Capitalism and commodity frontiers

Considering the spectacular rise in the growing of agricultural commodities and the mining of minerals in the past centuries, and the stunning and ongoing social and environmental effects of their production and circulation, it is not surprising that many scholars from a variety of disciplines have tried to grasp the underlying mechanisms of commodity frontier expansion.

Economists have contributed much to our understanding of these issues, especially their discussion of whether and to what extent capitalism can resolve the social and ecological crises it has created. We learn from Edward Barbier’s monumental Scarcity and Frontiers that over the past centuries, some commodity frontiers sustained successful resource-based development, while many more collapsed under social and ecological pressures. ^{Footnote 4} We also discover that capitalist production has created and extracted a wealth of new agricultural commodities and minerals across the world, while polluting bodies of water, land and people, depleting and salinizing soils and degrading the very conditions of its own reproduction. Many economists conceptualize these processes by emphasizing that capitalism tends to externalize social and ecological costs, and that the best way to correct such imbalance is to internalize them. In both economic research and policy-making, internalizing externalities has become a widely accepted approach to furthering global sustainability. Neoclassical economists are especially optimistic about such ecological accounting. Paul Collier, one of this field’s most prominent voices, promotes an analytical tool he calls ‘right prices’ and highlights the role of ‘inclusive and transparent institutions’ in defining and regulating such prices.Footnote ⁵

Ecological economists, on the other hand, have looked at the same set of facts and come to very different understandings. Economist Joan Martinez-Alier, along with human ecologists working on distributional conflicts such as Alf Hornborg, for example, are sceptical that capitalist externalities can be priced into submission. They offer alternative conceptions of how to define capitalism’s ecological problems, seeing them as the political results of uneven distribution.Footnote ⁶ They deploy concepts such as social metabolism and unequal ecological exchange to analyse how the flows of energy and materials between places and peoples generate and maintain inequalities. These scholars contend that the capitalist system, rather than being able to self-correct by pricing externalities, is based on crushing forms of ecological debt created by rich nations underwriting their growth with the resources of poor nations. For these scholars, past centuries have been marked by industrializing societies – almost always colonial powers – compensating for their ecological deficits by imperialist exploitation. ^{Footnote 7} By opening new frontiers of commodity cultivation, production, extraction and waste disposal, these countries have exported problems of pollution, soil degradation, poor labour conditions and social upheaval to poorer countries. Geographer David Harvey – one of the most prominent voices in this debate – refers to this process as capital’s ‘spatial fix’ – the extraction of resources by dispossession and labour from local communities, resulting in highly uneven development.Footnote ⁸

Development studies scholars provide yet another set of approaches to understanding commodity frontiers by asking why many resource-rich countries tend to be characterized by low levels of economic growth, massive economic inequality and high rates of poverty. Neoclassical economic explanations for this ‘paradox of plenty’ or ‘resource curse’ tend to centre on issues of incorrect pricing, misallocation of development revenues and inadequate institutional quality and oversight.Footnote ⁹ Critical economists and political ecologists, especially in Latin America, argue, in contrast, that this outcome is not a paradox, but rather the direct result of outside actors and institutions extracting minerals, raw materials and forest and agricultural resources and exporting them along with the water, energy, labour and knowledge that they embody. To conceptualize that impact of commodity frontier expansion, these thinkers use notions of extractivism, neo-extractivism and post-extractivism.Footnote ¹⁰ Other scholars, including Mattias Borg Rasmussen, Christian Lund and Nancy Peluso, use the concept of territorialization to explain how patterns of resource exploration, extraction and commodification have dissolved existing social orders and reordered spaces. The reshaping of social and economic orders around new resource frontiers profoundly reworks patterns of authority and institutional architectures such as property systems, political jurisdictions, rights and social contracts.Footnote ¹¹

Insights from these debates are germane for studying the social and environmental foundations and the effects of capitalism’s commodity frontiers in the global countryside. But even as various disciplines converge around studying the social and environmental foundations and effects of capitalism’s commodity frontiers, their concepts remain siloed in discrete literatures. What is more, many (though not all of them) tend to focus on contemporary problems, their analysis limited by a failure to fully consider the many centuries of commodity frontier expansion.

