| There is growing evidence that freshwater availability is declining, while competition among sectors for the withdrawal of this scarce resource is rapidly increasing,(Rosegrant et a, 2002). Therefore, the need to promote inter-sectoral water use efficiency from the demand-side management has necessitated a study to investigate the responsiveness of different productive sectors and sub-sectors to water prices. Extracting data from the GTAP and UNIDO databases and adopting the marginal productive approach by Wang and Lall (2002),and using the two-stage-least squares method, the translog production function is estimated, from which the output and price elasticities and the marginal value of water is computed for thirteen sectors. The results indicate that... |

| Most of the climate change models for South Africa predict a reduction in freshwater availability by 2050. Population growth is projected at 3% per annum, implying increased domestic water use. In addition to these factors, the concern for ecological sustainability and increased water pollution due to increased industrial, mining and agricultural activities, water availability for sectoral production activities is expected to decline. This decline has an impact on sectoral output, value added and households’ welfare. Using a computable general equilibrium approach, this study investigates the possible impact of global change on households’ welfare. The simulation results show that water scarcity due to global change can potentially lead to a general... |
