Frequently Asked Questions
Why is water scarcity increasing in India despite having major river systems?
Water scarcity is rising due to rapid population growth, intensive agriculture requiring heavy irrigation, industrial pollution, and unequal spatial and temporal distribution of rainfall.
What is the difference between rainwater harvesting and watershed management?
Rainwater harvesting specifically focuses on capturing and storing rainwater for immediate or future use, whereas watershed management is a broader approach that manages all water and land resources within a river basin.
What are the main causes of groundwater pollution in India?
Groundwater pollution is primarily caused by the excessive use of chemical fertilizers and pesticides in agriculture, industrial effluent discharge, and untreated urban sewage seeping into aquifers.
