What is meant by water surplus and water deficit in a global context?

Water surplus refers to areas where the amount of available freshwater exceeds the demand, while water deficit describes regions where the demand for freshwater surpasses the available supply. These patterns can significantly impact economic development and social well-being.

A strong answer should directly address the approved learning objective to describe global patterns of water surplus and water deficit. This question belongs to Water (optional route) within Section C: The challenge of resource management, so the response should use relevant Geography terminology, evidence, and context rather than a generic statement. The model answer is strongest when it names the key idea, links it to water surplus, and keeps the explanation inside AQA GCSE Geography 8035.
