Supporting decision for environment-friendly practices in the agri-food sector
Résumé
High-level decision-making, such as policy making, needs to take into account the often-conflicting
interests of different stakeholders with the goal of finding solutions to provide trade-offs and build
consensus towards the adoption of so-called win-win solutions. In this article, the authors suggest
that using a modeling and simulation approach would greatly enrich the deliberation process. The
authors propose a systematic method to assess possible options, based on the complementarity
of argumentation modeling and system dynamics (SD) simulation, in conjunction with field
experimentation. As a practical application, the authors assess various options available to agri-food
chain stakeholders when considering the adoption of cereal-legume intercrops as an alternative to sole
crops. Taking advantage of the argument analysis, SD simulations are used to: 1) compare different
cultural strategies available to farmers in current operating, market and regulatory conditions; 2)
propose plausible what-if scenarios anticipating technological progress, and exploring the impact of
adopting potential incentives and dissuasive regulatory measures.
