The University of Southern Queensland (UniSQ) has been awarded $1.1 million in funding through the Australian Government’s Climate-Smart Agriculture Program, administered by the Cotton Research and Development Corporation (CRDC), to accelerate the commercialization of its innovative VARIwise precision irrigation system.
This cutting-edge technology, developed over a decade of research led by UniSQ’s Associate Professor Alison McCarthy, promises to revolutionize water management in agriculture by integrating artificial intelligence (AI), real-time data analytics, and adaptive control systems.
From Research to Reality: The Evolution of VARIwise
VARIwise emerged from a series of CRDC-backed national projects under the Australian Government’s Rural R&D for Profit program. Initially conceived to address the limitations of traditional irrigation methods—which rely on static soil moisture thresholds—the technology evolved through iterative on-farm trials and advanced modeling. Early prototypes focused on optimizing water use in cotton crops, but subsequent iterations expanded to incorporate dynamic, site-specific decision-making powered by machine learning algorithms.
The system synthesizes real-time data streams from soil moisture sensors, plant health monitors, weather forecasts, and satellite imagery to create hyper-localized irrigation prescriptions. Unlike conventional approaches, VARIwise’s AI-driven models adapt to shifting conditions, such as variable rainfall or heatwaves, ensuring water is applied only where and when needed. This capability marks a significant leap from manual or schedule-based irrigation, enabling farmers to respond proactively to both immediate weather events and long-term climate trends.
Proven Results and Industry Impact
Extensive on-farm trials across cotton and pasture systems have demonstrated VARIwise’s potential to reduce water use by 10% while boosting productivity by 5%. In one landmark study, cotton growers using the technology achieved higher yields with less water by aligning irrigation with crop stress thresholds and root zone dynamics. These outcomes underscore the system’s role in addressing stagnating water efficiency gains; since 2007, the cotton industry has seen annual improvements of just 0.3%, a rate insufficient to meet future climate challenges.
“VARIwise isn’t just incremental progress—it’s a paradigm shift,” said Associate Professor McCarthy, who leads the UniSQ Centre for Agricultural Engineering team. “By moving beyond soil-centric models to integrate plant physiology and predictive climate analytics, we’re empowering growers to make smarter, faster decisions. This isn’t just about saving water—it’s about future-proofing Australian agriculture.”
Commercialization and Next Steps
The new funding will support the translation of VARIwise from a research-focused tool into a user-friendly, commercial-ready platform compatible with existing irrigation infrastructure. Key steps include refining the interface for broad accessibility, enhancing scalability for diverse crops and regions, and establishing partnerships with irrigation manufacturers and agtech providers. The project also aims to embed training programs to accelerate adoption, ensuring farmers and agronomists can leverage the system’s full potential.
A Climate-Smart Future
As VARIwise moves toward commercialization, its development reflects a broader shift toward data-driven, climate-resilient agriculture. By transforming raw data into actionable insights, the system not only bolsters water efficiency but also strengthens the industry’s sustainability credentials—a key advantage in global markets increasingly focused on ethical production.
For Australian irrigators facing hotter, drier conditions, VARIwise offers a roadmap to thrive in an uncertain climate. As McCarthy concluded, “This is how we turn challenges into opportunities: by equipping our farmers with science that works as hard as they do.”
The Climate-Smart Agriculture Program’s Partnerships and Innovation Grant is part of the Australian Government’s $302 million commitment to advancing sustainable agricultural practices.
