Using in-depth interviews this research assessed weather and climate related risks and adaptation responses for irrigated industries in the SA Riverland. Growers were asked about the advantages and challenges of the region for irrigated horticulture; climate challenges and how they were adapting to them; and their expectations for the region. Growers identified the region’s advantages for irrigated production as long hours of sunlight and dry climate resulting in less pests and diseases. The region’s challenges included availability of a reliable water supply, continued social licence to operate, and growing competition for water. These are risks that have emerged over the last decade due in part to the millennium drought. Climate challenges were increased summer storms, lack of chilling hours, extreme and abnormal temperatures which damaged mature or developing fruit. Challenges included a warming climate which could be managed with extra water - making growers ongoing access to irrigation water a risk. Growers’ perceived their largest threat from climate change and variability as their ability to manage their adaptation to the effects. Their ability to purchase water at an economically viable price played a large a part in this. Adaptation planning was also made difficult by uncertainty regarding the profitability of production they were involved in. Adaptation by changing types of production was hampered by a complex mix of grower’s past decisions, existing investments, life stage, and expectations for their businesses, industries and region’s future.
