Since the mid-1970s the south-west of Australia has displayed a warming and drying trend in its climate. Using parametric and non-parametric methods this paper provides a decadal assessment of the profitability, productivity and productivity components of over 250 farms in the region. The farm panel data are detailed descriptions of the physical and financial characteristics of each farm business from 2002/3 to 2011/12, a period of challenging weather-years. This study yields insights about farm characteristics and management strategies that have weakened or strengthened farm viability over the decade. In spite of the climate challenges experienced in the region during that decade, a majority of farm businesses improved their productivity and profitability.
