2b people rely on imported food
Almost 2.0 billion people in world now rely on imported food, new research shows.
According to the latest findings, 1.4 billion people rely on food produced elsewhere. Another 460 million live in regions where imports fail to make up for the shortcomings of the local food supply.
The study, conducted by scientists at Aalto University in the Netherlands, is one of the first to analyze the connections between resource scarcity, population growth and food imports. It was published this week in the journal Earth's Future.
As populations grow, pressures on regional water and soil resources increase. When local agriculture can't keep up, populations must look elsewhere.
"It seems obvious to look elsewhere when local production is not sufficient, and our analysis clearly shows that is what happens," said study co-author Joseph Guillaume. "Perhaps that is the right choice, but it should not be taken for granted."
