Nice article in World Mag (Today's News, Christian Views) about work being done by Engineers Without Borders. As a case study it works well, but EWB also makes a very good argument for building local ownership of projects.
Towards the end the article gets a little bit weird, as the author takes issue with EWB's characterization of poverty and disease as a cause of “sin”. It seems like an interesting theological question, but doesn't have a lot to do with the issue. On the whole its worth a read.
