First of all, farmers should work with universities and research institutions in the country, and hopefully with the government.

Disempowerment - whether defined in terms of a lack of self-confidence , apathy, fear, or an inability to take charge of one's own life - is perhaps the most unrecognised problem in Africa today.

I was particularly talking with respect to aid, because that to me is one area that can make people so dependent, and unfortunately, that dependency starts with the government.

There are certain areas where foreign investors can help the local people to generate wealth, and improve their quality of life. Some companies, for example, Del Monte, which produces pineapples in Kenya, pay a huge amount of taxes, I am sure, to the Kenyan government, and they do create jobs for thousands of locals.

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.

Using trees as a symbol of peace is in keeping with a widespread African tradition. For example, the elders of the Kikuyu carried a staff from the thigi tree that, when placed between two disputing sides, caused them to stop fighting and seek reconciliation. Many communities in Africa have these traditions.

Monsanto will not come empty-handed. Monsanto will come with a big bag of money. And because these governments are poor, when they are shown money for their research institutions, for their universities, for their professors, they are very quick to say yes, and I can tell you that when Monsanto came to Kenya, they were able to be given permission to do research in one of our research institutions, and yet there was not a single law to control such research.
