Water Scarcity
The shortage of water resources to meet standard human and environmental demands, caused by over-exploitation, population growth, and unequal access.
Multipurpose River Valley Projects
Large-scale dams and reservoirs built to serve multiple objectives simultaneously, such as irrigation, hydroelectricity generation, flood control, and fish breeding.
Rainwater Harvesting
A sustainable technique of collecting, filtering, and storing rainwater from rooftops or surface runoffs for future domestic and agricultural use.
Perennial vs. Inundation Canals
Perennial canals draw water from rivers throughout the year using barrages, whereas inundation canals receive water only when rivers are in flood during the rainy season.
Watershed Management
The management of surface and groundwater resources to prevent runoff and store water through practices like afforestation and check-dams.

Frequently Asked Questions
What is the main cause of water scarcity in India?
Water scarcity is mainly caused by rapid population growth, intensive industrialization, expansion of agriculture requiring heavy irrigation, and severe pollution of water bodies.
Why are multipurpose projects called the 'temples of modern India'?
Jawaharlal Nehru called them this because they integrate development of agriculture and the village economy with rapid industrialization and urban growth.
What is the difference between drip irrigation and sprinkler irrigation?
Drip irrigation delivers water drop by drop directly near the plant roots minimizing evaporation, while sprinkler irrigation sprays water over crops mimicking natural rainfall.
