Future of food: how and what will we eat in 2050?

A summit held by the UK Pavilion at Expo 2020 Dubai revealed veganism is not the solution to the food crisis.

Sobering food documentaries such as Netflix’s Rotten point to an Armageddon of our global food supply, crippled by climate change, crime and corruption. But academics, entrepreneurs and policymakers from the agritech and food sectors, who attended In the Future, What will we Eat, an online food summit hosted by the UK Pavilion at Expo 2020 Dubai on Thursday, made room for optimism.


Our “farm-to-fork menus” can look the same in 2050, they said, if we’re willing to adapt our consumer behaviour.


One meaty paradox lay at the heart of discussions: how do we feed the world without destroying the planet?

The problem of food waste

The global food sector is under pressure to produce more in the next 50 years than it did in the past 500, to nourish a projected global population of 11 billion by 2050.


Perhaps the most unpalatable injustice highlighted by the summit was that more than twice the amount of food is being produced to feed the entire world’s population, while 870 million people go hungry, pointing to the crux of the sustainability issue: food waste.

A United Nations report stated that 931 million tonnes of food was wasted in 2019 at the consumer level, that is waste attributed to individual households.

The solutions

An obvious solution is that, when it comes to waste reduction, we, as laypeople, are huge players. “Saving waste is a trillion-dollar opportunity,” said Ignacio Ramirez, operations manager at Winnow Solutions Mena.



“Every dollar saved on waste equates to fourteen dollars saved on investment. Becoming more sustainable does not cost more, it’s simply better for everyone.”


Mining data


All 25 speakers at the UK Pavilion summit agreed the future of sustainable food production will rely largely on data collection and in translating that information to empower those on the ground. John McElhone, co-founder of agritech company CropSafe, said that a mere 1 per cent increase in food production by the 500 million farms globally would feed millions more.


“We’ve gone from horse-drawn carts to self-driven tractors in 100 years. Technology means farmers don’t need to walk the land to identify issues. That information can be collected in less than one second using satellites, probes, drones and digital cameras.”

And empowered by intelligent data analysis, farmers of the future will become “green magicians”, said Dr Stephen Christie, chairman and chief executive of data science and machine learning company Agxio.


Yet another agritech start-up is replacing big tractors with small robots. Ben Scott-Robinson of the Small Robot Company said that two crops produce 70 per cent of what we eat: wheat and maize. “Most UK farms aren’t profitable today without subsidies. Yields have flatlined as [mechanised] systems are inefficient.”





A change-maker in Dubai is the non-profit agricultural research centre ICBA, where drones and research have been used since 1999 to solve the problem of soil and water salinity in harsh environments across the Middle East and North Africa. Research since 2022 on the humble date palm has shown that crop yield and taste can be improved using saline water irrigation.


Visitors to Expo 2020 Dubai can see this process in action at The Desert Farm where “smart” plants such as Salicornia (sea beans) and quinoa are shown to thrive on saltwater, and scientists work on turning deserts into farmland for grazing animals and to curb deforestation.


A partner of Madar Farms in Abu Dhabi, IGS, or Intelligent Growth Solutions, has been identified by The Economist as one of the 15 innovative technologies that will save the planet. Producing energy-efficient, zero-emission vertical farms, chief executive David Farquhar said one IGS tower is 1,000 times more efficient at producing crops than one field.



“Our indoor towers require no humans, no hydrocarbons, produce no emissions and result in massive water savings.”


The panel also identified seaweed as an alternative fast-growing “wonder crop” as it improves biodiversity and absorbs C02 more quickly than trees.


Phones to the rescue


Seasonality and locality will define a more sustainable approach across hospitality and retail sectors, said Ibrahim Al-Zubi, chief sustainability officer of Dubai-based Majid Al Futtaim Holdings, which operates Carrefour stores in 37 countries. And, he said, as 60 per cent of the UAE’s population is under the age 30, smartphones are the key to progress.

As an example, the food and drink app Too Good to Go, was co-founded by Jamie Crummie with the vision of creating a zero-waste planet. Connecting customers with restaurants and stores to rescue “surprise bags” of fresh, unsold food, the app is working closely with retailers Starbucks and Costa Coffee, as well as 120,000 businesses and 50 million consumers globally, to drive policy solutions that will inspire behavioural change.


While myriad data-driven solutions were outlined during the four-hour panel, there was one surprising omission.


Veganism is not the solution to the world’s food crisis,” said Chris Elliott, professor of food safety and founder of the Institute for Global Food Security at Queen’s University Belfast.


“There are more ex-vegans than vegans on the planet, because many tried it and didn’t like it. The answer does not lie in plant-based versus animal foods, but rather in alternative environmentally friendly options, innovation, improved soil fertility and better transparency.”
