One-SEI program

Transforming food systems

Building on years of SEI expertise, this program explores science-based, participatory and equitable pathways that can create a more sustainable, healthier and equitable global food system. We seek to foster rapid, just food system transitions to ensure that nutritious food is available for all, and to minimize harms to planetary health.

Active project

2025–2026

Current food systems play a vital role in feeding the world but face significant challenges in delivering healthy, equitable and sustainable outcomes:

  • Industrial animal agriculture contributes 12–20% of global greenhouse gas emissions and drives biodiversity loss and environmental degradation.  
  • Diet-related diseases, antimicrobial resistance, and zoonotic risks highlight the need for more balanced, nutritious food systems that also promote animal health and welfare.
  • Roughly 2.3 million people remain food insecure, while one-third of food is lost or wasted.

Equitable solutions and just transitions are needed to support farmers, workers, and communities dependent on current food systems.

SEI’s work on food systems transformation spotlights the need to advance both a One Health framework and just transitions within our food systems.
 
We generate evidence on how governance, financing, and regulatory reforms can simultaneously improve human, animal, and environmental health while ensuring that farmers, workers, and communities are supported through structural change.

This includes:

Demonstrating how One Health priorities, including animal health and animal welfare, can be incorporated into food system transitions.

Past events

SEI has been on the frontline of key issues confronting global food systems. Our team brings together expertise on the legal and political dimensions of sustainable development and climate policy; just transitions; alternative proteins; food systems policy; and animal health and welfare. The program also capitalizes on SEI’s geographic reach, tapping experience and networks in Europe and Eastern Europe, Latin America, the UK and the US.
