2017 Landscape Research Group Ltd. Urbanisation is characterised by cycles of activation and obsolescence leaving in their wake an abundance of non-productive space (NPS). Expanding cities report more vacant land than do fixed cities, which report higher structural abandonment. If left untreated, existing NPS can spread to surrounding properties. Using Fort Worth, TX, USA as a case site, this research explores the spatial distribution of NPS using Geographical Information Systems spatial analyses. Directional distributions, time series analyses, spatial assessments using 5-mile buffer increments and weighted suitability models were combined to determine if urban core fragmentation is occurring, despite population and economic growth. Findings indicate that peripheral NPS area decreased but these spaces were redistributed into the urban core. Parcel size and regeneration potential in the city centre also decreased. This has resulted in a fragmented urban core characterised by disconnected and small/irregularly shaped parcels of NPS which are difficult to regeneratean urban shrapnel.
