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)

A natural or anthropogenic feature which separates land uses.

Sustainable use assessment, Global assessment (1st work programme)
bycatch

The commercially undesirable species caught during a fishing process.

Europe and Central Asia assessment, Americas assessment, Asia-Pacific assessment
gathering

Gathering is defined as the removal of terrestrial and aquatic algae, fungi, and plants (other than trees) or parts thereof from their habitats. Gathering may, but often does not, result in the death of the organism. Gathering includes whole plant harvest and removal of above and/or below ground plant parts, as well as the fruiting bodies of macrofungi. It also includes removal of non-woody portions of trees (leaves, propagules, and bark). Where removal of propagules or death of an individual plant occurs (e.g. whole plant and root removal) effects on population sustainability are contingent upon factors including timing, frequency, and intensity of harvest. The harvest of wood and woody parts of trees is encompassed by the definition of logging.

Sustainable use assessment
gender

The term gender refers to the socially-constructed expectations about the characteristics, aptitudes and behaviors associated with being a woman or a man. Gender defines what is feminine and masculine. Gender shapes the social roles that mean and women play and the power relations between them, which can have a profound effect on the use and management of natural resources. Gender is not based on sex or the biological differences between women and men; rather, gender is shaped by culture and social norms. Thus, depending on values, norms, customs and laws, women and men in different parts of the world have adopted different gender roles and relations. Within the same society, gender roles also differ by race/ethnicity, class/caste, religion, ethnicity, age and economic circumstances. Gender and gender roles then affect the economic, political, social, and ecological opportunities and constraints faced by both women and men (Convention on Biological Diversity, 2017). The framing of sex and gender as binaries is in fact a cultural ideology. The empirical reality is that sex is a spectrum, manifesting in a wide array of sex variance. Some people don't neatly fit into the categories of man or woman, or “male” or “female.” For example, some people have a gender that blends elements of being a man or a woman, or a gender that is different than either male or female. Some people don't identify with any gender, or their gender changes over time.

Sustainable use assessment
gene

The basic physical and functional unit of heredity. Genes are made up of DNA, and occupy a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins.

Global assessment (1st work programme), Sustainable use assessment
gene flow

The movement of individuals, and/or the genetic material they carry, from one population to another. Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries.

Global assessment (1st work programme)
general circulation model

A numerical representation of the physical processes in the atmosphere, ocean, cryosphere and land surface based on the physical, chemical and biological properties of their components, their interactions and feedback processes, and accounting for all or some of its known properties.

Land degradation and restoration assessment
generalist species

A species able to thrive in a wide variety of environmental conditions and that can make use of a variety of different resources (for example, a flower-visiting insect that lives on the floral resources provided by several to many different plants).

Americas assessment, Sustainable use assessment, Europe and Central Asia assessment
genetic composition

The composition in alleles of a population.

Global assessment (1st work programme)
genetic diversity

The variation at the level of individual genes, which provides a mechanism for populations to adapt to their ever-changing environment. The more variation, the better the chance that at least some of the individuals will have an allelic variant that is suited for the new environment, and will produce offspring with the variant that will in turn reproduce and continue the population into subsequent generations.

Sustainable use assessment, Global assessment (1st work programme)
genetic engineering

The artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms.

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

Global assessment (1st work programme)
gini index

In economics, the Gini coefficient (sometimes expressed as a Gini ratio or a normalized Gini index) is a measure of statistical dispersion intended to represent the income or wealth distribution of a nation's residents and is the most commonly used measure of inequality.

Global assessment (1st work programme), Land degradation and restoration assessment
gini index

The Gini index measures the extent to which the distribution of income (or, in some cases, consumption expenditure or other variables) among individuals or households within an economy deviates from a perfectly equal distribution. A Gini index of 0 represents perfect equality, while an index of 100 implies perfect inequality.

global

adj. Pertaining to the whole world.

Pollination assessment
global commons pool resources

Common pool resources (CPR) that have a global nature, such as the atmosphere, the oceans, global species diversity, migratory species, global biogeochemical processes, among others. It does not refer to property rights, such as a common property system. In general, CPR include natural and human‐ constructed resources in which (i) exploitation by one user reduces resource availability for others, and (ii) exclusion of beneficiaries through physical and institutional means is especially costly. These two characteristics ‐ difficulty of exclusion and subtractability ‐ create potential CPR dilemmas in which people following their own short‐term interests produce outcomes that are not in anyone’s long‐term interest.

Global assessment (1st work programme)
global commons pool resources

Global commons are resources at a planetary scale that are outside national jurisdictions. International law identifies four global commons: the high seas; the atmosphere; Antarctica; and outer space, which are recognized as the common heritage of humankind (UNEP Division of Environmental Law and Conventions).

Sustainable use assessment
