Agrarian reforms transformed the Mexican countryside in the late twentieth century but without, in many cases, altering fundamental power relationships. This study of the Tehuacán Valley in the state of Puebla highlights different strategies to manipulate the local implementation of federal government programs. With their very differing successes in the struggle to regain and maintain control of land and water rights, these strategies raise important questions about the meaning of the phrase "locally controlled development."

Because Mexico is dependent on irrigation for 45 percent of its cash crop production, national policy has focused on developing vast government controlled and financed irrigation systems. In the Tehuacán Valley, however, the inhabitants have developed a complex irrigation system without government aid or supervision. Yet, in contrast to most parts of Mexico, water rights can be bought and sold as a commodity, leading to accumulation, stratification, and emergence of a regional elite whose power is based on ownership of land and water. The analysis provides an important contribution to the understanding of local control.

The findings of this study will be important to a wide audience involved in the study of irrigation, local agricultural systems, and the interplay between local power structures and the national government in developing countries. The book also presents unique material on gravity-fed, horizontal wells, known as qanat in the Middle East, which had been unknown in the literature on Latin America before this book.

International migration between countries in Latin America became increasingly important during the twentieth century, but for a long time it was the subject of only limited research. Scott Whiteford sets the Argentina-Bolivia experience in historical perspective by examining the macrolevel factors that influenced social change in both countries and brought streams of migration into Argentina. Seasonal labor, the expansion of capitalist agriculture, international migration, and urbanization are central topics in this in-depth study of Bolivian migrants in Northwest Argentina.

Whiteford’s vivid portrayal of the lives and working conditions of the migrants is based on two years of research during which he lived with the workers on a sugar plantation and, after the harvest, accompanied them to other farms and to the city of Salta in their search for more work. He traces the development of plantation agriculture in Northwest Argentina and the processes by which the plantation gained access to cheap labor and maintained control over it.

As Bolivians migrated to Argentina in ever greater numbers, many recruited for the harvest remained. Whiteford’s analysis of the diverse strategies employed by workers and their families to support themselves during the post-harvest season is a major contribution to migration literature. The four distinct but related patterns of migration that he describes created a labor reserve that transcends rural/urban designations, one that is utilized by employers in both the countryside and the city.
