Question

BlackTom AI · Accepted Answer

Bruce Davidson argued successful farming in Australia must use large land areas, use little labour, be produced for export markets, and be sufficiently valuable to be able to be exported profitably.

1. Relevant knowledge points and concepts
- Australian environmental and economic context: low population density, vast land, variable rainfall, long transport distances to global markets. 
- Economies of scale: large areas spread fixed costs and make extensive farming viable. 
- Labour scarcity and high wages in remote areas favor mechanisation and low-labour systems. 
- Export orientation: domestic demand is limited by low population; profits often depend on export markets. 
- Commodity value vs transport cost: products must be valuable enough per unit to absorb freight and still return profit.

2. Step-by-step reasoning
- Large land areas: Because much of Australia is semi-arid and yields per hectare are low, profitable production often requires extensive acreage to achieve sufficient total output. 
- Little labour: Sparse rural populations and high labour costs incentivize mechanised, low-labour operations (e.g., broadacre cropping, sheep grazing). 
- Produced for export markets: Domestic market size is small relative to production potential; farms target overseas demand to obtain scale and price stability. 
- Sufficiently valuable to export profitably: Long transport distances mean bulk, low-value products can be uneconomic to export unless they have adequate value-to-weight ratios or receive processing that raises value.

3. Calculations
- No numerical calculation is required for this conceptual question. The economic logic above serves as the “proof.”

4. Why the correct answer is correct
- The listed four conditions directly follow from the environmental constraints and economic incentives in Australia, matching Davidson’s criteria for commercially viable farming in that country.

5. Why other options are incorrect
- Option A (irrigation, lots of capital, have a market, use little labour): Irrigation and high capital are not universally required; many Australian farms are extensive and dryland. 
- Option C (irrigation, meet domestic markets, require little capital, require little land): Contradicts reality—many enterprises need large land and target export markets rather than just domestic. 
- Option D (large land, little capital, lots of labour): Labour requirement is incorrect—labour is typically minimized, not maximized.

6. Conclusion
The correct choice is: must use large land areas, use little labour, be produced for export markets, be sufficiently valuable to be able to be exported profitably — which matches the provided answer.
