Sheep production, profitability and greenhouse gas emission of mixed farming systems in Western Australia\u27s Wheatbelt

Abstract

The south-western agricultural area of Western Australia is a vital contributor to Australia\u27s agricultural output. It generates over $10 billion annually in agricultural production from 2017–18 to 2021–22 and more than$8 billion in export value over the same period. Mixed farming systems characterise the region, producing broadacre crops (primarily wheat, barley, and canola) and livestock. The region\u27s livestock industry is dominated by sheep production for meat and wool, and the state’s share of the national sheep flock in 2020–21 was at 18%. This report provides a comprehensive review and industry analysis of sheep production in WA, its economic significance, and associated greenhouse gas emissions. It examines the unique characteristics of WA\u27s mixed farming systems, their key economic and environmental drivers, and the innovative practices that underpin the sector\u27s productivity and profitability in a changing climat
