Concept Definition Deliverable(s)
community-based natural resource management

Community-based natural resource management: an approach to natural resource management that involves the full participation of indigenous peoples' and local communities and resource users in decision-making activities, and the incorporation of local institutions, customary practices, and knowledge systems in management, regulatory, and enforcement processes. Under this approach, community-based monitoring and information systems are initiatives by indigenous peoples and local community organisations to monitor their community's well-being and the state of their territories and natural resources, applying a mix of traditional knowledge and innovative tools and approaches.

Community-based tourism is defined as an approach to tourism development which prioritizes the needs and desires of the host community.

Sustainable use assessment
community-managed forest

Decentralized system of forest resource management designed to promote more equitable outcomes for stakeholders’ livelihoods changing relationships between stakeholders and government agencies.

Global assessment (1st work programme)
compensation

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”.

Land degradation and restoration assessment
conceptual framework

The Platform's conceptual framework is a tool for building shared understanding across disciplines, knowledge systems and stakeholders of the interplay between biodiversity and ecosystem drivers, and of the role they play in building a good quality of life.

confidence

See certainty.

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).

Pollination 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.

Land degradation and restoration assessment
consumer surplus

The difference between the total amount that consumers are willing and able to pay for a good or service (indicated by the demand curve) and the total amount that they actually do pay (i.e. the market price), or the difference between the consumers' willingness to pay for a commodity and the actual price (equilibrium price) they pay.

The contingent valuation method is used to estimate economic values for all kinds of ecosystem and environmental services. It can be used to estimate both use and non-use values.

Asia-Pacific assessment
convention on international trade in endangered species of wild fauna and flora

Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is an international agreement between governments. Its aim is to ensure that international trade in specimens of wild animals and plants does not threaten their survival.

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”.

Pollination assessment
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.

Geographical term for a roughly triangular area of tropical ocean that includes the coastal waters of Malaysia, Indonesia, Timor-Leste, Philippines, Papua New Guinea and Solomon Islands and is recognised as the global centre of coral reef and marine biodiversity and a global conservation priority.

Asia-Pacific assessment
correlative model

A model in which available empirical data are used to estimate values for parameters that do not have predefined ecological meaning, and for which processes are implicit rather than explicit.

Asia-Pacific assessment, Scenarios and models assessment
crowding out

It has been hypothesized that the rise of economic incentive approaches (so-called ‘market-based’ approaches) in environmental policy making, could lead to a change in values towards a commercialization of nature (i.e. people putting more weight on instrumental values and less on intrinsic values of nature in decision-making). This risks undermining intrinsic motivation or pro-nature values and mindsets.
