Roy Pinedo stretches his hand out from a window of his house after a powerful flood swept through the city of Puerto Maldonado, the capital of the Madre de Dios Region. Since 1962, the Madre de Dios and the Tambopata rivers have spilled over their banks and flooded dozens of nearby cities. Thousands of people and their houses were damaged by the flood in 2014. Roy Pinedo sneaked back to his house to retrieve valuables. But he was able to save very little.
