Along with petroleum and grains, oilseeds shifted how Mexico produced and consumed energy in the Green Revolution. After three decades of revolution, rebellion, and reform from 1910 to 1940, the agricultural transformation of oilseeds in the Pacific did more than shape power in Mexico: it made power. During World War II (1941–1945), oilseed agriculture fed people and the economy. Oilseed development might have been most prominent on the Pacific coasts of Mexico but it was not on the margins of the Green Revolution. Oilseed industries were central to postwar development from Sonora to Chiapas. This analysis resituates Mexico’s Pacific Coast within global agro-business networks. After analyzing how oilseed industries are prejudicial against oilseed farmers, this chapter details the expansion of oilseed agriculture and development during the coconut booms of the 1940s and 1950s, arguing that oilseed-producing zones experienced ecological realities and violence, such as chemical and technology-intensive agriculture, especially from agrochemicals.
