Environmental Safety of Genetically Engineered Crops

Rebecca Grumet

Michigan State University Press, 2010

Since the mid-1990s, when the technology was first introduced, the cultivation of genetically engineered (GE) crops has grown exponentially. In the U.S. alone, adoption rates for transgenic cotton, corn, and soybeans are between 70–90%. Across the globe, 14 million farmers grow GE crops in more than twenty countries. Yet many countries are discussing and debating the use and adoption of GE technology because of concerns about their impact on the environment and human health. Now, in this comprehensive handbook, a team of international experts present the scientific basis for GE crops, placing them in the context of current agricultural systems, and examining the potential environmental risks posed by their deployment. An integrated approach to an increasingly hot and globally debated topic, the book considers the past, present, and future of GE crops, and offers an invaluable perspective for regulation and policy development.

Genetic Improvement of Crops

Emergent Techniques

Irwin Rubenstein

University of Minnesota Press, 1980

Genetic Improvement of Crops was first published in 1980. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.Recent years have seen the emergence of a number of in vitro techniques that hold promise for the genetic alteration of higher organisms by non-traditional means. These new techniques may eventually modify the genetic structure of cash crop plants and, in practical terms, may lead to substantial improvement of crop production and to disease resistance in plants.This volume brings together 10 research reports by scientists actively engaged in developing genetic techniques in plants and other organisms. The first section explores both the potential for application of these techniques and the genetic needs of plant breeders. Other sections deal with genome organization and function; recombinant DNA technology and application; gene transfer; organelle transfer; and plant tissue culture.

The Great Maya Droughts in Cultural Context

Case Studies in Resilience and Vulnerability

Gyles Iannone

University Press of Colorado, 2014

In The Great Maya Droughts in Cultural Context, contributors reject the popularized link between societal collapse and drought in Maya civilization, arguing that a series of periodic “collapses,” including the infamous Terminal Classic collapse (AD 750–1050), were not caused solely by climate change–related droughts but by a combination of other social, political, and environmental factors. New and senior scholars of archaeology and environmental science explore the timing and intensity of droughts and provide a nuanced understanding of socio-ecological dynamics, with specific reference to what makes communities resilient or vulnerable when faced with environmental change.Contributors recognize the existence of four droughts that correlate with periods of demographic and political decline and identify a variety of concurrent political and social issues. They argue that these primary underlying factors were exacerbated by drought conditions and ultimately led to societal transitions that were by no means uniform across various sites and subregions. They also deconstruct the concept of “collapse” itself—although the line of Maya kings ended with the Terminal Classic collapse, the Maya people and their civilization survived.

The Great Maya Droughts in Cultural Context offers new insights into the complicated series of events that impacted the decline of Maya civilization. This significant contribution to our increasingly comprehensive understanding of ancient Maya culture will be of interest to students and scholars of archaeology, anthropology, geography, and environmental studies.

So Shall You Reap

Farming And Crops In Human Affairs

Otto T. Solbrig and Dorothy J. Solbrig

Island Press, 1994

So Shall You Reap is a broad-gauged exploration of the intersections of farming and history. Beginning with the prehistorical era, Otto and Dorothy Solbrig describe the evolution of farming. When and how did people learn to irrigate, to fertilize, to rotate their crops -- and why?

Along with its fundamental importance to history, farming has radically altered the physical world. Natural landscapes have been completely transformed to provide room for growth on a large scale of a few species of plants and even fewer species of domesticated animals. Agriculture has altered the earth's biosphere and changed its geosphere: The soil has been modified, forests have been felled, swamps have been drained, rivers have been dammed and diverted.

So Shall You Reap presents a fresh and informed perspective on how farming and the crops we grow have changed us and our environment. By understanding the nature of the origins and evolution of agriculture, we will be better prepared to anticipate what the future may hold in store, and what must be done to increase food production while minimizing environmental problems.

Starved for Science

How Biotechnology Is Being Kept Out of Africa

Robert PaarlbergForeword by Norman Borlaug and Jimmy Carter

Harvard University Press, 2009

Listen to a short interview with Robert PaarlbergHost: Chris Gondek | Producer: Heron & Crane

Heading upcountry in Africa to visit small farms is absolutely exhilarating given the dramatic beauty of big skies, red soil, and arid vistas, but eventually the two-lane tarmac narrows to rutted dirt, and the journey must continue on foot. The farmers you eventually meet are mostly women, hardworking but visibly poor. They have no improved seeds, no chemical fertilizers, no irrigation, and with their meager crops they earn less than a dollar a day. Many are malnourished.

Nearly two-thirds of Africans are employed in agriculture, yet on a per-capita basis they produce roughly 20 percent less than they did in 1970. Although modern agricultural science was the key to reducing rural poverty in Asia, modern farm science—including biotechnology—has recently been kept out of Africa.

In Starved for Science Robert Paarlberg explains why poor African farmers are denied access to productive technologies, particularly genetically engineered seeds with improved resistance to insects and drought. He traces this obstacle to the current opposition to farm science in prosperous countries. Having embraced agricultural science to become well-fed themselves, those in wealthy countries are now instructing Africans—on the most dubious grounds—not to do the same.

In a book sure to generate intense debate, Paarlberg details how this cultural turn against agricultural science among affluent societies is now being exported, inappropriately, to Africa. Those who are opposed to the use of agricultural technologies are telling African farmers that, in effect, it would be just as well for them to remain poor.
