UTS: Food Security with Dana Cordell

The Australian food system is currently operating under a deficit model where environmental, public health, and economic costs are outpacing benefits. While agriculture is a pillar of the national economy and regional employment, it is facing acute pressures from climate change, geopolitical instability affecting supply chains, and rising food insecurity. A critical, yet often overlooked vulnerability is 'phosphorus security.' With Australia being the world's fifth-largest importer of phosphate—a finite resource controlled by only five countries—regional producers face significant risks from price spikes and supply disruptions, similar to those seen in the fossil fuel sector.

To safeguard the future of Australian agribusiness, a transformative shift toward a Circular Economy is required. This approach moves beyond simple waste management to a model of regeneration and resource recovery. Key opportunities include the development of renewable fertilizers derived from organic waste, manure, and wastewater, which can insulate farmers from global market volatility while improving soil health and water security. Furthermore, decarbonizing the sector is essential, as the food system contributes approximately 40% of Australia's greenhouse gas emissions.

Achieving Net Zero and ensuring long-term viability requires a 'stacked benefits' approach, where solutions address climate resilience, nutrient security, and public health simultaneously. For regional businesses, this transition involves moving from product-based models to service-based models (such as selling crop nutrition rather than just fertilizer volumes) and embracing cross-sector collaboration to prevent technology lock-ins. The transition demands not just technological readiness, but market and stakeholder readiness to overcome systemic regulatory and financial barriers.
