Concept Definition Deliverable(s)
rights-based and customary instrument

see “Policy instruments”.

Sustainable use assessment
rights based approach

Approaches that consider international human rights law as a coherent system of principles and rules in the field of development, and uses it as a broad guide to conducting the cooperation and aid process; social participation in that process; the obligations of donor and recipient governments; the method of evaluating aid; and the accountability mechanisms that need to be established at the local and international levels.

Americas assessment
rights-based instruments and customary norm

Synergizing rights and norms for the conservation and protection of systems of Mother Earth can foster complementarity with human well-being. International and national human rights instruments whether binding or non-binding can be creatively interpreted to fit socio-ecological systems and foster resilience. Strengthening of collective rights, customary norms and institutions of indigenous peoples and local communities, can promote adaptive governance including the equitable and fair management of natural resources.

Europe and Central Asia assessment
risk

probability of the occurrence of a particular adverse event at a specific time and the magnitude of the consequent damage caused, depending on various factors such as exposure to the hazard, the frequency of exposure and the severity of any consequent damage done (FAO, 2011b). The term risk is regarded as a product of three factors: Exposure x Likelihood x Consequence (Kinney & Wiruth, 1976). Exposure results from the introductions, establishment and spread of an alien species, whereas Likelihood is the probability of an alien species affecting nature, nature’s contributions to people, good quality of life and/or the economy, and Consequence is the magnitude of impacts if an introduction event occurs

Invasive alien species assessment
ritual uses (of wild species)

See “Ceremonial uses”.

Sustainable use assessment
rotational grazing

A grazing scheme where animals are moved from one grazing unit (paddock) in the same group of grazing units to another without regard to specific graze: rest periods or levels of plant defoliation. cf. grazing system.

Land degradation and restoration assessment
roundwood (industrial)

Industrial round wood is defined as all roundwood used for any purpose other than energy. It comprises pulpwood, sawlogs and veneer logs.

Sustainable use assessment
route of invasion

The geographic path over which a species is transported from the donor area (origin; may be defined as Last Port of Call) to the recipient area (destination or target), which may include one or more corridors.

Americas assessment
rubin causal model

Also known as the Neyman-Rubin causal model, is an approach to the statistical analysis of cause and effect based on the framework of potential outcomes, named after Donald Rubin.

Land degradation and restoration assessment
rules and regulations

Set of rules to govern the work and decision making of its formal settings.

Sustainable use assessment
rural development

Rural development is the process of improving the opportunities and well-being of rural people. It is a process of change in the characteristics of rural societies. In addition to agricultural development, it involves human development and social and environment objectives, as opposed to just economic ones. Therefore, rural development encompasses health, education, and other social services. It also uses a multisector approach for promoting agriculture, extracting minerals, tourism, recreation, and niche manufacturing.

Sustainable use assessment
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|.

scenarios

Scenarios are representations of different possible futures from a defined starting point. They are focused on highlighting or exploring drivers of change and the impacts of changes in these over a specified time frame. In doing so they enable decision-makers to anticipate potential changes and develop timely responses to these.

Values assessment
science-policy interface

Environment-related SPIs are organizations, initiatives or projects that work at the boundary of science, policy and society to enrich decision making, shape their participants’ and audiences’ understandings of problems, and so produce outcomes regarding decisions and behaviours.

Americas assessment

sea mount

A seamount is a mountain rising from the ocean seafloor that does not reach to the water’s surface (sea level), and thus is not an island. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000-4,000 m (3,300- 13,100 ft) in height.

Asia-Pacific assessment
sea surface temperature

Sea surface temperature (SST) is the water temperature close to the ocean’s surface. The exact meaning of surface varies between 1mm and 20 metres below the sea surface.

Asia-Pacific assessment
sea-level rise

The average height of the ocean’s surface is higher than the daily changes of the tides.

Asia-Pacific assessment
seascape

Seascape can be defined as a spatially heterogeneous area of coastal environment (i.e. intertidal, brackish) that can be perceived as a mosaic of patches, a spatial gradient, or some other geometric patterning. The tropical coastal “seascape” often includes a patchwork of mangroves, seagrass beds, and coral reefs that produces a variety of natural resources and ecosystem services.
