A study of 13 small-scale organic gardens in Australia found that urban agricultural operations produced high yields but were not cost-efficient; using gardening logbooks and gardener survey data collected between November 2015 and May 2017, the authors found that urban gardens produced approximately twice the yield of commercial farms in Australia, but the average cost of materials and labor to produce 1 kg of produce was higher than the cost of purchasing 1 kg of the same produce at local stores.
