Drivers Affecting the Adoption of Plant-Based Options to Manage Salinity
Current adoption of deep-rooted, perennial plants is currently too low to protect most parts of Western Australia from dryland salinisation. The adoption of these plants is substantially dependent on farmers voluntarily changing their farming practices away from a system based almost solely on annual plants. In order to understand the drivers of the adoption of salinity management practices, a mail survey was distributed to 940 landholders in the Wheatbelt and Great Southern regions. Of the 260 surveys returned, seventy percent of respondents considered salinity to be a current or potential problem on their property. Also, there is a general indication that landholders in both regions are aware of the plant-based options available to combat salinity. Classification tree analysis is employed to provide greater insight into the key drivers of the adoption of perennial plants. In accordance with adoption theory, initial analysis indicates that the profitability of perennials and the ease with which they fit into existing farming systems are key drivers of their popularity.
