UNEP: Curb food wastage via traditional preservation methods

UNEP showcases traditional ways of preserving food, ahead of this year’s world environmental day in June. This goes a long way in preventing waste of food, which is one of the world’s most precious resources.

It is estimated that every year, about 1.3 billion tonnes of food produced ends up rotting in bins of consumers and retailers or spoil due to poor transportation and harvesting practices. Varying implications of the waste of food range from hunger to waste of energy put into growing the wood and fuel spent on transporting produce across various distances. In addition to this, significant amounts of methane gas emanate from food decomposition on landfills while while livestock and forests cleared for food production contribute to global warming. 

World Environment Day 2013, whose global host is the government and people of Mongolia, is focused on the new UN Environment Programme and UN Food and Agricultural Organization (FAO) campaign Think.Eat.Save. Reduce Your Foodprint, which is aimed at slashing this wastage.
Mongolia, one of the fastest-growing countries in the world is aiming to ensure this growth goes hand in hand with a green economy and civilization. It neither wastes nor loses food at any significant level, but the nomadic life of many of its people does offer some ancient answers to the modern-day challenge of food waste.

The UN Environment Programme (UNEP) has asked people to submit examples of traditional ways in which food is preserved. The methods demonstrate how humanity once valued food far more than it does today. 

They also highlight the irony that, in an era where technology makes it ever easier to store food for longer, most people make less effort to conserve food and thus waste money-all the more surprising considering the financial crisis that has forced many to tighten their belts and recent reports that world food prices are at a 40-year high.

The ways that indigenous peoples create preserved dishes are as many and varied as the cultures and food sources that form the basis of the recipes.

Mongolian general Chinggis Khan and his troops utilized a traditional food called borts to gallop across Asia without depending on elaborate supply chains. Borts is basically concentrated beef equal to the protein of an entire cow condensed and ground down to the size of a human fist. This remarkable method of food preservation, without refrigeration, produced a meal equivalent to several steaks when the protein was shaved into hot water to make soup.

Not too far away, the Turkish horsemen of Central Asia had their own solution. They would preserve meat by placing it in pockets on their saddles to be compressed by their legs as they rode. 

Further in the frozen north, the Inuit from Greenland dine on a dish called Kiviak-a traditional wintertime food made from Auks, a small bird that bears a superficial resemblance to a penguin. Hundreds of whole birds are wrapped in a seal skin, which then has the air removed before being sewn up. The skin is placed in the permafrost under a stone to help keep the air out. The birds then ferment for around seven months before they are dug up and eaten, often at celebrations..

In many countries of South America, a freeze-dried potato delicacy known as chuño, which pre-dates the Inca Empire, is widely eaten. The potatoes are alternately exposed to the freezing night air and hot daytime sun for five days, being trampled to squeeze out all moisture. Chuño can last for months or years.

In Nigeria and several other western African countries, a dry granular foodstuff called garri is produced from cassava tubers that are peeled, washed and grated. The resultant mash is placed in a porous bag and allowed to ferment as weights press out the water. Finally it is sieved and roasted for long-term storage.

There are so many more dishes to choose from: ghee, a type of butter that needs no refrigeration, milk powders and curds, biltong and other dried meats, pickles, jams, sauerkraut and dozens more.
These methods show just how much room there is for individual consumers to take the lead from their forebears and change the way they buy, store and consume food.
