Researchers at Chalmers University of Technology, Sweden, have developed a new, entirely bio-based material from a somewhat unexpected ingredient: yeast. The material is 3D printed and customised for use in architectural and interior design elements that are currently made from non-renewable or fossil-based materials, such as plaster, plastic or synthetic textiles. These may be daylight modulating and sunlight protecting screens, room partitions or wall systems.

The construction sector accounts for a large proportion of global emissions and resource consumption, which means there is a great need for renewable, resource-efficient alternatives. In a new study, a research team from Chalmers investigate how industrial residual products can be used to create new materials that can contribute to greater circularity in architecture and the built environment.

The newly developed material consists of baker’s yeast, cellulose fibres from wood, alginate from algae, glycerol from plants, and water. Together, the ingredients form a kind of hydrogel – a soft, jelly-like, malleable material – that can be 3D printed.

“I’ve always been interested in the combination of architecture and living materials, and essentially this research is about creating an architectural material made entirely from organic, renewable ingredients. By combining biomaterials with digital manufacturing, we can take a novel approach to both the design and production of architectural components,” says Malgorzata Zboinska, Professor at the Department of Architecture and Civil Engineering at Chalmers, and leader of the recently published study.

Zero-waste design through 3D printing

The project combines design, materials innovation and advanced manufacturing technology. The first part of the process is similar to baking, but in slightly reverse order. First, the yeast is heated to deactivate it, and then the various ingredients are mixed together to form a smooth mass. The architectural elements can then be manufactured using pressure-based 3D printing, which is carried out at room temperature. This requires neither energy-intensive heating nor additional support structures.

“3D printing makes it possible to create complex shapes without producing waste. We can design and manufacture the material directly – with a high degree of control over its shape, texture and material distribution,” says Yagmur Bektas, a doctoral student at the Department of Architecture and Civil Engineering at Chalmers, and co-author of the study.

With minor adjustments to the formula, the material’s transparency, colour and surface texture can be altered, making it well suited for interior applications such as daylight modulating and sunlight protecting screens, wall panels or room partitions. In the long term, the yeast material could also become an environmentally friendly alternative to plastics and other petroleum-based products, such as synthetic textiles. Depending on the composition of the formula, the material takes on a natural hue that ranges from yellow to brown tones. The colour can be altered using natural pigments or pigment-producing, colourful yeast strains. It is also possible to design different patterns, vary the transparency of the material and how it feels. 

From baking and brewing to building

The use of yeast as a material component is something that has not yet been explored in architecture.

“Yeast grows exponentially. It does not require strictly controlled environments and is not particularly sensitive to contamination. Because it consists of single-celled organisms, we can produce a more homogeneous, predictable material,” explains Malgorzata Zboinska.

What makes the researchers’ new formula unique is that the yeast is not used in the usual way for fermentation, but acts as biomass. It then becomes a robust component that gives the material its volume, stability and strength. Malgorzata Zboinska also highlights the potential of using by-products from industries such as brewing and agriculture, as some of these products are often discarded. Residue that cannot be used as food or animal feed could therefore be used in architecture.

Designing with nature

Unlike traditional building materials, which are designed to last as long as possible, bio-based materials offer new ways of thinking about sustainability and material cycles. The yeast-based material is biodegradable and can return to nature after use – a key aspect of circular design.

“This challenges the traditional notion that materials must last forever, or at least have as long a physical life cycle as possible. Instead, we can think in terms of shorter life cycles and even view the ageing or degradation of the material as part of the design,” says Malgorzata Zboinska.

Self-healing or purifying materials on the horizon

Although the results show great potential, further research is needed before the material can be used widely in buildings. Future studies will assess key properties such as strength, fire safety and moisture performance, as well as scaling up digital manufacturing and developing stronger and more robust structures.

“The future of architectural ELMs, or Engineered Living Materials, is very exciting, with great potential to customise them to perform a variety of functions. This could, for example, involve self-healing materials or materials that purify the air by neutralising harmful substances and pollutants. What we have achieved so far is an important first step towards establishing a completely new type of architectural material. You could say that we are laying the foundations for future developments that combine sustainability, functionality and design in entirely new ways,” says Malgorzata Zboinska.

 

More about the material and how it is made:

The material consists of baker’s yeast (dry yeast), cellulose fibres (from wood), alginate (from brown seaweed), glycerol (from plants) and water. Each component contributes a specific function to the final material. Glycerol acts as a plasticiser and provides flexibility, whilst alginate contributes to the dimensional stability required for 3D printing. Cellulose further contributes to dimensional stability and acts as a structural component that provides tensile strength when the material is under load. The yeast acts as a binding agent for all the ingredients and gives the mixture its viscosity. Before mixing the ingredients to form a hydrogel, the researchers deactivate the yeast, which is necessary to stabilise the material. The hydrogel is 3D printed using air pressure and left to dry at room temperature until it achieves its final shape.

“Japanese Migration to Canada, 1877–1988,” a new reference essay by Masumi Izumi, was published in Oxford Research Encyclopedia of Migration Studies in April 2026. As part of the expanding Oxford Research Encyclopedia series, the article offers a sweeping and deeply researched account of Japanese migration to Canada from the arrival of the first documented migrant in 1877 through the Canadian government’s formal redress settlement of 1988. Drawing on decades of scholarship in migration studies, Asian American/Asian Canadian history, and trans-Pacific studies, Izumi’s essay situates Japanese Canadian history not as an isolated ethnic narrative, but as a central chapter in the broader history of settler colonialism, labour migration, citizenship, and civil rights in North America. 

