Pest Control: Cultural And Environmental Aspects (Paperback): David Pimentel, John H. Perkins Pest Control: Cultural And Environmental Aspects (Paperback)
David Pimentel, John H. Perkins
R1,236 Discovery Miles 12 360 Ships in 12 - 17 working days

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.

Insects, Experts, and the Insecticide Crisis - The Quest for New Pest Management Strategies (Paperback, Softcover reprint of... Insects, Experts, and the Insecticide Crisis - The Quest for New Pest Management Strategies (Paperback, Softcover reprint of the original 1st ed. 1982)

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."

Changing Energy - The Transition to a Sustainable Future (Paperback): John H. Perkins Changing Energy - The Transition to a Sustainable Future (Paperback)
John H. Perkins
R773 R723 Discovery Miles 7 230 Save R50 (6%) Ships in 9 - 15 working days

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.

Geopolitics and the Green Revolution - Wheat, Genes, and the Cold War (Hardcover, New): John H. Perkins Geopolitics and the Green Revolution - Wheat, Genes, and the Cold War (Hardcover, New)
John H. Perkins
R4,758 Discovery Miles 47 580 Ships in 10 - 15 working days

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.
