The state of people on the brink of starvation is shocking, there are so many very hungry people. the first thing they need is water, so, seeing as how somalia and yemen are right next to the sea, a desalination plant could help. this would cost a fraction of bottled water to reach them. Or, they could observe it is spring there, so rain fall will be on the way. alternatively, they could create water vapour by observing that a jet travelling at the speed of sound creates water, so, sound could generate the vapour required by being upped in pitch - take a huge speaker and put it 'on it's back.' then, put a lot of pots on top of the speaker, and then do the right things to create sound waves that travel fast, and then get the water.
