Change and continuity seem like opposites. One pushes forward, the other holds steady. But in real human societies, both happen at the same time – often within the same community, and sometimes within the same practice. A temple might livestream its rituals on YouTube. A nomadic group might use mobile phones while still following centuries-old migration routes. Understanding how societies resist, absorb, or adapt to change is central to sustainability science, because it shapes how communities respond to environmental shifts, economic pressures, and policy interventions.

Change and continuity: two sides of the same coin
We tend to think of change and continuity as fundamentally opposed. But anthropological research shows they frequently coexist. New technologies and practices are often grafted onto existing ones rather than replacing them outright. Religious communities, for instance, may adopt smartphones and social media to broadcast prayers and ceremonies – yet the core rituals, beliefs, and social hierarchies remain unchanged. The medium changes; the meaning stays.
This pattern appears across cultures and time periods. Some aspects of a society – language, diet, technology – shift relatively quickly when exposed to external influence. Others – kinship systems, spiritual beliefs, core identity markers – resist modification for generations, even centuries. The key insight is that cultural continuity is not simply inertia or stubbornness. It often reflects deep ecological adaptation, social cohesion, and identity preservation that serve important functions for the community.
Foragers and the deep value of mobility
One of the most striking examples of cultural continuity comes from studies of hunter-gatherer societies, particularly the !Kung San of southern Africa’s Kalahari region. For decades, anthropologists like Richard Lee and Irven DeVore studied the !Kung as part of the Harvard Kalahari Project, documenting their economic systems, kinship structures, and social organisation.
What researchers found was that mobility was not just a logistical necessity for the !Kung – it was a core value. Their entire social system was built around movement. Even when some !Kung San groups took up wage labour or small-scale agriculture, they maintained traditional patterns of mobility. They would give away possessions they could not carry, reinforcing a value system that prioritised social relationships over material accumulation.
This is not irrational behaviour. It is a direct reflection of ecological adaptation. In an unpredictable environment where resources are scattered and seasonal, being light and mobile is a survival strategy. But it goes deeper than survival – it becomes identity. The !Kung’s egalitarian social structures, their practice of sharing food and “insulting the meat” to prevent any individual from gaining too much status, and their flexible group composition all flow from this core commitment to mobility and equality.
Social relationships over material accumulation
Research published in Nature Communications has demonstrated through simulation models that mobile, food-sharing hunter-gatherer families survive in unpredictable environments where sedentary or non-sharing families perish. The practice of demand sharing – where food brought into camp is claimed and divided by group members – is not a quaint custom. It is a highly effective cooperative strategy that sustains populations through lean times.
This value system also shapes how the !Kung respond to external pressures. When confronted with opportunities to accumulate goods or settle permanently, many !Kung historically chose to maintain their mobile lifestyle. Their social customs actively discourage hoarding and displays of authority, reinforcing economic equality through constant redistribution.
Prolonged contact without assimilation
One of the most powerful challenges to assumptions about cultural change comes from cases where hunter-gatherer societies maintained their distinct lifestyles despite centuries – even millennia – of contact with farming and industrialised societies.
The Aka of Central Africa
The Aka (sometimes referred to as tropical forest foragers) live in the tropical forests of the Central African Republic and northern Congo. They are one of at least ten ethnically and linguistically distinct groups of forest-dwelling people across Central Africa. The farming peoples of Central Africa moved into the tropical forest area approximately 2,000 years ago and established regular trading relationships with the Aka and other forest foragers. Farmers needed game meat and honey; forest foragers wanted cultivated foods and metal tools.
Despite roughly two millennia of sustained interaction – attending each other’s funerals, births, and marriages, and engaging in regular economic exchanges – the Aka maintained a distinct forest-dwelling identity. They continued to identify as “people of the forest” in contrast to the “people of the village”. Their camps remained small and mobile. Their social organisation stayed fiercely egalitarian. Their knowledge systems remained centred on the forest environment.
This case directly challenges the assumption that humans naturally prefer a sedentary agricultural lifestyle. If that were true, the Aka – with generations of exposure to farming communities – would have long since adopted permanent settlement. Instead, they maintained their way of life, adapting certain economic relationships while preserving core cultural patterns.
What makes assimilation resistible?
Several factors explain why prolonged contact does not automatically lead to assimilation. First, the forest environment itself rewards the specialised knowledge that foragers possess – knowledge of plants, animals, seasonal cycles, and forest navigation that farmers typically lack. Second, mobility serves as a powerful social tool. As anthropological research notes, mobility patterns allow people to “vote with their feet”, leaving situations of domination or conflict. If an Aka family feels their trading partner is exploiting them, they can simply move deeper into the forest. Third, strong egalitarian norms – including prestige avoidance and demand sharing – actively resist the hierarchical social structures that tend to accompany sedentary farming life.
