About

Jack Koci is an earth and environmental scientist with a particular interest in tropical catchment geomorphology and water quality. He has experience working across university, Government and industry and currently conducts research and teaching within the School of Earth and Environmental Science at James Cook Unviersity.

Jack's current research primarily focusses on improving understanding of the causes, processes, impacts and management of soil erosion in tropical landscapes. Jack also uses novel drone-based remote sensing techniques to map, monitor and model tropical landscapes.

Prior to joining James Cook University, Jack worked as a Research Fellow at the University of the Sunshine Coast. He has also worked with Seqwater and the Australian Centre for International Agricultural Research (ACIAR).

Current Funding

Current and recent Research Funding to JCU is shown by funding source and project.

Great Barrier Reef Foundation - Reef Trust Partnership

GBRF EOI Island Monitoring

Indicative Funding: $397,435 over 2 years (administered by Department of Environment and Science)
Summary: The more than 1000 islands and cays in the Great Barrier Reef (GBR) World Heritage Area (GBRMPA spatial data, 2019) support a diverse range of ecological, cultural and economic values. Many are threatened by climate change, but monitoring and management is difficult as many cays are remote and difficult to access. This project will develop and implement an efficient drone-based hierarchical monitoring protocol based on the recognition and use of `natural ground control points? that will enable more rapid and resource efficient capture of reef island status to inform management decisions.

Effectiveness of gully remediation in catchments draining to the Great Barrier Reef

Indicative Funding: $43,089 over 1 year
Summary: Gully erosion is a globally significant land degradation problem and major contributor to poor water quality in the Great Barrier Reef (GBR) World Heritage Area. Gully rehabilitation can stabilise erosion and reduce downstream sediment yields, but the globally observed responses to rehabilitation are variable. This project will evaluate sediment yield and vegetation responses to several gully rehabilitation measures implemented in the Burdekin River catchment. The project will provide valuable new knowledge and understanding of the effectiveness of gully rehabilitation in savannah rangeland landscapes tributary to the GBR, and elsewhere in the world.
Investigators: Jack Koci in collaboration with Rebecca Bartley and Scott Wilkinson (College of Science & Engineering and Commonwealth Scientific & Industrial Research Organisation)
