San José (United States) (AFP) - The acceleration in climate change and its impact on agricultural production means that profound societal changes will be needed in coming decades to feed the world's growing population, researchers at an annual science conference said.
According to scientists, food production will have to be doubled over the next 35 years to feed a global population of nine billion people in 2050, compared with seven billion today.
Feeding the world "is going to take some changes in terms of minimizing climate disruption," said Jerry Hatfield, director at the National Laboratory for Agriculture and the Environment.
Rainfall volatility, increased drought and rising temperatures affect crop yields, which means action must be taken, he said during a talk Sunday at the annual meeting of the American Association for the Advancement of Science.
"If you look at production from 2000 to 2050, we basically have to produce the same amount of food as we produced in the last 500 years" he said.

After Hansen, Jones and Mann, it’s no wonder scientific PHDs garner little respect and even less credibility.
Something is wrong with the basic math behind this assertion.
Why would you need a 100 percent increase in food production to feed a population increase of only 28.5 percent?
I wonder where all the corn would be consumed if not for ethanol...
There is a famine coming but it’s not due to global warming. It’s going to be due to government policies. Remember the pale horse of Revelation.

If it gets rough enough, things will be much better afterwards. Those who are humble enough to do so will try gardening. It can be much more efficient in terms of using less space and water than farming operations done by global firms.
Claim April 1970: “If present trends continue, the world will be … eleven degrees colder by the year 2000. This is about twice what it would take to put us in an ice age.” Kenneth E.F. Watt, in Earth Day, 1970.
Claim 1972: “Artic specialist Bernt Balchen says a general warming trend over the North Pole is melting the polar ice cap and may produce an ice-free Arctic Ocean by the year 2000.” Christian Science Monitor, June 8, 1972.
Claim 1989: “Using computer models, researchers concluded that global warming would raise average annual temperatures nationwide two degrees by 2010.” Associated Press, May 15, 1989.
Claim: “[By] 1995, the greenhouse effect would be desolating the heartlands of North America and Eurasia with horrific drought, causing crop failures and food riots … [By 1996] The Platte River of Nebraska would be dry, while a continent-wide black blizzard of prairie topsoil will stop traffic on interstates, strip paint from houses and shut down computers.” Michel Oppenheimer and Robert H. Boyle, Dead Heat, St. Martin’s Press,
Hmmm, scientists, not the most reliable when it comes to predictions.
Acres in corn had been dropping for decades before fuel ethanol. Dropping fuel ethanol would likely reduce corn acres at least 25% in a couple years. Corn acreage reduction would continue.
Pork, chicken and egg prices would likely rise because fuel ethanol currently subsidizes cheap high-protein animal feed.
Soybeans, hay, wheat, cotton, milo and rice would be gainers. Specialty crops would gain too.
Obviously these "scientists" are not mathematicians.
The media told us that 2014 was the hottest year on record.
Both corn and soybean crops were records in 2014 for the US.
Well, if CO2 is increasing as much as the climate wild-hairs claim, then that’s GOOD for food production!
But, I want a famine.
There is going to be a famine. It will be from cooling due to volcanism or a meteor impact. People will have hungry children, and the vote will suddenly be much more conservative. Many dumb and lazy people will die.
I remember hunting pheasants on set aside land, now supporting corn fields.
