GROUNDWATER MINING: What happens when an aquifer runs out of water ?

Groundwater minining consists in extracting water from the ground at a faster rate than the water supply can be recharged. The most immediate consequence of this overxploitation of a reservoir is that it will sooner or later run out of water. But that is not all, groundwater mining has more far reaching and sometimes even surpising consequences. In this short video we will first discuss aquifers and look at how water arrives and moves underground. We will then look at how grounwater mining affects aquifers, but also the flow of water flowing in rivers and the very ground below our fields or cities. After watching this video you will understand why it's important to manage our groundwater resources sustainably in order to avoid negative economic, environmental and social repercussions.

I love your channel so much, I just watched all of your videos. I'm looking forward for the next one :)

Very informative video.Mostly in all cities of India there is no space for water permeability.Every space is laid with concrete roads and highrise buildings.where is the space for water to percolate in ti the ground.Governments should seriously think about this.otherwise there will be a severe drought in water.All living beings will die
