The Agri-food chain
Farming
Processing & Distribution
Breeding
• Power-intensive tasks.
• Control-intensive tasks.(Binswanger, 1986).

20th Century Mechanization: Power-intensive tasks
• USA average labor/acre to produce corn for grain:
1915-19: 34.2 hrs
1974-78: 3.7 hrs
2015-17: 2.7 hrs.
![Page 11: Smart automation in the agri-food chain: State of the art ... · Smart automation in the agri-food chain: State of the art, prospects and impacts on workforce demands Stavros G.

Present: Precision Agriculture (PA) - Variable Rate (VAR) technologies
• Utilize technology to apply:
– The right types and exact amounts of inputs;
– At exactly the right time and place.
• Power and control intensive: high throughput and selective.
• PA technologies:
– Affect mainly the efficiencies of inputs (water, chemicals, seeds, energy).
– Maintain demand for manual labor.
– Increase demand for technology-related skills.

Present-Future: Robotics-Mechatronics-Automation
• Advances in robotic/mechatronic technologies:
– Computers, electronics, sensors, actuators, perception.
• Incorporated into agricultural machines in two different ways:
I. Increased automation on existing (large) machines.
II. Smart robotic implements & self-propelled, autonomous (smaller) robots.

Present-Future: Smart Automation – Smart Farming
• Manage processes in the agri-food chain via collective use of hardware and software to:
– Collect data;
– Extract and process information from data;
– Contribute to decision-making;
– Take physical actions.
• Our focus today: on-farm, labor-impacting smart automation.
– Applicability also on post-harvest.
![Page 14: Smart automation in the agri-food chain: State of the art ... · Smart automation in the agri-food chain: State of the art, prospects and impacts on workforce demands Stavros G. Vougioukas1](https://reader034.fdocuments.in/reader034/viewer/2022050522/5fa57ddabdb0191a473e3269/html5/thumbnails/14.jpg)
What are the most labor-impacting technologies?
• Farm employment in USA:
– 18% agricultural equipment operators.
– 56% farm workers (contract labor not included).
– 4% on-farm grading, sorting and packing.
• Labor-impacting technologies:
I. Full machine autonomy (fewer operators required).
II. Physical interaction with the crop and its environment in ways that were not possible before (less manual labor required).

Full autonomy for agricultural machines
II. Autonomous operation requires an operator’s advanced:
– Perception, situation awareness, judgment & task-specific knowledge.
– Not feasible soon; remote supervised autonomy is a practical scenario.
– Legal framework is not developed yet.

Smart automation and workforce
I. Remotely supervised teams of semi-autonomous machines
– Slightly less than one operator per machine needed.
– Increased demand for operator technical and application-related expertise.
• Configure, supervise, adjust and optimize the operating parameters of the automated equipment.
– Increased stress, responsibility...

Smart automation and workforce
II. Targeted physical interaction with crops & environment
– Machines automate tasks, not jobs.
– Reduced demand for unskilled labor in tasks like manual weeding and harvesting (10%-85%).
– Increased demand for machine operators with advanced skills in automation and information technologies.
– Business model turning to service?

Development of smart automation
• Large ag. equipment manufacturers lead the development of type-I automation technologies for farm machines.
• Smaller start-up companies lead innovation in robotic implements and agricultural robots that interact with crops (type-II automation).
• Obstacles for type-II automation:
– Sensing & actuation challenges are difficult and time-consuming to overcome.
– Market fragmentation: Custom-designed machine needed for each crop.
– Capacity to conduct innovative R&D locally; not available in developing world.
– It may take a while until many local crops in Africa and Asia are mechanized.

Adoption of smart automation
• The adoption of smart automation and PA/VAR technologies is still slow.
• High investment costs remain one of the most significant barriers, especially for small farms.
• A possible future is teams of smaller highly-automated agricultural machines (no operator needed on board).
• Next: European perspective on smart farming.

Not an easy task for the farming community…
81% of the Danish and 78% of the US famers preferred to store the data themselves.
88% of the US famers preferred not to store the data in a shared Internet-based database explaining the reluctance of software vendors to push in this direction, which further emphasize the importance of farm data ownership.
