The process of nation-building in Latin America transformed the relations between the state, the economy, and nature. Between 1760 and 1940, the economies of most countries in the Spanish Caribbean came to depend heavily on the export of plant products, such as coffee, tobacco, and sugar. After the mid-nineteenth century, this model of export-led economic growth also became a central tenet of liberal projects of nation-building. As international competition grew and commodity prices fell over this period, Latin American growers strove to remain competitive by increasing agricultural production. By the turn of the twentieth century, their pursuit of export-led growth had generated severe environmental problems, including soil exhaustion, erosion, and epidemic outbreaks of crop diseases and pests.
