      abstract = {This paper presents the development of an integrated  hydroeconomic model for a large water system in which urban  and agricultural sectors are the dominant water users, and  climate change presents a major environmental challenge.  The purpose of this model is to analyze the potential  effects of different institutional scenarios and policy  interventions on the environment and the regional economy,  under varying water availability conditions. Our approach  involves replicating base water use and environmental flow  conditions in order to build the capacity to adapt to  future climate-related water stresses. The modelling  framework integrates hydrology, economics, climate stress,  infrastructure constraints and institutional water supply  decisions to address water stress variability. We analyze  the effects of two water allocation policies, namely, water  markets and proportional sharing. The results show the  enhancement of economic benefits that can be achieved when  high-valued water users are prioritized in the study area.  We find that irrigated regions growing large quantities of  higher valued crops such as fruit trees, maize and tobacco  bear a smaller percentage of shortages than those with  lower-valued crops as climate stress intensifies. This  study informs strategies for water resource management in  South Africa and many arid regions, given the imminent  climate change impacts on water availability in coming  decades.},
