Résumé
Within the Water Research Commission (WRC) project: "A stakeholder driven process to develop a catchment management plan for the Kat River Valley", the Companion Modeling (ComMod) approach (Barreteau et al, 2003) was adopted to help the local Water Users Association (WUA) in the task of defining a Catchment Management Plan (CMP) for the Kat River Valley. Two platforms, a multi-agent model named KatAWARE (Farolfi and Bonté, 2005; 2006) and a Role-Playing Game (Farolfi, 2006), were constructed in conjunction with local stakeholders through the ComMod approach. This document reports on the use of the multi-agent model. The following chapters refer to the Kat River ComMod experience; nevertheless some lessons learned during the described case study could be generalized to other possible applications in South Africa or elsewhere. This report is organized as follows: Chapter one recaps quickly the main characteristics of the KatAWARE multi-agent model in its various versions; Chapter two illustrates the use of the tool during a participatory workshop with the WUA, whilst chapter three concludes and provides recommendations. In the appendix some technical information is provided, on how to install and operate KatAWARE. (Résumé d'auteur)
