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...

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...

"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...

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...
