The government of Qatar, as I mentioned, has proposed to come and lease Kenya's Tana River delta in order to farm there. What I am not sure of is, has an environmental impact assessment been made to ensure that exploiting this delta for agricultural activities is the best way we can use the delta?We must be concerned about the long-term impact of agricultural activities in the delta.

Nile perch is a fish that was introduced into Lake Victoria. The reason that fish was introduced into Lake Victoria was because it was decided that the people living near the lake needed more proteins than they were getting.

I’m very conscious of the fact that you can’t do it alone. It’s teamwork. When you do it alone you run the risk that when you are no longer there nobody else will do it.

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.

When resources are degraded, we start competing for them, whether it is at the local level in Kenya, where we had tribal clashes over land and water, or at the global level, where we are fighting over water, oil, and minerals. So one way to promote peace is to promote sustainable management and equitable distribution of resources.

No matter who or where we are, or what our capabilities, we are called to do the best we can.

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