Assessing the potential of urban agriculture at the community scale: Spatial heterogeneity, influencing factors, and planning implications

Urban Farm DB summary

Proposes a method for assessing urban-agriculture potential at the residential-community scale, combining cluster analysis, 3D model reconstruction, multi-criteria decision-making and GIS. Low-density high-rise communities showed the strongest spatial suitability, while high-density low-rise communities scored highest on sustainable potential; overall ranking was low-density high-rise > high-density low-rise > large-footprint pitched-roof > old communities. Construction year was the key factor, with building density, gross floor area and roof slope shaping potential via sunlight, planting area and accessibility.
