Food demand predictions could be inaccurate

Food demand predictions could be inaccurate thumbnail

The widely held view that food production needs to double by 2050 to feed a growing world population may be inaccurate.

In a study published in the journal Bioscience, researchers from Penn State’s agriculture college have challenged that view, saying the required increase may be as high as 70 per cent — or as low as 25 per cent.

Mitch Hunter, a doctoral student in agronomy, says the analysis shows that production needs to keep increasing, but not as fast as many have claimed. That’s important because it means there can be more opportunity to protect the environment, he says.

“In the coming decades, agriculture will be called upon to both feed people and ensure a healthy environment,” said Hunter. “Right now, the narrative in agriculture is really out of balance, with compelling goals for food production but no clear sense of the progress we need to make on the environment.”

A review of recent trends in agriculture’s environmental impacts shows that they are increasing and must drop dramatically to maintain clean water and stabilize the climate, according to the researchers.

More clearly defining targets, the researchers say, will clarify the scope of the challenges that agriculture must face in the coming decades, focusing research and policy.

“Food production and environmental protection must be treated as equal parts of agriculture’s grand challenge,” says study co-author David Mortensen, professor of weed and applied plant ecology, Penn State.

These new findings have important implications for farmers. Lower demand projections may suggest that prices will not rise as much as expected in coming decades.

    Well dooma,

    Thanks to you, it would appear that 23 million Australians have now joined the ranks as living, breathing, and dying, anti-Americans.

    I’m sure that Davy, the true American patriot, will be around later in the morning to make it all official.

    BTW: Cloggie. I’m from Germany. My 14th generation German ships captain left there for America and settled in Penn’s Woods in pre-U$A (1734). Pics not necessary unless you cannot read. I still have enough original genes to look German. My last name is German. I am just carrying on the family tradition of relocating to a better country when possible.

    I know your story and I tend to believe it. It is just that usually “German” is another word for “loyalty”. That you hate Washington is just fine. But that total absence of loyalty towards your own people, that puzzles me.

    Who is the Makati1 imposter? Davy? No he isn’t intelligent enough. The real makati1 doesn’t have caps, just small letters. LMAO

    You should not have stressed too much your German ancestry. There is an imposter here who freaks out on all things German. And no, it ain’t Davy. Let alone me.

    P.S. glad to be off your ignore list, once again.lol

    Davy Davy Davy, you are like a stuck record. I already agreed that what we have done in bed with China would make a porn director blush. But show me a country that hasn’t?

    Australian contribution to the last Eurovision Song Festival Contest. Says it all:

    Cloggie, You are making more sense lately. I like to pick on Davy, but he is off the deep end and I have to pass on his remarks. They always devolve into name calling or some low level shit. He writes long bullshit pieces like he is trying to prove he is intelligent or something. He should be using that time to make his farm more resilient.

    First, I do not hate America. I hate what it has become. What it represents. What is is doing to the rest of the world. I hate to see it slide into the 3rd world as it is doing. I fear it will start a nuclear war in desperation. I love no country. I love life and a beautiful sunset. ‘Patriotism’ is just another tool of the elite to keep the masses under their boot.

    Second, China is not looking for a province. Not the Philippines or Australia or any other country. It is looking for trade and the preservation of China, just as Russia is looking to preserve Russia. Neither want to dominate the world like the U$ does with it’s 800 military posts. Both are powerful enough to resist pressure from the Empire, and that is a good thing.

    Gee, did I call out an asshole? I always know when my point sticks because a dumbass steps up and whines. Look dooma, all you do is come on this board from time to time to show your hate for the US. Rarely do you contribute useful info. You do your anti-American criticism in a sloppy and poor way. If you are going to be anti-American then do it right or I am going to call you out. Show a little respect and show you know what you are talking about. I could give a shit about your hurt feelings because you are just a dumbass whiner. You are intellectually lazy and lack skills of understanding which is obvious from your lame rants. You are more about expressing your hate of yourself and life in a projection on to something other than you and your country. Yea, you hate Australia but you blame that hate on the US. You are just another dime a dozen anti-American Anglosphere dumbasses on this board who hate who they are and want to blame someone else for it.

