Abstract
World dairy production is growing rapidly having increased by 339 million tons over the last twenty years. However, it remains unclear how anthropic activities in the milk sector can impact the Ecosystem Services (ES) supply to society. The aim of this study was to propose and determine the Net Environmental Performance (NEP) of different milk production systems. For this purpose, a case study on a confined compost barn farm, located in southeastern Brazil was selected as reference scenario and compared with three other systems. The mapping of ES benefits was carried out using the Common International Classification of Ecosystem Services, while environmental impacts were calculated using Life Cycle Assessment (LCA). The LCA results and ecosystem benefits were combined and converted into monetary units to calculate the NEP per 1 kg of milk. The results indicated that semi-confined systems had the worst environmental performance (90 % more impacts) compared to the compost barn milk system. On the other hand, confined systems generate few ES benefits, but their environmental impacts were lower for most LCA impact categories (up to 87 % minimized impacts) compared to semi-confined systems. Finally, we concluded the confined systems in SP and PR showed the best NEP (1.07 and 1.48) aiming for both environmental impacts and ES benefits to fit the win–win situation.
期刊介绍:
Ecosystem Services is an international, interdisciplinary journal that is associated with the Ecosystem Services Partnership (ESP). The journal is dedicated to exploring the science, policy, and practice related to ecosystem services, which are the various ways in which ecosystems contribute to human well-being, both directly and indirectly.
Ecosystem Services contributes to the broader goal of ensuring that the benefits of ecosystems are recognized, valued, and sustainably managed for the well-being of current and future generations. The journal serves as a platform for scholars, practitioners, policymakers, and other stakeholders to share their findings and insights, fostering collaboration and innovation in the field of ecosystem services.
