Biofortification: The Five Big Challenges

Howarth Bouis, HarvestPlus Director

Guest blog by Tiffany Imes Mickey Leland International Hunger Fellow at the Congressional Hunger Center.

In today's plenary, Howarth Bouis, HarvestPlus Director presented progress made in biofortification, as well as the challenges.

He explained the comparative advantages of biofortification and why this technology that targets the rural poor could be a cost-effective approach to improving nutrition. Bouis also shared the progress that has been made in using crop breeding to improve nutrition. He cited advances in the biofortification of staple crops such as cassava and the use of biofortified foods for school feeding programs in Brazil. He also mentioned advances made in transgenic breeding.

According to Bouis advances in breeding techniques and discoveries of key genes has produced crops with nutrient levels that are high enough to improve human nutrition. Furthermore, Bouis said that “evidence shows that there is no trade-off between high nutrient content and high crop yield.” He highlighted recent findings on the impressive retention of provitamin A (beta-carotene) in maize, which is the most important staple food in much of Africa. Encouraging findings are also emerging from a recent project that introduced orange sweet potato to 24,000 households in Uganda and Mozambique.

Dr. Bouis also shared the constraints he has encountered as biofortification has progressed over the years. He ended his talk by noting the following key challenges faced:

1. Identifying optimal delivery strategies for getting biofortified foods to people
2. Ensuring and measuring the public health impact of biofortification
3. Developing a better understanding of how foods impact human nutrition
4. Getting the agricultural sector to prioritize improving nutrition
5. Getting the nutrition community to prioritize agriculture in order to improve nutrition

The audience particapted in a show of hands to assess which of these they saw as the main priorities. Bouis noted that on the last day of the sympsoium, we would revisit these challenges to see if perceptions had changed over the course of the conference as the latest findings were presented.
