Cereal grains like wheat and rice are important, because they are the basis of most food supplies. Yields of such crops have increased dramatically during the past 100 years and especially since 1950, leading to what was often called the Green Revolution. This book examines why the United States, India, Britain and Mexico each sought to develop high yield wheat production. Although the increase in yield has been attributed to plant breeding science, security concerns and management of foreign exchange were prime motivators of the new technologies. This relationship has not been previously developed in studies of agricultural modernization, and will plague future efforts to make agriculture equitable and sustainable.

During the last 100 years, the worldwide yields of cereal grains, such as wheat and rice, have increased dramatically. Since the 1950s, developments in plant breeding science have been heralded as a "Green Revolution" in modern agriculture. But what factors have enabled and promoted these technical changes? And what are the implications for the future of agriculture? This new book uses a framework of political ecology and environmental history to explore the "Green Revolution''s" emergence during the 20th century in the United States, Mexico, India, and Britain. It argues that the national security planning efforts of each nation were the most important forces promoting the development and spread of the "Green Revolution"; when viewed in the larger scheme, this period can be seen as the latest chapter in the long history of wheat use among humans, which dates back to the neolithic revolution. Efforts to reform agriculture and mitigate some of the harsh environmental and social consequences of the "Green Revolution" have generally been insensitive to the deeply embedded nature of high yielding agriculture in human ecology and political affairs. This important insight challenges those involved in agriculture reform to make productivity both sustainable and adequate for a growing human population.

The field of pest control research, of increasing importance in a world short of food, has been plagued for many years by a variety of problems, among them (1) the instability (including pesticide resistance) of many control techniques, (2) the continuing need for improved pest management methods to increase world food supplies, and (3) the environmental and social hazards of currently used pesticides. What historical or other factors affect the ability of science to generate useful new technologies to alleviate these three major problems? Are there barriers to cooperation among the different pest control specialists? This book attempts to answer these questions, examining past events and projecting likely impacts on contemporary pest management systems. The authors--sociologists, economists, lawyers, ecologists, political scientists, and pest control scientists--examine the social, economic, political, and ethical factors that are important in shaping pest management systems, as well as developmental patterns that show the importance of these factors in shaping today's systems.

Changing Energy outlines how humanity came to its current energy economy through three previous energy transitions and now stands poised for a necessary fourth one. Despite the immense benefits conferred by a global energy economy based primarily on coal, oil, gas, and uranium, societies must now rebuild their energy economies to rely as much as possible on renewable energy used efficiently. This imperative to change comes from the risks of climate change plus the dangers of geopolitical tensions, health and environmental effects, and the long-term prospects for ever depleting sources of today's energy sources. Changing Energy argues that sustainability of the benefits from energy services will come from investments made in the technologies of the fourth transition. Perkins envisions a viable post-fossil fuel energy economy and outlines the barriers that must be resolved to reach it.

Changing Energy outlines how humanity established the current energy economy through three previous transitions, and how we now stand poised for a necessary fourth transition. Human societies around the globe have received immense benefits from uses of coal, oil, gas, and uranium sources, yet we must now rebuild our energy economies to rely on renewable sources and use them efficiently. The imperative for a fourth energy transition comes from dangers related to climate change, geopolitical tensions, documented health and environmental effects, and long-term depletion of today’s sources. John H. Perkins argues that a future in which current levels of energy service benefits are sustained can come only from investments in the technologies needed to bring about a fourth energy transition. Changing Energy envisions a viable post–fossil fuel economy and identifies the barriers to be overcome.

Science and technology are cultural phenomena. Expert knowledge is generated amid the conflicts of a society and in turn supplies fuel to fire yet further change and new clashes. This essay on economic entomology is a case study on how cultural events and forces affected the creation of scientific and technical knowledge. The time period emphasized is 1945 to 1980. My initial premises for selecting relevant data for the story were ultimately not of much use. Virtually all debates about insect control since 1945 have been centered around the environmental and health hazards associated with insecticides. My first but inadequate conclusion was that the center of interest lay between those who defended the chemicals and those who advocated the use of nonchemical control methods. With this formulation of the problem, I was drawn to an analysis of how the chemical manufacturers had managed to dominate and even corrupt the work of entomological scientists, farmers, members of Congress, and regulators in the USDA and EPA. My own contribu tions to a policy study at the National Academy of Sciences were based 1 on this premise. More recently, Robert van den Bosch developed the 2 "corruption theme" in considerable detail.
