3.2 Innovated CDA Methodology
In Marília, section III, using the Innovative CDA Methodology (Vischi
Filho et al. 2017 and 2018), 20 large agricultural properties and 32
small properties were inspected, in just nine months, with a total
surface of approximately 27.7 thousand hectares. From January to
November 2017, 27,775 ha or 3,086 ha were diagnosed and evaluated, per
month. This methodology allows a detailed evaluation of an area, which,
using the old methodology, would take 103 months to be carried out (8
years and 7 months), instead of the nine months in which the work was
actually developed, therefore
Erosions and other soil degradation processes are reported in Table 2.
These inspections, which were already carried out, have received the
conservation technical projects for the areas and these have been
implemented.
3.2.1 Vegetation Cover Indicators
The improvement in vegetation cover, resulting from the changes in the
soil and water conservation management practices, were confirmed by the
comparison of aerial images from before the work was carried out (2002)
and after the work was carried out –(2013, 2017, 2018 and 2019) (Figure
2), that is, after the conservationist projects have been implemented.
At this point, the areas were already recovered, the erosions were under
control, and the i conservationist practices that transform soil
management had started to be applied, in the direction of Conservation
Agriculture practices.
