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 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.

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.

Malnutrition refers to deficiencies, excesses or imbalances in a person’s intake of energy and/or nutrients. The term malnutrition covers 2 broad groups of conditions. One is ‘undernutrition’—which includes stunting (low height for age), wasting (low weight for height), underweight (low weight for age) and micronutrient deficiencies or insufficiencies (a lack of important vitamins and minerals). The other is overweight, obesity and diet-related noncommunicable diseases (such as heart disease, stroke, diabetes and cancer).

for the purpose of the assessment, any action taken to address the threats, risks, distribution, abundance and impacts of an invasive alien species within a defined geographic area (Hulme, 2006; Pyšek et al., 2020). Management includes prevention, preparedness, eradication, containment, and control

Invasive alien species assessment
management of wild species

The management of wild species is the management process influencing interactions among and between wild species, its habitats and humans to achieve predefined impacts valued by stakeholders. It attempts to balance the needs of wild species and the preservation of the ecosystems they inhabit with the needs of humans, using the best available sources of knowledge.

marginalization

Marginalization refers to the set of processes through which some individuals and groups face systematic disadvantages in their interactions with dominant social, political and economic institutions. The disadvantages arise from class status, social group identity (kinship, ethnicity, caste and race), political affiliation, gender, age and disability.

Global assessment (1st work programme)
marginalization

Marginalisation is a complex and multidimensional concept, which simply cannot be seen as a state of being ( a condition of low income or food insecurity) but needs to be considered a process over time with several inter-related elements interacting with social and economic conditions, political standing, and environmental health. A full understanding of the term marginalisation needs to be based on the view that the best judge of poverty and marginalisation are the people experiencing it.

Sustainable use assessment
marginalized community

Marginalized communities, peoples or populations are groups and communities that experience discrimination and exclusion (social, political and economic) because of unequal power relationships across economic, political, social and cultural dimensions (National Collaborating Centre for Determinants of Health.
