Climate change and increasing seasonal variability are challenging the production efforts of growers in lower rainfall environments of the Western Australian grain belt. Significantly less rainfall than the long-term average has fallen across southwest Western Australia during the past 30 years.
Seasonal rainfall has also become more variable with later starts to the growing season and a general shift to more summer and less winter rainfall. Day and night-time temperatures, particularly in winter and autumn, have gradually increased, while in some areas, the risk of frost in spring has increased.

As dairy farmers have strived to maintain profitability, many have farmed more intensively. More cows are milked and increasing inputs of fertiliser and purchased feed are used per hectare. However, these increased nutrient inputs have far exceeded the increase in nutrient output in milk production. The increasing nutrient surplus (inputs minus outputs) from intensification on dairy farms has met with increasing community concern about the environmental footprint of the dairy industry. In some other countries, dairy farmers who have intensified by increasing nitrogen inputs are now faced with legislation controlling the amount of fertiliser nitrogen that they can use.
