Climate change, mitigation and adaptation: the case of the Murray–Darling Basin in Australia

For the more moderate climate changes projected for 2050, the complementarity
between adaptation and mitigation reflects more specific features of the
projections. In the ‘adaptation only’ simulation, the increased frequency of
drought reduces the set of adaptation options, and precludes most high-value
horticultural activities and opportunity cropping based on irrigation in Wet
states only. By contrast, in the simulations where both adaptation and
mitigation take place, reduced water availability in all states of nature leaves
open a wide range of adaptation opportunities.
