"Certainly, one of the major challenges that the world will face in my lifetime is that of development. Perhaps it is time to develop a new model, or at least re-assess the models that we have been using."
A friend of a friend is currently living in the province of Enga in Papua New Guinea and has been blogging for some time now. Both of these guys offer some opinions on the development models used for developing nations. What they both recognize is the fallibility of humanity in underdeveloped places where resources are stolen from those who need it.
Although both are not geographers, check out both of their blogs. It should provide you with some aspect of the things good people are doing in the world today and extend your geographic knowledge of lesser known places.
