Our recent podcast "The Cobra Effect" explored the unintended consequences of bounty programs. The episode was inspired by a visit to South Africa not long ago, where I was told about a rat problem in the Johannesburg township of Alexandra. For whatever reason, that story didn't make the episode. But now the Guardian comes to the rescue, reporting on Alex's efforts to fight off the rats by offering a cellphone for every 60 rats caught:
[C]ity officials have distributed cages and the mobile phone company 8ta has sponsored the volunteer ratcatchers.
Resident Joseph Mothapo says he has won two phones and plans to get one for each member of his family. "It's easy," he told South Africa's Mail & Guardian newspaper, wielding a large cage containing rats. "You put your leftover food inside and the rats climb in, getting caught as the trap door closes."
But there were signs that the P.R. stunt could backfire, as animals rights activists criticised the initiative on social networks.
Will this lead to rat farming or other shenanigans? The Guardian reports that owls have also been distributed to help hunt down the rats.
