If Africa is left behind, she is going to continue pumping greenhouse gases into the atmosphere, especially carbon. She's going to continue logging the forests, she's going to continue burning charcoal, she is going to continue practicing agricultural activities that destroy the environment, and sooner or later Africa's problem will become a global problem.

There is no reason why a company like Monsanto, for example, that is pushing GMOs, cannot go to Kenya, partner with the university, partner with the research institutions, and try to promote - in a responsible way - advanced techniques to help farmers. But this should be done in such a way that the farmers' livelihoods are not undermined because the government is irresponsible or careless, or because it is compromised.

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.

Women are responsible for their children, they cannot sit back, waste time and see them starve.

The issue of climate change, it really does bring home the fact that we are on one planet, and that some of the impact of what human beings do in one corner of the world is going to affect people in a distant corner of the world. So we may still feel very far from each other, but we are really very close to each other because of the changes we have made with travel and technology and especially the information technology.

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.

Unfortunately, the issues of climate change, unlike many other issues, are very subtle because the changes we observe are very, very subtle.
