Navigating Bengaluru's Water Crisis: A Scientific Perspective

Bengaluru, once revered as the Garden City, now grapples with a dire water scarcity predicament, a departure from its verdant past. The transition from abundance to scarcity finds its roots in a confluence of scientific intricacies and urban dynamics: 1. Unraveling Rainfall Patterns : Bengaluru's historical reliance on monsoon rains for replenishing water bodies is being challenged by unpredictable rainfall patterns. Variability in timing, intensity, and duration of rainfall events disrupts the natural recharge of lakes and groundwater aquifers. As a result, the city faces periods of water scarcity amidst diminishing replenishment of its water reserves. 2. Aquifer Dynamics and Over-Extraction : The city's growing population and urban expansion have led to a surge in groundwater extraction, primarily through borewells. However, this relentless pumping has exceeded the recharge capacity of aquifers, leading to a decline in water tables. As groundwater levels plummet, borewells yi...
