Speaking at the National Dairy Event in Birmingham, England yesterday, Campbell said the status quo simply delivered poor milk prices, falling production and a growing UK trade deficit in dairy products.
He said producers were committed to being part of a vibrant and thriving dairy sector here in the UK, but that this required a more positive and long-term mindset being adopted by all parts of the dairy supply chain.
Campbell said: "The challenge for the whole UK industry is. Are we going to lose our island mentality and grab a piece of this growth for ourselves? Or are we going to continue to stagnate, give up market share to others and watch as the rest of the world expands to satisfy the increased demand for dairy produce?
"We urgently need a strategy for growth in our dairy sector and that is a markedly different place from where we are right now."
Campbell added: "We are currently 60% self-sufficient in milk and dairy products in the UK and our dairy farmers are receiving the worst milk price in Europe. There are nations that are approaching 110% in self-sufficiency terms and their producers are receiving 4p to 6p per litre more than here. That shows what can be achieved."
He called for a "fair, transparent, market-related price that is on level terms with prices being paid in Europe," and said the NFUS was dicussing this possibility with producers, processors and retailers.
