Glossary definitions

An Exclusive Economic Zone (EEZ) is a concept adopted at the Third United Nations Conference on the Law of the Sea (1982), whereby a coastal State assumes jurisdiction over the exploration and exploitation of marine resources in its adjacent section of the continental shelf, taken to be a band extending 200 miles from the shore. The Exclusive Economic Zone comprises an area which extends either from the coast or in federal systems from the seaward boundaries of the constituent states (3 to 12 nautical miles, in most cases) to 200 nautical miles (370 kilometers) off the coast. Within this area, nations claim and exercise sovereign rights and exclusive fishery management authority over all fish and all Continental Shelf fishery resources.

The satisfaction obtained from knowing that nature endures.

Drivers that might affect the outcome of a given policy or decision-making process but are not amenable to influence by that process, and which typically operate at broader spatial scales.

A pollinator that is transported and introduced accidentally or deliberately by human beings outside its native distributional range.

See Alien species.

Anyone who has acquired good knowledge of a subject through her/his life experience, including local or indigenous knowledge holders in addition to scientists. It is assumed that the expert is a reliable source of information within a specific domain.

Models in which experience of experts and stakeholders is used to describe relationships between input and output variables.

The consumptive use of any natural resources.

See scenario.

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).

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).

The state of having no protection from something potential harmful.

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 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.

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.

see spatial scale and temporal scale”.

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.

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

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).

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.

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.

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.

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).

Hydrocarbons (oil and gas) and minerals.

The place or type of site where an organism or population naturally occurs. Also used to mean the environmental attributes required by a particular species or its ecological niche.

The degree to which the landscape facilitates the movement of organisms (animals, plant reproductive structures, pollen, pollinators, spores, etc.) and other environmentally important resources (e.g. nutrients and moisture) between similar habitats. Connectivity is hampered by fragmentation (q.v.).

A general term describing the set of processes by which habitat quality is reduced. Habitat degradation may occur through natural processes (e.g. drought, heat, cold) and through human activities (forestry, agriculture, urbanization).

The ability of soil or soil materials to serve as a habitat for micro-organisms, plants, soil- living animals and their interactions.

A general term describing the set of processes by which habitat loss results in the division of continuous habitats into a greater number of smaller patches of lesser total and isolated from each other by a matrix of dissimilar habitats. Habitat fragmentation may occur through natural processes (e.g. forest and grassland fires, flooding) and through human activities (forestry, agriculture, urbanization).

The number of different habitats in a landscape.

A general term describing the set of processes by which habitat quality is reduced. Habitat degradation may occur through natural processes (e.g. drought, heat, cold) and through human activities (forestry, agriculture, urbanization).

Changes in an area's primary ecological functions and species composition due to human activity and/or non-native species invasion.

The importance of ecosystems to provide living space for resident and migratory species (thus maintaining the gene pool and nursery service).

Species that require very specific habitats and resources (e.g. narrow range of food sources or cover types) to thrive and reproduce.

The place or type of site where an organism or population naturally occurs.

the area, characterized by its abiotic and biotic properties, that is habitable by a particular species

They occur when colonies of algae (simple plants that live in the sea and freshwater) grow out of control and produce toxic or harmful effects on people, fish, shellfish, marine mammals and birds.

Harmful algal blooms (HABs) occur when colonies of algae grow out of control and produce toxic or harmful effects on people, fish, shellfish, marine mammals and birds. The human illnesses caused by HABs, though rare, can be debilitating or even fatal.

The process of bringing together, and comparing, models or scenarios to make them compatible or consistent with one another.

The process of bringing something together, and comparing (e.g. models or scenarios) to facilitate compatibility or consistency.

A process, phenomenon or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or environmental degradation. Hazards that this assessment discusses are mostly environmental hazards (chemical, natural and biological hazards), while cognizant that many hazards are socio- natural, in that they are associated with a combination of natural and anthropogenic factors. Natural hazards are predominantly associated with natural processes and phenomena, including geological or geophysical hazards that originate from internal earth processes (earthquakes, volcanic activities, landslides, tsunamis), and hydrometeorological hazards, which are of atmospheric, hydrological or oceanographic origin (tropical cyclones, floods, drought; heatwaves, and storm surges). Biological hazards are of organic origin or conveyed by biological vectors, including pathogenic microorganisms, toxins and bioactive substances. Examples are bacteria, viruses or parasites, as well as venomous wildlife and insects, poisonous plants and mosquitoes carrying disease-causing agents.

Describes built up areas that are hotter than nearby rural areas. Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water quality.
