Global assessment (1st work programme)
moral economy

A moral economy, initially based on peasants’ sense of belonging and sharing, is an economy that is based on goodness, fairness, and justice. Such an economy is generally only stable in small, closely knit communities, where the principles of mutuality operate.

Land degradation and restoration assessment
mosaic landscape

A pattern of landscapes with multiple patches and corridors.

Europe and Central Asia assessment
mosaic restoration

Landscape scale restoration efforts that do not rely on a single restoration mechanism for an entire landscape, or it is a single mechanism, deploying it in a spatially variable manner that creates patches of restored and non-restored landscape units.

Land degradation and restoration assessment
mother earth

An expression used in a number of countries and regions to refer to the planet Earth and the entity that sustains all living things found in nature with which humans have an indivisible, interdependent physical and spiritual relationship.

Scenarios and models assessment, Global assessment (1st work programme), Asia-Pacific assessment, Sustainable use assessment
mother earth

An expression used in a number of countries and regions to refer to the planet Earth and the entity that sustains all living things found in nature with which humans have an indivisible, interdependent physical and spiritual relationship (see nature).

Land degradation and restoration assessment, Europe and Central Asia assessment, Africa assessment, Americas assessment
motivation

One’s general willingness to do something. It is the set of psychological forces that compel you to take action. Motivation can be extrinsic - based on changes in external conditions, external rewards. Intrinsic motivation refers to an inherent drive to seek out challenges and new possibilities.

Values assessment
motivation crowding

Providing extrinsic incentives for certain kinds of behaviour - such as promising monetary rewards for accomplishing more of intrinsically/ normatively motivated action - can undermine that motivation for performing the behaviour, diminished motivation to act.

Values assessment
multi stakeholder based scenario development

See Participatory scenario development.

Asia-Pacific assessment
multi-criteria analysis

A sub-discipline of operations research that explicitly evaluates multiple conflicting criteria in decision-making.

Asia-Pacific assessment
multidisciplinary expert panel

The IPBES Multidiscplinary Expert Panel is a subsidiary body established by the IPBES Plenary which oversees the scientific and technical functions ofthe Platform, a key role being to select experts to carry out assessments.

Europe and Central Asia assessment, Sustainable use assessment, Americas assessment
multidisciplinary expert panel

Within the context of IPBES - a subsidiary body established by the IPBES Plenary which carries out the scientific and technical functions agreed upon by the Plenary, as articulated in the document on functions, operating principles and institutional arrangements of IPBES.

Scenarios and models assessment
multifunctional ‘scape

where ‘scape is shorthand for ‘land-, freshwater- and sea-scape’, is a contiguous area defined by major geomorphological (e.g. major watersheds, geological systems and major biomes) and/or oceanographic processes (major current regimes, biogeochemical processes). Scale may vary with the application. A ‘scape may include a mosaic of habitats across all conditions of nature from intact in ‘wild spaces’, through modified and altered in ‘shared spaces’ where humans have a significant impact on the biota and may alter function considerably, to ‘anthromes’ or fully transformed agricultural and urban areas where the coverage of natural habitats is very low or even zero.

IPBES-IPCC co-sponsored workshop on biodiversity and climate change
multifunctional agriculture

The concept was adopted by FAO (1999) to foster an approach integrating landscape, biological connections, and less damageable practices. Multifunctional agriculture is meant to integrate the economic, social and ecological aspects of land management.

Land degradation and restoration assessment
multifunctionality

The condition of being multifunctional; diversity of function.

Global assessment (1st work programme)
uncertainty

Any situation in which the current state of knowledge is such that: the order or nature of things is unknown, the consequences, extent, or magnitude of circumstances, conditions, or events is unpredictable, and credible probabilities to possible outcomes cannot be assigned. Uncertainty can result from lack of information or from disagreement about what is known or even knowable. Uncertainty can be represented by quantitative measures (e.g., a range of values calculated by various models) or by qualitative statements (e.g., reflecting the judgment of a team of experts).

units of analysis

The IPBES Units of Analysis result from subdividing the Earth’s surface into units solely for the purposes of analysis. The following have been identified as IPBES units of analysis globally: Terrestrial: Tropical and subtropical dry and humid forests Temperate and boreal forests and woodlands Mediterranean forests, woodlands and scrub Tundra and High Mountain habitats Tropical and subtropical savannas and grasslands Temperate Grasslands Deserts and xeric shrublands Wetlands - peatlands, mires, bogs Urban/Semi-urban Cultivated areas (incl. cropping, intensive livestock farming etc.) Aquatic, including both marine and freshwater: Cryosphere Aquaculture areas Inland surface waters and water bodies/freshwater Shelf ecosystems (neritic and intertidal/littoral zone) Open ocean pelagic systems (euphotic zone) Deep-Sea Coastal areas intensively used for multiple purposes by humans These IPBES terrestrial and aquatic units of analysis serve as a framework for comparison within and across assessments and represent a pragmatic solution. The IPBES terrestrial and aquatic units of analysis are not intended to be prescriptive for other purposes than those of IPBES assessments. They are likely to evolve as the work of IPBES develops.

upwelling

A process in which deep, cold water rises toward the surface replacing warmer water pushed away by winds. Water that rises to the surface as a result of upwelling is typically colder and rich in nutrients, which “fertilize” surface waters, meaning that these surface waters often have high biological productivity.

adj. Pertaining to the built-up, human- inhabited environment (cities, towns, villages, etc.).

Pollination assessment
urban ecosystem

Any ecological system located within a city or other densely settled area or, in a broader sense, the greater ecological system that makes up an entire metropolitan area (Pickett, 2018).

urbanization

The increase in the proportion of a population living in urban areas; the process by which a large number of people becomes permanently concentrated in relatively small areas, forming cities.

The wild species uses are defined through the practices of fishing, gathering, terrestrial animal harvesting, logging, and non-extractive practices. For the purposes of this assessment, the use of wild species have been divided into different categories, which are not mutually exclusive: ceremony and ritual expression, decorative and aesthetic, energy, food and feed, learning and education, materials and construction, medicine and hygiene, recreation and other: companionship.
