Deux articles par l’équipe Urban Metabolism lab viennent de paraître dans les revues scientifiques à comité de lecture Ecological Indicators et Landscape and Urban Planning (top quartile « Q1 » Scopus). Le premier fait état des premiers résultats de la recherche doctorale « Urban Metabolism and Nature Based solutions » (FRS-FNRS Aspirant) menée par Úrsula Cárdenas-Mamani sous la direction de la prof. Daniela Perrotti. Le deuxième présente la première étude bibliographique sur l’utilisation de la notion d’espace et la compréhension des dimensions spatiales dans les recherches scientifiques sur le métabolisme urbain. L’étude est issue d’une collaboration interdisciplinaire et internationale de l’Urban Metabolism lab avec l’UMR ESO/CNRS, Université de Nantes, le Laboratory for Human-Environment Relations in Urban Systems, École Polytechnique Fédérale de Lausanne, et la Chair for Circular Economy and Urban Metabolism, Université Libre de Bruxelles.

Abstract
The growing evidence-base demonstrating that cities are responsible for accelerated natural-resource erosion and the exacerbated impacts of atmospheric emissions on climate change suggest the need for more systemic resource-use mitigation strategies at the urban scale. Nowadays, ecosystem service analysis provides an extensive reservoir of techniques and strategies to optimize the metabolism of cities through enhanced resource cycling and emission abatement. However, this reservoir is largely untapped in urban metabolism research despite substantial progress in ecosystem service knowledge and classification. In response to this knowledge gap, in this article we propose an integrated urban metabolism and ecosystem service framework to extend Economy-Wide Material Flow Analysis (EW-MFA). The framework utilizes “Pressures”, “Drivers” and “State” indicators to describe the relationships between anthropogenic and natural systems. A set of indicators was compiled from previous urban metabolism and ecosystem service studies to provide a shared and adaptable set of assessment categories across the two areas to jointly measure ecosystem services and resource flows. Through the proposed framework, interdependencies and causal relationships between ecosystem service assessment and EW-MFA flow categories can be identified. The focus of the paper is on elaborating the conceptual foundations of the framework and its analytical characteristics.

Abstract
The concept of urban metabolism has been profusely used by various disciplines over the last and current century to describe different urban phenomena. One theme that appears to gain importance in the interdisciplinary field of urban metabolism is the spatial dimension. In this article, we have carried out a bibliometric and qualitative analysis of the use of this multi-faceted notion in order to understand the place of space in urban metabolism research. Our results show that several communities within the urban metabolism field use and manipulate space for their research according to different approaches (territorial economic, socio-political, socio-ecological, governance and urban planning, and modeling). We discuss recent contributions of these communities and their approaches, their limitations, and a future agenda that might cross-fertilize them in order to embed space more consistently in urban metabolism research.
