- 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
- 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
- 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
- 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
- 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.
