In the context of soil degradation processes in the intensively cultivated districts of Punjab such as Sangrur and Patiala, which physical factor is primarily responsible for the rapid depletion of the shallow water table?

💡 Solution & Explanation

Intensive agricultural practices involving water-intensive paddy cultivation have led to massive groundwater extraction that far outstrips the natural monsoon recharge, causing a severe decline in the water table across central Punjab. Karstic sinkholes are absent in this region because the underlying geology consists of thick alluvial deposits rather than soluble limestone. Punjab has not experienced permanent shifts in the ITCZ that would halt regional monsoons, and current rainfall remains within historical climatic ranges. Tectonic uplift operates on geological timescales and does not account for the rapid multi-decade drop in regional groundwater levels. Monitoring groundwater depletion is critical for sustainable resource management in agrarian economies.
