It’s easy to link rising human populations with food insecurity. Too bad that explanation is often oversimplistic.
It’s nice to see this article in the NY Times (Food Experts Worry as World Population and Hunger Grow), which basically gets right many of the underlying features of food insecurity.
Let’s consider several of the points:
Scientists and development experts across the globe are racing to increase food production by 50 percent over the next two decades to feed the world’s growing population, yet many doubt their chances despite a broad consensus that enough land, water and expertise exist.
….The global financial recession added at least 100 million people by depriving them of the means to buy enough food, but the numbers were inching up even before the crisis, the United Nations noted in a report last week.
If there is one main point from the Nobel-prize winning work of Amartya Sen, who studied the Bengali and Ethiopian famines, it’s that poverty is one of the main determinants of food insecurity, not lack of food production. People are often too poor to buy food, even when it’s produced in overabundance, and poor food distribution systems often compound that effect, as the next quotes illustrate:
“The way we manage the global agriculture and food security system doesn’t work,” said Kostas G. Stamoulis, a senior economist at the organization. “There is this paradox of increasing global food production, even in developing countries, yet there is hunger.”
….But the conundrum is whether the food can be grown in the developing world where the hungry can actually get it, at prices they can afford. Poverty and difficult growing conditions plague the places that need new production most, namely sub-Saharan Africa and South Asia.
The next quote reiterates some of the points I made in an earlier post that chronic humanitarian aid often exacerbates food insecurity by undercutting the development of a profitable agricultural system in poor countries:
Mrs. Clinton often calls agriculture aid a critical issue, saying the administration supports domestic efforts in developing nations and improvements in production by small farmers, particularly women. Philip J. Crowley, a department spokesman, said, “We are trying to shift away from emergency aid toward agricultural development.”
One part of this article that’s worth criticizing is this quote about genetically modified (GM) crops:
Then there is the question of genetically modified crops. No issue provokes such an emotional division among agronomists, who debate whether they constitute the building blocks of a second green revolution or a health menace.
“Who is steering this fear and global paranoia about the G.M. cotton and all these G.M. crops?” said Hans P. Binswanger-Mkhize, a South African agriculture consultant. “Show us where the corpses are — the corpses of earthworms, the corpses of bees, the corpses of antelopes and the corpses of humans. Nobody has yet ever shown us a corpse.”
Forget the health issues and dead bugs (for now)…how about the 100,000 indebted Indian farmers who have committed suicide over the past several years? Not because of GM crops per se but because of the economic outcomes of technology packages, of which GM crops are a part:
Sure, technology will likely play a needed role in boosting world food production. But technology advocates need to temper their enthusiasm with an understanding of the social side effects that magnificent yield gains bring about in poor, developing nations. Read the Newman article before jumping on the technology-solves-everything bandwagon.

A few years ago, authors Steven Leavitt and Stephen Dubner wrote the bestseller, Freakonomics: A Rogue Economist Explores the Hidden Side of Everything.
Their follow up—out yesterday– is called SuperFreakonomics: Global Cooling, Patriotic Prostitutes, and Why Suicide Bombers Should Buy Life Insurance. As the provocative title suggests, they are wading into climate change.
Early response to chapter 5 on climate change has been hostile. The book is being widely panned for scientific and economic inaccuracies, repetition of discredited ideas about global cooling, as well as false portrayals of the lead scientists interviewed.
Here’s the low down:
In their defense, Levitt and Dubner argue they are not contesting climate warming, only considering possibilities for how to cool it with geoengineering.
Here’s their response (part 1, part 2).

Harvard University President, Drew Gilpin Faust, argues in the NY Times that higher education, in order to deal with global challenges like climate warming, needs to return to its liberal arts principles rather than producing countless numbers of business majors.
Some excerpts:
The world economic crisis and the election of Barack Obama will change the future of higher education. Even as universities, both public and private, face unanticipated financial constraints, the president has called on them to assist in solving problems from health care delivery to climate change to economic recovery….
As the world indulged in a bubble of false prosperity and excessive materialism, should universities — in their research, teaching and writing — have made greater efforts to expose the patterns of risk and denial? Should universities have presented a firmer counterweight to economic irresponsibility? Have universities become too captive to the immediate and worldly purposes they serve? Has the market model become the fundamental and defining identity of higher education?
As a nation, we need to ask more than this from our universities. Higher learning can offer individuals and societies a depth and breadth of vision absent from the inevitably myopic present. Human beings need meaning, understanding and perspective as well as jobs. The question should not be whether we can afford to believe in such purposes in these times, but whether we can afford not to.
Others have argued similarly in the Times recently (Is it Time to Retrain B-Schools? and End the University as We Know It.)
Are these isolated rumblings, or is there a more fundamental problem, first identified by Wendell Berry and David Orr years ago, that the way we train students and structure higher education contributes to the major environmental and social problems we now face?
What does it mean to train students to be successful in a world that is ecologically unsustainable and socially unjust?

This column in the Guardian (Climate action shouldn’t target poor farmers) as well as work by Peter Singer illustrate some of the tradeoffs associated with the trend towards eating more organic and locally sourced food.
Is it better to eat locally or import food from poorer, developing nations?
One of the big problems uncovered recently is the fact that humanitarian food aid may be undercutting the ability for poor farmers to establish profitable, self-sustaining agricultural systems, thereby perpetuating food insecurity. There is nothing worse than competing with free food if you are a fledgling producer.
If developed nations reduce agricultural imports from developing countries because of the locavore movement, this, too, could undermine long-term agricultural development and increase the risk of food insecurity.
It’s important to note that this argument is a bit simplistic. International trade is complex, affecting food security in several ways:
Another issue is organic foods. As Singer asks, is it better to buy organic food locally or from a developing nation like Mexico? The food miles associated with international transport increase carbon emissions, but the tradeoff is supporting organic farming economies in developing countries.

In the latest issue of Conservation Biology, Nelson and Vucetich1,2 tackle the thorny issue of whether scientists can/should also be environmental advocates. This is one of the better, more philosophical, analyses I have seen.
For scientists worried that advocacy undercuts credibility, this piece may allay your concerns. I recommend reading the whole article (it’s a rich analysis).
Here’s the conclusion as a short excerpt:

Risk analysis is a four-step process by which scientists determine whether chemicals or other agents are unhealthy:
As the EPA will tell you, there is often poor understanding of the long term risks of synthetic chemicals and radiation. Much of this comes from the fact that
For the majority of the approximately 3,000 high production volume industrial chemicals produced in the United States in 1996, we have little or no publicly available hazard screening data. These chemicals, non-polymers produced in quantities of more than one million pounds per year, are found in the workplace and in thousands of consumer products. Even fewer data are available for the remainder of the some 70,000 chemicals on the EPA’s inventory.
Thus, we know we are exposed to these things, and we can even measure them in our bodies and in infants, but we don’t know very well how this translates to long term health risk.
To some, this uncertainty might be license to ignore the issue. To others, it necessitates better education about what’s in or emanating from our products so that we can decide for ourselves whether or not to limit exposure.
The Environmental Working Group has compiled several interesting lists of consumer products including specific ingredients that have the potential to be harmful:
So go ahead and check out your favorite vegetable, shampoo, cell phone, or toothpaste, and see what comes up.
