Since 2007, in the area of a former tree nursery, the international garden in Bonn gives space for social integration. Covering 3,000 m2 the area was turned into an allotment garden with garden plots of approximately 40 m2. The plots are allocated to 25 families from different cultural backgrounds, living in the deprived neighbourhood of Bonn-Dransdorf to support their self-sufficient agricultural practices and foster their social integration (1,10). The aim of the project is to provide gardening families with the option for intercultural exchange and a chance to take roots in a new country. In 2003, the International Garden Bonn project was initiated is implemented by "Wissenschaftsladen Bonn", a community service group who persuaded the city of Bonn to provide the once city property free for this social inclusion project (1).

The project aimed to make the banks of the river Sava a more secure place by setting up illumination poles and thus motivate people to go there also by installing potable water fountains. The project includes environmental friendly illumination of both sides of the river Sava, development of 6 water pipes and toilets and renovation of the pedestrian and bike paths (4 sq km). The project in the second phase will also include additional illumination and water stations up to Jankomirski Bridge (in total 16 km, on both sides of the river Sava) (Ref 1).
The locals use the area for running, dog walking and for relaxation. Previously the place didn't have lights which made it unsafe during the night. The Mayor promised the citizens to return the river as well as an emphasis on the bridges that "conect, rather than separate" (Ref 1, 2, 3, 4).
