The new UN climate report shows that crop yields already are being adversely affected by a changing climate, and how we respond globally in creating a more resilient food system is very important now. But we also recognize that food is central to our culture and is a source of great pleasure and comfort to people. We want to ensure we tackle all aspects so that we have enough food for the future.
The estimate of more than 9 billion people in less than 40 years highlights a stark challenge for the global food system.
We have enough food for the roughly 7 billion people alive today, but nearly a billion are hungry or malnourished, mostly due to poverty and unequal distribution. To feed those who are currently hungry—and the additional 2 billion-plus people who will live on the planet by 2050—our best projections are that crop production will need to increase between 60 and 100 percent. “Business as usual” could lead to a doubling of demand for agricultural production.
If the population is growing by less than one-third, why would the overall demand double? Simply stated: more people have more money.
Meeting the problem through production alone won’t be enough, and we should explore many alternatives that focus on reducing demand for food, like changing our diets and reducing food waste and loss. Increasing crop production can be part of the solution.
