The state of having no protection from something potential harmful.

Asia-Pacific assessment
extensive forest management

Low or no input in regeneration or site amelioration is practiced in sparsely populated regions with large forest areas, such as boreal forests (Taiga) of Canada and Siberia, and across much of the world´s major tropical forest biomes.

extensive grazing

Extensive grazing is that in which livestock are raised on food that comes mainly from natural grasslands, shrublands, woodlands, wetlands, and deserts. It differs from intensive grazing, where the animal feed comes mainly from artificial, seeded pastures.

Asia-Pacific assessment, Americas assessment
extensive grazing (lands)

A form of grazing in which livestock are raised on food that comes mainly from natural grasslands, shrublands, woodlands, wetlands and deserts. It differs from intensive grazing, where the animal feed comes mainly from artificial, seeded pastures.

Scenarios and models assessment
externality

A positive or negative consequence (benefits or costs) of an action that affects someone other than the agent undertaking that action and for which the agent is neither compensated nor penalized through the markets.

Land degradation and restoration assessment, Europe and Central Asia assessment, Global assessment (1st work programme), Asia-Pacific assessment, Sustainable use assessment, Americas assessment
externality

an economic concept of uncompensated environmental effects of production and consumption that affect consumer utility and enterprise cost outside the market mechanism

Invasive alien species assessment
extinction

A population, species or more inclusive taxonomic group has gone extinct when all its individuals have died. A species may go extinct locally (population extinction), regionally ( extinction of all populations in a country, continent or ocean) or globally. Populations or species reduced to such low numbers that they are no longer of economic or functional importance may be said to have gone economically or functionally extinct, respectively. Species extinctions are typically not documented immediately: for example, the IUCN Red List categories and criteria require there to be no reasonable doubt that all individuals have died, before a species is formally listed as Extinct (see IUCN Red List).

Sustainable use assessment
extinction debt

The future extinction of species due to events in the past, owing to a time lag between an effect such as habitat destruction or climate change, and the subsequent disappearance of species.

extinction

A population, species or more inclusive taxonomic group has gone extinct when all its individuals have died. A species may go extinct locally (population extinction), regionally (e.g. extinction of all populations in a country, continent or ocean) or glo.

extinction

The evolutionary termination of a species caused by the failure to reproduce and the death of all remaining members of the species; the natural failure to adapt to environmental change.

Americas assessment
extractive practice

Extractive practices are defined as the temporary or permanent removal of organisms, part of them or materials derived from them, and may result in mortality of the individual to be used (hunting or whole plant harvest), but does not necessarily do so (e.g. limited collection of plant propagules or shearing and releasing of vicuna).

Sustainable use assessment
extractives

Hydrocarbons (oil and gas) and minerals.

Americas assessment
sacred grove

A particular type of sacred natural sites represented by patches of forest revered as sacred (Bhagwat & Rutte, 2006). Sacred groves may be revered e.g. as burial grounds (Mgumia & Oba, 2003) or sites of ancestral or deity worship (Ramakrishnan et al., 1998). There are locally-established rules that regulate how sacred groves can be used (Hughes & Chandran, 1998). Observation of those rules often contributes to the biodiversity conservation on those sites (Bhagwat & Rutte, 2006).

Sustainable use assessment
sacred natural sites

Areas of land or water that have special spiritual significance to peoples and communities. They consist of natural features, ranging from entire ecosystems, such as mountains, forests or islands, to single natural features such as a tree, spring or boulder, and are very important for the conservation of nature and culture. Sacred natural sites have been managed based on indigenous and local knowledge systems, developed over long periods of time, and are source of cultural identity.

satoyama initiative

A global initiative with the purpose of realizing societies in harmony with nature through the conservation and advancement of socio-ecological production landscapes and seascapes (SEPLS)” around the world.

Asia-Pacific assessment
satoyama-satoumi

Satoyama is the Japanese term for a socio-ecological production landscape (SEPL) represented by a mosaic of different ecosystem types: secondary forests, timber plantations, farmlands, irrigation ponds, and grasslands—along with human settlements. Satoyama is managed through the interaction between ecosystems and humans to create ecosystem services for human well-being. Satoumi refers to Japan's coastal areas where human interaction over time has resulted in a higher degree of productivity and biodiversity. Foundational to both concepts is the positing of a relationship of interaction between humans and their environment, coupled with the notion that properly maintained the relationship is mutually beneficial.

scale paradox

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

Land degradation and restoration assessment
scale

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).

scaling

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.

Scenarios and models assessment
scenario

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|.

Scenarios and models assessment
scenarios

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.

Values assessment
science-policy interface

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.

Americas assessment
scientific uncertainty

Imperfect knowledge or data on the system being described.

sea mount

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.

Asia-Pacific assessment
sea surface temperature

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.

Asia-Pacific assessment
sea-level rise

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

Asia-Pacific assessment
seascape

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.