Beginning with the rise of labour migration to British Columbia in the late nineteenth century, the article examines how Japanese migrants worked in fisheries, logging camps, mines, and agricultural industries while establishing enduring trans-Pacific family and community networks. Rather than portraying migration as a one-way process, Izumi emphasizes the ongoing circulation of people, ideas, and economic ties between Japan and Canada.

The article highlights the development of vibrant prewar Japanese Canadian communities through businesses, schools, newspapers, religious organizations, and mutual aid societies. Special attention is given to the role of women and families in stabilizing immigrant life and shaping the emergence of Canadian-born Nisei generations. At the same time, Izumi demonstrates how anti-Asian racism and exclusionary policies profoundly shaped Japanese Canadian experiences throughout this period.

A central section of the essay examines the forced removal and incarceration of approximately 23,000 Japanese Canadians during World War II. Izumi documents how families were uprooted from the Pacific Coast, dispossessed of homes and businesses, and confined in camps and interior settlements under wartime emergency measures. The article underscores the lasting consequences of these policies. Importantly, the article refuses to frame Japanese Canadians solely as victims. Izumi foregrounds the resilience, political activism, and community rebuilding efforts that emerged both during and after incarceration. She explores how Japanese Canadians challenged state policies, rebuilt institutions after the war, and pursued redress for historical injustices.

The article culminates with the landmark 1988 redress settlement, in which the Canadian government formally apologized and provided compensation to surviving victims of wartime dispossession and incarceration. Izumi presents this moment not only as a milestone in Japanese Canadian history, but also as a defining episode in global debates over citizenship, minority rights, and state accountability. 

A professor at Doshisha University in Kyoto, Izumi has written extensively on Japanese Canadian activism, wartime incarceration, civil liberties, and Asian North American social movements. Izumi argues that the Japanese Canadian experience remains a critical historical warning about how democracies can suspend civil rights under conditions of fear and political pressure. The article serves as a valuable teaching and research resource for students and scholars in migration studies, Canadian history, Asian diaspora studies, settler colonial studies, and transnational history.

The full article, “Japanese Migration to Canada, 1877–1988,” by Masumi Izumi, is available through the Oxford Research Encyclopedia of Migration Studies.

South China Sea tensions drive a quiet realignment against Beijing

South China Sea tensions drive a quiet realignment against Beijing
/ IntelliNewsFacebook
By Mark Buckton in Taipei June 4, 2026

The geopolitical map of maritime Asia is gradually changing. Not dramatically so and not by way of formal alliances, but through a steady coming together of interests among states increasingly concerned by China's growing power in the South China Sea region.

Nowhere else is that clearer than in the Philippines.

For years, Manila has maintained unofficial and close ties with Taiwan just to the north, while carefully observing Beijing’s preferred ‘One China’ policy. That position has not formally changed as was seen in late March when both countries came together in Quanzhou, Fujian Province for the 24th China–Philippines Foreign Ministry Consultations then last month when the Philippines participated in the APEC Ministers Responsible for Trade meeting in Suzhou, China.

The practical relationship though is becoming steadily deeper, particularly in the fields of security and maritime affairs. To this end, recent comments from Philippine Defence Secretary Gilberto Teodoro mark perhaps the strongest public signal yet.

Speaking in the past week at the Shangri-La Dialogue in Singapore, Teodoro said the Philippines was seeking closer ties with Taiwan as part of a broader effort to deter China's "nefarious plans". In doing so, he described Taiwan, Japan and Vietnam as part of a growing network of countries pursuing what he called a "convergence endeavour" aimed at strengthening regional security, according to Taiwan’s Taipei Times.

Speaking so openly against China is rarely done at this level.

For decades, many Southeast Asian governments have actively sought to avoid being drawn into any tensions related to the Taiwan Strait and Chinese claims on democratic Taiwan. However, today that is changing. Philippine officials increasingly view Taiwan's security as directly linked to their own. At their closest point the shortest distance between Taiwan and the Philippines is just 88 miles across the Bashi Channel between southern Taiwan and the Batanes Islands of the northern Philippines.

Geography thus explains much of this shift. Taiwan sits just north of the Philippines across the Luzon Strait – of which the Bashi Channel makes up the southern part – a waterway through which global military forces and commercial shipping move between the Pacific and the South China Sea. Because of this proximity to internationally used waterways, any conflict involving Taiwan would almost inevitably affect the Philippines, most noticeably in the form of blocking trade routes and national security.

In recent years, Manila's concerns have intensified as confrontations with Chinese vessels have become more and more frequent around disputed features in the South China Sea (see map above).

Philippine officials on an almost weekly basis warn that Chinese activities pose a significant security threat regardless of the on-again, off-again bromance between US President Donald Trump and Chinese President-for-life, Xi Jinping.

At the same time, unofficial links between Taiwan and the Philippines have broadened with trade figures pointing to Philippine imports from Taiwan rising 18.6% year-on-year to over $4.7bn in 2025 and Manila’s exports to Taiwan up 22.1% year-on-year at $3.3bn. Because of this, Taiwan is now among the Philippines’ top 10 trading partners, local Taiwanese media reports.

Bloomberg also recently reported growing exchanges involving business leaders and security officials holding discussions on coastguard cooperation and maritime security. While still falling short of formal defence cooperation in any official manner, the direction the relationship is taking is increasingly clear.

Add to this Taiwan's role in advanced semiconductor production on the global stage and the nation’s role as a tech supplier is evident for both the Philippine government in Manila and others across Asia.

In turn, Taiwanese President (William) Lai Ching-te, like his predecessor, has repeatedly argued that stability in the Taiwan Strait is critical not only for regional security but also for global supply chains.

As such, for the Philippines, attracting Taiwanese investment and in particular technology offers economic benefits alongside potentially military aid in the event of conflict with the result being a relationship that is increasingly ‘official’ in all but name.

