Geopolitics and the Green Revolution

Wheat, Genes, and the Cold War

By: John H. Perkins

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 thesetechnical 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 thenational 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 theneolithic 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 insightchallenges those involved in agriculture reform to make productivity both sustainable and adequate for a growing human population.

Catalysis

Science and Technology

By: John R. Anderson,Michel Boudart

The development of a commercially successful process for the catalytic synthesis of ammonia was a scientific as well as a technical triumph. Its implications were con siderable. It demonstrated the power of a combination of innovative technology and engineering together with basic chemical science, and it introduced ideas and techniques into catalytic science and process engineering which are still with us today. In a real sense, this process changed the face of industrial chemistry and process technology. Of course, the key step in the direct synthesis of ammonia was the development of an efficient catalyst, and the historical account given by Dr. S. A. Topham in the first chapter of this volume shows how this was success fully accomplished, and how this was combined with the successful solution of other daunting technical problems to make the overall process possible. The microstructure of a catalyst is an important feature which determines its behaviour, and the electron microscope is one of the most important instrumental methods by means of which structural and microstruc tural information can be obtained. Nevertheless, the elec tron-optical processes of image formation are complex, but need to be properly understood if image interpreta tion is to be done reliably. In the second chapter of this volume, Dr. J. V. Sanders addresses the entire field of the application of electron microscopic methods to the examination of catalysts.
