Concept Definition Deliverable(s)
driver

In the context of IPBES, drivers of change are all the factors that, directly or indirectly, cause changes in nature, anthropogenic assets, nature's contributions to people and a good quality of life. Direct drivers of change can be both natural and anthropogenic. Direct drivers have direct physical (mechanical, chemical, noise, light etc.) and behaviour-affecting impacts on nature. They include, inter alia, climate change, pollution, different types of land use change, invasive alien species and zoonoses, and exploitation. Indirect drivers are drivers that operate diffusely by altering and influencing direct drivers, as well as other indirect drivers. They do not impact nature directly. Rather, they do it by affecting the level, direction or rate of direct drivers. Interactions between indirect and direct drivers create different chains of relationship, attribution, and impacts, which may vary according to type, intensity, duration, and distance. These relationships can also lead to different types of spill-over effects. Global indirect drivers include economic, demographic, governance, technological and cultural ones. Special attention is given, among indirect drivers, to the role of institutions (both formal and informal) and impacts of the patterns of production, supply and consumption on nature, nature's contributions to people and good quality of life.

driver

In the context of IPBES, drivers of change are all the factors that, directly or indirectly, cause changes in nature, anthropogenic assets, nature's contributions to people and a good quality of life. Direct drivers of change can be both natural and anthropogenic. Direct drivers have direct physical (mechanical, chemical, noise, light etc.) and psychological (disturbance etc.) impacts on nature and its functioning, and on people and their interaction. Direct drivers unequivocally influence biodiversity and ecosystem processes. They are also referred to as ‘pressures'. Direct drivers include, inter alia, climate change, pollution, land use change, invasive alien species and zoonoses, including their effects across regions. Indirect drivers are drivers that operate diffusely by altering and influencing direct drivers as well as other indirect drivers (also referred to as ‘underlying causes'). Interactions between indirect and direct drivers create different chains of relationship, attribution, and impacts, which may vary according to type, intensity, duration, and distance. These relationships can also lead to different types of spill-over effects. Global indirect drivers include economic, demographic, governance, technological and cultural ones, among others. Special attention is given, among indirect drivers, to the role of institutions (both formal and informal) and impacts of the patterns of production, supply and consumption on nature, nature's contributions to people and good quality of life.

Land degradation and restoration assessment
drivers (direct)

Drivers, both non human-induced and anthropogenic, that affect nature directly. Direct anthropogenic drivers are those that flow from human institutions and governance systems and other indirect drivers. They include positive and negative effects, such as habitat conversion, human-caused climate change, or species introductions. Direct non human-induced drivers can directly affect anthropogenic assets and quality of life (e.g. a volcanic eruption can destroy roads and cause human deaths), but these impacts are not the main focus of IPBES. See chapter 1 and chapter 2 (Drivers) for a detailed typology of drivers.

Global assessment (1st work programme)
drivers (indirect)

Human actions and decisions that affect nature diffusely by altering and influencing direct drivers as well as other indirect drivers. They do not physically impact nature or its contributions to people. Indirect drivers include economic, demographic, governance, technological and cultural ones, among others. See chapter 1 and chapter 2 (Drivers) for a detailed typology of drivers.

Global assessment (1st work programme)
drivers of change

All the external factors that cause change in nature, anthropogenic assets, nature's benefits to people and a good quality of life. They include institutions and governance systems and other indirect drivers, and direct drivers (both natural and anthropogenic).

Scenarios and models assessment, Pollination assessment
drivers of change

All those external factors (i.e. generated outside the conceptual framework element in question) that affect nature, anthropogenic assets, nature's benefits to people and quality of life. Drivers of change include institutions and governance systems and other indirect drivers, and direct drivers - both natural and anthropogenic.direct drivers result from human decisions.

drivers of change

Drivers of change refer to all those external factors that affect nature, and, as a consequence, also affect the supply of nature's contributions to people. The IPBES conceptual framework includes drivers of change as two of its main elements: indirect drivers, which are all anthropogenic, and direct drivers, both natural and anthropogenic. See chapter 1 and chapter 2 (Drivers) for a detailed typology of drivers.

Sustainable use assessment
driver

For the purpose of this assessment, drivers are defined as the factors that, directly or indirectly influence the sustainability of use of wild species, by changing the abundance or distribution of species in use, altering demand on and consumption of wild species, products derived from wild species and/or changing the (nature, scale, and/or intensity of) interactions with wild species in use (practices). It is recognized that the same factor may influence different components of the system (wild species, practices, Nature’s contributions to people); and the interactions among these factors vary across time and space, which can have negative or positive effects on sustainability.

Sustainable use assessment
drivers, anthropogenic direct

Those that are the result of human decisions and actions, namely, of institutions and governance systems and other indirect drivers (e.g. land degradation and restoration, freshwater pollution, ocean acidification, climate change produced by anthropogenic carbon emissions, species introductions). Some of these drivers, such as pollution, can have negative impacts on nature; others, as in the case of habitat restoration, can have positive effects.

Pollination assessment
drivers (direct)

Both natural and anthropogenic drivers that affect nature directly.

Pollination assessment
drivers, institutions and governance systems and other indirect drivers

The ways in which societies organize themselves (and their interaction with nature), and the resulting influences on other components. They are underlying causes of change that do not make direct contact with the portion of nature in question; rather, they impact it - positively or negatively - through direct anthropogenic drivers. The institutions encompass all formal and informal interactions among stakeholders and social structures that determine how decisions are taken and implemented, how power is exercised, and how responsibilities are distributed. Various collections of institutions come together to form governance systems, that include interactions between different centres of power in society (corporate, customary-law based, governmental, judicial) at different scales from local through to global. Institutions and governance systems determine, to various degrees, the access to, and the control, allocation and distribution of components of nature and anthropogenic assets and their benefits to people .

