ANTS MASTERED AGRICULTURE 30MILLION YEARS BEFORE WE DID.

Ants cultivated designer crops in controlled environments millions of years before humans figured out how to push seeds into the ground to grow food, scientists reported in a study Wednesday.


It has long been known that dozens of ants species tend and harvest fungi in sub-terranean farms, mostly to feed a colony’s larvae.

A few species have taken that process to the next level, modifying fungi so thoroughly they can no longer survive in the wild, much in the way some genetically altered crops consumed by humans are not viable without pesticides or other inputs.

“Over the course of millions of years, the fungus has become domesticated,” said lead author Michael Branstetter, an ant specialist at the US National Museum of Natural History.


The new research shows for the first time that some ants transitioned to this more sophisticated level of farming about 30 million years ago, probably in response to a cooling and drying climate.
“We discovered that domestication likely occurred in dry habitats in South America,” Branstetter told AFP.

“These habitats would have prevented the ant’s fungi from escaping the nest and interbreeding with other free-living fungi.”

Moisture-loving fungi evolved in wet forests, and would have been poorly equipped to survive on their own in this changing environment.

The findings, published in the journal Proceedings of the Royal Society B, are the fruit of intense genetic sleuthing.

Using powerful new tools, scientists compared some 1,500 stretches of DNA in 119 modern ant species, two-thirds of them farming ants.

By identifying the non-farming ant most closely related to the fungi-cultivating species, they were able to construct an evolutionary tree going back in time.

“Higher agricultural-ant societies have been practising sustainable, industrial-scale agriculture for millions of years,” said lead researcher Ted Schultz, the museum’s curator of ants.

There may be lessons there for our own species, he added.

“They provide all the nourishment needed for their societies using a single crop that is resistant to disease, pests and droughts at a scale and level of efficiency that rivals human agriculture,” he said in a statement.

Just as humans living in a dry or temperate climate might raise tropical plants in a greenhouse, agricultural ants carefully maintain the humidity within their climate-controlled fungal gardens.
“If things are getting a little too dry, the ants go out and get water and they add it,” Shultz explained. “If they’re too wet, they do the opposite.”

Fungi, which include yeasts and moulds, are neither plants nor animals, but form a “kingdom” of their own. BY AFP.

AGRICULTURE IS AN ALTERNATIVE TO OIL SAYS OSHOFFA.

• Oyedepo Tasks Nigerians On Agric Innovations
The Pastor and Spiritual Head, Celestial Church of Christ, worldwide, Rev. Emmanuel Mobiyina Oshoffa, has assured Nigerians that the nation will certainly overcome the current economic recession so long they get connected to God.

Oshoffa, who spoke at the unveiling of the logo for the 70th Anniversary of the Church, which held at Makoko, said God loves the nation and if only Nigerians could trust in Him and believe in His sovereign power, the nation would certainly come out of the woods.

The Cleric also advised leaders to seriously consider an option to oil, which has been generally acknowledged to be agriculture. Speaking on spiritual matters and the state of the church, Oshoffa said: “Every member of the Church is called to follow the teachings of the Lord Jesus Christ on love and oneness. This Church is to be one throughout the world. It is set up to cleanse the world, as well as cleanse the spirit and the body.

“Anybody who accepts that Jesus Christ is the Son of God is a true child of God, who will experience joy and peace with no darkness in his life.

In his comment, the Chairman, Central Planning Committee for the anniversary, Prophet Emmanuel Soyemi said: “We are aiming at one Church, and one leader under the leadership of Rev. Emmanuel Mobiyina Oshoffa and time has come to return to the foundation, laid by the founder, Pastor S.B.J. Oshoffa with the goal of bringing the Church back to the basics, so that the glory of God will return to it.

In the same vein, the Chancellor, Landmark University, Dr. David Oyedepo, has called for innovative thinking in product development and agricultural enterprise towards addressing food deficit in the country.

