How much farmland does your lunch actually require? And what does a buffet have to do with climate protection?
On July 7, 2025, Berlin’s Weltacker transformed into a vibrant space for learning and discovery: Together with Weltacker Mannheim, we hosted the “Weltacker 2GO” workshop—a mobile educational format that brings our Weltacker vision to life on a small scale.
More than 20 educators, volunteers, and curious participants came together to learn, experiment, and network.
The idea behind Weltacker 2GO is as simple as it is effective: Using easily transportable materials—such as a 5.5 m² tarp, a “surface buffet,” or a CO₂ barometer—you can strike up a conversation with people anywhere. Whether at festivals, in schools, or at the next neighborhood festival: The Weltacker topics can be conveyed anywhere—in a way that’s understandable, vivid, and interactive.
To kick off the training, we took a tour of the 2,000-square-meter Weltacker. Amid the corn, millet, and cotton, we talked about global land justice, food security, and how all of this relates to us.
Then we moved on to the basics: What does Education for Sustainable Development (ESD) actually mean? How does global learning work? And how can we truly inspire people to think and take action?
Then it got hands-on: The participants got to know all the Weltacker 2GO stations—and tried them out for themselves right away. The “land buffet” was particularly popular; it allows people to compare how much farmland a cheese sandwich requires compared to a veggie schnitzel. The CO₂ barometer also sparked exciting discussions: Which foods actually leave which carbon footprints?
The topics included legumes as climate savers, the Planetary Health Diet as a model for the future for 10 billion people, and the question of how we can understand, explain, and collectively reduce food waste.
The training session was not only informative but also creative, open, and warm. For many participants, it was their first time in a field.
To wrap things up, we asked everyone to share three words that came to mind after the workshop. And the answer was clear:
inspiration, motivation, joy—but also “advancing global learning.”
Since 2022, the Weltacker Youth Council has been working with us—an exciting project that brings young people in Berlin together. They all share one goal: a voice in Berlin’s food policy!
