Knowledge is fundamental to improving the competitiveness, responsiveness and levels of innovation that we see in industries. This research project aimed to determine how information and knowledge about water management and water use efficiency is being used and managed in irrigated cotton and grains and the key factors influencing decision making. To do this, 90 interviews of growers of cotton and grains, consultants, extension workers, government researcher officers, and irrigation equipment suppliers were conducted and a stakeholder workshop held to integrate and progress the findings.
