From The Independent:

Genetically-modified crops are among measures needed to tackle problems with global food supplies that could see prices soar, leading scientists said today.

A new Government-commissioned report warned that there were major failings in the global food system that damages the environment and leaves one billion people hungry.

A further one billion suffer from "hidden hunger" in which nutrients are missing from their diet and the same number are over-consuming, while a third of all food produced is currently wasted.

From The Telegraph:

The fight is on over how to solve our food crisis, but if we choose the wrong food policy at this juncture there could be no going back, says Rose Prince.

Hardly a morning passes without food making the headlines. This week has brought us the burger that thinks it's a pizza and news that eating asparagus makes you stay slim (fingers crossed it's the type covered in melted butter). And we heard that, if you eat pickled squid guts and single cream together, it tastes like strawberry shortcake.

From Popular Mechanics:

Bamboo has come into vogue as a green, sustainable resource that's used for everything from cutting boards to clothing to wood floors. But until now, almost all of the bamboo in products sold here has come from overseas. That could change soon, as new planting techniques may lead to millions of new acres of bamboo shoots in the American South.

Could the Mississippi Delta become America's bamboo belt, the breadbasket of a new class of homegrown structural building components? Earlier this June in Greenville, Miss., a group of engineers, manufacturers, bureaucrats and farmers gathered to discuss how land formerly cultivated for cotton might be converted to produce bamboo on a massive scale. Teragren, the world's largest bamboo building products manufacturer, has engineered new structural joists made of imported Moso, a bamboo species with the tensile strength of steel. Teragren VP Tom Goodham says a domestic Moso source is the key to renewable structural timber becoming mainstream and affordable: "The whole bamboo building-products category is just on the cusp of critical mass."

From The Telegraph:

Academics have claimed that moving away from a hunter-gatherer lifestyle was 'the worst mistake in history'. But are they right?

Last week, Sir Paul McCartney urged us, amid a blaze of publicity, to curb our carnivorous lifestyles and go meat-free on Mondays, in order to reduce the damage that modern agriculture does to the planet. But for all the recent talk about the pros and cons of farming, and how the methods we use are affecting the environment, a more basic point has been missed e_SEnD that growing crops might be damaging not just to the environment but to the development of our own species. Could it be that rather than being a boon to mankind, the invention of agriculture was, in the words of one academic, "the worst mistake in human history"?

Robots Rolling Towards Farm Revolution

From The New Scientist:

From ploughs to seed drills to tractors, evolving technology has brought about radical changes to agriculture over the years. Now the sector is poised for another shift as robotic farmhands gear up to make agriculture greener and more efficient.

Three things now make mobile agricultural robots a real possibility in the near future, says Tony Stentz, an engineer at Carnegie Mellon University's robotics institute.

Firstly, mobile robots have now proved able to cope with complex outdoor environmentsMovie Camera; secondly, the price of production has fallen; and, finally, society should now see robot labourers as a benefit not a curse.

New Science Could Defeat Food Crises

From The Guardian:

Breakthroughs in microscopic engineering could boost shelf life of food and increase crop yields.

A controversial scientific revolution that could give packaged foods a dramatically longer shelf life and boost crop growth has "real potential" to help feed a fast-growing world, according to environment secretary Hilary Benn.

New developments in nanotechnology, engineering carried out at a microscopic level, could lead to plastic packaging designed to stop food and drink spoiling by killing bacteria or preventing oxygen getting through the container.

The technology could also be used to enrich food with supplements and preserve vitamins that would otherwise be destroyed as food aged. Farmers could also use it to ensure the slow release of fertilisers at the right time for crops, and to detect threats from pests or pollutants. The technology is, however, highly controversial, with green campaigners arguing that its effects on human health are unknown.

From The Guardian:

Leading scientists met last night to debate whether genetically modified crops can feed the world's hungry. The issue, it seems, is as divisive as ever

The Science Museum in London is running an exhibition until the end of May called Future Foods. It attempts to give a balanced view of the pros and cons of genetically modified crops, which are back on the agenda in the light of fears over a major food crisis. It does a good job too.

As part of the exhibition, the museum organised a debate at the Dana Centre to give the public a chance to debate GM crops and the food crisis with some key scientists. I chaired the event and picked up on a few issues I thought might be worth sharing.

