Report IV

The report contrasts ecological farming with chemical and GM agriculture, asserting that the latter degrades soil and harms the food chain. It cites historical and modern evidence that biodiverse, organic methods increase crop yields and improve the health of plants, animals, and humans, while GM crops are linked to lower yields, increased herbicide use, and potential soil fertility damage.

• Ecological farming methods, based on biodiversity and organic manuring, can match or exceed the yields of intensive agrochemical agriculture, with some cases showing yields being doubled or trebled. In contrast, monocultural planting used for GM crops reduces total yield per area.
• Evidence suggests that Roundup Ready (RR) soya beans yield 5-10 percent less than conventional varieties and require significantly more herbicides, with some farmers using 2 to 5 times more herbicide per acre in 1998.
• Chemical and GM agriculture negatively impact soil health and organisms. US researchers estimated that non-organic managed farms could lose all topsoil within 50-100 years. Furthermore, GM Bt crops may harm earthworms and exude toxins at levels 10-20 times higher than conventional pesticides, potentially leaching into the soil and affecting insect larvae.
• The report claims that organic farming leads to superior health outcomes across the food chain. It notes that animals fed organically show better growth and reproduction, and that no cases of BSE were found among animals born and bred on organic farms during the outbreak.
• There are concerns regarding the long-term effects of GM crops, including the potential for GM genes to leak into soil micro-organisms and transfer horizontally, which could cause irreparable damage to soil fertility.
