Model Answer
Rapid urbanization and population growth have led to extensive encroachments on vacant lands and water bodies. For example, Chennai’s Pallikaranai wetlands have shrunk drastically from 15,000 acres in 1954 to just 1,500 acres by 2016. This encroachment hampers natural water retention and exacerbates the water scarcity issue.
The growth of concrete structures and impermeable surfaces in cities like Bengaluru has significantly reduced groundwater recharge. In Bengaluru, built-up areas grew from 8% in 1973 to over 93% in 2023. This extensive concretisation impedes rainwater infiltration, leading to a steep decline in groundwater levels.
Overuse of groundwater is a critical issue in cities like Chennai, which in 2023 extracted 127.5% of its groundwater resources. The rising demand for water, coupled with insufficient rainfall, leads to the depletion of aquifers.
The irregularity and concentration of rainfall during the monsoon season affect the availability of water. Bengaluru, for instance, faces water scarcity due to weak monsoons and inadequate groundwater recharge.
Untreated sewage contaminates water sources, making them unfit for consumption. Mumbai generates 3,000 million liters per day (MLD) of sewage, but only 2,100 MLD gets treated, leading to polluted water bodies.
Solutions to Address the Water Crisis
- Integrated Water Management
- Decentralized Sewage Treatment Plants (STPs)
- Adoption of Water-Saving Technologies
See lessImplementing restoration projects for lakes, ponds, and wetlands, desilting water bodies, and promoting rainwater harvesting can help recharge groundwater and increase water storage.
