The Arab spring reminds me a bit of the decolonisation process where one country gets independence and everybody else wants it. How about us, when do we get it, when do we make our move? And you have a situation where someone has been in power for decades, where the integrity of elections, democracy and security have really not been debated or discussed and most people suspect that elections are rigged and that the democratic rotation that elections are supposed to ensure doesn't really happen. And when this goes on for a while you are sitting on a powder keg.

As we move forward, you cannot resolve the potential food crisis or shortages without science being part of the solution.
