Sydney is losing more and more fertile, food-growing land as our city grows outwards. In 2011, just 20 per cent of our fresh food needs were met by local growers – and without proper planning, Sydney will continue to lose productive food growing country, particularly in the expanding north and south-west.  So what are the consequences of this loss? And why is it important we protect our local fertile land? Tess spoke to Laura Wynne from the University of Technology’s Institute of Sustainable Futures “Sydney’s Food Futures” project about the impact climate change will have on our nation’s capacity to grow food, and why producing food locally is important for securing our food supply in the years to come.
