Food for All
14/11/2013-Mareeg.com-LONDON – With food prices having doubled in the past decade, food security is back
on the international agenda. How can the world produce more to feed the next billion
people? How can agricultural yields be raised? What is the best way to develop
Unfortunately, this focus on the supply side misses half the problem. The world
already produces more than twice the number of calories that the human population
requires. An estimated one-third of global food production is wasted. In poor
countries, food is lost due to inadequate storage and gaps in the supply chain (for
example, a lack of refrigeration); in rich countries, food is also wasted in the
supply chain, and consumers throw a lot of food away.
Moreover, in many cases, it is poverty, not lack of food in the market, that drives
hunger and nutritional deficiency. Millions of people simply cannot afford to buy
the food that they need, which could still be the case if supply were increased.
Fixing the demand side to get nutritious food to the poor – particularly to the
mothers and children who are most vulnerable – is one of the most pressing
A broad range of initiatives can contribute to a solution. For example, micro-level
food security can be enhanced through programs that deliver free meals to vulnerable
population groups. Schemes that provide free meals to schoolchildren not only help
to feed the young; they also create an incentive for parents to keep their children
in the classroom.
Initiatives like these are especially successful when complemented with programs
that provide access to clean water, energy, safe cooking stoves, and so on. Action
to reduce diarrhea – so that children retain the nutritional value of what they eat
– is another part of the solution.
Of course, in very poor countries and regions, where people cannot afford to buy
food on world markets, the supply side should not be neglected. Boosting yields of
locally grown staple foods (rather than cash crops) would increase self-sufficiency
and strengthen resilience when international food prices are high.
At the same time, higher agricultural production must be balanced against the
associated ecological and social costs. Output in South America, Southeast Asia, and
Central Africa currently is being raised mainly by clearing tropical forests,
grasslands, and wetlands. This approach contributes to climate change, interrupts
hydrological cycles, and causes soil degradation, all of which undermine our
planet’s ability to produce food in the long term.
If current trends continue, the majority of the world’s remaining species will be
extinct by the end of the century, and it is food production, above all other
factors, that has driven the decline. More than 80% of all endangered birds and
mammals are threatened by unsustainable land use resulting from agricultural
The lesson is clear: We should focus our attention on making production more
efficient, reducing waste, and addressing the problem of unsustainable consumption.
Reducing food waste could save more than $250 billion worldwide – the equivalent of
65 million hectares of agricultural land use – by 2030. Building a
temperature-controlled supply chain with 30,000 tons of modern storage in China
would cost more than $100 million a year for the next 20 years. Many developing
countries simply do not have the money for such up-front investment. But, with the
right focus and much more modest resources, they could dramatically improve the
quality of grain silos where more than 30% of food – typically located close to the
rural poor – spoils to the point of being unfit for human consumption.
There are already some positive trends that should be capitalized on globally. In
the past few years, households in the United Kingdom have cut their food waste by
21% and the food industry has trimmed its waste streams by 8%. The public is more
willing to forgo cosmetic perfection: “ugly” fruit and vegetables are the
fastest-growing sector of the UK’s fresh-produce market, last year saving 300,000
tons of produce that would otherwise have been wasted for being the wrong shape or
Much anxiety is directed toward growing demand for meat and dairy products in China
and India. But per capita meat consumption in the United States and Europe is still
more than three times higher than in either country.
In addition to eating less meat, production of it needs to be more
resource-efficient. In the past, cattle, sheep, and goats fed on grass and other
energy sources unavailable to humans, while pigs and chickens fed on waste, thus
contributing overall to total food availability. Now one-third of all arable land is
used to grow crops to feed livestock, not to grow staple crops for people. The rich
buy this food to feed their animals, outbidding the poor who want to buy it to feed
The United Nations Environment Program estimates that using more by-products and
waste to feed livestock could liberate enough food on the world market to feed an
additional three billion people. The Pig Idea campaign calls for an end to
legislation in the European Union and some US states prohibiting the use of food
waste to feed pigs and chickens because of the risk of animal diseases. These risks
can be managed effectively through proper treatment systems (as in Japan and South
Korea). The environmental, economic, and social benefits would be enormous.
The earth is capable of feeding everyone. Failing to address problems affecting
supply and demand amounts to grotesque mismanagement and a crime against the world’s
poor, the planet’s other species, and future generations.
