Urban agriculture (UA) is increasingly recognized as a key component of sustainable cities. Commercial farmers in urban areas benefit from a large customer base, short transport distances, and access to diverse sales channels. However, high pressure on land resources makes it difficult for farmers and decision makers to find suitable areas for UA. This study ranks urban and peri-urban farmland areas based on their suitability for urban agriculture (UA) and identifies opportunities for extending the area for UA to currently unused farmland. Through collaboration with urban farmers, we identified four key themes and eleven criteria, which were weighted for two sales scenarios: on-farm and off-farm. We performed a GIS-based multi-criteria decision analysis (MCDA) and assessed suitability using the technique of order preference similarity to the ideal solution (TOPSIS) on 1×1 km grid cells. By overlaying the suitability maps with presumably unused farmland (PUF), we identified areas with high potential for extending UA. In the City of Bergen, 15.3% (on-farm; off-farm=14%) of the total farmland is both unused and highly suitable for UA, compared to only 2.8% (on-farm; off-farm=2.4%) in Oslo. Assessing the suitability of agricultural land for UA can support spatial planning, protect agricultural topsoil from urban expansion, and help achieve global, national, and local goals for urban farming and sustainable land use.

Rapporten sammenstiller kunnskap om hvilken risiko jordbruksarealer ute av drift har for å bli invadert av fremmede skadelige karplanter. Det utredes også hvilke typer jordbruksarealer som er mest utsatt og hvordan landskapet rundt arealene påvirker spredningsrisikoen. I tillegg gir vi anbefalinger om vurderingskriterier som bør legges til grunn ved prioritering av arealer for tiltak, og hvilke tiltak vi anser å være viktigst i forbindelse med jordbruksarealer ute av drift. Arbeidet er knyttet til tiltak 22 i den gjeldende tiltaksplanen «Bekjempelse av fremmede skadelige organismer. Tiltaksplan (2020-2025)».
