cosmocentric

A vision of reality that places the highest importance or emphasis in the universe or nature, as opposite to an anthropocentric vision, which strongly focuses on humankind as the most important element of existence.

The ways any society develops worldviews that aim at explaining the content and the dynamics of the universe, its spatial and temporal properties, the types of living beings that inhabits it, the principles and energies that explains its origin and its future.

cost-benefit analysis

an analytical tool for judging the economic advantages or disadvantages of an investment decision by assessing its costs and benefits in order to assess the welfare change attributable to it. The analytical framework of CBA refers to a list of underlying concepts which is as follows: opportunity cost, long-term perspective, calculation of economic performance indicators expressed in monetary terms, microeconomic approach, incremental approach

Cross-scale effects are the result of spatial and/or temporal processes interacting with other processes at another scale. These interactions create emergent effects that can be difficult to predict.

Land degradation and restoration assessment, Europe and Central Asia assessment, Africa assessment, Americas assessment, Asia-Pacific assessment
cross-sectoral

Relating to interactions between sectors (that is, the distinct parts of society, or of a nation's economy), such as how one sector affects another sector, or how a factor affects two or more sectors.

cross-sectoral

Relating to, or affecting, more than one sector (distinct part of society, or of a nation's economy).

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.

Values assessment
cryosphere

The components of the Earth system that contain a substantial fraction of water in a frozen state, i.e. sea ice, glaciers, ice sheets.

cryosphere

The cryosphere is those portions of Earth's surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost).

cultural ecosystem services

The Millennium Ecosystem Assessment (Sarukhán & Whyte, 2005) defined cultural ecosystem services as the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences. Cultural ecosystem services have been included in many other typologies of ecosystem services and referred to variously as cultural services (Constanza, 1997), life-fulfilling functions (Daily, 1999), information functions (de Groot et al., 2002), amenities and fulfilment (Boyd & Banzhaf, 2007), cultural and amenity services (de Groot et al., 2010, Kumar 2010), or socio-cultural fulfilment (Wallace, 2007).

Land degradation and restoration assessment
cultural change

Cultural change is a continuous process in any society, which can vary from gradual to stochastic, resulting from interactions between processes that are internal (ex. needs, local changes, crisis, mobility, ideas, invention and innovation, conflicts, etc.) and external (ex. diffusion, external agents, political and economic forces, conflicts, etc.) (Berry, 2008; Redfield et al., 1936). Cultural change is interpreted differently depending on theoretical orientation, such as diffusionism, modernization theory, world system theory, neocolonialism, globalization, among others (see Peña, 2005; Rudmin, 2009; Santos-Granero, 2009). Culture change can be selective or systemic and most often involves resistance and conflicts but can also lead to adaptation and resilience in changing contexts and environments.

Global assessment (1st work programme), Sustainable use assessment
cultural continuity

Cultural continuity has been conceptualized within Indigenous health research that builds on cultural connectedness to emphasize the importance of intergenerational cultural connectedness, which is maintained through intact families and the engagement of elders, who pass traditions to subsequent generations. Cultural continuity also situates culture as being dynamic through the maintenance of collective memory, which may change over time.

Sustainable use assessment
cultural diversity

As stated in the UNESCO Universal Declaration on Cultural Diversity, Culture takes diverse forms across time and space. This diversity is embodied in the uniqueness and plurality of the identities of the groups and societies making up humankind. As a source of exchange, innovation and creativity, cultural diversity is as necessary for humankind as biodiversity is for nature. In this sense, it is the common heritage of humanity and should be recognized and affirmed for the benefit of present and future generations..Cultural diversity widens the range of options open to everyone; it is one of the roots of development, understood not simply in terms of economic growth, but also as a means to achieve a more satisfactory intellectual, emotional, moral and spiritual existence.

Sustainable use assessment
cultural ecosystem services

A category of ecosystem services first developed in the Millenium Ecosystem Assessment (2005) to refer to the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experience, including, knowledge systems, social relations, and aesthetic values. In this assessment, cultural ecosystem services are included as part of both material and non-material Nature’s contributions to people.
