Modelling & analytics
Transforming Australia’s biosecurity modelling capability
Biosecurity Commons will transform Australia’s biosecurity modelling capability by offering researchers and decision-makers a suite of standard tools and resources to produce consistent and transparent model outputs and analytics. These tools and resources include an intuitive point-and-click web interface, high-performance computing, repeatable scientific workflows, trusted datasets, a secure online workspace and cloud storage.
Five workflows will be available on the platform over the next two years (2021-2023). Each workflow will be peer-reviewed by a group of expert scientists and modellers from government, industry and research to ensure they represent the needs of the biosecurity community.
The platform will allow users to quickly and easily run workflows multiple times to investigate various scenarios using different datasets, methods and parameters. They can also be stored, shared and used to collaborate with other organisations or jurisdictions trying to solve similar biosecurity challenges.
Where might a pest or disease establish?
Understanding where an invasive species might establish is critical for biosecurity decision support, especially given the finite resources available for general surveillance. This workflow combines a series of datasets for abiotic suitability, biotic suitability and pest arrival pathways to estimate the likelihood of a pest establishing itself (“establishment likelihood”). The outputs of this workflow can be used as inputs to other workflows in the platform, such as Surveillance Design and Dispersal Modelling.
Where should we look for a pest or disease?
Preventing invasive species from arriving and establishing in Australia is one of the most cost-effective actions that can be taken to protect native species from invasive weeds, pests and diseases. The surveillance design workflow will offer a range of methods to explore different strategies for surveillance design, and will also include the option for users to generate species distribution models and risk maps that can be used as inputs for their analyses.
Where might a pest or disease spread to?
Dispersal models can be used to create visual outputs and analytics of the potential spread of invasive species, which can then be used in a framework for biosecurity surveillance, monitoring and management. The workflow will simulate the dispersal of invasive species across the environment using a variety of well-established scientific methods such as diffusion, gravity, and kernel models or a combination of these methods.
What impacts might a pest or disease cause?
Assessing the potential impact of an invasive species is an important step towards determining the appropriate biosecurity response. The impact analysis workflow measures the likely economic, environmental, and social impacts of an invasive species over time. This workflow will provide the capability to overlay land use, biodiversity and demographic datasets to identify the extent an area will be impacted by the incursion of an invasive species.
Resource allocation / time to eradication
How long will it take to eradicate?
Eliminating a pest or disease from an area may be required to minimise impacts to the environment, primary production or social amenities. The elimination of invasive species focuses on reducing their impacts as cost-effectively as possible. The resource allocation/time to eradication workflow will provide a range of methods to explore the eradication or control of a pest in a particular area, allowing users to explore different biosecurity management responses.
Proof of freedom
When is a region free of a pest or disease?
Proving the status of a pest or disease may be required for a number of circumstances, particularly relating to import and export markets. The Proof of Freedom model provides a high degree of confidence that an invasive species has been eradicated within a defined geographic area. This workflow will provide methods for sampling that is based on specifying a probability that the pest will be detected if it is present at a nominated prevalence.
Biosecurity Commons will connect users to a growing list of trusted datasets from large online repositories. What’s more, users will have access to relevant curated datasets, allowing them to save time sourcing, downloading and configuring data to meet their needs.
