The population is rising, weather patterns are changing - does that mean the word is going to struggle to feed itself? Or, is there actually already more than enough food to go round? Is the real problem that so many people around the world can't afford food?

We hear from two titans of the world food industry - Justin King, the boss of one of Britain's biggest supermarket chains, Tesco - and Jim Rogers, an investor with huge stakes in agriculture around the world. We also speak to agricultural ecologist, Sir Gordon Conway, the author of One Billion Hungry: Can We Feed the World?, and a budding entrepreneur from Nigeria, Affi Williams, who runs a dried fruit business in Lagos.
