text: Australian rangelands cover approximately 75% of the nations land mass. Characteristically arid and semi arid the rangelands offer wide variations in climate, land and soil. The pastoral industry and particularly pastoral practices equate to 60% of rangeland usage. Subsequently, Australias 25.5 million beef cattle generate a gross average of $7.4 million per year. The Northern Rangelands are the centre for beef productivity in Australia, producing 70% of national beef in the year 2005 - 2006. The grazing of cattle is the primary use of Australias Northern Rangelands, and as such, it has enabled them to become a central organ for Australian agricultural enterprises. The production of beef in these rangelands draws upon a traditional low input-low output system of land management. Australias Northern rangelands have engaged in recent innovations to increase beef productivity whilst reducing greenhouse gas emissions. These strategies include; improving herd genetics, utilising feed bases, and promoting both feedlot finishing and property infrastructure. Species of cows such as the Red Angus, Tuli, Belmont Reds, Senapol and Brahman bulls are common species utilised in the Northern Rangeland industry for sustained productivity and carcass yields given Australia's arid and semi arid climate.
  NAPCO has adopted these strategies and complemented them by utilising solar energy systems, perennial pastures and minimum tillage to increase productivity and limit carbon emissions. Further, the company has significantly contributed to developing a genetic improvement program which has introduced a tropically adapted cattle breed which has improved fertility and growth. NAPCO's composite cattle breeds, the Alexandria and Kynuna composites, are suited to arid and semi arid climates which are the product of the environmental conditions in the northern rangelands.  The composite cattle proves to be more durable compared to the Shorthorn cow variations, due to their increased drought and disease resistance and heat tolerance. The composites are a more profitable long term species for NAPCO that has ensured beef productivity has been maintained whilst minimising environmental degradation.
