Biofuels and food are dependent on the same resources for production: land, water, and energy. The conjuncture of food, energy, and climate crises demands a new direction in how to harness agriculture to the joint tasks of energy-saving, emissions reduction, and food security.
David Pimentel is an American professor of insect ecology and agricultural sciences at Cornell University in Ithaca, New York.
Background
David Pimentel was born on May 24, 1925 in Fresno, California, United States. His parents, Frank Freitas and Marion Silva Pimentel, were farmers raising vegetables and grapes. At age six, Pimentel moved with his family to a farm in Middleborough, Massachusetts.
Education
David Pimentel attended St. John’s University in Collegeville in 1943 and Clark University in 1946. In 1948 David received a Bachelor of Science at the University of Massachusetts. Pimentel earned a Doctor of Philosophy at Cornell University in 1951.
Pimentel’s scientific career gained an auspicious start when his undergraduate research was published in 1949. Still a member of the Air Force Reserve, Pimentel was called back into active duty after receiving his Ph.D. Pimentel no longer desired a flying career and obtained a transfer into the U.S. Public Health Service (USPHS). He served as chief of the Tropical Research Laboratory in San Juan, Puerto Rico, from 1951 to 1955. Research there primarily focused on mongooses — important in the transmission of rabies — and snails, which contributed to the spread of other major diseases. From 1954 to 1955 Pimentel spent spring and summer in Savannah, Georgia, as project leader at the USPHS Technical Development Laboratory. During winters, Pimentel engaged in postdoctoral insect ecology research at the University of Chicago, Illinois.
Pimentel joined the faculty of Cornell University in 1955 as assistant professor of insect ecology. He has remained there for the duration of his career, becoming a full professor and chairman of the department of entomology and limnology in 1963. Pimentel’s research broadened over the course of his career. Pimentel has authored over four hundred publications, including seventeen books. One of the most important is a 1973 paper that reported the first-ever measurements of energy use in food production. It appeared at the height of the energy crisis in the 1970s. Other landmark publications include several articles related to reduction of pesticide use and a 1963 paper that led to new methods of selecting pest control agents.
Pimentel’s expertise in environmental research led to his participation in numerous national and international committees. Among the most notable was the President’s Science Advisory Council of 1964-66. The council assembled basic research information on a wide range of environmental pollution issues into a major report used in policy development. Also significant was a 1969 commission on pesticides that recommended the banning of DDT and that led to the formation of the Environmental Protection Agency. Serving more than sixteen years as an elected member of the Ithaca, New York, mayor’s council, Pimentel has been active in the administration of local affairs, such as road repairs and the town budget. Currently, he lives in Ithaca with his wife.
Achievements
David Pimentel was highly famous as the author of books Genetics and Ecology of Population Control, Pesticides: Contemporary Roles in Agriculture, Health, and Environment, and Food, Energy, and Society. A widely recognized authority on ecologically sound methods of pest control, sustainable agriculture, and the relationship between human populations and environmental impacts, Pimentel has played a central role in national and international environmental policies. Pimentel’s former students have become major players in research and environmental policy making throughout the world. His accomplishments have attracted many honors, including the 1992 Award for Distinguished Service to Rural Life.
