Abstract:
The municipality of Cajazeiras-PB, located in the western portion of the State of Paraiba -
Mesoregion of Sertao Paraibano - presents geoenvironmental characteristics
peculiar, due to the semi-arid climatic conditions in which this
subject. The pluviometric indices present averages of 800 mm / annual
distributed irregularly in time and space, high temperatures during
the year and the negative water balance promoted the formation of little soils
deep sea and installation of a low density vegetation - Caatinga, which
naturally it promotes the development of erosive processes. The pressure
demographics and the use of inappropriate cultivation and soil management techniques make
this environment is susceptible to triggering desertification processes.
In view of this, this work seeks in general to investigate the existence or not
of the desertification process in the municipality of Cajazeiras - PB in three spheres: the
natural or climatic, human or anthropogenic and anthropoclimatic. The methodology
applied research was conducted based on the methodology of Birkeland (1974), for the study
natural / climatic and the approach adopted by Dill (2007) to analyze
human / socioeconomic. The combination of these methodologies enabled the analysis
anthropoclimatic through a qualitative analysis based on the results of the
natural and anthropogenic dimensions. Furthermore, the results found showed a
environmental / natural balance of the study area and an index of degradation of
53.26%, thus not constituting a desertification in any of the three spheres. O
that there is in fact a degrading picture in growth that has not become
as a problem, it can definitely lead to the installation of desertification.
