I think [GMO] is one area where the is a need for legal regulations to make sure that companies - because at the moment, companies are the ones that have this technology - will not use this technology in a way that could adversely affect the people.

For example, they have land. The government of Qatar wants to lease the Tana River delta, which is in Kenya, from the Kenyan government, so that they can produce food there. People in Kenya need food. We have people who have studied agriculture. Why is it that if we really need food, we cannot go into the delta and develop our own food?

I'm sure the government of Qatar is not coming in to grow food for the people of Kenya; it's coming to grow food to sell. If it can also sell to the people of Kenya, well, then good. I think that the moves can be helpful, but I think that the history that Africa knows, as I say in my book, has been a history of exploitation.

You cannot blame the mismanagement of the economy or the fact that we have not invested adequately in education in order to give our people the knowledge, the skills and the technology that they need in order to be able to use the resources that Africa has to gain wealth

In Kenya, one of our biggest exports is coffee. Where do you grow coffee? You grow coffee in the land. To be able to grow coffee you need rain, you need special kinds of soils that are found on hillsides, and that means you have to protect that land from soil erosion so you don't lose the soil. You also want to make sure that when the rains come you're going to be able to hold that water and have it go into the ground so that the streams and the rivers keep flowing and the ground is relatively humid for these plants.

Some say that AIDS came from the monkeys, and I doubt that because we have been living with monkeys from time immemorial, others say it was a curse from God, but I say it cannot be that.

As a scientist I cannot say we don't want to hear anything about GMOs, because these are advances in science. But I think its also important, especially when you are dealing with food, to be cautious.
