27.11.2025 New Podcast Episode: Eingefrorene Zukunft - Saatgutbanken als Antwort auf ökologische Krisen
The fifth episode "Eingefrorene Zukunft - Saatgutbanken als Antwort auf ökologische Krisen" of our podcast series “Mit Sicherheit im Gespräch” is now available. In this episode, we talk to sociologist Leon Wolff about food security, the principle of reversibility, and what all this has to do with cooling technologies.
When we talk about food security, climate change, crop failures, or global supply chains are usually at the center of the discussion. In our conversation, however, sociologist Leon Wolff highlights the problem of loss of plant genetic diversity and explains how industrialized countries are trying to deal with this threat to food security. At the heart of his analysis is an often overlooked security logic: reversibility.
According to this logic, industrialized countries are increasingly trying to achieve food security and biodiversity with the help of seed banks and seed freezing. By creating these “backup copies”, the goal is to make crop varieties available again when needed and reverse the consequences of ecological crises. But this idea, argues Leon Wolff, creates new dependencies, stabilizes old production methods, and thus preserves the ecological crises that raised the questions of food security in the first place.
