How can dairy farmers reduce their environmental impact?
The need to reduce the environmental impact of agriculture, including dairy production, requires changes in the management strategy and methods of production of dairy systems. Dairy farms need to be managed as ‘whole’ systems with the environmental impact of the system, sustainability and efficiency of production per unit of dairy product, and animal welfare standards, all being important factors. In the future, systems will need to be more sustainable and less reliant on the importation of purchased concentrate feeds. Many plant species can be grown on the farm to produce either forage or combinable grain crops with the potential to improve the energy or protein content of the diet. However, many of these species have not been evaluated fully or subjected to breeding programmes to improve their key traits and more research is required to exploit fully the potential of these plants. Globalisation and the removal of trade barriers indicate that the milk price paid to dairy farmers will continue to be low irrespective of whether the milk is destined for the liquid or processing markets. This trend suggests that dairy farmers may have to consider new strategies to ensure their businesses remain viable in the future. One option is to minimise costs by establishing larger dairy units where milk volume and low production costs are the key factors with the milk sold and marketed away from the farm. An alternative option that is increasingly being undertaken is to both produce and process the milk within the same business, with the marketing of the dairy products aimed at niche markets that will often be within the same geographical location as the dairy farm. Niche markets require high-quality products and further research is required to improve the shelf life of dairy products, enhance flavour and establish a closer link between the producer and consumer. This improves the understanding of the ‘whole system’ and boosts confidence in the benefits dairy products can provide in the human diet.

Does drought increase yield?
As a matter of fact, in drought years, it increases yield, since the additional carbon stored in soil helps it to hold more water. In wet years, the additional organic matter in the soil wicks water away from plant roots, limiting erosion and keeping plants in place.
