Climate Change is a „wicked‟ challenge to regional communities • Regional communities must move to an „adaptation„ phase well before the full impact is known or knowable • Adaptation has to occur in an uncertain policy and well as biophysical environments – Water – CPRS – Climate change • Adaptation is intuitively a „bottom up‟ process but can only occur effectively in an information rich environment

Bottom up consultation an essential and ongoing part of project • Project Steering Committee- – Farms liaison committee – Rivers liaison committee – Community liaison committee • Experimental Farms phase – Dairy advisory group – Dryland/broadacre advisory group – Horticulture/Viticulture advisory group

A final word from Charles Darwin “It is not the strongest of the species that survives, nor the most intelligent that survives.” “It is the one that is the most adaptable to change.”
