What to Focus On
- Three-fourths of Earth is covered with water, but only a small proportion is freshwater suitable for use.
- Freshwater is obtained from surface run-off and groundwater, renewed through the hydrological cycle.
- By 2025, nearly two billion people are predicted to live in absolute water scarcity.
- Dams are classified by structure (timber, embankment, masonry) and height (low, medium, high).
- Multi-purpose projects serve irrigation, power generation, flood control, recreation, navigation, and fish breeding.
- Bhakra-Nangal project serves both hydel power and irrigation; Hirakud integrates water conservation with flood control.
- Rainwater harvesting is the collection and storage of rainwater for direct use or groundwater recharge.
- Traditional techniques include guls/kuls (Himalayas), tankas (Rajasthan), johads and khadins (Rajasthan), and inundation channels (Bengal).
- Tankas are underground cisterns in Rajasthan houses; rainwater called 'palar pani' is considered the purest water.
Common Mistakes to Avoid
Water is not scarce because three-fourths of Earth's surface is covered with water and it is a renewable resource.
Dams are purely beneficial structures — they only help with irrigation, flood control, and electricity, with no negative consequences.
Water scarcity only occurs in areas with low rainfall or drought-prone regions like Rajasthan.
Memory Tips
Only a small fraction of Earth's water is usable freshwater
Three main causes of water scarcity: over-exploitation, excessive use, unequal access
Irrigated agriculture is the LARGEST consumer of water
Multipurpose river projects serve: irrigation, electricity, domestic/industrial water, flood control, recreation, inland navigation, fish breeding
