Up to 50 Percent of Food
Is Wasted Worldwide, Report Says
As much as half of the food produced globally is wasted
each year as a result of inefficient agricultural practices, inadequate storage facilities and transportation systems, and wasteful consumer habits, a new report says. While the world community produces about 4 billion metric tons of food annually, roughly 1.2 to 2 billion metric tons of that food — or 30 to 50 percent — is never consumed, according to the UK-based Institution of Mechanical Engineers
. The causes of waste vary from region to region, the report says. In developing nations, much of the waste occurs at the local level as a result of inefficient harvesting, lack of transportation, and poor infrastructure and storage. In richer nations, the waste is often triggered by customer and retail behavior. For example, as much as 30 percent of UK vegetables are never harvested because their appearance doesn’t meet consumer standards. “This level of wastage is a tragedy that cannot continue if we are to succeed in the challenge of sustainably meeting our future food demands,” the report says. The report’s calculations do not include the amount of water and energy used in the production of wasted food.
