Use Image -> Zealous Crop which removes unused space from edges and middle of the image.
otherwise it is: select -> cut -> paste -> move -> anchor -> autocrop
The first advise worked just fine for me. I have one more question for the second option you gave. Is there a way to tell gimp to snap the upper and the lower part together when moving it. For example if I enable "snap to canvas edges" and I use the selection tool, it helps me to select exactly the edges of my canvas. In this example it's not required that the upper and the lower part match exactly if you merge them, but I can think of examples where you'd want not want to move the parts by hand and then auto crop, but rather merge the lower and upper part exactly and then remove the transparent part.
And thank you already for your help
