Intensive and Extensive Farming Practices

Every farming system trades off three things: land, labor, and capital. Intensive farming squeezes high yields out of small plots by pouring in labor, money, machinery, fertilizer, or irrigation. Extensive farming does the opposite: it spreads minimal labor and capital over huge stretches of land, letting the land itself do more of the work. Neither is better in some absolute sense. Each is a rational response to the land available, the climate, and how close a farmer sits to a market willing to pay for the crop.

Market gardening, plantation agriculture, and mixed crop-livestock farming are all intensive. Market gardening grows fruits and vegetables on small plots near cities, with careful tending because the crops are perishable and buyers are close. Plantation agriculture pours labor and capital into cash crops like bananas, sugar, or coffee, often in the tropics, for export rather than local eating. Mixed crop-livestock farming rotates crops and animals on the same land to keep soil fertile and labor employed year round. Extensive systems look different: shifting cultivation clears a plot in tropical forest, farms it a few years, then moves on once soil nutrients run out. Nomadic herding and ranching use dry or semi-arid land where vegetation is too sparse to farm intensively, so people move animals across wide ranges instead.

This topic sets up Von Thunen's model, which explains intensive and extensive land use as rings around a central market, with intensity falling as distance and transport cost rise. It also connects to the Green Revolution, which pushed many farms toward intensive methods by boosting yields per hectare through new seeds, fertilizer, and irrigation.
