Agribusiness and Global Supply Chains

Active tracing and role-playing make the abstract global supply chain visible and meaningful to students. When learners physically map a tomato’s journey from seed to shelf, they see geography in action and confront the real-world complexity of everyday products.

• 50 min · Pairs

Supply Chain Mapping: Follow That Food

Each pair selects a common food product (coffee, chocolate, chicken nuggets, orange juice, soybeans) and traces its supply chain from raw ingredient origin to grocery shelf. They create an annotated map showing the geographic path, identify key nodes (farms, processors, ports, distributors), and note where value is added and captured.

Analyze how a disruption in one part of the world affects food prices globally.

Facilitation Tip

For Supply Chain Mapping, ask students to use arrows of increasing thickness to show the volume of goods, not just the sequence of stops.

What to look for

Provide students with a product name (e.g., chocolate, orange juice). Ask them to list three distinct stages of its supply chain and one potential point of disruption for each stage. For example: Stage: Cocoa farming in Ghana; Disruption: Drought impacting harvest.

Think-Pair-Share: Supply Chain Disruption Analysis

Students read a short case study about a real supply chain disruption (2021 Suez Canal blockage, COVID cold-chain failures, 2023 avian flu and egg prices). They individually identify affected geographic nodes, pair to discuss ripple effects, then share with the class to build a systems map showing how disruptions propagate.

Explain who has more power in the food system: the producer, the distributor, or the consumer?

Facilitation Tip

During Think-Pair-Share, assign each pair a different disruption scenario so the whole class can later compare varied consequences.

What to look for

Pose the question: 'Who holds the most power in the global food system: the farmer growing the crop, the corporation processing and distributing it, or the consumer buying it?' Facilitate a debate where students must support their claims with specific examples from agribusiness supply chains.

Role Play: Who Gets the Money?

Students take roles in the coffee supply chain (farmer in Ethiopia, cooperative, exporter, importer, roaster, retailer, consumer) and receive cards showing each actor's share of the final retail price. Arranged spatially on a world map, they discuss whether this distribution reflects the labor and risk each actor bears.

Trace the geographic path of a common food product from its origin to your plate.

Facilitation Tip

In the Role Play, give each role a one-sentence ‘bottom line’ card so conversations stay focused on value capture rather than personalities.

What to look for

Present a short news headline about a disruption in a specific country (e.g., 'Flooding in Argentina Halts Soybean Exports'). Ask students to write down two potential consequences for U.S. consumers or the U.S. economy.

A few notes on teaching this unit

Start with a familiar product so students realize the supply chain is longer than they assumed. Use the phrase ‘geographic concentration’ deliberately when you debrief to connect spatial patterns to market power. Avoid letting the discussion drift into moral judgments of farmers versus corporations; instead, keep the focus on measurable data such as price shares and logistics bottlenecks.

Students will leave able to name at least three distinct stages in a commodity chain and explain one disruption risk per stage. They will also articulate which actors capture the greatest share of retail value and why. Evidence of this understanding appears in their maps, role-play notes, and discussion contributions.

Watch Out for These Misconceptions

• During Supply Chain Mapping, watch for students who draw a single straight line from farm to store and label it ‘local.’

  Redirect them to open the commodity chain by adding at least two intermediate nodes (e.g., seed company, refrigerated trucking, port warehouse) and mark each with country labels.

• During the Role Play, listen for students who argue that farmers deserve most of the money because they ‘work the hardest.’

  Prompt them to consult the value-distribution handout and ask which role’s profit margin most closely matches the final retail price, then have them restate their claim based on the data.
