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.

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).

Pollination assessment
dry forest

Tropical and sub-tropical dry forests occur in climates that are warm year-round, and may receive several hundred centimetres or rain per year, they deal with long dry seasons which last several months and vary with geographic location.

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
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.

Global assessment (1st work programme), 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 (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.

Asia-Pacific assessment
land degradation

Refers to the many processes that drive the decline or loss in biodiversity, ecosystem functions or their benefits to people and includes the degradation of all terrestrial ecosystems.

Americas assessment, Sustainable use assessment, Africa assessment, Global assessment (1st work programme)

See ‘Grabbing (of wild species and space)’.

Sustainable use assessment
land grabbing

See ‘Large scale land acquisition'.

land grabbing

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.

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

Global assessment (1st work programme)
land use

The human use of a specific area for a certain purpose (such as residential, agriculture, recreation, industrial, etc.). Influenced by, but not synonymous with, land cover. Land-use change refers to a change in the use or management of land by humans, which may lead to a change in land cover.
