The working group "Adaptation to Climate Change" at the Leibniz-Institute
for Agricultural Engineering Potsdam-Bornim (ATB) is introduced. This group
calculates the water footprint for agricultural processes and farms,
distinguished into green water footprint, blue water footprint, and dilution
water footprint.
The green and blue water demand of a dairy farm plays a pivotal role in the
regional water balance. Considering already existing and forthcoming climate
change effects there is a need to determine the water cycle in the field and
in housing for process chain optimisation for the adaptation to an expected
increasing water scarcity. Resulting investments to boost water productivity
and to improve water use efficiency in milk production are two pathways to
adapt to climate change effects.
In this paper the calculation of blue water demand for dairy farming in
Brandenburg (Germany) is presented. The water used for feeding, milk
processing, and servicing of cows over the time period of ten years was
assessed in our study. The preliminary results of the calculation of the
direct blue water footprint shows a decreasing water demand in the dairy
production from the year 1999 with 5.98×109 L/yr to a water demand
of 5.00×109 L/yr in the year 2008 in Brandenburg because of
decreasing animal numbers and an improved average milk yield per cow.
Improved feeding practices and shifted breeding to greater-volume producing
Holstein-Friesian cow allow the production of milk in a more water
sustainable way. The mean blue water consumption for the production of 1 kg
milk in the time period between 1999 to 2008 was 3.94±0.29 L.
The main part of the consumed water seems to stem from indirect used green
water for the production of feed for the cows. |
