Success Pathways for Scaling Biofortified Crops

Why It Matters

Accurate scaling and impact measurement of biofortified crops can unlock high‑return nutrition solutions, protecting billions from hidden hunger and driving sustainable agricultural growth.

Key Takeaways

• Biofortified crops can deliver up to $17 social benefit per dollar spent.
• Scaling requires yield‑stable varieties that meet farmers’ profit expectations.
• Accurate adoption metrics are essential; past estimates have vastly overstated reach.
• Multiple pathways—farm consumption, market sales, processed foods—must align with nutrition goals.
• Investing in behavior‑change and digital services can accelerate biofortification uptake.

Summary

The Harvest Plus webinar titled “Success Pathways for Scaling Biofortified Crops” brought together regional experts to discuss how nutrient‑dense staple varieties move from research labs to farmers’ fields. Moderator Brenda Mareri outlined the organization’s two‑pronged model—Harvest Plus’s science engine and Harvest Plus Solutions’ market‑oriented scaling unit—setting the stage for a deep dive into the practical challenges of delivering micronutrient‑rich crops at scale.

Speakers highlighted that more than two billion people suffer from hidden hunger, with rising food‑price volatility pushing households toward cheap, ultra‑processed foods. Biofortification, which enriches staples with iron, zinc or vitamin A through conventional breeding or precision genetics, offers a low‑marginal‑cost solution: over 400 varieties have been released worldwide, delivering an estimated $17 in social benefits for every dollar invested and costing roughly $15‑$20 per disability‑adjusted life year averted.

David Spearman warned that scaling success hinges on accurate data. In Uganda, adoption models overstated orange‑flesh sweet‑potato reach by 14‑fold and high‑iron beans by four‑fold, underscoring the need for rigorous impact measurement. He also mapped four scaling pathways—primary production, on‑farm consumption, semi‑processed market channels, and tertiary income streams—while cautioning against using biofortified crops in unhealthy ultra‑processed snacks.

The discussion concluded that effective scaling demands yield‑stable, nutrition‑rich varieties, robust monitoring systems, and coordinated incentives across seed companies, governments, and consumers. Investing in behavior‑change communication, digital services, and market‑based premiums will be critical to ensure that biofortified crops reach the most vulnerable while preserving their nutritional intent.

Original Description

Globally, more than 2 billion people—one in three—experience vitamin and mineral deficiencies. This “hidden hunger” can lead to premature and preventable death, developmental delays, visual impairment, and lower work performance. More broadly, it can contribute to slower economic growth and intergenerational poverty. Hidden hunger is especially concerning in the Global South, with women, adolescent girls, and young children at greatest risk.

Healthy, diverse diets are the optimal way to address hidden hunger, but biofortification also holds tremendous potential. By breeding staple food crops to increase vitamin and mineral density, biofortification delivers measurable, sustainable improvements to the diets of rural households that grow and consume their own food.

Join IFPRI and its HarvestPlus program, in collaboration with HarvestPlus Solutions, for this seminar on biofortification. Since 2004, HarvestPlus and partners have reached more than 640 million people across 60 countries in the Global South through their efforts to breed, test, and release self-fortifying, high-yielding, and cost-effective crops. This seminar will examine global progress on reducing micronutrient deficiencies through biofortification, including a detailed look at biofortification in Nigeria, Pakistan, and other countries. Speakers will also discuss effective scaling of biofortified crops, with a focus on both the enabling environment and private sector engagement.
