Okay, it’s not about billions, but at least about all steerable tasks,
which add up to 30 millionen Euro.

Last year the Berlin borough of Lichtenberg started its pilot
participatory budget. Now it is not a project any more, but a continous
workflow which includes the administration, citizens and politicians.
Based on last years evaluation, the whole process became more
