Residents' perceptions and valuations of urban wastelands are influenced by vegetation structure

摘要

Among the different urban green spaces, wastelands are valuable spaces for conserving urban biodi-versity. By hosting wild and spontaneous vegetation, wastelands can promote the contact citizens have with nature. However, lack of regular management can lead to negative perceptions. In this study we assessed perceptions, valuations and uses of wastelands by residents in two cities in the centre of France. We tested whether preferences for wastelands depended on where wastelands were located in the city, plant community characteristics or resident characteristics. The study investigated 18 wastelands, in three successional stages (initial grassland, intermediate grassland and shrubbery stages) and located in three categories of distance from the city centre (downtown, suburban, periurban). Vegetation was sampled in each wasteland and several plant community metrics were calculated. A total of 72 residents (4 per wasteland) living in the vicinity of the wastelands were interviewed about their use, valuations and perceptions of wastelands. Based on qualitative and quantitative analyses, the results highlighted that a significant proportion of residents (36%) conducted various activities in wastelands and that perceptions and valuations of wastelands were diverse, ranging from either negative (when wastelands were perceived as wild or abandoned areas) or positive (when wastelands were considered as natural and recreational). Valuations strongly depended on the successional stage, with intermediate grassland-like wastelands being preferred. We found no effect of wasteland location in the city, whereas resident characteristics (age and gender) marginally influenced valuations. This study provides new insights into the determinants of perception and valuations of urban wastelands. Particularly, we suggest that intermediate grassland-like wastelands could be easily integrated into urban planning both for recreational activities and conserving biodiversity. Alternatively, awareness of the value of initial grassland-like and shrubbery wastelands should be raised to improve their acceptability. (c) 2017 Elsevier GmbH. All rights reserved.
