Coronavirus Crisis Fuels Interest In Vertical Farming

The coronavirus pandemic has been a major worry for many British farmers, threatening access to agricultural labor and complicating international supply chains. But for proponents of indoor farming, the crisis has offered an opportunity.
David Farquhar, chief executive of technology developer Intelligent Growth Solutions, says the pandemic has prompted a spike in interest in ‘vertical farms’, where batches of crops can be individually watered, fed and lit using LED lights, allowing them to be grown year-round with minimal labor near their markets, regardless of local soil or weather conditions.
At the company’s demonstration farm in Invergowrie near the Scottish city of Dundee, trays of produce stacked in 9 meter-tall towers are managed remotely from seeding to packaging. Humans only need to enter the towers for occasional maintenance. “You can run it entirely on robotics . . . You probably need to go in once every six months,” Mr. Farquhar said.
This higher productivity will have particular appeal to British farmers, who are facing a steep increase in costs because coronavirus restrictions have affected the arrival of seasonal workers from eastern Europe. Brexit may also make it more difficult to access labor from the bloc when the UK’s transition period expires at the end of the year.
Colin Campbell, chief executive of the James Hutton Institute, a research organization that hosts the IGS farm and another vertical farming company, Liberty Produce, said the global food supply system had generally worked well during the pandemic. But he added that the crisis had highlighted worries about food safety and the risks of relying on seedlings or produce grown far away from where it is consumed. “Covid-19 is making a lot of people rethink how we want to grow our food,” he said.

Clima - Digital Publication and Podcast Launched by Agritech Specialist, IGS
Thought leadership brought to you by IGS. Sustainable Food Security - is a global supply chain a thing of the past?
Indoor agritech specialist IGS has launched Clima, its new digital publication and accompanying podcast series. Through Clima, IGS will welcome industry-leading interviewees and share thought pieces on some of the most fundamental issues facing the world, including supply chains, agricultural innovation, and indoor growing.
About IGS:
Founded in 2013, IGS brought together decades of farming and engineering experience to create an agritech business with a vision to revolutionize the indoor growing market. Its commitment to innovation has continued apace and it has evolved the applications of its technology beyond agriculture to create solutions for a wide variety of indoor environments that enhance life for people, plants, and animals.
IGS launched its first vertical farming demonstration facility in August 2018, based at the James Hutton Institute in Invergowrie.

Shipping Container Farms Come to London as Growers Ditch Soil
In the era of climate change and Brexit, British farming is facing unprecedented challenges. How to supply environmentally friendly, locally sourced, and competitively priced food?
Vegetables Are Grown Vertically Supplied With Nutrient-Rich Water

In the era of climate change and Brexit, British farming is facing unprecedented challenges. How to supply environmentally friendly, locally sourced, and competitively priced food?
One part of the answer could lie in a shipping container in an east London car park, just moment’s away from the capital’s business district. Inside are racks of leafy green vegetables, grown vertically using hydroponic technology. Instead of being planted in soil, the vegetables are plugged into a system of nutrient-rich water and kept at the optimal temperature, under specially designed lighting.
The result is flavorsome lettuces, kale, basil, and other leaves, free of pesticides and using up to 95 percent less water than traditional agriculture over a fraction of the space. The shipping containers, which are custom made, mean the produce can be located virtually on the doorstep of its market, effectively eliminating food miles.“
Traditional organic farming is not sustainable if we're going to feed a population,” says Sebastian Sainsbury, the founder of Crate to Plate, which has just had its first harvest.
Not only does Crate to Plate use otherwise wasted space - these three shipping containers can grow the equivalent of an acre’s soil - but the proximity to customers keeps the produce fresh.“ When you harvest the lettuce from the soil, within 48 hours, you've lost 40 percent of the nutritional value. And it goes down every day,”
Indoor farming has boomed in recent years, particularly in the US, where Mr. Sainsbury lived until recently and where he developed his business.
But the UK is yet to fully capitalize on its opportunities, says Dr. Robert Hancock of the James Hutton Institute, which is supporting pioneering vertical farming techniques from its facility in Dundee.“
Even with current technologies and current efficiencies, there's probably a lot more that can be done. And I think that indoor farming can interface a lot more with the broader agricultural picture,” he said.

Environment Secretary George Eustice this week said vertical farming would have a vital role to play in helping British farming meet the challenges of climate change and post-Brexit food security.
“There are a lot of pressures on land use,” he told the parliamentary environment committee, highlighting “the tricky issue” of repairing biodiversity and soil health in our intensely farmed landscapes.
Mr. Hancock highlighted the UK’s strawberry industry, which relies on imports of propagated plants from the Netherlands, as one example of where indoor farming could boost British production. Britain produces just 7 percent of its fruit and 53 percent of its vegetables. But ultimately, he says, vertical farming can only ever be part of the answer and will likely be limited to salads, berries, and niche crops.
“The replacement for calorie crops I don't think is ever going to happen,” he said.
Crate to Plate is the latest of several hydroponic farming ventures started by those outside of traditional agriculture (Mr. Sainsbury is an ex-banker), many of which haven’t translated to long-term success. The key to seeing vertical farming at scale will be getting more existing farmers on board, says Mr. Hancock.“
They understand the economics of growing.
And they also understand the routes to market,” he said.
The government is hoping that the end of the EU's Common Agricultural Policy could be a chance for new blood to enter the agricultural industry, and will offer older farmers a “golden handshake” if they retire early.
Mr. Sainsbury employs three recent agricultural graduates and says the younger generation are eager to explore new technologies. He has also had interest from farmers keen to locate his shipping containers on their land.
So far, Crate to Plate’s economies of scale and niche produce puts them out of reach of the average supermarket shopper (think £10+ salads marketed to City workers). But they have hopes of moving into residential areas, amid a growing trend for urban farming. The dream, says Mr. Sainsbury, would be a vegetable farm in every urban neighborhood, manned by a dedicated farmer and producing fresh produce for everyone to buy.“
The aim is to make it as local as possible,” he said.
