Dairy prices were a 'hot topic' at the World Dairy Summit last week, and with on-going market instability in China, New Zealand's dairy industry is struggling. Prices rebounded in the past three Global Dairy Trade auctions, but farming leaders say there's still a long way to go, after record low prices last month. And as new competitors, global food demand and world population grow, how we produce food and maintain competitve in the world market is key. Distinguished Professor Paul Moughan is from Massey University and is the director of the Riddet Institute. He's giving a series of talks in Auckland and Wellington next month, to discuss how and what New Zealand could do to protect its future.
