Fig. 1. Selected interactions in the climate-electricity-water system. In this influence diagram the blocks of text represent system variables, and the arrows represent cause and effect links. The diagram presents a dynamic hypothesis concerning dominant feedback structures in the system. The variable ‘total demand for water’ refers to the aggregate water requirements of all sectors including the electricity supply sector. The variable ‘total demand for electricity’ refers to the aggregate electricity requirements of all sectors, including the water supply sector. The existence of multiple feedback loops raises the possibility that the system will respond in complex, nonlinear ways when perturbed by exogenous and endogenous forces.
