This week Science published research ($ub. req'd) detailing the vast, global food-security implications of warming temperatures. The colored graphics are nothing short of terrifying when you realize the blotches of red and orange covering the better part of the globe indicate significantly warmer summers in coming decades.
The implications of the article are clear -- we need to be utilizing agricultural methods and crops that can withstand the potential myriad impacts of global climate change, especially warmer temperatures. The article significantly notes, "The probability exceeds 90 percent that by the end of the century, the summer average temperature will exceed the hottest summer on record throughout the tropics and subtropics. Because these regions are home to about half of the world's population, the human consequences of global climate change could be enormous."
Whether you believe global warming is part of a "natural cycle" or a man-made phenomenon is irrelevant. The bottom line is that our earth is rapidly warming, and this is going to drastically affect our food supply. We must undertake both the enormous task of reducing our carbon emissions now to avert the worst, while at the same time adapting our society to the vast and multitudinous effects of unavoidable global climate change. Failing to do either will, as the Science article indicates, have dire effects on a large portion of our world's population.
Determining the best course of action for ensuring food security in the face of global climate change remains a challenging task. Recognizing that climate change is slated to affect developing countries and small-scale farmers the most is a crucial point. Such understanding enables people to realize that viable solutions must be accessible, affordable, and relevant to the billions of small-scale farmers in the developing world. Unfortunately, it appears that some of the solutions on the table fail to meet these criteria.
Last week, Monsanto made a big public relations splash by filing documents with the FDA regarding a drought-tolerant GM corn variety it is developing with a German company, BASF. Monsanto claims that in field trials, the corn got 6-10 percent higher yields in drought-prone areas last year, but the release is extremely short on details. Regardless of the reality, Monsanto is presenting the corn as a way to help improve on-farm productivity in other parts of the world, notably Africa.
Yet, absent from the media hype were the many technical and social problems with Monsanto's corn.
