The IAASTD describes this development model of industrialized nations as the “agricultural treadmill”. "The Agricultural treadmill: (...) Farmers who adopt early use of a technology that is more productive or less costly than the prevailing state-of-the-art technology, i.e., when prices have not as yet decreased as a result of increased efficiency, capture a windfall profit. When others begin to use the new technology, total production increases and prices start to fall. Farmers who have not yet adopted the technology or practice experience a price squeeze: their incomes decrease even if they work as hard as before." (Global, p. 73)It is based on technological advances achieved through mechanization, plant breeding for high-yielding varieties, the use of agrochemicals and genetic engineering, etc. With increasing external inputs, the unit costs of production are declining and the productivity per worker is increasing. Production is growing and producer prices are falling. The only businesses that can survive on the market are those that remain one step ahead of their competitors by investing in rationalization and expansion, or those with locational advantages. If others catch up with them, another round begins. An end to this treadmill is not in sight: The more global the market, the higher the speed and the more incalculable the game becomes for each participant.
