Issue Papers - IP49 - February 2012

Herbicides were developed during the twentieth century to be used with conventional tillage for weed control. Conservation (or minimum) tillage subsequently evolved, which enabled less soil damage when used with herbicides. Selection pressure, however, has resulted in weed species that have made adaptations for survival in conjunction with tillage. The U.S. government has put several federal policies and programs in place that help determine the selection and implementation of crops and conservation programs in relation to herbicides and tillage. This Issue Paper (IP 49) examines the impact of certain weed management practices on soil conservation objectives and addresses ways to mitigate negative effects. Chair: David R. Shaw, Office of Research and Economic Development, Mississippi State University, Mississippi State. IP49, February 2012, 16 pp. FREE. Available online and in print (fee for shipping/handling).

 
 
Issue Papers - IP48 - January 2012

Energy Issues Affecting Corn/Soybean Systems: Challenges for Sustainable Production speaks to energy issues within the corn/soybean production system as a model for understanding the complexity of addressing global energy challenges. Research and development is needed to find ways to lower adoption barriers for energy-conserving practices and develop management systems that allow agricultural production to meet multiple demands. The challenges include (1) a growth in biofuel production directly from corn/soybeans coupled with a simultaneous growth in oil and agricultural commodity prices, and (2) the ability of the motor fuel infrastructure to handle an increased volume of ethanol, biodiesel, and advanced biofuels. The authors propose a landscape vision for sustainable corn/soybean systems that is feasible and could be done efficiently and economically if there is a desire and public willingness to do so. It would, among other things, provide sustainable grain and biomass feedstock supplies for the bioenergy industry, protect water quality, lessen producer/environmental risk, and promote biodiversity.

Task Force Reports - R142 - October 2011

The need to decrease concentrations of carbon dioxide and other greenhouse gases (GHGs) in Earth's atmosphere has been identified as one of the most pressing modern-day environmental issues. Agriculture, in addition to being affected by the climate, contributes to climate change through its exchanges of GHGs with the atmosphere. This report provides up-to-date information on the science of carbon sequestration and GHG mitigation for various sectors of U.S. agriculture, including logistical and economic considerations for implementing practices designed to decrease GHG emissions from agriculture. The report draws on elements of the related 2004 CAST Task Force Report, Climate Change and Greenhouse Gas Mitigation: Challenges and Opportunities for Agriculture. Cochairs: Ron Follett, USDA-ARS-NPA; Sian Mooney, Boise State University; Jack Morgan, USDA-ARS-NPA; Keith Paustian, Colorado State University.

CAST Commentaries - QTA2011-2 - June 2011

Humans and animals have been consuming genetically engineered (GE) food from plants for decades, but the recent approval of GE salmon intended as human food has resulted in debate and some controversy. Many still have concerns about the environmental impact and food safety issues of such an approval. More research is needed as policymakers struggle with laws ranging from the approval of GE procedures to the labeling of such food in the markets. This Commentary looks at how GE animals are currently regulated and what type of data is needed to demonstrate the safety of GE organisms. The authors also look at the opportunities for public participation in the regulatory process and the implications for the future of this technology.  Chair: Dr. Alison Van Eenennaam, University of California-Davis. QTA2011-2, 8pp., June 2011. AVAILABLE ONLINE ONLY.

Issue Papers - IP47 - May 2011

The purpose of this CAST Issue Paper (IP 47) is to go beyond the generalizations and accusations often associated with the air quality topic. Experts from six universities examine a large amount of data and focus their information and conclusions around the key livestock areas: swine, poultry, dairy, and beef. Their critical analyses look at a wide scope of issues, from greenhouse gas emissions to the logistics of manure storage facilities. The U.S. Environmental Protection Agency is increasing efforts to monitor emissions from agriculture, so further research is important for all parties involved, and this paper provides solid, science-based information. Chair: Larry D. Jacobson, Department of Bioproducts and Biosystems Engineering, University of Minnesota, St. Paul. IP47, May 2011, 24 pp. FREE.

CAST Commentaries - QTA2011-1 - March 2011

Everyone is concerned with return on investment, and agricultural research continues to be an example of the positive impact well-placed funding can have.  Agriculture is a key to the nation's economy, and research not only boosts that industry, it also promotes solutions for many of the country's pressing problems in the areas of health, energy, environment, rural development, trade, and food safety.  This Commentary is directed to the Congress (for funding), the Administration (for initiatives), and the public (for insight). Recognized scholars provide an assessment of the high "rate of return" agricultural research has delivered to the American and global public and why funding is truly in the public interest. As the authors point out, "Plans for a better future start today."  Chair: Dr. Wallace Huffman, Iowa State University, Ames. QTA2011-1, 12pp., March 2011. AVAILABLE ONLINE ONLY.

 
 
CAST Commentaries - QTA2010-1 - September 2010

A panel of experts has outlined key issues regarding biomass crops by examining the harvest, transportation, and storage of cellulosic material. Task Force Chair Jerry Fruin indicates that successful biomass feedstock production depends on the smooth blending of successful approaches to these three logistical necessities. Citing a number of research activities aimed at providing solutions to specific processes within the feedstock chain, they look at biomass collection, storage, and costs, and then highlight results from studies regarding switchgrass and corncobs. Chair: Dr. Jerry Fruin, Department of Applied Economics, University of Minnesota, St. Paul. QTA2010-1, 8pp., September 2010. AVAILABLE ONLINE ONLY.

Thirty-two presenters, speaking individually or as panelists, addressed the topic of Sustaining Animal Agriculture: Balancing Bioethical, Economic, and Social Issues.

Approximately 250 people from a wide variety of organizations attended the symposium, which was held in the Jefferson Auditorium at the USDA's South Building. Attendees had the opportunity to interact with presenters during several Q&A sessions throughout the meeting.

Critical issues addressed during the symposium included
• bioethical and animal welfare issues,
• analysis of certification and regulatory programs,
• integration of competing concepts surrounding the ethical use of food animals,
• long-term survival and food security,
• societal and global impacts, and
• consequences of decisions by consumer and government decision makers.
