  • Self-fertilizing crops are one of the world’s Top 10 Emerging Technologies, according to the World Economic Forum and Scientific American.
  • Other technology trends include developments in low-carbon shipping and 3D-printed homes.
  • Expect more buzz around the metaverse in 2022 with lines between the physical and digital worlds continuing to blur.


Metaverse is one of the hottest buzzwords of the moment. It’s basically a virtual world created by combining different technologies, including virtual and augmented reality.

While it doesn’t technically exist yet, companies like Facebook hope the metaverse will become a place where we go to meet, work, play, study and shop.

This ‘extended reality’ is predicted to be the next evolution of the internet and will blur the lines between physical and digital life. Think in-game purchases, where computer gamers can buy virtual goods and services using real money. Jobs in the metaverse might include personalised avatar creator or metaverse research scientist.

Self-fertilizing crops

Fertilizer containing around 110 million tonnes of nitrogen is used in global crop production every year. This accounts for 1% to 2% of global carbon dioxide (CO2) emissions.

But plants like soy and beans – from the legume family that also includes peas and lentils – use a “clever way” to produce their own nitrogen – according to the Top 10 Emerging Technologies of 2021 report, created by popular science magazine Scientific American and the World Economic Forum.

Scientists now hope to “coax” other crops like corn and other cereals to self-fertilize.

3D-printed houses

Feeding materials like concrete, sand and plastics into a massive 3D printer to print homes is a “relatively simple and low-cost construction method,” the Forum says in the report.

But lack of infrastructure to transport materials has precluded the use of 3D printing for the remote and emerging regions where it could have the most impact.

This could change if more companies follow the lead of Italian 3D printing company WASP, which has demonstrated how to print housing components using local materials like clay soil.

Low-carbon shipping

Today, 2% or less of road transport fleets produce zero emissions. But, as a result of bulk shipping - both rail and seaborne - low-carbon solutions have emerged, says Bernard S. Meyerson, Chief Innovation Officer Emeritus at IBM and Vice-Chair of the Top 10 Emerging Technologies steering group.

These include a CO2-emission-free passenger train, the Coradia iLint, and the development of alternative shipping fuels like green ammonia, a carbon-free gas produced using renewable energy.


What is the World Economic Forum doing to improve digital intelligence in children?

The challenge is getting these technologies applied at scale, Meyerson says in the Top 10 Emerging Technologies of 2021 report.

“The barriers are not just technological but also political, given that such transformational programmes require significant capital investment,” he adds.

Could 2022 bring advances here? French rail transport manufacturer Alstom says its Coradia iLint is the world's first hydrogen fuel-cell passenger train.



Cryptocurrency is moving from the “fringes of finance to the mainstream”, according to Thomson Reuters Foundation, the global news and information services company.

El Salvador in Central America became the first country to make bitcoin – the original and most popular cryptocurrency – legal tender in September 2021.

Meanwhile, central banks in Sweden, Canada, the European Union and the United Kingdom are among those considering their own digital currencies.

Not all, however, are embracing this development in the future of finance. Concerns about potential risk and fraud have seen countries including China, Bangladesh, Qatar, Egypt and Morocco ban cryptocurrency.

Using vastly powerful computer systems to ‘mine’ for new crypto is also bad for the environment. But there are tech industry experts who believe that, with regulation, it will become a more sustainable legal tender of the future.
