Invasive alien species 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.

Global assessment (1st work programme)

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.

Scenarios and models assessment
correlative model

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.

Cultural identity is the identity or feeling of belonging to, as part of the self-conception and self-perception to nationality, ethnicity, religion, social class, generation, locality and any kind of social group that have its own distinct culture. In this way that cultural identity is both characteristic of the individual but also to the culturally identical group that has its members sharing the same cultural identity.

Sustainable use assessment
cultural landscape

Cultural landscapes express the long-term co-evolution and relationships between people and nature, influenced by internal and external forces affecting the aesthetic and productive configuration of land management, water bodies, wildlife, property systems, infrastructure and human settlements, and which are both a source and a product of changing social, institutional, economic, and cultural systems.
