Harnessing technology to assist in environmental management

Environmental Informatics studies how information can be acquired, processed, modelled and communicated for environmental sciences and management. It is an important multidisciplinary research field covering several national research priorities, including frontier technologies, smart information use, protecting Australia from invasive diseases and pests, sustainable use of Australia’s biodiversity, responding to climate change and variability, and transforming existing industries.

KEY PROJECTS

Early detection of dangerous pests and plant diseases: Current detection and identification of plant diseases and pests mainly rely upon visual identification by human experts. It is labour intensive, highly dependent on the availability and experience of the diagnosticians, and lacking in quality assurance. This program will develop new sensing technologies and automatic biosecurity surveillance systems for early detection of plant diseases and pest incursions before they cause damage to the local industry and region.

Evaluating the environmental impacts of global climate change and industrial activities: This program analyses the changes of vegetation and soils and their relationship with the global climate change and industrial activities. These measurements facilitate anomalies detection, such as those caused by environmental changes, and track their progress through shifts on plant anatomy.

Machine vision for automated harvesting, grading and packing of crops: This program aims to develop image processing and machine vision techniques for the detection, recognition, and analysis of fruits and other crops in a greenhouse environment, in order to assist the development of automated harvesting systems.

Coastal environmental monitoring and management: This program aims to develop an effective and quantitative monitoring technique for Australia’s coastal area. This includes monitoring of shoreline changes and the spectral and spatial changes of seagrass distribution and quality. The monitoring results can be used for reliable assessment of environmental impacts, and assist with making remedial plan and preventative works.

Computer vision for environmental monitoring and surveillance: This program aims at developing novel computer vision and machine learning methods to identify moving objects and fusion of multi-modal image data.
