IPBES core glossary

Type of ecosystem characterized by a more or less closed herbaceous (non-woody) vegetation layer, sometimes with a shrub layer, but - in contrast to savannas - without, or with very few, trees. Different types of grasslands are found under a broad range of climatic conditions.

Feeding on growing herbage, attached algae, or phytoplankton.

The strategies used by people to promote both high quality and quantity of forage for domesticated livestock.

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.

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 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.

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.

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).

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.

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.

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.

Water transpired through plants to the atmosphere.

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.

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).

Any wastewater that is not contaminated with faecal matter.

Total terrestrial Gross Primary Production (GPP) is the total mass of carbon taken out of the atmosphere by plant photosynthesis.

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

The place or type of site where an organism or population naturally occurs. Also used to mean the environmental attributes required by a particular species or its ecological niche.

The degree to which the landscape facilitates the movement of organisms (animals, plant reproductive structures, pollen, pollinators, spores, etc.) and other environmentally important resources (e.g. nutrients and moisture) between similar habitats. Connectivity is hampered by fragmentation (q.v.).

A general term describing the set of processes by which habitat quality is reduced. Habitat degradation may occur through natural processes (e.g. drought, heat, cold) and through human activities (forestry, agriculture, urbanization).

The ability of soil or soil materials to serve as a habitat for micro-organisms, plants, soil- living animals and their interactions.

A general term describing the set of processes by which habitat loss results in the division of continuous habitats into a greater number of smaller patches of lesser total and isolated from each other by a matrix of dissimilar habitats. Habitat fragmentation may occur through natural processes (e.g. forest and grassland fires, flooding) and through human activities (forestry, agriculture, urbanization).

The number of different habitats in a landscape.

A general term describing the set of processes by which habitat quality is reduced. Habitat degradation may occur through natural processes (e.g. drought, heat, cold) and through human activities (forestry, agriculture, urbanization).

Changes in an area's primary ecological functions and species composition due to human activity and/or non-native species invasion.

The importance of ecosystems to provide living space for resident and migratory species (thus maintaining the gene pool and nursery service).

Species that require very specific habitats and resources (e.g. narrow range of food sources or cover types) to thrive and reproduce.

The place or type of site where an organism or population naturally occurs.

They occur when colonies of algae (simple plants that live in the sea and freshwater) grow out of control and produce toxic or harmful effects on people, fish, shellfish, marine mammals and birds.

Harmful algal blooms (HABs) occur when colonies of algae grow out of control and produce toxic or harmful effects on people, fish, shellfish, marine mammals and birds. The human illnesses caused by HABs, though rare, can be debilitating or even fatal.

The process of bringing together, and comparing, models or scenarios to make them compatible or consistent with one another.

The process of bringing something together, and comparing (e.g. models or scenarios) to facilitate compatibility or consistency.

A process, phenomenon or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or environmental degradation. Hazards that this assessment discusses are mostly environmental hazards (chemical, natural and biological hazards), while cognizant that many hazards are socio- natural, in that they are associated with a combination of natural and anthropogenic factors. Natural hazards are predominantly associated with natural processes and phenomena, including geological or geophysical hazards that originate from internal earth processes (earthquakes, volcanic activities, landslides, tsunamis), and hydrometeorological hazards, which are of atmospheric, hydrological or oceanographic origin (tropical cyclones, floods, drought; heatwaves, and storm surges). Biological hazards are of organic origin or conveyed by biological vectors, including pathogenic microorganisms, toxins and bioactive substances. Examples are bacteria, viruses or parasites, as well as venomous wildlife and insects, poisonous plants and mosquitoes carrying disease-causing agents.

Describes built up areas that are hotter than nearby rural areas. Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water quality.
