If an US or UK tour company hires an air operator to fly its clients to safari lodges or anywhere else it is “duty of care” to make sure that pilots are trained to recognized standards and aircraft maintained likewise. In the same way safari guides and even kitchen staff have to be trained, injuring tourists causes a great deal of paperwork and cost.
If a tourist hires a local tour operator it is his own responsibility, there are many incidents involving local unregulated operators not particularly aviation, river tours and canoes quite often.
If your goal is a commercial pilot the only way is FAA or EASA, currently there is a large surplus of qualified pilots, it’s a long haul for local guys.