The Philippines is not alone – other countries bordering the South China Sea are also starting to push back against China.

Surprisingly given shared Communist ideals is Vietnam, which has become one of the region's most active challengers of Chinese maritime claims. In doing so, Hanoi continues to expand facilities and reclaimed land on islands and reefs it occupies in the heavily contested Spratly chain, while at the same time it maintains extensive political and economic ties with Beijing, according to The Star.

That China and Taiwan as well as Malaysia, the Philippines, and Brunei also claim parts of the Spratlys only complicates the issue.

Vietnam's approach though is often described as "bamboo diplomacy" in that it is highly flexible and designed to avoid choosing sides – shared border with China notwithstanding – with President To Lam of Vietnam recently indicating the importance of strong relations with China while simultaneously reaffirming Vietnam's commitment to protecting its sovereignty and maritime interests, according to Reuters.

Yet beneath the diplomatic language, Hanoi continues building on the islands it currently occupies, strengthening its position in contested waters.

This, coupled to Vietnam's decision earlier in the week to elevate relations with the Philippines to an an enhanced partnership of sorts only reflects the shared concern felt in both Manila and Hanoi as both governments declared that peace and a rules-based order in the South China Sea were "non-negotiable", according to Reuters. In the days since, China has offered little in the way of response.

Malaysia presents a different case altogether, however, as Kuala Lumpur remains much more cautious than either Manila or Hanoi. Prime Minister Anwar Ibrahim has consistently pushed for dialogue and regional solutions rather than any form of confrontation and Malaysia continues to pursue extensive economic engagement with China while at the same time avoiding inflammatory rhetoric – in part perhaps as a result of its long-standing cultural and historical links to China with over 20% of Malaysians being ethnic Chinese.

Even so, Kuala Lumpur has quietly strengthened cooperation with Vietnam and continues to defend its own maritime claims. Bloomberg reported in late 2024 efforts by Vietnam and Malaysia to boost trade and to coordinate more closely on maintaining stability and freedom of navigation in the South China Sea.

Elsewhere around the South China Sea, a similar pattern is emerging.

Japan and the Philippines have deepened defence ties. Australia has increased security cooperation across Southeast Asia and Canada and New Zealand are also becoming more active participants in regional maritime initiatives. None are actively looking for confrontation with Beijing and all are seeking greater resilience against potential coercion, according to Bloomberg.

China, meanwhile, is getting increasingly aggressive and continues to assert its myriad claims across the South China Sea. Part of this has seen Chinese forces increase coastguard and maritime patrol activity around disputed areas thousands of kilometres from Chinese shores. Daily air and naval intrusions into Taiwanese economic zones and airspace are the norm for the nation of 24mn.

As such, the significance of Manila's growing engagement with Taiwan extends beyond bilateral ties or agreements to work together and reflects a broader regional trend in that Asian governments are not forming an explicit anti-China bloc. Instead, most remain deeply dependent on trade with Beijing and continue to seek stable relations, but they are slowly coming together to stand up to the neighbourhood bully.

Governments around the South China Sea are increasingly coordinating with one another, in terms of trade and militarily to prepare for a future in which China's maritime ambitions may spill over into open hostilities.

For now, the Philippines has simply moved further and faster than most.

 

Sudan, DRC top annual Norwegian Refugee Council ranking of world's neglected displacement crises

Sudan, DRC top annual Norwegian Refugee Council ranking of world's neglected displacement crises
/ bne IntelliNewsFacebook
By bne IntelliNews June 5, 2026

Sudan and the Democratic Republic of the Congo (DRC) are the world's most neglected displacement crises, as humanitarian funding, media attention and political engagement continue to fall short of growing needs, according to an annual ranking by the Norwegian Refugee Council (NRC).

In its 2025 Neglected Displacement Crises Report, the humanitarian group said the 10 most neglected crises for the year also include Colombia, Yemen, Afghanistan, Honduras, Ecuador, Cameroon, Nigeria and Mozambique, “spanning three continents and tens of millions of people the world continues to ignore”.

In Sudan, more than 9 million people are internally displaced, and up to 4 million have fled to neighbouring countries, according to the NRC, and nearly 19.5 million people inside the war-torn North African are facing hunger. But, the group said, the international response remains wholly inadequate to that scale of suffering.

“It is incomprehensible that a displacement crisis of similar proportions to the crises in Syria and Ukraine at their peak can continue to worsen almost unnoticed,” NRC Secretary General Jan Egeland said. “Just as needs in Sudan skyrocketed last year and famine kept spreading, the funding was cut. Many displaced people receive no international support and are left to beg for assistance from other displaced people who no longer have anything more to share.”

The DRC has been among the world's most neglected displacement crises now for 10 consecutive years, it said. Only 27.4% of the funding required for the DRC humanitarian response was provided last year, it said, characterising it as the lowest coverage rate recorded in a decade. More than 21mn people in the mineral-rich country – plagued by years of conflict – are in need of assistance as a result.

“This is a testament to the world's failure to respond to crises that are not regarded as strategically important for rich countries,” Egeland said. “Millions of people are being abandoned because we have chosen not to act, not because we cannot. The uncomfortable truth is that this neglect is a choice, and something we can choose to end.”

According to the report, international humanitarian support for the DRC has declined sharply over the past decade. While donors provided approximately $55 per person in need in 2016, that figure has fallen to less than $33 today despite escalating humanitarian challenges.

The NRC said a pattern of chronic underfunding extends across several African crises. Countries including Burkina Faso, Cameroon, the Central African Republic, Mali and Nigeria have appeared repeatedly in the annual ranking, which measures neglect through four indicators: funding levels, media coverage, political attention and displacement scale.

