Puerto Nariño is an indigenous town located deep in the Amazon at the clean-watered lake, Tarapoto, and the mighty and murky Amazon River. The inhabitants are intimately connected with the environment around them; the forest, river, and lake provide everything from water to food, materials, and medicine. But the environment is endangered by a multitude of threats including illegal gold mining, deforestation, and climate change. The town is, however, also a case of adaptation. Each year, the river rises more than 10 meters, so the locals have long ago learned to build houses on stilts and floating logs.