Pollination assessment
drivers, natural direct

Drivers that are not the result of human activities and whose occurrence is beyond human control (e.g. natural climate and weather patterns, extreme events such as prolonged drought or cold periods, cyclones and floods, earthquakes, volcanic eruptions).

Land degradation and restoration assessment
dynamic downscaling

Downscaling based on mechanistic models, which may be more appropriate than statistical downscaling in systems where the relationship between coarse scale and fine scale dynamics are complex and non-linear, or observational data are insufficient.

Scenarios and models assessment
dynamic model

A model that describes changes through time of a specific process. See also process-based model.

Scenarios and models assessment
dynamic model

See models.

dynamics and processes

refer to the emergent patterns of change across ‘depths’, ‘breadths’ and time that unfold as non-linear pathways. These may be characterised by ‘punctuated equilibrium’ in which more stable periods of incremental change are punctuated by bursts of change in which underlying structures are reorganised into new states.

Values assessment
fallow

Land normally used for production and left to recover for part or all of a growing season (more in the case of swidden agriculture).

Sustainable use assessment, Global assessment (1st work programme)
family forestry

Family forestry is forest tenure and activities by persons with ownership or tenure rights to forest land. Persons owning or managing forests often include the whole family in the activities and the forest land goes from one generation to the next.

Global assessment (1st work programme)
farm

An area of land, a holding of any size from a small plot or garden (fractions of a hectare) to several thousand hectares that is devoted primarily to agriculture to produce food, fibre, or fuel. A farm may be owned and operated by an individual, family, community, corporation or a company, and may produce one to many types of produce or animal.

Pollination assessment
feedback

The modification or control of a process or system by its results or effects.

Sustainable use assessment, Americas assessment, Europe and Central Asia assessment, Asia-Pacific assessment, Africa assessment
feedback loops

processes that either amplify (positive feedback loop) or diminish (negative feedback loop) the effects of a biological invasion. Feedback loops may make the impacts of biological invasions stronger or weaker, starting a chain reaction that repeats again and again. Negative feedback loop: A human-natural feedback that continually stabilizes or reduces ongoing or future biological invasions (also known as a ‘balancing’ feedback loop). Positive feedback loop: A human-natural feedback that continually increases ongoing or future biological invasions (also known as ‘exacerbating’ or ‘reinforcing’ feedback loops)

Invasive alien species assessment
feral

Species are considered to be feral if they or their ancestors were formerly domesticated, but they are now living independently of humans.

Sustainable use assessment
field

In agriculture, it is a defined area of cleared enclosed land used for cultivation or pasture.

Pollination assessment
fire regime

A term used to describe the characteristics of fires that occur in a particular ecosystem over a period of time. Fire regimes are characterized based on a combination of factors including the frequency, intensity, size, pattern, season and severity of fires.

Land degradation and restoration assessment
fire-stick farming

The practice of indigenous Australians to use fire to burn vegetation to facilitate hunting and to change the composition of the plant and animal species of an area. It was coined by Australian archaeologist Rhys Jones.

Asia-Pacific assessment
fishery

A unit determined by an authority or other entity that is engaged in raising and/or harvesting fish. Typically, the unit is defined in terms of some or all of the following: people involved, species or type of fish, area of water or seabed, method of fishing, class of boats and purpose of the activities.

Global assessment (1st work programme)
fishery

Generally, a fishery is an activity leading to harvesting of fish. It may involve capture of wild fish or raising of fish through aquaculture. Note that in this definition, the term fish includes all types of marine animals, fish, but also crustaceans, mollusks, echinoderms etc.

Sustainable use assessment
fishing

Fishing is defined as the removal from their habitats of aquatic animals (vertebrates and invertebrates) that spend their full life cycle in water (fish, some marine mammals, shellfish, shrimps, squids, corals). Fishing most often results in the death of the aquatic animal, but it may not in some cases. To reflect both situations, fishing has been sub-divided into a lethal and a “non-lethal” category. Lethal fishing is defined as the general and more usual meaning of fishing that leads to the killing of the animal, such as in traditional commercial fisheries. “Non-lethal fishing is defined as the temporary or permanent capture of live animals from their habitat without intended mortality, such as in aquarium fish trade or catch and release. However, unintended mortality may occur in “non-lethal” fishing and the term “non-lethal” is therefore put in quotes. The killing of species that spend part of their life cycle in terrestrial environments (e.g. walrus, sea turtles) is encompassed by the definition of hunting.

Sustainable use assessment
fitness (ecology)

Fitness involves the ability of organisms- or populations or species- to survive and reproduce in the environment in which they find themselves, and thus contribute genes to the next generation (Orr, 2009).

Global assessment (1st work programme)

Asia-Pacific assessment
flower strip

Linear areas of land within or at the edges of fields, farms, or other areas (rights of way, riparian areas, etc.) where flowering plants are seeded and encouraged to grow, often for the benefit of pollinators and other wildlife (q.v. insectory strips).

Pollination assessment
flower-visitor

An animal that visits flowers (a.k.a. anthophile) but is not necessarily a pollinator.

Pollination assessment
flowering plant

Plants that are characterized by producing flowers, even if inconspicuous. They are collectively called Angiosperms and include most plants grown for food and fibre.
