In his lecture at the Nobel Talks series, Biovision’s Foundation Board President Hans Rudolf Herren explains why agroecology is a key lever for creating a fair and sustainable food system and what actions need to be taken politically and socially.

Speaking as part of the Nobel Talks at Expo 2025 in Osaka, Hans R. Herren outlines the major challenges facing global food systems and emphasizes the urgent need for transformation.

He illustrates how industrial agriculture contributes to hunger, environmental degradation and social inequality and why agroecological approaches offer a viable alternative. His talk combines scientific insight with clear political recommendations.

The video is part of the virtual series “Nobel Talks – Designing Progress Together”, organized by Metapeace and the University of Zurich within the Swiss Pavilion at Expo Osaka.

Making agroecology visible: A Biovision approach

Biovision is committed to improving the political framework conditions for agroecology. A key lever: the visibility of enterprises that successfully implement agroecology. These enterprises demonstrate that economic success and social commitment can go hand in hand, providing compelling evidence in favour of sustainable agricultural policies. In the video, we use the example of an award ceremony in Kigali, Rwanda, to demonstrate exactly how we shine the spotlight on these enterprises.
