IPBES core glossary

Ecosystem characterized by a continuous layer of herbaceous plants, mostly grasses, and a discontinuous upper layer of trees that may vary in density.

Sawnwood is defined as planks, sleepers (cross-ties), beams, joists, boards, rafters, 1679 scantlings, laths, boxboards and lumber that exceed 5 mm in thickness.

Process in which land use outcomes vary (often counterintuitively) according to the geographic location and spatial scale under consideration.

The spatial, temporal, quantitative and analytical dimensions used to measure and study any phenomenon. The temporal scale is comprised of two properties: (i) temporal extent - the total length of the time period of interest for a particular study (e.g. 10 years, 50 years, or 100 years); and 2) temporal grain (or resolution) - the temporal frequency with which data are observed or projected within this total period (e.g. at 1-year, 5-year or 10- year intervals). The spatial scale is comprised of two properties: 1) spatial extent - the size of the total area of interest for a particular study (e.g. a watershed, a country, the entire planet); and (ii) spatial grain (or resolution) - the size of the spatial units within this total area for which data are observed or predicted (e.g. fine-grained or coarse-grained grid cells).

Bringing model outputs to the appropriate scale, which can be done in two different directions: upscaling information from local, fine-grained resolution to global, coarse-grained resolution; or vice versa downscaling coarse-grained information to a finer resolution.

Representations of possible futures for one or more components of a system, particularly for drivers of change in nature and nature's benefits, including alternative policy or management options. Exploratory scenarios (also known as explorative scenarios or descriptive scenarios) are scenarios that examine a range of plausible futures, based on potential trajectories of drivers - either indirect (e.g. socio-political, economic and technological factors) or direct (e.g. habitat conversion, climate change). Target-seeking scenarios (also known as goal-seeking scenarios or normative scenarios): scenarios that start with the definition of a clear objective, or a set of objectives, specified either in terms of achievable targets, or as an objective function to be optimized, and then identify different pathways to achieving this outcome (e.g. through backcasting). Intervention scenarios are scenarios that evaluate alternative policy or management options - either through target seeking (also known as goal seeking or normative scenario analysis) or through policy screening (also known as ex-ante assessment). Policy-evaluation scenarios are scenarios, including counterfactual scenarios, used in ex-post assessments of the gap between policy objectives and actual policy results, as part of the policy-review phase of the policy cycle. Policy-screening scenarios are scenarios used in ex-ante assessments, to forecast the effects of alternative policy or management options (interventions) on environmental outcomes.|scale|.

Quantitative or qualitative exploration of future pathways through use of scenarios.

Representations of possible futures for one or more components of a system, particularly, in this assessment, for drivers of change in nature and nature’s benefits, including alternative policy or management options. Exploratory scenarios (also known as “explorative scenarios” or “descriptive scenarios”) are scenarios that examine a range of plausible futures, based on potential trajectories of drivers - either indirect (socio-political, economic and technological factors) or direct (e.g. habitat conversion, climate change).

Scenarios are representations of different possible futures from a defined starting point. They are focused on highlighting or exploring drivers of change and the impacts of changes in these over a specified time frame. In doing so they enable decision-makers to anticipate potential changes and develop timely responses to these.

Environment-related SPIs are organizations, initiatives or projects that work at the boundary of science, policy and society to enrich decision making, shape their participants’ and audiences’ understandings of problems, and so produce outcomes regarding decisions and behaviours.

Imperfect knowledge or data on the system being described.

Any form of ice found at sea which has originated from the freezing of sea water (sea ice does not include superstructure icing). Ice formed from the freezing of the waters of the Great Lakes will be considered the same as sea ice.

A seamount is a mountain rising from the ocean seafloor that does not reach to the water’s surface (sea level), and thus is not an island. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000-4,000 m (3,300- 13,100 ft) in height.

Sea surface temperature (SST) is the water temperature close to the ocean’s surface. The exact meaning of surface varies between 1mm and 20 metres below the sea surface.

The average height of the ocean’s surface is higher than the daily changes of the tides.

Seascape can be defined as a spatially heterogeneous area of coastal environment (i.e. intertidal, brackish) that can be perceived as a mosaic of patches, a spatial gradient, or some other geometric patterning. The tropical coastal “seascape” often includes a patchwork of mangroves, seagrass beds, and coral reefs that produces a variety of natural resources and ecosystem services.

adj. Pertaining to particular season (spring, summer, autumn, winter, rainy, dry etc.) or recurring in relation to particular seasons.

Regenerating forest after disturbance, such as fire or clear-cutting (IUCN, 2012a).

Regenerating forest after disturbance, such as fire or clear-cutting.

A distinct part of society, or of a nation's economy.

The process by which a nomadic group transitions to a lifestyle of living in one place.

Refers to the upper part of continental slopes. See 'Continental slope'.

The effect of any feature of the environment that results in natural selection, e.g. food shortage, predator activity, competition from members of the same or other species (Lawrence, 2005).

Selective hunting, in this assessment, refers to situations where hunters focus on particular species, or on individual animals within a population that have particular attributes, e.g. large size, large horns or antlers.

Extracting one or a few tree species instead of for example clearcutting of forests. Trees are only felled when they reach a particular height. This allows young trees a guaranteed life span and the forest will regain full maturity after around 30-50 years.

An ecosystem with most of its processes and biodiversity intact, though altered by human activity in strength or abundance relative to the natural state.

Characteristics that make a place special or unique, as well as to those that foster a sense of authentic human attachment and belonging (Casey, 2001).
