ABSTRACT

This article presents the results of an ongoing research project on production and allocation of the biomass of agricultural origin (BAO), a key resource in ecological and energy transitions. The production and allocation of BAO are changing under the current development of the bioeconomy, which is the narrative promoted for intensifying the use of BAO, that we question through the lens of the scientific paradigm of bioeconomics. We developed a metabolic approach to agriculture, that we applied to the case study of northern Aube (France), an area specialized in intensive crop farming, undergoing rapid development of agricultural biogas production. Our results indicate that the ongoing changes influence BAO production and allocation at several scales (farm, small collective of farms, value chain, territorial). Development of the bioeconomy strongly influences the socioeconomic metabolism of the territory’s agriculture. Diversion of BAO flows due to biogas production are increasing structural imbalances and have some negative impacts on flows and ecological or economic funds strategic for sustainability, agronomic and economic balances of agricultural activities at multiple scales and as a whole. The changes described are especially disruptive since they strengthen competition and have blocking effects for the existing and potential agricultural metabolism.

摘要

本文介绍了一个正在进行的关于农业生物质 (BAO) 的生产和分配的研究项目的结果，BAO 是生态和能源转型的关键资源。BAO的生产和分配在当前生物经济的发展下正在发生变化，这是我们通过生物经济学科学范式的角度提出的加强使用BAO的叙述。我们开发了一种农业代谢方法，并将其应用于奥布北部（法国）的案例研究，该地区专门从事集约化作物种植，农业沼气生产正在快速发展。我们的研究结果表明，持续的变化会影响 BAO 的生产和分配在多个规模（农场、小型农场集体、价值链、地域）。生物经济的发展强烈影响着该地区农业的社会经济新陈代谢。由于沼气生产而导致的 BAO 流量转移正在加剧结构失衡，并对流量和生态或经济资金产生一些负面影响，这些资金对可持续性、农业活动在多个尺度和整体上的农艺和经济平衡具有战略意义。所描述的变化尤其具有破坏性，因为它们加强了竞争并对现有和潜在的农业新陈代谢产生了阻碍作用。多尺度和整体农业活动的农艺和经济平衡。所描述的变化尤其具有破坏性，因为它们加强了竞争并对现有和潜在的农业新陈代谢产生了阻碍作用。多尺度和整体农业活动的农艺和经济平衡。所描述的变化尤其具有破坏性，因为它们加强了竞争并对现有和潜在的农业新陈代谢产生了阻碍作用。
