New study finds genetically engineered crops could play a role in sustainable agriculture

June 08, 2007

(Santa Barbara, California) - Genetically modified (GM) crops may contribute to increased productivity in sustainable agriculture, according to a groundbreaking study published in the June 8 issue of the journal Science. The study analyzes, for the first time, environmental impact data from field experiments all over the world, involving corn and cotton plants with a Bt gene inserted for its insecticidal properties. The research was conducted by scientists at the National Center for Ecological Analysis and Synthesis (NCEAS) at the University of California, Santa Barbara, The Nature Conservancy, and Santa Clara University. The study is accompanied by a searchable global database for agricultural and environmental scientists studying the effects of genetically engineered crops.

Biotechnology and genetic engineering are controversial because of concerns about risks to human health and biodiversity, but few analyses exist that reveal the actual effects genetically modified plants have on other non-modified species. In an analysis of 42 field experiments, scientists found that this particular modification, which causes the plant to produce an insecticide internally, can have an environmental benefit because large-scale insecticide spraying can be avoided. Organisms such as ladybird beetles, earthworms, and bees in locales with "Bt crops" fared better in field trials than those within locales treated with chemical insecticides.

"This is a groundbreaking study and the first of its kind to evaluate the current science surrounding genetically modified crops. The results are significant for how we think about technology and the future of sustainable agriculture," said Peter Kareiva, chief scientist of The Nature Conservancy.

According to lead author, Michele Marvier, of Santa Clara University, "We can now answer the question: Do Bt crops have effects on beneficial insects and worms" The answer is that it depends to a large degree upon the type of comparison one makes. When Bt crops are compared to crops sprayed with insecticides, the Bt crops come out looking quite good. But when Bt crops are compared to crops without insecticides, there are reductions of certain animal groups that warrant further investigation." What is clear is that the advantages or disadvantages of GM crops depend on the specific goals and vision for agroecosystems.

As NCEAS Director, Jim Reichman explains, "This important study by an interdisciplinary research team reveals how an in-depth analysis of large quantities of existing data from many individual experiments can provide a greater understanding of a complex issue. The project is enhanced by the creation of a public database, Nontarget Effects of Bt Crops, developed by NCEAS ecoinformatics expert, Jim Regetz, that will allow other scientists to conduct congruent analyses."

What's So Controversial about Genetically Modified Food? (Food Controversies)

What's So Controversial about Genetically Modified Food? (Food Controversies)
by John T. Lang (Author)


The rampant use of genetically modified food incites fierce and seemingly intractable debates among environmental activists, scientists, government regulators, and representatives of the food and agriculture industries. While some portray GMOs as scientific progress, others frame them as a form of perverted science. But why, exactly, are they so controversial? This timely and balanced book explores the science—and myth—that surrounds genetically modified food in order to help us understand just what’s at stake.
 
John T. Lang begins by grounding the debates in the biology and chemistry behind genetic modification. He then shows how food is deeply imbued with religious, social, cultural, and ethical meanings, which bring a variety of non-scientific issues to the forefront...

GMO Myths and Truths: A Citizen's Guide to the Evidence on the Safety and Efficacy of Genetically Modified Crops and Foods, 3rd Edition
by Claire Robinson Mphil (Author), Michael Antoniou PhD (Author), John Fagan PhD (Author)


It is often claimed that the case against genetically modified (GM) crops and foods is based on emotion, not science, and that to oppose GM crop and food technology is to be anti-science. It is also claimed that GM crops offer higher yields and better nutrition, that they are safe for health and the environment, that they reduce agrochemical use, and that they are needed to feed the world’s growing population. This book, co-authored by two genetic engineers and a writer/researcher, exposes these claims as false, using scientific and other documented evidence. GMO Myths and Truths summarizes the facts on the safety and efficacy of genetically modified (GM) crops and foods in terms that are accessible to the non-scientist but still relevant to scientists, policymakers and educators.

Monsanto—one of the largest agriculture and biotech companies in the world—creates genetically engineered seeds and food, or GMOs. They've also brought us toxic chemicals like DDT, PCBs and even Agent Orange.  But what is Monsanto truly doing to our diet—and why do many consider their business practices deeply abusive? Are GMOs the solution to world hunger, or a shockingly dangerous threat to our health? And does Monsanto really, as some suggest, control much of the United States' agriculture and food departments?  Meticulously researched, Monsanto vs. the World puts to rest the myths and shows the shocking reality, delving into the science of GMOs, the political machinations of Monsanto in Washington and around the world, and showing what you can do to keep GMOs off your...

Seeds for the Future: The Impact of Genetically Modified Crops on the Environment
by Jennifer A. Thomson (Author)


Plants have long been genetically modified through crossbreeding and other basic agricultural techniques to make crops more resilient, nutritious, and profitable. In recent decades, however, advances in genetic engineering―including the ability to blend genetic material from animals with that of plants―have allowed farmers to grow crops that resist insect pests, weeds, viruses, and drought; provide increased iron or beta carotene; deliver vaccines and antibodies; reduce common allergens and pollutants; and augment marketable qualities such as delayed ripening. The complicated scientific, environmental, legal, cultural, and ethical issues surrounding these crops are being hotly debated all over the world. In Seeds for the Future, an internationally respected molecular geneticist and...
