Q5. Consider the following statements regarding geostrophic winds and planetary atmospheric dynamics:
1. Geostrophic wind represents a theoretical wind that blows parallel to straight isobars in the upper atmosphere.
2. It occurs when the horizontal pressure gradient force is balanced equally by the apparent Coriolis deflection force.
3. In the boundary friction layer near the Earth's surface, winds blow precisely parallel to isobars without crossing them.

💧 WATER WEALTH
Punjab’s Groundwater Crisis

💡 KEY INSIGHT
Groundwater depletion is raising irrigation costs and disproportionately affecting small farmers.

🔑 KEY TAKEAWAYS

→ Groundwater extraction: 152%
→ 72% assessment blocks in the red zone
→ Rice-wheat farming drives groundwater demand
→ Subsidies and assured procurement sustain water-intensive crops
→ Falling water tables increase farmers’ costs

🚀 WAY FORWARD

→ Promote crop diversification
→ Reform groundwater & electricity incentives
→ Strengthen collective irrigation
→ Improve market support for alternative crops
→ Protect small and tenant farmers