The importance of history

Historical concepts are crucial, however, in situating present issues in longer trajectories to highlight the patterns that will ultimately help us find new analytical tools to grapple with our present. Of course, there is a long tradition of looking at capitalism historically, and indeed a distinguished group of social scientists – from Werner Sombart and Fernand Braudel to Immanuel Wallerstein and Alain Bihr – has argued that global capitalism emerged on the eve of the Columbian voyages across the Atlantic, that capitalism, in fact, was born global.Footnote ¹² For this group of scholars and others in that tradition, commodity frontier expansion was a key marker of capitalism from its very beginning.

No one has done more to understand capitalism as a system encompassing distant places and people than Terence Hopkins and Immanuel Wallerstein, the developers of the concept of the commodity chain. ^{Footnote 13} Their aim was to show the emergence of a worldwide division of labour about 600 years ago, a system that typically connected rural commodity-producing regions in the periphery with processing industries and consumers, typically in cities located in what they called the ‘core.’ These production processes, they argued, were ‘cross-cutting political jurisdictions,’ expanding over time, and subject to structural transformations.Footnote ¹⁴ Because the commodity chain concept sees commodities as ‘containers of hidden social relations’, it concentrates on people working on commodity frontiers, the places where they work, the conditions they work under and the social relations governing their work and production.Footnote ¹⁵

Feminist scholars working in this tradition, importantly, have expanded the scope of the commodity chain to include the unwaged household work that produces labourers and the ‘free gifts of nature’ that contribute to the making of commodities and commodity frontiers.Footnote ¹⁶ They have endeavoured, as Wilma Dunaway put it, to make visible those ‘transfers of value that are embodied in commodities but do not show up in prices’.Footnote ¹⁷

In recent years, global historians have picked up on some of these ideas. Studies on the history of particular commodities, for example, have persuasively illustrated the deep links between agriculture and industry, the countryside and the city and the household and production. These studies have revealed how the global emerged from local configurations and have shown the essential role played by the politics, ideas and collective actions of non-elite actors such as rural cultivators, especially in the Global South, in shaping commodity frontiers, and thus the political economy of global capitalism.Footnote ¹⁸ Similarly, many scholars have been sensitive to the ecological dimension of economic and technological divergence between ‘core’ and ‘periphery’. Environmental historian and historical geographer Jason W. Moore, for example, has argued that since for most of human history technological advances were slow and piecemeal, the global economy derived much of its growth from an unstinting expansion of vast frontiers of labour, food, energy and raw materials. ^{Footnote 19} Sidney Mintz made the point abundantly clear in his Sweetness and Power, observing how slave labour produced cheap sugar for the emerging British industrial proletariat. Slave-based sugar and cotton supplied calories and clothing that industrialising Britain could never have procured from its own soil. In the words of historian Kenneth Pomeranz, these processes provided Britain with ecological relief. ^{Footnote 20}

It is at this point that Jason W. Moore’s argument that global capitalism is organized through frontiers becomes especially relevant. For him, these frontiers have expanded from one place to the next, transforming socioecological relations as they go, producing more and more goods and services that circulate through an expanding series of exchanges. Valued by a growing number of scholars from different disciplines as a problem-oriented transdisciplinary approach to historical processes, Moore’s commodity frontier concept invites a radical rethinking of the commodity chain approach from which it emerged. Commodity chain analysis starts from what its advocates have called ‘the core’ and works downstream towards peripheral locations of subaltern production, crop cultivation, mineral extraction and so on. The commodity frontier approach, in contrast, begins with the countryside – a significant departure. It moves analytically from chains of (labour) relations to frontiers of spatial expansion that include not only labour, but the incorporation and extraction of non-human nature.

