Planting our own future: How vertical and urban farming is helping to fix our food supply chain

A survey published by The Food Foundation in April 2022 revealed that food insecurity is indefinitely on the rise within UK households as the July 2021 figure has risen from 7.3% to 8.8%. With Covid-19 and Brexit causing our food supply chains to be compromised, traditional farming failing to meet demand and food costs continuing to soar. A change is essential and evidence is showing a sustainable food system may be the solution.

 

 

 

 

There is a glimmer of hope for our fragile food supply chain hidden behind an office door. That may seem difficult to believe but it is entirely true.

Chris Fisher found his Manchester based start-up company, Red Planet Farms, in January 2021 and through determination, passion and a belief that vertical farming is the way forward for a sustainable food chain, the Canadian-born scientific engineer turned his tiny office space into a green paradise.

 

“We are the first vertical farm start-up in the North West which is brilliant, we're coming in right now

growing sustainable, local food with zero pesticides and it is all just air, water and light. That’s the magic recipe.” Chris said.

 

Vertical farming is a practice which involves growing small crops other known as ‘microgreens’ in an indoor, LED lit environment with water and temperature levels being carefully regulated. By personally monitoring the crops’ development, this farming revolution is helping to rapidly grow in-demand vegetables and shorten the miles between farm-to-fork.

 

Chris said: “So what we're trying to do here is grow food for cities inside the cities and be able to offer customers a more sustainable solution.

 

“The food poverty experience here in the UK is crazy to see. There definitely has to be more initiative in urban farming. There's a lot of problems out there and vertical farming is part of the solution.”

​

By watching Clarkson’s Farm on Amazon Prime, Chris was able to see the reality of what farmers deal with day-to-day and how the weather and natural environment can wreak havoc on crops natural growing processes.

 

Chris continued: “And then we look at climate change and how that's affecting everything. Along with Brexit and Covid-19 and how they've affected supply chains but in a seven day 7 to 14 day window you can go from seed to harvest.

 

“We have a whole bank of seeds, different varieties this morning were planted so we have some coriander, pea shoots and garlic chives growing away. So they start their life on the soil medium and we give them lots of water and darkness to help them break out of their seeds so they can start to grow."

Another desire that Chris has is to revolutionise agriculture for possible 'off-world colonies.' He had no prior expertise cultivating crops or plants of any kind on a large scale before starting Red Planet Farms. However that changed when his fascination for space educated him about the potential of vertical farming in his bedroom.

 

“I really believe in colonisation and exploring the solar system and beyond,” he said. "So one of those things is, you know, how are people going to sleep up there? How are they gonna drink up there? How are they going to breathe and one of the big questions is how are they going to eat?

 

"So I said look, I'm going to tackle that one, and we really want to be the pioneers of that."

 

But, for the time being, Chris and Red Planet Farms believe that the only way is up and intend to concentrate on addressing food poverty caused by our fragile supply chain by supplying fresh produce in a controlled environment.

Being stuck at home for the duration of the Covid pandemic highlighted just how limited our access to food is. With supermarket shelves empty and waiting lists for food banks increasing, many turned to growing their own fruits and vegetables, whether it was on rooftops, windowsills, or allotments; urban gardening became a lifeline for many.

 

According to research by Professor Dave Goulson from the University of Sussex, per hectare allotments can produce up to 35 tonnes of food and with the most recent figures stating that more than 100,000 people in the UK being on allotment waiting lists, those who have been approved can choose to make a difference for the sake of our planet.

 

In the summer of 2019, the Howarth family applied for their allotment after recognising the damage Brexit had proposed to our country’s food production. However, they were not expecting their application to be approved just before lockdown began in 2020. Despite a fresh crop of challenges being thrown their way, the family allotmenteers put on their wellies, grabbed their trowels and got stuck in.

Looking back on the start of their journey, Dan, 37,  turned to his wife Jen saying:

 

“You've consistently killed every houseplant by the half, it wasn't very successful, but we grew a few tomatoes.” 

 

Jen added: “There was a big Jamie Oliver article about chlorinated chicken and things like that, so that was a big driver behind it and we said right, we're applying for an allotment but we didn't have much experience. It has been a bit of a baptism of fire, but it's been fun, hasn't it?”

 

With lockdown causing Jen, who runs children’s sensory classes, to be furloughed and with schools being closed, the Howarth's had a lot of time and energy to put into their allotment. This helped them to focus on creating a safe haven for their six-year-old daughter Elsie, who has ended up thriving in the outdoor environment.

 

“I think the best thing to come out of this is to have a project we can all work on, we have separate careers but to get to come here and do stuff as a family it’s such a nice feeling. We put a lot of work into it consistently and to be able to come down here and see something we’ve achieved and you know, touch it, eat it, it’s amazing.” Jen said.

Dan and Jen were also welcomed by the other allotmenteers including John, a generous gentleman who provided a greenhouse and taught Elsie the importance of bees. 

 

 Jen said: “Throughout lockdown me and Elsie spent pretty much every day here it was great, she was three at the time so this is what she’s known for the past three years. She now goes into school telling all the teachers about composting and all sorts. Even when John had the other lot she would go over and he would teach her how to stroke bees and learn about flowers." 

