ABSTRACT

Alternative food systems and networks, which have emerged around the world, are often fragmentary, reduced in size and frequently unfold in parallel, hardly linked to each other. Agroecology faces the challenge of scaling up these initiatives to gain size and a significant impact on food production and consumption. Within the agroecological movement, however, diverse conceptions exist of what a sustainable food system should be. It is thus necessary to reach an extensive consensus, from the perspective of agroecology, on the principles guiding the construction of such a system. This paper discusses the principles that would best steer the building of Agroecology-based Local Agri-food Systems (ALAS). To this end, a critical review of the scientific literature on alternative food networks and systems was performed. In so doing, we highlighted the aspects that one could consider as purely agroecological in nature and sought to bring them together to form a coherent proposal. Consequently, the present paper systematizes the main contributions of literature on alternative food networks and systems, taking into account the characteristics of sustainability from an agroecology viewpoint, and identifies the issues requiring further development. Several principles are proposed to define local food systems, based on the four dimensions of sustainability: environmental health, economic viability, social equity and the right to decide what, how and for whom food is produced.

摘要

世界各地出现的替代粮食系统和网络往往是零散的、规模缩小的，而且经常并行展开，彼此之间几乎没有联系。生态农业面临着扩大这些举措以扩大规模并对粮食生产和消费产生重大影响的挑战。然而，在生态农业运动中，关于可持续粮食系统应该是什么，存在着不同的概念。因此，有必要从农业生态学的角度，就指导这一体系建设的原则达成广泛共识。本文讨论了最能指导基于农业生态学的地方农业食品系统(ALAS)建设的原则。为此，批判性审查对替代食物网络和系统的科学文献进行了研究。在这样做的过程中，我们强调了人们可以认为是纯粹的农业生态性质的方面，并试图将它们结合在一起形成一个连贯的提案。因此，本文将替代食物网络和系统文献的主要贡献系统化，从农业生态学的角度考虑可持续性的特征，并确定需要进一步发展的问题。根据可持续性的四个维度，提出了几项原则来定义地方粮食系统：环境健康、经济可行性、社会公平以及决定粮食生产的内容、方式和目的的权利。
