Punjab groundwater crisis: What it will take to move from paddy to maize -Anju Agnihotri Chaba

At current rates of depletion, Punjab’s entire subsurface water resource could be exhausted in a little over two decades.

Jalandhar:
As the discussion around Punjab’s massive groundwater crisis becomes more urgent, there is an increasingly stronger accent on diversification of crops, and a move away from water-guzzling paddy.

At a meeting over the weekend, Punjab Agricultural University (PAU), Ludhiana, decided to strengthen maize — the most important alternative to rice — by working towards narrowing the gap in economic returns between the two crops. The idea is to nudge farmers towards increasing the area under maize.

Over 70% of blocks in Punjab are in the dark zone on underground water stocks, according to central government estimates. At current rates of depletion, Punjab’s entire subsurface water resource could be exhausted in a little over two decades.

To conserve the resource, the Punjab government brought a law in 2009 to mandatorily delay transplantation of paddy beyond June 10, when the most severe phase of evapotranspiration is over. This law has been blamed for creating the bad air crisis of North India — especially Delhi — by delaying harvesting to end-October and early November, when atmospheric and wind conditions cause particulate matter and gases from burning paddy stubble to hang close to the surface.
