Media Claims Global Crops Shrinking As Harvests Set Records

africa crop growingAmong its top search results today for “climate change,” Google News is promoting a story published by Courthouse News Service claiming climate change has caused a dramatic decline in farm productivity.

However, data from the United Nations Food and Agriculture Organization (FAO) show that crop production and yields are consistently growing and setting new records almost every year.

Modestly warming temperatures and increased carbon dioxide concentrations have stimulated a greening of the earth that has enormously benefited agriculture.

The Courthouse News Service story, titled “Climate Change Putting a Damper on Global Food Production,” cites research produced using dubious computer models to speculate how much food would have been produced absent increased carbon dioxide levels and modestly warmer temperatures over the past half-century.

Courthouse News Service should have looked at some actual data.

“Despite continuous technological advancements, global farming productivity has dropped an average of 21% since 1961 because of climate change,” writes Courthouse News Service, summarizing the results of the computer model simulations. “That’s like losing seven years of productivity gains in the last 60 years.”

In particular, the researchers claim climate change has hit warmer regions particularly hard, reducing agricultural productivity in Africa, Latin America, and the Middle East between 26 and 34 percent.

Data from the FAO show this is false, globally and for most crops in most countries. Yields of the most important cereal crops have increased dramatically over the past few decades, repeatedly setting new records.

As shown in the chart below, the FAO’s recent “Cereal Supply and Demand Brief” reports new global records are being set nearly every year for the production of cereal crops (corn, wheat, rice, and similar crop staples) that comprise most of the global food consumption.

Courthouse News Service tried to downplay FAO’s data by falsely asserting, “Previous studies … are of limited value in assessing worldwide agricultural productivity as cereal crops only account for around 20% of global food production.”

The “Big Three” cereal crops, corn, rice, and wheat, by themselves, comprise 66 percent of global human food consumption. Indeed, cereal crops alone make up nine of the 15 crops that provide 90 percent of humanity’s food energy intake.

Other crops have also benefited from longer growing seasons, fewer late-season frost events, and the carbon dioxide fertilization effect.

Data presented in The Heartland Institute report, “The Social Benefits of Fossil Fuels,” demonstrate the “increase in atmospheric [carbon dioxide] concentration … caused by the historical burning of fossil fuels has likely increased agricultural production per unit [of] land area by 70 percent for C3 cereals [which include rice, wheat, oats, cotton, and evergreen trees], 28 percent for C4 cereals [which include sorghum, maize, and various grasses], 33 percent for fruits and melons, 62 percent for legumes, 67 percent for root and tuber crops, and 51 percent for vegetables.”

Also, contrary to the claims made in the Courthouse News Service article, the increase in food production has been widespread, with crop production increasing in developed countries and developing countries alike, and in temperate and warmer regions alike.

Previous Climate Realism posts show agricultural productivity has increased dramatically, for example, in Africa, here, here, and here; in the Middle East, here and here; in Latin America, here, here, and here; in Asia, here, here, and here, and in North America, here, here, here, here, and here.

This increase in food production has occurred even as the number of people and the amount of land devoted to growing crops has declined. Fewer people, farming less land and producing higher yields reflect increasing rather than declining productivity.

Rather than uncritically parroting one group of researchers’ flawed claims concerning falling crop yields, Courthouse News Service should have done a little independent fact-checking.

Had it done so, it could easily have found the truth that farm productivity has increased during the recent period of modest warming.

This good news would have served its readers’ interests better than the falsehoods it published about declining farm productivity.

    And like the corrupt toadies big media has become, they will lie even better when woke policies fail and people are starving.

    Civilisation allowed this to happen. So many are now so far removed from agriculture that the failure to understand basic principles of agricultural production is commonplace. This then feeds back into political pressure that sees even conservative, experienced, agricultural science majors etc swallowing the catastrophist propaganda hook, line and sinker.

    I actually believe it is possible for those who have farmed in the same location for many decades to notice the increasing plant growth without recourse to statistics. All one needs to do is to remove the blinkers and see the growth for what it is.
