Why does Australia need to mitigate food loss and waste to ensure food security?

Food waste in Australia is causing a massive financial burden on the country, with an estimated annual cost of $36.6 billion. Several factors, such as food loss and waste (FLW), inflation, unemployment, and low income, concurrently contribute to Australia's food insecurity problem. This study mainly focuses on FLW, which plays a significant role in Australia's food insecurity. This study finds that despite taking numerous initiatives, including the National Food Waste Strategy 2017, National Food Waste Baseline 2021, Australian Food Pact, and Sector Action Plan, the FLW approximately 7.9 million tonnes of food is wasted every year in Australia. This study explores that in 2022, food insecurity severely affects 21% or 2.1 million households, and 94% of households are concerned about not having enough food in Australia. The author finds that the FLW contributes to producing 17.5 m tonnes of carbon dioxide (CO2), 2628.3 gigaliters of water use, and 25 m + hectares of agricultural land use by generating food production. Therefore, this study aims to critically evaluate the FLW scenario and management strategies of the Australian government in order to achieve the sustainable development goal‐12 (responsible consumption and production) and target 12.3 of reducing food waste by 50% by the year 2030.
