Organic Update December 2007

2007 a Good Year
2007 has been a very good year for the organic sector in Australia and around the world. The growth of sales in organic products is very robust. A large number of studies on the positive health benefits of organic food were published. This edition contains even more studies, especially on the antioxidant benefits. 2007 saw more research on the environmental benefits of organic farming in terms of soil health, water use efficiency and climate change. Further studies revealed more problems with synthetic pesticides and GMOs and highlighted the importance of a farming system that avoids these toxic and artificial inputs. GMOs
The Organic industry will now have to work hard to have governments mandate realistic segregation policies to ensure that organic products are not accidentally contaminated with GMO products or DNA. The costs of this should be paid for by the GMO industry and not by the organic sector. Governments will need to introduce legislation that allows fair compensation for financial losses that occur due to contamination. The financial burden and responsibility of contamination must be put on the GMO industry. Biofach All the best for the festive season and 2008 Best Regards

Organic Foods have Higher Levels of Bioavailable Antioxidants
Dr. Neal Davies leads the research team at WSU. Using sensitive techniques, they measured the levels of three flavonoids and their enantiomers in conventional and organic fruit and tomato juices, and for the first time ever, quantified both the glycoside (molecule with attached sugars) and agylcone (molecule stripped of sugars) forms of the enantiomers of these three flavonoids. Organic lemonade had ten-times the total eriocitrin (glycoside form of eriodictyol) compared to conventional lemonade, and the agylcone form had over three-times the level in conventional juice. Organic lime juice also had three-times the level of eriocitrin, compared to conventional lime juice. Organic apple juice had over three times the total hesperidin (glycoside), and almost twice the hesperetin (agylcone form). Organic grapefruit juice had about 20% less total hesperidin (glycoside), but 77% more hesperetin (agylcone). The importance of measuring both the glycoside and agylcone form of flavonoids (and other nutrients) is clear in the grapefruit juice findings. Based on the data for just the glycoside form of hesperidin, it would appear that conventional grapefruit juice contains more of this flavonoid than the organic juice that was tested. But by focusing on the more bioavailable agylcone form, the opposite conclusion would be reached. Source: J.A.

Organic production increases antioxidant levels by, on average, about 30%, as shown in the Organic Center's State of Science Review on antioxidants. ROS damage to cells, chronic inflammation, and heart disease are among the common and costly complications of diabetes. A team of scientists in Korea have found that proanthocyanidins, antioxidants in several fruits and vegetables, substantially reduce the damage caused by ROS and inflammation in diabetic rats.

The Release of GM Canola and the Proposal to End GMO Moratoriums
The decision by the NSW and Victorian government to end the moratoria on GMOs is disappointing especially in the light of the mounting evidence about the negative health and environmental effects of artificial plants. The Organic industry will now have to work hard to have governments mandate realistic segregation policies to ensure that organic products are not accidentally contaminated with GMO products or DNA. The costs of this should be paid for by the GMO industry and not by the organic sector. Governments will need to introduce legislation that allows fair compensation for financial losses that occur due to contamination. The financial burden and responsibility of contamination must be put on the GMO industry. French President Proposes Moratorium on GMOs and cuts in Pesticide Use

Synthetic Nitrogen Fertilisers Deplete Carbon
The researcher found that the higher the application of synthetic nitrogen fertiliser the greater the amount of soil carbon lost as CO2. This is one of the major reasons why conventional agricultural systems have a decline in soil carbon while organic systems increase soil carbon.
Organic Farmers Help Stop Climate Change
According to Dr Christine Jones, one of Australia’s leading experts on carbon sequestration a 1% increase in organic carbon in the top 20 cm of soil represents a 24,000 kg per hectare increase in soil carbon which equates to 88,000 kgs of CO2 sequestered. In a 100 hectare farm this would be around 8,800,000 kgs of CO2 sequestered from the atmosphere. Organic farmers are helping to ameliorate climate change by sequestering huge quantities of CO2 Continuous Monocultures Yield Lower than Crop Rotations
New research from the University of Illinois have found that yields were 20% lower for continuous corn cropping when compared to corn, oats and hay rotations. Source: Acres USA Organic Farming Superior to No-till Conventional Production in Building Soil Quality
A USDA plant physiologist, Dr. John Teasdale, has published an important paper in the Journal of Soil and Water Conservation entitled "Strategies for Soil Conservation in No-tillage and Organic Farming Systems" (Nov/Dec 2007, Vol. 62, Number 6). He concludes that: "Results of this research suggest that organic farming systems can provide greater long-term soil improvement than conventional no-tillage systems, despite the use of tillage in organic systems."
BioFach, the World Organic Trade Fair, 21-24 February 2008
2,600 exhibitors will present their products to the some 45,000 visitors at BioFach 2008, the World Organic Trade Fair and the organic world’s most important get-together. BioFach, which takes place in Nuremberg from 21-24 February, has another highlight lined up for 2008 – the new Wine Hall 4A. This puts organic wine in the limelight and the culinary event worlds in the Wine Hall have some real organic delights in store for visitors. Vivaness, the Trade Fair for Natural Personal Care and Wellness in hall 7A and part of hall 7, celebrates its first birthday in 2008. Wal-Mart Updates Sustainable Strategy
The use of more sustainable raw materials in textiles and clothing is part of a much wider strategy by the world’s biggest retailer to reduce its overall impact on the environment, and was outlined today in a new report that also defines the challenges, as well as Wal-Mart’s goals, for moving forward. Wal-Mart is currently the largest single buyer of organic cotton in the world and also the world’s largest purchaser of conversion cotton. In 2007, the company partnered with a large cotton spinner to commit to the purchase of more than 10 million pounds of conversion cotton. Source: Biofach and www.ecotextile.com
USA Organic Industry Grew by 21 % in 2006
Meanwhile, U.S. sales of non-food organic products grew from $744 million in 2005 to $938 million in 2006, reflecting a 26 % growth rate. Non-food categories include organic supplements, personal care products, household products and cleaners, pet food, flowers, and fiber products such as linens and clothing. Demand for meat, currently the smallest category, increased by 55 % last year. Dairy, the largest segment, had an increase in sales of 25 %. Fruit and vegetables showed the smallest growth rate between 2005 and 2006 (11 %). Source: Biofach and www.ota.com
