How far do you agree that the behaviour of the Indian monsoon has been changing due to humanizing landscape? Discuss.

Topic: Geophysical Phenomena. Syllabus: Important Geophysical phenomena such as earthquakes, tsunami, volcanic activity, cyclone etc., geographical features and their location-changes in critical geographical features (including water-bodies and ice-caps) and in flora and fauna and the effects of such changes. Same official PYQ from year-wise 2015 and Geophysical Phenomena.

Revision summary

The monsoon is still an ocean–continent wind system at heart. Deforestation, irrigation, cities, and aerosols change local rain, onset, and extremes. Urban heat can mean heavier short storms; sealed soil turns them into floods. El Niño, the Indian Ocean, and greenhouse warming remain major controls. Agree in part: humans reshape monsoon behaviour, they do not solely own it.

  L[Forest to farm city irrigation] --> M[Local monsoon rain]
  A[Aerosols heat islands] --> M
  O[ENSO IOD ocean heat] --> M
  G[Global warming] --> M
  M --> V[More extremes variable spells]

Conclusion

  • Restore Ghats and catchment forests, cut aerosols, and plan cities for cloudbursts, while still watching the Pacific and Indian Oceans in the forecast.

Humanized landscapes have changed how monsoon rain falls on the ground—more bursts, more urban storms, some local drying after forest loss, and aerosol effects on clouds. That is a real but partial story. The monsoon’s large behaviour still answers to oceans and a warming planet. The fair agreement is “yes, in part, and growing,” not “the monsoon is now only a land-use product.”

Q1 · UPSC Mains 2015 · GS I · 12 marks

The ancient civilization in Indian sub continent differed from those of Egypt, Mesopotamia and Greece in that its culture and traditions have been preserved without breakdown to the present day. Comment.

Indian Heritage and Culture

India kept Sanskrit–Prakrit–vernacular, pilgrimage, and dharma as living practice. Egypt, Mesopotamia, and Greece lost their old public cults after conversion and empire. Harappan script is still unread, so the oldest urban layer is not a proven straight line. Islam, colonialism, and Partition remade custom even while older forms survived. The comment is fair as relative continuity, not as zero breakdown.

Q2 · UPSC Mains 2015 · GS I · 12 marks

Mesolithic rock cut architecture of India not only reflects the cultural life of the times but also a fine aesthetic sense comparable to modern painting. Critically evaluate this comment.

Indian Heritage and Culture

Mesolithic India left painted and engraved shelters, not cave temples. Bhimbetka and related sites show hunt, dance, and animals. Rock-cut architecture belongs to Mauryan and later religious caves. The line can look modern to us, but the makers had ritual and group aims. The comment is fair on culture, weak on architecture and on equating two art worlds.

Q3 · UPSC Mains 2015 · GS I · 12 marks

How difficult would have been the achievement of Indian independence without Mahatma Gandhi?

The Freedom Struggle

Gandhi built mass satyagraha from Champaran to Quit India and a daily constructive programme. Non-violence and a wide Congress made bargaining with Britain possible as a national claim. War, INA, peasants, and British weakness would still have pushed decolonisation. Partition shows his limits on communal peace. Without him freedom would likely have been bloodier and less united, not unthinkable.
