The BBC reports that Tanzania has recently granted citizenship to 162,000 Burundian refugees who have been living in Tanzania for years. Many are Hutus who fled Tutsi violence in Burundi during the 1990's and have since integrated into villages and the fabric of Tanzanian society. This is a precedent for its scale as far as I can tell and seems to be a much better outcome then deporting them en masse, as was discussed in 2008.
Mother Jones has created an interactive map demonstrating what they call the "celebrity recolonization of Africa." Pop personalities are vying to claim their own territorial niche of the continent on which to bestow charity (or at least a 'fact-finding' trip). Is celebrity advocation really helpful or does it just perpetuate erroneous stereotypes and false us-them dichotomies? Somehow this seems to be another incarnation of 'white-man's guilt' over an exploitative global system--give token charity rather than make structural changes that will inconvenience the economic hegemony.
