In March 2019 FlussLab hosted 4 micro-residencies for interdisciplinary collaborations in the outskirts of Buenos Aires, more precisely in the Delta of Tigre. More than 16 participants then were part of this processes of creation in the natural environment. As the first editions of the micro residencies proposed by @Flusslab, in dialog between Buenos Aires and Berlin, the produced materials were open to the residents of the island, and documented for further iterations.
