Makeshift wooden houses, some provided by local authorities, some built by its residents, host people displaced by the flooding Paraguay River. The flooding has been caused by heavy rainfall, due to the El Nino phenomenon, and massive deforestation for agribusiness and cattle ranching in northern regions. Over 90,000 people have fled the deluge and are living in makeshift wooden houses around the city. The flooded areas, beside the river, were historically populated by rural poor newcomers to the city.
