With UN predictions that there
could be about an extra three billion people to feed by the end of the century
and an increasing pressure on the resources needed to produce food, including
land, water and energy, the Institution is calling for urgent action to tackle
this waste.
In the UK as much as 30% of
vegetable crops are not harvested due to them failing to meet exacting
standards based on their physical appearance, while up to half of the food
that’s bought in Europe and the USA is thrown away by the consumer. Also, about 550 billion m3 of water is wasted
globally in growing crops that never reach the consumer. It takes 20-50 times the amount of water to
produce 1 kilogram of meat than 1 kilogram of vegetables.
In the end, engineers have a
crucial role to play in preventing food loss and waste by developing more
efficient ways of growing, transporting and storing foods. But overall it is a team effort where
Governments, development agencies and organizations 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.
