Estudo de sistemas agrossilvipastoris sob a ótica da avaliação do ciclo de vida

Abstract

The ability to sustainably present food is one of the main concerns about stakeholder discussion forums worldwide. Among the questions about change, it advocates a warning framework for society of a possible food shortage. Brazil has a consolidated agricultural scenario and has favorable conditions for productive development that serve as sustainable premises. In particular, one of the main problems linked to production in relation to greenhouse gas emissions caused by this sector, which should contribute to the increase of the planet's temperature. One of the mandatory options for reducing and increasing carbon sequestration from agricultural activities is the removal of integrated systems such as Crop-Livestock-Forest Integration (ILPF). Thus, this study aimed to evaluate the feasibility of implementing the ILPF (agrosilvipastoral modality) system from the application of the Life Cycle Assessment Method (LCA). The results were related to the review with bibliometric methods using LCA in agrosilvipastoral systems and consequent results of CO2eq emissions (carbon dioxide equivalent) and carbon sequestration by systems in the Brazilian scenario. Brazil is one of the most public ILPF studies, mainly with agrosilvipastoral systems, but it is still in the question of LCA applications in forecasting. The results were related to the review with bibliometric methods using LCA in agrosilvipastoral systems and consequent results of CO2eq emissions (carbon dioxide equivalent) and carbon sequestration by systems in the Brazilian scenario. Brazil is one of the most public ILPF studies, mainly with agrosilvipastoral systems, but it is still in the question of LCA applications in forecasting. From the four phase simulations of ILPF with different combinations of soybean cultivation, grazing pasture provided by steers and eucalyptus forest, it was shown as variable from 17.66 to 17.92 Mg CO2eq / ha of ILPF in The productive arrangement and the drug balance were positive, presenting values from 26.82 to 29.07 Mg of CO2eq / ha in the 9 years period. From the results obtained it can be inferred that they are auxiliary in other LCA studies with specific production systems, contributing to the development of public policies and collaborating with scientific studies on soil quality without the agricultural sector sustainable development.
