Yes it is a global issue. Eg the UN are always advocating to countries to have safe routes for asylum. Every stretch of water in the world has the same problem of small boats bringing a mix of people who are refugees fleeing war and want to seek safety, and economic migrants fleeing poverty who are seeking jobs and a better life.
A mix of people on the same boats, exploited by the same trafficking and smuggling gangs as States don’t have any formal and legal channels open to them.
The answer is legal routes for people fleeing war, conflict and persecution to reach safety. And legal routes for people wanting to migrate for better economic opportunities to move as a migrant worker.
The UN and many international organisations have serious recommendations and models for both. The problem is that countries across the world, from Indonesia to Australia, from Iran to Oman, from Saudi to South Africa, from Greece and Spain and the UK to Canada and the US, from Dominican Republic to Brazil to Argentina … these countries don’t want to let them in.
So what are we do to about people moving? Human mobility is a thing. For different motivations and needs. But the tensions with States not wanting to cooperate are getting worse. Something has to give.
