 Several non-governmental organizations have expressed concern that the project was approved with atypically little effort on Environmental Impact Studies.Concerns are both environmental (such as deforestation, illegal hunting and fishing, soil erosion, loss of biodiversity, or loss of ecotourism value), and social (such as harm to indigenous populations, illegal crops, drug and arms trafficking, "slaving underemployment", or prostitution).There is an intention to build another route between Paita and Yurimaguas, both in Peru, to give river access to the Amazon and Brazil.