Yet capitalism never changed solely by expanding in space and scale. It also experienced fundamental shifts in character, including in the dominant patterns of commodity frontier expansion. Analysing and understanding how these patterns varied across time and place, how and why such variations were institutionalized and how and why key dynamics changed requires a reflection on the periodization of capitalism. An influential approach here is that of Harriet Friedmann and Philip McMichael’s work on successive food regimes. Concerned with ‘the role of agriculture in the development of the capitalist world economy, and in the trajectory of the state system’, their food regime concept has been debated, critiqued and carried further in the past 30 years.Footnote ²¹ Recently, Friedmann has amended a rather rigid structural conceptualization of food regimes by bringing agency and social movements more centrally into the frame. For her, a regime is constituted by a ‘relatively stable set of relationships’ with ‘unstable periods in between shaped by political contests over a new way forward’.Footnote ²² Meanwhile, McMichael specified that the food regime is foremost an analytical device and historical method to pose specific questions about the structuring processes of the global political economy, and/or global food relations, at any particular moment.Footnote ²³ Food regimes as a concept have thus developed into a device for periodization and a proposal for a comparative historical method that links broad political-economic change to local agency and contestation.

Commodity regimes

All the approaches outlined above illuminate important aspects of the expansion of commodity frontiers during the past six centuries. Yet, each is limited in its own way. Much of the writing on the history of capitalism produced during the past 150 years privileges a perspective from the city, from industry and from labour outside the household; not surprisingly, considering that most of these authors were men who resided in cities located in industrializing countries. Yet, the vast majority of humanity has lived and worked, until very recently, in rural and domestic places, and it was in these places that many of the revolutions of capitalism have taken place. And while commodity histories and commodity chain analysis have persuasively shown the deep links between agriculture and industry and the countryside and the city, their focus on single commodities has limited their ability to capture the expansion of commodity frontiers across several centuries and around the world as a whole. Global historians have captured some of these general processes, but their all-too-frequent privileging of top-down perspectives and elite actors has led them to ignore how the global, including global commodity frontiers, has emerged from local configurations of social space and social power. Scholars who focus squarely on commodity frontiers have often concentrated on single factors to illuminate their dynamics, insisting, for example, on master explanations like the ‘spatial fix’ (Harvey and Moore) or the ‘technical fix’ (neoclassical economists) and failing to historicize particular responses to particular moments of commodity frontier expansion. ^{Footnote 24} Last but not least, many discussions of contemporary commodity frontier dynamics (i.e. land grabbing, flex crops, extractivism) fall into the trap of emphasizing the newness of developments that go back many centuries and can only be understood via a historical perspective.

What we need, instead, is to analyse commodity frontiers through a historical approach that (1) keeps multiple frontiers in the view over a very long time period, (2) focuses on a variety of actors, including capitalists, rural cultivators (peasants and slaves, men and women, indigenous people and state bureaucrats), (3) takes both a global and a local view to scrutinize frictions, contestations and counter movements from the household to the international arena and (4) asks how commodity frontiers have transformed in fundamental ways over the past 600 years, producing new kinds of dynamics, encountering particular resistances and constructing new fixes.

The concept of commodity regimes allows us to identify moments in the history of commodity frontiers in which particular sets of labour relations and property rights, patterns of land ownership, forms of the insertion of capital, state policies and technologies come to define a given historical period. It is a meta-historical device that allows us to capture the ways in which different societal domains on commodity frontiers (ecological, technological, social and political) are organized and relate to one another; it allows us to periodize and subdivide as needed, while still understanding the unity of the diverse.

Over time, we see that commodity frontiers exhibited regular, albeit shifting, combinations of labour systems, property regimes, technologies and state interventions. Any systematic analysis of the long history of these frontiers needs to begin by acknowledging this diversity. But we also need to acknowledge certain patterns. Properly analysed, these patterns help us understand the changing character of commodity frontiers as a constituent in the historical development of capitalism.

