Without immediate action and a global shift in priorities, the world will not be able to feed its growing population in the coming decades, according to a new report from a United Nations panel. The UN Secretary General’s High-level Panel on Global Sustainability released its report, titled “Resilient people, resilient planet,” this week.

The report’s authors note that the world’s population is likely to grow to nearly 9 billion by 2040 from 7 billion now. Also, the number of middle-class consumers will increase by 3 billion over the next 20 years, creating rapid growth in global food demand. By 2030 the world will need at least 50 percent more food, 45 percent more energy and 30 percent more water, according to the report.
