Tonight, a special edition from Kenya. Elephants pose a huge problem for
Kenyan farmers: they feast on fields of maize and have worked out howto get round electric fences.
Shahnaz Pakravan and Craig Doyle meet the inventor of a fence that can outwitthe cleverest elephant. Also, the woman who saved the country's banana industry, and a new contraceptive vaccine for baboons that could eventually work for humans, perhaps replacing the pill. Presented by Howard Stableford and Vivienne Parry.
Producer Jonathan Renouf ; Editor Edward Briffa
