Figures from the Institution of Mechanical Engineers show as much as
2bn tonnes of food never makes it on to a plate

----

As much as half of all the food produced in the world – equivalent to
2bn tonnes – ends up as waste every year, engineers warned in a report
published on Thursday.

The UK's Institution of Mechanical Engineers (IMechE) blames the
"staggering" new figures in its analysis on unnecessarily strict sell-
by dates, buy-one-get-one free and Western consumer demand for
cosmetically perfect food, along with "poor engineering and
agricultural practices", inadequate infrastructure and poor storage
facilities.

In the face of United Nations predictions that there could be about an
extra 3 billion people to feed by the end of the century and growing
pressure on the resources needed to produce food, including land,
water and energy, the IMechE is calling for urgent action to tackle
this waste.

Their report, Global Food; Waste Not, Want Not, found that between 30%
and 50% or 1.2-2bn tonnes of food produced around the world never
makes it on to a plate.

In the UK as much as 30% of vegetable crops are not harvested due to
their failure to meet retailers' exacting standards on physical
appearance, it says, while up to half of the food that is bought in
Europe and the US is thrown away by consumers.

And about 550bn cubic metres of water is wasted globally in growing
crops that never reach the consumer. Carnivorous diets add extra
pressure as it takes 20-50 times the amount of water to produce 1
kilogramme of meat than 1kg of vegetables; the demand for water in
food production could reach 10–13 trillion cubic metres a year by
2050.

This is 2.5 to 3.5 times greater than the total human use of fresh
water today and could lead to more dangerous water shortages around
the world, the IMechE says, claiming that there is the potential to
provide 60-100% more food by eliminating losses and waste while at the
same time freeing up land, energy and water resources.

Tim Fox, head of energy and environment at the IMechE, said: "The
amount of food wasted and lost around the world is staggering. This is
food that could be used to feed the world's growing population – as
well as those in hunger today. It is also an unnecessary waste of the
land, water and energy resources that were used in the production,
processing and distribution of this food."

In order to prevent further waste, governments, development agencies
and organisation like the UN "must work together to help change
people's mindsets on waste and discourage wasteful practices by
farmers, food producers, supermarkets and consumers," the IMechE said.
