Concept Definition Deliverable(s)
intellectual property rights

Intellectual property rights are the rights given to persons over the creations of their minds. They usually give the creator an exclusive right over the use of his/her creation for a certain period of time. Intellectual property rights are customarily divided into two main areas: rights related to copyright, and industrial property.

Sustainable use assessment
intensive agriculture

Intensive agriculture involves various types of agriculture with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital and labor, and higher crop yields per unit land area.

Asia-Pacific assessment
intensive grazing land

Grazing lands that are managed primarily for livestock production with few other uses of the land other than dispersed crops.

Land degradation and restoration assessment
intensive grazing land

Those that are managed intensively for livestock production with few other uses of the land and cover approximately 9% of global grazing lands.

inter-generational equity

Inter-generational equity stipulates the rights and obligations of the current and future generations regarding the use of the environment. In the context of sustainable development, the Brundtland Report conceptualised it as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Sustainable use assessment
intrinsic value

The ethical or philosophical value that an object has, in and of itself. It is the actual value of an asset based on underlying perceptions of both tangible and intangible factors.

intrinsic value

The value inherent to nature, independent of human experience and evaluation, and therefore beyond the scope of anthropocentric valuation approaches.

Asia-Pacific assessment, Land degradation and restoration assessment, Europe and Central Asia assessment, Scenarios and models assessment
intrinsic value

This concept refers to inherent value, that is the value something has independent of any human experience or evaluation. Such a value is viewed as an inherent property of the entity and not ascribed or generated by external valuing agents.

introduced pollinator

A pollinator species living outside its native distributional range (see Exotic pollinator).

Pollination assessment
introduction pathway

a suite of processes that result in the introduction of a species from one geographical location to another. It means: 1) geographic routes by which a species is moved outside its natural range (past or present); 2) corridors of introduction (e.g., road, canal, tunnel); and/or 3) human activity that gives rise to an intentional or unintentional introduction. More than one vector (see definition of vector below) within a pathway may be involved in a transfer of species

Invasive alien species assessment
invasion cold spot

areas of low alien species richness relative to other regions with similar biogeographic characteristics (O’Donnell et al., 2012). Biodiversity hot spots of diversi?cation and species richness are defined as geographic regions with high diversi?cation rates or high species richness, respectively, while conversely cold spots are geographic regions with low diversi?cation rates or species richness

Invasive alien species assessment
invasion curve

depiction of the different stages of invasive alien species management from prevention to early detection and eradication, containment and adaptive management (Invasive Species Centre, 2021). The curve shows that eradication of an invasive alien species is less probable and more costly as it spreads over time. Choosing a management action relies on where a species is on the invasion curve.

Invasive alien species assessment
invasion debts

the potential increase in biological invasions at a site over a particular time frame in the absence of any interventions (Rouget et al., 2016). It is composed of the number of new species that will be introduced (introduction debt), the number of species that will become invasive (species-based invasion debt), the increase in area affected by invasions (area-based invasion debt), and the increase in the negative impacts caused by introduced species (impact-based invasion debt)

Invasive alien species assessment
invasion hotspot

areas of high alien species richness relative to other regions with similar biogeographic characteristics (O’Donnell et al., 2012). Biodiversity hot spots of diversi?cation and species richness are defined as geographic regions with high diversi?cation rates or high species richness, respectively, while conversely cold spots are geographic regions with low diversi?cation rates or species richness

Invasive alien species assessment
invasion stages

stages (transport, introduction, establishment, and spread) that a species must pass through on the invasion continuum from native to (invasive) alien species, recognising the need for a species to overcome the barriers (geography, captivity or cultivation, survival, reproduction, dispersal and environmental) that obstruct transition between each stage

Invasive alien species assessment
invasional meltdown

the amplification of impacts of invasive alien species through community-level processes in which there is a cascade of effects, positive feedback loops, arising from the interactions amongst species, in this case alien species, which ultimately affect ecosystem functions

Invasive alien species assessment
invasive alien species

A species introduced outside its natural past or present distribution whose introduction and/or spread threaten biological diversity.

Scenarios and models assessment
invasive alien species

Species whose introduction and/or spread by human action outside their natural distribution threatens biological diversity, food security, and human health and well-being. Alien refers to the species' having been introduced outside its natural distribution (exotic, non-native and non-indigenous are synonyms for alien). Invasive means tending to expand into and modify ecosystems to which it has been introduced. Thus, a species may be alien without being invasive, or, in the case of a species native to a region, it may increase and become invasive, without actually being an alien species.

invasive alien species

animals, plants or other organisms introduced directly or indirectly by people into places out of their natural range of distribution, where they have become established and dispersed, and generating an impact on local ecosystems and species (IPBES, 2016); see Chapter 1 for further discussion). Invasive alien species are a subset of established alien species that have negative impacts.

Invasive alien species assessment
invasive pollinator

A pollinator species that, once it has been introduced outside its native distributional range, has a tendency to spread without direct human assistance.

ipbes conceptual framework

The Platform's conceptual framework has been designed to build shared understanding across disciplines, knowledge systems and stakeholders of the interplay between biodiversity and ecosystem drivers, and of the role they play in building a good quality of life through nature's contributions to people.

Africa assessment, Americas assessment, Sustainable use assessment
ipbes conceptual framework

A simplified representation of the complex interactions between the natural world and human societies. This framework emerged from an extensive process of consultation and negotiation, leading to formal adoption by the second IPBES Plenary (IPBES/2/4), and therefore represents a key foundation for all IPBES activities. The framework recognizes different knowledge systems, including indigenous and local knowledge (ILK) systems, which can be complementary to those based on science.

IUCN habitats classification scheme

Classification Schemes (formerly referred to as Authority Files) are a set of standard terms developed for documenting taxa on the IUCN Red List in order to ensure global uniformity when describing the habitat in which a taxon occurs, the threats to a taxon, what conservation actions are in place or are needed, and whether or not the taxon is utilized.

IUCN protected area category

IUCN protected area management categories classify protected areas according to their management objectives.

IUCN red list

The IUCN Red List is an indicator of the health of biodiversity. It provides taxonomic, conservation status and distribution information on plants, fungi and animals that have been globally evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalogue and highlight those plants and animals that are facing a higher risk of global extinction.

Asia-Pacific assessment
IUCN red list

The IUCN Red List of Threatened Species provides taxonomic, conservation status and distribution information on taxa that have been globally evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalogue and highlight those taxa that are facing a higher risk of global extinction (i.e. as Critically Endangered, Endangered and Vulnerable). The IUCN Red List also includes information on taxa that are categorized as Extinct or Extinct in the Wild; on taxa that cannot be evaluated because of insufficient information (i.e. are Data Deficient); and on taxa that are either close to meeting the threatened thresholds or that would be threatened were it not for an ongoing taxon- specific conservation programme (i.e. are Near Threatened).
