The volume of freshwater used to produce the commodity, good or service, measured at the place where the product was actually produced.

Land degradation and restoration assessment
virtual water balance

In global trade, the difference between water used to produce export products and the water used to produce import products.

vision

A desirable future (an endpoint in time) which we want to achieve. Visions usually consist of statements depicting the explicit desires, assumptions, beliefs and paradigms that underlie the desired future.

Europe and Central Asia assessment
visions (of the future)

“Visions” are descriptions of a desirable future (an endpoint in time), which society or parts of society want to achieve. They usually consist of statements depicting orienting goals, and the assumptions, beliefs and paradigms that underlie the desired future. Visions can take the form of policy targets, but can also be formulated by a range of actors, e.g. from the private sector to address business targets or civil society to address social targets.

Values assessment
volatilization

The process of converting a chemical substance from a liquid or solid state to a gaseous or vapour state.

Global assessment (1st work programme)
western culture

(Also called modern science, Western scientific knowledge or international science) is used in the context of the IPBES conceptual framework as a broad term to refer to knowledge typically generated in universities, research institutions and private firms following paradigms and methods typically associated with the scientific method consolidated in Post-Renaissance Europe on the basis of wider and more ancient roots. It is typically transmitted through scientific journals and scholarly books. Some of its central tenets are observer independence, replicable findings, systematic scepticism, and transparent research methodologies with standard units and categories.

wetland

Areas that are subject to inundation or soil saturation at a frequency and duration, such that the plant communities present are dominated by species adapted to growing in saturated soil conditions, and/or that the soils of the area are chemically and physically modified due to saturation and indicate a lack of oxygen; such areas are frequently termed peatlands, marshes, swamps, sloughs, fens, bogs, wet meadows, etc.

widespread species

species that are able to maintain viable populations across a range of environments leading to a large range size. Widespread species are likely to experience a large range of ecological and climatic conditions within their range. A large niche width – based on the current distribution of a species – seems to be a general pattern in widespread species

wild pollinator

A pollinator that can live without human husbandry. Some may depend on agricultural settings for survival.

Pollination assessment
wild relative

Wild species related to crops, including crop progenitors.

Global assessment (1st work programme), Sustainable use assessment
wild species

Wild species refers to populations of any species that have not been domesticated through multigenerational selection for particular traits, and which can survive independently of human intervention that may occur in any environment. This does not imply a complete absence of human management and recognizes various intermediate states between wild and domesticated. This assessment excludes feral and introduced populations.

Sustainable use assessment
wild species watching

Wild species watching is defined as a non-extractive practice where humans observe, and in some cases interact, with wild species in their natural environment in a way that does not involve the harvest or removal of any part of the organism. Wild species watching activities vary greatly in the level of wild species involvement, ranging from photographing animals from afar to more invasive practices of habituating, feeding and touching animals (UNEP/CMS, 2006, p. 2006). Wild species watching also is an economically important segment of nature-based tourism.
