About tagging of highways. 
previous mappers used the tag footway. In rural areas like here, you need to tag very small traces as path.
How to measure the width of a trace In Ideditor:
Command Ctr+shift+M  shows the measuring dimensions tab.
After that command, select add line.
Zoom in very far (20 - 25 mtr) so that you have a good view on the shoulders of a road.
Then draw a line between the shoulders.
You can read the value in the measurement tab. (select Metric value)
<2 mtr tag it Path
> 2 mtr tag it unclassified, residential or track depending on the situation. 
 Delete the line after measuring.
See the wiki African highways to decide which tag to be used.
