Hello. 

Instructions says - "It’s not requested to map buildings. Consider a task finished even if buildings are not mapped." It doesnt says that it requested NOT to add buildings. Can you show me where it says not to add buildings?  Or can you add this to instructions? Is it better add building without HOTOSM tags?

About hedges. This part is slightly misleading: 

"Especially in villages, you can also find some barrier=fence or barrier=wall" from https://wiki.openstreetmap.org/wiki/Unite_Maps_Initiative/UN_Mappers/OSM_Features_in_Somalia#Barriers_classification
