Water scarcity is primarily driven by rapid population growth, expanding agricultural demand, intensive groundwater pumping, and severe pollution of water bodies due to untreated industrial and domestic effluents.
What is the difference between watershed management and rainwater harvesting?
Watershed management is a holistic approach focusing on the overall management of land and water resources within a drainage basin, whereas rainwater harvesting specifically refers to collecting and storing rainwater from rooftops or surface runoffs.
How does agriculture consume the highest share of water in India?
Agriculture requires massive amounts of water for crop irrigation, especially for water-intensive crops like paddy and sugarcane, compounded by traditional inefficient flood-irrigation techniques.
