In
Africa, a perfect storm for food security

Food
prices are rapidly heading toward new record territory, with far more
at play than a simple drought in the US Midwest. There are serious
implications, especially for nations with high rates of inequality
and poverty. We will almost certainly face a potentially
catastrophic, global scale famine in the next couple of decades.
The
main reason there are now over seven billion people on earth is
largely due to the emergence of two separate technologies. Firstly,
cheap fossil fuels have enabled us to grow food on industrial scales.
We presently require around 10 calories of fossil fuel energy to
produce one calorie of food. A century ago each calorie of energy
expended produced two calories of food. Secondly, advances in health
care, primarily antibiotics and vaccines, have increased human
life-spans.
It
is an increasing challenge to feed this exponentially increasing
population. We produce sufficiently for everyone on earth to have
enough food, yet despite this cornucopia a significant proportion of
people cannot afford to eat properly. Why?
There
are three major reasons for this. Firstly, unequal wealth
distribution. Secondly, meat consumption has grown as wealth has
increased. Grazing area for meat production, mainly beef, uses more
than a quarter of ice-free land surface. Additionally, more than a
third of all cropland is used to grow crops to feed livestock. These
are produced using energy intensive, industrial agricultural
practices.
Third,
the risks associated with diminishing energy supplies has encouraged
wealthy governments to promote the production and consumption of
"biofuels". These are produced from agricultural resources
such as sugar cane, beet, maize, soy, and oil crops such as palm oil
and canola.
This
focus on biofuels - which opponents prefer to call agro-fuels because
of their propensity to divert scarce agricultural resources toward
fuel crops - has caused an unprecedented shift in focus in
agricultural production from food production to growing fuel crops.
As
a result swathes of sensitive ecosystems have been destroyed to be
planted by monocultures like palm oil, sugar cane, maize and soy.
High oil prices have provided a potent economic incentive to underpin
this ecologically disastrous shift. This destruction is occurring
from the jungles of Indonesia - displacing iconic species like
ourang-outang - to West Africa, where local communities are expelled
in order to attract "foreign investment" and plant agrofuel
crops.
Biofuel
production has a clear impact on global food reserves, which are
presently approaching historical lows. Last year nearly 40% of the US
maize crop went into ethanol for fuel. Because the US is the world's
largest maize producer this has serious implications for global food
trade. This is especially so in light of this year's serious drought
across the Midwest. Maize prices have risen to record levels, nearly
double that of last year.
High
oil prices will maintain demand for maize ethanol, perpetuating the
insanity of food for fuel. The global trade in these commodity crops
is dominated by three corporations - Cargill, Bunge and Archer Daniel
Midland - each deeply involved in both ethanol production and market
hedging and speculation.
This
commodification of food leaves food security at the mercy of the
market. There is no central global oversight or planning to secure
sufficient food stocks as a buffer. Food is controlled by the market,
not by logic, and certainly not by benevolence. […]
In
turn, climate change is increasingly related to instability in
agricultural productivity. Sharply increased levels of carbon dioxide
and more recently, methane released as the Arctic fringe rapidly
thaws, has exacerbated this uncertainty. This feedback spiral places
agricultural production at further, direct risks.
Climate
change is more about increasingly unpredictable and extreme weather
events than pure "warming." The harbingers of these changes
are events like droughts in the US Midwest, Russia, South Asia,
melting of the Arctic ice cap and permafrost and floods in Pakistan,
Burma, and North Korea. […]
