BBC - BBC World Service Programmes - Discovery, Feeding The World, Episode 2: "A drought resistant maize is needed urgently. Sue Broom travels to Kenya and Mozambique to investigate a new research project that is combining conventional crop breeding with genetically modified crops."

From what I have been reading and listening to about permaculture things need to change to really boost food production.

The problem isn't the maize or the water or even the land but how the land is shaped. From the pictures I bet the water they do get runs off pretty quickly. That is what really needs to stop or rather slow down.
