To mitigate the impact of soil losses due to water erosion and contribute to SOC sequestration and mitigation of GHG’s emission, Brazil has adopted public policies and national and regional plans to achieve high productivity and the intensification of agricultural activity, with a significative improvement of environmental quality. The main policies and plans with the projections of results are summarized below:
The effect of the plans and policies above in terms of potential of annual SOC sequestration in lands with different use and coverage was calculated using the parameters suggested by Lal et al. (2018) in a perspective of 50 years (Table 3). BMPs with ZT/CA and iCLF-CA involve integrating all the individual agricultural practices and technologies available to guarantee erosion control and to produce annual biomass in a sustainable and competitive manner (Freitas et al., 2000). The estimates point for a total value of annual soil C sequestration varying from 44.63 to 145.95 million tons (Table 4), where the maximum values are in the degraded pastures followed by lands for settlements and annual crops.
