Concept Definition Deliverable(s)
opportunity cost

The foregone benefits of carrying out one activity in favor of another, or giving up their initial preferred land-use plan.

Americas assessment
option value

The potential ability to use some of nature’s benefits in the future, although they are not currently used, or the likelihood for their future use is low. It represents the willingness to preserve an option for the future enjoyment of nature’s benefits.

Scenarios and models assessment
organic agriculture

Any system that emphasizes the use of techniques such as crop rotation, compost or manure application, and biological pest control in preference to synthetic inputs. Most certified organic farming schemes prohibit all genetically modified organisms and almost all synthetic inputs. Its origins are in a holistic management system that avoids off-farm inputs, but some organic agriculture now uses relatively high levels of off-farm inputs.

organic farming

Crop and livestock production using natural sources of nutrients (such as compost, crop residues, and manure) and natural methods of crop and weed control, instead of using synthetic or inorganic agrochemicals. Genetically modified organisms are not usually part of organic agriculture. It is also sometimes called low- input farming, but may involve high inputs of labour and be intensive in its practice.

Pollination assessment
other effective area-based conservation measures

A geographically defined area other than a protected area, which is governed and managed in ways that achieve positive and sustained long- term outcomes for the in situ conservation of biodiversity (CBD, 2018a).

Global assessment (1st work programme)
overexploitation

Overexploitation means harvesting species from the wild at rates faster than natural populations can recover. Includes overfishing, and overgrazing.

Asia-Pacific assessment, Sustainable use assessment
overexploitation

Harvesting species from the wild at rates faster than natural populations can recover. Includes overfishing, and overgrazing.

Africa assessment, Europe and Central Asia assessment, Americas assessment, Global assessment (1st work programme)
overgrazing

Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals.

Asia-Pacific assessment, Sustainable use assessment
overgrazing

An excess of herbivory that leads to degradation of plant and soil resources.

Americas assessment
overstocking

Placing a number of animals on a given area that will result in overuse if continued to the end of the planned grazing period.

Land degradation and restoration assessment
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.

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.
