Intensive dairying is profitable only because it is not bearing the full costs of its production systems, Dr Lees said in a news post on the university website (HERE).
“It is not paying the cost to the environment of its production. We are all picking up the tab and especially our children for the impact on our waterways and climate,” he said.
“Currently intensive dairy farming is addicted to high production per cow. This means adding in concentrated feed such as palm kernel and high levels of nitrogen fertiliser. This increases costs, which means these systems are only profitable with high production and high commodity prices.”
Dr Lees said this shows New Zealand’s future is not in maintaining our position as the lowest cost producer of meat and dairy products.
“The longer that the beef and dairy industries hold on to a commodity model based on increasing output and lowering costs the greater will be the future farmer pain.
“I think we need to have conversations around ‘peak cow’ and the future of our animal production industries.”
He said the Labour Government is clearly signalling New Zealand’s future is not in commodities.
“Facing up to ‘peak cows’ will benefit New Zealand and farmers in the long term. It is either some pain now or a lot of pain later.
“If not alternative proteins will take out our commodity agricultural products in the same way nylon took out wool as a fibre.”
Minister Parker has said there is potential to change towards cropping, horticulture, which are high-value land uses, Dr Lees noted.
“He is right to say there are too many cows, however the potential for cropping and horticulture to replace dairying is simply not going to happen.
“There is no way horticulture and cropping can replace any significant portion of dairy farming land even if it was suitable for horticulture and cropping, which it mostly isn’t.”
Dr Lees said cropping and horticulture land takes up about 2.5 per cent of New Zealand’s total land (422,400 ha). About 1.7 per cent of that is in grain crops and less than 1 per cent for growing fruit and berries. In comparison dairy takes up about 20 per cent (2.6 million ha).
However, there is potential for the horticulture sector to increase the value of our exports. The horticulture industry already produces $5.6 billion in exports from just 200,000 ha. This is in comparison to the dairy industry producing $13 billion from 2.4 million ha.
Dairying can also learn from the sheep industry.
NZ reached peak sheep at 60 million in 1984, Dr Lees pointed out.
Now we have only 30 million but produce the same volume of lamb at significant higher value.
Fewer animals mean less greenhouse gasses and reduce nitrate leaching.
There is the potential to see this happen in the dairy industry also.