Theories of sedentism and their limitations
For much of the 20th century, a prevailing assumption in anthropology was that humans naturally prefer to settle down. Sedentism – living in one place year-round – was seen as an obvious improvement over nomadic life. The logic seemed straightforward: why keep moving when you could stay put, store food, and build permanent shelter?
But the evidence does not support this assumption. Research into the origins of sedentism has identified two traditional anthropological theories – “pull” and “push”. The pull hypothesis suggests that resource abundance encouraged people to reduce mobility. The push hypothesis proposes that resource scarcity forced foragers to intensify food production in one location, reducing mobility. Both have significant empirical weaknesses.
Sedentism as a response to pressure, not preference
A growing body of evidence suggests that sedentism typically occurred only under specific pressures – environmental changes, demographic shifts, population packing, or external forces like colonisation. The earliest sedentary settlements were pre-agricultural, emerging in the Levant with the Natufian culture around 12,000 BCE, and they appeared to be responses to particular ecological conditions rather than expressions of universal human preference.
Anthropologist and political scientist James Scott has argued that many states throughout history have pursued forced sedentarisation of nomadic populations – not because settling down was in those populations’ interest, but because settled people are easier to tax, conscript, and control. Examples range from Indigenous peoples forced onto reservations in the United States to Soviet collectivisation policies targeting Central Asian nomads.
The persistence of nomadic and semi-nomadic lifestyles into the 21st century – from the Mbendjele BaYaka of the Congo Basin to pastoralists in East Africa and Central Asia – challenges any notion of a linear progression from nomadic to sedentary life. Recent genetic and anthropological research has shown that many small-scale hunter-gatherer groups continued to thrive even after being surrounded by large agricultural communities, suggesting that mobility itself was a factor in their resilience.
The impact of colonisation on traditional societies
While traditional societies have shown remarkable capacity for maintaining cultural continuity, colonialism represented a qualitatively different kind of pressure. Colonial powers did not simply coexist with indigenous communities – they actively restructured economic relationships to extract resources for European markets.
The Aka and the ivory trade
The Aka’s experience with colonialism illustrates this dynamic. At the turn of the 20th century, French colonisers of the Central African Republic and Congo wanted ivory, rubber, and antelope skins. The Aka, with their unmatched knowledge of the forest and its animal populations, became key suppliers – often through their village trading partners. The European demand for ivory increased the importance of tuma, great elephant hunters who held a special status within Aka society. Similarly, the demand for antelope skins intensified the practice of net hunting.
These changes were significant. They altered the frequency and purpose of hunting, shifted internal power dynamics by elevating certain status positions, and integrated the Aka into global commodity chains they had no role in creating. Yet the core features of Aka social life – their egalitarianism, their forest-centred identity, their mobility, their kinship systems – persisted through these disruptions.
Adaptation without assimilation
This pattern of adaptation without assimilation is found across many colonised indigenous communities. The key distinction is between surface-level economic adjustments and deep structural change. Communities may alter what they hunt, who they trade with, or what goods they produce – responding pragmatically to new economic realities. But values around social organisation, spiritual life, identity, and relationship to land often remain remarkably stable.
This has important implications for sustainability. Development programmes and conservation initiatives that assume traditional communities will naturally adopt sedentary, market-integrated lifestyles often fail precisely because they underestimate the depth of cultural continuity. The FAO has noted that the creation of protected areas should not require the removal and resettlement of forest dwellers, and that restrictions leading to “enforced primitivism” – where indigenous groups are permitted to stay only if they remain frozen in an outsider’s definition of “traditional” – are both ethically problematic and practically counterproductive.
Why cultural continuity matters for sustainability
Understanding resistance to change is not just an academic exercise. It has direct relevance to sustainability challenges we face today. Communities that have maintained traditional ecological knowledge over centuries often hold insights about sustainable resource management that modern science is only beginning to appreciate.
The !Kung San’s practice of moving before resources are fully depleted, for example, mirrors what ecologists now recommend as rotational resource management. The Aka’s deep botanical and ecological knowledge of the tropical forest – encoded in specialised vocabulary and intergenerational oral traditions – represents an irreplaceable repository of biodiversity information. When these communities are pressured to abandon traditional lifestyles, this knowledge is lost.
At the same time, cultural continuity should not be romanticised. Traditional societies are not static museums. They have always changed, adapted, and innovated – on their own terms. The challenge for sustainability science is to support communities in navigating change while respecting the social and cultural systems that have sustained them. This means moving beyond the assumption that modernisation is a one-way street and recognising that continuity and change can – and should – coexist.
What do you think? Can modern development frameworks genuinely accommodate the value systems of mobile and traditional societies, or do they inevitably push toward sedentarisation and market integration? How might sustainability initiatives be redesigned to learn from, rather than override, indigenous approaches to resource management?
