Q2. Assess the contribution of floodplains to groundwater recharge and water security in the Indo-Gangetic basin. Examine the impact of anthropogenic pressures on these functions. Propose measures to restore hydrological sustainability. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question: Supreme Court has raised concerns over the increasing encroachments along the banks of the Ganga River. The court has directed the Union government, Bihar government and other relevant authorities to submit a detailed report within four weeks, outlining the status of these encroachments. Key demand of the question: The question requires an assessment of how floodplains contribute to groundwater recharge and water availability, an examination of human-induced pressures disrupting these functions, and recommendations to restore hydrological balance. Structure of the answer: Introduction: Highlight the Indo-Gangetic floodplain as a critical natural aquifer supporting millions in northern India. Body: Contribution of floodplains: Mention natural recharge, water storage, and agricultural support functions. Impact of anthropogenic pressures: Refer to urban encroachment, sand mining, pollution, and over-extraction. Measures for hydrological sustainability: Suggest scientific mapping, regulatory enforcement, recharge initiatives, and community involvement. Conclusion: Emphasise the need for integrated water management and ecological restoration to secure long-term water sustainability.