He made the call, Thursday, at the 6th Founder’s Day Anniversary of the university.  Oyedepo, who was represented by the Vice-Chancellor, Professor Aize Obayan, said there was neither substitute for food nor known software for addressing food challenges, except breakthroughs in the information technology development.

NO CONFLICT OF INTERESTS ON PESTICIDE ADVICE.

The assertion by Professor Dave Goulson (Farmers could slash pesticide use without losses, research reveals, 6 April) cannot go unchallenged. He says that pesticides are massively over-used because farmers are advised by agronomists working on commission to sell products.


The Agricultural Industries Confederation represents the majority of businesses that supply both agronomy advice and crop protection products to UK farmers. Farmers can elect to pay separately for agronomy advice and crop protection products. Farmers also have access to information from agrochemical manufacturers as well as independent agronomy research organisations – much of it free online. In many instances, those delivering advice do not receive commission.


The UK crop protection industry is focused on ensuring optimum, rather than maximum, use of crop protection products to ensure the farming industry delivers safe, wholesome and affordable food. It is a legal requirement that agronomists selling crop protection products are highly trained and kept up to date with agronomic developments to deliver advice to ensure efficient production and environmental protection. NEWS FROM AROUND THE WORLD.

YOUNG MIDWESTERN FARMERS WANT TO GROW SUSTAINABLE FOOD BUT THEY NEED HELP.

On a recent chilly afternoon, Natasha Hegmann, 28, and her husband, Pete Kerns, 27, tended the fire of a giant copper boiler holding some 250 gallons of maple sap. The sap had flowed into the boiler overnight through a series of pipes from nearby trees. Turning the gooey sap into syrup will take days.

A native Iowan, Hegmann worked at a number of local community farms before her and Kerns set up their own, Turkey River Farms, in 2015 to grow vegetables in warmer months and harvest maple sap during the winter. The couple thought about farming in other states but ultimately decided to stay in Iowa because of the support given by Practical Farmers of Iowa (PFI), a 32-year-old nonprofit that aims to attract new and young farmers to the field and teach them to grow food organically. The group offers workshops and a program that gives funds to match the money saved by new farmers over a period of time.

“PFI has been huge for us,” Hegmann says. “It’s actually part of the reason that we chose to settle and start our farm in Iowa.”

For decades, the midwest  has boasted the highest concentration of farms in the US, and is also a crucial agricultural region, both for local food production and food that is exported. Today, midwestern states, particularly Iowa, are the second leading producers of crops and livestock behind California, according to the US Department of Agriculture (USDA) census. This says a lot about the midwest’s potential for being the next sustainable food production hub in the US.

But here’s the trouble: statistically, young people just aren’t that into farming. In the most recent USDA agricultural census, new farmer numbers dropped by around 20% between 2007-2012, with the majority of farmers falling somewhere between the ages of 55-64, consistent with a 30-year trend. The culprits of this trend: a diminishing ability to subsist on farming income, an increase in debt needed to farm and general rural poverty.

Young people are leaving the midwest faster than anywhere else. “Farming is also not on the typical list of ‘hot’ careers for twenty-somethings, and the barriers to entry can seem daunting,” says Gary Adamkiewicz, assistant professor of Environmental Health and Exposure Disparities at Harvard University.

One of the biggest roadblocks for beginning farmers is land access. Land costs continue to climb and, despite the enormous land transference to come as older farmers retire – 70% of the nation’s farmland over the next two decades – most of it may not end up in the hands of willing young farmers but in the hands of property developers.For farmers just cutting into the market, starting small, and wanting to grow sustainably, the odds are not great. Large farms have the scale, money and freedom to use synthetic pesticides and fertilizers to maximize yields. Organic farming, on the other hand, can be more profitable but takes more land to grow the same amount of food as conventional farming. Farmers are limited in the types of chemicals they can use to get rid of pests and nurture crops, and organic certification is long and expensive. The USDA requires farmers to demonstrate organic practices for three years before they can be certified – but farmers are not allowed to increase the prices of their products during this time to be on par with other organic produce.

