The International Maritime Bureau attributed the sharp drop to "pre-emptive and disruptive counter piracy tactics" by international navies patrolling in seas off Somalia as well as increased vigilance by ships including hiring private armed personnel on board.While I'm sure that the navies of NATO et al like to think they have had some impact, the real change in the last year or 2 is the embarkation of armed mercenaries - security forces - on ships in the worst areas.
The bureau said the decline in Somali piracy was partially offset by intensified and violent attacks in the Gulf of Guinea off western Africa, where 32 cases including five hijackings were reported, up from 25 in the first half last year. Nigeria reported 17 cases, nearly triple the number from a year ago. Togo reported five attacks including the hijacking of a tanker, up from no incidents in the same time last year, it said.Several countries in West Africa are getting aid to beef up their navies, including Ghana, which picked up a couple of surplus German fast-attack-craft.
Ghana has been reviewing measures to safeguard its waters, most importantly to protect our oil installations from pirate attacks. Piracy in the Gulf of Guinea is not on the scale of that off Somalia, but analysts say an increase in scope and number of attacks in a region ill-equipped to counter the threat could affect shipping and investment.Sailing on the account, is an ancient (if not exactly time-honored) tradition. Keeping it in check means military might. That's what worked in the 1800s, and that is what is working (finally) in East Africa.
