A review of the latest data from the Australian Bureau of Statistics identified the Australian horticulture industry to have the highest water efficiency of all agricultural industries returning $6,200 of value per megalitre used in Gross Value of Production (GVP) terms. Horticulture generated the highest GVP per hectare of production land used at $31,486, with the second-highest (viticulture) trailing at $7,720. Horticulture is now the second most valuable agricultural sector at $10.2 billion.
And the horticulture industry also has the lowest total greenhouse gas emissions and lowest greenhouse gas emissions per $ of GVP at 0.03 tonnes of CO2-e. Looking at the whole product lifecycle, horticulture can attribute low greenhouse gas emissions post-production to the high proportion of production located in peri-urban areas and surrounds. Hort Innovation Research and Development Lead Dr Anthony Kachenko said the changing climate, high energy costs and the emergence of water-related issues such as salinity, water contamination, reduced environmental flows and supply security has brought greater attention to the importance of on-farm efficiency.
With the increasing cost of agricultural inputs, such as water and energy, increasing the efficiency of these inputs remains an important issue for the industry. Dr Kachenko said horticulture had proved successful in its adoption of sustainable practices and moving forward, Hort Innovation would continue to support its industries to adopt greater sustainability approaches that avoid negatively impacting the environment. Initiatives which increase on-farm efficiency will be critical to ensuring the horticulture industry can not only become more productive and profitable but also improve environmental outcomes.
