Cultural loss refers to the erosion, disappearance, or transformation of the practices, languages, identities, knowledge systems, beliefs, arts, and social structures that define a community or society.Gregory, Robin; Halteman, Philip; Kaechele, Nicole; Satterfield, Terre (2023). "Methods for Assessing Social and Cultural Losses." Science 381 (6657): 478–81. https://doi.org/10.1126/science.adi2206. Cultural loss happens in both human and non-human animal societies.Andersson, Claes; Czárán, Tamás (2023). "The Transition from Animal to Human Culture—Simulating the Social Protocell Hypothesis." Philosophical Transactions of the Royal Society B 378 (1872): 20210416. https://doi.org/10.1098/rstb.2021.0416. It may affect individual practices, entire communities, or broader cultural diversity within a population. Cultural loss thorough past and present periods is argued as highly detrimental when the loss of adaptive knowledge cascades into reduction of well-being.Riede, Felix; Sheets, Payson (2020). Going Forward by Looking Back: Archaeological Perspectives on Socio-Ecological Crisis, Response, and Collapse. https://doi.org/10.3167/9781789208641. Research has also associated perceived cultural or identity loss with changes in social attitudes and economic prospects.Klas, Anna; Clarke, Edward J. R.; Fielding, Kelly; Mackay, Matthew; Lohmann, Susanne; Ling, Mathew (2022). "Investigating How Economic and National Identity Loss Messages Impact Climate Change Policy Support."

"Bio-Cultural Refugia—Safeguarding Diversity of Practices for Food Security and Biodiversity." Global Environmental Change 23 (5): 1142–52.
In human contexts, cultural loss is experienced at several levels. At the level of practices, cultural loss may involve the discontinuation of specific skills, technologies, or traditions. At the community level, cultural loss might involve a shift of the self-identification of the people in a group, the death or assimilation of the people, and the disappearance of many of the cultural practices associated with the identity, such as language, religion, rituals, symbols, oral traditions, foods, sustenance practices, sports and games. At the population level, cultural loss can be the loss of cultural diversity over an area, due to the disappearance of identity groups, languages or practices.
Cultural loss at each of these levels may occur gradually or abruptly through processes such as prohibition,Lafferty, Catherine (2020).

Cultural loss is frequently discussed in relation to post-colonial reconciliation processes and the recognition of historical policies that suppressed indigenous cultures. These processes recognise and offer transparency to the actions and effects that such policies had on cultural loss, language loss, displacement, land eviction, boarding schools, reservations, natality control, socio-economical degradation, segregation and prohibition of cultural practices. Initiatives such as the Truth and Reconciliation Commission of Canada have examined the impacts of residential schools, land dispossession, and the prohibition of cultural practices on indigenous communities.Truth and Reconciliation Commission of Canada (2015).

The Guardian. http://www.theguardian.com/world/ng-interactive/2021/sep/06/canada-residential-schools-indigenous-children-cultural-genocide-map. In 2023, to compensate for the loss of language and culture caused by its residential school system, the Canadian government agreed to a C$2.8 billion settlement in a class-action lawsuit to compensate Canadian First Nations.BBC News (2023). "Canada Settles Residential Schools Lawsuit for $2.8bn." https://www.bbc.com/news/world-us-canada-64362246.
History and diversity of terminology Awareness of the disappearance of cultural practices can be traced back to antiquity, when historians and philosophers recorded the decline of languages, customs, and technologies in conquered or changing societies. However, systematic academic study of such processes developed much later.
One of the earliest scholarly treatments is found in the 1912 work The Disappearance of Useful ArtsRivers, W. H. R. (1912). The Disappearance of Useful Arts. Cambridge: Cambridge University Press. https://archive.org/details/disappearanceofu00riveiala. by the British anthropologist W. H. R. Rivers. Drawing on ethnographic observations in Oceania prior to sustained Western contact, Rivers documented the loss of several technologies and practices, including canoe construction, pottery production, and the bow and arrow in warfare.
Rivers proposed several mechanisms to explain the disappearance of such practices:
The death of specialised craftspeople without successors. Restricted or secret knowledge that may be lost if it is not transmitted. Gradual decline in use or prestige. Lack of access to necessary materials or environmental resources.
Although W. H. R. Rivers did not use the term "cultural loss," his analysis examined similar processes from a practice-centred perspective. His terminology, such as "disappearance of useful arts," reflects the same conceptual frame as related phenomena, including deculturalisation, "cultural loss," "culture loss," "loss of culture", and "cultural extinction.".Zhang, Hanzhi; Mace, Ruth (2021). "Cultural Extinction in Evolutionary Perspective." Evolutionary Human Sciences 3: e30. https://doi.org/10.1017/ehs.2021.25. This diversity of terms reflects the absence of a standardised field or vocabulary for describing such processes, differences in disciplinary perspectives, theoretical frameworks, and historical contexts.
Cultural loss is also interpreted as both the process of loss and the final product of having lost an element of a culture or a whole cultural identity. This dichotomy makes it difficult to group all the conversations that talk about the disappearance of cultural elements in the same category.
For the state of culture being lost, is mostly what W. H. R. Rivers refers to above. This loss outcome is more difficult to pin down, as cultural elements, or even identities, can be recovered if enough effort and capacity is invested in bringing them back. Also, convergent evolution might independently invented and adopt elements that look the same as previously lost ones, but without any cultural continuity. In these scenarios loss is only temporal from the perspective of an observer looking at deep time, notwithstanding reinnovation and readoption dynamics being clearly distinct from gradual change.
In the below definition the dynamical aspect of the process of loss is emphasised.
Definition and scope While human and non-human animal cultures have always changed over time, the term "cultural loss" is often used to describe non-linear change, in which elements of a culture disappear faster than they can be transmitted or adapted.Arinyo-i-Prats, Andreu; Sandgathe, Dennis; Riede, Felix; Collard, Mark (2025). "Use It or Lose It: A Model-Based Assessment of the Hypothesis That European Neanderthals Relied on Wildfires to Create Their Campfires." Open Research Europe 5: 205. https://doi.org/10.12688/openreseurope.20477.2.
Loss in non-human animal cultures Animal culture is widely studied and found across many domains of life, most commonly as socially learned behaviour transmitted among individuals of the same or different species that co-inhabit a space. These practices and learned behaviours are susceptible to loss, in some cases reducing the adaptability of individuals to their environments.
Loss of culture in non-human animals has received increased attention since the late 2010s, particularly in conservation research.Brakes, Philippa; Dall, Sasha R. X.; Aplin, Lucy M.; et al. (2019). "Animal Cultures Matter for Conservation." Science 363 (6431): 1032–34. https://doi.org/10.1126/science.aaw3557. Some studies argue that conservation should focus on preserving not only species and genetic diversity but also the socioecological knowledge, behaviour, and experience maintained within populations.Oestreich, William K.; Barlow, Dawn R.; Hersh, Taylor A. (2025). "Integrating Space, Time, and Culture in Animal Conservation Practice." Behavioral Ecology 36 (6): araf122. https://doi.org/10.1093/beheco/araf122. Case studies often cited in this context include elephants, whales, dolphins, migratory birds, and songbirds.
Loss in human culture, cultures, and cultural practices For humans, beyond social learning of behaviour, cultural loss involves a wide range of phenomena across at least three domains:
Cultural practices: a sudden change in which part of the cultural repertoire is no longer expressed. This may involve the loss of specific practices and their dependent elements, such as expertise, materials, tools, vocabulary, or forms of representation.
