When analyzing the data for the year 2008, it is possible to verify a deep modification of the
local landscape, where the areas of occurrence of the levels serious and very serious of land
degradation increased around 43.17% and 17.51% , respectively. The level very serious of
land degradation was not identified between the years 1987 and 2003, however, in 2008, this
level appears and represents 17.51% of the municipality. Activities that contributed to land
degradation are related to the exploitation of material for construction, deforestation of
savannah, livestock, cassava monoculture, forest fires and the presence of pests such as
termites and ants. Given the diversity of use and occupation of land, part of the municipality
is moving to the moderate to severe level, whose indicator is related to removal of material
building construction, and natural vegetation has suffered environmental impacts in relation
to the difficulty of regeneration, and in many places, due to impacts from activities of
livestock, the land are like abandoned areas (Fig. 8. A and B).
FIGURE 8: A – Areas of pasture in the lower part of the municipality - level moderate of land
degradation, with characteristics of abandoned lands. B – Area of level moderate to serious
of land degradation. Exploitation of the soil for civil construction.
4. CONCLUSIONS
The results indicated a strong tendency that natural resources in the municipalities
studied, over time have suffered environmental imbalance, with areas at risk of
desertification and with a strong impact in terms of land degradation on the one hand, and
secondly the results point to the inefficiency of the government to create public policies to
combat desertification and mitigating the effects of drought, which would allow the socially
and environmentally sustainable development, with risk reduction.
