Assessing land suitability and potential for extending the area for urban agriculture in Norway using GIS-MCDA

Urban Farm DB summary

This study ranked urban and peri-urban farmland areas in Norway based on their suitability for urban agriculture (UA) and identified opportunities for extending UA to currently unused farmland. Through collaboration with urban farmers, four key themes and eleven criteria were identified and weighted for on-farm and off-farm sales scenarios. A GIS-based multi-criteria decision analysis (MCDA) using TOPSIS was performed on 1x1 km grid cells. In the City of Bergen, 15.3% (on-farm) and 14% (off-farm) of the total farmland was both unused and highly suitable for UA, compared to 2.8% (on-farm) and 2.4% (off-farm) in Oslo.
