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.

sacred grove

A particular type of sacred natural sites represented by patches of forest revered as sacred (Bhagwat & Rutte, 2006). Sacred groves may be revered e.g. as burial grounds (Mgumia & Oba, 2003) or sites of ancestral or deity worship (Ramakrishnan et al., 1998). There are locally-established rules that regulate how sacred groves can be used (Hughes & Chandran, 1998). Observation of those rules often contributes to the biodiversity conservation on those sites (Bhagwat & Rutte, 2006).

Sustainable use assessment
sacred natural sites

Areas of land or water that have special spiritual significance to peoples and communities. They consist of natural features, ranging from entire ecosystems, such as mountains, forests or islands, to single natural features such as a tree, spring or boulder, and are very important for the conservation of nature and culture. Sacred natural sites have been managed based on indigenous and local knowledge systems, developed over long periods of time, and are source of cultural identity.

satoyama initiative

A global initiative with the purpose of realizing societies in harmony with nature through the conservation and advancement of socio-ecological production landscapes and seascapes (SEPLS)” around the world.

Asia-Pacific assessment
satoyama-satoumi

Satoyama is the Japanese term for a socio-ecological production landscape (SEPL) represented by a mosaic of different ecosystem types: secondary forests, timber plantations, farmlands, irrigation ponds, and grasslands—along with human settlements. Satoyama is managed through the interaction between ecosystems and humans to create ecosystem services for human well-being. Satoumi refers to Japan's coastal areas where human interaction over time has resulted in a higher degree of productivity and biodiversity. Foundational to both concepts is the positing of a relationship of interaction between humans and their environment, coupled with the notion that properly maintained the relationship is mutually beneficial.

scale paradox

Process in which land use outcomes vary (often counterintuitively) according to the geographic location and spatial scale under consideration.

Land degradation and restoration assessment
scale

The spatial, temporal, quantitative and analytical dimensions used to measure and study any phenomenon. The temporal scale is comprised of two properties: (i) temporal extent - the total length of the time period of interest for a particular study (e.g. 10 years, 50 years, or 100 years); and 2) temporal grain (or resolution) - the temporal frequency with which data are observed or projected within this total period (e.g. at 1-year, 5-year or 10- year intervals). The spatial scale is comprised of two properties: 1) spatial extent - the size of the total area of interest for a particular study (e.g. a watershed, a country, the entire planet); and (ii) spatial grain (or resolution) - the size of the spatial units within this total area for which data are observed or predicted (e.g. fine-grained or coarse-grained grid cells).

scaling

Bringing model outputs to the appropriate scale, which can be done in two different directions: upscaling information from local, fine-grained resolution to global, coarse-grained resolution; or vice versa downscaling coarse-grained information to a finer resolution.

Scenarios and models assessment
scenario

Representations of possible futures for one or more components of a system, particularly for drivers of change in nature and nature's benefits, including alternative policy or management options. Exploratory scenarios (also known as explorative scenarios or descriptive scenarios) are scenarios that examine a range of plausible futures, based on potential trajectories of drivers - either indirect (e.g. socio-political, economic and technological factors) or direct (e.g. habitat conversion, climate change). Target-seeking scenarios (also known as goal-seeking scenarios or normative scenarios): scenarios that start with the definition of a clear objective, or a set of objectives, specified either in terms of achievable targets, or as an objective function to be optimized, and then identify different pathways to achieving this outcome (e.g. through backcasting). Intervention scenarios are scenarios that evaluate alternative policy or management options - either through target seeking (also known as goal seeking or normative scenario analysis) or through policy screening (also known as ex-ante assessment). Policy-evaluation scenarios are scenarios, including counterfactual scenarios, used in ex-post assessments of the gap between policy objectives and actual policy results, as part of the policy-review phase of the policy cycle. Policy-screening scenarios are scenarios used in ex-ante assessments, to forecast the effects of alternative policy or management options (interventions) on environmental outcomes.|scale|.
