Over-Abstraction - GCSE Geography Definition

Over-abstraction refers to the process of taking too much water from natural sources like rivers, lakes, or underground stores called aquifers. This happens when the demand for water is higher than the supply. This means that more water is taken than can be naturally replaced by rainfall or by flowing back into the source. Over-abstraction can lead to problems such as the drying out of rivers and lakes, lower water levels in wells, the reduction of the water table, and damage to ecosystems that rely on the water. It can also cause issues for people, as there may not be enough water available for drinking, farming, or other uses. In geography, understanding over-abstraction is important because it helps us learn how to manage water resources sustainably and protect the environment.
