Abastract： （1）Overview and background of NICTA projects （2）System engineering and Automation of farm irrigation Water resources management presents an important research topic, because our planet is facing a serious water crisis. About 70% of all fresh water usage goes towards agriculture. Moreover, low water application efficiency is well reported in the literature. Improving on-farm irrigation efficiency can make a substantial contribution to a more sustainable utilization of the world’s fresh water resources. It is argued that systems engineering principles can assist to realize the goal of improving water efficiency or produce quality in on-farm irrigation whilst maintaining productivity and quality of service. In approaching this resource management problem, wireless sensor network technologies and automation ideas are combined to improve economic productivity in agriculture industries in such a way as to support continued growth in these major food industries in the face of a competitive water market. This presentation discusses the initial modeling of the viticulture soil-water dynamics using system identification methods. Then results of applying smart automation to irrigate an apple orchard will be presented based on real-time feedback control which increased economic water use efficiency by 73% compared with manual irrigation. （3）Demonstration of FarmNet; a web based platform for water resources management FarmNet is a national platform for improving the interconnectivity between people, devices, data, and information, specifically in the agricultural sector. FarmNet shall specify a national standard for seamless interconnectivity between agricultural software applications, sensors, agricultural models, GIS data sources, actuators, real-time messaging services, agricultural information services, etc. FarmNet will introduce new elements in this system such as social networking tools. Part of this standardization process will be to develop, or adopt and enhance existing ontology for data interchange, establish security protocols as well as implementation recommendations. FarmNet will also provide a set of core services including service discovery, and registration or new services. Some examples of FarmNet features and functionality include: (i) Tools for water allocation and trading; (ii) Tools for cost benefit analyses for on-farm infrastructure upgrades and changes in farm and land management practices; (iii) Irrigation network design tools; (iv) Performance of water in soils tools; (v) Tools to interpret new remote sensing data; (vi) Long- and mid-term rainfall forecasting; (vii) Local micro-climate forecasting tools; and, (viii) Carbon accounting and management tools.
