Give an example of how sustainable development can be applied in agriculture.

An example of sustainable development in agriculture is the use of crop rotation. This practice helps maintain soil fertility and reduces the need for chemical fertilizers, ensuring that the land remains productive for future generations.

A strong answer should directly address the approved learning objective to define sustainable development as meeting current needs without preventing future generations from meeting their needs. This question belongs to Using the Earth's resources and sustainable development within Using the Earth's resources and obtaining potable water, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to sustainable development, and keeps the wording specific to AQA GCSE revision.
