Water Scarcity
The shortage of water resources to meet standard human and environmental demands, caused by over-exploitation, excessive use, and unequal access among different social groups.
Multi-Purpose River Projects
Large dams built across rivers for various uses simultaneously, such as irrigation, electricity generation, flood control, fish breeding, and inland navigation.
Rainwater Harvesting
A sustainable technique of collecting, storing, and using rainwater from rooftops or surface runoff for domestic, agricultural, and recharging groundwater purposes.
Watershed Management
The management and conservation of both surface and groundwater resources by preventing runoff and storing water through rainwater harvesting, afforestation, and check dams.
Hydrological Cycle
The continuous movement of water on, above, and below the surface of the Earth, ensuring water is a renewable resource though its availability varies spatially and temporally.

Frequently Asked Questions
Why is water scarcity increasing despite three-fourths of the Earth being covered with water?
Most of the Earth's water is saline ocean water. Out of the tiny fraction that is freshwater, much is locked in glaciers or polluted, and rapid population growth, urbanization, and industrialization have drastically increased demand.
What are the main advantages and disadvantages of multi-purpose river projects?
Advantages include irrigation, power generation, and flood control. Disadvantages include the displacement of local communities, ecological damage, submergence of vegetation, and disrupted aquatic life.
How does traditional rainwater harvesting help in Kerala?
Kerala receives abundant rainfall, but due to undulating terrain and rocky sub-structures, water runs off quickly. Traditional rooftop harvesting and farm ponds help recharge wells and ensure water availability during the dry summer months.