“Donor governments have been presented with evidence of neglect, year after year. Yet those in power still choose to prioritise military and strategic investments and underfund, deprioritise and sideline the victims of these crises. It is a failure of our humanity,” Egeland said.

The report warned that the humanitarian situation in eastern DRC is being compounded by a public health emergency. The NRC noted that an Ebola outbreak spreading across parts of eastern Congo is unfolding in communities already affected by years of conflict, displacement and inadequate humanitarian support.

“Behind every statistic in eastern DR Congo are families who have endured years of violence, repeated displacement, and deep uncertainty about their future,” said Eric Batonon, NRC's country director in the DRC. “While attention shifts from one global emergency to another, millions of Congolese continue to live without adequate protection, assistance, or hope.”

Globally, humanitarian appeals received $15.95bn in funding against requirements of $45.47bn in 2025, leaving a funding gap of $29.5bn, according to data cited by the NRC. The organisation called on donor governments to allocate aid according to humanitarian need rather than geopolitical priorities and urged greater diplomatic engagement with the root causes of displacement.

The Norwegian Refugee Council is an independent humanitarian organisation that provides assistance and protection to displaced people and refugees worldwide. It publishes its annual Neglected Displacement Crises Report to highlight emergencies that receive limited international attention and funding.

David Montgomery Hart And The Moroccan Rif: Anthropology, Segmentarity, And Intellectual Legacy – Analysis




LONG READ


Abstract

This essay examines the work and intellectual legacy of David Montgomery Hart (1927–2001), an American anthropologist whose fieldwork in the Moroccan Rif, conducted primarily between 1952 and the 1970s, constitutes one of the most substantial contributions to Maghrebi anthropology of the twentieth century (Chtatou, 2016; Ramírez & López García, 2002). Drawing on his monumental monograph The Aith Waryaghar of the Moroccan Rif (1976), the essay traces Hart’s intellectual formation, his ethnographic method founded on prolonged immersion, and his deployment of the segmentary model to analyse Riffian tribal organisation. It then examines the theoretical controversy opened by Henry Munson Jr. (1989), who contests the relevance of the segmentary lineage model as applied to the Rif, and analyses Hart’s rejoinder and Ernest Gellner’s positions (1969, 1981) in this structuring debate for the anthropology of the Maghreb. The essay concludes with an assessment of the legacy of Hart’s work in contemporary Amazigh studies and in the cultural history of the Rif.

1. Introduction: An Anthropologist Confronting the Rif

The history of the anthropology of northern Morocco is, in many respects, the history of a passionate engagement between foreign scholars and a human territory of extraordinary complexity. Among these scholars, David Montgomery Hart occupies a singular position: not simply because he devoted several decades to the study of Riffian tribes, but because the depth of his immersion, the scope of his documentation, and the rigour — sometimes contested — of his theoretical framework produced a corpus of rare density in North African studies (Chtatou, 2016). Born on 18 May 1927 in Philadelphia and died on 22 May 2001 in Garrucha, Spain, Hart lived between two worlds: the American academic world in which he had trained, and the Rif and southern Spain where he had made his home and found his vocation.

The Rif, a mountain massif in northern Morocco running along the Mediterranean from Tangier to the Moulouya, constitutes an anthropological terrain of exceptional richness. It is a space where armed resistance, embodied by the Rif War (1921–1926) and the figure of Abd el-Krim al-Khattabi, coexists with an elaborate tribal organisation, customary legal practices rooted in Amazigh tradition, and a vibrant oral culture (Pennell, 1986). When Hart began his fieldwork there in 1952, he inherited a tradition inaugurated by Carleton S. Coon, whose monograph Tribes of the Rif, published in 1931, had laid the first foundations of American Riffian ethnography (Coon, 1931). Hart would surpass this precedent, both in the duration of his commitment and in the sophistication of his approach to social structures.

This essay proposes to analyse Hart’s work in its threefold dimension: biographical and methodological first, examining his training, his fieldwork methods, and his insertion into the academic networks of his era; theoretical next, with the examination of his recourse to the segmentary lineage model and the debates it generated (Munson, 1989; Hart, 1989); and patrimonial finally, with an evaluation of the legacy left by his work in Amazigh studies and contemporary Maghrebi anthropology (Ramírez & López García, 2002). In so doing, the essay endeavours to situate Hart not only within the North African anthropological landscape, but also within the broader epistemological context of social anthropology in the second half of the twentieth century.

2. Intellectual Formation and Academic Context

2.1. From Philadelphia to the Rif: The Career of a Fieldwork Ethnographer


David Montgomery Hart completed his doctoral studies at the University of Pennsylvania under the supervision of Carleton S. Coon (1904–1981), one of the most influential — and, with time, most controversial — figures in twentieth-century American anthropology. Coon was the author of Tribes of the Rif (1931), a monograph whose publication had coincided with the final phases of Riffian resistance to the Spanish protectorate and which constituted, despite its methodological limitations stemming from an anthropology still marked by typological assumptions, the first serious ethnographic synthesis on the Amazigh populations of northern Morocco. For Hart, studying under Coon meant inheriting both a subject matter — the Berbers of the Maghreb — and an intellectual style: that of the fieldwork ethnographer who goes into direct contact with the populations, far from libraries and abstract models (Chtatou, 2016).


Hart began his fieldwork in the Rif in 1952, at the age of twenty-five. He would gradually settle among the Ait Waryaghar, the most important tribal confederation of the central Rif, whose territory extends around Al Hoceima. This initial immersion lasted several consecutive years; Hart would return regularly to the region throughout his career, totalling approximately eleven years of effective presence in the Rif (Chtatou, 2016; Ramírez & López García, 2002). He also taught at the Institute of Sociology of the University of Mohammed V in Rabat during part of this period, enabling him to maintain an institutional Moroccan anchorage while pursuing his fieldwork.

