abstract = "The Chilean arid, semi-arid and sub-humid zone presents serious
problems associated with desertification processes. The region is
characterized by a precipitation concentrated in a few months,
with long dry periods during the year, and a high climatic
variability, associated mainly to the {"}El Niņo, Southern
Oscillation{"} phenomenon 3 . Due to this variability, there are
very dry and wet years, favoring the water erosion in the area. In
addition, the region has been historically over exploited by
different human activities, such as mining, agriculture and
livestock. In northern and central Chile, the climate may have
different roles in accelerating desertification. First by the
tendency to decreasing rainfall during the 20th century and in the
early 21st century, second by the increase in rainfall variability
and the intensity, increasing its erosive effect.. Besides this,
climate projections indicate a more aggressive climate in the
future, contributing to the soils and ecosystems degradation 6 .
The main objective of this work is to seek a better understanding
of the desertification processes associated with pasture in
different dry regions of Chile, and to investigate possible
changes in these mechanisms under future climate projections.",
