QAMECS : Qualité de l’Air dans la Métropole grenobloise – évaluation de l’Environnement, de la Santé et des coûts associés

  • Project funded by ADEME ( 2016-2019)
  • Coordinator: Rémy Slama (Inserm)
    [Emmanuel Prados (STEEP/INRIA) for INRIA partner]
  • Partners: INRIA (STEEP), Air Rhône-Alpes. CNRS, Sciences Po Grenoble, Inserm, IAB, Université Grenoble-Alpes
  • Abstract: Urban atmospheric pollution is one of the main threats to human health that can be to some extent controlled by public action. In Europe, many cities have implemented various types of low emission zones (LEZ, focused on traffic and heating emissions), France being a notable exception. Although fine particulate matter (PM2.5) is usually assessed through its mass concentration, other metrics, such as PM chemical speciation as well as the so far little considered oxidative potential (OP) of PM, are worth considering, both in terms of associations with human health and in the context of monitoring of the efficiency of LEZ.
    QAMECS covers all dimensions from atmospheric emissions, impact of meteorological conditions on air pollution human behaviours related to transportation, environmental levels, health, associated economic costs and societal awareness. The project relies on environmental measurements, modelling, repeated observational (representative) population studies, an existing mother-child cohort, a controlled human experiment, health impact and related economic assessment. It is conducted by a consortium of specialists of chemistry and physics of air pollution, economics, sociology, epidemiology, geography, in relation with local authorities. It will bring results important for urban planning, public health, and more fundamental research on the measurement of PM and assessment of their biological and health impact.

CITiES : Calibration and valIdation of Transport – land-usE modelS 

  • Project funded by the 2012 ANR program “Numerical Models”
  • Coordinator: Emmanuel Prados (STEEP/INRIA)
  • Partners: STEEP (INRIA), MOISE (INRIA), IRTES-SeT, LET, LVMT, IFSTTAR-DET, IDDRI, VINCI (Pirandello Ingenierie) and IAU-ÎdF.
  • Abstract: This proposal aims to foster the use of LUTI models for the design and evaluation of land use and transport policies by addressing these two impediments. This involves: (a) defining a calibration methodology and developing relevant and efficient algorithms to facilitate the parameter estimation of LUTI models; (b) defining a validation methodology, in both the historical and urban economics senses, and developing the related algorithms. In both cases, analyzing the uncertainty that may arise from either the data or the underlying equations, quantifying how these uncertainties propagate in the model, and performing sensitivity analysis to determine the relevance of the various data and model parameters are of major importance…

ESNET: Ecosystem services networks futures for the Grenoble region

  • Project funded by ONEMA via FRB (2013-2016)
  • Coordinator: Sandra Lavorel (LECA/CNRS)
  • Partners: LECA (CNRS), STEEP (INRIA), EDDEN (PACTE / CNRS), CEMAGREF (“Gestion des Territoires” dept.), Institut de Géographie Alpine (PACTE), ERIC (Université Lumière – Lyon 2).
  • Abstract:
    ESNET aims at assessing alternative futures of ecosystem services networks for the urban area of Grenoble, a city in the French Alps, under combined scenarios of urban development, climate change, and non urban land-uses. We hypothesize that ecosystem services are interconnected through their underlying ecological mechanisms and operate as networks from the local to the regional scales. These networks are underpinned by fundamental ecological processes as well as by human dynamics. ESNET will primarily address the ecological dynamics determining ecosystem services trade-offs and synergies, while incorporating human dynamics in terms of land-use futures and ecosystem services preferences by local stakeholders and policy makers.

TRACER: TRanus, Analyse de la calibration et des Erreurs, Retours sur Grenoble et Caracas

  • Project funded by Ecos-Nord
  • January 2012 – dec 2015
  • Coordinator: Laurence Tubiana (IDDRI), Tomàs de le Barra (Facultad de Arquitectura y Urbanismo, Venezuela)
  • Partners: IDDRI, STEEP, Facultad de Arquitectura y Urbanismo (Venezuela)
  • Abstract: Having quantified elements on urban dynamics is necessary if one wants to implement policies that are coherent with sustainable urban objectives. Land use and transport integrated (LUTI) models enable such a quantification. Their use has successfully increased in the framework of urban prospect where environmental issues are preponderant. A large dissemination of such tools in the local authority agencies is nowadays crucial to evaluate urban policies, yet limited by various difficulties, such as lack of robustness and calibration issues. The objective of this project is to bring answers to these limitations. We choose to focus on the Tranus model, one of the most used LUTI model. Our work will be organized in three research directions. First, we aim at analyzing how Tranus is used by local agencies. Then, a comparison between the Tranus implementation and use for the cities of Grenoble (France) and Caracas (Venezuela) is planned. And finally semi-automatic calibration tools will be developed, and an uncertainty and sensitivity analysis will be performed.

Le territorial analysé par son métabolisme 

  • Project funded by IXXI
  • 2013 – 2014
  • Coordinator: Serge Fenet (LIRIS)
  • Partners: STEEP, CERAG, LIRIS
  • Abstract:
    Dans le contexte des grands enjeux environnementaux et écologiques contemporains et futurs, les villes et territoires jouent un rôle qui va s’avérer de plus en plus incontournable. Concentrant un nombre sans cesse croissant d’habitants, consommant de grandes quantités de ressources, générant pollution et déchets et occupant de plus en plus de terres arables, les grands centres d’activités urbains impactent en effet toutes les échelles et contribuent à des transformations profondes de la biosphère. L’objectif de ce projet est de décrire et d’analyser le fonctionnement de ces territoires urbains (au sens large). Il s’agira tout d’abord de quantifier les flux de matières fabriquées, stockées, importées et exportées, puis de comprendre et d’analyser ces circulations énergétiques et matérielles au sein des territoires, mais aussi entre territoires. Pour ce faire, nous prendrons en compte à la fois les dimensions spatiales (portée des flux, effets à distance, impacts multi-échelles) et temporelles (effets différés, dynamiques non linéaires, effets de seuil, hystérésis) pour bâtir un modèle du métabolisme urbain, et nous nous baserons sur les connaissances extraites par un processus de fouille et d’apprentissage automatique sur les données liées aux agglomérations Lyonnaise et Grenobloise. Nous nous intéresserons ensuite à la caractérisation de la résilience de ce modèle par rapport à des perturbations réalistes, et chercherons à calculer et à tester des stratégies de gestion urbaine permettant de maximiser cette résilience dans le contexte de plusieurs scénarios de durabilité.
