The commodity frontiers framework describes well the movement of sugar cultivation across the Mediterranean, Atlantic, and Caribbean. But it is less effective when explaining the evolution of sugar in nineteenth-century Tamil Nadu. In Tamil Nadu, the high costs of cultivation discouraged many peasants and landowners from planting sugar cane. As a consequence, despite British pressure to plant more cane, there was little increase in the crop before the twentieth century. In Tamil Nadu, sugar made from palmyra juice was a viable and popular substitute for cane sugar and this further discouraged the expansion of cane cultivation. The jaggery made from palm juice satisfied the demand for sweetener from most consumers in the region. From the mid-nineteenth century, palm jaggery was the raw material for making white sugar and distilling arrack in the sugar mills that were built in the region. Regional conditions shaped the development of sugar cultivation and manufacturing in Tamil Nadu. It is not a story of interaction between the local and the global as is found in the commodity frontiers framework. The region is a scale of activity that possesses great explanatory power, as the case of nineteenth-century South India shows.

This article contributes to the understanding of the scales of global capitalism by addressing labour relations from a historical perspective. Firstly, it suggests that the problem of the deadly cost of the expansion and shifting of commodity frontiers can be resolved only with an approach that scrutinizes humans’ consumption habits and lifestyles. Secondly, it proposes to explore the making of commodity frontiers through the respective sites of immobilization as well as workers’ means of escaping such immobilization. Thirdly, it explores the nexus of health, food, and labour by considering the agricultural production of commodities as toxic frontiers against which workers’ unions have historically organized to protect their safety. Finally, it sheds light on the ways in which the global scale of capitalism has met the micro scale of particles owing to the toxicity of twenty-first-century commodity frontiers.

The World of Sugar, Ulbe Bosma’s compelling historical narrative on how sugar became a global commodity, and the accompanying introductory article in the International Review of Social History raise many fascinating points for further reflection and debate. In this commentary, I wish to highlight several points that resonate strongly with my own work at the Transnational Institute (TNI), a global think tank based in Amsterdam that connects social movements with academics and policymakers. These points of reflection are informed by TNI’s mission and practice of “scholar-activism”: the fact that we seek not only to interpret the world, but also to change it for the better, in particular for those exploited and oppressed classes and social groups. As my work principally involves collaboration with transnational agrarian movements, I pay particular attention to areas of Bosma’s analysis that carry implications for rural working people and for agrarian and environmental justice. This includes the role of sugar in the global land rush, the rise of sugar cane as a “flex crop and commodity”, and the ways in which “rural sugars” can be supported in peasant- and smallholder-based economies and livelihood strategies.
