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.

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.
