Kinshasa vs Río Otún

Informations

Kinshasa (; French: [kinʃasa]; Lingala: Kinsásá), formerly Léopoldville (Dutch: Leopoldstad), is the capital and the largest city of the Democratic Republic of the Congo. The city is situated alongside the Congo River. Once a site of fishing and trading villages, Kinshasa is now a megacity with a population of about 16 million. It faces Brazzaville, the capital of the neighbouring Republic of the Congo, which can be seen in the distance across the wide Congo River, making them the world's second-closest pair of capital cities after Rome and Vatican City. The city of Kinshasa is also one of the DRC's 26 provinces. Because the administrative boundaries of the city-province cover a vast area, over 90 percent of the city-province's land is rural in nature, and the urban area occupies a small but expanding section on the western side.

Kinshasa is Africa's third-largest urban area after Cairo and Lagos. It is also the world's largest Francophone urban area (surpassing Paris in population), with French being the language of government, schools, newspapers, public services, and high-end commerce in the city, while Lingala is used as a lingua franca in the street. Kinshasa hosted the 14th Francophonie Summit in October 2012.Residents of Kinshasa are known as Kinois (in French and sometimes in English) or Kinshasans (English). The indigenous people of the area include the Humbu and Teke.

Informations

The Otún River (Río Otún) is a river in the Risaralda department of Colombia. Its source is Lake Otún, fed by meltwater from Nevado Santa Isabel, and its outlet is the Cauca River. The Otún River passes between the cities of Pereira and Dosquebradas, and is crossed at that point by the César Gaviria Trujillo Viaduct, one of the largest cable-stayed bridges in South America. The Otún River is the only source of drinking water for Pereira and Dosquebradas.

The local water company takes about 1.8 cubic metres per second (64 cu ft/s) from the river at a site known as Nuevo Libaré. Agricultural development in that region has affected the quality of the water from the river, with pig and chicken farms as well as human waste water being major sources of bacteriological contamination.[1]The river passes through several protected zones including the Otún Quimbaya Flora and Fauna Sanctuary.
