Evaluating environmental, economic, and social aspects of an intensive pig production farm in the south of Brazil: a case study
Abstract Purpose The objective of this work was to quantify and understand the impacts of intensive pig production at family-farm level. A case study from the west of Santa Catarina State was used to identify adverse issues (hotspots) of pig production by integrating the assessment of the environmental, economic, and social aspects of the system. The quantitative and qualitative indicators calculated can guide and support the decision-making processes for a variety of stakeholders and actors. Methods The environmental performance of the pig production system was assessed from cradle-to-farm gate using environmental Life Cycle Assessment methodology set out in ISO 14040 (ISO 2006a). The functional unit (FU) was 1 kg of Liveweight (kg-LW). The structure of the Life Cycle Sustainability Assessment (LCSA) was based on Neugebauer et al. (J Clean Prod 102:165–176, 2015) and Chen and Holden (J Clean Prod 172:1169–1179, 2018), who proposed a tiered framework to evaluate the impacts on the environmental, social, and financial aspects of a product. The economic dimension or Life Cycle Cost (Hunkeler et al. in Environmental life cycle costing. Crc Press, London, 2008) focused on farm-level activities. The social impact was calculated based on the UNEP/SETAC (2009) guidelines. Results and discussion The environmental performance of the finishing pig production was slightly lower than reference value for climate impacts, acidification, and eutrophication. The economic impacts tended to be positive, reflecting the efforts of the farmer and employee to maintain high productivity and reduce the number of pig losses in comparison with the reference values. However, this effort did not result in greater profitability, causing low farm income. The impacts of low profitability were not transferred to the employee since the wage were above the reference value. There is a need for more education for small farmers, which is known to have a positive correlation with the adoption of new technologies, thus reducing adverse environmental and social impacts and increasing economic return. Conclusions The interaction of social and economic factors suggests it is unlikely that the farm can achieve better environmental performance. The limited economic return and low level of education have a negative impact on the farmer’s capacity to adopt new technologies to improve environmental outcomes. The use of LCSA, based on a consistent model across the three aspects of sustainability, made it possible to understand the interaction of these factors.
期刊介绍:
The International Journal of Life Cycle Assessment (Int J Life Cycle Assess) is the first journal devoted entirely to Life Cycle Assessment and closely related methods. LCA has become a recognized instrument to assess the ecological burdens and impacts throughout the consecutive and interlinked stages of a product system, from raw material acquisition or generation from natural resources, through production and use to final disposal. The Int J Life Cycle Assess is a forum for scientists developing LCA and LCM (Life Cycle Management); LCA and LCM practitioners; managers concerned with environmental aspects of products; governmental environmental agencies responsible for product quality; scientific and industrial societies involved in LCA development, and ecological institutions and bodies.