We can distinguish, roughly speaking, four distinct commodity regimes during the past centuries of capitalism’s history, with the transitions from one to the next propelled by key transformations such as the abolition of slavery, the Industrial Revolution, the emergence of powerful state bureaucracies both in the industrializing countries of the North Atlantic and the colonial peripheries, and over the course of the twentieth century, the massive concentration of corporate enterprises.

The first such regime, which lasted from the 1450s through the 1850s, can be termed an early capitalist commodity regime. It was characterized by direct and violent dispossession of people from land and nature and by unfree labour systems that included chattel slavery, peonage and indentured contract labour. ^{Footnote 25} Its forceful expansion was sanctioned by states, but its principal expansionary driver was merchant capital. The sugar commodity frontier is exemplary for this particular regime. Sugar production principally expanded because ever more land was violently taken out from underneath its native inhabitants, ever more workers were enslaved, and ever more capital moved from Europe into distant locations. Merchant capitalists and planters exerted a decisive influence on this commodity frontier, often ruling faraway places and organizing the day-to-day domination of labour. By the end of this period, maroonage and rebellion emerged as central social contestations, while technological advances propelled new and deeper forms of exploitation of both labour and nature.

The second regime, from the 1850s to the 1970s, can be described as an industrial commodity regime. It was characterized by the massively expanding use of fossil energy, soaring industrial and state demand for commodities and the rise of multinational capital, global bulk commodity markets and new transport and communication technologies. These factors reinforced infrastructural capabilities ranging from the telegraph to railroads, shaping the conditions under which commodity frontiers expanded, including the contractual mobilization of land and labour.

While the forms this transformation took were complex and varied across time and space, four central features can be distinguished: the conversion of a system of customary land rights into legally defined titles to land ownership; the transformation of the concept of property from ambiguously defined areas to concretely defined, possibly enclosed, physical spaces; the rationalization of the use of such demarcated landed property as a form of capital and the increased privatization of the earth’s surface through dispossession and displacement of peasants and indigenous populations. Sharecropping, tenant farming, indentured servitude and wage labour increasingly replaced non-economic labour coercion such as enslavement. Massive colonial projects fuelled the commodification of land, while land grabs abolished communal peasants’ rights and developmental projects or state-sponsored collectivization schemes led to further expropriation and displacement. Agricultural science, in turn, brought productivity leaps, eventually leading to the Green Revolution of the 1960s. Like the previous commodity regime, the industrial commodity regime was always contested, with labour activism and anti-colonial movements joining older forms of resistance.

The industrial commodity regime had enormous staying power and was propelled to new heights by the rapid economic expansion in the three decades after the Second World War. However, by the 1970s, it started to unravel and be replaced by a new corporate commodity regime. Slow economic growth hit numerous commodity-producing countries particularly hard, reducing their governments’ abilities to mitigate market volatility and forcing them to accept structural adjustment programmes. This reinforced the changing role of the state vis-à-vis transnational corporations and financial institutions, as well as new global political divisions amongst and between North and South, simultaneously reproducing and remapping imperial, colonial and Cold War political geographies. The concentration of power in the hands of a few producers took a quantum leap as commodity trade and financial institutions became tightly connected from the 1980s on. Capitalist agriculture created new commodified inputs (seeds, fertilizers, pesticides, etc.) and legal protections for corporate ownership, resulting in further power concentrations at commodity frontiers. A massive contraction of land rights accelerated the growth of a rural proletariat on a world scale, and resistance movements acquired a transnational character.Footnote ²⁶

