实现粮食系统的可持续性是一个全球优先事项，但对于如何实现这一目标有不同的看法。大致上出现了三种观点，在此定义为：效率导向、需求限制和粮食系统转型。这反映了对什么是实际可实现的，什么是可取的，由不同的价值观和意识形态的作用技术，我们与自然的关系，从根本上说，什么是“美好生活”的支持不同的概念。本文描述了这些新兴的观点，并探讨了其潜在的价值;突出了LCA在塑造这些观点中的作用;并考虑了如何将LCA定位于澄清思维和推进政策相关知识。它认为，需要做更多的工作，以了解粮食可持续性问题的不同方法的价值观。这可以说明利益攸关方为什么不同意，哪里存在真正的误解，哪里可能有共同点，以及商定的前进方向。(C)2013爱思唯尔有限公司保留所有权利。
Achieving food system sustainability is a global priority but there are different views on how it might be achieved. Broadly three perspectives are emerging, defined here as: efficiency oriented, demand restraint and food system transformation. These reflect different conceptualisations on what is practically achievable, and what is desirable, underpinned by different values and ideologies about the role technology, our relationship with nature and fundamentally what is meant by a 'good life.' This paper describes these emerging perspectives and explores their underlying values; highlights LCA's role in shaping these perspectives; and considers how LCA could be oriented to clarify thinking and advance policy-relevant knowledge. It argues that more work is needed to understand the values underlying different approaches to the food sustainability problem. This can shed light on why stakeholders disagree, where there are genuine misunderstandings, and where common ground is possible and ways forward agreed. (C) 2013 Elsevier Ltd. All rights reserved.
