We found a sixfold increase in fires in protected areas across biodiversity hotspots following guerrilla demobilization in Colombia, and a 52% increase in the probability of per-pixel deforestation within parks for 2018. Peace requires urgent shifts to include real-time forest monitoring, expand programmes to pay for ecosystem services at the frontier, integrate demobilized armed groups as staff of protected areas, and establish a domestic market for frontier deforestation permits %U https://www.nature.com/articles/s41559-018-0727-8
