Alarmed by the impact of logging, indigenous Peruvians are using satellite mapping to manage their land

The first thing Ramón heard about the deal was the televisions. A number of families from the Asháninka indigenous group had received them from outsiders, in exchange for land. Loggers were interested in the mahogany, oak and tornillo trees that grow to impressive heights in this part of the rainforest around Cutivireni in central Peru.

The loggers had other means of persuasion, besides bribery. They might offer to build a school or a meeting house in exchange for timber. When the work ran over budget, they would demand money – and since the Asháninka had none, they would take more trees to service the debt, according to Adelaida Bustamante, the community treasurer. And if that failed, they used violence. In 2014, four forest defenders from the Asháninka were murdered for their campaign to keep loggers off their land (Ramón asked me not to use his real name).
