Our Conference

Australian agriculture today is largely unsustainable. Soils are degrading and are in need of regeneration and broad acre farming is delivering food in quantity but not always in quality. An exceptional group of speakers address the question: Can we feed ourselves and not destroy the Earth?

Her current research and development interests include national and international sustainable food and nutrition security/systems, One/Planetary Health, gender equity and Science Communication.

Justin Borevitz grew up on an experimental farm in California. He his undergrad at UC and Wollongong and PhD / postdoc at UC San Diego/Salk. He was AProf at Univesity of Chicago. He has been at t he ANU since 2012 where he is researching landscape regeneration technologies for Food Ecosystem and Climate Security.


Admiral Chris Barrie commanded the Australian Defence Force (1998-2002). He is the Chair of PTSD-Australia New Zealand, whose subsidiary “FearLess Outreach” is able to assist about 6 million people in Australia and New Zealand who live with PTSD. At the Australian National University, Chris is an Honorary Professor. He has worked in the Tuckwell Foundation, and is Patron of the Australian Crisis Simulation Summit, a student led national one-week event for aspiring national security policy makers.He is an outspoken commentator on Climate Change and Security to raise awareness of the potential costs of inaction. He is an executive member of the Australian Security Leaders Climate Group and represents Australia on the Global Military Advisory Council on Climate Change.

Wolfram Buss is a researcher at the Australian National University working on land-based carbon sequestration techniques and how to maximise their potential in agricultural systems. He obtained his PhD from the UK Biochar Research Centre at the University of Edinburgh in 2016. His research combines biology, soil science and agriculture with environmental sciences, environmental chemistry, and engineering. Since finishing his PhD, he has worked as a post-doc at the University of Edinburgh, CSIRO and ANU.

Adam Caroll completed his PhD in Plant Biochemistry at the University of Western Australia in 2008 developing mass-spectrometry-based proteomics and metabolomics technologies and software and applying them to understand plant responses to abiotic stress and the biochemical functions of plant genes in these responses. From 2009-2017, he continued this line of research at the Australian National University as a postdoctoral researcher and expanding into the development of robotic automation for high-throughput biochemical analysis.
Since 2017, Dr Carroll has been managing the RSB/RSC Joint Mass Spectrometry Facility (JMSF) at the ANU where he and his team help researchers from inside and outside the ANU to use mass spectrometry to tackle an ever-growing array of exciting and important research problems across many fields of research. After-hours, Dr Carroll works as a volunteer with the Southern ACT Catchment Group to do bushland restoration work and develop a new volunteer-driven citizen science platform using a professional-grade mapping drone to map and monitor bushland ecosystem health and the ecological restoration of degraded former farmlands in the ACT by ParkCare volunteers.

Dr Nicole Chalmer gained a Bachelor of Science and Graduate Diploma in Agribusiness before going farming for 30 years. With her family she helped regenerate a badly degraded property Coronet Hill at Esperance, using ecological principles that included perennial pastures for cattle production. Approximately 500ha (including a 100ha wetland/lake) of their 2400 ha farm has been fenced as native bush mosaics.Experiencing the acceleration of ongoing market fluctuations, incorrect media perceptions of cattle production and Government interference became a concern. A deep discontent concerning the social-ecological sustainability of modern farming led to her completing an eco-environmental history PhD, analysing sustainability of food production systems, from the deep past, colonialism and present.

Gabrielle Chan is rural and regional editor of Guardian Australia. She has worked as a
journalist for more than 30 years, predominantly covering politics for News Corp and Guardian Australia. She has essays in Fire, Flood, Plague (2020), Meanjin and Griffith Review.
Rusted Off: Why Country Australia is Fed Up (2018), was shortlisted for both the Prime Minister’s Literary Awards and the Walkley book prize.
Gabrielle’s latest book, Why You Should Give a F**k About Farming (2021), examines how farming sits at the intersection of the world’s existential threats including climate change,
geopolitical tensions, soil loss, water shortages and food security. It argues that every eater
has a stake in the future of farming.
Gabrielle lives on a sheep and wheat farm west of Canberra

Nicole Chirlian is a beef cattle farmer from “Tallawang” Willow Tree on the Liverpool Plains NSW, using regenerative agricultural strategies since 2001.
