Key Points
Key Points: Need to Conserve Water
- Rising demand for water due to population growth, irrigation and industrialisation has reduced groundwater levels.
- Overexploitation of groundwater leads to a lowering of the water table.
- Loss of vegetation reduces rainfall and increases drought conditions.
- Agriculture uses more than 90% of freshwater, increasing pressure on water resources.
- Pollution of rivers, lakes and groundwater makes water unfit for direct use, increasing water scarcity.
