By focusing on the importance of education for a self-determined life and the peace-building effect of encounters, real changes have been achieved. Such commitment is the basis for coexistence, cohesion and democracy. "You are a world bridge builder," said Josef.

Andrea Alleker-Fendel founded PROBONO Schulpartnerschaften für Eine Welt e. V. in 2004 with the vision of realizing the idea of One World through the spread of school partnerships in North and South. For the political scientist and mother of three children, this step was the answer to her question of how development can be promoted in the South and how, at the same time, perceptions and behavior in the North can be sustainably changed. 

Since then, PROBONO has built numerous classrooms, dormitories and laboratories, provided support with books and teaching materials and helped to improve living and learning conditions at dozens of schools in Tanzania, Uganda and Kenya by building wells and solar panels. However, the focus on strengthening the capacities and skills of teachers and pupils at African schools also became increasingly important. This resulted in programs for teacher training, reading promotion, child protection and improving the professional opportunities of graduates.

What is special about PROBONO's work is that it is integrated into school partnerships between North and South. At the heart of this is social and global learning in exchanges between the partner schools - be it in letters, in joint learning in digital project weeks or in work camps during visits. In addition, German partner schools repeatedly support the equipment and construction projects in East Africa.

For 20 years now, PROBONO has been helping to realize what Andrea Alleker-Fendel had in mind when it was founded: "To create a world in which people from different cultures learn from each other, fight poverty together and take joint responsibility for the future of the planet."

In 2013, the Anna-Schmidt School in Frankfurt won the first price in the nationwide competition held by the organisation "Gemeinsam für Afrika" (United for Africa) for their project "Tuishi Pamoja – Friendship in the Savannah". The musical production was a joint project carried out by primary school students from the Montessori School in Frankfurt who performed the musical on stage and the students from their partner school in Kenya, the Ilmissigiyio Primary School, who were encouraged and supported by PROBONO to create a beautiful stage setting for the production.

By working together on the project, the children of both partner schools developed a close relationship, just like the zebra and the giraffe who in the musical become good friends despite their many differences. The children were thrilled that they were able to work together and carry out the project even though they were living on different continents.

In June 2010 the Albert-Schweitzer Secondary School in Tuebingen was awarded the prize "Eine-Welt-Preis Baden Württemberg" for the German/ Ugandan production of the children's musical "Mtoto Boga". The project, a joint production by the school in Tuebingen and the St. Michaels' Vocational School in Butende, Uganda, was initiated by PROBONO. The rehearsals were carried out separately at the two schools and the musical was then performed together in Tuebingen during a visit by the young students from Uganda at their German partner school.
