News media has a tendency to portray certain aspects of agricultural production either positively or negatively. Doug Powell, an associate professor of food safety at Kansas State University co-authored a paper on “Coverage of organic agriculture in North American newspapers: Media – linking food safety, the environment, human health and organic agriculture,” just published in the British Food Journal.

Powell examined how organic food production is portrayed in the media. The paper is based on a study Powell conducted from 1999-2004 with two colleagues at the University of Guelph in Canada, Stacey Cahill and Katija Morley. Cahill was one of Powell’s students at the time. The team explored how topics of organic food and agriculture were discussed in five North American newspapers. Using the content analysis technique, the 618 articles collected were analyzed for topic, tone and theme regarding food safety, environmental concerns and human health. Read the rest of this entry »

An interesting news release from Europe came across my desk.  A group of farmers from Spain, Portugal and Romania traveled to Brussels, Belgium to convey to the European Commission that they are upset that they can not us genetically modified (GM) crops.  They urged that laws be passed to enable them to plant GM crops!

The press release follows with a link to the full report in Spanish.

Brussels, Belgium, July 13, 2010 — Farmers from Spain, Romania and Portugal presented to the members of the parliament (MPs) and representatives of the European Commission (EC) in Brussels a manifesto stating that “Biotechnology, a Tool for Agro-Food cannot be Ignored”. The manifesto points out that the rejection (by the EC) of positions and decisions about GM crops are not based in science. The report goes on to underscore that the safety of GM crops is guaranteed by the strictest and independent scientific assessment. Read the rest of this entry »

Several high profile undercover videos of animal abuse on dairy farms have increased the pressure to implement welfare guidelines, much like the United Egg Producers’ certification program. We’re all appalled with what we have seen in some videos, and it makes it easy to assume that such a system is a terrific idea. Count me unconvinced for a host of reasons, not the least of which is that it will make dairy farms MORE likely to be targeted by animal rights groups. Let’s review how the United Egg Producer program worked for Quality Eggs of New England: Read the rest of this entry »

Conventional wisdom maintains that large family farms are the future of the dairy industry. A 2003 Cornell University study used historical dairy industry data to project the future structure of the US dairy industry and concluded that the number of farms with fewer than 100 cows would decline by 92% from the year 2000 to the year 2020. The conclusion from many when they see such projections is that small farms are a thing of the past and that milk will be produced predominately on large family dairy farms in the future. I believe that is likely to prove incorrect and that we may witness the end of the large family dairy era. Read the rest of this entry »

Proponents of organic foods have touted many health, nutrition and safety benefits associated with the consumption of these foods.  However, credible science does not support the health, nutrition or safety claims made by the organic food industry (see Science Behind Reported Benefits of Organic Milk).  As might be expected, this has been vigorously disputed by advocates of organic food.  This is not a surprise given that deceptive use of marketing and health claims has been a core component of some campaigns to grow market share in the organic food sector.  Thus, some consumers are purchasing organic food on the belief that they are healthier than conventionally produced food.

It is clear that deforestation of the tropical forests damages the environment and forest communities.  A recent report “Farms Here, Forests There:  Tropical Deforestation and U.S. Competitiveness in Agriculture and Timber” discusses the evidence that ending deforestation will increase income for U.S. farmers.  The Report is an interesting read–below is the Executive Summary.

Reader of my blog appreciate that I have been engaged in an effort to increase public understanding about science in society, and the need for biotechnology to be a key part of future solutions to feed the world.  An integral part of this communication effort has been to provide sound, science-based information to counter the misinformation that is on the web about the safety and efficacy of ag biotechnology.

Many U.S. farmers who grow genetically engineered (GE) crops are realizing substantial economic and environmental benefits — such as lower production costs, fewer pest problems, reduced use of pesticides, and better yields — compared with conventional crops, says a new report, Impact of Genetically Engineered Crops on Farm Sustainability in the United States, from the National Research Council.  However, GE crops resistant to the herbicide glyphosate — a main component in Roundup and other commercial weed killers — could develop more weed problems as weeds evolve their own resistance to glyphosate.  GE crops could lose their effectiveness unless farmers also use other proven weed and insect management practices.

THERE ARE AT LEAST 1 BILLION POOR PEOPLE LIVING WITH CHRONIC UNDERNOURISHMENT, and the United Nations (UN) Millennium Development Goal of substantially reducing the world’s hungry by 2015 will not be met. The developing world’s poor are experiencing the effects of higher commodity prices, and declining agricultural productivity growth is exacerbating the problem. Next week, leaders in science and society will convene in Montpellier, France, for the first Global Conference on Agricultural Research for Development (GCARD 2010) to organize sweeping changes in global agricultural research. The meeting follows major reforms of the Consultative Group on International Agricultural Research (CGIAR), endorsed in December 2009. CGIAR’s new business model is meant to more effectively address food security, focusing on people, results, and efficiency. “Mega Programs” (now called “Themes”) will deliver research outputs to achieve scaled-up impacts on poverty, and a new fund will harmonize donor contributions to support CGIAR’s 15 research centers. But the total global investment in public-sector agricultural research is 20 times greater than that of CGIAR. How to better harness this critical resource (along with private-sector investments) for worldwide poverty reduction will be a major focus for GCARD. Read the rest of this entry »

“Instead of redesigning the factory farm to suit the animals, they are redesigning the animals to suit the factory farm”
Matthew Scully. The American Conservative, May 23, 2005.

My most memorably painful experience occurred when I was a teenage farm kid that stomped on the end of a pitchfork. My intent was for the handle to swing up and whack my sister in the hand. Alas, she was not the embarrassed teenager who left for our family vacation the next day with a well deserved set of stitches. In the seconds after the handle did its damage, I knew where I was hurting, I knew that it was a rather intense sensation, and I knew that it was not at all pleasant. What I did not know was that these experiences where the result of two different sensory pathways. The first pathway told me that my chin hurt, and badly; the second told me that it was not pleasant (for me at least – my sister was on the ground laughing). Read the rest of this entry »
