Temporary analysis of the covering in antropic savannas of Sucre, Colombia

Abstract

The present work determines by satellites images interpretation the behavior of the covering of the anthropic savannas of Sucre, Colombia, from 1985 at 2017 emphasizing in its current state. In accordance with their structure the secondary savannas assemble: semi anthropic savannas, anthropic savannas, artificial wooded savannas and artificial without trees savannas. The results show in accordance with the percentage changes in function of the evaluated periods that the artificial wooded or without trees savannas increased their areas, what would imply a slow sucesional and persistent degradation of the whole system. It points out that the biggest negative cause is generally represented by the intensive cattle grazing and the adaptation of pasture through the persistent and successive deforestation and burns. Conclude that the system of anthropic savannas presents a slow degradation and that a loss of original biotopes exists.
