  • The Orinoquia and Amazonia in figures

Amazonia is a plain that borders with the Guaviare River in the north, and westwards it does not go beyond a level of 500 m on the eastern slope (Figure 8). With many streams and fast-flowing rivers, the Amazonia region covers more than 230 thousand squared kilometers, including around 40% of the national territory. This region—known as “the lung of the world” because of its abundant and dense tropical rain forest—contains 11 of the 56 protected areas in the country, and is host to 185 Indigenous reserves and 1,210.549 inhabitants.


The Colombian Orinoquia extends from the Meta department to the Orinoco River basin bordering with Venezuela.
The Orinoquia comprises 92 sub-basins (Correa, Ruiz et al. 2006) and has a uniform tropical climate all year round. The region hosts 156 types of ecosystem of which 92 correspond to natural ecosystems (Romero, Galindo et al. 2004). The 32 types of savannah are grouped in two categories: high plains, and flood plains.
