Productive function of urban gardening: estimate of the yield and nutritional value of social gardens in Prato (Italy)

Urban Farm DB summary

Semi-structured interviews with participants in the "social gardens" of Prato, Italy — plots the municipality assigns to individual pensioners or unemployed people for growing vegetables for home consumption — examined demographic and socio-economic characteristics, cultivated crops, and plot areas. The typical gardener was male, retired, averaged 74 years old, and had a low level of education. A 50 m2 plot with 40% of its area cultivated was estimated to yield about 90 kg of vegetables per year, roughly 61.5% of one person's fruit and vegetable needs. Tomatoes occupied more than 80% of the cultivated area. Vitamin C and Vitamin A showed the highest nutrient contributions, while calcium and sodium showed the lowest.
