Agricultural Production Regions

By the end of this lesson, students will be able to (per CED LO PSO-5.C, EKs C.1 and C.2):

• Define and distinguish subsistence from commercial agricultural practices (per EK PSO-5.C.1).
• Identify monocropping and monoculture as commercial agricultural patterns (per EK PSO-5.C.1).
• Explain how land costs determine intensive vs extensive farming via bid-rent theory (per EK PSO-5.C.2).
• Identify a contemporary country example of dominant subsistence agriculture and dominant commercial agriculture.
• Apply Skill 2.E: explain the degree to which the bid-rent model effectively explains agricultural land use in different contexts and regions.

Per CED EK PSO-5.C.1, "agricultural production regions are defined by the extent to which they reflect subsistence or commercial practices (monocropping or monoculture)." Per CED EK PSO-5.C.2, "intensive and extensive farming practices are determined in part by land costs (bid-rent theory)." This lesson covers two related ways of categorizing agricultural regions.

Subsistence vs commercial: who is the food for?

The CED's first big distinction asks who eats the food a farm produces. Subsistence agriculture produces food primarily for the farming household's own consumption; what is not eaten is bartered or sold locally. Commercial agriculture produces food primarily for sale on national or global markets, often through monocropping/monoculture systems. The two are endpoints of a spectrum — many real farms mix both.

Monocropping and monoculture

Per CED EK PSO-5.C.1, commercial agriculture often takes the form of monocropping or monoculture — growing a single crop variety over a large area for many years. The terms are nearly interchangeable: monoculture emphasizes the biological uniformity (one variety); monocropping emphasizes the temporal continuity (same crop year after year). Both produce economies of scale but reduce biodiversity and increase pest/disease vulnerability.

Bid-rent theory

Per CED EK PSO-5.C.2, bid-rent theory explains how land costs shape the intensive/extensive choice. Land users bid against each other for available land based on what they can earn. Intensive uses (high-value crops with high yields per acre) outbid extensive uses (low-value crops with low yields per acre) for expensive land near markets. The result: intensive farming clusters near cities and transportation; extensive farming sits far from markets where land is cheap. This is the basic logic of the von Thünen model (Topic 5.8 explores it in detail).

Per CED EK PSO-5.C.1. Memorize both ends of the spectrum.

Per CED EK PSO-5.C.2, bid-rent theory explains how land cost shapes the intensive/extensive choice. The theory is the foundation of the von Thünen model (Topic 5.8).

The basic logic

• Near a city or market, land is expensive (everyone wants it). Only intensive uses (high yields per acre, perishable crops, dairy, market gardening) can afford it.
• Far from a city or market, land is cheap (few competing buyers). Extensive uses (low yields per acre, durable crops, ranching, wheat) can profit from cheap land despite low per-acre output.
• The intensity gradient declines as you move outward from a market. This is what produces the von Thünen concentric rings.

Bid-rent applies to urban land use too (Topic 6.6 covers urban density and land use). Downtown commercial uses outbid residential uses for expensive central-city land; residential uses outbid agricultural uses at the urban edge; agricultural uses extend outward.

Four cases that show the subsistence/commercial spectrum and bid-rent dynamics.

Ethiopia · Predominantly Subsistence

~70% of population in rural agriculture

Ethiopia is one of the world's most subsistence-agriculture-dominated economies. Most rural households grow teff, maize, sorghum, and other staples primarily for their own consumption. Recent commercial expansion (cut flowers for European markets, coffee exports) is changing the mix, but subsistence remains dominant for the rural majority.

United States · Predominantly Commercial

~1.4% of population in agriculture

US agriculture is the textbook commercial case. About 1.4% of Americans work in agriculture, but they produce enormous food output for both domestic consumption and global export. Monocropping (Iowa corn-soybean rotation) and monoculture (cotton in the South, almonds in California) dominate. The bid-rent model is visible: dairying near urban centers, grain in the open country.

Brazil · Both Coexist

~$200B agribusiness; many subsistence smallholders

Brazil shows commercial and subsistence agriculture coexisting at large scale. Industrial soy, beef, sugarcane, and coffee plantations dominate the productive cerrado and former Atlantic forest. Yet millions of small subsistence farmers continue to work in the Northeast and the Amazon. Brazilian agriculture is one of the most socially polarized in the world.

Netherlands · Bid-Rent Extreme

~$100B agricultural exports despite small land area

The Netherlands is the bid-rent textbook case at extreme intensity. Dutch land is some of the most expensive farmland in the world; the response has been hyper-intensive horticulture (greenhouse vegetables, flowers, dairy). Despite tiny area, the Netherlands is the world's second-largest agricultural exporter by value. When land cost is high, intensification is the only viable strategy — bid-rent theory in pure form.

1. Per EK PSO-5.C.1, agricultural production regions sit on a subsistence-commercial spectrum. Pick one country that has shifted significantly from one end to the other in recent decades. What drove the shift?
2. Monocropping and monoculture produce economies of scale but reduce biodiversity and increase pest vulnerability. What policy interventions could capture the productivity gains while reducing the risks?
3. Bid-rent theory predicts that intensive farming clusters near cities. Suburban sprawl pushes farmland outward and converts it to housing. What does this mean for urban food systems? Are local food movements (Topic 5.11) a response to this geographic pressure?
4. The Netherlands produces ~$100B in agricultural exports despite tiny land area; sub-Saharan African countries with vast land area produce far less in commercial exports. Bid-rent theory and intensive farming explain part of this. What other factors matter?
5. Subsistence agriculture supports food security at the household level but not the national or export level. Commercial agriculture produces national wealth but can leave farming households dependent on commodity prices. Which is "better" for a developing country to prioritize? Defend your answer.
