Nearly two billion people depend on imported food

- Researchers show empirically: when population pressure increases, food is imported. The big issue, say authors of a new report, is that people may not even be aware that they have chosen dependency on imports over further investment in local production or curbing demand.
Earth’s capacity to feed its growing population is limited — and unevenly distributed. An increase in cultivated land and the use of more efficient production technology are partly buffering the problem, but in many areas it is instead solved by increasing food imports. For the first time, researchers at Aalto University have been able to show a broad connection between resource scarcity, population pressure, and food imports, in a study published in Earth’s Future.
‘Although this has been a topic of global discussion for a long time, previous research has not been able to demonstrate a clear connection between resource scarcity and food imports. We performed a global analysis focusing on regions where water availability restricts production, and examined them from 1961 until 2009, evaluating the extent to which the growing population pressure was met by increasing food imports,’ explains Postdoctoral Researcher Miina Porkka.
