How was India benefitted from the contributions of Sir M. Visvesvaraya and Dr. M. S. Swaminathan in the fields of water engineering and agricultural science respectively? (Answer in 150 words)

Sir M. Visvesvaraya represented scientific water management and industrial modernisation, while Dr. M. S. Swaminathan advanced science-led food security.

Visvesvaraya’s contribution

• His irrigation, flood-control and reservoir engineering strengthened water management and drought protection.
• He promoted planned industrialisation, technical education and efficient public works.

Swaminathan’s contribution

• As a leading architect of India’s Green Revolution, he helped adapt high-yielding varieties with irrigation, fertiliser and extension.
• His work improved foodgrain production, reduced import dependence and supported national food security.
• He later emphasised evergreen revolution principles: productivity with ecological sustainability, nutrition and small-farmer welfare.

Conclusion

Both combined applied science with public purpose. Their legacy now requires water efficiency, climate-resilient crops, biodiversity protection and equitable access to technology.
