Water Scarcity
The shortage of fresh water resources to meet standard water requirements, caused by over-exploitation, excessive use, and unequal access among different social groups.

Large-scale dams and reservoirs built across rivers to serve multiple objectives simultaneously, such as irrigation, hydroelectricity generation, flood control, and water supply.
Rainwater Harvesting
The technique of collecting and storing rainwater from rooftops or surface run-off for future use to recharge groundwater levels and ease water shortages.
Watershed Management
The management and conservation of surface and groundwater resources by prevention of runoff and storage/recharge of water through percolation tanks and forestation.
