AGRI 7001 Agricultural Biosecurity

Credit Points 10

Coordinator Jonathan Plett Opens in new window

Description Biosecurity is a set of measures to prevent, respond to and recover crops and livestock from pests and diseases that threaten the economy and environment. Comprehensive biosecurity systems help ensure food security and food safety, which is crucial for community health, competitiveness for agricultural export and conservation of natural environments. This unit studies the epidemiologic triangle consisting of the host, disease and the environment in which the disease develops, and the series of measures and practices to detect and prevent entry and spread of pests, diseases and weeds. The potential for future biosecurity mega shocks to the agricultural industry, preparedness for rapid emergency responses to an exotic incursion, and management of invasion of pests and diseases will be discussed.

Learning Outcomes

On successful completion of this subject, students should be able to:
  1. Critically appraise biosecurity systems as applied to global food security.
  2. Identify diseases, pests and weeds that are the target of surveillance.
  3. Monitor plants and animals for signs of disease and pest infestation.
  4. Devise a biosecurity plan that is tailored to the needs of a specific area.
  5. Create solutions to dynamic complex problems in biosecurity by synthesizing information from a range of relevant data sources.
  6. Justify inferences and solutions to biosecurity issues to a range of audiences.

Subject Content

1.How farms and farm products are affected by microbes (diazotrophs, mycorrhizae, viruses, bacteria, fungi and nematodes), pests and weeds
2.Key concepts of epidemiology; the study of the distribution (frequency, pattern) and determinants (causes, risk factors) of disease-related states and events
3.Methods for diagnosis such as quantitative PCR as well as different sequencing and sensor technologies
4.The symbiotic relationships of microorganisms and insects with plants and animals and their use in biocontrol
5.Methods of control (cultural, chemical, biological, and genetics to breed resistant varieties) and their relative advantages and disadvantages,
6.Data modelling and visualisation together with increased data availability for long-term decision making
7.The relevant legislation and authorities (Biosecurity Australia, AQIS, TGA etc.).
8.The strengths and weaknesses of current biosecurity systems
