As we move forward, you cannot resolve the potential food crisis or shortages without science being part of the solution. Science has to be part of the solution but African governments - and these are decisions for governments, whether they embrace or do not embrace genetically modified food - and for the moment, most African companies do not accept genetically modified seeds.

Each crisis is different, has its own specificities, and we need to look at it critically; look at each one in its own terms.

You have to develop a certain healthy distance to allow you to keep a clear head, to be able to analyse the situation, lead your team, and move forward with them, because there are times if I'm not careful... if you get too involved, it will consume you; it will consume you, and you will not be good to your team; the issues you are dealing with.

On this International Day of Peace, let us all honor those who have suffered from violence. Let us hold in our hearts the ideal of peace.

Sometimes when you take a tough action against one side in the conflict, they see you as part of the conflict and they attack you.

I don't see a situation where one side will win militarily, take over Syria, and there will be peace and quiet, a clean victory.

If one is going to err, one should err on the side of liberty and freedom.
