Is there a continuing role for

biofortification to address micronutrient

deficiencies? An agriculture-nutrition tool to

identify contexts in which biofortification has

an important role to play.

Relative potential of interventions

Supplementation has a parallel role to play to meet the needs of

specific vulnerable populations, therefore we do not consider it further

Fortification can cost-effectively reach populations that consume

fortification vehicles

Biofortification has relative advantage reaching those that cannot

access fortified foods, and/or have limited access to nutrient rich foods

Interventions that improve quality and diversity of diets should be a

long-run strategy as they address the underlying cause of deficiency

All this means that context matters in choosing the right mix of fortification, biofortification and dietary diversity interventions…

• There is a Fortification Assessment Coverage Toolkit (FACT) that helps determine the

potential for fortification

• And a Biofortification Prioritization Index (BPI) that helps determine the potential for

biofortification

• Harvest plus’s portfolio analysis work has considered several combinations of biofortification and

fortification interventions to assess micronutrient deficiency, but using prospective analysis

• B-FACT considers the potential for the two side by side in a snapshot similar to FACT

Biofortification-Fortification Assessment

Coverage Toolkit-B-FACT tool

• Considers fortification coverage alongside

biofortification, with information on consumption of

micronutrient rich foods

• Allows nutrition and agriculture teams to plan jointly

supporting multi-sectoral approach to addressing

micronutrient deficiency

• Supplementation is not included since it must continue in

parallel for severely deficient populations

Using qualitative and quantitative data B-FACT

assesses…

• Percentage of population that consumes

– Fortifiable or fortified products– Micronutrient rich foods– Crops that they grow themselves, or source locally

• Percentage of population that has low dietary diversity, no access to fortifiable products but who consume crops grown locally --- biofortification has greatest potential to reach these populations

Biofortification’s

potential for scale in

Eastern Uttar

Pradesh, India

Page 9: Is there a continuing role for biofortification to address ... Narayan... · fortification Consumed micronutrient rich product Among 96 % of rural households with no access to zinc

India’s context: Eastern Uttar Pradesh Region

Deficiencies

Vitamin A, iron

and zinc

deficiencies

are a public

health problem

Biofortifiable crops

• Zinc wheat and rice

• Iron pearl millet

• Lentils

Fortification vehicles

(voluntary)

• Wheat flours, rice (iron, folic acid,

vitamin B12)

• Oil and milk (vitamin A, vitamin D)

• Salt (iodine, iron)

Mandatory for school meals

and public distribution

systems beginning 2019

Double-fortified salt is not

preferred by households

Dietary diversity

• Poor access to iron and

zinc rich foods

• Better access to Vitamin A

rich foods (mangoes,

papaya, green leafy

vegetables)

Among 96 % of rural households with no access to zinc fortified products or zinc-rich foods:• Rice bio-fortified with zinc would reach 84% of rural households• Wheat biofortified with zinc would reach 20% of rural households

Key recommendations for addressing micronutrient

deficiencies:

• Mix of micronutrient interventions needed; context is key

• The potential for biofortification’s impact is greater in scaling up iron- and

zinc-biofortified crops

• When fortification standards are voluntary, there is a greater role for

biofortification since behavior change constraints exists even for fortification

• Large gaps exists in access to micronutrient rich foods which need to be

addressed
