When the cost of producing good items decreases as the quantity of production increases. It shows large scale farming is more efficient, and that average production costs decrease as farm size increases.

areas where residents lack healthy nutritious foods due to distance, live more than a mile away, occurs in almost every city

Reservoir

artificial lakes by dams or across streams or rivers, reservoirs

Terracing

causing parts of hills or mountains into small level growing pots, mountains and tropical wet climates, "steps", water goes down but not soil, results in healthy crops but labor intensive, cultural heritage that everybody helps, example: ifugao rice terraces in philippines

Vertical Integration

Bid-Rent Theory

explains how land value determines how a farmer will use the land - either intensively or extensively, where land value is high farmers will buy less land and use it intensely to produce the most agricultural yield per unit of land, when land has a lower value or is farther from the market, farmers will buy more land and use it less intensively or extensively.