What distinguishes Hart from many of his contemporaries is his remarkable linguistic mastery. Hart was fluent in Tarifit (the variety of Tamazight spoken in the Rif), Moroccan Arabic, Classical Arabic, as well as Spanish, French, and German (Chtatou, 2016). This polyglottism was not incidental: it conditioned the quality of his access to oral sources and to the ethnographic literature produced in various European languages on northern Morocco. His ability to read Spanish and French archives directly, while conducting interviews in Tarifit, allowed him to cross-reference sources of a radically different nature and to produce analyses of exceptional documentary density (Joffé & Pennell, 1991).

Hart is often described as an anthropologist of the ‘old school’ — an expression taken up by Akbar Ahmed in his preface to Islam in Tribal Societies (Ahmed & Hart, 1984). This expression designates a manner of practising anthropology that makes prolonged presence in the field, participant observation, and mastery of local languages the sine qua non conditions of all valid knowledge. In this perspective, Hart aligns himself with the lineage of the great ethnographers of the twentieth century — Evans-Pritchard in the Sudan (1940), Malinowski in Melanesia, Barth in Iran — who defined the standards of the ethnographic monograph through total immersion. This intellectual lineage explains both the strengths and the limitations of his work: it guarantees its factual richness and documentary authenticity, while exposing it to critiques of a theoretical paradigm — segmentarity — that would prove more fragile than anticipated.

2.2. Hart in the North African Anthropological Landscape

To understand Hart’s place, it is necessary to situate him within an academic field where several major figures were working simultaneously on Morocco. Ernest Gellner (1925–1995) began his fieldwork in the High Atlas in 1954, producing Saints of the Atlas (1969), a monograph that would become the theoretical reference for the segmentary model applied to the Maghreb. Clifford Geertz, working in Sefrou in the Middle Atlas, developed an interpretive anthropology centred on systems of cultural meaning (Geertz, 1968). Paul Rabinow (1977) and Vincent Crapanzano (1980) would introduce in subsequent years a postmodern reflexivity that would call into question the epistemological foundations of classical ethnography. Dale Eickelman (1976) worked on popular Islam and the sociology of Quranic education.

In this panorama, Hart occupies a particular position: he is the specialist of the Rif, that northern region often marginalised in the major syntheses on Morocco, which more readily focus on the imperial cities of the centre or on the Berber High Atlas (Chtatou, 2016). His work fills a considerable gap in the anthropological literature, and does so with a documentary exhaustiveness that his contemporaries unanimously acknowledge, even when contesting his interpretations. Together with Carleton S. Coon and Ernest Gellner, Hart is generally considered one of the foreign scholars who contributed most to the anthropological knowledge of the Moroccan Rif (Chtatou, 2016; Joffé & Pennell, 1991).


Hart maintained an intensive correspondence with his colleagues that constitutes in itself an academic object. Gellner noted that Hart had developed and perfected a distinctive literary form: the long ethnographic letter (Laâbi & López García, 2020). This correspondence, totalling more than ten thousand pages exchanged notably with Ross E. Dunn, was entrusted to the National Archives of Morocco, attesting to its value as a historical and anthropological source of the first order. This intensive epistolary practice reveals a conception of anthropological knowledge not as a finished and systematic product, but as a permanent dialogue, an accumulation of details that resist theoretical reduction (Laâbi & López García, 2020).


3. The Ethnographic Work: Documenting the Tribal Rif

3.1. The Aith Waryaghar of the Moroccan Rif (1976): A Monumental Monograph



The centrepiece of Hart’s work is unquestionably The Aith Waryaghar of the Moroccan Rif: An Ethnography and History, published in 1976 in the Viking Fund Publications in Anthropology series (No. 55) by the University of Arizona Press for the Wenner-Gren Foundation (Hart, 1976). With its 556 pages and its double title — ethnography and history — the work deliberately situates itself at the junction of two disciplines. Hart does not limit himself to describing Riffian society synchronically, as if it existed outside of time: he interweaves ethnographic data from his fieldwork with a long-term historical reconstruction, drawing on Spanish and French colonial sources, oral traditions collected from his Riffian interlocutors, and the work of his predecessors, foremost among them Coon (1931).

The structure of the work reflects Hart’s intellectual preoccupations (Hart, 1976). It devotes entire chapters to the segmentary organisation of lineages (tiqbaylin, ighs, adrum), to customary law practices (izerf), to the institutions of arbitration and conflict management such as the liff (ritual alliance), to agricultural and pastoral practices, to life-cycle ceremonies, to religion and its local expressions, and of course to the history of Riffian resistance. This ethnographic encyclopaedism is both the strength and the limitation of the work: it makes it an inexhaustible reference source for all scholars working on the Rif, while sometimes obscuring a central and coherent theoretical argument (Munson, 1989).


The academic reception of the work was unanimously positive regarding the quality of the documentation. E. G. H. Joffé, in a review published in the Journal of African History in 1977, praised the exceptional richness of the ethnographic material assembled by Hart (Joffé, 1977). The Arabic translation of the work, produced by Mohammed Ouniba, Abdelmajid Azouzi, and Abdelhamid Rais, and published by the SMDN in the Netherlands in 2007, attests to its reach beyond Anglo-Saxon academic circles and its importance for Riffian communities themselves (Chtatou, 2016).

