THE STAGES OF THE DESERTIFICATION IN DIFFERENT TYPES OF SOIL IN THE SEMIARID PARAÍBA

Simone Mirtes Araújo Duarte

Abstract


The intersection of the outline information of the classes of soils and levels of degradation of land in SPRING V.4.2 allowed an assessment of conservation status of these, providing a first impression of what would probably be found in the field. The field work, and confirmed, helped in the interpretation and final conclusions on the levels of land desertification. The studies showed that the soils are quite eroded at different stages. Considering that the levels of degradation of land moderate, severe and very severe define the more advanced stages of desertification, showed that 82% of Cambisols, Luvisols of 85%, 78% of Neosols Regolithic and 89% of Neosols Litólicos are severely compromised the process of desertification. The commitment of Neosols Flúvicos is around 69%. This impairment is associated with the use of these soils in construction, in the manufacture of ceramics, but also by the launch of the presence of sewage and garbage and dead animals. These data, quite negative for the entire area of the city reflect the impacts caused by inadequate management of land, the pressure exerted by extensive livestock, which resulted and result in accelerated erosion processes, due to lack of technical assistance to farmers by the competent bodies to the adoption of practices related to soil conservation, and non-compliance with environmental legislation.