 

“I think lockdown unlocked a lot of people. I would definitely encourage people to get an allotment if they can. but you’ve got to be prepared for it, it is an awful a lot of work.”

In terms of their future plans, the Howarth’s are hoping to donate their surplus crops to community centres and  inspire fellow city dwellers to start their own urban gardens.

 

Dan said: "I think it’s about educating people to eat more seasonally, you don’t need a massive space to grow some tomatoes, lettuce and fresh produce. You don’t need to buy seeds every year, if you save them correctly you will have an everlasting supply.”

Robots VS worms: welcome to the fourth agricultural revolution 

GIF-2.gif

Tom, Dick, and Harry are three hardworking farmers who are assisting in the transformation of the food agricultural sector, which is in desperate need of change. With yields beginning to stagnate, costs rising by nearly 8% per year, and land being harmed by an unpredictable climate, these hard workers are maximising food production and ensuring farming's long-term viability.

 

Oh, did we mention they are robots?

Small Robot Company is a UK AI and robotic farming startup working to create a data-driven revolution that will ensure the agricultural industry's safety in the future. The company was established by Ben Scott-Robinson, a technology assistant, and Sam Watson Jones, a farmer. Sarra Mander, the company’s chief marketing officer told us about their background and said:

 

“From Sam's perspective he was a farmer for seven years on his father’s farm, when he was looking at the prime accounts, he was really quite shocked at what he saw, his conclusion was either his father was a terrible farmer or there’s something very wrong with farming either in the UK or globally, and so he asked around other farmers and they said ‘you’re absolutely right’.

 

“What he was looking at was that the costs of seeds, fertilisers, machinery were rising and Sam discovered that around 85% of UK farms are not profitable without subsidies, His conclusion was at some point in the future sooner or later, his farm would go out of business.”

 

Sam began to look for answers after being shocked by this and came across Professor Simon Blackmore, the head of precision farming at Harper Adams, the UK's leading provider of higher education for the agricultural and rural sectors.

After approaching several machinery manufacturers with his ideas, Professor Blackmore was turned away and labelled "crazy" for wanting to build robots when tractors were arguably still profitable within the industry. However, both Sam and Ben, who were individually exploring robotics and geospatial technology believed in Professor Blackmore and came together to form the creation of The Small Robot Company.

​

British agriculture produces 64% of all food consumed in the UK and it is estimated that 7.2 percent of all food harvested is lost before it leaves UK farms each year.

​

So could AI farming be the way forward?

 

Robotic farming has a lot of potential, and 140 UK farmers are already on the waiting list for these three prototype robots, which will collect 'per plant' data and help to develop a complete picture of crop health, reducing waste and ensuring the best yield possible.

Meet Dick, the prototype weeding robot. By using per plant intelligence, Dick will travel around the field and place a robotic arm over any chosen weed crop, specifically Blackgrass and eliminate it using electricity. The herbicide to currently control the growth of blackgrass costs UK farmers £400 million per year and results in 800,000t of lost harvest.

Tom will firstly need to be there to detect any weeds. This has already proven effective by Tharus, a British robotics company which has taken Tom for a trial at the Lockerley Estate in Hants. Tom has already identified  250,000 weeds out of 12.7 million plants in a 6ha field.

The last robot in the equation is Harry. The precision planting robot is designed for combinable crops and will drill punch seeds, resulting in minimal soil disturbance. In the UK alone, 17% of arable land shows signs of erosion and restoring fertility by 2030 is an aim of the Government’s 25 Year Environment Plan.

This technological transition will take time but the Small Robot Company has already secured £11 million in funding from Crowdcube rounds and Government funds and are opening farmers’ minds to answer the questions surrounding biodiversity, climate change and food security, all of which could benefit from a secure and flourishing agricultural industry.

​

However, whilst these advanced robots are working hard to replenish our soil health, there’s a more natural team of workers underground who are doing the same, the humble earthworm.

 

A single tablespoon of worm manure contains more microorganisms than humans on the earth, and by effectively farming this manure, nutritionally rich fertiliser can be generated, assisting not only farmers, but communities in strengthening food production. 

 

One woman who is putting this practice into action is Anna de la Vega who launched her company ‘The Urban Worm’ in 2016 in hope to save our planet, one worm at a time. 

​

Anna believes these wriggly creatures hold a more straightforward solution to food insecurity saying:

 

“I decided to retrain and officially study human security and environmental change and saw the fragility of our soil, the impact of industrial agriculture and namely, these big tech companies that were destroying the soil, destroying the livelihoods of our farmers through pushing chemicals into the ground."

​

​

​

​

​

​

​

​

​

​

​

​

​

​

 

 

 

 

 

 

More than 40% of our topsoil has eroded and 83% of nutrients have been lost since the introduction of the synthetic fertiliser in the 1850s. With heavy chemicals being used, nitrous oxide and methane has been continuously pumped out into the atmosphere, which is 310 times stronger than carbon dioxide.

 

​But on a grassroots level, vermiculture has the power to collectively reduce these GHG emissions as by organically breaking down food waste and animal manure, the compost can be returned to our soil for future crop growth, making it a win-win for humanity and our planet.