3.2. Other Works: Dadda ‘Atta, the Tribe, and Rural Society

Alongside his work on the Rif, Hart conducted research on other Amazigh tribal societies in Morocco. His work Dadda ‘Atta and His Forty Grandsons, published in 1981, extends his tribal comparativism to the Grand Atlas and the northern Sahara (Hart, 1981). The Ait ‘Atta, a tribal confederation of pre-Saharan Morocco, present structural similarities with the Ait Waryaghar while differing in their transhumance patterns and forms of political organisation. This comparative work is of great importance for evaluating the segmentary model, as it allows Hart to extend his conclusions beyond the Rif alone (Munson, 1993).

His volume Tribe and Society in Rural Morocco (Hart, 2000) assembles articles published over several decades and reflects the thematic diversity of his interests: from kinship systems to vengeance practices, from the structure of periodic markets to forms of tribal leadership. As early as 1967, Hart had published in the Revue de l’Occident Musulman et de la Méditerranée a foundational article entitled ‘Segmentary Systems and the Role of Five Fifths in Tribal Morocco’, which laid the theoretical bases of his reflection on segmentarity (Hart, 1967). One should also mention his comparative contributions on Pashtun tribes in Pakistan and Afghanistan, conducted in collaboration with Akbar S. Ahmed (Ahmed & Hart, 1984), which reveal a theoretical ambition extending beyond the Moroccan framework alone.

4. The Ethnographic Method: Immersion and Participant Observation


Hart’s method is that of classical ethnography as defined by Malinowski and Evans-Pritchard (Evans-Pritchard, 1940): prolonged presence, mastery of the language, participant observation, systematic collection of life narratives and oral traditions, cross-referencing of data from different sources. This approach is extraordinarily demanding in its execution: it requires a tolerance for uncertainty, a capacity to inhabit between two cultures, and a working discipline that transforms the researcher’s daily experience into documentary data (Rabinow, 1977).

Hart lived with Riffian families, shared their meals, attended their festivals and ceremonies, and accompanied the men on their movements and agricultural activities. He collected genealogies — those fundamental instruments of tribal memory that allow the reconstruction of kinship ties, matrimonial alliances, and land rights over several generations (Hart, 1976). This genealogical collection, tedious and technically difficult owing to orthographic variations in Berber proper names and the fluidity of tribal identities, constitutes one of the most enduring contributions of his work (Chtatou, 2016).

His wife, Ursula Kingsmill Hart, also played an important role in fieldwork, particularly in gaining access to female spaces that were closed to Hart as a man. Her book Behind the Courtyard Door, published in 1994, offers a complementary perspective on the lives of Riffian women, a dimension that Hart’s masculine ethnography could not fully grasp (Hart, U. K., 1994). This conjugal collaboration in the field constitutes a rare example of anthropological research conducted jointly in societies with strong gender segregation.

Hart also produced detailed reports, often very long, addressed to colleagues and correspondents, in which he recorded his daily observations, ongoing reflections, and unresolved questions — what Gellner called the ethnographic letter (Laâbi & López García, 2020). This hybrid form, between field diary and academic correspondence, reveals a particular intellectual temperament: that of a scholar who thinks through accumulation and cross-referencing, more at ease in detailed ethnographic narration than in the construction of abstract and falsifiable models.

The question of the objectivity of Hart’s gaze on the Rif deserves to be raised. Like any ethnographer, Hart was not a neutral observer: he carried an American academic training of the 1950s, a personal interest in tribal societies, and a deep affinity for Riffian culture that is apparent in his writings (Chtatou, 2016). The postcolonial critique of anthropology — as it developed from the 1980s onward (Rabinow, 1977) — would invite an examination of the conditions of production of Hartian knowledge: who speaks on whose behalf, and within what framework of colonial or postcolonial power? This questioning does not disqualify Hart’s work, but enriches its critical reading.

5. Tribal Segmentarity: Model, Application, and Controversies

5.1. The Segmentary Model and Its Theoretical Origins


The model of tribal segmentarity, as applied by Hart to the Rif, has its origins in British social anthropology of the 1940s, particularly in Evans-Pritchard’s work on the Nuer of the southern Sudan. In The Nuer (Evans-Pritchard, 1940) and African Political Systems (Evans-Pritchard & Fortes, 1940), Evans-Pritchard described a type of political organisation characteristic of stateless societies: groups organise themselves into nested segmentary lineages, such that units that oppose one another at a given level form coalitions against a common enemy at a higher level. This principle of complementary opposition — often summarised in the formula ‘I against my brother, my brother and I against our cousin, my cousin and I against the stranger’ — allows for the regulation of conflicts and alliances in tribal societies without permanent central authority.

This model had been adapted to the North African context by Robert Montagne in the 1930s, notably in Les Berbères et le Makhzen dans le Sud du Maroc (Montagne, 1930). But it was Ernest Gellner who formulated its most ambitious version in Saints of the Atlas (1969), where he analyses Berber society in the central High Atlas as a paradigmatic example of segmentary organisation, showing how saints (igurramen) serve as necessary arbiters between segments in unstable equilibrium. For Gellner (1981), the segmentary model is not merely an empirical description but an analytical tool for understanding the political dynamics of Islamic tribal societies in general.

Hart had begun applying the segmentary model to the Rif independently of Gellner, from the very beginning of his fieldwork in 1952. His 1967 article in the Revue de l’Occident Musulman (Hart, 1967) establishes the theoretical bases for the Riffian case. The collective edition Islam in Tribal Societies (Ahmed & Hart, 1984) illustrates the intellectual convergence between Hart and Gellner while demonstrating their comparative ambitions. For Hart, the Ait Waryaghar exhibited a clearly articulated segmentary structure, with levels of organisation ranging from the nuclear family (akham) to the lineage (adrum), the clan (ighs), and the tribe (taqbilt), these units nesting according to a logic of opposition and alliance (Hart, 1976, pp. 69–103).

