Economic analysis of Hands Free Hectare set to be presented

Posted 8 April

"Robotics will radically change the economies of scale in arable farming"

The Hands Free Hectare

An economic analysis based on the Hand Free Hectare (HFHa) experience provides the first concrete evidence that crop robots will help make UK farmers more competitive and improve environmental management.

This is the core message of a paper to be presented to the Agricultural Economics Society (AES) Annual Conference April 15-17 in Warwick by Professor Karl Behrendt, who holds the Elizabeth Creak Chair in Agri-Tech Economic Modeling at Harper Adams University.

“Robotics will radically change the economies of scale in arable farming,” Behrendt said. “Once human drivers are removed from farm equipment, the motivation for large farm machines almost disappears. Evidence shows that swarms of smaller farm machines can be cost-effective on modest size farms, even when fields are small and irregularly shaped.”

The lead author of the AES paper is Professor James Lowenberg-DeBoer, with other co-authors Professor Richard Godwin and Kit Franklin (leader of the Hands Free Hectare project), all from Harper Adams University. Many robotics researchers and entrepreneurs have argued that robots would be both profitable and good for the environment, but this is the first whole farm economic analysis supporting that argument. The research was based on experience with the Hand Free Hectare at Harper Adams University in 2017 and 2018 producing grain entirely with small scale farm equipment retrofitted for autonomous operation.

“Swarm robotics will help small and medium sized British farms compete after BREXIT,” Behrendt said. “For example, this analysis shows that with robotics the cost of wheat production in the UK can be competitive with countries that now export wheat to Britain. With robotics, the economic forces driving hedge removal, cutting field trees and other changes to the British landscape will be mitigated.”
