Modelling the complex agri-food dynamics of France on the long duration (19th to 21st centuries)


A major current sustainability challenge is to achieve food supply security within the context of energy transition and climate change. Modern agriculture is massively dependent on non-renewable resources and energy. The objectives are to explore agri-food systems properties in space and time in search for possible structural invariants and to build a mathematical model able to reproduce dynamics and structures. Energy, land and nitrogen are included in the analysis as key resources including potential recycling options. A scientific challenge is to identify tipping points to system breakdowns and explore alternative sustainability paths. Data and methods: numerous archival and numerical data available in French statistics, reports as well as international trade datasets.
