Potential Economic and Ecosystem Performances of Some Mediterranean Fruit Plants in an Urban Context

This study focuses on the possibility of using fruit tree species, from an urban area in central Italy, to evaluate their possible productive, ecosystem, and economic contribution. The realization of the food forest was conducted through the use of a web app that can evaluate the climatic and ecosystem performance of trees in the city. This simulation can provide the city's government with useful information on the ecosystem and the socioeconomic benefits of planting fruit trees in an urban park. Among the four chosen species, both Ficus carica and Morus nigra showed good potential fruit production of 1300 kg and 865 kg and a CO2 storage of 2.5 and 1.5 tons. The production and economic potentials from selling the fruits of the selected species were evaluated, and the Morus nigra species showed the highest economic value over a 50-year period of about 6000 USD, with an average price of 7 USD/kg. Another positive aspect of edible food forest landscapes is their ability to give rise to an ecosystem and habitat that can attract animals, birds, and wildlife, consequently improving urban ecosystem biodiversity.
