Concept Definition Deliverable(s)
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).

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.

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

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.

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.

degrowth

Started as an activist movement around 2008 and turned into an academic discipline, it starts from the premise that economic growth cannot be sustained ad infinitum on a resource constraint planet. It demands a deep societal change, denying the need for economic growth. It is unclear whether degrowth should be considered as a collectively consented choice or an environmentally-imposed inevitability.

Land degradation and restoration assessment
demographic change

A model describing transition in demographic profile of a population, which has been associated with the development process that transforms an agricultural society into an industrial one and characterized by a rapid population growth due to a decline in the death rate while fertility remains high initially; the growth rate then declines due to a decline in the birth rate. Before the transition's onset, population growth is low as high death rates tend to offset high fertility. After the transition, population growth is again below replacement level as both birth and death rates reach low levels.
