What's more, the pace of productivity growth has declined to an
average of 1.3% over the past 20 years, despite the introduction of
genetically modified seeds. Stockpiles are meagre, with US corn
inventories at a 35-year low and the EU's grain mountains depleted.
Given all this, agricultural prices are set to rise further."

Oh Good!

Interesting that GM is not making a big difference in output, however, one
would really need to look at the productivity growth on a 4-5 yr basis
after GM took off in the Americas and far east

AFAIK, the advantage of GM is savings on sprays.. disease resistance.

Vastly outweighed by the disadvantages to society.

one is:

Study shows disadvantages of GM foods to human health

British scientific researchers demonstrated that genetically modified
DNA from crops can find its way into human gut bacteria, raising
possible health concerns. This is because antibiotic-resistant marker
genes are inserted with GM material, which could cause a person to be
resistant to antibiotic medicines.

The study was conducted at Newcastle University on seven human
volunteers who, in the past, had their lower intestine removed and now
use colostomy bags. After eating a burger containing GM soy,
researchers compared their stools with 12 people with normal stomachs.
They found "to their surprise" that "a relatively large proportion of
genetically modified DNA survived the passage through the small
bowel." None was found in people who had complete stomachs. To see if
GM DNA might be be transferred via bacteria to the intestine, they
also took bacteria from stools in the colostomy bags and cultivated
them. In three of the seven samples they found bacteria had taken up
the herbicide-resistant gene from the GM food at a very low level.

Michael Antonio, a senior lecturer in molecular genetics at King`s
College Medical School, London, said that the work was significant
because the researchers demonstrated that you can get GM plant DNA in
the gut bacteria, which was previously considered to be not possible.
Antonio said the research suggests that antibiotic marker genes could
spread around the stomach and compromise antibiotic resistance. If
this were to happen, a person could be immune to beneficial
antiobiotic medicines.

Marker genes are inserted into GM plants to allow identification of GM
cells or tissue during development. The House of Lords has called for
them to be phased out as swiftly as possible. The research was
conducted at the request of the UK's Food Standards Agency, which
released a statement saying the research, "concluded that the
likelihood of functioning DNA being taken up by bacteria in the human
or animal gut is extremely low."
