Glossary of terms related to the CBD


national delegation
one or more officials who are empowered to represent and negotiate on behalf of their government
national income accounts
system of record by which the vigor of a nation's economy is measured. (Results are often listed as Gross National Product, or Gross Domestic Product.)
native peoples
see: indigenous peoples.
native species
plants, animals, fungi, and micro-organisms that occur naturally in a given area or region.
natural enemy
an organism which lives at the expense of another organism and which may help to limit the population of its host. This includes parasitoids, parasites, predators and pathogens [FAO bis].
natural forest
see: primary forest.
natural forest management system
controlled and regulated harvesting of forest trees, combined with silvicultural and protective measures, to sustain and increase the commercial value of subsequent stands; relies on natural regeneration of native species. [GBA]
natural selection
process by which the genotypes in a population that are best adapted to the environment increase in frequency relative to less well-adapted genotypes over a number of generations.
swimming organisms that are able to move independently of water currents (opp. plankton). These include most fish, mammals, turtles, sea snakes, and aquatic birds.
roundworms, often internal parasites of animals and plants. The latter are significant economic pests on foodcrops as few crops are immune to attacks of these creatures which inhabit the soil about the roots of plants. The development of nematode-resistant varieties of crop plants is important to food growth economics. [CUB, modified by JVG]
clusters of closely related species and subspecies that have evolved relatively recently.
net present value
the discounted value of the net benefits of use of a resource.
the place occupied by a species in its ecosystem and its role: where it lives, what it feeds on and when it performs all its activities.
nitrogen fixation
biological assimilation of atmospheric nitrogen to form organic nitrogen-containing compounds.
non-consumptive value
the value of resources which are not diminished by their use. Values that do not require access to or active use of a biological resource by the valuer. Passive use value may imply that the resource is used by other humans whose welfare matters to the valuer. It therefore includes vicarious use value, bequest value and existence value. (Also non-use or passive use value.) [GBA]
non-equilibrium theory
suggests that the number of species increases or decreases depending on how the environment influences species production, exchange and extinction at any particular time.
non-exclusive goods
public goods to which it is impossible, or excessively costly, to operate any mechanism.
non-governmental organization (NGO)
a non-profit group or association organized outside of institutionalized political structures to realize particular social objectives (such as environmental protection) or serve particular constituencies (such as indigenous peoples). NGO activities range from research, information distribution, training, local organization, and community service to legal advocacy, lobbying for legislative change, and civil disobedience. NGO's range in size from small groups within a particular community to huge membership groups with a national or international scope. [UNEP]
Many relevant NGOs attend the biodiversity meetings as observers in order to interact with delegates and press and provide information. NGOs must be non-profit and can include environmental groups, research institutions, business groups, and associations of urban and local governments.
in-session document issued informally to facilitate negotiations; it does not have an official document symbol although they may have an identifying number or the name of the author(s).
a state that has not ratified the Convention and may attend meetings as an observer.
non-use value
see: non-consumptive value.
normalizing selection
see: stabilizing selection.
unit building block of DNA. It consists of a sugar and phosphate backbone with a base attached.
null model
the model of no effect.
