A good note in Gran Combo on the upsurge in social conflicts in Peru. According to the note and also according to the official numbers published by the (literally translated cos it's a good name) "defensor of the people" ombudsman, conflicts and protests have risen threefold in the last two years.
There are other charts on offer at GranCombo too, with one that notes the large percentage of the abovementioned protests generated by environmental and pollution issues.
