Values assessment
rewilding

Rewilding ensures natural processes and wild species play a much more prominent role in the land-and seascapes, meaning that after initial support, nature is allowed to take more care of itself. Rewilding helps landscapes become wilder, whilst also providing opportunities for modern society to reconnect with such wilder places for the benefits of all life.

Land degradation and restoration assessment
richness (biodiversity)

The number of distinct biological entities (typically species, but also genotypes, taxonomic genera or families, etc.) within a given sample, community, or area (Millenium Ecosystem Assessment, 2005).

richness (species richness)

richness

The number of biological entities (species, genotypes, etc.) within a given sample. Sometimes used as synonym of species diversity.

rightholder

A group of people (a community and its individual members), with a common identity and a shared set of rules, who rightfully has title over their territory and the natural resources belonging to it. Being a right holder implies that the group’s wellbeing is promoted by the right, and that the group (and its individual members) have the capacity to exercise their self-determination related to the given territory. From an Indigenous perspective, Right holder refers to the collective rights and entitlements of Indigenous peoples, a group of people, and a community including all individual members, with a shared cosmovision/worldview, identity, beliefs, values, and ethics. They have inherent collective rights over their territories and natural resources. Implicit in having a right holder status implies that the holder of it promotes the group's well-being and can exercise their self-determination related to the given territory.

Values assessment
rights based approach

A conceptual framework for the process of human development that is normatively based on international human rights standards and operationally directed to promoting and protecting human rights.

Asia-Pacific assessment, Land degradation and restoration assessment
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.

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
uncertainty

Any situation in which the current state of knowledge is such that: the order or nature of things is unknown, the consequences, extent, or magnitude of circumstances, conditions, or events is unpredictable, and credible probabilities to possible outcomes cannot be assigned. Uncertainty can result from lack of information or from disagreement about what is known or even knowable. Uncertainty can be represented by quantitative measures (e.g., a range of values calculated by various models) or by qualitative statements (e.g., reflecting the judgment of a team of experts).

units of analysis

The IPBES Units of Analysis result from subdividing the Earth’s surface into units solely for the purposes of analysis. The following have been identified as IPBES units of analysis globally: Terrestrial: Tropical and subtropical dry and humid forests Temperate and boreal forests and woodlands Mediterranean forests, woodlands and scrub Tundra and High Mountain habitats Tropical and subtropical savannas and grasslands Temperate Grasslands Deserts and xeric shrublands Wetlands - peatlands, mires, bogs Urban/Semi-urban Cultivated areas (incl. cropping, intensive livestock farming etc.) Aquatic, including both marine and freshwater: Cryosphere Aquaculture areas Inland surface waters and water bodies/freshwater Shelf ecosystems (neritic and intertidal/littoral zone) Open ocean pelagic systems (euphotic zone) Deep-Sea Coastal areas intensively used for multiple purposes by humans These IPBES terrestrial and aquatic units of analysis serve as a framework for comparison within and across assessments and represent a pragmatic solution. The IPBES terrestrial and aquatic units of analysis are not intended to be prescriptive for other purposes than those of IPBES assessments. They are likely to evolve as the work of IPBES develops.

upwelling

A process in which deep, cold water rises toward the surface replacing warmer water pushed away by winds. Water that rises to the surface as a result of upwelling is typically colder and rich in nutrients, which “fertilize” surface waters, meaning that these surface waters often have high biological productivity.

The wild species uses are defined through the practices of fishing, gathering, terrestrial animal harvesting, logging, and non-extractive practices. For the purposes of this assessment, the use of wild species have been divided into different categories, which are not mutually exclusive: ceremony and ritual expression, decorative and aesthetic, energy, food and feed, learning and education, materials and construction, medicine and hygiene, recreation and other: companionship.
