- In 2018, only 3% of fruit and vegetables are eaten in the UK were grown domestically in allotments or gardens.
- With more and more people also moving into cities, urban horticulture can offer an opportunity to improve access to healthy foods and reduce inequalities.
- Technological advancements such as soil-free growing, like hydroponics systems, can also allow farming on rooftops or in disused buildings without natural light.
The recent target of a 30% increase in fruit and vegetable consumption in the UK by 2032, set last year by the independent National Food Strategy review, means we need to consider how these fruit and veg can be grown sustainably: and how we can encourage people to eat more of them.
Urban horticulture is a largely overlooked way of providing fresh, high-quality food to city dwellers by producing fruit and vegetables within cities, that has historically been vital for the UK’s food supply.
During the second world war, as part of the government’s “Dig for Victory” gardening campaign, 18% of the fruit and vegetables eaten by UK citizens were grown domestically in allotments and gardens. Yet in 2018, that figure was just 3%.
With 84% of the UK population now living in cities and towns, as a nation we’ve become largely detached from the practice or possibility of growing our own food. But there’s more and more evidence to suggest that reviving this practice could be the key to shoring up our food security against threats like climate change, supply chain breakdowns and disease.
Five a day
Just over a quarter of the UK population actually eat “five a day”: the number of portions of fruit and vegetables the World Health Organization recommends adults consume. This is linked to income: the richest 20% of the population eats on average one portion more of vegetables per day compared to the poorest 20%. And the consequences are serious: a diet lacking in fresh fruit and veg can increase the risk of stroke, heart disease and some cancers.
If we are to address these inequalities, we need to create an equal food environment. Promoting urban horticulture could help achieve this by putting fruit and vegetable production back at the heart and in the hands of local communities.
Commercially grown fruit and vegetable crops in the UK provide just over half of the vegetables and under 20% of the fruit we eat from a very small area of land – equivalent to 23m² per person.
Recent research carried out in Sheffield found that there was the equivalent of approximately 97m² per person in the city that could potentially be used for growing fruit and vegetables. That’s enough land to feed over 120% of the Sheffield population following a five-a-day diet.
Not all of this land should or could be used for growing food. The pandemic has demonstrated the numerous benefits to health and wellbeing of providing people with green spaces. But if just 10% of this available land was used for growing fruit and vegetables, when combined with existing allotments in Sheffield, there would be enough growing space to feed 15% of the population five portions of fruit and veg a day. This would be a big increase on the estimated 3% of Sheffield’s population currently fed on five a day from urban allotments.
What’s more, growing food in cities doesn’t have to be confined to green spaces. Technological advancements in soil-free growing, such as hydroponics systems, allow people to grow produce on rooftops in cities or in disused buildings without natural light.

Shifting fruit and vegetable production into cities also offers a cultural challenge around how to encourage more urban dwellers to grow their own food: which means understanding the barriers that put people off.
At Sheffield’s Institute for Sustainable Food, we’re calling on the government to do more to engage urban communities with growing through funding community and school gardens, allotments and hyperlocal farms focused on very specific areas. This could result in a patchwork of food growing regions across cities that, in time, become an integral part of the UK food system.
What is the World Economic Forum doing to help ensure global food security?
Two billion people in the world currently suffer from malnutrition and according to some estimates, we need 60% more food to feed the global population by 2050. Yet the agricultural sector is ill-equipped to meet this demand: 700 million of its workers currently live in poverty, and it is already responsible for 70% of the world’s water consumption and 30% of global greenhouse gas emissions.
New technologies could help our food systems become more sustainable and efficient, but unfortunately the agricultural sector has fallen behind other sectors in terms of technology adoption.
Launched in 2018, the Forum’s Innovation with a Purpose Platform is a large-scale partnership that facilitates the adoption of new technologies and other innovations to transform the way we produce, distribute and consume our food.
With research, increasing investments in new agriculture technologies and the integration of local and regional initiatives aimed at enhancing food security, the platform is working with over 50 partner institutions and 1,000 leaders around the world to leverage emerging technologies to make our food systems more sustainable, inclusive and efficient.
If this comes to fruition, we can expect to see health and wellbeing benefits across the board – not just thanks to more nutritious diets, but also because of the dramatic improvements in wellbeing that belonging to an active community can bring.
