The evolution of surfaces covered by pastures is
complementary to that of forests, as the phenomena of deforestation
and forestation were induced by an increase and decrease,
respectively, in grazing lands. Built-up areas are few (only 5.24% in
1912 and reaching 5.50% in 1980), yet an expansion of this land
cover type occurred between 1980 and 2009 (from 5.50% to 8.46%).
