I have just spent an unforgettable week working in a congolese refugee camp. It holds 19000 people and has been there for 15 years - but it looks anything but temporary. The houses are tiny shelters made from bamboo and mud, crammed together on the very top of the most inhospitable and unwelcoming hill in BYumba. The camp is sited on the land which is of least use to rwandans and it is a desolate place, yet beautiful too as it looks down on tops of green mountains from all sides..
We were trying to train teachers in how to teach maths in english, but as the teachers are congolese refugees they speak excellent french and little english.