Cracks in the corporate commodity regime became visible with the Great Recession and the world food crisis in 2008, spurring a fourth – still tentative – contemporary commodity regime. In this emerging regime, key elements of the previous regimes are reintegrated and intensified. For instance, firms already entrenched at the top of commodity markets and financial actors looking for new investment opportunities have come to own or finance increasing amounts of land around the world, largely through dispossession, often with the assistance of state power, best expressed in the newly fashionable public-private partnerships (PPPs). Green capitalism, built on the co-optation of sustainability discourse, continues to create new products and frontiers for accumulation, amongst them organic foods, biofuels and the optimistically named clean coal.Footnote ²⁷ Rising authoritarianism around the world is pressuring people and environments on commodity frontiers in South America, the USA, South East Asia and elsewhere. At the same time, new dynamics are coming into view in this post-2008 era that Klaus Schwab, Executive Chair of the World Economic Forum, has called the ‘fourth industrial revolution’.Footnote ²⁸ Companies (often with state assistance) are expanding into radically new production and information technologies, including new automated (robot) labour in manufacturing, households and agriculture. Relatedly, new digital infrastructures that extract data and mediate between different groups have become increasingly important for commodity frontiers. Examples of what Nick Srnicek calls platform capitalism include agricultural implements manufacturer John Deere’s data collection systems that record farmers’ activities and commodify the data and mobile phone-based money transfer and (micro)financing services such as Vodafone’s M-Pesa that operate in East Africa and elsewhere, and China’s new ‘Study the Great Nation’ social platform that collects user data for surveillance and advertising.Footnote ²⁹ As this regime is still unfolding, questions about which processes and relations will be most important, which will spur or encounter the most resistance, and what forms that resistance will take remain.

These four regimes have engendered widely divergent forms of expansion and exploitation, showing capitalism to be highly adaptive and flexible. And like capitalism more broadly, each regime contains profound tensions, generating fierce contestation. Approaching the history of capitalism through commodity regimes speaks against a teleological or linear interpretation of the relationship between capitalism and the countryside, as Figure 1 clearly shows, and aids us in uncovering capitalism’s shifting historical and spatial logic. Figure 1 is our effort to describe in a tentative way and at the most general level how we propose to investigate frontier expansion as a series of cumulative frictions and fixes.

Figure 1.

Commodity regimes, frictions and fixes.

Commodity regimes and their frictions

The expansion of commodity frontiers was not a smooth unfolding of one universal logic or of unstinting human progress, but a series of regimes that transformed themselves in quite fundamental ways at certain moments. These transformations occurred because each regime ran into frictions that eventually made the further expansion of commodity frontiers impossible without fundamental changes. Preliminary investigations suggest that these regimes succeed each other at an accelerating pace, going from 400 years for the first regime to 30 years for the third. Market convergence and the increased momentum of technological change as well as growing resistance might account for fundamental frictions occurring more frequently. But these are assumptions that we want to test. In doing so, our point of departure is that commodity regimes encounter frictions along three central axes: (1) ecological frictions, (2) competition for land and labour (3) and social resistance, including counternarratives that contest the existing commodity regime.

To begin with, ecological frictions have imposed an important set of limitations on commodity frontier expansion. In the early phases of capitalism, ecological frictions such as declining soil fertility forced the production of agricultural commodities or minerals to move into new areas. Later, crippling diseases that swept through populations of uniformly bred crops and livestock instigated the quest for disease-resistant plant varieties, broad-spectrum pesticides and fungicides, more powerful vaccines and tightly controlled production systems with labour-disciplining biosecurity measures. Ecological damage caused by commodity agriculture or extraction rendered many frontiers unproductive or uninhabitable, often causing the end of the production of this particular commodity at this location. Deserted mining regions around the globe, the problem of severe water shortages and salinization surrounding the irrigated cotton fields in Central Asia, the wheat frontier in the USA and its degeneration into the infamous Dust Bowl in the 1930s are all examples of collapsed commodity frontier zones caused by ecological frictions.

