What students need to be able to do

• Describe which parts of the world produce more food than their populations need (making them food-secure) and which fall short (leaving them food-insecure), using global variations in calorie intake and in food supply as the evidence for that pattern.
• Explain why global food consumption is rising, covering both economic development (as incomes rise, diets change and demand increases, including for more resource-intensive foods) and population growth.
• Explain how each of the following factors can affect a place's food supply: climate (suitability for growing crops and its variability), technology (access to modern farming methods and inputs), pests and disease (crop and livestock losses), water stress (availability of water for irrigation and livestock), conflict (disruption to farming, distribution and trade), and poverty (ability to afford food, inputs or imports).
• Explain the range of impacts that food insecurity can cause: famine, undernutrition, soil erosion (from overworking land under pressure to produce more), rising food prices, and social unrest.
• Give an overview of strategies used to increase food supply: irrigation; aeroponics and hydroponics (growing without soil); the technology and techniques associated with a "new green revolution" and biotechnology; and appropriate technology (methods suited to the skills, resources and needs of the local population using them).
• Use a named example of a large-scale agricultural development to explain both the advantages it has brought and the disadvantages or drawbacks associated with it: flagged here as a required named example; the specific real-world scheme is composed separately at bundle-build time, grounded in this requirement.
• Explain the range of approaches that can move food supply towards a more sustainable future: organic farming; permaculture (designing food production to work with natural ecosystems rather than against them); urban farming initiatives; sourcing fish and meat sustainably; eating food in season; and reducing waste and losses across the food chain.
• Use a named example of a local scheme in a lower-income country or newly emerging economy that increases sustainable food supply, and explain how it does so: flagged here as a required named example; the specific real-world scheme is composed separately at bundle-build time, grounded in this requirement.

Case studies and examples needed

• A large-scale agricultural development, used to show both its advantages and its disadvantages.
• A local scheme, based in a lower-income country (LIC) or newly emerging economy (NEE), that increases sustainable food supply.

Geographical skills used

• Interpreting choropleth or graduated-symbol maps showing global food surplus/deficit patterns.
• Reading and comparing statistical data on calorie intake, production, or consumption trends over time.
• Interpreting diagrams of specific technologies (e.g. a labelled hydroponics or irrigation system).

Where students go wrong

• Assuming food insecurity is caused by a single factor (usually climate), rather than understanding it typically results from several factors interacting together.
• Confusing "increasing food supply" strategies (which raise the amount produced) with "sustainable food supply" strategies (which aim to keep supply reliable without depleting resources): these are two distinct parts of the specification, not one blended list.
• Assuming a large-scale agricultural development only has advantages, and overlooking the environmental or social disadvantages the specification specifically requires alongside them.
• Believing hydroponics and aeroponics are the same technique, rather than distinguishing hydroponics (growing in a nutrient-rich water solution) from aeroponics (growing with roots suspended in air and misted with nutrients).
• Assuming sustainable food strategies are only relevant to lower-income countries, rather than recognising organic farming, permaculture, and reduced-waste approaches apply just as much in higher-income contexts.

How it gets asked in the exam

"Explain why global demand for food is increasing", "Explain how [a named factor] can affect food supply", "Explain one advantage and one disadvantage of [named agricultural development]", "Assess the extent to which [named local scheme] provides a sustainable food supply", "Suggest reasons why some strategies to increase food supply may not be sustainable".

Key vocabulary

Food security, food insecurity, calorie intake, food surplus, food deficit, famine, undernutrition, soil erosion, irrigation, aeroponics, hydroponics, green revolution, biotechnology, appropriate technology, agribusiness, organic farming, permaculture, urban farming, sustainable sourcing.

Assumed prior knowledge

• Resource Management Overview (this taxonomy's topic 15), particularly the general point that resource demand and supply are not evenly matched globally.
• General awareness from KS3 geography of what economic development and population growth mean at a basic level, since both are used here as reasons for rising consumption.

How Speca scaffolds this topic

• Use a consistent factor-sorting grid (climate / technology / pests and disease / water stress / conflict / poverty) as a recurring scaffold across explanation tasks, since the six-factor list is a common source of confusion when introduced as unstructured prose.
• Provide a clear two-column "increase supply vs. sustainable supply" table populated with each named strategy, so students don't conflate the two strategy types.
• For the two required named examples, use a single consistent advantages/disadvantages (or "how it works / why it's sustainable") template reused across both, so the skill of writing about a case study transfers rather than being relearned per example.
• Pre-teach "aeroponics," "hydroponics," "permaculture" and "biotechnology" as a small illustrated vocabulary set before using them in fuller explanations.
