This document discusses engagement with horticultural growers in the Virginia and Northern Adelaide Plains region of Australia about facilitating climate change adaptation. It describes reviewing existing information on communication, vulnerability, practices and impacts. A vulnerability assessment was conducted to identify the most vulnerable areas to engage growers about. The best engagement tools and understanding grower knowledge, networks and champions is important. Scientific information needs to be translated into contextual, accurate and easy to understand terms for growers regarding potential impacts over short, medium and long time frames to help with decision making under uncertainty.