Likewise, frictions arising from competition for land and labour have destabilized many commodity frontier zones. Rebellions of enslaved and servile women and men were a permanent feature of the frontier zones during the early capitalist commodity regime. Slavery became increasingly untenable due to resistance by enslaved people such as the revolution in Saint-Domingue in 1791 and the large-scale uprising in Jamaica in 1832, as well as the emergence of an abolitionist movement. Labour shortages were a perennial problem for commodity frontiers; in fact, during the many centuries in which mechanization proceeded slowly, labour supplies were the main limiting factor for commodity production. Once slavery was abolished and tropical commodity agriculture left its plantation enclaves, it increasingly inserted itself into existing rural societies, where it had to compete for land and labour. Thus the expansion of global capitalism increasingly encroached upon existing land rights, often using large-scale destruction of communal land ownership and outright dispossession and displacement of peasants and indigenous populations. This massive accumulation through dispossession has been a source of permanent, often violent, conflict.

Across the four regimes, commodity regime expansion produced other social frictions as well. As merchants, chartered companies, colonial officials, mining capitalists and frontier planters, amongst others, expanded into new territories and new productive activities, appropriated new land, extracted new materials and incorporated new labour, their ongoing attempts to externalize the social and environmental costs of production and reproduction were met with resistance. Coupled with ecological limits, such resistances can prefigure and compel regime change, pushing capital to seek new frontiers. During the early capitalist regime, for instance, revolt and desertion (maroonage) were responses to enslavement and servitude and helped propel the shift to sharecropping and wage labour. During the industrial regime, strikes, working-class political mobilizations and unionization, together with anti-colonial movements, joined rebellion and escape as forms of insurgency. Later, as corporate-headed transnational commodity chains integrated global production in the corporate regime, resistance has also become transnational. Workers struggled against capital’s ‘race to the bottom’, indigenous communities against the polluting and degrading activities of transnational corporations that often operate with near impunity, peasants against the incursions of transnational capital into agrarian spaces. In some cases, resistance also provided counternarratives and counterproposals for different ways of organizing political, economic, social and ecological life – in recent years, for example, by seeking collaborative, locally embedded, equitable or non-growth-based forms of production. Because counter movements suggest some of the key themes around which people are exploited or oppressed, studying resistance within regimes is a crucial part of defining and analysing the regimes themselves – and helping to explain how over time they changed fundamentally.

Commodity regimes and their fixes

Frictions and resistances were part of each commodity regime over the centuries, usually culminating in systemic crises. In response, new commodity regimes emerged, characterized by particular fixes or combinations of fixes. Each ensemble was particular to particular moments in the history of global capitalism. The fixes, as described in Figure 1, were (A) the spatial fix, (B) the technological fix, (C) the state-led fix and (D) the corporate fix. Although each new fix was hailed as the master key to resolving the then-current limits to commodity frontier expansion, they were usually not entirely new. Moreover, older fixes did not disappear. Spatial fixes, for example, remain powerful today, usually at the expense of tropical rain forests, grasslands, indigenous communities and biodiversity.

Nonetheless, the spatial fix was most pronounced during the early capitalist commodity frontier regime, when the state was distant and quite weak and most increases in output came from additional inputs of land and labour. Until the late eighteenth century, the consequences of soil exhaustion caused by sugar, tobacco or coffee plantations, for example, were almost always overcome either by using additional labour to perform manuring or by adding more land for crop rotation. Labour shortages were addressed by immigration of either free or enslaved workers, as happened in most of the plantations of the New World. From the late eighteenth and particularly the early nineteenth century onward, a new set of fixes emerged to join the continuing spatial expansion. In the early stages of capitalism, technology had only a limited impact on productivity. The Industrial Revolution changed this, as it resulted in massive mechanization of both agriculture and mining and immense improvements in transportation, although these innovations entered the commodity frontiers unevenly and increased rural inequalities through class differentiation and lay the ground for future ecological distribution conflicts.

