Introduction to Agriculture

By the end of this lesson, students will be able to (per CED LO PSO-5.A):

• Explain the connection between physical geography (climate and environment) and agricultural practices, with specific reference to Mediterranean and tropical climates (per EK PSO-5.A.1).
• Identify and define the three CED-named intensive farming practices: market gardening, plantation agriculture, and mixed crop/livestock systems (per EK PSO-5.A.2).
• Identify and define the three CED-named extensive farming practices: shifting cultivation, nomadic herding, and ranching (per EK PSO-5.A.3).
• Distinguish intensive from extensive farming based on labor/capital intensity per unit of land.
• Apply Skill 2.D: explain the geographic significance of agricultural similarities and differences across climate zones and regions.

Per CED EK PSO-5.A.1, "agricultural practices are influenced by the physical environment and climatic conditions, such as the Mediterranean climate and tropical climates." Per EKs A.2 and A.3, the CED names exactly six farming practices — three intensive and three extensive — that frame Unit 5's analysis of agricultural geography.

Climate constrains the menu

Climate sets the basic parameters of what can grow where. Tropical climates (consistently warm, abundant rainfall) favor rice, bananas, sugarcane, and cocoa. Mediterranean climates (hot dry summers, mild wet winters) favor olives, grapes, citrus, and wheat. Temperate climates support corn, soybeans, dairy, and a wide range of crops. Arid and semi-arid regions support grazing more easily than crop cultivation. The CED specifically names Mediterranean and tropical climates because they show the strongest crop-climate alignment.

Intensive vs extensive: the central distinction

The most important conceptual move in Topic 5.1 is the intensive/extensive split. Both terms describe the ratio of labor and capital to land:

• Intensive farming uses a lot of labor or capital per unit of land. Yields per acre are high. Used where land is expensive or scarce. Includes rice paddies, orchards, market gardens, plantations.
• Extensive farming uses a lot of land per unit of labor or capital. Yields per acre are low, but yields per worker can be high (with mechanization) or moderate (with traditional methods). Used where land is cheap or where physical conditions limit intensive use.

Why these six practices specifically

The CED names exactly six practices in EKs PSO-5.A.2 and PSO-5.A.3. They were chosen because they cover the major patterns in world agriculture and because each is geographically distinctive. Memorize all six names and one country example for each. They appear repeatedly across Unit 5 and on the AP exam.

Per CED EK PSO-5.A.1, the CED names two climate types specifically. Both have distinctive crop signatures.

The fundamental distinction. Both produce food but use very different geographic strategies.

Per CED EKs PSO-5.A.2 and PSO-5.A.3. Memorize all six and one country example each.

Three Intensive Practices (per EK PSO-5.A.2)

Three Extensive Practices (per EK PSO-5.A.3)

Four cases that show climate-agriculture connections and intensive/extensive practices.

Italy · Mediterranean Climate Match

~12% of EU olive oil production

Italy is the textbook Mediterranean-climate agriculture case. Olive trees, grapes, citrus, and wheat all grow well in the hot dry summers and mild wet winters. The classic Mediterranean diet (olive oil, grain, fruit, fish) is the cuisine that the Italian climate produces. Greece, Spain, southern France, coastal North Africa, California, and central Chile all show similar crop signatures.

Costa Rica · Plantation Agriculture

~$1.4B annual banana exports

Costa Rica's tropical climate supports textbook plantation agriculture. Bananas, coffee, pineapples, and palm oil dominate export production. Major US fruit corporations (Chiquita, Dole) operate large plantations. Plantation agriculture is intensive (high labor and capital per acre) but historically tied to colonial exploitation and labor concerns.

Mongolia · Nomadic Herding

~25% of population still herds traditionally

Mongolia is one of the few countries where nomadic herding remains a major livelihood for a significant portion of the population. Herders move sheep, goats, cattle, horses, and camels seasonally across the steppe. The traditional ger (yurt) housing is portable; livestock is the main source of food, clothing, and trade goods. Climate change and modernization pressure threaten the practice.

Argentina · Ranching

Pampas: ~50M cattle

The Argentine Pampas is one of the world's classic ranching regions. The fertile temperate grasslands support extensive cattle ranching at industrial scale. Argentine beef is a major export and a national cultural identifier (asado, gaucho culture). Compare to the US Great Plains and the Australian Outback — the same extensive ranching pattern in different temperate grasslands.

1. The CED names exactly two climate types in EK PSO-5.A.1: Mediterranean and tropical. Why these two? What other climate types (temperate, arid, polar, subarctic) shape agriculture, and why doesn't the CED name them?
2. Distinguish intensive from extensive farming. The same crop (corn) is grown intensively in the US Midwest and extensively in some other regions. What variables determine which approach is used?
3. Plantation agriculture is listed as an intensive practice. Historically it was associated with colonialism, slavery, and labor exploitation; today it is often corporate. What are the contemporary debates about plantation agriculture (palm oil, bananas, sugar)?
4. Nomadic herding is one of the oldest agricultural practices but is rapidly declining (climate change, government settlement policies, fencing of grazing land). Should nomadic herding be preserved? If so, by whom and how?
5. Connect Topic 5.1 to Topic 1.5 (Human-Environmental Interaction). How does the climate-agriculture connection illustrate possibilism rather than environmental determinism?
