Activities & model answers

Activity 1 — Classify the agriculture types

Key

Shifting cultivation = subsistence / extensive (tropical rainforest); pastoral nomadism = subsistence / extensive (arid lands); extensive commercial grain = commercial / extensive (Prairies, wheat belt); market gardening = commercial / intensive (near cities); Mediterranean = commercial (moderately intensive, tree/vine crops; Med. Basin, California, S Australia); plantation = commercial (tropics — coffee/tea/rubber).

Activity 2 — Subsistence vs commercial

Key

Subsistence: purpose = feed the family; small scale, low inputs; simple/traditional tools; dominates the developing world & marginal environments (e.g. parts of Africa, S/SE Asia). Commercial: purpose = sell for profit; larger scale, capital/machinery; modern methods; dominates developed economies & export regions (e.g. Canadian Prairies).

Activity 3 — Describe & explain the spatial pattern

Look for

Describe: extensive commercial in mid-latitude interiors (Prairies, Pampas, Australian belt); plantations ringing the tropics. Explain: climate sets limits (temperate grassland soils/rainfall for grain; tropical warmth/rain for plantation crops); human factors — flat cheap land + machinery + export markets for extensive; colonial history + tropical labour + world demand for plantations.

Activity 4 — Evaluate the environmental impacts

Model

A balanced answer notes real harms (soil erosion/salinity, water depletion — irrigation ≈70% of freshwater use (FAO); biodiversity loss from monoculture/clearing; GHG emissions ≈ a fifth to a quarter of the global total (IPCC/FAO); about a third of food lost or wasted (FAO)) AND that agriculture feeds billions and can improve (precision farming, drought-tolerant varieties, cutting waste). "Evaluate" = reach a judgement, not just list.

Activity 5 — Key concepts

Indicative

Environment = climate/soil decide which system suits a place; Space = systems form a distinct global distribution; Interconnection = plantations tie tropical growers to world markets; Change = farming evolved Neolithic → Green Revolution → precision; Sustainability = agriculture both drives and is threatened by climate change.

Key questioning (with answers)

Q: What separates extensive from intensive farming? Inputs of labour/capital per hectare — extensive spreads low inputs over a huge area (high total, low per-hectare output); intensive concentrates high inputs on a small area (high per-hectare yield).
Q: What was the Green Revolution? The mid-20th-century adoption of high-yield crop varieties, irrigation, and synthetic fertilisers/pesticides that greatly raised yields (esp. in Asia & Latin America), with ecological side-effects.
Q: How is agriculture linked to climate change? It's a major emitter (agriculture, forestry & land use ≈ a fifth to a quarter of GHGs — IPCC/FAO) via livestock, rice, fertiliser & clearing; and climate change threatens yields through shifting rainfall, drought & extremes.

Differentiation

Support: pre-filled first row of the Activity 1 table; a labelled base map for the mapping task; sentence starters for Activity 4.
Extension: research a fourth system (e.g. intensive rice/paddy in monsoon Asia) or evaluate whether the Green Revolution was, on balance, positive.
EAL/D: visual glossary (subsistence, commercial, extensive, intensive, monoculture, Green Revolution).

Assessment & homework

Exit ticket: name one system + its typical location + one reason it's found there.
Homework: write up the Activity 4 evaluation; read ahead to the next 7.x economic-activity chapter.

Teaching note — accuracy & precision. Keep the big statistics as attributed ranges, not false precision: "about a third of food is lost or wasted (FAO)"; "roughly a fifth to a quarter of GHG emissions (IPCC/FAO)"; irrigation "about 70% of freshwater use (FAO)". Present the Green Revolution and intensification as trade-offs (yields vs environment), not simple good/bad. The figures here are illustrative schematics — use FAO/ABARES maps for real distributions.