Increasingly, the state came to play a more prominent role in commodity frontier expansion. Where the expansion of commodity frontiers had previously been driven by a particularly violent type of capitalism exerted by merchant capital and sanctioned by the state, in the nineteenth and twentieth centuries states attained the infrastructural capability needed to shape the conditions under which frontiers operated. Infrastructure construction, financial legislation, sponsored migration of contract labour and legislation and implementation of new property rights regimes all featured as prominent new forms of state interventions. While technology-enabled global commodity production to soar after the systemic crisis that attended the abolition of the slave trade and slavery itself, these technological innovations would not have materialized without the new role played by the state.

Science, moreover, produced leaps in agricultural productivity, including the Green Revolution at the end of the industrial commodity regime. Differential access to technology and the ways that capitalist agriculture created new commodified inputs (seeds, fertilizers, pesticides, etc.) engendered new dependencies for farmers, ^{Footnote 30} thus leading to further concentrations of power at the commodity frontier. The current stage of biotechnology enables the integration of the food and energy sectors and a profound appropriation of life through seed patents and intellectual property protections, leading to further large-scale dispossessions. In fact, over time, the state-led fix has paved the way for a transnational corporate enterprise to become the dominant force on commodity frontiers, which continues – not without contestation – in the contemporary regime.

Capitalism has been driving the creation of increasingly integrated and complex commodity chains, massively changing the relationship between commodity frontiers and processing industries. Significant convergence of commodity prices appeared by the late eighteenth century; information systems connected the global countryside with industrial centres by the mid-nineteenth century; the concentration of power in the hands of a few end producers intensified during the twentieth century, especially in the 1980s when commodity trade and financial institutions became tightly connected. Currently, a narrow range of mostly transnational corporations controls much of the expansion of commodity frontiers through direct ownership of land and means of production and contracting, subcontracting, digital data collection and general control of commodity circulation.Footnote ³¹ Much of the economic risks and the environmental and social costs of corporate-led production are dumped on marginalized people and places, while new calls for sustainability are co-opted into opportunities to deepen Green Capitalism in the new commodity regime.

The framework of commodity regimes takes commodity frontiers as an analytical point of departure, sensitizing us to geopolitical shifts, the role of the state, technology, ecology, and last but not least, local agency. This is to say that capitalism develops not only through incorporation and commodification, but also through what resists it. Non-human nature is not flat, constant or given: soils give out, water becomes scarce or toxic, wells run dry, ‘weeds’ and microorganisms develop resistance to agrochemicals and antibiotics. At the same time, social movements and civil society initiatives compel capital to adjust to the demands of organized groups of people, sometimes creating new avenues and segmented markets for capital such as fair trade and organic labelling in food, and sometimes creating a barrier for capital to overcome, such as wage labour.

A research strategy

It is challenging to translate the framework of commodity regimes into a workable research strategy; this challenge, of course, also pertains to global history’s project of making wide-ranging comparisons across large time spans and geographic regions.Footnote ³² A commodity frontiers research project directly engages with ongoing debates about the ambitions, promises and limits of global and world history. It requires building collaborative and discipline-crossing research networks. It offers methods and sources for a history that aims to surpass or delegitimize the old Eurocentric stories of the rise of a unified world.Footnote ³³

We aim for an inductive approach that studies localized experiences and global systemic movements and past experiences and contemporary problems within a single analytical framework. This requires that we overcome the fragmented and individualized character of archival research and fieldwork, which, because they are so labour intensive, usually produce geographically and temporally limited work. The immense library of existing case studies does not add up to a systematized body of knowledge. Another challenge – one that again pertains to global history more broadly – is to move beyond privileging the national level as a unit of analysis. Many historical indicators of development – per capita income, demography, migration, balance of trade, etc. – are only available at the national level, but commodity frontier zones are usually subnational units, and sometimes cross national borders.Footnote ³⁴ National data collections remain indispensable, but data collection at the subnational and transregional level is equally important.

