Concept Definition Deliverable(s)
classical biological control

the intentional introduction of an alien species, usually co-evolved, as a biological control agent for permanent establishment and long-term control

Invasive alien species assessment
clean development mechanism

Defined in Article 12 of the Protocol, allows a country with an emission-reduction or emission-limitation commitment under the Kyoto Protocol (Annex B Party) to implement an emission-reduction project in developing countries. Such projects can earn saleable certified emission reduction (CER) credits, each equivalent to one tone of CO2, which can be counted towards meeting Kyoto targets.

Land degradation and restoration assessment
climate

Climate is the average weather, or more rigorously, its statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years. The classical period for averaging these variables is 30 years, as defined by the World Meteorological Organization. The relevant quantities are most often surface variables such as temperature, precipitation and wind. Climate in a wider sense is the state, including a statistical description, of the climate system. In the ocean, climate change is manifested as altered hydrologic conditions including temperature, oxygen, sea level, the carbonate system, and related changes in productivity, mixing and circulation.

climate change

As defined in Article 1 of the United Nations Framework Convention on Climate Change, a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

Sustainable use assessment
climate change adaptation

Adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities.

Land degradation and restoration assessment
climate change mitigation

A set of actions to limit the magnitude or rate of long-term climate change. Climate change mitigation generally involves reductions in human (anthropogenic) emissions of greenhouse gases (GHGs). Mitigation may also be achieved by increasing the capacity of carbon sinks, e.g. through reforestation. Mitigation policies can substantially reduce the risks associated with human-induced global warming.

Land degradation and restoration assessment
climate change

Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e. decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer- term average conditions. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have been identified as primary causes of ongoing climate change, often referred to as global warming.

Asia-Pacific assessment
climate change

Refers to a change of climate that is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and that is in addition to natural climate variability observed over comparable time periods.

Land degradation and restoration assessment
climate change

As defined in Article 1 of the UNFCCC, a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

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

A change in the state of the climate that can be identified (e.g. by using statistical tests) by changes in the mean and/or the variability of its properties and that persists for an extended period, typically decades or longer. Climate change may be due to natural internal processes or external forcings such as modulations of the solar cycles, volcanic eruptions and persistent anthropogenic changes in the composition of the atmosphere or in land use. Note that the United Nations Framework Convention on Climate Change (UNFCCC), in its Article 1, defines climate change as: ‘a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods’. The UNFCCC thus makes a distinction between climate change attributable to human activities altering the atmospheric composition and climate variability attributable to natural causes.

Land degradation and restoration assessment
common pool resource

Resources for which the exclusion of users is difficult (referred to as excludability), and the use of such a resource by one user decreases resource benefits for other users (referred to as subtractability). Common CPR examples include fisheries, forests, irrigation systems, and pastures. Global CPR examples include the earth’s oceans and atmosphere. Difficulty in excluding users, combined with a CPR’s subtractability, create management vulnerabilities that can result in resource degradation, often referred to as the tragedy of the commons. See also Tragedy of commons” and Commons”.

Land degradation and restoration assessment
common property theory

Common property theory (CPT) refers to a body of cross-disciplinary literature that deals with the historical and contemporary institutional governance and management of valued resources ranging from fisheries and forests to atmospheric sinks, oceans, and genetic materials. CPT was originally developed to understand the problems of managing what are termed common-pool resources.

Sustainable use assessment
commons

A concept whereby some forms of wealth belong to all, and that these community resources must be actively protected and managed for the good of all. It consists of land and services of common property (forests, rivers, fields and arable land) used and managed by a given community (mainly traditional, local or indigenous). The commons also consist of gifts of nature such as air, oceans and wildlife (global commons) as well as shared social creations such as libraries, public spaces, scientific research and creative works. See also Common Pool Resources” and Tragedy of the commons”.
