In this Oct. 29, 2015 photo, students Atmer Augusto, right, and David Cajos, from the Yarina Industrial Technical secondary school, pose for a portrait with a Peruvian flag after rehearsing for a parade that will mark the anniversary of their village, Puerto Libre, in the municipality of Ciudad Constitucion in Peru’s Amazon where many farmers grow coca, the plant used to make cocaine. Juan Manuel Torres, a drug policy expert with the nonprofit Center for Research into Drugs and Human Rights, advocates a more integrated approach to coaxing coca farmers to plant different crops : low-interest loans and a phased eradication that would let farmers keep some coca while introducing new crops.
