Concept Definition Deliverable(s)
brackish water

Water that has more salinity than fresh water, but not as much as seawater. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers. Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gravity of between 1.005 and 1.010. Thus, brackish covers a range of salinity regimes and is not considered a precisely defined condition.

Asia-Pacific assessment
breadth

refers to change across multiple spheres, with emerging consensus that transformation requires co-evolutionary change across different spheres of society, including personal, economic, political, institutional and technological ones.

Values assessment
bridging organizations

offer a means to improve environmental management outcomes by spanning the science-policy interface to allow for the effective sharing of data, information, and knowledge. Bridging organizations are institutions that use specific mechanisms such as working groups to link and facilitate interactions among individual actors in a management setting.

Invasive alien species assessment
broad values

They refer to life goals, general guiding principles and orientations towards the world that are informed by people’s beliefs and worldviews. Broad values include moral principles, such as justice, belonging, freedom, but also life goals, like enjoyment, health, prosperity. Broad values influence specific values and provide them with a general context and meaning.

Values assessment
buen vivir

Although no universal definition of buen vivir has been attained yet, it has four common constitutive elements: (a) the idea of harmony with nature (including its abiotic components); (b) vindication of the principles and values of marginalized/subordinated peoples; (c) the State as guarantor of the satisfaction of basic needs (such as education, health, food and water), social justice and equality; and (d) democracy. There are also two cross-cutting lines: buen vivir as a critical paradigm of Eurocentric (anthropocentric, capitalist, economistic and universalistic) modernity, and as a new intercultural political project.

Global assessment (1st work programme), Americas assessment
buen vivir

An alternative to economic development-centered approaches, generally defined as forming part of the Andean indigenous cosmology, based on the belief that true wellbeing is only possible as part of a community in a broad sense, including people, nature and the Earth, linked by mutual responsibilities and obligations, and that the wellbeing of the community is above that of the individual.

buffer (ecology)

Programmes designed to accredit goods and services that meet defined process standards designed to improve environmental performance and, in some cases, also to improve social welfare in places of production.

ecological disturbance (natural and anthropogenic)

An event that can disrupt any ecological level, environmental component as well as the organizational status of a biological cycle of organisms. Disturbances are an important aspect in the natural selection and the whole biological evolution, as they modify the environment in which every living being performs its vital functions.

Global assessment (1st work programme)
ecological footprint

Ecological footprint has a variety of definitions, but is defined by the Global Footprint Network the as a measure of how much area of biologically productive land and water an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates, using prevailing technology and resource management practices. The ecological footprint indicator used in this report is based on the Global Footprint Network unless otherwise specified.[ [0[

Asia-Pacific assessment, Global assessment (1st work programme)
ecological footprint

A measure of the amount of biologically productive land and water required to support the demands of a population or productive activity. Ecological footprints can be calculated at any scale: for an activity, a person, a community, a city, a region, a nation or humanity as a whole.

Global assessment (1st work programme)
ecological infrastructure

Ecological infrastructure refers to the natural or semi-natural structural elements of ecosystems and landscapes that are important in delivering ecosystem services. It is similar to ‘green infrastructure', a term sometimes applied in a more urban context. The ecological infrastructure needed to support pollinators and improve pollination services includes patches of semi-natural habitats, including hedgerows, grassland and forest, distributed throughout productive agricultural landscapes, providing nesting and floral resources. Larger areas of natural habitat are also ecological infrastructure, although these do not directly support agricultural pollination in areas more than a few kilometers away from pollinator- dependent crops.

Americas assessment
ecological infrastructure

Ecological infrastructure refers to the natural or semi-natural structural elements of ecosystems and landscapes that are important in delivering ecosystem services. It is similar to ‘green infrastructure', or ‘green and blue infrastructure' a term sometimes applied in a more urban context. The ecological infrastructure needed to support pollinators and improve pollination services includes patches of semi-natural habitats, including hedgerows, grassland and forest, distributed throughout productive agricultural landscapes, providing nesting and floral resources. Larger areas of natural habitat are also ecological infrastructure, although these do not directly support agricultural pollination in areas more than a few kilometers away from pollinator-dependent crops.

The take-over of local natural resources by private and/or state interests, and the gradual or immediate disorganization of the ecosystem via withdrawals and additions.

Land degradation and restoration assessment
ecological processes

The physical and biological actions or events that link organisms and their environment.

Asia-Pacific assessment
ecological solidarity

As explained by Thompson et al. (2011): From ecology based on interactions to solidarity based on links between individuals united around a common goal and conscious of their common interests and their moral obligation and responsibility to help others, we define ecological solidarity as the reciprocal interdependence of living organisms amongst each other and with spatial and temporal variation in their physical environment.

Land degradation and restoration assessment
ecologically intensified agriculture

Any system that maintains efficient production by optimal management of naturally occurring ecological functions and biodiversity. To be put in place, understandings are required of the relations between land use at different scales and the community composition of ecosystem service-providing organisms above- and below-ground, and the flow, stability, contribution to yield, and management costs of the multiple services delivered by these organisms.
