Rural Change in Developing Countries
Explain and evaluate GM crops, new technology and biofuel production in developing-country rural settings.
How to study National 5 Geography
Start from located evidence, identify the geographical process, develop each causal link and test management against the people and environments affected.
Core concepts
Concept 1
GM crops may target yield, pest resistance, nutrition or environmental stress, but seed access, dependence, biodiversity and acceptance affect outcomes.
Exam cue: State the local agricultural problem before evaluating a change.
Concept 2
Irrigation, machinery, mobile information, improved storage and other technologies can raise output or reduce loss while requiring finance, skills and infrastructure.
Exam cue: Trace benefits and costs for farmers, consumers and the environment.
Concept 3
Biofuel crops can create markets, jobs and energy supply but may compete with food, land, water and ecosystems.
Exam cue: Use scale, access and affordability to avoid a one-size-fits-all judgement.
Risk pitfalls and guardrails
Assuming a higher-yield seed guarantees food security.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Ignoring maintenance and water or energy requirements.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Treating all biofuel production as carbon-neutral.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Memory anchors
GM evaluation
Trait, yield or resilience benefit versus cost, access, dependence and ecological risk.
Irrigation trade-off
More dependable water can raise output but may deplete supplies or salinise soils.
Mechanisation trade-off
Faster work and higher output versus capital, fuel, repair and employment effects.
Post-harvest technology
Storage, cooling and transport can reduce loss and improve market access.
Biofuel benefit
A crop can supply energy, income, processing and employment.
Biofuel risk
Fuel production may compete with food, land, water or habitats.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
