IPBES core glossary

The IPBES core glossary provides a standard definition for important terms of broad applicability to IPBES outputs. This core glossary does not replace the assessment-specific glossaries, but is complementary to them. It was developed by a glossary committee established for this purpose.

overexploitation

Overexploitation means harvesting species from the wild at rates faster than natural populations can recover. Includes overfishing, and overgrazing.

overexploitation_1

Harvesting species from the wild at rates faster than natural populations can recover. Includes overfishing, and overgrazing.

overgrazing

Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals.

overgrazing_1

An excess of herbivory that leads to degradation of plant and soil resources.

overstocking

Placing a number of animals on a given area that will result in overuse if continued to the end of the planned grazing period.

paired catchment

Paired catchment studies have been widely used to assess the likely impact of land use change on water yield around the world. Such studies involve the use of two catchments (drainage basins) with similar characteristics in terms of slope, aspect, soils, area, precipitation and vegetation located adjacent to each other. Following a calibration period, where both catchments are monitored, one of the catchments is subjected to treatment and the other remains as a control. This allows the climatic variability to be accounted for in the analysis. The change in water yield can then be attributed to changes in vegetation. The paired catchment studies reported in the literature can be divided into four broad categories: (i) afforestation experiments; (ii) regrowth experiments; (iii) deforestation experiments; and (iv) forest conversion experiments.

paleological data

Information on environment event and trends (e.g. paleoclimate).

palma ratio

The share of all income received by the 10% people with highest disposable income divided by the share of all income received by the 40% people with the lowest disposable income (OECD, 2018b).

parasite

An organism that lives on or within another organism of a different species (the host) from which it obtains nourishment and to which it causes harm.

paris agreement

Agreement within the United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse gas emissions mitigation, adaptation and finance starting in the year 2020.

participatory governance

A variant or subset of governance which puts emphasis on democratic engagement, in particular through deliberative practices.

participatory mapping

A key method that many indigenous communities apply in order to collect data, information and monitoring and to use it in science- policy- society interface processes.

participatory methods

Participatory research methods are a variety of qualitative and quantitative methods geared towards planning and conducting the research process with those people whose life-world and meaningful actions are under study (Bergold & Thomas, 2012). Participatory methods acknowledge the possibility, the significance, and the usefulness of involving research partners in the knowledge-production process (Bergold, 2007).

participatory methods_2

Participatory research methods are a variety of qualitative and quantitative methods geared towards planning and conducting the research process with those people whose life-world and meaningful actions are under study (Bergold & Thomas, 2012). Participatory methods acknowledge the possibility, the significance, and the usefulness of involving research partners in the knowledge- production process.

participatory process

Specific methods employed to achieve active participation by all members of a group in a decision-making process (Chatty et al., 2003).

participatory process_2

Specific methods employed to achieve active participation by all members of a group in a decision-making process.

participatory scenario development (and planning)_1

Approaches characterised by more interactive, and inclusive, involvement of stakeholders in the formulation and evaluation of scenarios. Aimed at improving the transparency and relevance of decision-making, by incorporating demands and information of each stakeholder, and negotiating outcomes between stakeholders.

participatory scenario development (and planning)_2

Approaches characterized by more interactive, and inclusive, involvement of stakeholders in the formulation and evaluation of scenarios. Aimed at improving the transparency and relevance of decision-making, by incorporating demands and information of each stakeholder, and negotiating outcomes between stakeholders.

participatory scenario development (and planning)_3

Approaches characterised by more interactive, and inclusive, involvement of stakeholders in the formulation and evaluation of scenarios. Aimed at improving the transparency and relevance of decision making, by incorporating demands and information of each stakeholder, and negotiating outcomes between stakeholders.

particulate and gaseous pollutants

Air pollutants such as ozone, nitrogen oxides and ammonia.

particulate matter (pm)

A mixture of solid particles and liquid droplets (dust, dirt, soot, or smoke) (US Environmental Protection Agency, 2018b).

particulate matter_1

A mixture of solid particles (dust, dirt, soot, or smoke) and liquid droplets.

particulate matter_2

Particulate matter (PM), also known as atmospheric particulate matter, or suspended particulate matter (SPM) are microscopic solid or liquid matter suspended in Earth's atmosphere. Sources of particulate matter can be natural or anthropogenic. They have impacts on climate and precipitation that adversely affect human health.

particulate matter_3

A mixture of solid particles and liquid droplets (dust, dirt, soot, or smoke).

particulate organic carbon (poc)

The carbon content of particulate organic matter (Fiedler et al., 2008).

particulate organic matter

The large fraction (usually more than 7 micrometers) of soil organic matter (Fiedler et al., 2008).

passive restoration

See restoration.

pastoralism

Extensive livestock production in rangelands.

pathways

In the context of the IPBES global assessment, trajectories toward the achievement of goals and targets for biodiversity conservation and management of nature and nature’s contributions to people.

pathways3

In the context of the IPBES global assessment, trajectories toward the achievement of goals and targets for biodiversity conservation, the management of nature and nature’s contributions to people, and, more broadly, the UN 2030 Sustainable Development Goals.

pathways_3

“Pathways” consist of descriptions of different strategies for moving from the current situation towards a desired future vision or set of specified targets. They are descriptions of purposive courses of actions that build on each other, from short-term to long-term actions into broader transformation. They are closely related to normative or policy or target-seeking scenarios.

patrimonial species

A rare or threatened species which needs local management and which may be a flagship species and may have cultural importance (Pervanchon, 2004).

payment for ecosystem services (pes)

Payments for Ecosystem Services (PES) are a specific class of approach, used to facilitate voluntary transaction between a provider and a user of a service, conditioned on natural resource management rules for dealing with environmental externalities. PES is created to deal with market failures, environmental externalities, property rights problems and asymmetric information between economic actors.

payment for ecosystem services (pes)_1

Voluntary transactions that generate offsite services and are established to enable service users to pay resource providers for the conditional provision of the desired ecosystem service.

payment for ecosystem services (pes)_2

A payment mechanism that involves a series of payments to land or other natural resource owners in return for a guaranteed flow of ecosystem services or certain actions likely to enhance their provision over-and-above what would otherwise be provided in the absence of payment.

payments for ecosystem services (pes)_1

Payments for ecosystem services (PES) is a term used to describe a process whereas a beneficiary or user of an ecosystem service makes a direct or indirect payment to a provider of that service. PES involve a series of payments to land or other natural resource owners in return for a guaranteed flow of ecosystem services or certain actions likely to enhance their provision over-¬and-above what would otherwise be provided in the absence of payment.