While still difficult, an inductive and multi-scalar approach is increasingly feasible thanks to innovative technologies of data gathering, analysis and visualization. Digital humanities techniques let us look at a myriad of sources to illuminate the workings of commodity frontiers at the local level and may release us from over-relying on data aggregated at the national level. Publications on particular commodity frontier zones that span decades and perspectives are already available in digital format, and we can draw on their research findings. Moreover, since frontier zones are marked by the commodification of land and labour, they have been relatively well documented by colonial administrations, revenue records and so on. In recent years archives have been digitizing their holdings of documents, historical artefacts and newspapers. Archaeologists working on the Baltics, Southern Spain and the Eastern Mediterranean, for example, have employed excavations, paleoenvironmental sources and laser techniques that would help us reconstruct even the oldest commodity frontiers.Footnote ³⁵

If these sources can be digitally connected and automated data-mining processes applied to them, it becomes feasible to extract a wide range of data from very disparate sources in different languages. What is more, semantic technology can help us create structured data sets from immense collections of fuzzy data. Analysis of these sources within a global comparative context, enhanced by visual representations such as maps and graphs, can provide clues for new hypotheses to be tested against the assembled corpus of data or even Linked Open Data. These technologies facilitate the integration of geographic knowledge from diverse data sources, and they have been developing rapidly, offering the promise that they will soon become more customer-friendly.Footnote ³⁶

To deliver on the promises of a commodity frontiers centred analysis of global capitalism we need to draw on approaches and disciplines that often stay aloof from one another.Footnote ³⁷ Combining data gathering and analysis techniques with fieldwork will bridge the divide between disciplines that study the past and those that study the present. Global historians need to draw on the methods of ecological economists and other social scientists – on the Environmental Justice Atlas https://ejatlas.org/, for example – to map today’s ecological inequalities. Combining archival research, fieldwork and digital techniques and deploying an inductive methodology at different spatial and time scales will enable us to understand the shifts of key commodity frontiers and the emergence of particular commodity regimes, and thus to redraw our understanding of global capitalism.

Studying the global history of commodity frontiers is crucial to coming to terms with important aspects of world history over the past six centuries. But this project is just as important when it comes to understanding our contemporary dilemmas. Two recent reports commissioned by the European Union recommend that the EU considers its giant global ecological footprint.Footnote ³⁸ These reports – along with international reporting more generally – suggest that we have arrived at a new state of unsustainability. But as alarming as this is, when we look at commodity frontiers over the very long term, we immediately see that our contemporary dilemmas are not new. The consumption of massive amounts of extra-European resources is an old story that goes back at least 600 years and has played a major role in Europe’s economic ascendancy. There is a similar, though shorter story for the USA and other emerging powers that arrange their economies through a mix of domestic production and global trade in commodities that usually originate in the countryside.

To disentangle the complexities that may derail today’s attempts to frame a global agenda of sustainable growth, we have to understand in new historical depth the dynamics of appropriation of nature, enclosures of land, regimes of labour control and transfers of capital and knowledge and the concomitant elimination of ecological and social knowledge. At the same time, global history can deliver on some of its fundamental promises by looking systematically at global change over very long time periods while remaining attentive to history told from the bottom-up. A new global social history will allow us to analyse consecutive commodity regimes and understand the ways they have created unequal power relations and massive inequities that shape the present. Studying commodity frontiers can help us identify historical capitalism as a process rooted in a profound restructuring of rural societies and their relation to nature and lets us connect processes of extraction and exchange with degradation, adaptation and resistance in rural peripheries. When we look at the history of the sixteenth-century sugar frontier or the mid-twentieth-century soy frontier as moments in the unfolding of various commodity regimes over the past six centuries, we gain not just novel perspectives on the history of capitalism, but also on our contemporary dilemmas. Global historians can make a unique contribution to this conversation.
