For me there are still to many question marks about GM. Just because there has not yet been any direct connection to sickness, does not mean that it does not cause problems, it just means the connection has not yet been found. Genectics is still a very young science and we still know way to little how it really works, though we do a know a lot more than 20 years ago.
BioVision has very interesting projects in Africa which show that there are other and healthier solutions.
Serious droughts: I agree that for natural disasters it won't be a cure. However, I'd argue that if more countries are self-sustainable the impact could likely be decreased and aid would not need to come from overseas.
I'll not argue that GM is the end-all and be-all solution; I consider it just another drop to tip the scale a little further to the positive side. However, the scares about GM are made larger than they in reality are; the tests before large-scale production are quite rigid. The patents, though, are a very annoying obstacle to actual implementation and right now do more harm than help.
