My research was about urban food production within 70-km radius of Melbourne CBD. The data collection period ran from July 2012 to July 2013. This was deliberately designed to capture inter-seasonal yield. In all, 15 households took part in the research and each participant contributed 12 weeks’ worth of data.
The result was impressive. The collective plot size was 1,096 sq.m. with a total yield of 388.73 kg worth of fruits, vegetables, nuts, honey and meat. A total of 1,015 eggs were also recorded. The study found that backyard food production was capable of producing a great diversity of edibles from common kitchen garden herbs to less commonly cultivated fruits and vegetables, as well as less commercially available varieties like amaranth, apple cucumber, acorn squash, butter squash, babaco, cape gooseberry, edible canna, elderflower, gem squash, loganberry, nettle, oca, orache, purslane, rat-tailed radish, viola flower, warrigal green, white mulberry and yacon. In total, 101 different types of nuts, fruits, vegetables were generated during the study period.
Another notable feature was the diverse food growing technologies and practices employed by the participants. One exemplary backyard was established in 2008 using permaculture principle. Measuring 80 sq. m., this particular backyard featured more than 30 fruit trees in addition to over 70 varieties of medicinal plants and herbs. The total yield from this backyard over the 12-week period was 50.23 kg.
The type of produce was broadly segregated into 19 categories, see table below. “Beans” included a wide variety: broad bean, French bean, string bean, etc. Similarly “Citrus” covered grapefruit, lime, lemon, orange, etc.
Entomophagy, the practice of eating insects as a dietary supplement is widely practiced in parts of Asia and Africa, but it is not so common in the Western world. One participant raised tenebrious molitor as part of his backyard food production activity.

With its polyculture, diversity and varying practices, urban food production can contribute to community food security. This study has found that urban food production is a thriving activity within Melbourne metropolitan area, with productive outcomes.
Thank you once again to all the participants. The research would not have been possible without their participation and generosity.
