Groundwater, the hidden source of life

  • Fresh water makes up less than 1 % of all water on earth. Of this 1 %, 99 % is groundwater.
  • An aquifer is an underground water reservoir.
  • Some aquifers are depleted by overuse, with a rate of meters per year.
  • Dangers of pollution of groundwater.

Understanding groundwater, a project in India


When we have small gardens, we may forget how important groundwater is. This first video tells about confined and unconfined aquifers, groundwater over-exploration and well inventorization, or to inventorize wells in an area.


Second video about a groundwater study in India. As a gardener or farmer we should understand the mechanics of groundwater.
Some topics in this video:

  • Drawdown of groundwater when water is pumped.
  • Recharge of groundwater through rain.
  • Discharges of groundwater by pumping and other mechanisms.
  • Mineralization of groundwater.
  • Salinization of groundwater and soils.
