Large-scale pasture restoration may not be the best option to reduce greenhouse gas emissions in Brazil

摘要: Cattle ranching accounts for 44% of the greenhouse gas (GHG) emissions from land use sector in Brazil. In response, Brazil has proposed a massive pasture restoration program that aspires to make more competitive while at same time reducing associated GHG emissions. Pasture restoration, however, is only one several intensification options could be employed achieve these goals. Here we analyze potential production, economic return and an strategy based mainly on compare its productive, performances with focused supplemental feeding (grain-feed supplementation grazing animals animal finishing feedlots). To this end, developed multi-sectoral, deterministic simulation model system applied it Mato Grosso state, largest producer earliest adopter intensive production. account emissions, performed life cycle analysis complete beef production cycle. Our results show heavily does reduce but produces least favorable outcomes when compared range alternatives. view results, should seek diversified strategies cattle climate mitigation policy.
