Abstract Urban development and the sprawl of transport infrastructures have disregarded the crucial function of metropolitan landscape in provisioning human well-being and biodiversity. This research aims to contribute to the challenges of Planning for Sustainability by proposing a Socioecological Integrated Analysis (SIA) to support the Land Use Master Plan in the Barcelona Metropolitan Area, to conciliate urban development with the performance of surrounding open spaces. The paper evaluates four different land cover scenarios (current, trending, alternative and potential), and two kinds of agricultural management (conventional and a socioecological transition towards organic agriculture). The results suggest that although there are significant improvements on job provisioning and nutrient-cycling closures (circular economy), certified organic agriculture is not enough to overcome some trends of industrialized agrarian systems such as low energy efficiency or poor improvements in greenhouse gas emissions. The results also show a crossed effect between social metabolism and landscape ecology where changes in the management could affect the landscape functioning while changes in the land covers are particularly affecting the resource use. Then, deeper changes that consider together land use and metabolic flows are required to promote more sustainable agroecological transitions. The SIA model is an important conceptual and methodological step forward that facilitates the transition towards sustainable land use policies.

通过巴塞罗那都市绿色基础设施的社会生态综合分析 (SIA) 评估对比土地使用情景的可持续性

摘要 城市发展和交通基础设施的扩张忽视了大都市景观在提供人类福祉和生物多样性方面的关键作用。本研究旨在通过提出社会生态综合分析 (SIA) 来支持巴塞罗那大都市区的土地利用总体规划，以协调城市发展与周围开放空间的表现，从而应对可持续发展规划的挑战。本文评估了四种不同的土地覆盖情景（当前、趋势、替代和潜在）和两种农业管理（传统和向有机农业的社会生态转型）。结果表明，虽然在工作提供和营养循环关闭（循环经济）方面有显着改善，经过认证的有机农业不足以克服工业化农业系统的一些趋势，例如能源效率低或温室气体排放改善不佳。结果还显示了社会代谢和景观生态之间的交叉效应，其中管理的变化可能影响景观功能，而土地覆盖的变化尤其影响资源利用。然后，需要同时考虑土地利用和代谢流的更深层次的变化，以促进更可持续的农业生态转型。SIA 模型是一个重要的概念和方法论步骤，可促进向可持续土地利用政策的过渡。结果还显示了社会代谢和景观生态之间的交叉效应，其中管理的变化可能影响景观功能，而土地覆盖的变化尤其影响资源利用。然后，需要同时考虑土地利用和代谢流的更深层次的变化，以促进更可持续的农业生态转型。SIA 模型是一个重要的概念和方法论步骤，可促进向可持续土地利用政策的过渡。结果还显示了社会代谢和景观生态之间的交叉效应，其中管理的变化可能影响景观功能，而土地覆盖的变化尤其影响资源利用。然后，需要同时考虑土地利用和代谢流的更深层次的变化，以促进更可持续的农业生态转型。SIA 模型是一个重要的概念和方法论步骤，可促进向可持续土地利用政策的过渡。
