Résumé
This report illustrates version 1 (V 1) of the multi-agent system (MAS) KatAWARE, which is being developed within the Water Research Commission (WRC) project "A Stakeholder driven process to develop a Catchment Management Plan for the Kat River Valley". KatAWARE is being developed through a participatory action research approach called Companion Modelling (ComMod) (Farolfi-Rowntree, 2005). According to this approach an iterative process of modeling and discussion take place between the research team and the local stakeholders. This process results in several versions of the model that should converge into a common and validated representation of the reality for local stakeholders participating in the co-construction of the model. A previous report (Farolfi-Bonté, 2005) provided a thorough description of the KatAWARE Prototype (from now on: KatA WARE P). Most of the changes introduced in KatAWARE V1 are the result of the discussions that took place during a workshop held with the Kat Water Users Association (WUA) in Fort Beaufort in June 2005 and dedicated to the presentation of KatAWARE P (Burt et al. 2005). The main changes with respect to KatAWARE P refer to the hydrologic component of the system, the new production functions that consider water shortage effects, the hierarchy in water provision for agents within a subcatchment, the introduction of regulatory framework (water licencing system), and minor adjustments in the financial, agronomic and socio-economic components of the model. New scenarios were also tested and some improvements in the interfaces were introduced. This report is organized in six chapters, all of them illustrating changes from KatAWARE P to KatAWARE V1 in a specific component of the model: the first chapter describes the changes in the model structure; chapter 2 depicts changes in the calibration of water supply, whilst chapter 3 refers to calibration of water demand. Chapter 4 is dedicated to the new framework of water licensing; Chapter 5 describes the new scenarios and finally chapter 6 illustrates the changes in output representations and model's interfaces.
