Sustainability of Urban Agriculture: Vegetable Production on Green Roofs

Urban Farm DB summary

Vegetable production on green roofs faces multiple challenges, resulting in minimal current activity despite its potential for urban agricultural sustainability. While intensive green roof systems are considered suitable for vegetable production, extensive systems with shallow-rooted crops like lettuce, kale, and radish show the greatest potential for sustained productivity due to building weight restrictions. Deeper-root crops like tomatoes require constant monitoring of fertility and moisture. Green roofs are not presented as a total solution for urban food provision.
