Parts of Africa are very tourist friendly and you can have a perfectly safe, uneventful trip. Other parts are less safe, and these are the parts that might also be visited by professionals such as journalists and reporters who need to visit them to do their jobs. Travelling in these locations requires some knowledge and training so the people know how to keep themselves safe.
Travel safety courses are a recommendation for people travelling in unsafe areas and for most journalists and reports, they are usually a prerequisite before going abroad. These kinds of courses should be paid for by companies sending employees to locations in Africa and, if people are self employed, they should be paid for by them as part of their professional investment and development. Courses teach practical skills and life lessons so people can stay safe while working in countries that have civil or political unrest.
