How can humanity feed a growing global population without undermining the ecological systems that sustain life? The EAT-Lancet Report offers a scientifically grounded vision for healthy diets within planetary boundaries. Researchers from the Environment and Climate Research Hub (ECH) reflect on its relevance - from biodiversity and plant resilience to pollution, food systems, and human behaviour.

The EAT-Lancet report presents a bold vision for sustainable nutrition. However, changing people's eating habits requires more than that: In this interview, environmental psychologist Sabine Pahl explains how culture, identity, and habits influence food choices, and why insights from the social and behavioural sciences are essential to turn planetary health goals into real-world action.

Alexandra Brausmann, environmental economist at the University of Vienna, examines the EAT-Lancet Report through an economic lens, focusing on what it means for policy, prices, and incentives. She discusses how shifts in diets could reshape markets and inequalities - and why reflecting the true environmental and health costs of food in prices and policy decisions is essential for creating sustainable and politically viable food systems.

We speak with Wolfram Weckwerth, Head of the Molecular Systems Biology lab and the Vienna Metabolomics Center at the University of Vienna, about the EAT-Lancet Report from a biological systems perspective. He reflects on plant diversity, stress resilience, and the limits of yield-driven agriculture - and introduces AIPN, a new research platform that brings together metabolomics, microbiome research, psychology, and AI to translate planetary health diets into data-driven, personalised strategies

Thilo Hofmann, environmental scientist and co-director of the Environment and Climate Research Hub at the University of Vienna, reflects on the EAT-Lancet Report. Drawing on his work on soils, water systems, and persistent contaminants like microplastics and PFAS, he highlights how pollutants can undermine nutrient cycles, ecosystem health, and the long-term sustainability of food production - and why interdisciplinary research is essential.

Franz Essl, ECH member, ecologist and biodiversity researcher at the University of Vienna, discusses the EAT-Lancet Report with the ECH Editorial Team, focusing on how food systems contribute to biodiversity loss and climate change. He argues that protecting intact ecosystems is fundamental to long-term food security - and that only interdisciplinary research can address the complexity of global food system transformation.
