Global food production has increased steadily over the past 60 years.

Nearly 10 billion people are expected to live on Earth by 2050, so agricultural production will become increasingly important to feed the growing population.

Much of the growth in food production over the past six decades has come from technological advances, including the development and widespread use of better crop varieties. But some studies suggest that growth in production has stalled, raising concerns about future food shortages, especially in low- and middle-income countries with the highest population growth rates.

In the new study, the researchers developed standardized measures. Using a comprehensive calorie-based index of production and yield for 144 crops, covering 98% of global agricultural land and food production, the study found that overall, global yield growth—a key indicator of agricultural productivity—has not slowed over the past six decades.

These measures could allow scientists and policymakers to compare agricultural productivity across different countries and regions. The researchers also found that any slowdowns observed in particular crops, regions or countries were offset by increases elsewhere.

“This steady growth is equivalent to an annual increase of about 33 kg of wheat per hectare, indicating continued yield gains worldwide,” the researchers added.

While the study’s findings appear credible from a global food supply perspective, the researchers warn that sustainable food production and food affordability will continue to be challenges to global food security. These concerns are especially acute, the researchers stress, given the accelerating effects of climate change and rising food demand due to rising populations and incomes.

The study is the result of a collaboration between the World Bank and the University of Idaho, USA.
