Grow Faster, Grow Stronger: Speed-Breeding Crops to Feed the Future
Farmers and plant breeders are in a race against time. The world population is growing rapidly, requiring ever more food, but the amount of cultivable land is limited. Warmer temperatures have extended growth seasons in some areas — and brought drought and pests to others.
"We face a grand challenge in terms of feeding the world," said Lee Hickey, a plant geneticist at the University of Queensland in Australia. "If you look at the stats, we're going to have about 10 billion on the planet by 2050 and we're going to need 60 to 80 percent more food to feed everybody. It's an even greater challenge in the face of climate change and diseases that affect our crops that are also rapidly evolving."
[...] Dr. Hickey's team has been working on "speed breeding," tightly controlling light and temperature to send plant growth into overdrive. This enables researchers to harvest seeds and start growing the next generation of crops sooner.
Their technique was inspired by NASA research into how to grow food on space stations. They trick the crops into flowering early by blasting blue and red LED lights for 22 hours a day and keeping temperatures between 62 and 72 degrees Fahrenheit. Last November, in a paper in Nature [DOI: 10.1038/s41596-018-0072-z] [DX], they showed that they can grow up to six generations of wheat, barley, chickpeas and canola in a year, whereas traditional methods would only yield one or two.
On Monday in Nature Biotechnology [DOI: 10.1038/s41587-019-0152-9] [DX], Dr. Hickey and his team highlight the potential of speed breeding, as well as other techniques that may help improve food security. Combining speed breeding with other state-of-the-art technologies, such as gene editing, is the best way to create a pipeline of new crops, according to the researchers.

Nothing wrong with effort towards making production more efficient, but what if we didn’t throw away so much food in the first place? Any effort to produce more just gets halved by the volume wasted.

I was coming to say something to that effect but you beat me to it. Globally speaking, we already produce enough to feed the entire planet. It's the distribution that's the problem plus, for lack of a better term, "cost effiency." It's an insanely complicated situation, far too big for my little head. How do you feed the world while still making it worthwhile for farmers? According to this article [edagricole.it] (in Italian) Sicilian citrus farmers get under €0.10 per Kg but, including the cost of harvesting and transport, the production cost is easily over €0.12! How do you feed the world instead of throwing away 1/3 of crops produced? [fao.org]
It's up to you, eggheads!

If you think there's no problem eating someone's mixed up leftovers off their plate what's your objection to eating it after it's thrown away? It's still edible food to you right?
If you don't, what's stopping you? Very similar reasons to why the food is thrown away in the first place?
