Glossary of terms related to the CBD


impact assessment
an evaluation of the likely impact on biological diversity of proposed programmes, policies, or projects. [CUB]
a cross between parents of similar genetic constitution which could be from the same blood line (shared ancestry). [CUB]
in-bred line
in plants, a line produced by repeated selfing and selection. Results in truebreeding and a fixed genotype. [CUB]
- mating among related individuals.
- mating of close relatives, which reduces genetic diversity, often leading to expression of deleterious recessive characteristics and reduction of fitness in the offspring.
inbreeding depression
a reduction in fitness and vigour of individuals as a result of increased homozygosity through inbreeding in a normally outbreeding population.
flow of money, goods or services deriving from the productive use of assets.
indicator species
a species whose status provides information on the overall condition of the ecosystem and of other species in that ecosystem. They reflect the quality and changes in environmental conditions as well as aspects of community composition. [GBA]
indigenous peoples
people whose ancestors inhabited a place or country when persons from another culture or ethnic background arrived on the scene and dominated them through conquest, settlement, or other means and who today live more in conformity with their own social, economic, and cultural customs and traditions than with those of the country of which they now form a part. (Also: "native peoples" or "tribal peoples".) [GBA]
informal contact group
on the instructions of the President or Chair, delegates may meet in private to discuss specific matters in order to consolidate different views, reach a compromise, and produce an agreed proposal, often in the form of written text.
in the original location. (Opposite: ex-situ)
in-situ conditions
conditions where genetic resources exist within ecosystems and natural habitats, and, in the case of domesticated or cultivated species, in the surroundings where they have developed their distinctive properties. [CBD]
- the conservation of ecosystems and natural habitats and the maintenance and recovery of viable populations of species in their natural surroundings and, in the case of domesticated or cultivated species, in the surroundings where they have developed their distinctive properties. [CBD]
- the conservation of biodiversity within the evolutionary dynamic ecosystems of the original habitat or natural environment. [GBA]
in situ conservation of farm animal genetic diversity
all measures to maintain live animal breeding populations, including those involved in active breeding programmes in the agro-ecosystem where they either developed or are now normally found, together with husbandry activities that are undertaken to ensure the continued contribution of these resources to sustainable food and agricultural production, now and in the future. [FAO]
in-situ gene banks
protected areas designated specifically to protect genetic variability of particular species. [GBA]
insurance value
the value of biodiversity in maintaining ecosystem functions over a range of environmental conditions. [GBA]
integrated area management  (IAM)
management approach whereby a specific area is zoned and regulated for a variety of uses, including research, species protection, tourism, harvesting, cutting down trees, hunting, or fishing, that is compatible with the management goals for the area.
integrated pest management
- an ecologically based strategy that relies on natural mortality factors, such as natural enemies, weather, and crop management, and seeks to control tactics that disrupt these factors as little as possible while enhancing their effectiveness. [GBA]
- the challenging or control of pests through a tailored programme of different strategies including biological control agents and agrochemicals. [CUB]
intellectual property right
a right enabling an inventor to exclude imitators from the market for a limited time.
intergenerational equity
a core proposition is that future generations have a right to an inheritance (capital bequest) sufficient to allow them to generate a level of well-being no less than that of the current generation. Fairness in the treatment of different members of the same generation. [GBA]
intertidal zone
the zone of overlap between land and sea that is submerged at high tide and exposed at low tide.
introduced species
see: alien species.
the entry of a pest [or species] resulting in its establishment. [FAO bis]
introduction of a biological control agent
the release of a biological control agent into an ecosystem or an area where it did not exist previously. [FAO bis]
inundative release
the release of overwhelming numbers of a mass-produced biological control agent in the expectation of achieving a rapid reduction of a pest population without necessarily achieving continuing impact. [FAO bis]
incorporation of genes of one species into a gene pool of another species.
invasive species
an introduced species which invades natural habitats.
the surveying, sorting, cataloguing, quantifying and mapping of entities such as genes, individuals, populations, species, habitats, ecosystems and landscapes or their components, and the synthesis of the resulting information for the analysis of process. [GBA]
any animal without backbone or spinal column.
in vitro
- storage of living materials as tissue culture, and may include cryopreservation (storage at low temperature, usually in liquid nitrogen).
- literally 'in glass'. Experimental reproduction of biological processes in isolation from a living organism, e.g. tissue culture. [CUB]
in vitro culture
see: tissue culture.
in vivo
taking place in a living organism.
