In GCSE Geography students will look at some of the uses we have for water, such as agriculture or waste disposal. They will also study some of the causes of water shortages, for example climate change or the rise in population.

Lack of clean water creates several problems. The initial lack of clean water leads to water pollution which in turn leads to diseases being spread via the water supply.
