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.

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
drylands

Arid, semi-arid and dry sub-humid areas. The term excludes hyper-arid areas, also known as deserts. Drylands are characterized by water scarcity and cover approximately 40% of the world's terrestrial surface.

drylands

Tropical and temperate areas with an aridity index (annual rainfall/annual potential evaporation) of less than 0.65.

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
kelp

A large brown seaweed that typically has a long, tough stalk with a broad frond divided into strip.

Asia-Pacific assessment
key biodiversity area

Sites contributing significantly to the global persistence of biodiversity. They represent the most important sites for biodiversity worldwide, and are identified nationally using globally standardised criteria and thresholds.

key players

People and organizations who both can influence and become affected by decisions - that is, in certain contexts, they serve as influencers, while at the same time are involved in actual decision making.

Values assessment
keystone species

A species whose impact on the community or ecosystem is disproportionately large relative to its abundance. Effects can be produced by consumption (trophic interactions), competition, mutualism, dispersal, pollination, disease, or habitat modification (non-trophic interactions).

keystone species

Species that maintain the organization and diversity of their ecological communities and are thus exceptional, relative to the rest of the community, in their importance. Species that, despite low biomass, exert strong effects on the structure of the communities they inhabit.

Asia-Pacific assessment
kinship-centric principle (non-humans)

animals, plants and spirits, and such approach forms part of an indigenous cultural identity. Maintaining reciprocal and healthy relationships through a continuum with animals, plants and the lands where they reside involve the giving and taking of resources in appropriate ways, at appropriate times. In some cases, animals and plants are seen and treated as equals to humans and shape and reshape human relations with nature. Often, the values embedded in these relationships drive human behaviour and are elicited through certain valuation methods. Appreciation (no disregard) for spiritual entities (e.g. sacred mountains, rivers, among others) residing on ancestral lands, can be an example of a Kinship-central approach (focused on non-humans).

Values assessment
kinship-centric principle (other humans)

Actions of mutual support between humans such as sharing, gender equity, social equity, honesty, humility, modesty. Some of these elements can be revealed as relevant through valuation methods and approaches, as well as by practices associated with them.

Values assessment
knowledge system

Indigenous and local knowledge systems are understood to be dynamic bodies of integrated, holistic, social and ecological understandings, know-hows, practices and beliefs pertaining to the relationship of living beings, including people, with one another and with their environment. Indigenous and local knowledge is grounded in territory, is highly diverse and is continuously evolving through the interaction of experiences, skills, innovations and different types of wisdom expressed in multiple ways (written, oral, visual, tacit, practical and scientific). Such knowledge can provide information, methods, theory and practice for sustainable ecosystem management. Indigenous and local knowledge systems have been, and continue to be, empirically tested, applied, contested and validated through different means in different contexts. Western Academic knowledge systems relate to often explicit knowledge that has been derived from applying formal methods in academic or technical institutions.
