Concept Definition Deliverable(s)
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.

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
lag phase

the time between when an alien species arrives in a new area and the onset of the phase of rapid, or exponential, increase. Multiple factors are frequently implicated in the persistence or dissolution of the lag phase in biological invasions, including an initial shortage of suitable sites, the absence or shortage of essential mutualists, inadequate genetic diversity, and reduction in competition or predation (due to other alterations in the resident biota)

Invasive alien species assessment
land abandonment

Land abandonment occurs when a particular land use ceases, and there is no clearly- defined subsequent land use practice. It is often associated with poorly defined ownership and/or land use governance.

Land degradation and restoration assessment
land cover

The physical coverage of land, usually expressed in terms of vegetation cover or lack of it. Related to, but not synonymous with, land use.

Sustainable use assessment
land cover

The observed (bio)physical cover on the earth's surface.

Global assessment (1st work programme), Land degradation and restoration assessment
land cover

The physical coverage of land, usually expressed in terms of vegetation cover or lack of it. Related to, but not synonymous with, land use (Millenium Ecosystem Assessment, 2005).

land cover

The surface cover on the ground, whether vegetation, urban infrastructure, water, bare soil or other. Identifying, delineating and mapping land cover is important for global monitoring studies, resource management, and planning activities. Identification of land cover establishes the baseline from which monitoring activities (change detection) can be performed, and provides the ground cover information for baseline thematic maps.

Asia-Pacific assessment
land degradation

Refers to the many processes that drive the decline or loss in biodiversity, ecosystem functions or their benefits to people and includes the degradation of all terrestrial ecosystems.

Americas assessment, Sustainable use assessment, Africa assessment, Global assessment (1st work programme)

Sustainable use assessment
land grabbing

See ‘Large scale land acquisition'.

land grabbing

The large-scale acquisition of land (especially in developing countries), driven primarily by concerns about food and energy security of high-income countries and often executed by the private sector.

Land degradation and restoration assessment
land sharing and sparing

Concepts used to describe, in general terms, spatial-temporal arrangements of agricultural and non-agricultural areas. Land sharing is a situation where farming practices enable biodiversity to be maintained within agricultural landscapes. Land sparing, also called land separation involves restoring or creating non-farmland habitat in agricultural landscapes at the expense of field-level agricultural production - for example, woodland, natural grassland, wetland, and meadow on arable land. This approach does not necessarily imply high-yield farming of the non-restored, remaining agricultural land. See also 'Conservation agriculture'.

land sharing

A situation where low-yield farming enables biodiversity to be maintained within agricultural landscapes.

Land degradation and restoration assessment, Americas assessment, Europe and Central Asia assessment
land sparing

Also called Land separation involves restoring or creating non-farmland habitat in agricultural landscapes at the expense of field-level agricultural production - for example, woodland, natural grassland, wetland, and meadow on arable land. This approach does not necessarily imply high- yield farming of the non restored, remaining agricultural land. (From Rey Benayas & Bullock, 2012). See also Conservation agriculture in this Glossary.

Americas assessment
land sparing

Land sparing, also called land separation involves restoring or creating non-farmland habitat in agricultural landscapes at the expense of field-level agricultural production - for example, woodland, natural grassland, wetland, and meadow on arable land. This approach does not necessarily imply high-yield farming of the non-restored, remaining agricultural land. See also Conservation agriculture.

Pollination assessment
landscape socio-ecological approach

The landscape scale approach incorporates the socio-ecological system, including natural and human-modified ecosystems, influenced by ecological, historical, economic, and socio-cultural processes. The landscape includes an array of stakeholders small enough to be manageable, but large enough to deliver multiple functions for stakeholders with differing interests.

A human-defined area ranging in size from c. 3 km2 to c. 3002 km. Landscape is spatially heterogeneous in at least one factor of interest and often consists of a mosaic of interacting ecosystems.

Land degradation and restoration assessment
landscape

An area delineated by an actor for a specific set of objectives, constitutes an area in which entities, including humans, interact according to rules (physical, biological, and social) that determine their relationships; Place-based systems that result from interactions between people, land, institutions (laws, rules and regulations) and values. Interactive aspects that define a landscape are functional interactions, negotiated spaces and multiple scales.

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.