Drought Resistance Is The Goal, But Methods Differ

From International Herald Tribune:

GRAND ISLAND, Nebraska: To satisfy the world's growing demand for food, scientists are trying to pull off a genetic trick that nature itself has had trouble accomplishing in millions of years of evolution. They want to create varieties of corn, wheat and other crops that can thrive with little water.

As the world's population expands and global warming alters weather patterns, water shortages are expected to hold back efforts to grow more food. People drink only a quart or two of water every day, but the food they eat in a typical day, including plants and meat, requires 2,000 to 3,000 quarts to produce.

For companies that manage to get "more crop per drop," the payoff could be huge, and scientists at many of the biggest agricultural companies are busy tweaking plant genes in search of the winning formula.

Emergence Of Agriculture In Prehistory Took Much Longer, Genetic Evidence Suggests

From Science Daily:

ScienceDaily (Sep. 20, 2008) — Researchers led by Dr Robin Allaby of the University of Warwick’s plant research arm Warwick HRI have found evidence that genetics supports the idea that the emergence of agriculture in prehistory took much longer than originally thought.

Until recently researchers say the story of the origin of agriculture was one of a relatively sudden appearance of plant cultivation in the Near East around 10,000 years ago spreading quickly into Europe and dovetailing conveniently with ideas about how quickly language and population genes spread from the Near East to Europe. Initially, genetics appeared to support this idea but now cracks are beginning to appear in the evidence underpinning that model

Now a team led by Dr Robin Allaby from the University of Warwick have developed a new mathematical model that shows how plant agriculture actually began much earlier than first thought, well before the Younger Dryas (the last “big freeze” with glacial conditions in the higher latitudes of the Northern Hemisphere). It also shows that useful gene types could have actually taken thousands of years to become stable.

How Far North Can You Grow Vegetables?

Amanda Joynt waters her garden in an old hockey arena converted to a greenhouse for growing vegetables 124 miles north of the Arctic Circle in Inuvik, Northwest Territories. The half-pipe shaped facility is North America's northern-most commercial greenhouse, and a virtual necessity for anyone interested in eating a fresh vegetable in Inuvik that has not been shipped in from a warmer climate.

Greenhouse is a necessity for anyone interested in eating fresh vegetables

INUVIK, Northwest Territories - Amanda Joynt reached down and picked a fresh tomato from the vine. That's no small feat when you are living 120 miles above the Arctic Circle in Canada's Far North.

Joynt, a resident of Inuvik is a member of the town's community greenhouse, a former ice hockey arena that has been converted into an oasis of vegetables and flowers on the permafrost.

The building, shaped like a half-pipe, is North America's northernmost commercial greenhouse, and all but a necessity for anyone interested in eating a fresh vegetable in Inuvik that has not been shipped in from a warmer climate — at a startlingly high cost.

Farming In The Sky

From Popsci.com

Agriculture is broken. Traditional techniques use too much energy and produce too little food for our growing planet. One fix: skyscrapers filled with robotically tended hydroponic crops and lab-grown meat

By 2025, the world’s population will swell from 6.6 billion to 8 billion people. Climate simulations predict sustained drought for the American Midwest and giant swathes of farmland in Africa and Asia. Is mathematician Thomas Malthus’s 200-year-old prediction, that human growth will one day outpace agriculture, finally coming to pass? Advances in farming technology have kept us fed so far, but the planet’s resources are tapped.

The choice is clear—rethink how we grow food, or starve. Environmental scientist Dickson Despommier of Columbia University and other scientists propose a radical solution: Transplant farms into city skyscrapers. These towers would use soil-free hydroponic farming to slash demand for energy (they’ll be powered by a process that converts sewage into electricity) while producing more food. Farming skyward would also free up farmland for trees, which would help remove carbon dioxide from the atmosphere. Even better, vertical farms would grow food near where it would be eaten, thus cutting not only the cost but the emissions of transportation. If you include emissions from the oil burned to cultivate and ship crops and livestock in addition to, yes, methane from farm-animal flatulence, agriculture churns out nearly 14 percent of the world’s greenhouse-gas emissions.
