great acceleration

Great Acceleration refers to the acceleration of human-induced changes of the second half of the 20th century, unique in the history of human existence. Many human activities reached take-off points and sharply accelerated towards the end of the century.

Global assessment (1st work programme)
green bonds

A mode of private financing that tap the debt capital market through fixed income instruments (i.e. bonds) to raise capital to finance climate-friendly projects in key sectors of, but not limited to, transport, energy, building and industry, water, agriculture and forestry and waste.

Global assessment (1st work programme), Sustainable use assessment
green growth

Green growth means fostering economic growth and development while ensuring that natural assets continue to provide the resources and environmental services on which our well-being relies.

Global assessment (1st work programme)
green hunting

Green hunting occurs with tranquilizer dart guns and the animals are released alive. This is typically performed for veterinary procedures or translocation, and has been suggested as an alternative to lethal forms of hunting.

Sustainable use assessment
green infrastructure

Green infrastructure refers to the natural or semi-natural systems (e.g. riparian vegetation) that provide services for water resources management with equivalent or similar benefits to conventional (built) “grey” infrastructure (e.g. water treatment plants).

Global assessment (1st work programme)
green public procurement

A process whereby public authorities seek to procure goods, services and works with a reduced environmental impact throughout their life-cycle when compared to goods, services and works with the same primary function that would otherwise be procured.

Asia-Pacific assessment
green revolution

Period of food crop productivity growth that started in the 1960s due to a combination of high rates of investment in crop research, infrastructure, and market development and appropriate policy support, and whose environmental impacts have been mixed: on one side saving land conversion to agriculture, on the other side promoting an overuse of inputs and cultivation on areas otherwise improper to high levels of intensification, such as slopes.

Sustainable use assessment
green revolution

A set of research and the development of technology transfer initiatives occurring between the 1930s and the late 1960s (with prequels in the work of the agrarian geneticist Nazareno Strampelli in the 1920s and 1930s), that increased agricultural production worldwide, particularly in the developing world, beginning most markedly in the late 1960s. The initiatives resulted in the adoption of new technologies, including: new, high- yielding varieties (HYVs) of cereals, especially dwarf wheats and rices, in association with chemical fertilizers and agro-chemicals, and with controlled water-supply (usually involving irrigation) and new methods of cultivation, including mechanization. All of these together were seen as a package of practices to supersede traditional technology and to be adopted as a whole.

green water

Water transpired through plants to the atmosphere.

Land degradation and restoration assessment
greenhouse gas

Those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth’s surface, the atmosphere, and clouds. This property causes the greenhouse effect.

Land degradation and restoration assessment
greenhouse gas

Greenhouse gases are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of terrestrial radiation emitted by the Earth’s surface, the atmosphere itself, and by clouds. This property causes the greenhouse effect. Water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3) are the primary greenhouse gases in the Earth’s atmosphere. Moreover, there are a number of entirely human-made greenhouse gases in the atmosphere, such as the halocarbons and other chlorine- and brominecontaining substances, dealt with under the Montreal Protocol. Beside CO2, N2O and CH4, the Kyoto Protocol deals with the greenhouse gases sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs).

Global assessment (1st work programme)
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.

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.

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'.

Global assessment (1st work programme)
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.

Europe and Central Asia assessment, Land degradation and restoration assessment
land tenure

The relationship, whether legally or customarily defined, among people, as individuals or groups, with respect to land.

Land degradation and restoration assessment
land transformation

A process whereby the biotic community of an area is substantially altered or substituted by another, along with the underlying ecological and human processes responsible for its persistence, often as a result of a deliberate decision to change the purpose for which the land is used.

Land degradation and restoration assessment

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.

Land degradation and restoration assessment

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.
