Concept Definition Deliverable(s)
non-lethal harvest

Non-lethal harvest is defined as the temporary or permanent capture of live animals from their habitat without mortality, such as for the aquarium trade, pet trade or zoos, tag and release activities. Non-lethal harvest of animals also includes the parts or products of animals that do not lead to the mortality of the host, such as vicuna fiber, swift nests or wild honey.

Sustainable use assessment
non-linear

Not arranged in a straight line, not sequential or straightforward.

Asia-Pacific assessment
non-monetary valuation

The value attributable to an item or a service without relation to any acceptable cash price and for which a fixed or determinable amount of currency is absent (e.g. many ecosystem services, interpersonal good-will, health, etc.).

Pollination assessment
non-timber forest product

Non-timber forest products (NTFPs) are useful substances, materials and/or commodities obtained from forests which do not require harvesting (logging) trees. They include game animals, fur-bearers, nuts, seeds, berries, mushrooms, oils, foliage, pollarding, medicinal plants, peat, mast, fuelwood, fish, spices and forage.

Asia-Pacific assessment
non-timber forest product

Any biological resources found in forests other than timber, including fuel wood and small wood, nuts, seeds, oils, foliage, game animals, berries, medicinal plants, fish, spices, barks, and mushrooms, among others (Prasad, 1993).

normative scenarios

see target- seeking scenarios.

Scenarios and models assessment
norms

Norms are rules about what is accepted behaviour. They are supporting underlying values as defined by a society. They are therefore ‘ought to’ statements defining what one may or may not do. Examples are rules about care for nature and what is just treatment of others.

Values assessment

Sustainable use assessment, Global assessment (1st work programme)
radiative forcing

The measurement of the capacity of a gas or other forcing agents to affect that energy balance, thereby contributing to climate change. Put more simply, RF expresses the change in energy in the atmosphere due to GHG emissions.

The preservation of land with the goal of restoring natural ecosystem processes and reducing human control of landscapes (Gillson et al., 2011) to allow declining populations to rebound.

Global assessment (1st work programme)
reactive nitrogen

All biologically, photochemically, and/or radiatively active forms of nitrogen; a diverse pool of nitrogenous compounds that includes organic compounds (e.g. urea, amines, proteins, amides), mineral nitrogen forms, such as nitrates and ammonium, as well as gases that are chemically active in the troposphere (NOx, ammonia, nitrous oxide) and contribute to air pollution and the greenhouse effect.

rebound effect

The pattern by which resource users tend to compensate for improved efficiency by shifting behaviour towards greater consumption, which undermines apparent gains. For example, an increased fuel saving of motor vehicle tends to be compensated by spending more money on other resources or by driving more.

Sustainable use assessment
reducing emissions from deforestation and forest degradation

A global mechanism designed to offer positive incentives to reduce emissions from deforestation and forest degradation, and to promote the conservation, management and enhancement of forest stocks in developing countries (http://theredddesk. org/encyclopaedia/reducing-emissions- deforestation-and-forest-degradation-redd- and-role-conservation). REDD-plus stands for countries’ efforts to reduce emissions from deforestation and forest degradation, and foster conservation, sustainable management of forests, and enhancement of forest carbon stocks.

Asia-Pacific assessment
reducing emissions from deforestation and forest degradation

Mechanism developed by Parties to the United Nations Framework Convention on Climate Change (UNFCCC), which creates a financial value for the carbon stored in forests by offering incentives for developing countries to reduce emissions from forested lands.

reducing emissions from deforestation and forest degradation

Reducing emissions from deforestation and forest degradation (REDD+) is a mechanism developed by Parties to the United Nations Framework Convention on Climate Change (UNFCCC). It creates a financial value for the carbon stored in forests by offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. Developing countries would receive results-based payments for results- based actions. REDD+ goes beyond simply deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks.
