Specification 3.2.3.2 · Paper 2
The amount of agricultural produce harvested from a given area of land.
Revise: Global Patterns and Impacts of Food InsecurityFood supply depends partly on crop yield: the amount harvested from a given area. Crops need suitable temperatures and enough water at the right times. Extreme temperatures can restrict growth, while drought reduces the water available to plants.
For an explanation, develop a chain: drought reduces crop yields, so less food reaches markets and prices may rise.
Explain factors through a chain: drought reduces water available for irrigation, lowering crop yields and reducing food availability.

Revise: Food Security DefinitionsThese factors affect crop yield: the amount produced per unit area of farmland. A lower yield means less food from the same area, not necessarily less land being farmed.
