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?

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.
