The issue of carbon is one area where we really need to work together and if people don't have the technology they need, that technology needs to be made available and affordable.

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

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.

Sometimes we become bound by other people's thoughts because we are not sure about ourselves.

After Hurricane Katrina, many people said that the levees were not as effective as the natural vegetation that had been removed at the coast. So that means as we develop these seaside land masses, we need to have enough knowledge to not regret in the future. We know that the US government is literally buying these lands back to allow them to be rehabilitated.

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 can't reduce poverty in a vacuum. You are doing it in an environment.
