Labor History

Latin American labor has a well-established historiography, in dialogue with trends outside of the region. Environmental history is a newer and more exploratory field. In basic terms, environmental history explores the relationships of humans with the natural world, sometimes referred to as “nonhuman nature.” This can include how humans have affected the natural world, how the natural world has affected human history, and histories of human ideas and belief systems about nature. Labor and environmental history grows from explorations of the connections between these two spheres. Humans interact with the natural world through their labor and from their class perspective. The natural world shapes the work that people do and the institutions and structures humans create to organize and control labor. Changing labor regimes change the ways that humans interact with, and think about, the natural world. Both labor and environmental histories are in some senses investigations of how humans relate to nature. This essay sets Latin American labor and environmental history in global historical context. After offering a chronological summary, it briefly examines connections between U.S. Latino and Latin American labor and environmental histories, and ends with a discussion of contemporary Latin American critical environmentalisms.

From the time that Columbus arrived in the Caribbean until Spain surrendered power over its mainland American colonies in the early 19th century, Spanish and Portuguese colonial mines poured forth vast amounts of bullion, including some gold and a far greater quantity of silver, both in terms of weight and its overall value relative to gold. Fiscal records indicate that Spanish Americans officially refined gold worth approximately 374,000,000 pesos, each consisting of 272 maravedís, whereas the amount of silver produced reached a value of 3,432,000,000 pesos (to these figures need to be added contraband output, estimated to have been around 17–20 percent). In other words, the colonies refined nine times more silver than gold. While Columbus, Cortés, and other earlier explorers may have fantasized primarily about gold, it was the flood of American silver that touched off the price revolution in Europe and monetarized the emerging world economy, especially because China had a voracious appetite for silver, not gold. At the same time in the American colonies, mining distorted economic life because of the incentives the industry received from a silver-hungry monarchy. Mining also had profound consequences for indigenous society, severely exploited to provide workers for the mines and refining mills.

Colonial refiners used two methods to beneficiate their silver ores, smelting and amalgamation. Smelting was suitable for all types of American silver ores but required large amounts of fuel to heat the ovens. It remained widely used throughout Mexico during the entire colonial period. Amalgamation was a newer technology, adapted to American ores during the mid-16th century. Although it did not require large quantities of charcoal and other fuels, as smelting did, amalgamation depended on the availability of mercury. Nearly all quicksilver used in colonial Spanish American silver mining came from either Huancavelica (Peru) or Almadén (Spain), with occasional supplements from Idria (Slovenia). Whereas both smelting and amalgamation were used widely in Mexico, Andean mines relied on amalgamation.

Before there was Mexico, there was oil. Millennia of organic matter that collapsed and liquefied into fossil fuel rested deep underground and underwater along the half-moon territorial formation that 19th-century geographers named the Mexican Gulf. Hidden by the lush tropical rainforests, marshes, and mangroves that occupied the landscape from the Pánuco River on the border between modern day Tamaulipas and Veracruz and the Bay of Campeche on the South, the oil seeped to the surface in small ponds, sometimes blackening the waters of streams and lagoons from Tabasco to the Huasteca. The human communities who inhabited that part of the globe thousands of years later knew about and utilized nature’s oozing sticky black tar.

The Olmec, who flourished in southern Veracruz from 1200 to 400 bce, collected the viscous liquid. They used it to seal canoes and aqueducts, to paint and decorate clay figurines and knife handles, to pave the floors of their homes, and to glue materials. There is evidence they boiled and cooked the petroleum for better usage, a process that would become known as refining in the 19th century. At the northern end of the rainforest, the region called the Huasteca, the Teenek also gathered the syrupy fluid from its natural springs into the 15th century and used it in ways similar to the Olmec of yesteryear: as sealant for canoes, paint for pottery, perfume, gum for chewing and teeth cleaning, illuminant for torches, and aromatic incense for religious ceremonies. Yet it was the Aztec who gave petroleum the native name that survives to this day, chapopote, the hispanicized version of tzaucpopochtli, meaning fragrant (popochtli) glue (tzauctli). As humans did globally, those who lived with chapopoteras utilized what nature created and transformed it according to their cultural needs and inventions. There is no evidence that anyone living along the coastal range of the Gulf of Mexico in the pre-Columbian era went beyond collecting the oil that percolated from the subsoil naturally. In other words, there is no evidence of extraction of petroleum by indigenous people. Oil extraction, and its environmental consequences, is a 20th-century story, layered over a 15th-century ecological revolution.

For the greater part of the 19th and 20th centuries, Cuba, the largest island in the Antilles, figured as the principal exporter of sugar cane, a product that dominated the country’s agro-industry. In this way, Cuba became illustrative of the economic, social, political, and environmental impact of basing an economy on monoculture in order to supply foreign markets. This does not mean, however, that sugar cane was the only major crop being grown in the Cuban fields, as there was no dearth of different plants destined for foreign markets, such as tobacco and coffee, or for local markets, such as yucca, plantains, corn, sweet potatoes, and rice, not to mention a long if little-known livestock tradition. However, the dominance of agro-industry almost always eclipses agricultural and economic alternatives that could become potential competitors, despite the periodic adverse circumstances that affect consumers. But, in the 1990s, the production and exportation of sugar suffered an abrupt fall, creating a vacuum that allowed diversification of land use and that prompted a search for alternative agricultural models.

Aridity, a significant characteristic of the U.S.–Mexico borderlands, has affected water use patterns for different groups of people in this region for thousands of years. From indigenous groups to European invaders and colonizers to 20th- and 21st-century farmers, ranchers, and policy-makers in Mexico and the United States, controlling the area’s scarce water resources has been a vital concern for survival and economic success. Given that an international border divides the region, national-era relations between the United States and Mexico often have been marked by water issues and the development of water projects and policies. And on both sides of the border these projects and policies have caused environmental changes that merit attention. Much of that history revolves around agricultural development with the need to ensure steady sources of water for irrigation. But industry and urban areas have also been enormous consumers of scarce water resources in the region, issues that are discussed here.
