American agriculture in the twentieth century has given the world one of its great success stories, a paradigm of productivity and plenty. Yet the story has its dark side, from the plight of the Okies in the 1930s to the farm crisis of the 1980s to today's concerns about low crop prices and the impact of biotechnology. Looking at U.S. farming over the past century, Bruce Gardner searches out explanations for both the remarkable progress and the persistent social problems that have marked the history of American agriculture.

Gardner documents both the economic difficulties that have confronted farmers and the technological and economic transformations that have lifted them from relative poverty to economic parity with the nonfarm population. He provides a detailed analysis of the causes of these trends, with emphasis on the role of government action. He reviews how commodity support programs, driven by interest-group politics, have spent hundreds of billions of dollars to little purpose. Nonetheless, Gardner concludes that by reconciling competing economic interests while fostering productivity growth and economic integration of the farm and nonfarm economies, the overall twentieth-century role of government in American agriculture is fairly viewed as a triumph of democracy.

Recent agricultural reforms in the People's Republic of China have generated great interest in the ability of the Chinese state, traditional and modern, to accommodate rapid economic change. Exhausting the Earth examines an earlier period—from the late Ming to the mid-Qing era marked by tremendous population growth, extension of the market, and increases in agricultural productivity.

Peter C. Perdue describes the relationship between agricultural production and state policies toward taxation, land clearance, dike-building; property rights, and agriculture in Hunan. During the late seventeenth and early eighteenth centuries, Hunan changed from a peripheral, sparsely populated region into a crowded, highly commercialized, grain-exporting province. State policies had stimulated this growth, but by the early nineteenth century serious signs of overpopulation, social conflict, and ecological exhaustion had surfaced. Local officials were conscious of these dangers, but the influence of the state on the economy was so weakened that they could not alter the ominous trends. The stage was set for the disintegration and rebellion of the nineteenth century. This in-depth study of official policies in one region over a long stretch of time illuminates the dynamics of official initiatives and local response.
