Regenerative agriculture is being used by a small number of innovative farmers in Australia and elsewhere, using a range of holistic methods that work with the land and climate, such as short duration time of controlled grazing with long rest periods for the paddock and higher proportions of aboveground biomass, to improve soil health and farm profitability. This paper uses a delta life cycle assessment, focusing only on the differences between regenerative and conventional production systems to assess the potential impact of regenerative agriculture on a full range of midpoint impact categories and end‐point areas of protection for an extensive sheep system in Australia. We assess the potential improvement to the water, carbon, and biodiversity footprints of sheep production, and find that regenerative agriculture has the potential to improve environmental performance compared with current industrial agricultural practices. In particular, there seems to be considerable potential to offset a significant proportion of the on‐farm climate change impacts through a combination of biosequestration in soils and aboveground biomass and using harvested biomass to offset fossil fuel use. The assessment highlights the need for additional data to confirm the findings and the potential contribution that regenerative agriculture can make to sustainability of ruminant livestock production.

绵羊饲养系统中再生农业的三角洲生命周期评估

澳大利亚和其他地方的少数创新型农民正在使用再生农业，它采用了一系列与土地和气候有关的整体方法，例如控制放牧的持续时间短，围场休息时间长，以及高比例的放牧。地上生物量，以改善土壤健康状况和农场盈利能力。本文使用三角洲生命周期评估，仅着眼于再生生产系统与常规生产系统之间的差异，以评估再生农业对澳大利亚广泛的绵羊系统的所有中点影响类别和保护终点的潜在影响。我们评估了绵羊生产中水，碳和生物多样性足迹的潜在改善，并发现与目前的工业化农业实践相比，再生农业具有改善环境绩效的潜力。尤其是，似乎有相当大的潜力可以通过结合土壤中的生物固存和地上生物量以及利用收获的生物量来抵消化石燃料的使用来抵消很大一部分农场对气候变化的影响。评估强调需要更多的数据来确认调查结果以及再生农业对反刍动物牲畜生产可持续性的潜在贡献。通过结合土壤中的固存和地上生物量，并利用收获的生物量来抵消化石燃料的使用，似乎有相当大的潜力来抵消大部分农田气候变化影响。评估强调需要更多的数据来确认调查结果以及再生农业对反刍动物牲畜生产可持续性的潜在贡献。通过结合土壤中的固存和地上生物量，并利用收获的生物量来抵消化石燃料的使用，似乎有相当大的潜力来抵消很大一部分农场对气候变化的影响。评估强调需要更多的数据来确认调查结果以及再生农业对反刍动物牲畜生产可持续性的潜在贡献。Integr环境评估管理2020； 16：282–290。©2019 SETAC
