Here are some false statements. Identify the mistakes and rewrite them correctly.
(a) Multiplying urban centres with large and dense populations and urban lifestyles have helped in proper utilisation of water resources.
(b) Regulating and damming of rivers does not affect the river’s natural flow and its sediment flow.
(c) Today in Rajasthan, the practice of rooftop rainwater water harvesting has gained popularity despite high water availability due to the Indira Gandhi Canal.
Answer:
Statements:
(a) False Statement:
“Multiplying urban centres with large and dense populations and urban lifestyles have helped in proper utilisation of water resources.”
✅ Corrected Statement:
“Multiplying urban centres with large and dense populations and urban lifestyles have led to excessive and often wasteful utilisation of water resources.”
Explanation:
Urbanization increases water consumption, leading to over-extraction of groundwater, pollution, and inefficient usage, rather than proper utilization.
(b) False Statement:
“Regulating and damming of rivers does not affect the river’s natural flow and its sediment flow.”
✅ Corrected Statement:
“Regulating and damming of rivers affects the river’s natural flow and disrupts its sediment flow.”
Explanation:
Dams and river regulation alter the natural flow, causing sediment deposition, erosion downstream, and affecting aquatic ecosystems.
(c) False Statement:
“Today in Rajasthan, the practice of rooftop rainwater harvesting has gained popularity despite high water availability due to the Indira Gandhi Canal.”
✅ Corrected Statement:
“Today in Rajasthan, the practice of rooftop rainwater harvesting has gained popularity due to water scarcity, despite the availability of water from the Indira Gandhi Canal.”
Explanation:
Rajasthan is an arid region, and despite the Indira Gandhi Canal, water scarcity persists. People still rely on traditional rainwater harvesting methods for local water needs.