Hannah Breckbill has faced these challenges. The 29-year-old owner of Humble Hands Harvest near Decorah, Iowa, runs a two-woman operation growing organic vegetable produce. “Access to capital is a lot harder with unconventional agriculture, but the capital needs are not a lot less,” she says. Her biggest challenge? Land. “I’ve been able to manage that through creative means, renting and borrowing from landowners who had a few acres to spare. Now I’m finally buying my own land, and that had to happen by creative means too: lots of people in my community gifting me with substantial amounts of money and capital.”

Breckbill says that she’s spent almost $100,000 on Humble Hands Harvest since starting the operation in 2013. Her first year required around $12,000 to run the farm on land she didn’t have to buy at the time. Later, the eight acres she is on now cost $40,000 – some was gifted, some was through a $20,000 loan from her uncle. Electricity cost a further $10,000 and the greenhouse a little over $8,000. Operating costs are roughly around $10,000 per year, not counting labor costs.
Fortunately for Breckbill and other young farmers in the midwest, organizations like PFI help relieve the burden. The Midwest Organic and Sustainable Education Service (Moses) is a nonprofit formed in 1999 that aims to help out farmers in the upper midwest with resources, workshops, and education on all sorts of farming-related subjects, from fieldwork to financial.

The nonprofit’s biggest contribution: an annual educational farming conference, held in Wisconsin. This year’s event, held in February, drew 3,100 attendants hailing from 49 different states and six foreign countries; 44% of them designated themselves as new or beginning farmers (in other words, farming less than ten years) – a rise from the 42% since 2016. Moses designates specific workshops for new farmers as part of its New Organic Stewards program, including education on topics from practical sustainable farming skills to financial tools.There’s also the Land Stewardship Project (LSP), a Minnesota nonprofit that provides training workshops and courses throughout the state for new farmers, designed to help equip new farmers with business planning skills so they can then run their own profitable agricultural businesses.

According to LSP, farm startup costs tend to average around $60,000 (whether for livestock, a diversified crop of vegetables, or fruits) and may include greenhouses, electricity, coolers for food storage, tractors, equipment, fencing and more. Planting orchards or a mix of vegetables tends to have much higher startup costs, even when on smaller acreage; livestock is relatively lower, even on land close to 50 acres. However, this number does not include the price of land, which varies widely depending on location.

More than 600 farmers completed a beginner’s farming course in the first 16 years of the nonprofit’s initiative, according to LSP. There’s also a two-year mentorship program that pairs new farmers with established and profitable farms in the area. Breckbill happened to benefit from LSP’s programs. “I did my first business planning through LSP, and I continue to work with them,” she says.The beginner’s farming course has even formed its own nationwide collaborative, spawning its own website and splinter programs that model the original program piece-for-piece in South Dakota, North Carolina, Illinois, Kentucky and Missouri

To address the problem of land, an Iowa organization called Sustainable Iowa Land Trust, or Silt, was established 2014. Modeled closely after other land trusts around the country, the nonprofit protects land purchased or donated to the trust with conservation easements, which are legal agreements that prohibit the land from being developed for business use other than farming.

As a result of placing the land in conservation easement, its value is depreciated – due to it no longer being on the market for development – making it an affordable lease option for new farmers. Silt also helps with organic certification and doesn’t allow farmers to grow high cash conventional crops, such as corn for ethanol – just food. “We set a higher bar in our easements than almost any land trust,” says Suzan Erem, president of Silt.

Erem feels a sense of urgency about carrying out Silt’s mission. “We have a window of opportunity, but if young people don’t keep stepping up to do this labor intensive, somewhat risky form of farming, none of us will have any choices left.”

Adamkiewicz at Harvard agrees. “Last year, the USDA announced a series of initiatives aimed at cultivating the next generation of farmers, including mentoring and loan programs. We need more investments like these.

“We need to train this next generation who are trying to make a difference while dealing with some of the stresses already put on farmland by conventional agriculture.” BY ADRAIN WHITE.
