Iron and zinc based biofortified potatoes: Scaling strategies to fight against anemia in the Andes

Iron and zinc deficiency remain major public health challenges in the Andean region, particularly affecting young children and women of reproductive age. This document presents the scaling strategy for iron- and zinc-biofortified potatoes (PBH) developed by the International Potato Center (CIP) as a sustainable, food-based approach to reduce anemia and improve nutrition in Peru. The innovation is based on conventionally bred potato varieties with increased bioavailable iron, resistance to late blight, and strong cultural acceptance. The strategy integrates horizontal, vertical, and deep scaling pathways, combining local seed systems, market integration, public policies, and nutrition education. It emphasizes multi-stakeholder partnerships, inclusive value chains, and a gender-transformative approach that promotes the participation and leadership of women and youth. Overall, the strategy demonstrates the potential of biofortified potatoes to strengthen resilient agrifood systems, improve nutrition and food security, and generate sustainable social and economic impacts in the Andes.
