Biofortification is emerging as a key strategy to combat hidden hunger in India. Examine its scientific basis and implementation challenges.

Q. Biofortification is emerging as a key strategy to combat hidden hunger in India. (15 marks, 250-350 words)

"Hidden hunger" is micronutrient deficiency — of iron, zinc or vitamin A — persisting even where calorie intake is adequate. Biofortification, the breeding of higher nutrient density into staple crops, addresses it at source; ICAR released 29 biofortified varieties among 386 improved varieties in the past year [1], signalling its mainstreaming.

Scientific basis - Conventional breeding: high-nutrient germplasm is crossed into high-yielding backgrounds, fixing iron, zinc, protein and vitamin A enrichment genetically in the seed [1]. - Agronomic route: micronutrient-enriched fertilizers raise grain concentration where soils are deficient. - Molecular/transgenic route: used where natural genetic variation for a nutrient is absent in the crop. - Delivery logic: the nutrient travels inside the staple already consumed daily, requiring no dietary behaviour change — unlike supplementation or fortification, which need continuous supply chains. - Convergence with climate goals: ICAR's varietal pipeline is 94% climate-resilient [1], allowing nutrition and stress-tolerance traits to be stacked in a single release.

Implementation challenges - Seed multiplication and last-mile reach: technologies reached roughly one crore farmers directly [1] — a fraction of India's farm households; breeder-to-certified seed chains remain thin. - Absent price signal: biofortified grain is visually indistinguishable, attracts no MSP premium, and procurement agencies do not segregate it, so farmers see no return. - Consumer acceptance: altered colour or taste (orange sweet potato, yellow maize) meets resistance in staple-conservative diets. - Nutrient retention: milling, polishing and cooking losses, plus poor bioavailability from phytate-rich diets, dilute on-plate gains. - Institutional capacity: research is spread across 113 ICAR institutes and 74 agricultural universities [2], but extension — not laboratory capability — is the weak link. - Regulatory delay constrains the transgenic pathway.

Biofortification is scientifically sound and cost-effective, yet its impact rests on delivery rather than discovery. Embedding biofortified staples into PDS, ICDS and PM POSHAN procurement, coupled with seed-village programmes and a targeted price incentive, would convert varietal releases into measurable nutritional outcomes — advancing food and nutritional security under the Viksit Bharat 2047 vision.