5.2. Munson’s Critique: Segments or Factions?

The most serious and thoroughly documented challenge to Hart’s application of the segmentary model came from Henry Munson Jr. in an article that has become a classic of North African anthropology: ‘On the Irrelevance of the Segmentary Lineage Model in the Moroccan Rif’, published in American Anthropologist (Munson, 1989). Munson’s argument is both empirical and theoretical.

On the empirical level, Munson argues that Hart misread his own data (Munson, 1989, p. 390). Re-reading carefully the 1976 monograph and the colonial sources on which Hart relied, Munson finds that violence in the pre-colonial Rif typically involved brothers and brothers’ sons competing for inherited land — a resource controlled by individuals, not by lineages. What Hart interpreted as a system of segmentary lineages was in reality, according to Munson, a network of cross-cutting factions cutting across genealogical lines. The observed alliances did not follow the nested opposition principle predicted by the model, but rather responded to logics of clientelism, individual land competition, and political opportunism (Munson, 1989, pp. 392–396).

On the theoretical level, Munson inscribes himself within a broader critique of the segmentary model developing in the anthropology of the 1980s: scholars such as Philip Carl Salzman and Emrys Peters had pointed out that the model, despite its formal elegance, tended to project a normative structure onto social realities that were far more fluid and contingent. The segmentary model, according to this critique, is less a description of tribal reality than an ideological representation produced by the actors themselves to legitimate their alliances — what Bourdieu would call a ‘native theory’ of social practice (Munson, 1989, pp. 386–389).

Munson adds a further argument concerning the role of the Makhzen in the pre-colonial Rif. Hart, he argues, had greatly underestimated the political impact of the Moroccan state on the Rif, presenting the tribes as autonomous entities whose dynamics could be analysed independently of their relation to the state (Munson, 1989, pp. 397–398). This critique connects to broader debates about the nature of pre-colonial Morocco, notably the work of Abdallah Laroui, who had contested the image of a bled es-siba (dissidence territory) fundamentally separate from the bled el-makhzen (territory under state control). In his later work, Munson (1993, 1995) extended this critique to the entire Gellnerian corpus, demonstrating that the empirical contradictions identified in the Rif applied equally to other regions of Morocco.

5.3. Hart’s Rejoinder and the Transcendence of the Model


Hart responded to Munson in a ‘Rejoinder’ published in the same issue of American Anthropologist (Hart, 1989), defending his reading of the Riffian data while conceding certain points. The response reveals an anthropologist more at ease in ethnographic description than in theoretical jousting: he insists on the irreplaceable value of fieldwork data and expresses a deep mistrust of abstract models that, in his view, fail to account for the complexity of the real. His formulation is revealing: he affirms that ethnography is, or was, the real heart of socio-cultural anthropology, and that anthropological theory is but a facade compared with ethnographic facts (Hart, 1989, p. 768).

This position — which one might describe as militant anti-theorism — is both the manifestation of a certain intellectual honesty and a real conceptual limitation. Hart implicitly acknowledges that the richness of his fieldwork data exceeds the capacity of the segmentary model to order it satisfactorily. In his 1993 article (Hart, 1993), ‘Faulty Models of North African and Middle Eastern Tribal Structures’, Hart himself revises the most mechanical applications of the segmentary model, drawing closer to Munson’s criticisms. This revision represents a remarkable example of intellectual probity: few anthropologists of his generation accepted so publicly to revise their fundamental interpretive framework (Ramírez & López García, 2002).


Gellner, for his part, maintained until his death in 1995 the validity of the segmentary model, reformulating it more sophisticatedly in Muslim Society (1981). The Hart-Munson-Gellner controversy thus constitutes one of the most fertile debates in Maghrebi anthropology of the second half of the twentieth century (Tobolka, 2003), mobilising fundamental questions about the relation between theoretical models and empirical data, between structure and agency, between synchrony and history. It prefigures the postmodern debates on ethnographic representation and anticipates the postcolonial critiques of the structuralist tradition in anthropology.

6. Hart and the Rif War: History and Memory


An often-neglected aspect of Hart’s work is his treatment of the Rif War (1921–1926) and the figure of Abd el-Krim al-Khattabi. Hart was not only an ethnographer of the tribal present: he was also a historian attentive to the ways in which this recent past — and particularly this war of exceptional importance for Riffian collective memory — structured the collective representations and political identities of the populations he studied (Hart, 1976, pp. 369–430). His data on the Riffian oral tradition relating to the Rif War constitute an irreplaceable source for historians of that period (Pennell, 1986).

The Rif War, in which the Ait Waryaghar played a central role under the leadership of Abd el-Krim al-Khattabi, had been the first modern asymmetric guerrilla war to inflict a significant military defeat on a European colonial power — Spain, at the disaster of Annual in 1921 (Pennell, 1986, pp. 112–134). The French intervention in 1925 and Abd el-Krim’s surrender in 1926 brought to an end the brief experiment of the Republic of the Rif. For Hart, this recent history was not merely contextual background: it was constitutive of the political identity and social organisation of the Ait Waryaghar he observed in the 1950s and 1960s (Hart, 1976).

Hart’s research on the Rif War is conducted in dialogue with the work of C. R. Pennell, whose A Country with a Government and a Flag (1986) constitutes the standard historical synthesis. Pennell and Hart share an interest in the institutional dimension of the Republic of the Rif — Abd el-Krim’s government as a proto-state experiment — and in the transformations that the war imposed on traditional tribal structures (Joffé & Pennell, 1991). The tension between segmentary tribal organisation and state-building, at the heart of the Riffian experience of the early twentieth century, is precisely the problematic knot that Hart seeks to untangle through his ethnography.
7. Legacy and Intellectual Posterity

7.1. Hart in Contemporary Amazigh Studies


The death of David Hart in May 2001 prompted numerous tributes in academic and Amazigh circles, reflecting the dual dimension of his legacy: scientific on one side, human and political on the other (Chtatou, 2016). The collective volume Antropología y Antropólogos en Marruecos, coordinated by Ángeles Ramírez and Bernabé López García (2002), assembled contributions from scholars in several countries to assess his work. This volume attests to Hart’s international recognition as a founding figure of contemporary Riffian anthropology.

