Abstract
The aim of this study is to develop an integrated model that can simulate the impact of
climate change on farm structure and adaptation thereof. The future sustainability of
the agricultural sector relies on the type of adaptation strategy put in place for
farmers to cope with the projected impacts of climate change. The Ceres Dynamic
Integrated Model (CDIM) was developed to evaluate different adaptation strategies,
results show that it is unlikely that high water tariffs will reduce the level of water
used for production. Depending on the availability of funds to make farm dams
available for farmers, access to farm dam capacity and winter water allocations as
well as increasing water use efficiency are potential adaptation options for the
farmers. Improved water management practices that increase the productivity of
irrigation water use may provide a significant adaptation potential under future
climate.
