Porto Alegre was founded in 1772 by immigrants from the Azores, Portugal. In the late 19th century the city received many immigrants from other parts of the world, particularly Germany, Italy, and Poland. The vast majority of the population is of European descent. The city lies on the eastern bank of the Rio Guaiba (Guaiba Lake), where five rivers converge to form the Lagoa dos Patos (Lagoon of the Ducks), a giant freshwater lagoon navigable by even the largest of ships. This five-river junction has become an important alluvial port as well as a chief industrial and commercial center of Brazil. The port of Porto Alegre is important for transporting local produce. The "capital gaúcha" has a broad-based economy that lays particular emphasis on agriculture and industry. Agricultural production includes produce such as plums, peaches, rice and cassava grown on rural smallholdings. The shoe and leather industries are also important, especially in Novo Hamburgo, in the Metropolitan Region of Porto Alegre. Porto Alegre has a long coastline on the Guaíba Lake, and its topography is punctuated by 40 hills. In the lake, a vast body of water, a maze of islands facing the city creates an archipelago where a unique ecosystem gives shelter to abundant wildlife. The city area concentrates 28% of the native flora of Rio Grande do Sul, with 9,288 species. Among these, there are many trees which are the vestiges of the Atlantic Forest. Fauna are also diversified, specially in the islands and hills. The Portoalegrense environs include many parks, squares and wooded streets. In recent years, Porto Alegre hosted the World Social Forum, an initiative of several non-government organizations. The 9th Assembly of the World Council of Churches was held in Porto Alegre in 2006. |
