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.
