Robots and AI Set to Revolutionize Farming, Experts Predict

The future of agriculture may soon feature robots and artificial intelligence (AI) working alongside traditional farming methods, according to insights from Professor Gerry Lacey of Maynooth University. His team, engaged in the Automating Regenerative Agriculture (Aura) project, is exploring innovative ways to enhance farming efficiency on a hectare of land in Co Kildare, Ireland.

The project aims to address the increasing challenge of feeding a growing global population, projected to reach 10 billion by 2050. Professor Lacey highlighted the need for a 56 percent increase in food production without expanding farmland. This must happen simultaneously with efforts to lower agricultural emissions. He noted, “We need to increase the amount of food on planet earth by 56 percent but we need to do that without using any more land.”

Agriculture faces a labor shortage, which exacerbates the issue of “field waste,” where viable crops are left unharvested. Professor Lacey explained the impact of this trend, stating, “Frequently you’ll hear farmers saying, ‘Oh, well, we couldn’t find the people to harvest this crop, so it got ploughed back in.’”

To combat this, the Aura project is developing technologies that emulate traditional harvesting methods, allowing for selective picking of ripe fruits and vegetables. Current mechanical harvesting approaches often result in uneven crop maturity, with some produce being overripe or not yet ripe. The Aura team is working on a machine designed to harvest individual fruits and vegetables at their optimal ripeness while using minimal energy.

Additionally, the project is reimagining age-old weeding techniques, employing robots that utilize boiling water to eliminate unwanted plants. Professor Lacey emphasized the importance of creating machines that farmers can maintain independently, as downtime during harvest can severely affect income.

Optimizing solar technology is another focus, with experiments on vertical solar panels that could be integrated into farmland. The Aura project collaborates with commercial partners like Irish Distillers and Comex McKinnon to enhance grain sustainability using cutting-edge technology.

The challenges faced by farmers in Ireland represent a significant engineering opportunity, according to Una Parsons, who is set to become the president of Engineers Ireland. Parsons, who has extensive experience in manufacturing and academia and operates an organic farm in Co Sligo, views the agri-tech sector as a major opportunity for the country. She noted that Ireland is well-known for its agricultural machinery and technology sectors.

Engaging young people in farming through technological advancements could help address labor shortages. Parsons remarked that young people raised on farms often become “mini engineers,” making the integration of technology appealing. She highlighted the success of Herdwatch, an AI-driven software management tool that currently supports farmers on 20,000 farms across Ireland, the US, and the UK.

Despite these advancements, Parsons believes the sector requires more support. She expressed a desire for an intergovernmental task force focused on developing the agri-tech industry and suggested that advancing agricultural technology should be a priority during Ireland’s presidency of the Council of the European Union next year.

In response to these developments, the Department of the Environment pointed to various initiatives aimed at supporting the agri-tech sector. They highlighted the VistaMilk Research Centre, which aims to transform Ireland’s dairy sector into a global leader. The department has also participated in agri-tech events connecting researchers and industry leaders from the US and Ireland.

As the intersection of robotics, AI, and agriculture continues to evolve, the potential for these technologies to reshape farming practices and enhance sustainability remains significant.
