As a primer, some excellent recent articles can be found here, here and here.
There's more on Driessen's website plus these links to Africa Fighting Malaria and the Malaria Foundation International.

Bottom line is this: Africa has a malaria epidemic that kills millions every year, especially young children. Those on the front line of the fight against malaria want to eradicate the disease the way we did: cheaply and effectively. Inside spraying of homes using DDT will accomplish this.

The only barrier is one induced and popularized by Western environmentalists: the ecomyth that DDT and other pesticides cause cancer in humans and denigrate the natural environment. The ecomyth as eco-imperialism.
