abstract = "In the Amazon rainforest, land use following deforestation is
diverse and dynamic. Mounting evidence indicates that the climatic
impacts of forest loss can also vary considerably, depending on
specific features of the affected areas. The size of the
deforested patches, for instance, was shown to modulate the
characteristics of local climatic impacts. Nonetheless, the
influence of different types of land use and management strategies
on the magnitude of local climatic changes remains uncertain.
Here, we evaluated the impacts of large-scale commodity farming
and rural settlements on surface temperature, rainfall patterns,
and energy fluxes. Our results reveal that changes in
landatmosphere coupling are induced not only by deforestation size
but also, by land use type and management patterns inside the
deforested areas. We provide evidence that, in comparison with
rural settlements, deforestation caused by large-scale commodity
agriculture is more likely to reduce convective rainfall and
increase land surface temperature. We demonstrate that these
differences are mainly caused by a more intensive management of
the land, resulting in significantly lower vegetation cover
throughout the year, which reduces latent heat flux. Our findings
indicate an urgent need for alternative agricultural practices, as
well as forest restoration, for maintaining ecosystem processes
and mitigating change in the local climates across the Amazon
basin.",
