Combined with a farmers' market and food garden tours, the town's first food fair will promote permaculture.

It will also feature the launch of Transition Town Riddell, an initiative asking residents to use local produce and live sustainably.

Special guest, permaculture expert David Holmgren, of Daylesford, will support the launch.

Fair organiser Lyn Godfrey says Riddells Creek chefs will demonstrate their cooking skills and share tips on preserving food and cooking lunch from produce sourced locally.

"On Sunday, there will be eight local food gardens that people can visit in Riddells Creek, all within walking distance of one another," Ms Godfrey said.

The first garden to be visited will be a fully enclosed sustainable garden at Riddells Creek Primary School, which is a joint project of the school and the Riddells Creek Lions Club.

The food fair, a concept initiated by Transition Town Riddell group members, has a focus on health and the benefits of eating local produce.

"It is better to eat what's in season in your area - it tastes better and it's not stored for long periods of time," Ms Godfrey said.

"As oil gets more expensive, it is not going to be economically viable to transport food over the distances we do now."

The fair, at the Riddells Creek Primary School in Main Road, Riddells Creek, will run from 9am-2pm on Saturday and 10am-1pm on Sunday.
