Land degradation and restoration assessment
common pool resource

Resources for which the exclusion of users is difficult (referred to as excludability), and the use of such a resource by one user decreases resource benefits for other users (referred to as subtractability). Common CPR examples include fisheries, forests, irrigation systems, and pastures. Global CPR examples include the earth’s oceans and atmosphere. Difficulty in excluding users, combined with a CPR’s subtractability, create management vulnerabilities that can result in resource degradation, often referred to as the tragedy of the commons. See also Tragedy of commons” and Commons”.

Land degradation and restoration assessment
common property theory

Common property theory (CPT) refers to a body of cross-disciplinary literature that deals with the historical and contemporary institutional governance and management of valued resources ranging from fisheries and forests to atmospheric sinks, oceans, and genetic materials. CPT was originally developed to understand the problems of managing what are termed common-pool resources.

Sustainable use assessment
commons

A concept whereby some forms of wealth belong to all, and that these community resources must be actively protected and managed for the good of all. It consists of land and services of common property (forests, rivers, fields and arable land) used and managed by a given community (mainly traditional, local or indigenous). The commons also consist of gifts of nature such as air, oceans and wildlife (global commons) as well as shared social creations such as libraries, public spaces, scientific research and creative works. See also Common Pool Resources” and Tragedy of the commons”.

Land degradation and restoration assessment
communication

“A two-way process aimed at mutual understanding, sharing of values and action”.

A given project attains zero net biodiversity loss when its unavoidable impacts on biodiversity are balanced out or compensated by actions such as conservation, rehabilitation, restoration and/or compensation of residual impacts that avoid or minimize losses. In this case, compensation refers to environmental compensation and not socioeconomic compensation to the people who are affected by the project’s impact.

Americas assessment
concepts

The second stage of cognitive process. Perceptions are selected, organized, classified and hierarchized into concepts. This process is influenced by collective filters which are human systems of values, norms, and beliefs. Concepts do not come alone, but as integrated networks. See also ‘Reality’; Perceptions; Worldviews”.

Europe and Central Asia assessment, Land degradation and restoration assessment
conflict

Conflict is defined as when levels of armed violence due to political insecurity, instability, or civil or international war are substantially higher than in non-conflict times. This leads to a disruption of economies, government services and the extensive movement of people to flee conflict zones for personal safety and/or better opportunities.

Sustainable use assessment
conflict

Refers to a situation where opposing attitudes, beliefs, identities, interests, norms or values coexist. This can lead to an active disagreement between people. Conflicts are likely to arise when individuals or groups in a given decision-making process feel their values are being ignored; or when they cannot agree on the underlying value rationality, or the way in which values will be integrated, traded-off or reconciled to inform a given decision. When different values collide in a decision-making situation, the conflict can be described as a value conflict.

Values assessment
connectance (in plant-pollinator networks (q.v.))

The proportion of possible links between species that actually occur (or have been observed to occur).

Invasive alien species assessment
conservation agriculture

Approach to managing agro-ecosystems for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. It is characterized by three linked principles, namely: (i) continuous minimum mechanical soil disturbance; (ii) permanent organic soil cover; and (iii) diversification of crop species grown in sequences and/or associations. This covers a wide range of approaches from minimum till to permaculture/mimicking nature.

Asia-Pacific assessment
conventional agricultural

Farming methods that rely on high inputs of machinery, fossil fuels and synthetic chemicals, including fertilizers and pesticides. Genetically modified organisms (GMOs) may also be used. Despite the term conventional, such agricultural methods have evolved only since the industrial revolution (19th century) and became widespread after the mid-20th century. It is also referred to sometimes as industrial agriculture”.

conventions

They refer to practical rules about how to undertake certain actions. They simplify interaction and facilitate coordination. Examples are the language, measurement scales (e.g. money, weight., length) and directions in the sky. Management systems, professional codes and dressing codes are other forms.

Values assessment
coral bleaching

When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
