Bogotá savanna

The Bogotá savanna is a montane savanna, located in the southwestern part of the Altiplano Cundiboyacense in the center of Colombia. The Bogotá savanna has an extent of 4,251.6 square kilometres (1,641.6 sq mi) and an average altitude of 2,650 metres (8,690 ft). The savanna is situated in the Eastern Ranges of the Colombian Andes.

The Bogotá savanna is crossed from northeast to southwest by the 375 kilometres (233 mi) long Bogotá River, which at the southwestern edge of the plateau forms the Tequendama Falls (Salto del Tequendama). Other rivers, such as the Subachoque, Bojacá, Fucha, Soacha and Tunjuelo Rivers, tributaries of the Bogotá River, form smaller valleys with very fertile soils dedicated to agriculture and cattle-breeding.

Before the Spanish conquest of the Bogotá savanna, the area was inhabited by the indigenous Muisca, who formed a loose confederation of various caciques, named the Muisca Confederation. The Bogotá savanna, known as Muyquytá, was ruled by the zipa. The people specialised in agriculture, the mining of emeralds, trade and especially the extraction of rock salt from rocks in Zipaquirá, Nemocón, Tausa and other areas on the Bogotá savanna. The salt extraction, a task exclusively of the Muisca women, gave the Muisca the name "The Salt People".

In April 1536, a group of around 800 conquistadors left the relative safety of the Caribbean coastal city of Santa Marta to start a strenuous expedition up the Magdalena River, the main fluvial artery of Colombia. Word got around among the Spanish colonisers that deep in the unknown Andes, a rich area with an advanced civilisation must exist. These tales bore the -not so much- legend of El Dorado; the city or man of gold. The Muisca, skilled goldworkers, held a ritual in Lake Guatavita where the new zipa would cover himself in gold dust and jump from a raft into the cold waters of the 3,000 metres (9,800 ft) high lake to the northeast of the Bogotá savanna.

After a journey of almost a year, where the Spanish lost over 80% of their soldiers, the conquistadors following the Suárez River, reached the Bogotá savanna in March 1537. The zipa who ruled the Bogotá savanna at the arrival of the Spanish was Tisquesusa. The Muisca posed little resistance to the Spanish strangers and Tisquesusa was defeated in April 1537 in Funza, in the centre of the savanna. He fled towards the western hills and died of his wounds in Facatativá, on the southwestern edge of the Bogotá savanna. The Spanish conquistador Gonzalo Jiménez de Quesada established the New Kingdom of Granada with capital Santa Fe de Bogotá on August 6, 1538. This started a process of colonisation, evangelisation and submittance of the Muisca to the new rule. Between 65 and 80% of the indigenous people perished due to European diseases as smallpox and typhus. The Spanish introduced new crops, replacing many of the New World crops that the Muisca cultivated.

Over the course of the 16th to early 20th century, the Bogotá savanna was sparsely populated and industrialised. The rise in population during the twentieth century and the expansion of agriculture and urbanisation reduced the biodiversity and natural habitat of the Bogotá savanna severely. Today, the Metropolitan Area of Bogotá on the Bogotá savanna hosts more than ten million people. Bogotá is the biggest city worldwide at altitudes above 2,500 metres (8,200 ft). The many rivers on the savanna are highly contaminated and efforts to solve the environmental problems are conducted in the 21st century.
