reduces energy costs but also aligns with the growing focus on Environmental, Social, and Gov- ernance (ESG) criteria. Additionally, farmers are in- vesting in water harvesting and on-farm water storage. Tech- niques such as building dams, reservoirs, and water tanks to capture and store rainwater en- sure a more reliable water supply during dry periods. Water-har- vesting systems, such as bunds or swales, help direct and cap- ture runoff, further supporting irrigation efforts when rainfall is scarce.
portant. We need to develop op- tions like recycled wastewater and even desalinated water in regions where freshwater is lim- ited. These alternative sources help reduce the strain on trad- itional water supplies and pro- vide a more reliable solution during times of drought. Some farmers are joining the energy transition by integrat- ing renewable energy sources into their irrigation systems. Solar-powered irrigation is be- coming increasingly popular, providing an environmentally friendly and cost-effective way to power pumps. This not only
Satellite imagery is one ex- ample of a practical solution. It offers a broader view of crop health over large areas without requiring expensive sensors on the ground. By providing de- tailed irrigation recommenda- tions through easily accessible platforms like smartphones, this technology can benefit farms of all sizes, making it a more scal- able and affordable option. Adaptation strategies In addition to adopting new tech- nologies, Australian farmers are using a range of practical strat- egies to adapt to water scarcity. Soil health management is a key focus, with some growers using techniques like cover cropping, reduced tillage, and organic mat- ter to improve soil’s ability to re- tain moisture. Healthy soil holds more water and reduces the amount needed for irrigation, helping farmers make the most of their resources. Crop diversification is another strategy, with farmers shifting to more drought-tolerant crops or growing a wider variety of crops. This approach helps build resili- ence against climate change and weather unpredictability. By di- versifying their crops, farmers can reduce the risk of crop failure while maintaining productivity. Alternative water sources will also become increasingly im-
Dave Cameron is the CEO of Irrigation Australia. Irrigation Australia provides essential training and certification programs, helping irrigation professionals develop the skills needed to manage modern systems. Its workshops and accredited courses focus on improving water use efficiency and reducing en- vironmental impacts, fostering a skilled workforce that can tackle the sector’s most pressing challenges.
