of marine environment and resources.

Americas assessment
leakage effect

Phenomena whereby the reduction in emissions (relative to a baseline) in a jurisdiction/sector associated with the implementation of mitigation policy is offset to some degree by an increase outside the jurisdiction/sector through induced changes in consumption, production, prices, land use and/or trade across the jurisdictions/sectors. Leakage can occur at a number of levels, be it a project, state, province, nation or world region.

Global assessment (1st work programme)
learning (traditional and formal)

Learning refers to the process of knowledge and skills acquisition. Studies on learning have payed attention to the different ways people acquire knowledge, practices, and beliefs (i.e. imitation, copying, trial-and-error), but also to the dynamics of kn.

Global assessment (1st work programme)
learning (traditional and formal)

Learning refers to the process of knowledge and skills acquisition. Studies on learning have payed attention to the different ways people acquire knowledge, practices, and beliefs (i.e. imitation, copying, trial-and-error), but also to the dynamics of knowledge transmission, or the different sources from which knowledge, practices, and beliefs are passed from one individual to another (i.e. from parents, peers, teachers, prestigious peoples, media, etc.). Social learning is defined as the acquisition of new information by copying others, and it is a key human strategy that allows for the accumulation of culturally transmitted knowledge.

Sustainable use assessment
legal and regulatory instrument

see “Policy instruments”.

Sustainable use assessment
legal personality

any entity that has the ability to conclude and negotiate international agreements in accordance with its external commitments; become a member of international organizations; join international conventions, such as the European Convention on Human Rights, stipulated in Article 6(2) of the Treaty on European Union

Invasive alien species assessment
legal pluralism

Legal pluralism is a sensitizing concept for situations in which people draw upon several legal systems, irrespective of their status within the state legal system.

Sustainable use assessment
level of resolution

Degree of detail captured in an analysis. A high level of resolution implies a highly detailed analysis, usually associated with finer spatial and temporal scales. A low level of resolution implies a less detailed analysis, usually associated with coarser spatial and temporal scales.

Asia-Pacific assessment
life frames of nature’s values

Frames that illustrate the in which people conceptualise how nature matters. Life frames mediate between ways of being/living and the prioritization of different sets of broad and specific values. The four archetypes of living from, living in, living with and living as nature are not mutually exclusive. They offer a range of sources-of-concern for nature that can overlap or be emphasized in diverse contexts (section 2.2.6).

Land degradation and restoration assessment
living in harmony with nature

Within the context of the IPBES Conceptual Framework - a perspective on good quality of life based on the interdependence that exists among human beings, other living species and elements of nature. It implies that we should live peacefully alongside all other organisms even though we may need to exploit other organisms to some degree.

Asia-Pacific assessment, Europe and Central Asia assessment, Africa assessment, Americas assessment, Sustainable use assessment, Scenarios and models assessment
local

adj. Referring to places, people, things or events within a short distance of an identified locality.

Pollination assessment
local communities

Local communities” refers to non-indigenous communities with historical linkages to places and livelihoods characterized by long- term relationships with the natural environment, often over generations.

Sustainable use assessment
local community

A group of individuals that interact within their immediate surroundings and/or direct mutual influences in their daily life. In this sense, a rural village, a clan in transhumance or the inhabitants of an urban neighbourhood can be considered a local community, but not all the inhabitants of a district, a city quarter or even a rural town. A local community could be permanently settled or mobile.

Pollination assessment
local ecological knowledge

Knowledge about nature, including organisms (animals and plants), ecosystems and ecological interactions, held by local people who interact with and use natural resources. This is a manifestation of indigenous local knowledge (ILK), but includes also knowledge held by those local people who may not be officially recognized as indigenous (in legal terms). Like traditional ecological knowledge, LEK can be seen as a knowledge-practice-belief complex. In other words, it is a cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission (Berkes, 2012). This encompasses ways of knowing and doing, which are dynamic concepts relying on building on experience and adapting to changes, thereby imbibe a strong learning-by-doing component.

Sustainable use assessment
local economies

Local economies and subsistence economies are defined as those that are small in scale and in which the use of resources (including wild species) are limited and exclusively used to meet local needs rather than accumulated or sold for profit.

Sustainable use assessment
logging

Logging is defined as the removal of whole trees or woody parts of trees from their habitat. Logging generally results in the death of the tree, but also includes cases in which it may not, such as coppicing. Logging occurs in forests that may be classified as primary, naturally regenerating, planted, and plantation. This assessment does not address logging from plantation forests except as it has bearing on the practice in the other forest types. Harvest of non-woody parts of trees ( leaves, propagules and bark) are here defined as gathering.

Sustainable use assessment
radiative forcing

The measurement of the capacity of a gas or other forcing agents to affect that energy balance, thereby contributing to climate change. Put more simply, RF expresses the change in energy in the atmosphere due to GHG emissions.
