Development of a system dynamic model for the implementation of IWRM in South Africa
Expanded Title:BACKGROUND AND AIM This is the main report on a research project funded by the Water Research Commission over a period of 33 months. The project titled “Development of a System Dynamics Model for the Implementation of Integrated Water Resource Management (IWRM) in South Africa” consisted of two Phases namely, “Phase 1: Deriving Performance Indicators for IWRM on a Catchment Scale” (K5/1911/1) and “Phase 2: Pilot Implementation and Design of a Performance Management System (PMS)” (K5/1973/1). The vision behind the project was to provide a tool that could facilitate with the management of a catchment and the implementation of IWRM. The concept of Integrated Water Resource Management (IWRM) emerged in the 1980s due to increasing pressure on limited water resources from various users, the recognition of ecosystem requirements, pollution and the possible decline in water availability due to climate change. The implementation of IWRM has however been difficult and has had varying degrees of success. In South Africa, the Department of Water Affairs (DWA) is currently responsible for water resource management at a national level. The National Water Act (Act 36 of 1998) requires that Catchment Management Agencies (CMAs) be established for all Water Management Areas (WMAs) in South Africa. Each CMA will manage the water resources within its WMA at a regional level thus decentralising the responsibility and authority from DWA. This progressive devolution of responsibility and authority to the CMAs is a vital component of IWRM in South Africa While the National Water Act is clear on the need for IWRM, its practical implementation has always posed many challenges, mainly as a result of the inherent complexity of water resource systems and the large variety of aspects to consider. In an attempt to bridge this gap, the aim of the study was to develop a support tool, in the form of a Performance Management System (PMS), which could be used by institutions like CMAs .
