great acceleration

Great Acceleration refers to the acceleration of human-induced changes of the second half of the 20th century, unique in the history of human existence. Many human activities reached take-off points and sharply accelerated towards the end of the century.

Global assessment (1st work programme)
green bonds

A mode of private financing that tap the debt capital market through fixed income instruments (i.e. bonds) to raise capital to finance climate-friendly projects in key sectors of, but not limited to, transport, energy, building and industry, water, agriculture and forestry and waste.

green growth

Green growth means fostering economic growth and development while ensuring that natural assets continue to provide the resources and environmental services on which our well-being relies.

Global assessment (1st work programme)
green hunting

Green hunting occurs with tranquilizer dart guns and the animals are released alive. This is typically performed for veterinary procedures or translocation, and has been suggested as an alternative to lethal forms of hunting.

Sustainable use assessment
green infrastructure

Green infrastructure refers to the natural or semi-natural systems (e.g. riparian vegetation) that provide services for water resources management with equivalent or similar benefits to conventional (built) “grey” infrastructure (e.g. water treatment plants).

Global assessment (1st work programme)
green public procurement

A process whereby public authorities seek to procure goods, services and works with a reduced environmental impact throughout their life-cycle when compared to goods, services and works with the same primary function that would otherwise be procured.

Asia-Pacific assessment
green revolution

Period of food crop productivity growth that started in the 1960s due to a combination of high rates of investment in crop research, infrastructure, and market development and appropriate policy support, and whose environmental impacts have been mixed: on one side saving land conversion to agriculture, on the other side promoting an overuse of inputs and cultivation on areas otherwise improper to high levels of intensification, such as slopes.

Sustainable use assessment
green revolution

A set of research and the development of technology transfer initiatives occurring between the 1930s and the late 1960s (with prequels in the work of the agrarian geneticist Nazareno Strampelli in the 1920s and 1930s), that increased agricultural production worldwide, particularly in the developing world, beginning most markedly in the late 1960s. The initiatives resulted in the adoption of new technologies, including: new, high- yielding varieties (HYVs) of cereals, especially dwarf wheats and rices, in association with chemical fertilizers and agro-chemicals, and with controlled water-supply (usually involving irrigation) and new methods of cultivation, including mechanization. All of these together were seen as a package of practices to supersede traditional technology and to be adopted as a whole.

Land degradation and restoration assessment
greenhouse gas

Those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth’s surface, the atmosphere, and clouds. This property causes the greenhouse effect.

Land degradation and restoration assessment
greenhouse gas

Greenhouse gases are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of terrestrial radiation emitted by the Earth’s surface, the atmosphere itself, and by clouds. This property causes the greenhouse effect. Water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3) are the primary greenhouse gases in the Earth’s atmosphere. Moreover, there are a number of entirely human-made greenhouse gases in the atmosphere, such as the halocarbons and other chlorine- and brominecontaining substances, dealt with under the Montreal Protocol. Beside CO2, N2O and CH4, the Kyoto Protocol deals with the greenhouse gases sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs).

The amount of carbon fixed by the autotrophs (e.g. plants and algaes).

Global assessment (1st work programme)
paired catchment

Paired catchment studies have been widely used to assess the likely impact of land use change on water yield around the world. Such studies involve the use of two catchments (drainage basins) with similar characteristics in terms of slope, aspect, soils, area, precipitation and vegetation located adjacent to each other. Following a calibration period, where both catchments are monitored, one of the catchments is subjected to treatment and the other remains as a control. This allows the climatic variability to be accounted for in the analysis. The change in water yield can then be attributed to changes in vegetation. The paired catchment studies reported in the literature can be divided into four broad categories: (i) afforestation experiments; (ii) regrowth experiments; (iii) deforestation experiments; and (iv) forest conversion experiments.

Participatory research methods are a variety of qualitative and quantitative methods geared towards planning and conducting the research process with those people whose life-world and meaningful actions are under study (Bergold & Thomas, 2012). Participatory methods acknowledge the possibility, the significance, and the usefulness of involving research partners in the knowledge-production process (Bergold, 2007).

They are descriptions of purposive courses of actions that build on each other, from short-term to long-term actions into broader transformation. They are closely related to normative or policy or target-seeking scenarios.

Global assessment (1st work programme)
payment for ecosystem services

Payments for Ecosystem Services (PES) are a specific class of approach, used to facilitate voluntary transaction between a provider and a user of a service, conditioned on natural resource management rules for dealing with environmental externalities. PES is created to deal with market failures, environmental externalities, property rights problems and asymmetric information between economic actors.

Sustainable use assessment
payment for ecosystem services

Voluntary transactions that generate offsite services and are established to enable service users to pay resource providers for the conditional provision of the desired ecosystem service.

Americas assessment
payment for ecosystem services

A payment mechanism that involves a series of payments to land or other natural resource owners in return for a guaranteed flow of ecosystem services or certain actions likely to enhance their provision over-and-above what would otherwise be provided in the absence of payment.

payment for ecosystem services

Payments for ecosystem services (PES) is a term used to describe a process whereas a beneficiary or user of an ecosystem service makes a direct or indirect payment to a provider of that service. PES involve a series of payments to land or other natural resource owners in return for a guaranteed flow of ecosystem services or certain actions likely to enhance their provision over-¬and-above what would otherwise be provided in the absence of payment.
