Namibia's aridity is forcing its decision-makers to resort to new water resource Management approaches, including Water Demand Management (WDM). Such a change in Management approach is facilitated through the country's opportunity at Independence to rewrite and adapt ist old policies, including those for Water and Tourism. Old water-related policies in Namibia and South Africa have created a perception among the public that it is government's responsibility to provide water cheaply and in unrestricted quantities. The biggest challenge within WDM is to change the perceptions of society about the value of water and to instil a feeling of responsibility towards the resource as a whole. Legal support for WDM in form of the new Water Act is a crucial platform from which to plan the practical implementation of WDM throughout Namibia. In order to be able to put the policy into practice, it is imperative to understand which driving forces motivate people to adopt WDM initiatives. Within the Namibian tourism industry three main driving Forces have been identified which motivate managers of tourist facilities to implement WDM. This paper discusses how decision-makers can build on these driving forces in order to achieve increased water use efficiency in the tourism sector. Furthermore, how the relevant policies, the Water and Tourism Policies, can complement each other in order to achieve mutual goals, such as sustainable use of scarce natural resources.
