Biofortification
Topic: Agricultural Marketing, MSP, Buffer Stocks and PDS · NCERT: Beyond NCERT
Meaning
Biofortification is the breeding of food crops so that their edible parts (the grain, seed or root) naturally contain more micronutrients, which are vitamins and minerals such as iron, zinc and vitamin A. Examples are ICAR's zinc-rich wheat and iron-rich pearl millet (bajra).
It matters because India's main nutrition problem is no longer only too few calories. It is hidden hunger: people eat enough rice or wheat but still lack iron, zinc and other micronutrients. Biofortification puts the missing nutrients inside the crop itself, so people get them from the food they already eat.
Explanation
How it works
- Scientists pick plant varieties that naturally take up more of a micronutrient, such as iron or zinc, from the soil.
- They cross these plants with high-yielding varieties. The goal is a new variety that gives good yield and more nutrients.
- The farmer grows it like any other seed. The extra nutrient is already inside the grain, so nothing is added after harvest.
- One-time cost, lasting benefit:
- The research cost is paid once, when the variety is bred.
- After that, farmers can grow the variety and pass on its seed season after season.
- So it reaches remote rural families who buy little processed or packaged food.
Ways to biofortify a crop (textbook types)
- Conventional plant breeding: crossing and selecting plants. This is how ICAR's zinc-rich wheat and iron-rich bajra were bred.
- Agronomic biofortification: adding micronutrients, such as zinc fertiliser, to the soil or leaves so the grain absorbs more.
- Genetic engineering (transgenic): putting a gene from another organism into the crop. This is a GM route, and it faces separate regulatory and public debates.
What makes it work or fail
- Works better when:
- farmers adopt the seed widely;
- yields are as good as those of normal varieties;
-
the grain enters common meals and public schemes such as the PDS.
-
Held back when:
- farmers have no reason to switch, because the market pays the same price for normal grain;
- seed supply is weak;
- people's bodies cannot absorb the nutrients. This is the utilisation pillar of food security, which needs clean water, sanitation and health.
Illustrative example: calories without nutrition
- A priority household (PHH) of 4 gets 4 × 5 = 20 kg of grain a month under NFSA.
- This covers a large share of the family's calories.
- If the grain is ordinary rice or wheat, the family can still lack iron and zinc. That is hidden hunger.
- If the same 20 kg came from a biofortified variety, the family would get more micronutrients without changing what it eats or spends.
In India
- Who breeds the varieties: ICAR (Indian Council of Agricultural Research) develops biofortified crops. Examples include zinc-rich wheat and iron-rich pearl millet.
- Latest figure: 109 varieties were released in 2024, including biofortified ones.
- Why it is needed (NFHS-5, 2019-21):
- Anaemia (low haemoglobin in the blood, often caused by iron deficiency) affects 57% of women aged 15–49, 67% of children aged 6–59 months and 52% of pregnant women [2].
-
35.5% of children under 5 are stunted, meaning they are too short for their age. This is a sign of long-term undernutrition.
-
Where it fits in policy:
- The PDS was built on calories (rice and wheat bought at MSP), not nutrition.
- Biofortification sits alongside fortified rice, the other major policy response to hidden hunger.
- The CCEA (Cabinet Committee on Economic Affairs) approved a phased roll-out of fortified rice in April 2022. Coverage became universal across TPDS, ICDS, PM POSHAN and other welfare schemes by March 2024 [2].
-
In October 2024, the Cabinet approved free fortified rice from July 2024 to December 2028 [1].
-
Millets link: iron-rich bajra fits with the idea of adding local millets to the PDS instead of only rice and wheat, which the note gives as an example of food sovereignty.
Don't confuse with
- Food fortification (e.g. fortified rice): nutrients are added after harvest, during processing. Fortified rice has kernels with added iron, folic acid and vitamin B12 mixed into normal rice. In biofortification the nutrient is bred into the plant while it grows.
- Supplementation: nutrients are given directly as tablets or syrups, for example iron tablets. This is not a food or crop-based method.
- GM crops: biofortification can use genetic engineering, but ICAR's zinc-rich wheat and iron-rich bajra come from conventional breeding. Biofortified does not mean genetically modified.
- Food security vs nutrition security: food security is about enough, safe and nutritious food for everyone. Nutrition security adds a balanced diet with enough micronutrients, plus clean water, sanitation and healthcare. Biofortification is a nutrition security tool.
Prelims Hooks
- Biofortification = breeding crops to naturally carry more micronutrients. Examples: ICAR's zinc-rich wheat and iron-rich pearl millet (bajra). 109 varieties were released in 2024, including biofortified ones.
- Hidden hunger = lack of micronutrients such as iron, zinc, iodine or vitamin A, even when a person eats enough calories.
- Trap: fortified rice is fortification, not biofortification. It carries iron + folic acid + vitamin B12, became universal in government schemes by March 2024 [2], and was continued to December 2028 [1].
- NFHS-5 (2019-21): anaemia in 57% of women aged 15–49, 67% of children aged 6–59 months and 52% of pregnant women [2]. 35.5% of children under 5 are stunted.
- GHI trap: the four indicators are undernourishment, child stunting, child wasting and under-5 mortality. Anaemia and micronutrient deficiency are NOT indicators.
- Biofortification targets the nutrition side of food security. Its benefit depends on the utilisation pillar, which needs clean water, sanitation and health.
Mains Points
- From calorie security to nutrition security (GS-II/III):
- The PDS delivers rice and wheat, yet 57% of women are anaemic (NFHS-5) [2].
- Biofortified varieties, fortified rice, millets in the PDS, ICDS and PM POSHAN, and WASH (water, sanitation and hygiene) together form a multi-layered answer to hidden hunger.
-
Biofortification is cheap over time because the nutrient comes with the seed, and it reaches rural families who eat what they grow.
-
The MSP–procurement link (GS-III):
- Open-ended procurement of rice and wheat at MSP rewards quantity, not nutrition. Farmers get no extra price for biofortified grain.
-
Possible fixes include procuring biofortified varieties for the PDS, ICDS and mid-day meals, supplying good seed, and paying attention to millets such as iron-rich bajra. These also support crop diversification.
-
Limits and complements (GS-III):
- Biofortification adds nutrients but cannot fix poor absorption caused by bad sanitation and disease.
- It is slower to scale than fortification, because it depends on farmers adopting the seed.
- A balanced strategy uses biofortification (long term), fortification (quick coverage through schemes) and dietary diversity together. GM routes need careful regulation.
