This post is the second installment of WRI’s blog series, “Creating a Sustainable Food Future.” The series explores strategies to sustainably feed 9 billion people by 2050. All pieces are based on research being conducted for the 2013-2014 World Resources Report. Look for the next installment tomorrow, which will highlight a number of solutions to reduce food loss and waste.
The world produces about 4 billion tons of food per year, or about 6 quadrillion calories. That’s a large amount, but what’s really shocking is that nearly one-quarter of these calories go uneaten.
This food is lost or wasted in a number of ways. It might rot in the fields, get eaten by pests in storage, or be thrown away by a grocer or consumer, just to name a few. It’s a problem that must be mitigated: The world will need about 60 percent more calories per year by 2050 in order to adequately feed the projected population of more than 9 billion people. WRI’s new working paper, Reducing Food Loss and Waste, shows that cutting current rates of food loss and waste in half would reduce the size of this food gap by about 22 percent.
The new paper, part of the ongoing 2013-2014 World Resources Report: Creating a Sustainable Food Future working paper series, looks at the scale of the food loss and waste challenge and examines how we as a global community can start tackling this issue. The paper and tomorrow’s blog post explore a number of practical, affordable strategies for governments, businesses, and households to reduce their loss and waste immediately.
But first, it’s important to understand the extent of the problem. Here are several facts and figures that reveal just how much food the world loses and wastes:
