CDA deputy chair David Bayever said: “Forty thousand new prostitutes. As if we do not have enough people of our own, we have to import them to ensure our visitors are entertained.”
Bayever said the agency had been warned by the Durban municipality of the possibility of huge inflows.
Many of the women were likely to be recruited from eastern Europe.
He also warned that the extension of school holidays during the World Cup would put children at risk of being lured into sex work.
“Our youth are going to be on holiday. They are going to be targeted to become prostitutes.”
The CDA is a statutory body that provides advice to the social development department on drug and substance abuse.
Bayever said substance and drug abuse were intertwined with prostitution. Drugs and alcohol were sometimes used to keep people in sex work.
“There’s a correlation between drugs and human trafficking,” he said.
UN Office on Drugs and Crime national project co-ordinator for trafficking Johan Kruger concurred there was a connection between sex work and substance abuse.
He however refrained from endorsing the estimate of 40 000 women entering the country.
“I’m not sure where that comes from.”
During the World Cup in Germany in 2006, many had expected human trafficking to increase.
“It actually decreased because of the preparation of law enforcement,” said Kruger.
He cautioned against too much focus on the World Cup as drugs and human trafficking had been present in South Africa before the event and would continue long after the tourists had left.
“After 2010, illicit organised crime will continue.”
However, South Africa would face an uphill battle in combating trafficking of both drugs and people. Tackling the problem required co-operation on an international level.
“It’s very difficult to combat this crime if is only addressed by one country. SAPA
