Figure 12-5: Risk response
surface incorporating cumulative probability plots (in shaded box) for climate
change magnitudes as indicated on x- and y-axes. Indicated percentage probabilities
are probabilities of climate change in northern Victoria in 2070 lying within
each shaded area (thus, there is a 100% probability of climate within the shaded
square, and a 50% probability of climate within the innermost region). Probability
(in percent) of irrigation water demand exceeding farm supply cap in any one year,
for indicated climate change, is indicated by oblique lines. Critical threshold
(heavy line) is set at a 50% chance of exceeding the cap (Jones, 2000).
