Recent worldwide food shortages and price hikes have yet again prompted proponents of Genetically Modified (->GM) crops to release statements and ads
calling for an expansion of their use, often using flashy catchphrases like
fighting world hunger.
From data i gathered for threads i wrote for this forum in the past, it becomes obvious that this promise, like many others, is an empty one.
Before i post url's to older threads let me state that the difference, with regard to overall yields and longetivity, sustainability and the
forgotten subject of
soil depletion is one of agricultural practices, not primarily
one of crop varieties. There's an article i pulled from a search engine, calling for a new
Green Revolution.
To American biologist Robert Zeigler, the request underscores two global problems: rapidly depleting grain stockpiles, and the need for a new Green
Revolution to satisfy food demand that is forecast to jump 50 percent by 2025
which reminds me strongly of something i've written 1 1/2 years ago:

Punjab and Haryana were at the forefront of the Green Revolution in the late 1960s and early 1970s, in which farm machinery, pesticides and
fertilisers, irrigation and the replacement of traditional crops with high-yielding varieties dramatically increased productivity. The two states
together now provide 80 per cent of the country's food surplus.
But the land is increasingly unable to support this burden of intensive agriculture. Crop yields--and water resources--are declining alarmingly,
and some parts are close to becoming barren. Many farmers are heavily in debt from their investments in new equipment and reliance on chemicals,
and rural unemployment is increasing. These are ominous signs of a deteriorating farm economy.
industrialised agriculture did in fact vastly increase yields, for a few decades, it is now seen to decline in areas, where the environment was more
fragile or susceptible to the perils of water depletion and soil erosion. Calling for another round of Green Revolution sounds scary, imho, because
diminishing returns are to be expected and this would mean only a few years of higher yields - IF the PR contained some truth, which, as far as i can
tell, it does not.
Now, on to the main issue.
GM crops, real life experiences:
Argentina
The growth in output is exclusively the result of an increase in the
area of land under soya bean cultivation. Despite the early promises, RR
soya beans have had five-six per cent lower yields than conventional
soya. Nor has there been the much-heralded decline in pesticide
application. Because of the evolution of vicious new weeds, farmers have
had to use two or three times more pesticides than previously. Overall,
total costs have risen by 14 per cent. Soya prices have dropped as a
result of increased global production, and most farmers are actually
worse off.
India
The Indian government confirmed that Bt cotton’s disastrous yields cost millions. One state even kicked out Monsanto, after they refused to
compensate farmers’ losses. Tragically, hundreds of debt-ridden cotton farmers committed suicide.
North America
Lower profits for farmers growing GM crops: The profitability of growing GM herbicide tolerant soya and insect-resistant Bt maize is less than
non-GM crops. This is due to the extra cost of GM seed (which can be up to 40% higher), the lower market prices paid for GM crops, and reduced soya
yields.
The list is endless, if i was foolish enough to overload the thread with links and quotes, which i won't. i won't go into the deletreious effects on
soil ecology or ecology as a whole, either or adverse health effects in animal trials or elsewhere, because these threads have, of course, already
been posted.
My intention is to raise awareness that food shortage is an excellent pretext for forcing yet another destructive practice on the world, the West's
reluctance to ban bioful processing from food crops (or rivalling crops, which are displacing food crops) clearly shows that they could not care less
about the danger famine, in fact the profits are probably good. Furthermore, with sky high royalties payments, a higher price might just be what the
doctor prescribed to give the industry a boost.
The solution might lie in using techniques which, while labor intensive, have proven sustainable and reliable, let me illustrate.

Last week, Nature magazine reported the results of one of the biggest agricultural experiments ever conducted (2). A team of Chinese scientists had
tested the key principle of modern rice-growing - planting a single, high-tech variety across hundreds of hectares - against a much older technique:
planting several breeds in one field. They found, to the astonishment of the farmers who had been drilled for years in the benefits of
"monoculture", that reverting to the old method resulted in spectacular increases in yield. Rice blast - a devastating fungus which normally
requires repeated applications of poison to control - decreased by 94 per cent. The farmers planting a mixture of strains were able to stop applying
their poisons altogether, while producing 18 per cent more rice per acre than they were growing before.
let me write that out: Eighteen Percent, nearly a Fifth.
There's no profit in it for the corp's, but such practices will feed the poor and might even give them an income if they manage to produce in excess
(<- which in turn effectively reduces the clout of the corp's). This development ties neatly into all biofuel initiatives, only that this is stage 2,
with potential long-term effects. Both will eventually serve to diminish the resource food in order to attain higher margins, if left unchecked. I
hope i don't need to stress tha fact that once people begin to starve, especially if needlessly and through the arrogance of a few disconnected
people, our days of peace and positive outlook will be numbered!
