What to Focus On

  • Water is essential for life and development.
  • Only 3% of Earth’s water is freshwater.
  • India has 4% of global freshwater for 16% of the world’s population.

  • Four sources: surface, underground, atmospheric, and oceanic water.
  • Only surface and underground water are used by humans.
  • Groundwater depends on rainfall, soil type, and land slope.

  • Water budget is the balance between supply and demand.
  • Irrigation accounts for about 81% of total water use.
  • Water demand is rising due to population and development.

Common Mistakes to Avoid

India has plenty of water because 70% of Earth's surface is water, so there's no real water crisis.

Groundwater is infinite and gets replenished every year, so overuse is not a problem.

Canal irrigation is the most common method in India, so it must be the largest source of irrigation.
