Hello. Thanks for mapping on this project,
Please use the tag highway=path rather than footway. See this paragraph on the wiki highways east africa.  Quote:
Path 	highway=path 			Paths are usually impassable for motorised vehicles. (However, African motorcyclists can sometimes do the most improbable stunts.) In order to mark a path as appropriate for cycling, add bicycle=yes. Never use path to mark an unpaved or unsealed road in built-up residential areas: Such roads should be tagged according to the local conventions (usually highway=residential if passable by vehicles and pedestrians, or highway=footway for pedestrian only where they can sometimes be separated from another parallel highway for vehicles) 
btw. A path, as well as track, are by default unpaved. No need to add that tag,
Best regards
