You may have heard of the new genetically engineered Simplot potato. It was made with a new GE technology called RNAi (RNA interference), a technology for which many important gaps remain in our understanding.
In fact, when the U.S. Environmental Protection Agency (EPA) recently asked a panel of independent scientists for advice about this technology, which alters the function of genes in the plant, the scientists wrote a detailed report [PDF] that warned the agency of risks that could sometimes result in harm.* And, they noted that current regulations were not well designed to address these risks.
But those concerns didn’t keep the U.S. Department of Agriculture (USDA)—the agency with the greatest responsibility to prevent environmental impacts of GE plants—from approving the Simplot potato. Read more
Industrial agriculture has huge, unsustainable impacts on our environment. And while organic and other ecologically based farming systems (agroecology) have huge benefits, some have suggested that it will never produce enough food. Production is only one of the challenges for food security. But, according to new research, even by this measure, critics seem to have substantially underestimated the productivity of organic farming. Read more
Genetically engineered (GE) seeds are often sold to farmers and the public on the grounds that they are the wave of the future, taking over where conventional plant breeding left off by improving productivity and sustainability. But that might be changing. Read more
As you may have heard, about half a million people in the Toledo, Ohio area lost their municipal drinking water supply on Saturday because of possible microbial toxin contamination from Lake Erie. A combination of heavier spring rains, exacerbated by climate change, and runoff of phosphorus from fertilizer applied to crops is the likely cause. The good news is that farmers can adopt better practices to eliminate this problem. The bad news is that the agriculture industry, and the public policies that it lobbies for, work against these solutions. Read more
Genetically engineered (or GMO) corn that was developed to kill insect pests has been causing resistance in some of those very insects for several years. But the issue has not received as much attention as it should. A new research paper in the prestigious journal, Proceedings of the National Academy of Sciences (PNAS), may change this by providing additional cause for concern. Read more
As reported in the New York Times, the prestigious World Food Prize was awarded this week to a trio of scientists who had important roles in the early development of crop genetic engineering. One, Robert Fraley, is at Monsanto, and another Mary-Dell Chilton, is with another seed giant, Syngenta. The third is European scientist Marc Van Montagu. Read more
A new article in the respected journal BioScience raises important concerns about the harmful influence of genetically engineered herbicide resistant crops on sustainable weed control. As many others have also noted, the excessive reliance on glyphosate-based herbicides, such as Roundup, has resulted in the emergence and spread of many harmful weeds that can no longer be controlled by glyphosate. These weeds now infest millions of acres of farmland the U.S., resulting in greater herbicide use.
But the new article goes well beyond most previous work by providing insight into the state of weed control for major crops in the U.S., and how the current use of engineered herbicide resistant crops is driving agriculture toward reduced sustainability. Read more
