Answer :

Water harvesting is a technique used to collect and store water for future use. It means capturing the rainfall when it falls or capturing the water that runs off.


Advantages:


It helps provide water in time of need or scarcity.


It helps in preserving and replenishing the groundwater.


Causes for the failure of sustained availability of groundwater:


Loss of vegetative cover and deforestation.



Trees release water vapor into the atmosphere, fewer trees means less rainfall, which disrupts the groundwater level.


Pollution of groundwater by industries and urban waste.



Groundwater contamination occurs when industrial pollutants and chemicals get into the groundwater and cause it to become unsafe and unfit for human use.
