ABU DHABI, May 14 (AFP) – Navies attempting to halt the reign of terror at sea by Somali pirates can only treat the symptoms, naval leaders say, pointing out that the real solution lies in stability on land in Somalia.

Anti-piracy efforts ''will not actually resolve the base problem of why piracy is occurring ... That solution lies in the stabilization'' of Somalia, Commodore Bob Tarrant, director of Britain's Royal Navy staff, told AFP at the Indian Ocean Naval Symposium (IONS) in Abu Dhabi.

''The symptoms (piracy) we're seeing now off Somalia, in the Gulf of Aden, are clearly an outcome of what's going on the ground'' there, said Australia's navy chief, Vice Admiral Russell Crane.

''As sailors, we're really just treating the symptoms,'' not the root of the problem.

Nonetheless, naval efforts against Somali pirates, which were stepped up between late 2008 and early 2009 in response to a spike in attacks along one of the world's busiest shipping routes, must be continued, IONS participants said.

''At this stage, there's no other option'' to combating pirates at sea, Tarrant said.

Imagine ''a situation where it wasn't done, where piracy was allowed to run riot and be rampant,'' he said.

''You can imagine what that would do to the markets in certain commodities and the price of (shipping) insurance, and to people's confidence in their own governments.''

Crane agreed, saying the ''symptom has to be treated – you can't just turn your back and ignore it. You've got to deal with it.''

Various anti-piracy task forces have been operating off the Horn of Africa for more than a year now, but attacks are continuing.

Somali pirates attempted 217 attacks over the course of 2009, according to the International Maritime Bureau, which monitors maritime crime.

There were another 35 attempts between January and March this year, IMB said, a decline of 27 from the same period last year.

IMB director Pottengal Mukundan has said he fears there will be even more hijackings this year than in the past, noting that pirates are now operating over a wider area than they have before.

In the end, though, Crane said ''I have every confidence that, given the united global reaction to (piracy), and the number of countries that have put ships in there, that in the not-too-distant future, we'll have (it) under control.''

Navies engaged in anti-piracy efforts face other difficulties, in addition to combating an ultimately land-based problem at sea.

''There's a vast area to patrol,'' Tarrant said. ''The pirates are an audacious bunch, and we've seen pirate attacks taking place as much as one thousand miles (1,600 kilometres) from the coast of Somalia.''

''Despite all these navies, and I think there are some 28 nations working together in this effort, you cannot possibly patrol and protect all the time.''

There are a plethora of naval forces – including the US-led Combined Maritime Forces, an EU force, one from NATO, and independent deployments from Russia, China, India, Iran, and other nations – operating against the pirates.

The various forces coordinate with each other, but do not operate under a unified command structure. This means they are not as effective as they might be, two admirals said.

''I think we could do it a lot better if we came together as a single group of international navies,'' said Crane.
