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).

Global assessment (1st work programme)
richness (species richness)

Ecological diversity of organisms and may be genetic to taxonomic (q.v. Biodiversity).

Pollination assessment
richness

Ecological diversity of organisms, including genetic or taxonomic diversity (q.v. Biodiversity).

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

Sustainable use assessment, Europe and Central Asia assessment, Americas assessment, Africa assessment
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

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

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
taboo

target condition

A condition that maximizes the desired mix of ecosystem services.

Land degradation and restoration assessment
target-seeking scenario

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).

Scenarios and models assessment

telecoupling

Telecoupling refers to the phenomenon that natural or anthropogenic processes in one part of the globe have an effect on a distant part of the world (Friis et al., 2016). This concept thus enables the description of flows and impacts between globally distant places in a common language. Synonym in the literature is global inter-regional connectedness.

Asia-Pacific assessment, Sustainable use assessment, Land degradation and restoration assessment, Global assessment (1st work programme)
tenure

Tenure systems define who can use which Nature’s contributions to people, for how long and under what conditions. Three related aspects of tenure offer a comprehensive understanding of the term. They include (1) tenure as a set of rights, (2) key responsibilities in relation to tenure, and (3) enabling conditions that facilitate governance of tenure. From this combined perspective, tenure is understood as the combination of a set of specific rights that connect the resource users with various aspects of the resource and puts the control and decision-making power in their hands. These rights span social, ecological, economic, and political aspects of tenure, and help provide directions to moving toward effective governance. Rights are connected with responsibilities that range from the duties of the users to maintain the resource to the duties to be performed by the state, and those jointly by both. The exercise of tenure rights can only be possible if certain conditions are meaningfully met because they offer the much required social, ecological, and political environment for the operationalization of tenure rights, performance of the tenure related duties, and necessary security and protection against tenure violations. From an integrated social-ecological (human-environmental) systems perspective, tenure is defined as relationships (also interactions and connections) between people (the users) who seek tenure and between the people (users) and the environment (includes the resource) to which tenure is being sought. Governance of tenure is then about the manner in which these host of relationships, interactions, and connections are addressed and promoted. Tenure in the context of sustainable use of wild species is not a static concept and, therefore, can be best understood as a process and its governance as continuous.

Sustainable use assessment
teratogen

Any agent that causes an abnormality following fetal exposure during pregnancy.

Americas assessment
terrestrial animal harvesting

Terrestrial animal harvesting is defined as the removal from their habitat of animals (vertebrates and invertebrates) that spend some or all of their life cycle in terrestrial environments. As for fishing, terrestrial animal harvesting often results in the death of the animal, but it may not in some cases. To reflect both situations, terrestrial animal harvesting has been sub-divided into a lethal and a “non- lethal” category. Hunting is defined as the lethal category of terrestrial animal harvesting which leads to the killing of the animal, such as in trophy hunting. “Non-lethal” terrestrial animal harvesting is defined as the temporary or permanent capture of live animals from their habitat without intended mortality, such as pet trade, falconry or green hunting. Non-lethal harvest of animals also includes removal of parts or products of animals that do not lead to the mortality of the host, such as vicuña fiber or wild honey. Unintended mortality may however occur in this category and the term “non-lethal” is therefore put in quotes.

Global assessment (1st work programme)
thermodynamics

The science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work. The behaviour of a complex thermodynamic system, such as Earth's atmosphere, can be understood by first applying the principles of states and properties to its component parts—in this case, water, water vapour, and the various gases making up the atmosphere. By isolating samples of material whose states and properties can be controlled and manipulated, properties and their interrelations can be studied as the system changes from state to state.

Land degradation and restoration assessment
threatened species

In the IUCN Red List terminology, a threatened species is any species listed in the Red List categories: critically endangered, endangered, or vulnerable.