​

Throughout her work Anna maintains a positive attitude and has already received support from farmers and UK households who are helping to #wormup the country.

 

With funds from The National Lottery Reaching Communities Fund Anna has been able to almost meet her goal of providing l000 packs of special composting Tiger Worms to households, schools and even military rehabilitation hospitals, and with 150 packs left you could be part of this eco-movement too.

 

“People need to be grounded more and remember how magnificent nature is and  how it connects us and we're not a country that has much faith but we do need something to believe in, so I worship the worms.”

The fight for legalising freeganism in the UK

F is for Freegan (Copyright- Jim Flanagan, Flickr)

You may have heard of the 2014 Paul May case where the Crown Prosecution Service called for three men to be charged with theft after they “raided” Iceland’s bins for discarded food including tomatoes, mushrooms and cheese. The freelance web designer along with two other defendants claimed that they were simply rescuing food waste that would otherwise be sent to landfill.

 

After initially being charged under the 1824 Vagrancy Act for being found in "an enclosed area, namely Iceland, for an unlawful purpose, namely stealing food" the charges were dropped after the retail chain were bombarded with criticism from fellow food waste activists.

 

This case and many others exemplify the discrepancies surrounding the legalities of the word ‘freeganism’ as Dentons Law Firm states: “Firstly, when someone discards an item, whom does it belong to? Secondly, is a freegan “dishonest” in retrieving the item, even if they believe that it morally right to do so?” 

 

Although not a freegan herself, money-saving journalist Vicky Parry believes by changing the wording within the law, this movement could hold the power to replenish access to food within UK and has started an online campaign with her company, MoneyMagpie in hope to persuade the Government to rethink their current policies and ultimately educate society about the potential freeganism has for helping food poverty.

It was after one night shift at at her old stadium bartending job when Vicky realised just how severe the food wasted was.

 

“We had something like £2000 worth of waste at the end of every shift of hot dogs,” she said. “And I was like, well, not only is that you know loads and loads of piggies that went to heaven for no reason, it was also walking home through poverty and seeing people on the streets begging.” Vicky said.

 

After approaching the stadium to request the hotdogs  be sent to a local homeless shelter, managers said that it was not possible. This is because of possession, without professional arrangements between the companies, there is a risk of being charged for underlying health risks therefore, food can not be passed onto other entities.

 

Despite understanding this, Vicky was still infuriated and believes morally, the food wasted should be provided to vulnerable people. “What happens to people who might just want to take something, not steal it?” She said, “or what happens to people who don’t have enough wages? What about homeless people who see some food?”

 

Freeganism has potential to reduce reliance on charities and to help address rising food prices, one of the many problems caused by inflation, Covid and the general economic downturn. Research shows that the CPI, which is ‘the official mechanism used to measure inflation in the UK’ showed the cost of food and drink has gone up 5.9% year-on-year as of March 2022. However, this shocking figure has not just affected luxury foods it’s also brought the prices up on staples such as rice and pasta.

Vicky said: “If the government can come up with a way to hand over responsibility of when they go to bin it, that’s all they need to do. If big businesses could stamp something and say discarded, if there was just some way of saying this is not their responsibility, that’s all. 

 

 “It’s nutritious food as well, it’s not even bad food. People are now going what’s cheaper, a pack of turkey dinosaurs or vegetables? Well it’s the vegetables, but they can’t cook.”

 

Vicky is not alone with this plea. Dr. Martin Caraher, Emeritus Professor of Food and Health Policy at the University of London, believes that the Government need to reassess their policies, not in terms of just freeganism but in terms of bringing in more alternative measures to help food insecurity, which has been heightened for low income families by Covid household debt.

 

As Universal Credit and welfare budget cuts endanger access to food even more, a system that targets health and wellbeing is needed instead of a quick solution to restore our food supply chain.

 

Professor Caraher explained “We've got is a rising obesity crisis and we've got a rising food insecurity crisis as well as a more general poverty crisis and what we've currently got is separate policies. 

 

“If we look at the roots, they are basically the same problem. It's people having not enough income to make decisions around healthy food. The whole population is getting heavier, but the largely the people who go hungry are more likely to be obese, they may go hungry part of the month and then overcompensate when they get money in another part of the month.”

​

​

​

​

​

​

​

​

​

​

Although obesity is rising, according to The Money Charity, based on February 2022 numbers, the UK’s total interest payments on personal debt over a 12-month period would have been £45bn, meaning that many low-income families are struggling to put nutritious food on the table let alone heat their homes. 

 

So what should be made a crime, people in need taking food or big retailers throwing away of millions of tonnes of perfectly edible food each year?

 

Despite zero waste being strongly advocated for, there appears to be little attention focused on freeganism, perhaps because few people have heard of it, or perhaps people are afraid of being prosecuted for theft. In any case, Vicky’s campaign has put this monumental movement on the map. Meanwhile, she is proudly voicing her views that the Government should condone the act and is steadily receiving support from the public. 

 

If her campaign is successful, Vicky will approach Parliament directly in the hope of changing this moral issue within our criminal justice system.
