Four emerging technologies --AI, robotics, advanced energy systems and sensor networks -- are poised to reshape global labour markets with the greatest impact expected in seven core sectors employing 80 per cent of workers worldwide, a study said on Tuesday.

These technologies will create new opportunities to boost productivity and transform jobs in agriculture, manufacturing, construction, wholesale and retail trade, transport and logistics, business and management, and healthcare sectors, the World Economic Forum said in its 'Jobs of Tomorrow: Technology and the Future of the World's Largest Workforces' report.

Unlocking this productivity potential and managing risks will require concerted actions such as mobilising investment capital, accelerating global technology diffusion and ensuring inclusive access, the WEF said.

"The path of technology development will be determined by decisions made now and in the coming years," said Till Leopold, Head of Work, Wages, and Job Creation, WEF.

"Understanding which technologies will be most transformative and how they will transform seven job families that make up almost 80 per cent of the world's workers is crucial to anticipating their impact and driving towards positive outcomes," Leopold said.

While the global debate has focused on desk-based office jobs, the report highlighted how emerging technologies are also driving real-world change beyond such occupations. Drone technology is already enabling efficient urban deliveries in the United Arab Emirates and for transporting critical supplies - such as medical equipment - to rural Ghana.
