What stories does food tell about our societies, economies and relationship with the planet?
In the sixth episode of Earth to Research, Lucy Sabin is joined by Madhura Rao, Assistant Professor of Food Systems Governance for Planetary Health at Maastricht University, for a rich and thought-provoking conversation on food systems, waste, circularity and the knowledge traditions that continue to shape more sustainable ways of living.
In “Food for Thought: Systems Thinking & Traditional Knowledge”, the discussion moves far beyond what ends up on our plates. Together, Lucy and Madhura explore the hidden networks, power structures and global connections that shape how food is produced, transported, consumed and discarded — and why addressing today’s ecological crises requires us to think in systems rather than isolated problems.
The episode shines a light on the often-overlooked wisdom embedded within Indigenous and agrarian communities, whose long-standing relationships with land and resources have cultivated practices rooted in reciprocity, restraint and regeneration. Madhura reflects on how many contemporary “green” innovations and circular economy solutions are inspired by these traditions — while also raising urgent questions about ethics, ownership and extractive forms of innovation.
From food waste and circular bioeconomies to corporate accountability and the social life of waste itself, this episode challenges dominant assumptions about sustainability and invites listeners to rethink what we value, what we discard and whose knowledge counts in shaping the future.
Blending personal reflections, critical perspectives and hopeful possibilities, Episode 6 offers an inspiring exploration of how research can help build more connected, equitable and ecologically grounded food systems.
