Unexpected Strawberry Crop Spins Burkina’s ‘Red Gold'

In the suburbs of Burkina Faso's capital Ouagadougou, lucrative strawberry farming is supplanting traditional crops like cabbage and lettuce and has become a top export to neighboring countries.

Prized as "red gold" in the Sahel, strawberry crops brought in some 2.0 billion CFA francs ($3.3 million) from 2019 to 2020, according to agricultural support program PAPEA.

In their January to April season, strawberries "take the place of other crops", Yiwendenda Tiemtore, a farmer in the working-class Boulmiougou district on the city outskirts, told AFP.

Tiemtore has been busy harvesting the red fruit since dawn, before temperatures rise to 40 degrees Celsius (104 degrees Fahrenheit).

He harvests about 25 to 30 kilograms (55-66 pounds) of Burkina's popular strawberry varieties, "selva" and "camarosa", every three days, watering his plots from wells.

Cultivating strawberries, which thrive on ample sunlight and water, might come as a surprise in this semi-arid West African country.

But Burkina Faso leads the region's strawberry production, growing about 2,000 tons a year.

Despite being prized by local customers, more than half is exported to neighboring countries.

"We receive orders from abroad, particularly from Ivory Coast, Niger and Ghana," said market gardener Madi Compaore, who specializes in strawberries and trains local growers.

"Demand is constantly rising and the prices are good."

In season, strawberries tend to be sold at a higher price than other fruit and vegetables, fetching 3,000 CFA francs ($5.0) per kilogram.

Production has remained strong despite insecurity in the country, including from extremist violence and the repercussions of two coups in 2022.

As well as in Ouagadougou, strawberry production is prominent in Bobo-Dioulasso -- Burkina's second city -- even though "the sector's not very well organized" there, Compaore said.

Since the 70s

"You might think it's an oddity to grow strawberries in a Sahelian country like Burkina Faso but it's been a fixture since the 1970s," Compaore added.

The practice began when a French expatriate introduced a few plants to his garden in the country. Now more and more people are growing them.

"It's our red gold. It's one of the most profitable crops for both growers and sellers," he explained.

Seller Jacqueline Taonsa has no hesitation in swapping from apples and bananas to strawberries in season.

"With the heat, it's hard to keep strawberries fresh for long," said Taonsa, who cycles around Ouagadougou neighborhoods balancing a salad bowl on her head.

"So we take quantities that can be sold quickly during the day," she explained. That usually amounts to about five or six kilograms.

Adissa Tiemtore used to be a full-time fruit and vegetable seller.

She has mainly switched to selling woven loincloths now but takes up her strawberry business again in season because of the lucrative margins, as high as "200 to 300 percent".

"I start strawberry selling again when they're in season to make a bit of money and satisfy my former customers, who continue to ask for them," she said.

"We go round the different growers depending on what day they're harvesting. That way we get enough to sell every day during the three fruit-producing months," she said.

The end of April spells the end of the bonanza. "We go back to our other activities and we wait for next season," Tiemtore said.



These Canadian Rocks May Be the Oldest on Earth

Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada.

The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks — plains of streaked gray stone on the eastern shore of Hudson Bay in Quebec. But researchers disagree on exactly how old they are.

Work from two decades ago suggested the rocks could be 4.3 billion years old, placing them in the earliest period of Earth's history. But other scientists using a different dating method contested the finding, arguing that long-ago contaminants were skewing the rocks' age and that they were actually slightly younger at 3.8 billion years old.

In the new study, researchers sampled a different section of rock from the belt and estimated its age using the previous two dating techniques — measuring how one radioactive element decays into another over time. The result: The rocks were about 4.16 billion years old.

The different methods "gave exactly the same age,” said study author Jonathan O'Neil with the University of Ottawa.

The new research was published Thursday in the journal Science.

Earth formed about 4.5 billion years ago from a collapsing cloud of dust and gas soon after the solar system existed. Primordial rocks often get melted and recycled by Earth's moving tectonic plates, making them extremely rare on the surface today. Scientists have uncovered 4 billion-year-old rocks from another formation in Canada called the Acasta Gneiss Complex, but the Nuvvuagittuq rocks could be even older.

Studying rocks from Earth's earliest history could give a glimpse into how the planet may have looked — how its roiling magma oceans gave way to tectonic plates — and even how life got started.

“To have a sample of what was going on on Earth way back then is really valuable,” said Mark Reagan with the University of Iowa, who studies volcanic rocks and lava and was not involved with the new study.

The rock formation is on tribal Inukjuak lands and the local Inuit community has temporarily restricted scientists from taking samples from the site due to damage from previous visits.

After some geologists visited the site, large chunks of rock were missing and the community noticed pieces for sale online, said Tommy Palliser, who manages the land with the Pituvik Landholding Corp. The Inuit community wants to work with scientists to set up a provincial park that would protect the land while allowing researchers to study it.

“There's a lot of interest for these rocks, which we understand,” said Palliser, a member of the community. “We just don't want any more damage.”
