The event at the Canberra Environment Centre aimed to showcase the best the region had to offer, as well as ways residents can cut down on their carbon footprint.

In addition to the dozens of food stalls on display, there were demonstrations throughout the day on how to cut down on household waste, composting or even beekeeping.

Now in its tenth year, visitor numbers at this year's event were large, despite an overcast day threatening to disrupt it with a downpour.

Among the stallholders was Erin Cooper, who runs Tobellie Hill Produce out of a farm in Kindervale, near Braidwood.

She said this was her first year at the festival, and said it was important to show off what farms in the area can produce.

"There's really been a big push for fresh, local and chemical-free produce in Canberra, not just from individuals, but from restaurants and cafes as well," she said.

"If people started to demand it, then local producers would have a better market to get into."

Ms Cooper has been growing produce such as pumpkins, melons out on the property for the past three years, and said production has been rapidly expanding.

"We have always been growing fruit and vegetables since we used to live in Canberra and grew it in the backyard ourselves," she said.

"This year has been the first year that we have been growing produce on such a large scale and it's been gradually increasing."

As the cooler months roll into Canberra, Ms Cooper said production will now shift to winter produce such as pumpkins or green, leafy vegetables.

She said she hopes events such as the Harvest Festival encourages people to look locally when it comes to their food.

"Less than five per cent of food is grown here in Canberra and it's all mostly shipped in from interstate," Ms Cooper said.

"Once you try fresh produce like this, you can't go back."
