Item Open Access Modelling the potential impact of a water market in the Berg River Basin(University of the Free State, 2001-01) Louw, Daniël Barend; Van Schalkwyk, H. D.; Backeberg, G. R.English: An increasing number of economists believe that market mechanisms should be incorporated in water allocation policies. It is widely recognised that central planning as an economic system has been inefficient. In fact, it is impossible to plan efficiently from the centre, and the bigger and more open the economy is, the more impossible it becomes. The literature abounds with models for analysing alternative water allocation mechanisms. However, the positive mathematical programming (PMP) technique, which was introduced in this study, to calibrate the regional water market, is a relatively new approach. Modelling of water markets in South Africa has received very little interest in the past. This is probably because formal water markets were not permitted in the old Water Act (1956). The new National Water Act (1998) makes explicit provision for the transfer of water rights. However, the rules and procedures for introducing water markets have not been stipulated. To date no attempt has been made in South Africa to develop methodologies to simulate water markets. According to the new National Water Act one of the most important tasks of Catchment Management Agencies (CMA's) will be to design water allocation strategies for each of the major catchments in South Africa. This study contributes to enhance the capacity of water authorities to make economically sensible water allocation decisions. Without a market price, there is little or no incentive to use water efficiently. True pricing will lead to highest-value uses (e.g. drinking water and the production of high value products). Creating incentives for the most-valuable economic use of water will provide certainty; increase supply for more efficient uses, and create an even playing field for all water users including natural systems. There are legitimate concerns that the market mechanism per se will not guarantee equity. Government therefore has an important role to play in ensuring that the rules and procedures exist to deal with externalities. The secret is to achieve a balance that involves interfering in the market mechanism without jeopardising the proper functioning of water markets. The functional organisation for policy-making, water allocation, water management, and monitoring of users, plays an important role in the implementation of a sustainable water development system.
