Q. El Niño's impact on Indian agriculture is probabilistic, not deterministic. Critically examine this statement in light of historical data and suggest policy measures for building monsoon-resilient agriculture. (15 marks, 250-350 words)

El Niño — anomalous warming of central and eastern Pacific waters — weakens the Walker Circulation and suppresses the Indian summer monsoon, on which over half of India's cropped area depends. Yet the historical record shows it raises risk rather than guarantees drought, making the statement largely valid.

Evidence supporting the probabilistic view - Since 1950, of 16 El Niño years, only 7 recorded below-normal all-India monsoon rainfall — roughly a 44% co-occurrence, far short of determinism [1]. - Onset date is not season outcome: the 2019 season began late yet closed above normal; in 2026 onset came on 4 June against a normal date of 1 June, but this alone does not fix the seasonal total [2]. - Offsetting drivers — a positive Indian Ocean Dipole, Madden-Julian Oscillation activity and intraseasonal breaks can partly neutralise Pacific forcing, which is why IMD issues a joint ENSO-IOD bulletin [3].

Where determinism partially holds - Event intensity matters: strong El Niños align with the classic drought years of 1987, 2002, 2009 and 2015; distribution and timing of rain, not just totals, decide yields. - For 2026, IMD's updated long-range forecast places seasonal rainfall at 90% of LPA — below normal, with El Niño conditions likely during the season [4]. - Spatially uneven risk: FAO's satellite-based stress analysis flags South and Southeast Asia among the highest-risk regions [5].

Policy measures for monsoon-resilient agriculture - Expand micro-irrigation and watershed recharge to cut rainfed dependence; strengthen reservoir and groundwater accounting. - Scale district-level contingency crop plans promoting short-duration and climate-resilient varieties. - Deepen crop insurance penetration under PMFBY with faster, technology-based claim settlement [6]. - Improve probabilistic forecast communication so advisories convey risk ranges, not binary predictions.

Thus El Niño is best read as a risk multiplier within a multi-factor climate system. Treating it probabilistically shifts policy from reactive drought relief toward anticipatory resilience — aligning with SDG-2 (Zero Hunger) and SDG-13 (Climate Action) and reaffirming that preparedness, not prediction alone, secures Indian agriculture.
