The weltacker presented on IGA 2017 allows for a different kind of learning experience when talking about water usage in food production (find out more about our visit to IGA).
It’s 2000m² let you experience the diversity of agriculture around the world. We were able to talk to one of the representatives of weltacker who explained the concept and gave us a tour of the global field.
You can find the website of weltacker with a lot of information oin agriculture here: https://www.2000m2.eu/
Later we had the opportunity to calculate the water footprint and the landuse of diffent meals via a per-built worksheet. weltacker thankfully made it possible for us to share these worksheets with you. You can download them here:
On Tuesday, as a part of glocal education, we attended the International Garden Exhibition (IGA) in Berlin Marzahn-Hellersdorf for a variety of non-fromal educational activities.
When entering IGA we were greeted by a representative of weltacker. She explained the concept underlying the weltacker:
It is an area of 2000m² which is exactly as much land as every living human should be able to get his_her food from when dividing the amount of land which is used for agriculture by the number of humans living at present. The average european is using up to 4000m² of land for their food, according to some calculations. The aim of weltacker is to draw attention to this fact through educational programs and meals that were grown on just theses 2000m².

One of the practices the weltacker team tries to visualize the land used in agriculture is the following: The group is given a rope and will then try to lay it down in such a way, that the enclosed area equals the area necessary for a specific meal, let’s say a pizza. We had some really interesting insights and got a feeling for just how much land is used in agriculture.
This part of the weltacker is basically the sollution to the answers raised beforehand. Here the visitors can find out how much land is used for a specific meal and which plants are needed for it. The pizza plot obviously grows some wheat, tomatoes and depending on your topic some vegetables, too.
Here we see the roots of an agriculturally used plant. It is quite impressive how far down the roots reach. You can really see how much plants value water. And the mechanisms used to transport the groudwater through the plant to be used in the leaves during photsynthesis is fascinating.

Towards the end of our visit we had the oportunity to calculate the land- and waterfootprint of different meals. We found out how much water is used to produce a Hamburger compared to the waterusage of a Veggieburger. And of course we had to calculate the waterfootprint of a Schnitzel. You can find the worksheets we were using here: https://obuk-ev.org/watertraining/2017/11/22/weltacker-the-global-field/
All in all our visit to the weltacker was a really interesting and informative part of our training program.
