Pierre Mazzega is developing research on the modelling of environmental law, policy and governance as complex systems. He has various experiences, in different research contexts, on environmental modelling and on nonlinear data analysis and assimilation in models.

Engineer in geophysics (Strasbourg Univ.), doctor in earth observation from space, HDR (accreditation to supervise research - Toulouse Univ., France), he is senior scientist at the French National Centre for Scientific Research CNRS in the Geosciences Environment Toulouse research unit (GET UMR5563, France). He is affiliate researcher at the Strathclyde Centre for Environmental Law & Governance (SCELG), University of Strathclyde, Glasgow Scotland UK

With frequent travels between empirical observations and theory, he contributes to the establishment of dialogues and the construction of methodological bridges between often distant scientific cultures (eg approaches from the formal sciences and research questions built in the social sciences, and back) in order to address in a new way socio-environmental issues of the present, in diverse contexts.

Pierre is developing mainly research in interdisciplinary contexts. presently his activity focuses on:

  • Modelling of environmental law and policy systems
  • Modelling of environmental governance systems
  • Structured and non-structured data analysis


He has experience (/publications) in modelling, data analysis and nonlinear data assimilation / inversion in the following domains (interdisciplinary collaborations and field work):

  • Water resource management (France: water policy simulation platform policy; Southern India: groundwater and land uses)
  • Dynamics of vegetation in semi-arid environment (Sahel; Mali)
  • Dynamics of oceanic particle fluxes (Southern Indian Ocean)
  • Scales and patterns in population dynamics (theoretical ecology)
  • Oceanography from space (ocean tides, mean sea level)
  • Space geodesy (gravity field and geoid; Earth tides and tidal loadings)
  • 2017 - on: Board Member of the International Multidisciplinary Thematic Network "Biodiversity, Health and Societies in Southeast Asia, Thailand supported by CNRS, InEE (National Institute of Ecology and Environment).
  • 2016 - on: Foreign collaborator of the CNPq (Brazil) Research Group of Legal Studies "Natural Resources and Sustainable Development" (GERN / UnB), Faculty of Law and Institute of International Relations (IREL) - PI: Profa. Carina de Oliveira (FL/UnB), University of Brasília – Brazil.
  • 2011-2014: Director of the Franco-Brazilian international joint laboratory "Observatory of Environmental Changes", hosted at the University of Brasilia, Brazil (on secondment at the IRD)
  • 2011-2015: Member of the Steering Committee of the Multidisciplinary Regional Amazon Program (L. Emperaire IRD and A. Carneiro Filho SAE - Brazil)
  • 2008-2010: CNRS deputy director of the GET UMR5563 Toulouse.
  • 2008-2012: Member of the Scientific Council of the French Research Institute for Development (IRD, France)
  • 2002-2005: Member of the Scientific Council of the French National Spatial Remote Sensing Program (PNTS)
