abstract = "Deforestation rates have been rising in the Brazilian Amazon since
2013 and a long-term planning to reduce trends requires an
in-depth understanding of the major drivers of land use change in
the region, such as cattle ranching. However, there is a lack of
large-scale evidence about how the technological and socioeconomic
conditions in which cattle ranching is practiced influence on
deforestation. This study assessed the contribution of different
cattle ranching systems to deforestation in the Brazilian Legal
Amazon from 2017 to 2019, and compared their trends in land use
change and stocking rate across time intervals within the period
from 2000 to 2019. Farming statistics were collected at the
municipal level from Brazils agricultural census of 2017.
Municipalities with a predominance of cattle ranching farms were
divided into four farming system groups, according to pairwise
combinations of higher/lower than average levels of adoption of
management practices and capital investment among farms. The
highest deforestation rates were found for municipalities with a
lower adoption of both management practices and capital
investment. These municipalities also had a significantly lower
density of slaughterhouses, and presented greater trends in forest
loss since the 2008-2012 period compared to municipalities in the
two farming system groups with a higher adoption of management
practices. The proportion of municipalities with significant
increases in stocking rate without significant increases in
pasture area started to rise in all farming systems since the
2008-2012 period, but still accounted for only 21% of total
municipalities during the 2012-2019 period. Agrarian settlements
were the land tenure category with the highest likelihood for
deforestation in all farming systems. Policies aiming to prevent
deforestation could consider increasing the adoption of management
practices among ranchers as one of the major strategies. RESUMO:
As taxas de desmatamento t{\^e}m aumentado na Amaz{\^o}nia
brasileira desde 2013 e um planejamento de longo prazo para
reduzir esta tend{\^e}ncia requer um entendimento aprofundado dos
principais fatores associados ao problema, como a pecu{\'a}ria
bovina. Entretanto, h{\'a} ainda uma falta de evid{\^e}ncia em
larga escala sobre como as condi{\c{c}}{\~o}es tecnol{\'o}gicas
e socioecon{\^o}micas da pecu{\'a}ria bovina influenciam no
desmatamento. Este estudo avaliou a contribui{\c{c}}{\~a}o de
diferentes sistemas de pecu{\'a}ria bovina para o desmatamento na
Amaz{\^o}nia ocorrido entre 2017 e 2019, e comparou estes
sistemas pelas suas tend{\^e}ncias de mudan{\c{c}}a de uso do
solo e taxa de lota{\c{c}}{\~a}o em intervalos temporais durante
o per{\'{\i}}odo de 2000 a 2019. Estat{\'{\i}}sticas foram
coletadas a partir do censo agropecu{\'a}rio brasileiro de 2017
em base municipal. Os munic{\'{\i}}pios foram divididos em
quatro sistemas de pecu{\'a}ria bovina, de acordo com
combina{\c{c}}{\~o}es de n{\'{\i}}veis maiores/menores que o
n{\'{\i}}vel m{\'e}dio de ado{\c{c}}{\~a}o de pr{\'a}ticas
de manejo e investimento em capital entre as fazendas. As maiores
taxas de desmatamento foram observadas para os munic{\'{\i}}pios
que tinham tanto uma menor ado{\c{c}}{\~a}o de pr{\'a}ticas de
manejo quanto de investimentos em capital. Estes
munic{\'{\i}}pios tamb{\'e}m tinham uma densidade
significativamente menor de frigor{\'{\i}}ficos, e t{\^e}m
apresentado maiores tend{\^e}ncias de perda florestal desde o
per{\'{\i}}odo de 2005 a 2012 se comparados aos
munic{\'{\i}}pios dos dois sistemas de pecu{\'a}ria com maior
ado{\c{c}}{\~a}o de pr{\'a}ticas de manejo. A
propor{\c{c}}{\~a}o de munic{\'{\i}}pios com aumentos
significativos na taxa de lota{\c{c}}{\~a}o sem aumentos
significativos na {\'a}rea de pastagem come{\c{c}}ou a crescer
desde o per{\'{\i}}odo de 2008-2012, mas ainda representou
apenas 21% do total de munic{\'{\i}}pios durante o
per{\'{\i}}odo de 2012-2019. Os assentamentos rurais foram a
classe fundi{\'a}ria com a maior propens{\~a}o ao desmatamento
em todos os sistemas de pecu{\'a}ria bovina. Pol{\'{\i}}ticas
p{\'u}blicas voltadas para a preven{\c{c}}{\~a}o do
desmatamento poderiam considerar o aumento na ado{\c{c}}{\~a}o
de pr{\'a}ticas de manejo entre os pecuaristas como uma das
estrat{\'e}gias mais importantes.",
