Tropentag is a scientific conference - surely. Yet each serious research project has a work package dealing with implementation (because funders know it´s good for publicity) - so has Tropentag.

Solidarity in a competing world - a theme directly put into practice at the conference dinner on Tuesday night.

In a role game, participants could emotionally experience competition for limited resources. Solidarity developed - at least amongst the most marginalized at the very end of queues sharing the last bits of food. Meanwhile, waiters were emptying half empty plates into the darkness of Vienna´s sewage system.

But - let´s not forget: this conference is not only about solidarity. It´s also about fair use of resources. But what´s fair, anyway? Yet again: food proved to be the most hands-on- area of implementation. The following images of the Tropentag lunch will not need any further comment.
