EXAMINER REASONING
Agricultural revolutions are a classic UPSC topic - they connect geography, economics, and policy. Prelims tests: the colour-revolution mapping (Green=wheat, White=milk, Blue=fisheries, Yellow=oilseeds, etc.), key persons (Norman Borlaug, Dr. M.S. Swaminathan, Verghese Kurien), and the years/phases. Mains demands: (a) comparative analysis of the revolutions - what each achieved, (b) the Green Revolution's regional impact - why Punjab, Haryana, and Western UP benefited most, (c) the negative externalities - groundwater depletion, soil degradation, chemical fertiliser dependence, (d) the second Green Revolution and Evergreen Revolution concept, (e) the role of cooperatives in Operation Flood. The examiner's favourite framing is: "Has the Green Revolution become a victim of its own success?"
