To analyse the "virginity" of an area I created a binary raster with

1 = human infrastructure (road, housing, ...)
0 = no human infratructure (forest, agriculture, ...)

I would no like to calculate the distance from each cell (especially the 0-cells) to the nearest cell with value 1.

How? I use QGIS 2.18.
