A crash course in changing the world.
I think, for my town, Braunschweig/Germany, an information system like Ushahidi is not that necessary. Of course, it would be a "nice thing to have", but as I tried to think about something that is most likely to happen here (natural disaster, food shortages, power outages, political crises, health outbreaks, other social disruptions), I came to the decision that none of it has a high probability of occurring here in the next years. Our region is quite safe concerning natural disasters. Also, things like food shortages are unlikely. Here, we rather find a kind of food wastage. Naturally, you can never say never, but I am pretty sure that there are regions in Germany, but particularly in other parts of the world, which are quite more in need of something like Ushahidi. For example, countries like the Philippines could really need an information system like this as it is on top of the list of countries in the world which are highly threatened by natural disasters like earthquakes, typhoons or tsunamis (http://www.mb.com.ph/node/349474/philippine). If there was a system like Ushahidi, it should track things like the locations of the disasters, maybe the number of injured people/people who died, information about the infrastructure (are the places still accessible via car, plane or whatever?) and other things. These information should be shared with people in the same (threatened) region and should be made accessible to relatives of families who live there, too.
In conclusion, information systems like Ushahidi may be a great help for future crises - no matter on which part of the world.
P.S.: I know I was supposed to write about the town I live in, but since I am half Filipino, I also feel concerned with that country which is much more in need of help than any town in Germany or Germany itself.