    I am US critical. I am not happy with the Empire nor the culture. I do not praise the US. I am looking for answer and trying to make my way through the bullshit called modern life. What I am not going to stand for is idiots like you that want to blow smoke up my ass that this civilization coming apart is all my fault as an American. There is no reason to respond to your lame rant above. It is just a collection of more of the same I see daily here. Your country is a failure too so get over it. Be part of the solution not the problem. Show some backbone and look at what and how you contributed to this mess and that will show you how you can do something constructive not useless sniffling whining.

    Makati, I have a pedigree as old as you. My dad’s mom had some blood from before the American Revolution. In this line one of my ancestors was in the Rogers Rangers and fought the French and Indians in the Seven Years War in the 1750’s. Her grandfather was a steamboat pilot in St Louis. My dad has done his paternal line back to Moravia in the current Czech Republic back to the 1500’s. They were farmers who lived near Frýdek-Místek. We spent some time in France following the battle of Austerlitz. We think our family followed Napoleon back to France. They left France in 1849 from La Havre and made land fall in New Orleans. My great, great, great grandfather then traveled up the Mississippi to St Louis and live with a then significant Czech immigrant population. My mom’s side is from what was once Prussia. We have that line traced back into the early 19th century.

    My dad was big on family trees before they were the in thing in the US. I remember as a kid my dad taking me to the city library where he looked through census reports and other info. He took me to old houses and took pictures. In the eighties we went back to Czechoslovakia when it was still communist. We found family there. We also found French family who live in Lorain. It made an impression on me and I became very interested in history because of it.

    Who cares makati about our pedigree. Yea, it is important to us personally but do we need to try to impress the board? No, being a braggart is not contributing. Why do you have to be such a braggart? What is it about you that seeks to talk down others and talk up yourself? If I talk down others like you it is because you have attacked me. I never attack people that show respect. You are the biggest blemish on this board spreading half-truths and manipulated facts. You do this to satisfy a hatred of a country where you had a failed life. You are neurotic about it because your family is there and you must feel some pain from hating what they are. You must feel some guilt for leaving them. I am not going to desert my family because I am afraid of dying and ashamed of myself. I am going to make a stand here and protect them as a patriarch should. You are just a failure and try to mask over that by being a braggart.

    Der Spiegel is promoting US invented (entrepreneur David Rosenberg) vertical farms or Aero-Farms. No soil, just water and plastic wool with nutrients and artifical light, causing very rapid growth:

    http://www.spiegel.de/wirtschaft/service/gemueseanbau-in-etagen-pflanzenfabrik-statt-gewaechshaus-a-1137156.html

    …resulting in a vegetable factory. Uses 95% less water and no pesticides, fungicides or herbicides. Production is intended purely for the local community, without transportation.

    AeroFarms is planning two dozens new facilities.

    Original inventor was Dickson Despommier, who for decades taught at Columbia University in NYC.

    This could be the solution for large cities to survive and avoid long transportation lines. But only if energy required for transport is much larger than energy required for artificial light.

  9. Davy on Sat, 11th Mar 2017 5:55 am 

    Clog, even if this type of farming was economic which it isn’t when one considers total lifecycle costs, what is required for nutrition is so much more than what aero-farms can provide. Much of our diets today are grain, fruit, and meat related. We are not going to survive on vegetables. This is also something preppers need to realize when they think of survival. Their gardens are not going to cut it. It takes a community with many different participants producing various important products to a mix of staples. A real localized agricultural community is a carbon and nitrogen cycle revolving around all the food groups. Then there are the participants who process and preserve this food. The way we did these things in the 18th and 19th century is the future not your techno-optimistic jetsons fiction.
