You don’t need a dictionary to know what “Wildplassen” means.
If they catch you doing it in Ghent, you’ll be fined sixty Euros. As you can see from the sign, the rule applies equally to both sexes.
This is quite a stiff penalty, considering that the fine for the same offense in Paris is only thirty-five Euros.

Poster on a Paris garbage truck, 2012
This poster on a Paris garbage truck shows, on the left, a drink of some sort with a price tag of 2.80 Euros. On the right is a place where someone has urinated on a wall, with a price tag of 35 Euros. The slogan reads; “Paris met les pollueurs à l’amende.” Which means: “Paris fines polluters.” And at the bottom it says: “400 sanisettes gratuites à Paris.” Which means: “400 free sanitary cubicles in Paris.“
Both my photos in this post are from 2012. I revised the text in 2019.

I have no idea what the fine for this is in London or even if there is one!
Of course the best way to prevent wildplassen is widely available public restrooms. The public restrooms in Albania were certainly few and far between, but they did have these signs: https://picnicatthecathedral.files.wordpress.com/2016/10/punkrock.jpg
Even thus sometimes folks do it in the wild here in my area we have public bath in every town or village. I think the sign cost more than the 60€ lol!!!
I hope that Ghent has more public conveniences than we do then Don
