Nr management in current Brazilian policies

• Nitrogen input from human activities escalated significantly in Brazil from 1970 to 2015: emissions of nitrous oxide (N2O), ammonia (NH3), and
  nitrogen oxides (NOx) together have increased about 350% in the period.

• Nr emissions are mainly related to agricultural practices and use of fertilizers, unmanaged animal
  waste, land-use change associated with biomass burning, increasing fossil fuels use, and lack of basic infrastructure for sewage treatment.
