Agricultural practices focused on producing crops and livestock for sale off the farm are a defining characteristic of modern food systems. This type of farming prioritizes maximizing yield and profit through specialized techniques, large-scale operations, and integration into global markets. An example includes a vast wheat farm in the Great Plains, where the entire operation is geared towards selling the harvested grain to processors and distributors.
The emphasis on efficiency inherent in this system has led to significant advancements in agricultural technology and productivity. This allows for increased food production to meet the demands of growing populations and has stimulated economic growth in many regions. Historically, the shift from subsistence to this form of agriculture has been a key component of economic development, facilitating urbanization and industrialization by freeing up labor and providing food surpluses.
