IFPRI @ Micronutrient Forum: 7th Global Conference

Nutrition at the Frontiers of a Changing Environment
Hybrid Event

Kempinski Hotel Gold Coast City

Accra, Ghana

September 28 to October 1, 2026

  • 9:00 – 5:30 pm (Africa/Accra)
  • 5:00 – 1:30 pm (US/Eastern)
  • 2:30 – 11:00 pm (Asia/Kolkata)

Micronutrient deficiencies are one of the world’s most widespread health crises, impacting one in two children and two in three women globally. Inadequate intake of essential vitamins and minerals can have lasting consequences on survival, health, and well-being that echo across generations and limit economic growth. As climate change and other crises disrupt food systems and livelihoods, addressing micronutrient deficiencies has never been more urgent.

The Micronutrient Forum’s 7th Global Conference, themed “Nutrition at the Frontiers of a Changing Environment,” will take place in Accra, Ghana, and online, from September 28 to October 1, 2026. This hybrid conference will convene the global nutrition community to build knowledge, strengthen advocacy, and sustain nutrition progress in a changing world.

The program examines evidence, policy, and innovation across nutrition, food systems, climate, and development, exploring how emerging technologies, advanced data, and new partnership models can drive sustainable, equitable impact. Plenary sessions, oral presentations, and research posters are organized around three tracks: (1) biology, data, and efficacy of interventions; (2) program implementation and effectiveness; and (3) designing an enabling environment. IFPRI researchers will be actively involved in the conference, from leading thematic tracks to presenting research findings from around the world.
