This study suggests just that.
The study by scientists at the University of Nebraska-Lincoln argues that there have been abrupt declines or plateaus in the rate of production of major crops which undermine optimistic projections of constantly increasing crop yields.
Seems corn, grain, and rice production has reached it limits with no serious increases over the past decade...
A concern is that despite the increase in investment in agricultural R&D and education during this period, the relative rate of yield gain for the major food crops has decreased over time together with evidence of upper yield plateaus in some of the most productive domains.
It also criticizes most other yield projection models which predict compound or exponential production increases over coming years and decades, saying these do not occur in the real world. And that such growth rates are not feasible over the long term because average farm yields eventually approach a yield potential ceiling determined by biophysical limits on crop growth rates and yield.
And goes on to say that five decades of perpetually increasing crop yields were driven by rapid adoption of technologies that were largely one-time innovations
The new research raises critical questions about the capacity of traditional industrial agricultural methods to sustain global food production for a growing world population.
And according to other links attached to the news release on the study, food production will need to increase by about 60% by 2050 to meet demand and also suggests that from another report that agro ecology based on sustainable, small-scale, organic methods could potentially double food production in entire regions facing persistent hunger, over five to 10 years.
