In the case of corn, which had an increase in the
participation of the Center-West region and a reduc- tion in
the South and Southeast of the country, one of the possible
explanations is presented by Souza et al. (2018). According
to the authors, the shift over the last four decades of corn
production from the South to the North of the country,
especially to the Midwest, has been
brought about by the
increase in demand for the grain and
by the availability of
cheaper land. In addition, greater growth in terms of
production has been observed in the Midwest. However, the
South region stands out in terms of productivity.
analyze not only the effects of interdependence between
regions in the same culture, but also the processes of spatial
competition between different cultures.
The first group (cotton, rice, coffee, sugar cane,
orange and tobacco) has crops that tend to be concentra-
ted in
specific areas of the country and did not present
major
changes between 2008 and 2018. The second group
(beans,
corn and soybean) has the crops that increased
their area
between the two years, whereas the third group (banana and
tomato) contains those with smaller clusters
and with clusters
more spaced apart among themselves. In addition, the
cassava crop was not included in any of
the groups since it
has producers throughout the national territory and it presented
a reduction in high-high clusters
in the North and Northeast
regions and an increase in the South and Midwest of the
country.
The analysis of agricultural crops throughout the
national territory made it possible to understand certain
patterns of spatial association between different crop
profiles in the years under study. Thus, were identified those
regions that did not show major changes in the production
of their municipalities, and also those that were influenced
by, or influenced, their neighbors.
Finally, it should be noted that this paper is limi- ted
to the comparison of changes related to crops with greater
economic value. Future studies could focus on different
categories of cultures and analyze other mea-
ningful
variables, such as productivity, in order to enable
the analysis
of the sector’s peculiarities from different points of view.
The comparative analysis between different cul-
tures
allowed the identification of cultures with similar
characteristics, either by the concentration of munici-
palities in certain regions by the expansion of clusters
observed from 2008 to 2018 or even by the extent and
proximity between the clusters. Furthermore, the com-
parative analysis of different crops made it possible to
