Currently biosecurity prediction is highly uncertain. Plant industries need more confidence in planning for biosecurity investments. The current system depends on expert opinion on a number of questions. While this may be the best available system to prioritise threats at present, it is well known that opinion is susceptible to bias and possibly misleading prioritisation.

Research outcomes:

Our research showed that multi-criteria decision analysis is an effective vehicle for the communication of results of economic analyses, technical scientific information and personal experiences to groups of decision-makers. These decision makers may be deciding on how much industry money to invest in species-specific research and development activities, government agencies forming part of the biosecurity continuum, industry and regional cooperative institutions, or local governments allocating money to pest and disease control activities. If supported by a transparent, interactive tool revealing group and individual preferences, experts capable of conveying their knowledge in a clear fashion and adequate technical information about pests, the technique we have developed is a highly effective decision-facilitation device.

In a trial setting it has been successfully used to prioritise a diverse list of pests and diseases affecting different industries. An interesting finding of our research is that introducing information about uncertainties in future pest impact scenarios does not necessarily have a significant impact on pest prioritisation. While the use of quantitative models to provide effective expert testimony on the market impacts of pests proved very successful, the relative uncertainty/quality of that information appeared to have little effect on decision-maker priorities. This being the case, there may be scope to further simplify the deliberative process to make group decision facilitation more rapid.

Research implications:

The range of possible impacts society may face in the future as a result of pest and disease incursions should be taken account of when planning risk mitigation activities. For instance, industry and government research and development programs targeted towards future threats should take into account forgone opportunities to invest in other activities that could potentially produce large benefits for the community. This is particularly true of invasive species that have both cultivated and wild native hosts since an outbreak can produce both market and non-market impacts. If only the market impacts are taken into account during industry and government strategic plans, there is a danger species with environmental and social impacts may be under-funded. The implications of this research project for all members of the biosecurity continuum are that practical tools have been developed to enable both market and non-market impacts of pests and diseases to be accounted for when planning for the future. To be most effective they require diverse groups coming together and talk about specific threats and a willingness to understand alternative points of view and joint approaches to risk mitigation and management.
