The Mediterranean Sea is today’s most dangerous border between countries not at war with each other. Just last week, 300 persons departing Libya on four rubber dinghies have gone missing at sea, after drifting for days without food and water. News reports in the past six months have regularly commented upon the rising number of persons disembarking on Italy’s coastline – benefiting from its search and rescue operation Mare Nostrum. Despite the increase in new arrivals from 33,000 to 200,000, the life-saving mission has now been discarded. Italian policy makers believe Mare Nostrum is as responsible for overcrowded reception centres as it is for the rising number of persons risking their lives at sea. But is it truly to blame for the surge? Because more than 50 per cent of arrivals are either Syrian or Eritrean, news commentators have provided some other potential explanations. Some point to the protracted conflict in the Middle East, whilst others highlight the strain on neighbouring Jordan, Lebanon and Iraq in continuing to receive thousands of Syrian refugees. “Poverty in Africa” is mentioned occasionally, and for the better informed, an oppressive military regime and indefinite conscription in Eritrea are to blame. Yet these supposed ‘causes’ of the latest wave in irregular migration to Europe are speculative at most and have in fact been ongoing for many years now. The irregular and mixed movement of persons across borders is arguably the most pressing international issue of our time, second perhaps only to terrorism. Yet the response of nations is too often reactionary and punitive towards individuals making the move, causing policies like Mare Nostrum to be cut short. By pinpointing the multiple ‘Push’ and ‘Pull’ factors at play in the regions concerned it is possible to generate fresh insight on the debate on South- North migration. ‘Push Factors’ For Syrians and Eritreans on the move, the situation at home is the key reason for flight. In Syria, there are immediate threats to life, regardless of which side of the conflict you are on. In Eritrea, an oppressive military regime and a lifeless economy force several thousand to walk across its land borders every month. Ruthless and indiscriminate conscription waves can also augment departures, as can changes in border surveillance, including the reported end to the notorious ‘shoot to kill’ policy.