Within Riffian communities themselves, and more broadly within the Amazigh movement, Hart is generally perceived as an ally and sympathetic witness to a culture long marginalised by the Moroccan and Spanish states (Chtatou, 2016). His documentation of Riffian customary institutions — the liff, the izerf, forms of tribal arbitration — provided an ethnographic argument against colonial and nationalist representations that denied the complexity and dignity of Riffian civilisation (Hart, 1976; Chtatou, 2016). The Arabic translation of his monograph, published by a Riffian association in the Netherlands in 2007, constitutes a powerful act of symbolic reappropriation: the descendants of the populations studied by Hart now have access, in their own language, to the documentation he produced on their ancestors.

Reflection on the postcolonial dimension of Hart’s anthropology is necessarily nuanced. On one hand, his work participates in an academic tradition that sometimes reproduced essentialising representations of so-called ‘tribal’ societies (Rabinow, 1977). On the other hand, Hart himself resisted certain of the most reductive tendencies of colonial anthropology. His sympathy for Riffian populations, his refusal to present them as mere objects of study, and his commitment to preserving documentation of their culture testify to a research ethics that transcends the academic framework (Chtatou, 2016; Ramírez & López García, 2002)
.
7.2. Influence on Subsequent Generations

The influence of Hart on the scholars who succeeded him in the study of the Rif and Amazigh societies is difficult to overestimate. The monograph on the Ait Waryaghar (Hart, 1976) remains, fifty years after its publication, the indispensable reference for anyone wishing to study the social organisation, history, and culture of the tribes of the central Rif. It is cited in works of history, sociology, customary law, linguistics, and gender studies dealing with the contemporary Rif, attesting to a rare interdisciplinary reach (Chtatou, 2016; Joffé & Pennell, 1991).

Scholars who worked on the Rif after Hart — whether C. R. Pennell (1986) for history, or Mena Lafkioui for Berber linguistics — often define themselves in relation to him, either deepening certain of his analyses or correcting them on the basis of new data or new theoretical perspectives (Ramírez & López García, 2002). This position of foundational reference is the clearest sign of the durability of his legacy.

One should also mention the importance of Hart’s correspondence, preserved in the National Archives of Morocco (Laâbi & López García, 2020). These ten thousand pages of letters constitute an exceptional archive not only for the history of North African anthropology, but also for the social and cultural history of the Rif in the second half of the twentieth century. Their systematic study remains largely undone and promises significant discoveries. Clifford Geertz, in his posthumous tribute to Hart, placed him at the centre of the romantic image that each generation of anthropologists working in Morocco forms of Moroccan fieldwork: the exulting ethnographer, present body and soul in the field of inquiry (cited in Ramírez & López García, 2002, p. 12).

8. Conclusion: An Ambiguous and Indispensable Legacy

The work of David Montgomery Hart is simultaneously a monument and a contested one. A monument, because it constitutes the most complete ethnographic documentation ever produced on the tribal societies of the Moroccan Rif, the fruit of several decades of immersion conducted with remarkable rigour and intellectual generosity (Chtatou, 2016; Joffé & Pennell, 1991). Contested, because the theoretical framework organising it — the segmentary lineage model — proved insufficient to account for the complexity of Riffian social and political dynamics, as the debate with Munson clearly established (Munson, 1989; Hart, 1989).

This ambivalence is not unique to Hart: it characterises a large part of classical twentieth-century ethnography, caught in the tension between the demand for empirical presence and the temptation of theoretical elegance (Rabinow, 1977). What Hart illustrates with particular clarity is the risk of over-theorisation: when the richness of fieldwork data is filtered through a model that is too powerful and too closed, it emerges impoverished, reduced to examples of a pre-existing structure rather than expanded into a new understanding of the social world (Munson, 1989; Hart, 1993).

The post-1989 shift in Hart — his critical retreat from the segmentary model in his 1993 article (Hart, 1993) — is, from this perspective, exemplary of a rare intellectual probity. It suggests that a fieldwork anthropologist of Hart’s calibre always retains, at bottom, the primacy of observation over theory. This priority is perhaps the most enduring lesson he leaves us: in the human sciences, data resist models, and it is in this resistance that the possibility of an advance in knowledge resides (Ramírez & López García, 2002).

For Amazigh and Riffian anthropology in particular, Hart remains an indispensable figure, not despite his limitations but alongside them. His work has opened a space of knowledge about a region long invisible in international academic production (Chtatou, 2016), and continues to feed research in disciplines as diverse as history, linguistics, law, sociology, and cultural studies. Hart’s posterity is that of a founder: he laid the foundations, traced the first maps of an intellectual territory that other explorers have come to complete, correct, and enrich (Ramírez & López García, 2002; Joffé & Pennell, 1991).

The profound attachment Hart showed for the Rif and its inhabitants — to the point of maintaining a repeated presence there for half a century — transcends the framework of an academic relationship (Chtatou, 2016). It testifies to a form of anthropology that has not yet entirely disappeared: one in which research is inseparable from personal commitment, from a relationship of affection and respect for the societies studied. It is this commitment, as much as his erudition, that makes David Montgomery Hart an irreplaceable figure in the history of knowledge of northern Morocco.
